Show moreThe purpose of the study was to explore and describe the perceptions of several elementary science mentors and their mentees within one school district based on a five-factor mentoring model. Utilizing a qualitative methodology in the form of a case study, five mentors and three mentees were interviewed using a structured protocol. From verbatim interview data and field notes, three themes pertaining to the role of the mentor within elementary science emerged as emotional support, technical support, and educative support. Within the five-factor mentoring model, personal attributes suggested notions of support and expert status as critical elements for effective mentoring. The factors of system requirements, pedagogical knowledge, modeling, and feedback were found to be interrelated amongst themselves and with the factor of personal attributes. Effective mentors demonstrated a commitment to the role as well as a flexibility pertaining to role adjustment depending on the context of the mentoring relationship.

Show moreThe purpose of this research study was to determine whether the use of science reform instructional methods had an effect on student participation in and attitudes towards science education. The participants in this 12 week study were third grade students. Data were collected using a pre and post attitudinal survey, student journals, a participation log, and a researcher reflection journal. Several conclusions were made. The use of science reform instructional methods did affect student participation and attitudes towards science. Student journals indicated that students enjoyed the use of technology, hands-on science equipment, working in pairs or small groups and the opportunity to share their ideas and learn from their classmates. This study does lend itself to additional research. Due to the small sample size, the shortened time for research, and the population, these research questions should be investigated with another group of students in order to make more definitive decisions regarding the methods to use in their classroom. If the research is conducted again using a different group of students, a larger population will be needed, as well as a lengthened period for research.

Show moreThe National Science Education Standards (1996) indicate that science education should include inquiry instruction. Many teachers still struggle with how to implement inquiry in their classrooms and a lack of high quality inquiry-based instructional materials has been posited as a hindrance. The purpose of this qualitative study was to observe the instructional practices of three elementary teachers when using an inquiry-based science kit program in their fourth grade classrooms. Teacher practices and their attitudes towards their preparedness to teach science with the support of the curricular program were examined. Data were collected through pre/post survey comparisons, observations, and a focus group session. Results indicated that these teachers' attitudes were positively impacted. Teachers' access to science kits provided resources which facilitated more inquiry experiences with their students; however, resources alone did not fully address teacher science content needs.

Show moreThis dissertation studied the beliefs and practices of principals, workshop site coordinators, and science support personnel in two Central Florida school districts and compared those beliefs and practices to the literature on effective science in-service education. It is important to understand these beliefs and practices because they directly affect the content and pedagogical knowledge of classroom teachers, yet this aspect of instructional practices has been ignored in the science education literature. This study used a grounded theory methodology using open-ended individual interviews, participants observation, and documented analysis. Constant comparisons were built through analyzing the data. The research shows that in-service providers' and administrators' beliefs are aligned with the effective science education in-service literature. The conditions and context are ripe for changes because principals and workshop site coordinators' beliefs are aligned with the literature and changes are already beginning to take place. The intervening conditions may lead to improved teacher knowledge, teaching, and learning because standardized testing is expanding to incoporate the content area of science. Also workshop site coordinators are trying to set up a variety of opportunities to attend workshops on the same topic throughout the school year. Budgets are being restructured at the school level and district level to incorporate more science content professional development. However, it is too early to show how much improvement there will be in standardized test scores or whether teachers' have a deeper understanding of science content knowledge or effective science instruction.

Show moreThe current study details the creation of a new scale for measuring preservice teachers' positive affect for science, the Preservice Elementary Teacher Affect Scale for Science (PETAS-S). This new instrument is designed specifically to measure the level of positive affect towards the subject of science in preservice elementary teachers. Confirmatory factor analysis reveals the instrument loads on the single factor, positive affect. Reliability is robust, with Cronbach's alpha of .96. Positive affect has shown to predict future levels of engagement in domain specific academic subjects (Ainley (&) Ainley, 2011) and is expected to aid preservice teachers in understanding the complex relationship between their students' interest and enjoyment of science with their own. This research contributes to the important role of emotion in preservice teachers' attitudes toward the subject of science and how it may affect the way they teach it to their future students.

