Title: A Study of the Grant Writing Policies and Practices of Municipalities in Polk County Florida Having a Population Less Than 25,000.
Creator: Carter, Michael, Jones, Daniel, Flammia, Madelyn, Cameron, Jody, University of Central Florida
Abstract / Description: The purpose of this study is to identify the grant writing policies and practices of the fifteen municipalities in Polk County, Florida having a population less than 25,000, compare these findings qualitatively, and to present the data in a form usable by any city in Polk County so each city can make any needed adjustments to their grant writing strategy that will increase their success of grant funding.

Show moreThe purpose of this study is to identify the grant writing policies and practices of the fifteen municipalities in Polk County, Florida having a population less than 25,000, compare these findings qualitatively, and to present the data in a form usable by any city in Polk County so each city can make any needed adjustments to their grant writing strategy that will increase their success of grant funding. This study is needed now because smaller cities are continuing to feel the effects of the recession, a slumping housing market, and a reduction of real estate property values which means lower tax revenue. City managers and staff need to sharpen their grant writing skills to maximize the success of their grant applications. Both quantitative and qualitative research methodology were used in this study. The quantitative research data was gathered with the aid of a survey sent to each city manager of the selected cities. The qualitative research data consists of follow-up interviews with the fifteen city managers. Fourteen of the fifteen cities responded and all returned surveys were 100% complete. The results of the survey include respondent demographics, a lengthy discussion of each city's attitudes and history with grant application and administration, and the training level of staff involved in grant writing. The chapter goes on to analyze and discuss the policy of local elected officials regarding grants and concludes on the topic of challenges facing Polk County municipalities and possible solutions that may increase their grant writing success. The final chapter brings the study to a conclusion with a summary and a review of the findings from the survey. Several recommendations are offered that, if implemented, could increase the success rate cities are currently achieving with grant applications. Several implications are offered of possible outcomes if no changes are made, and finally, specific areas of future research and study are discussed.

Title: Three Studies of Stakeholder Influence in the Formation and Management of Tax Policies.
Creator: Chen, Jason, Roberts, Robin, Schmitt, Donna, Robb, Sean, Patten, Dennis, University of Central Florida
Abstract / Description: This dissertation consists of three separate but interrelated studies examining the formation and management of tax policies. The first study uses stakeholder theory (ST) to investigate the strategic management practices of the Transport for London (TfL) during discrete stages in the adoption, implementation, and amendments of the tax policy reform known as the London Congestion Charge (LCC).

Show moreThis dissertation consists of three separate but interrelated studies examining the formation and management of tax policies. The first study uses stakeholder theory (ST) to investigate the strategic management practices of the Transport for London (TfL) during discrete stages in the adoption, implementation, and amendments of the tax policy reform known as the London Congestion Charge (LCC). Results indicate that TfL has utilized power, legitimacy, and urgency as its main policy management tactics with a significant emphasis on legitimatizing the LCC and its subsequent policy amendments.The second study draws on social exchange theory (SET) to reexamine the relationship between corporations and legislators during tax policy processes. Data for the study come from publicly available political action committee (PAC) contribution activities surrounding the Energy Independence and Security Act of 2007 (EISA07). By examining the endogeneity between legislators' voting patterns and PAC contributions by corporations, this study aims to refine empirical work on corporate political strategy, especially as it relates to crucial tax provisions embedded within an intensely debated policy proposal. Using simultaneous equations modeling (SEM), results are consistent with SET showing that an implicit and reciprocal relationship exists between corporations and legislators. This relationship affects the interdependence of how legislators vote for public policies and the amount of corporations' financial contributions to legislators.The third study investigates and aims to validate the empirical applicability of Dahan's (2005) typology of political resources in explicating the political interactions between stakeholder groups and legislators in the development of EISA07. I discuss how and why the mode of operations and various political resources employed by stakeholder groups affected the final EISA07 language concerning domestic production deduction tax credits for the oil and gas industry. Publicly available data show that both supporting and opposing stakeholder groups employ tactics consistent with Dahan's (2005) typology. However, both stakeholder groups tend to use an interactive or positive political approach to gain access and favor of legislators instead of an adversarial approach. Ultimately, the tax credits were preserved. Taken as a whole, the three studies advance the tax and public policy research literature in accounting by studying how and why relevant stakeholders affect the formation and ongoing management of public and tax policies.

