Show moreThe purpose of this study was to determine if a relationship existed between the implementation of a computer science immersive learning experience and achievement on the Florida Standards Assessment (FSA) English Language Arts (ELA) or the FSA Mathematics. Two research questions, each with two sub-questions, guided the research of the study. The sub-questions addressed historically underrepresented groups in computer science. These subgroups included African Americans, Hispanics, Mixed Race individuals, and females. Research Question 1 analyzed the relationship between the implementation of the computer science immersive learning experience when a cohort control group design was used. Research Question 2 determined if a relationship existed when the treatment schools were compared to demographically similar schools that did not receive the treatment of computer science immersion. A two-way analysis of variances (ANOVA) was run for each of the research questions with the subgroups of students used as moderators for the treatment. Statistical significance was found for the following groups; fourth grade ELA Hispanic cohort, fourth grade Hispanic mathematics cohort, third grade ELA cohort, third grade mathematics cohort, the ELA treatment group, and the mathematics treatment group. Statistically significant findings showed negative, positive, and neutral effects on the treatment groups. These findings provide implications for the implementation of computer science immersion in other elementary schools with similar student demographic variables. Further investigation is needed to determine other potential impacts on student achievement over time.

Show moreThe purpose of this study was to determine if my practice of having 4th grade students participate in engineering design challenges impacted their attitudes towards engineering, the classroom climate, and writing ability. In this action research students were given a pre and posttest that measured their attitudes towards engineering and their perceptions of the classroom climate. A pre and post written reflection was also examined and compared for the use of predicting, observing, thinking, explaining, reflecting, and yearning to learn more. A triangulation of data included the use of pre and posttest statistical analysis, rubrics, teacher observation, and student interviews. The data collected from this action research project showed that that students were more satisfied with the course after completing the design challenges, the classroom environment improved in that students perceived the level of friction in the class had decreased. The data collected also showed that students' attitudes towards engineers was changed in that they were more likely to want to pursue a career in engineering and take a future school course in engineering after having completed this action research. Student generated definitions of engineers demonstrated a decrease in the number of misconceptions about the work of engineers and an increase in students' knowledge as to what engineers do for a living. My practice of implementing engineering design challenges with a 4th grade class did not have an impact on students writing ability.

Show moreThis study attempted to verify points of intersection (POIs) between mathematics and science in the eighth grade Sunshine State Standards (SSS), and to develop a valid and reliable instrument to evaluate these POIs as they were presented in the respective mathematics and science textbooks approved for use in Florida public schools. Shannon and Weaver (1998) delineated a process for content analysis that informed the design of this analysis. The process began with an analysis of the SSS to uncover POIs between mathematics and science; considered effective strategies for presenting these points of intersection in the classroom; and examined the textbooks for a mutually supportive presentation of the POIs between the two domains. The criterion for textbook evaluation was synthesized from documents used by the National Research Council (NRC, 2004) and Project 2061 (Roseman, Kulm, Shuttleworth, 2001. These criteria were examined in terms of measureable elements of textbook design, vocabulary, inquiry and problem solving in order to create integrated objectives, which were then operationalized so that each objective could be evaluated using the Textbook Evaluation Document (TED). The validity of the TED was insured by the transparency of the process. Reliability was determined in two steps, first to determine the most reliable segments of the document and finally to confirm the reliability of those segments. It was determined that the vocabulary section of the TED consistently produced reliability scores above 70% with variation of Supportive Curriculum Scores (SCS) between textbooks. This indicated that a measure of supportive vocabulary could be generated for use in future studies for example correlating supportive curriculum with student achievement.

The simulation model, which is based on functional activities, emphasizes the interdependent consequences of decisions and actions created through management planning, analysis, and control of training programs. A simulation experiment was conducted using a test situation description (scenario) to reflect the impact of management decisions and actions on the resulting allocation of resources and timeliness of training program activities. Conclusions are drawn regarding the utility and implications of the system dynamics model as a management tool with which to improve training. Recommendations are made regarding future experimentation and analysis which is required for sufficient development of a useful management tool.

