Show moreThe focus of this research was to expand on existing literature by providing information on elementary school pre-service teachers' ability to contextualize fraction expressions and decontextualize fraction word problems. The elementary school pre-service teachers who participated in this study were enrolled in a mathematics for elementary school teachers content course in a college of education at a large university during the Spring 2016 semester. In this mixed-method study, the participants were given the Contextualization and Decontextualization of Fractions Instrument (CDFI) which assessed elementary school pre-service teachers' ability to solve fraction word problems and identify decontextualized fraction word problems into expressions and contextualized fraction expressions into word problems. The elementary school pre-service teachers were given the CDFI before and after they completed a unit on fractions. Of the 52 participants who completed both the pre- and post- CDFI, 11 were selected to participant in think aloud interviews in which they decontextualized fraction expressions from word problems and solved and contextualized fraction word problems from expressions. Quantitative results showed an overall statistically significant difference in the elementary school pre-service teachers' pre- and post- test scores. With the exception of two questions, all questions on the CDFI showed a statistically significant difference between the pre- and the post- test scores. No statistical significance was found in the responses to the question that required the elementary school pre-service teachers to identify the expression that matched the given fraction subtraction word problem. A large number of participants correctly identified the correct subtraction expression on the pre-test, and only slightly more of them were able to identify the correct subtraction expression on the post-test. No statistical significance was found in the responses to the question that required the elementary school pre-service teachers to explain their selection of a contextualized fraction multiplication expression. Though there was an increase in the elementary school pre-service teachers' ability to explain their selection of the contextualized fraction multiplication expression, it was not statistically significant. The qualitative analysis of the think aloud interview data showed that some of the elementary school pre-service teachers struggled with contextualizing fraction expressions. Most of the elementary school pre-service teachers did not struggle with solving the fraction word problems, but did struggle with decontextualizing fraction multiplication word problems.

Abstract / Description: Previous research suggested Election 2004 involved many issue regimes and wedge issues (Kaplan, 2004; Drum, 2004; Fagan & Dinan, 2004). Preceding research proposed that the American perception of presidential candidates has been somewhat based on the mass media's increasing priming and agenda setting techniques (Scheufele, 2000; Kiousis & McCombs, 2004).

Show morePrevious research suggested Election 2004 involved many issue regimes and wedge issues (Kaplan, 2004; Drum, 2004; Fagan & Dinan, 2004). Preceding research proposed that the American perception of presidential candidates has been somewhat based on the mass media's increasing priming and agenda setting techniques (Scheufele, 2000; Kiousis & McCombs, 2004). Hence the research addressed two questions: Is there a bias for or against either candidate in the headlines of the Los Angeles Times and the Washington Times? If there is bias, which issues tended to produce the most positive, negative and neutral results? All election headlines, from February to November 2004, pertaining to a specific candidate were recorded and analyzed. The researcher chose to study headlines because they convey the newsworthiness of the story and former research confirms that reader perceptions of a news account can depend on the headline (Pfau, 1995; Tannenbaum, 1953). This study utilized content analysis to assess the word choices and biases of the headlines of the two newspapers. The researcher created definitions for coding, trained two coders, and analyzed and discussed the results. The main findings were the Washington Times contained more headlines that were pro-Bush, while the Los Angeles Times contained more headlines that were pro-Kerry. The key issues that reflected bias included that candidate's campaign, homeland security, and values.

Show moreThis research project will determine whether or not Arab Americans are portrayed as members of an out-group, in-group, or victim following the events of 9/11. This study improves upon previous research by analyzing the content of newspaper articles in USA Today, The New York Times, and The Washington Post pertaining to Arab Americans. Since the majority of research indicated the mass media has a tendency to perpetuate a negative stereotype of minorities and of Arabs, it was expected that the media would portray a negative stereotype of Arab Americans as well. The content analysis addressed the coverage of Arab Americans in the five years before and the five years after 9/11 in order to determine to what extent Arab Americans were depicted as members of an in-group, out-group, or victim following that date. A total of 1379 articles were analyzed placed into the social categories of in-group, out-group, or victim utilizing a clearly defined coding method. Findings showed that overall Arab Americans were depicted as members of an out-group more than they were depicted as members of an in-group or victim. Since the total number of articles dramatically increased following 9/11, the number of articles placing Arab Americans as members of an in-group, out-group, or victim increased accordingly. However, approximately three years after 9/11, the number of articles pertaining to Arab Americans began returning to pre-9/11 levels. While the number of articles placing Arab Americans as members of an in-group or victim increased immediately following 9/11, articles in both social categories steadily declined following 9/11. While the number of articles placing Arab Americans as members of an out-group decreased in the year immediately following 9/11, the number of articles placing Arab Americans as members of an out-group steadily increased following 9/11.