Show moreDespite an intense focus and considerable financial commitment to remediate non-proficient readers in high school, the large suburban school district that was the target of this study had been unable to consistently improve student achievement in the lowest 25% of students as measured by outcomes on the FCAT Reading. Scholarly literature on high school reading had focused mostly on evaluation of curriculum rather than on teacher practices. A clear understanding of these differences in practice will inform future decisions related to staffing, scheduling, and professional learning. This study sought to identify the underlying professional and instructional differences between the most effective and least effective teachers of tenth grade intensive reading courses through teacher and principal/assistant principal surveys along with teacher evaluation data. This study revealed with regards to a teacher's preparation to teach reading (research question one), that years of experience in the classroom and years of experience as a high school reading teacher were the only significant factors that influenced a teacher's effectiveness. For research questions two and three; which had to do with the beliefs and professional practices of the teacher, the educationally relevant belief that the more effective teachers were more confident about their abilities than their less effective peers was noted. Research question four provided the data with regards to the general classroom teaching strategies and the adolescent reading strategies the effective teachers employed. This data revealed that the more effective teachers implemented posting and communicating daily and long term learning goals more frequently than their less effective peers. In addition, the general classroom teaching practices of efficient use of learning time, establishing and maintaining classroom routines, and checking for understanding proved to be educationally relevant. Additionally, the adolescent reading strategies of sustained silent reading, paired/partner readings, and students reading one-on-one with teacher, were educationally relevant as well. Finally, in regards to research question five, it was of statistical significance that administrators valued the use of the general classroom teaching strategy of posting and communicating daily and long term learning goals and were able to recognize the use of this strategy when observing and evaluating the teachers.?

Show moreThe intent of this qualitative research study was to investigate the experiences of eighth-grade readers as they read nonfiction text on an iPad for academic purposes. Analysis of the Common Core State Standards (CCSS) calls for close reading requiring readers to interact with the text to create meaning (Fisher, n.d.). With this in mind, the researcher investigated reading strategies students used to support their reading as well as what role the iPad features played in the reading process. Several theoretical perspectives informed the framework for this study: (a) New Literacies theory, (b) transactional theory, (c) constructivist theory, and (d) metacognition theory. These perspectives focused on the reading comprehension strategies students used to facilitate reading comprehension while reading nonfiction text on an e-reader, specifically on an iPad. Data sources for this study included the following: (a) retrospective think alouds; (b) student questionnaire about iPad knowledge and experiences; (c) pre-study student interview; (d) post-study student interview; (e) Metacognitive Awareness of Reading Strategies Inventory (MARSI); (f) student observations; and (g) teacher interview. Pre-selection data for the collective case study participants were used to identify proficient readers who displayed confidence, competency, and control over text. The criteria used for participant selection included (a) reading skills using Lexile Levels, (b) MARSI survey, and (c) iPad use survey to determine prior knowledge of iPad. Three themes emerged in the collective case study that were directly related to the analysis. Students used a combination of (a) reading comprehension strategies, (b) nonfiction features, and (c) iPad features to support their reading of nonfiction on the iPad. Analysis of the data revealed three distinct groups for which recommendations were made: (a) classroom teachers, (b) publishers, and (c) researchers.