Show moreRecent data indicate that less than 50% of American secondary students are able to demonstrate grade-level proficiency in reading, writing, and science (National Center for Educational Statistics [NCES], 2007, 2011, 2012a, 2012b). Secondary students' are expected to develop advanced literacy skills, especially in writing, in order to be ready for college and careers. Students are expected to develop these advanced literacy skills, within all academic subjects. In other words, they are expected to develop disciplinary literacy skills. The statistics are alarming overall, but they are particularly alarming in the area of science. Students need strong literacy skills, including written expression, to be prepared for employment opportunities in science fields, which currently are being filled by graduates of other industrialized nations, who have a more advanced skill set. This loss of occupational opportunity poses a threat for the U.S. to remain globally competitive in science innovation and advancement, which ultimately secures economic prosperity. Despite these staggering concerns, there is little research conducted to evaluate effective instructional methods to develop complex writing skills in academic disciplines such as science.To address this critical issue, the present study examined the effects of a metalinguistic approach to the writing intervention of sentence combining with eighth-grade students who struggle with literacy. The researcher conducted the study in a typical science classroom in an urban American school setting. The focus of the intervention was to increase students' metalinguistic awareness of science text, to improve written sentence complexity in science, as well as the written expression and determination of comparison and contrast of science content. The study employed a quasi-experimental design. The participants consisted of an experimental group (two classes) who received the treatment during typical science instruction and a comparison group (three classes) who did not receive treatment, but participated in their typical science instruction. There were four participating teachers and 84 participating students. The researcher conducted the study over a period of seven weeks within regularly scheduled science classes. Twenty intervention sessions were conducted for a length of 20 minutes each, totaling 400 minutes or 6.6 hours. Hierarchical repeated measures ANOVA and hierarchical repeated measures MANOVA analyses revealed that the experimental group performed significantly better than the comparison group on their ability to determine similarities and differences (compare and contrast) related to science content, with a medium effect. The experimental group achieved a slightly higher marginal mean over the comparison group on their ability to combine sentences, with a small effect. Multiple statistical analyses revealed a trend of higher marginal means in favor of the experimental group over the comparison group on several measures of written sentence complexity on both the science compare and contrast writing prompt (small-medium effect) and the science expository essay (medium to large effect). One experimental class also demonstrated higher scores in their overall sentence correctness on science expository essay as compared to all the other classes. These findings suggest that sentence combining, utilizing a metalinguistic approach, may hold promise as an effective writing intervention in a content area classroom, for secondary students who struggle with literacy. Furthermore, the findings suggest that a metalinguistic approach to sentence combining can be successfully embedded within a content area class, which may result in increased concept knowledge and writing skills in that academic discipline. Implications for practice and future research directions are discussed.

Show moreEffective teacher questioning during whole group instruction remains an important pedagogy in science education, especially the importance of helping novice teachers to guide student thinking using effective questions. This study examined how novice secondary science teachers' understand the relationship between student thinking and teacher questioning. The sample was seven novice secondary science teachers' enrolled in the University of Central Florida's job embedded Resident Teacher Professional Preparation Program (RTP3). All participants received instruction and guided practice with the use of questions to elicit, probe, and challenge student ideas in the secondary science pedagogy class. Participants completed a questionnaire describing their teaching experience and science content knowledge. The primary data were think aloud interviews describing their thinking while observing two science instruction videos. Protocols, critical incident interviews, and field notes were transcribed and coded for analysis. Descriptive codes identified properly classified question types and the purpose or value of questions, student thinking, and student reaction to teacher questions. Pattern codes identified student engagement, feedback, wait time, and communication patterns. The think aloud used in this study provided insight into what the participants were thinking about the purposes of questions to elicit, probe, and challenge student ideas and gave insight into the decision process. Evidence from the protocol analysis provided insight about what the participants were thinking about the decisions made when attending to teacher questions and student thinking. All seven participants identified question types using language suggesting they understood the differences, but at a na(&)#239;ve level. Although participants used the correct language to show understanding of the question types, they had a fairly na(&)#239;ve understanding of the pedagogical purpose of the questions. This was especially true of the questions to elicit student ideas, but perhaps less true of the probing and challenging questions. The participants had more of a ritualistic understanding of the questions to elicit student ideas; they noticed them but perhaps did not have a deep understanding of this question type. Analyses of this study also revealed novice teachers learning is framed by the priorities of the public school system. All participants attended to teacher instruction, especially wait time and student engagement, while a few participants focused on feedback, praise, and higher- and lower-order questions. This study suggested school culture and the way teachers are now assessed may scaffold and support these teachers to have a more nuanced and sophisticated understanding of questioning and student thinking than has previously been reported for novice/beginning teachers. While some aspects of school culture and assessment may be problematic- i.e. wait time, feedback, praise, higher-order questions, etc.-on the whole it seems to be leading them in the right direction.