Show moreThe purpose of this study was to examine if differences exist in student learning outcomes between students who are instructed in a co-taught or non co-taught environment in secondary social studies classrooms implementing Content Enhancement Routines (CER). This study examined student and teacher data from seventeen matched pairs of co-taught and non co-taught middle and high school general education social studies teachers who participated in professional development in CER and professional development in co-teaching if applicable. Of the 34 participating teachers, 23 were visited by school district personnel to verify implementation of CER. Five co-teaching teams, each consisting of a general and special educator, completed a Coteaching Rating Scale (CtRS) (n=10) to analyze the level of co-teaching occurring in the classroom (beginning, compromising or collaborating stage). A systematic sample of students (n = 907) completed a CER Student Perception Survey to examine perceived differences of the use of CER in co-taught and non co-taught social studies classrooms. Student state assessment scores (n = 318) in co-taught and non co-taught classrooms were analyzed to distinguish differences in student learning gains. Specifically this study investigated if differences in student performance occur when a special educator is present in the classroom. Results indicate that although there was no statistically significant difference in student learning outcomes between the two settings, the impact of teacher preparation, professional development and the implementation of CER in the secondary social studies classroom may be determining factors in student success.

Show moreThis action research study was conducted with 7th grade life science students at a public middle school in central Florida. The author used Reciprocal Teaching (RT) as described by Annemarie Palincsar and Anne Brown (1984) to examine changes in student comprehension when reading their life science textbook and changes in how the students used the predicting, questioning, and summarizing strategies. The RT strategies ask students to employ 4 strategies: predict what they will read, generate questions about what was read, clarify any ideas that were not understood in the reading, and summarize the main idea of the reading. Students were given a pre and post reading comprehension test, they completed reading response worksheets to record their predictions, questions, clarifications, and summaries. Students were explicitly taught the 4 strategies prior to using them and the strategies were reinforced through teacher modeling (using think aloud teaching to show students how to use the strategies) and expert scaffolding (giving students the support needed while using the strategies). The teacher-researcher also examined if the students showed change in their level of proficiency when using the strategies after they had been taught them. Analysis of data revealed that student comprehension did increase after being taught the four reading strategies. Data also showed that students became increasingly more proficient when using the strategies as the study progressed. Data analysis also uncovered the unexpected pattern of increased student participation during whole-class and reading group discussions. Further research is needed to examine the effects of teaching highly proficient students specific reading strategies and to see how the explicit instruction of reading strategies affects student participation and achievement during inquiry-based laboratory investigations.