Show moreThe U.S. Army desires to improve safety during Intelligence, Surveillance, Reconnaissance (ISR) operations by removing Warfighters from direct line-of-fire by enhancing ISR operational capabilities with unmanned systems, also known as Robot-Aided ISR (RAISR) (DOD, 2013). Additionally, RAISR presents an opportunity to fulfill ISR capability requirements of modern combat environments including: detection of High-Value Individuals (HVI) from safer distances, identification of baseline behavior, and interpretation of adversarial intent (U.S. Army, 2008). Along with the demand and projected acquisition of RAISR technology, there is the added need to design training requirements for system operation and task execution instruction. While documentation identifying specific training standards and objectives for ISR tasks utilizing unmanned systems is limited (DOD, 2013), simulation-based training has been identified as a critical training medium for RAISR (U.S. Army, 2008). ISR analysts will primarily conduct RAISR tasks via Indirect Vision Displays (IVD) which transition well into multimodal simulations (Salcedo, Lackey, (&) Maraj, 2014). However, simulation alone may not fulfill the complex training needs of RAISR tasks, therefore, incorporating instructional support may improve the effectiveness of training (Oser, Gualtieri, Cannon-Bowers, (&) Salas, 1999). One method to accomplish this is to utilize a Scenario-Based Training (SBT) framework enhanced with instructional strategies to target specific training objectives.The purpose for the present experiment was to assess the effectiveness of SBT enhanced with selected instructional strategies for a PC-based RAISR training simulation. The specific task type was the identification of HVIs within a group through behavior cue analysis. The instructional strategies assessed in this experiment, Highlighting and Massed Exposure, have shown to improve attentional weighting, visual search, and pattern recognition skills, which are critical for successful behavior cue analysis. Training effectiveness was evaluated by analyzing the impact of the instructional strategies on performance outcomes, including detection accuracy, classification accuracy, and median response time, and perceptions of the level of engagement, immersion, and presence during training exercises. Performance results revealed that the Massed Exposure strategy produced significantly faster response times for one subtle and one familiar target behavior cue. Perception results indicated that Highlighting was the least challenging instructional strategy and the Control offered the preferred level of challenge. The relationships between performance and perception measures revealed that higher levels of engagement, immersion, and presence were associated with better performance in the Control, but this trend did not always hold for Massed Exposure and Highlighting. Furthermore, presence emerged as the primary predictor of performance for select target behavior cues in the Control and Massed Exposure conditions, while immersion and engagement predicted performance of select cues in the Highlighting condition. The findings of the present experiment point to the potential benefit of SBT instructional strategies to improve effectiveness of simulation-based training for behavior cue analysis during RAISR operations. Specifically, the findings suggest that the Massed Exposure strategy has the potential to improve response time when detecting both familiar and novel targets. The results also highlight directions for future research to investigate methods to alter instructional strategy design and delivery in order to improve trainee perceptions of the instruction.

Show moreThe purpose of this study was to investigate the effect of teachers attending Cognitively Guided Instruction (CGI) professional development on students' problem solving strategies and the effect of students' use of strategies on their mathematics achievement as measured by a standardized test. First, the study analyzed the differences in students' use of strategies between treatment and control groups. The treatment was CGI professional development, and the teachers in the treatment group attended CGI workshops whereas the teachers in the control group did not. Next, the study analyzed the differences in the mathematics achievement of students between different strategy groups. A student posttest, which was ITBS (Math Problems and Math Computation), was used to compare students' mathematics achievement. A student pretest was used as a covariate. The results of this study showed that there were statistically significant differences in the students' use of strategies between the treatment and control groups at the second grade level. A greater percentage of treatment students used derived facts / recall strategies (the most advanced strategy for single-digit addition and subtraction) than control students did. The results related to the effect of students' use of strategies on their mathematics achievement showed that the students who used derived facst/recall strategies for single-digit problems had significantly higher mathematics achievement than students who used counting or concrete modeling strategies. Furthermore, the students who used invented algorithms for multi-digit problems had significantly higher mathematics achievement than the students who used standard algorithms.