Show moreAttosecond pulses have been developed as a means for investigating phenomena that proceed on the order of the atomic unit of time (24 as). Unfortunately, these extreme ultraviolet (XUV) pulses by themselves contain too few photons to initiate nonlinear dynamics or dress states in an attosecond pump--attosecond probe scheme. As a result, most attosecond experiments thus far have featured complementary near infrared (NIR) femtosecond lasers for instigating electron dynamics. In order to access the benefits of all-attosecond measurements and open attosecond physics to new fields of exploration, the photon flux of these pulses must be increased.One way to boost the attosecond pulse energy is to scale up the energy of the NIR pulse responsible for driving high-harmonic generation (HHG). With generalized double optical gating (GDOG), isolated attosecond pulses can be generated with multi-cycle laser systems, wherein the pulse energy can be boosted more easily than in the few-cycle laser systems required by other gating methods. At the Institute for the Frontier of Attosecond Science and Technology (IFAST), this scalability was demonstrated using a 350 mJ, 15 fs (10 TW) Ti:sapphire laser, which was used to generate a 100 nJ XUV continuum. This represented an order-of-magnitude improvement over typical attosecond pulse energies achievable by millijoule-level few-cycle lasers.To obtain the microjoule-level attosecond pulse energy required for performing all-attosecond experiments, the attosecond flux generated by the IFAST 10 TW system was still deficient by an order of magnitude. To this end, the laser system was upgraded to provide joule-level output energies while maintaining pulse compression to 15 fs, with a targeted peak power of 200 TW. This was accomplished by adding an additional Ti:sapphire amplifier to the existing 10 TW system and implementing a new pulse compression system to accommodate the higher pulse energy.Because this system operated at a 10 Hz repetition rate, stabilization of the carrier-envelope phase (CEP) -- important for controlling attosecond pulse production -- could not be achieved using traditional methods. Therefore, a new scheme was developed, demonstrating the first-ever control of CEP in a chirped-pulse amplifier (CPA) at low repetition rates.Finally, a new variation of optical gating was proposed as a way to improve the efficiency of the attosecond pulse generation process. This method was also predicted to allow for the generation of isolated attosecond pulses with longer driving laser pulses, as well as the extension of the high-energy photon cut-off of the XUV continuum.