Show moreThis ethnographic study of emerging inquiry-based science instruction in an urban, low socioeconomic elementary school science lab was designed to gain insight into the perspectives of the teacher and students. The study involved a Central Florida elementary school whose population was over 80 percent African-American. In this six month study, the researcher examined the classroom setting of a science lab teacher and her fourth and fifth grade students during a six month period of time. Data sources included interviews, field notes, reflections, and student work , which were used to identify the emerging themes and patterns in the study. The emergent themes were grouped into two categories: the perspective of the teacher and students in the inquiry environment and the microculture of the teacher and students in that environment. The teacher's perspectives on instructional strategies, standard based instructional guidelines, and the realities of teaching in an urban low socioeconomic setting were the major emergent themes. The students' perspectives into environment and sense-making of elementary school students were the other major emergent themes. Chapter I provides background and the significance of the study. Chapter II provides a research of the literature surrounding inquiry-based instruction in science education. Chapter III describes the methodology, specifically the ethnographic approach to this study. A metaphoric journey down the river of perspectives in science lab classroom sets the tone for Chapter IV. This chapter provides a "view from the shore," an introduction to the general background of the elementary school. Chapter V explores the teacher perspectives, and uses vignettes to analyze instructional strategies, questioning, assessment, standards state and district guideline and the realities of teaching. Chapter VI discusses the student perspectives, and uses vignettes to analyze behaviors and actions, responsibility of learners, assessment, and ways of knowing. Chapter VII pulls together conclusions, implications, and recommendations for further research.This study contributes to the total body of research of science education in two ways: 1. It provides student and teacher perspectives on science in an urban, low socioeconomic elementary school. 2. It provides research with a teacher and student perspective of inquiry-based science instruction.

Show moreThis ethnographic case study investigated one elementary school to understand how the school's culture influenced its science curriculum design and instruction. The main data was formal and informal semi-structured interviews with key teachers to understand their values, beliefs, practices, materials, and problems with science instruction. To triangulate these data, the researcher observed classroom practice, school-wide activities, and collected artifacts and documents. Data were analyzed using a theoretical framework that emphasizes that culture cannot be reduced to beliefs, values, practices, materials or problems, but rather each aspect of culture is interdependent and mutually reinforcing. The main finding suggests that the school's culture is organized to accomplish other curricular goals than effective science education. Science is rarely taught by most teachers and rarely taught well when it is. While the teachers know the rhetoric of effective science education and value it enough to not dismiss it entirely, most value it less than most other subjects and they are not proficient with science instruction and materials. This study builds upon the literature by reiterating that school culture plays a central role in elementary science education, but adds to that literature by emphasizing that culture cannot be reduced to one or a few factors and must be seen as an organic whole.

Show moreDisparities between males and females in attitudes toward science have been the focus of extensive investigations. Studies have found that females feel intimidated by their male peers in science and mathematics classes, making girls less likely to participate. Their confidence in these areas decreases and they become less likely to follow related career paths. Researchers and educators are at task to find methods to provide equal learning opportunities for all students. The purpose of this action research was to investigate the effects of single-gender grouping and inquiry-based teaching on girls' participation and attitude in science class. This study took place in a second grade classroom at a suburban school in the fall of 2005. Surveys and interviews were used to investigate students' attitudes before and after working with inquiry learning single-gender groups. Using observations, female students' participation was recorded according to the kind of participation they exhibited – passive/assisting, active/leading, or active/manipulating. Students maintained journals to record their understanding of science content and rated the lessons. In addition to improving female students' attitudes towards science, inquiry learning fostered an increase in active student participation. Six out of the eight female students perceived that girls participated more in single-gender groups during the study than they did before the study in their regular mixed-gender groups. However, they did not report a change in their own participation in relation to their peers after working in single-gender groups. Further research with control groups was suggested with a larger and more socio-economically diverse population.