Show moreOBJECTIVE: An alcohol-drinking culture exists among first-time-in-college students, where many of these students come to their university relatively inexperienced with alcohol, which may increase alcohol-related consequences. Several interventions exist to combat this campus problem. The current study investigates the use of a Deviance Regulation Theory (DRT) intervention, presented in a web-based manner, to increase alcohol Protective Behavioral Strategies (PBS), such as monitoring drinks, using a designated driver, and drinking water in between alcoholic beverages, among college freshmen. METHOD: College freshmen participants (N = 157) completed web-based surveys examining alcohol behaviors once a week for six weeks. Participants were randomly assigned to one of three conditions: a positive frame about individuals who used PBS, a negative frame about individuals who did not use PBS, or a control group that did not receive a DRT intervention. Participants also reported their perception of PBS use among UCF students and friend. Data was analyzed in each PBS subtype: Manner of Drinking, Stop/Limiting Drinking, and Serious Harm Reduction. RESULTS AND CONCLUSION: Results indicate a negatively framed message with high perceived norm levels results in increased PBS use, which may suggest college freshmen have a strong drive to "fit in", or avoid standing out in negative ways. Further, there seems to be little desire to standout in positive ways among first-year students. This may be indicative of individuals who modify their behavior in order to assimilate to a new and unfamiliar environment. Furthermore, some PBS strategies were associated with decreases in alcohol consumption and alcohol-related problems. Results suggest a DRT intervention may be beneficial to first-time-in-college students.

Show moreThe world bond market is nearly twice as large as the equity market. The goal of this dissertation is to study the dynamics of bond price. Among the liquidity risk, interest rate risk and default risk, this dissertation will focus on the liquidity risk and trading strategy. Under the mathematical frame of stochastic control, we model price setting in U.S. bond markets where dealers have multiple instruments to smooth inventory imbalances. The difficulty in obtaining the optimal trading strategy is that the optimal strategy and value function depend on each other, and the corresponding HJB equation is nonlinear. To solve this problem, we derived an approximate optimal explicit trading strategy. The result shows that this trading strategy is better than the benchmark central symmetric trading strategy.

Show moreRecent data indicate that only 34% of American eighth grade students are able to demonstrate grade-level proficiency with academic reading tasks (NCES, 2011). The staggering nature of statistics such as this is even more profound when considering that high level literacy skills combined with mastery of digital texts have become practical requirements for success in secondary education, post-secondary education, and virtually all vocational contexts. Despite this incongruent scenario, little research has been conducted to evaluate instructional methods and reading comprehension strategies with digital texts.To address this critical issue, the present study examined the effects of a metacognitive reading comprehension instructional protocol (STRUCTURE Your Reading [SYR]; Ehren, 2008) with eighth grade students using digital texts in a standard social studies classroom in an urban American school setting. The focus of the protocol was on teaching strategies and self-questioning prompts before, during, and after reading. The study employed a randomized controlled design and consisted of three conditions with a total of 4 participating teachers and 124 participating students. The study was conducted over 25 instructional days and two instructional units with 13.83 treatment hours within the standard, social studies classes. Hierarchical ANCOVA analyses revealed that when controlling for pre-test measurements, the comparison and experimental groups performed significantly better than the control group with instructional unit test scores (Unit 2), reading strategy use in all stages of reading (before, during, and after), and self-questioning prompts during reading. Comparison and experimental groups did not significantly differ in these gains, indicating that this instructional protocol is effective with both paper and digital text. These findings suggest that the SYR instructional protocol is effective with secondary students in content area classrooms when using digital text. Furthermore, they suggest that metacognition and reading comprehension strategy instruction are able to be successfully embedded within a content area class and result in academic and metacognitive gains. Clinical implications and future research directions and are discussed.