Show moreIgnitable liquids consist of either a single organic compound or a complex organic mixture. In regards to fire debris analysis, the analyst is responsible for determining if an ignitable liquid residue is present. However, when extracted from soil-containing fire debris evidence, chemical degradation from microorganisms is observed to result in the loss of compounds based on chemical structure. It can also happen when the evidence container is stored at room temperature before analysis. This can present a challenge to the fire debris analyst when identifying and classifying the ignitable liquid residue based on the criteria established by standard test methods. The purpose of this research was to observe the microbial degradation of fourteen compounds, at room temperature over a period of time, for possible by-product formation that could coincide with compounds normally present in an ignitable liquid. Additionally, a quantitative assessment was performed to observe and record the loss rate of compounds in a representative simple mixture. Finally, the loss rate from the simple mixture was compared to commercially available ignitable liquids. Degradation studies were conducted to observe the microbial degradation of a representative compounds (individually and in a simple mixture, both weathered and unweathered) and seven ignitable liquids of different ASTM E1618 classifications. Potting soil was spiked with 20 (&)#181;L of a liquid/compound and was allowed to stand at room temperature for a period of time. The simple mixture was evaporated to 50% and 90% using a steady nitrogen gas flow to compare the degradation process to the unweathered mixture. All samples were extracted and analyzed using passive-headspace concentration and gas chromatography-mass spectrometry.The formation of by-products was not observed when degrading the compounds from the simple mixture individually as seen in other research. The simple mixture, unweathered and 50% weathered, resulted in rapid degradation of their oxygenated compounds. The straight-chained alkanes and toluene were observed to be more susceptible to microbial attack than the highly-substituted aromatics and the branched and cyclic alkanes. The 90% weathered mixture followed the same degradation trend as the unweathered and 50% weathered samples, although it only contained two compounds. The loss rates/half-lives for each simple mixture sample (unweathered, 50% weathered, and 90% weathered) were determined to be approximately 3.5, 3.5, and 0.84 days. The unweathered and 50% weathered sample half-lives were similar due to containing compounds with similar susceptibility to degradation, while the 90% weathered sample contained one compound that was more highly susceptible to degradation. When comparing the 3.5 day half-life to the seven different ASTM class liquids, the isoparaffinic product and the naphthenic-paraffinic product had similar rates of degradation while aromatic solvent and normal alkane classes had the shortest half-lives. When observing the degradation of the gasoline, medium petroleum distillate and the miscellaneous, the constituent compounds were seen to exhibit a range of degradation rates that corresponded to half-lives less than and greater than 3.5 days.

Show moreScientific literacy has been at the forefront of science education reform for the past 20 years, particularly for students from culturally and linguistically diverse (CLD) backgrounds (Lee et. al., 2005; Pearson, Moje (&) Greenleaf, 2010). The ability to extract meaning from text is an important skill. Yet many students struggle with effectively comprehending what they read, particularly in content areas of science, math and history. According to the National Assessment Educational Progress (NAEP, 2013) report, adolescents are not acquiring advanced literacy skills needed to succeed in the workplace and academic setting. Literacy experts have called for the use of disciplinary literacy approaches to engage learners with the content in ways that mirror what scientists, historians and mathematicians do to gain understanding in their disciplines (Moje, 2006; Shanahan (&) Shanahan, 2008). Although disciplinary literacy instruction is promising, there is limited empirical research on the effectiveness of discipline-specific literacy approaches. The present study examined the effects of a metalinguistic approach on the comprehension of science text among African American 5 and 6th grade students. The focus of the instructional protocol was to explicitly teach adverbial clauses and assist students to unpack adverbial clauses through the use of a graphic organizer. The process of unpacking complex sentences aimed to facilitate comprehension of science text by engaging the participants in analysis and discussion of the meaning obtained from the adverbial clauses. This study employed an experimental single-case multiple-probe across participants design. Visual Analysis (VA) and the Improvement Rate Difference (IRD) were used to analyze the data. The results of VA and IRD indicated that all participants demonstrated progress between baseline and treatment phases. Overall, the results of the investigation suggest that it is possible for 5th and 6th grade African American students to benefit from instruction that closely analyzes language. Clinical implications and future research directions are discussed.

Show moreThe present study explores the nature and structure of spiritual and aesthetic experiences through the interdisciplinary application of neurophenomenology (NP). This approach merges aspects of psychology, neurophysiology, and phenomenology into a unified methodology. The study is nested within a larger project, Space, Science, and Spirituality, and as such, it carries a common goal to use simulation to evoke spiritual and aesthetic responses similar to those expressed by astronauts and cosmonauts. Careful analysis of previous work in NP provided methodological (")lessons learned("), which guided the experimental design, execution, and analysis of the present study. The data collected provides support for experience as a phenomenon that can be studied through empirical means. Further, the articulation of spiritual and aesthetic experiences akin to astronaut experiences corresponds to specific neurological and psychological indicators. Among those indicators are differences in EEG measures during simulation time relative to expressions of spiritual experience following the simulation and changes in visual processing across theta, alpha, and beta signals as correlated with self-identification. These findings support an embodied theory of experience that incorporates memory, executive function, perception, and consciousness. In addition to its academic contribution, this research holds implications for commercial space flight, long-term space missions, post-traumatic stress disorder therapies, and the entertainment industry.