Show moreDespite the widespread availability and importance of nonnumeric data, marketers do not have the tools to extract information from large amounts of nonnumeric data. This dissertation attempts to fill this void: I developed a scalable methodology that is capable of extracting information from extremely large volumes of nonnumeric data. The proposed methodology integrates concepts from information retrieval and content analysis to analyze textual information. This approach avoids a pervasive difficulty of traditional content analysis, namely the classification of terms into predetermined categories, by creating a linear composite of all terms in the document and, then, weighting the terms according to their inferred meaning. In the proposed approach, meaning is inferred by the collocation of the term across all the texts in the corpus. It is assumed that there is a lower dimensional space of concepts that underlies word usage. The semantics of each word are inferred by identifying its various contexts in a document and across documents (i.e., in the corpus). After the semantic similarity space is inferred from the corpus, the words in each document are weighted to obtain their representation on the lower dimensional semantic similarity space, effectively mapping the terms to the concept space and ultimately creating a score that measures the concept of interest. I propose an empirical application of the outlined methodology. For this empirical illustration, I revisit an important marketing problem, the effect of movie critics on the performance of the movies. In the extant literature, researchers have used an overall numerical rating of the review to capture the content of the movie reviews. I contend that valuable information present in the textual materials remains uncovered. I use the proposed methodology to extract this information from the nonnumeric text contained in a movie review. The proposed setting is particularly attractive to validate the methodology because the setting allows for a simple test of the text-derived metrics by comparing them to the numeric ratings provided by the reviewers. I empirically show the application of this methodology and traditional computer-aided content analytic methods to study an important marketing topic, the effect of movie critics on movie performance. In the empirical application of the proposed methodology, I use two datasets that combined contain more than 9,000 movie reviews nested in more than 250 movies. I am restudying this marketing problem in the light of directly obtaining information from the reviews instead of following the usual practice of using an overall rating or a classification of the review as either positive or negative. I find that the addition of direct content and structure of the review adds a significant amount of exploratory power as a determinant of movie performance, even in the presence of actual reviewer overall ratings (stars) and other controls. This effect is robust across distinct opertaionalizations of both the review content and the movie performance metrics. In fact, my findings suggest that as we move from sales to profitability to financial return measures, the role of the content of the review, and therefore the critic's role, becomes increasingly important.

In 1933 Proctor developed a laboratory compaction test to determine the maximum dry density of compacted soils, which can be used for specifications of field compaction. The Compaction of soils is influenced by many factors, the most common are the moisture content, the soil type and the applied compaction energy. The objective of this research is the analysis of the maximum dry density values based on the soil classification and characterization. The method of choice in the determination of the maximum dry density from different soils was the Standard Proctor Test following the procedure for the standard Proctor test as is explained in ASTM Test Designation D-698. From this investigation, the maximum dry density of eight types of sands was obtained, the sands were classified by using the Unified Soil Classification System. The influence on the maximum dry density of the type of sands, type of fines, amount of fines and distribution of the grain size was determined, followed by a sensitivity analysis that measured the influence of these parameters on the obtained maximum dry density. The research revealed some correlations between the maximum dry density of soils with the type of fines, the fines content and the Uniformity Coefficient. These correlations were measured and some particular behavioral trends were encountered and analyzed. It was found that well-graded sands have higher maximum dry density than poorly graded when the soils have the same fines content, also it was encountered that plastic fines tend to increase the maximum dry density.

Abstract / Description: The purpose of this study was to determine if three different tests of phonological awareness: the Comprehensive Test of Phonological Processes (CTOPP) (Wagner, Torgesen, & Rashotte, 1999), The Phonological Awareness Test (PAT) (Robertson & Salter, 1997), and the Pre-Literacy Skills Screening (PLSS) (Crumrine & Lonegan, 1999) measure the same phonological awareness skills (content) in the same manner (procedures) and, whether typically-developing kindergarten-age students perform similarly on...
Show moreThe purpose of this study was to determine if three different tests of phonological awareness: the Comprehensive Test of Phonological Processes (CTOPP) (Wagner, Torgesen, & Rashotte, 1999), The Phonological Awareness Test (PAT) (Robertson & Salter, 1997), and the Pre-Literacy Skills Screening (PLSS) (Crumrine & Lonegan, 1999) measure the same phonological awareness skills (content) in the same manner (procedures) and, whether typically-developing kindergarten-age students perform similarly on each of the tests. Twenty-five kindergarten students consisting of 14 males and 11 females (mean CA of 72.24 months) participated in this study. All participants were attending the second half of kindergarten in a public school in Orlando, Florida. Prior to the administration of the three tools, all participants were administered the Fluharty Preschool Speech and Language Screening Test - Second Edition (Fluharty-2) (Fluharty, 2001) to ensure that no formal speech and/or language assessment was needed. A comparison of the CTOPP, PAT, and PLSS revealed that the PAT and CTOPP produced similar outcomes. That is, participants who performed well on one tool also did well on the other. Results of this study have shown that tasks on these two tools are comparable measures of phonological awareness known to strongly predict future reading ability. However, when the PLSS was compared to either the CTOPP or PAT, similar outcomes were not obtained. Three participants were identified "at risk" for reading disability on the PLSS. No participants were identified "at risk" on either the CTOPP or PAT. Using a standardized battery to identify children "at-risk" for reading failure and planning intervention may be more advantageous than using a screening measure like the PLSS. Even though it will take more time to complete, a comprehensive assessment battery may be of more value to the clinician. A summary, possible limitations of study, and suggestions for future research are discussed.