Show moreThe purpose of this study was primarily to explore the conceptualization of critical thinking development in radiologic science students by radiography program directors. Seven research questions framed three overriding themes including 1) perceived definition of and skills associated with critical thinking; 2) effectiveness and utilization of teaching strategies for the development of critical thinking; and 3) appropriateness and utilization of specific assessment measures for documenting critical thinking development. The population for this study included program directors for all JRCERT accredited radiography programs in the United States. Questionnaires were distributed via Survey MonkeyÃ‚Â©, a commercial on-line survey tool to 620 programs. A forty-seven percent (n = 295) response rate was achieved and included good representation from each of the three recognized program levels (AS, BS and certificate). Statistical analyses performed on the collected data included descriptive analyses (median, mean and standard deviation) to ascertain overall perceptions of the definition of critical thinking; levels of agreement regarding the effectiveness of listed teaching strategies and assessment measures; and the degree of utilization of the same teaching strategies and assessment measures. Chi squared analyses were conducted to identify differences within each of these themes between various program levels and/or between program directors with various levels of educational preparation as defined by the highest degree earned. Results showed that program directors had a broad and somewhat ambiguous perception of the definition of critical thinking, which included many related cognitive processes that were not always classified as attributes of critical thinking according to the literature, but were consistent with definitions and attributes identified as critical thinking by other allied health professions. These common attributes included creative thinking, decision making, problem solving and clinical reasoning as well as other high-order thinking activities such as reflection, judging and reasoning deductively and inductively. Statistically significant differences were identified for some items based on program level and for one item based on program director highest degree. There was general agreement regarding the appropriateness of specific teaching strategies also supported by the literature with the exception of on-line discussions and portfolios. The most highly used teaching strategies reported were not completely congruent with the literature and included traditional lectures with in-class discussions and high-order multiple choice test items. Significant differences between program levels were identified for only two items. The most highly used assessment measures included clinical competency results, employer surveys, image critique performance, specific course assignments, student surveys and ARRT exam results. Only one variable showed significant differences between programs at various academic levels.

Show moreEvidence-based educational policymaking has become a global phenomenon (Wiseman, 2010). According to the Institute of Education Sciences, evidence-based education is "an integration of the professional wisdom and the best available empirical evidence on making decision about how to deliver instructions" (IES, US Department of Education, 2012). This suggests that best practice requires teachers to ensure that instructional strategies and programs implemented in their classroom have been studied in scientific experiments to determine their effectiveness. The general public, as well as practicing teachers, holds an assumption that educators have knowledge as to what is evidence-based education. However, this is not always the case. The objective of this these include: to document how pre-service teachers access research findings and what types of findings they use in their practice, to identify the purposes of its utilization, to identify the factors that influence research utilization, and to ensure the accessibility of the findings of this study. The population for this study will be pre-service teachers at a large public higher education institution and one state college. In order to meet these objectives I conducted a survey, a pre-service teacher focus group, and an interview with faculty. Research findings will impact pre-service teacher preparation programs and increase our understanding of the link between the researchers and educators

Show morePoor dietary choices and lack of physical activity are two main contributing factors for the increasing prevalence of overweight and obesity in the United States. Overweight and obese individuals are at risk for developing major life-threatening diseases. Weight loss is an effective means for reversing these adverse health effects, and smartphone applications (apps) may be an effective means for supporting weight loss outside of formal clinical settings. This study involved identifying factors that contribute to effective weight loss to compare with functionality commonly found in a sample of calorie counter apps. A content analysis was performed using a design framework that included a conceptual model describing the interaction of behaviors for effective weight loss and functional design requirements based upon behavior change and motivation to achieve weight loss. The requirements were used to analyze the presence of features in a sample of popular calorie counting apps, to infer their capability in supporting users' motivation to achieve weight loss. Results indicated that app features might not provide sufficient support to facilitate effective weight loss. Lack of supportive features affects perceived autonomy, relatedness, and competence, reducing motivation. This study provided guidelines to improve the design of calorie counter apps to include more features that support users as they engage in weight loss behaviors. The guidelines may become practical for use in mHealth apps used as part of formal and informal weight management strategies. Implications for future research involving wearable technologies and the use of gamified design strategies are discussed.