Show moreThis thesis outlines the high intensity tabletop attosecond extreme ultraviolet laser source at the Institute for the Frontier of Attosecond Science and Technology Laboratory.First, a unique Ti:Sapphire chirped pulse amplifier laser system that delivers 14 fs pulses with 300 mJ energy at a 10 Hz repetition rate was designed and built. The broadband spectrum extending from 700 nm to 900 nm was obtained by seeding a two stage Ti:Sapphire chirped pulse power amplifier with mJ-level white light pulses from a gas filled hollow core fiber. It is the highest energy level ever achieved by a broadband pulse in a chirped pulse amplifier up to the current date.Second, using this laser as a driving laser source, the generalized double optical gating method is employed to generate isolated attosecond pulses. Detailed gate width analysis of the ellipticity dependent pulse were performed. Calculation of electron light interaction dynamics on the atomic level was carried out to demonstrate the mechanism of isolated pulse generation.Third, a complete diagnostic apparatus was built to extract and analyze the generated attosecond pulse in spectral domain. The result confirms that an extreme ultraviolet super continuum supporting 230 as isolated attosecond pulses at 35 eV was generated using the generalized double optical gating technique. The extreme ultraviolet pulse energy was ~100 nJ at the exit of the argon gas target.

The Prologue Past is a collection of four essays and one novella which explore the past in different fashions. Memory, and the ability to reflect and find meaning in our experiences, is an important cornerstone of engaging the past. Memories are a true anomaly of how our inner-consciousness operates. With each day, the past facilitates a special part of our memory bank which we seldom have any control of. While the abilities of people to recall times, events, places, and experiences differ...
Show moreThe Prologue Past is a collection of four essays and one novella which explore the past in different fashions. Memory, and the ability to reflect and find meaning in our experiences, is an important cornerstone of engaging the past. Memories are a true anomaly of how our inner-consciousness operates. With each day, the past facilitates a special part of our memory bank which we seldom have any control of. While the abilities of people to recall times, events, places, and experiences differ largely in capacity, we all undoubtedly share universal traits in the manner in which we hold onto our memories. I'm personally fascinated by the notion of unreliable memory or the inability to recall a past event in a concrete moment in time. I'm equally intrigued by what's tied to our most vivid recollections of the past, involving adrenaline and emotion. My exploration of memory(-)and how it's ascertained and utilized(-)is based on certain moments in my life presented in these personal stories, which range from childhood endeavors to adult conquests, seemingly linked together through particular themes of fear, loss, and hope.

Show moreUniversity of Central Florida College of Arts and Sciences Thesis; Tennessee ratified the Nineteenth amendment by a margin of one vote. This study, therefore, examines Tennessee, its politics, and its politicians to see to what extent the usual historical explanations that states' rights and the liquor and railroad industries were the main obstructions to Tennessee's ratification of the Nineteenth Amendment. It concludes that women's increased access to education and employment affected too few women in the state to cause a great demand for the vote. Moreover, corporate opponents and racist fears were less important as impediments to ratification than historians have believed. Legislators voted neither out of fear of federal intervention, nor from party loyalty; they considered each issue on its merits. Whether it was good for the state, their constituents, and their own political careers seem likely reasons for their decisions. Woman suffrage hung in the balance until the last possible minute so that one vote eventually determined the outcome in Tennessee.