Many communities, including South Florida, are already having the security of their daily lives impacted as climate change causes SLR and other environmental impacts to worsen. This study reviews the Miami-Dade Sea Level Rise Task Force Report to determine how this coastal county government views SLR as a threat. Using mixed content analysis to analyze the report qualitatively and quantitatively, the Task Force's recommendations are categorized based on their focus on security, infrastructure, economics, and the environment. One finds the concerns of the people to maintain their property and infrastructure, as well as their access to water and other basic needs, as insurance costs spike and funding becomes more difficult to obtain. Policies will have to be revised using updated scientific studies, modeling, and mapping to mitigate against the worse-case scenarios.

This study attempts to identify specific patterns of impression management strategies through a deductive content analysis applying Jones' (1990) taxonomy of self-presentation strategies to this particular type of computer mediated communication. Sampling for this study (n=227) was limited to blogs solely and regularly authored by the highest-ranking leaders of Fortune 500 companies. The study revealed that executive bloggers frequently employed impression management strategies aimed at currying competency attributes (self-promotion), likeability (ingratiation), and moral worthiness (exemplification) to construct and shape a positive identify for themselves and their organization for their publics. Supplication strategies were used less frequently, while intimidation strategies were rarely used.

Show moreThis research project aimed to extend the research literature by providing greater insight into the way individual prospective teachers develop their conceptual understanding of whole number concepts and operations in a social context. In this qualitative study, a case study analysis provided the opportunity for careful exploration of the manner in which prospective teachers' understanding changed and the ways two selected participants reorganized their mathematical thinking within a classroom teaching experiment. While previous research efforts insisted on creating a dichotomy of choosing the individual or the collective understanding, through the utilization of the emergent perspective both the individual and the social aspects were considered. Specifically, using the emergent perspective as a theoretical framework, this research endeavor has outlined the mathematical conceptions and activities of individual prospective teachers and thus has provided the psychological perspective correlate to the social perspective's classroom mathematical practices. As the research participants progressed through an instructional sequence taught entirely in base-8, a case study approach was used to select and analyze two individuals. In order to gain a more thorough understanding of the individual perspective, this research endeavor focused on whether teachers with varying initial content knowledge developed differently through this instructional sequence. The first participant initially demonstrated "Low-Content" knowledge according to the CKT-M instrument database questions which measure content knowledge for teaching mathematics. She developed a greater understanding of place value concepts and was able to apply this new knowledge to gain a deeper sense of the rationale behind counting strategies and addition and subtraction operations. She did not demonstrate the ability to consistently make sense of multiplication and division strategies. She participated in the classroom argumentation primarily by providing claims and data as she illustrated the way she would use different procedures to solve addition and subtraction problems. The second participant illustrated "High-Content" knowledge based on the CKT-M instrument. She already possessed a solid foundation in understanding place value concepts and throughout the instructional sequence developed various ways to connect and build on her initial understanding through the synthesis of multiple pedagogical content tools. She demonstrated conceptual understanding of counting strategies, and all four whole number operations. Furthermore, by exploring various ways that other prospective teachers solved the problems, she also presented a greater pedagogical perspective in how other prospective teachers think mathematically. This prospective teacher showed a shift in her participation in classroom argumentation as she began by providing claims and data at the outset of the instructional sequence. Later on, she predominantly provided the warrants and backings to integrate the mathematical concepts and pedagogical tools used to develop greater understanding of whole number operations. These results indicate the findings based on the individual case-study analysis of prospective elementary school teachers and the cross-case analysis that ensued. The researcher contends that through the synthesis of the findings of this project along with current relevant research efforts, teacher educators and educational policy makers can revisit and possibly revise instructional practices and sequences in order to develop teachers with greater conceptual understanding of concepts vital to elementary mathematics.