Show moreThis research examines the nature and level of educational computer-based game techniques adoption by Milken Educator Award winning teachers in achieving success in their classrooms. The focus of the research is on their level of acceptance of educational computer-based games and the nature of game usage to increase student performance in the classroom. With Davis' (1985) Technology Acceptance Model (Davis, 1985) as the conceptual framework, the research also examines how teachers' perceptions of educational computer-based games influence their willingness to incorporate these teaching methods in their classroom. The approach utilizes a descriptive survey to develop and evaluate responses from exemplar teachers about the level and nature of their use (or lack thereof) of educational computer-based games and implementation in the classroom. Further, this research seeks to identify successful and unsuccessful techniques in the use of educational computer-based games in the classroom. In addition, data collection and analysis will seek to identify the strength of relationships between content-specific educational computer-based games and subject; educational computer-based games and gender; educational computer-based games and age; etc. A teacher who is exemplary as defined by Milken Educator Awards possesses, "exceptional educational talent as evidenced by effective instructional practices and student learning results in the classroom and school". Survey findings are placed within the Technology Acceptance Model framework developed by Davis.

Show moreFinding optimal configuration of power distribution systems topology is an NP-hard combinatorial optimization problem. It becomes more complex when time varying nature of loads in large-scale distribution systems is taken into account. In the second chapter of this dissertation, a systematic approach is proposed to tackle the computational burden of the procedure. To solve the optimization problem, a novel adaptive fuzzy based parallel genetic algorithm (GA) is proposed that employs the concept of parallel computing in identifying the optimal configuration of the network. The integration of fuzzy logic into GA enhances the efficiency of the parallel GA by adaptively modifying the migration rates between different processors during the optimization process. A computationally efficient graph encoding method based on Dandelion coding strategy is developed which automatically generates radial topologies and prevents the construction of infeasible radial networks during the optimization process. The main shortcoming of the proposed algorithm in Chapter 2 is that it identifies only one single solution. It means that the system operator will not have any option but relying on the found solution. That is why a novel hybrid optimization algorithm is proposed in the third chapter of this dissertation that determines Pareto frontiers, as candidate solutions, for multi-objective distribution network reconfiguration problem. Implementing this model, the system operator will have more flexibility in choosing the best configuration among the alternative solutions. The proposed hybrid optimization algorithm combines the concept of fuzzy Pareto dominance (FPD) with shuffled frog leaping algorithm (SFLA) to recognize non-dominated suboptimal solutions identified by SFLA. The local search step of SFLA is also customized for power systems applications so that it automatically creates and analyzes only the feasible and radial configurations in its optimization procedure which significantly increases the convergence speed of the algorithm. In the fourth chapter, the problem of optimal network reconfiguration is solved for the case in which the system operator is going to employ an optimization algorithm that is automatically modifying its parameters during the optimization process. Defining three fuzzy functions, the probability of crossover and mutation will be adaptively tuned as the algorithm proceeds and the premature convergence will be avoided while the convergence speed of identifying the optimal configuration will not decrease. This modified genetic algorithm is considered a step towards making the parallel GA, presented in the second chapter of this dissertation, more robust in avoiding from getting stuck in local optimums. In the fifth chapter, the concentration will be on finding a potential smart grid solution to more high-quality suboptimal configurations of distribution networks. This chapter is considered an improvement for the third chapter of this dissertation for two reasons: (1) A fuzzy logic is used in the partitioning step of SFLA to improve the proposed optimization algorithm and to yield more accurate classification of frogs. (2) The problem of system reconfiguration is solved considering the presence of distributed generation (DG) units in the network. In order to study the new paradigm of integrating smart grids into power systems, it will be analyzed how the quality of suboptimal solutions can be affected when DG units are continuously added to the distribution network.The heuristic optimization algorithm which is proposed in Chapter 3 and is improved in Chapter 5 is implemented on a smaller case study in Chapter 6 to demonstrate that the identified solution through the optimization process is the same with the optimal solution found by an exhaustive search.