Show moreUniversity of Central Florida College of Arts and Sciences Thesis; The development and birth of the Orange County Regional History Center is perhaps unlike any other local history museum in the United States. Its story is worth telling because of its long gestation, the difficulties in bringing this center to life, and the goals of the people who made it possible. All of these elements are a vital part of the history of Orange County, Florida and should not be overlooked. In this light, this thesis will discuss more fully three topics in relation to the creation of the new History Center. First, it will look at the American museum field and its role as a community-building enterprise in American society. Second, it will examine the history of Central Florida, a region that sorely lacks a strong sense of community. Third, it will trace the transformation of the Orange County Historical Society and Museum from a small volunteer-run museum into the Orange County Regional History Center, the largest history museum in Central Florida. The ultimate goal of the History Center is to foster a sense of community in a region with little feeling of connectedness. This community building goal has evolved from both a renewed emphasis on community service in the museum field, and the desire of the History Center's leaders and staff to serve more effectively the Central Florida region. My thesis tells the story of the history and development of the Regional History Center, an institution dedicated to bringing the diverse community of Central Florida together for discussion, dialogue, and reflection. It also identifies some of the new roles and functions it must assume in the future and the new tasks that await it as it strives to become more useful and relevant to its community. In that way, and through that resource, the institution can help build the foundation for a more promising future for present and future residents of Orange County.

Show moreThe purpose of this study was to find the effectiveness of digital storytelling technology integration through a project-based learning approach using digital stories combined with hands-on guided inquiry science lessons. As a teacher researcher, the focus was on the effectiveness in the performance of second-grade students using higher-order thinking science standards. For a period of ten weeks, the researcher through comparative action research investigated how emergent technology integration improved the performance of two second-grade classrooms implementing three higher-order thinking life science standards. A total of 27 students from two second-grade classrooms volunteered for this research. For the study, a pretest and posttest from Classroom A and Classroom B were utilized for the quantitative data analysis. A web-based rubric was created to assess the science digital story and student journals. The students also completed a self-assessment progression scale at the end of the study. The data collected showed an improvement in the performance of second-grade students using higher-order thinking science standards with technology integration.

Show moreIn order to study the teaching and learning of the theory of evolution and determine levels of acceptance of the theory of evolution among college students studying biology in Central Florida, the Inventory of Student Evolution Acceptance, I-SEA, was administered to over 500 university students enrolled in a biology course during the Fall 2016 term. An analysis of 489 completed surveys demonstrated strong overall acceptance of the theory of evolution (average score = 103 out of 120 total possible). Of all students, 78% fell into the category of very high acceptance of the theory of evolution. Students who reported attending worship services weekly or more scored statistically significantly lower on the I-SEA than students who reported attending worship services less than weekly. The level of previous high school coursework in biology(-)whether honors, or advanced biology courses were taken-- did not translate into statistically significant differences in acceptance of evolution as measured by the I-SEA. Three subscales contained within the Inventory of Student Evolution Acceptance are designed to measure student acceptance of microevolution, macroevolution, and human evolution. Students demonstrate higher levels of acceptance of microevolution than macroevolution or human evolution. These findings serve to inform educational leaders and science educators regarding students' worldview and how worldview may inform what students accept as true and valid. The I-SEA serves as a useful educational tool to inform instructional decisions in the biology classroom.

Research has shown that the benefits of having a populace literate in science are great. Even if citizens are not literate in basic science, it is important that citizens still appreciate science and those with expertise in the field for many reasons. Recent research suggests that the United States (U.S.) has lower levels of science literacy than it should. Evidence may also suggest that many U.S. citizens are not appreciative of science.

Show moreResearch has shown that the benefits of having a populace literate in science are great. Even if citizens are not literate in basic science, it is important that citizens still appreciate science and those with expertise in the field for many reasons. Recent research suggests that the United States (U.S.) has lower levels of science literacy than it should. Evidence may also suggest that many U.S. citizens are not appreciative of science. Overall, little research has been conducted on what may predict science literacy and science appreciation which is the aim of this research. Specifically, I have examined socio-personal variables, beliefs, thought paradigms, and various demographic variables that may be predictive of science literacy and science appreciation. Results indicated that scriptural literalism, religiosity, and magical ideation were predictive of low levels of science literacy. In addition, predictors of low levels of science appreciation included scriptural literalism and magical ideation. Implications of the findings are discussed.