Show moreIt has been estimated that one third of the world's population does not have access to "adequate" health care. Some 1.6 billion people live in countries experiencing "concentrated" acquired immune deficiency syndrome (AIDS) epidemics. Many countries in Africa -- and other low-income countries -- are in dire need of help providing adequate health care services to their citizens. They require more hands-on care from Western health workers -- and training so more African health workers can eventually care for their own citizens. But these countries also need assistance acquiring and implementing both texts -- the body of medical information potentially available to them -- and technology -- the means by which that information can be conveyed. This dissertation looks at these issues and others from a multi-faceted approach. It combines a survey of the developers of Web sites designed for use by health workers in low-income countries and a proposal for a novel approach to communication theory, which could help improve health communication and other social marketing practices. It also includes an extensive review of literature regarding a number of topics related to these issues. To improve healthcare services in low-income countries, several things should occur. First, more health workers -- and others -- could visit African countries and other places to provide free, hands-on medical care, as this researcher's group did in Uganda. Such trips are ideal occasions for studying the cultural differences between "mzungu" (white man) and the Ugandan people. A number of useful medical texts have been written for health workers in low-income countries. Others will be published as new health information becomes available. But on what medium will they be published? Computers? Personal digital assistants? During the past 10 years the Internet became an ideal venue for conveying information. Unfortunately, people in target countries such as Uganda encounter cultural differences when such new technologies are diffused. This dissertation looks at cultural and technological difficulties encountered by people in low-income countries who attempt to diffuse information and communication technologies (ICT). Once a technology has been successfully adopted, someone will look for ways to use it to help others. There are hundreds of sites on the Internet -- built by Web developers in Western countries -- that are designed for use by health workers in low-income countries. However, these Web developers also experience cultural and technological differences, based on their knowledge of and attitudes toward best practices in their field. This research includes a survey of Web developers which determined their attitudes toward best practices in their field and tested this researcher's hypothesis that there is no significant difference among the developers' attitudes toward the content on their sites, their audience's cultural needs and the various technological needs their audience has. It was found that the Web developers agree with 17 of 18 perceived best practices and that there is a significant difference between Web developers' attitudes toward their audience's technological needs and their attitudes toward quality content and the audience's cultural needs. Creation of the survey herein resulted in this researcher generating a new way of thinking about communication theory -- called digital research cycles. The survey was based on a review of literature and is rooted in the belief that any successful communication of a computer-mediated message in the information age is a behavior which is influenced by the senders' and receivers' attitudes and knowledge about textual style, the audience, technology and the subject matter to which the message pertains.

Show moreThis dissertation in practice establishes roles and responsibilities for K-12 mathematics coaches in a rural, urban school district in central Florida. To do this, coach roles and responsibilities from existing coaching approaches were examined. The roles and responsibilities were closely examined for alignment with the objectives of the work of the coach (-) improving instruction and increasing student achievement. The result was proposed roles and responsibilities for K-12 mathematics coaches in a targeted district in central Florida. Review of the literature found that clearly delineated and communicated roles and responsibilities are vital to the success of mathematics coaches. Poorly defined and/or communicated roles and responsibilities result in barriers that prevent the coach from meeting the objectives of his/her job: improving instruction and student achievement. Clearly established and communicated job responsibilities for mathematics coaches positively impact the effectiveness of the coach, resulting in support for teachers and students and, in turn, a positive impact on student achievement. Research suggests that in addition to instructional practices, teachers also need support in content knowledge, curriculum, assessment, and data analysis.