Title: Effects of a Mathematics Graphic Organizer and Virtual Video Modeling on the Word Problem Solving Abilities of Students with Disabilities.
Creator: Delisio, Lauren, Dieker, Lisa, Vasquez, Eleazar, Hines, Rebecca, Dixon, Juli, University of Central Florida
Abstract / Description: Over the last decade, the inclusion of students with disabilities (SWD) in the general education classroom has increased. Currently, 60% of SWD spend 80% or more of their school day in the general education classroom (U.S. Department of Education, 2013). This includes students with autism spectrum disorders (ASD), a developmental disability characterized by impairments in behavior, language, and social skills (American Psychological Association, 2013).

Show moreOver the last decade, the inclusion of students with disabilities (SWD) in the general education classroom has increased. Currently, 60% of SWD spend 80% or more of their school day in the general education classroom (U.S. Department of Education, 2013). This includes students with autism spectrum disorders (ASD), a developmental disability characterized by impairments in behavior, language, and social skills (American Psychological Association, 2013). Many of these SWD struggle with mathematics in the elementary grades; fewer than 20% of SWD are proficient in mathematics when they begin middle school, compared to 45% of their peers without disabilities. Furthermore, 83% of SWD are performing at the basic or below basic level in mathematics in the fourth grade (U.S. Department of Education, 2013). As the rate of ASD continues to increase (Centers for Disease Control, 2013), the number of students with this disability who are included in the general education classroom also continues to rise. These SWD and students with ASD are expected to meet the same rigorous mathematics standards as their peers without disabilities. This study was an attempt to address the unique needs of SWD and students with ASD by combining practices rooted in the literature, strategy instruction and video modeling.The purpose of this study was to determine the effects of an intervention on the ability of students with and without disabilities in inclusive fourth and fifth grade classrooms to solve word problems in mathematics. The intervention package was comprised of a graphic organizer, the K-N-W-S, video models of the researcher teaching the strategy to a student avatar from a virtual simulated classroom, TeachLivE, and daily word problems for students to practice the strategy. The researcher used a quasi-experimental group design with a treatment and a control group to determine the impact of the intervention. Students were assessed on their performance via a pretest and posttest. Analyses of data were conducted on individual test items to assess patterns in performance by mathematical word problem type.The effects of the intervention on SWD, students with ASD, and students without disabilities varied widely between groups as well as amongst individual students, indicating a need for further studies on the effects of mathematics strategy instruction on students with varying needs and abilities.

Show moreThe focus of this research was to investigate the use of a district created formative benchmark assessment in reading to predict student achievement for 10th-grade students on the Florida Comprehensive Assessment Test (FCAT) in one county in north central Florida. The purpose of the study was to provide information to high school principals and teachers to better understand how students were performing and learning and to maximize use of the formative district benchmark assessment in order to modify instruction and positively impact student achievement. This study expanded a prior limited study which correlated district benchmark assessment scores to FCAT scores for students in grades three through five in five elementary schools in the targeted county. The high correlations suggested further study. This research focused on secondary reading, specifically in 10th grade where both state and targeted county FCAT scores were low in years preceding this research. Investigated were (a) the district formative assessment in reading as a predictor of FCAT Reading scores, (b) differences in strength of correlation and prediction among student subgroups and between high schools, and (c) any relationships between reading formative assessment scores and Mathematics FCAT scores. An additional focus of this study was to determine best leadership practices in schools where there were the highest correlations between the formative assessment and FCAT Reading scores. Research on best practices was reviewed, and principals were interviewed to determine trends and themes in practice. Tenth grade students in the seven Florida targeted district high schools were included in the study. The findings of the study supported the effective use of formative assessments both in instruction and as predictors of studentsÃƒÂƒÃ‚ÂƒÃƒÂ‚Ã‚ÂƒÃƒÂƒÃ‚Â‚ÃƒÂ‚Ã‚Â‚ÃƒÂƒÃ‚ÂƒÃƒÂ‚Ã‚Â‚ÃƒÂƒÃ‚Â‚ÃƒÂ‚Ã‚Â' performance on the FCAT. The results of the study also showed a significant correlation between performance on the reading formative assessment and performance on FCAT Mathematics. The data indicated no significant differences in the strength of correlation between student subgroups or between the high schools included in the study. Additionally, the practices of effective principals in using formative assessment data to inform instruction, gathered through personal interviews, were documented and described.

Show moreDigital recordings of three different species of bats were studied in this thesis to determine the forces and moments that were experienced throughout the bat's flight. The recordings were also studied to determine the pursuit strategies that were most effective for the bat to quickly capture its prey. A pursuit strategy is a strategic way to travel that will allow a pursuer to capture/approach their target the quickest. Therefore when a bat utilizes a particular pursuit strategy, it will adjust its position/ direction vector in a particular way that will allow it to approach its target very quickly. Data was collected directly from the video by manual collection utilizing Microsoft Visual Studio to extract frames, collect and record the data. This research was conducted to determine when throughout the flight the bat would experience significant forces and moments. The location and magnitude of the forces were reported along with an explanation of why the bat was experiencing a peak at each specific time. The forces and moments that the bat experienced thought-out the flight pursuit were calculated by relative velocity and acceleration calculations. In all four scenarios the bat experienced forces in relation to rotating its body about its center of mass. Forces were specifically seen when the bat periodically began to rotate its body before the final plunge to capture its prey. Prey avoidance and pursuit strategies were also studied and observed in this thesis which included the constant bearing and the constant absolute target direction. The intent was to determine which pursuit strategy bats use to quickly capture their prey. The constant bearing strategy is utilized to pursue prey moving along a smooth path, on the other hand the Constant Absolute Target Direction (CATD) pursuit strategy is utilized to capture erratically moving prey. For most of the bats analyzed, it was seen that the CATD strategy proved to be the preferred pursuit strategy. CATD was not only adequate for analyzing the pursuit of erratically moving prey but also worked well when analyzing the pursuit of prey that remained stationary. It cannot be fully concluded that bats utilize the CATD strategy to successfully capture erratically flying prey. The angle remains relatively constant but does not exhibit a zero change in angle as by definition. The large forces experienced by the bat were seen when the bat began to rotate its body about its pitch axis or when the bat made a large turn. Moments were seen specifically when the bat began to bank into its last and final turn towards its target.

Show moreThis thesis explores the cultural considerations American technical communicators must address when working with French colleagues and when creating technical documentation for French audiences. A review of the literature on intercultural communication theory was conducted, along with a review of the limited research on technical communication in France and the needs of French audiences. A qualitative online survey of French technical communicators was also conducted. Through this survey, French technical communicators reported on their intercultural beliefs, experiences, and practices, and information, language, and cultural needs.Survey responses were analyzed using inductive thematic analysis. Two main themes were developed as a result of this analysis: the importance of adapting content to French audiences, and the cultural differences between French and American information needs and communication styles. Survey findings were combined with theoretical and practical literature to offer American technical communicators guidance for successful intercultural interactions. This thesis concludes with suggestions for future practice and research in intercultural technical communication.

The models investigate an interactive blend of textually-based linear-sequential approaches and visually-based spatial-simultaneous approaches. The models employ Gestalt-inspired figure-ground segregation models, along with other theoretical models, that demonstrate the dynamic capabilities of images as conceptual tools as well as alternate forms of text. The models encourage an interpretative style with active participants in open-ended, multi-sensory meaning-making processes. The models use the flexible tools of modern technology as approaches to meaning-making with art strategies used for research strategies as well as a means to appreciate reading and writing in the context of an increasingly visual environment.