Show moreEnhancing achievement in Science, Technology, Engineering, and Mathematics (STEM) is a long-standing national concern. The current national agenda, to instill an (")all hands on deck(") approach to creating a STEM literate citizenry, calls for broadening the scope of inclusion in STEM efforts. A critical population, higher education administrators, faculty, and staff are a valuable resource to advancing this agenda. Under the proposed Agenda Setting Communication Theory (ASCT) model developed for this study, their level of exposure to needed information is an important indicator of their potential participation in this agenda. As the leading news medium for the higher education community, the Chronicle of Higher Education was examined, through Content Analysis, to identify the frequency of reporting on STEM education from January 2001 to December 2015, to discern the themes in STEM education which appear in the Chronicle of Higher Education from January 2001 to December 2015, and to determine the frequency of reporting on the need for collaboration in STEM education in the Chronicle of Higher Education during that same period. The results of the Content Analysis indicate that there has been a significant increase in the Chronicle's reporting on STEM education in the past five years. Also, matters relating to the recruitment and retention of underrepresented populations were reported on most frequently. Further, reporting on the need for collaboration did not emerge as a primary theme. These results indicate that while the Chronicle is somewhat participating in reflecting aspects of the national STEM education agenda, it is not yet functioning to advance the breadth of that agenda within the higher education community.

Show moreThe overall focus of this project has two parts: First, was to develop a protocol utilizing serum-free media formulations and defined plating and culture techniques to create functional in vitro myotubes derived from adult skeletal muscle satellite cells. The second was to manipulate the inherent muscle parameters such as force output and fatigue of these myotubes by employing exercise regimes or by small molecule application. The importance of serum-free medium use for in vitro cultures is becoming increasingly important in creating functional systems that can be validated for drug testing by the Food and Drug Administration (FDA). Also, the study of age related diseases as well as the potential for (")personalized medicine(") relies on the proliferation and maturation of satellite cells from adult derived tissue. For that purpose, a serum-free medium and culture system was designed to create mature striated myotubes in culture on a defined non-biological substrate N-1[3-trimethoxysilyl propyl] diethylenetriamine (DETA). These myotubes were evaluated by morphology, muscle specific protein expression, and by muscle functionality. After the thorough characterization of the resultant myotubes the functional output of the muscle was altered utilizing chemical means (creatine supplementation and PGC-1? agonists), chronic long term stimulation, and the use of PGC-1? deficient tissue. In this thesis presentation the utility of the newly developed medium formulation to create myotubes from a variety of adult derived muscle sources will be shown. A protocol in which to exercise skeletal muscle in vitro to alter endurance was developed and employed to manipulate skeletal muscle. Finally, small molecules were tested to validate this system for drug study use. This engineered system has the potential for high-throughput screening of drugs for efficacy and drug toxicity studies as well as general biological studies on muscle fatigue.

Show moreABSTRACTThis study was conducted to examine whether a disparity exists between teacher expectations of honors and non-honors U. S. History students and if students who read more for U. S. History perform better on the U. S. History End-of-Course (EOC) examination. To generate answers to the research questions, both teachers and students in U. S. History courses were surveyed as to how much time was spent reading for U. S. History content both during class and for homework. The student surveys were matched to the U. S. History EOC Developmental Scale Scores to determine if students who responded as reading more for the course had higher achievement on the EOC examination. Five teacher surveys were completed, and 144 student surveys were analyzed, and comparisons were made using U. S. History EOC Developmental Scale Scores. Teachers surveyed did not appear to vary their expectations of student whether the students were in an honors or non-honors course. Approximately 71% of non-honors and 73% of honors students in this study were reading U. S. History homework content on a regular basis. Though not statistically significant, results did indicate a positive trend between students who read more for U. S. History content and achievement on the EOC examination. This study revealed the implementation of a standardized EOC examination may account for equally rigorous teacher expectations of both honors and non-honors students. All students have the same final evaluation and expectation of passing the EOC; therefore, all students are expected to learn the content.

Show moreClassroom teachers deal with numerous pressures in their classrooms including students' difficulty with reading at the middle and high school levels. Often, teachers can identify the problems, but are often unable to rectify them because of a lack of understanding and support in incorporating reading as part of their content area instruction. This research was conducted to investigate the impact of a sustained, online reading professional development on the teaching practice of middle school and high school science teachers who took the 14-week course. This grounded theory research used the reflective assignment, a comprehensive, 10-week, job-embedded assignment of 62 science teachers, to generate categories and themes about the reading challenges they perceived in their own classrooms, what strategies and tools they chose to remedy those challenges, and the perceived changes they saw in their students and themselves. The theory that was derived from the data speaks to how effective, job-embedded reading professional development can impact the knowledge, motivation, and instructional practice of science teachers in the classroom.