Show moreAs advocated by the National Research Council [NRC] (1996) and the American Association for the Advancement of Science [AAAS] (1989), a change in the manner in which science is taught must be recognized at a national level and also embraced at a level that is reflected in every science teacher's classroom. With these ideas set forth as a guide for change,this study investigated the fifth grade students' understanding of force and motion concepts as they engaged in inquiry-based science investigations through the use of the 5E Learning Cycle. The researcher's journey through this process was also a focus of the study. Initial data were provided by a pretest indicating students' understanding of force and motion concepts. Four times weekly for a period of 14 weeks, students participated in investigations related to force and motion concepts. Their subsequent understanding of these concepts and their ability to generalize their understandings was evaluated via a posttest. Additionally, a review of lab activity sheets, other classroom-based assessments, and filmed interviews allowed for the triangulation of pertinent data necessary to draw conclusions from the study. Findings showed that student knowledge of force and motion concepts did increase although their understanding as demonstrated on paper lacked completeness versus understanding in an interview setting. Survey results also showed that after the study students believed they did not learn science best via textbook-based instruction.

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.

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 moreABSTRACT The purpose of this action research project was to determine how my practice of implementing Universal Design for Learning-Representation (UDL-R) principles influenced my studentsÃ‚Â' understanding of content and enhanced their ability to organize their knowledge using concept maps. A secondary purpose of this action research project was to determine if student created concept maps served as a useful tool to enrich studentsÃ‚Â' written scientific explanations. Students in this study completed concept maps and wrote explanations about adaptations before and after participating in lessons enriched with UDL-R principles that included the use of multi-media sources, website searches, and trade books. The processes used to collect data for this action research project were concept maps, written explanations, student notes, and videotaped accounts of learning from UDL-R principles. The themes that emerged were deeper content understanding for students and greater engagement in learning through UDL-R practices as evidenced through student notes, student discussions and videotaped accounts. The students in this study showed minimal change in the total average scores on concept maps with mixed results for males versus female studentsÃ‚Â' scores. Although studentsÃ‚Â' concept maps and written explanations indicated minimal improvement or change, their notes listing thirty to over one hundred facts and their comments indicated their interest and engagement in the learning process supported by UDL-R practices.

The researcher taught inquiry based student level science lessons to the fourth grade teacher. The teacher participant, in turn, taught those same lessons to her class while the researcher observed and took field notes. The participant responded to specific open ended questions in a journal after each science experience and also completed three interviews with the researcher. Each sequential lesson from the researcher was then modified based on participant needs. The participant completed the STEBI (Science Teaching Efficacy Belief Instrument) as a pre and post test to measure the effects of the above mentioned activities. The collected data from the STEBI was reported quantitatively. The collected data from the reflective journal entries and interviews were reported qualitatively. After careful analysis of the data gathered for this case study, the researcher came to the conclusion that inquiry based professional development through the use of a mentor affected the alternatively certified elementary teacher's science teaching self-efficacy. The subject maintained a positive attitude about the use of a mentor for the duration of the study and her Personal Science Teaching Efficacy increased or stayed the same on all of the STEBI questions. Limitations of the study as well as recommendations for further research were also discussed.

Show moreThis study examined how intermediate elementary students' mathematics and science background knowledge affected their interpretation of line graphs and how their interpretations were affected by graph question levels. A purposive sample of 14 6th-grade students engaged in think aloud interviews (Ericsson & Simon, 1993) while completing an excerpted Test of Graphing in Science (TOGS) (McKenzie & Padilla, 1986). Hand gestures were video recorded. Student performance on the TOGS was assessed using an assessment rubric created from previously cited factors affecting students' graphing ability. Factors were categorized using Bertin's (1983) three graph question levels. The assessment rubric was validated by Padilla and a veteran mathematics and science teacher. Observational notes were also collected. Data were analyzed using Roth and Bowen's semiotic process of reading graphs (2001). Key findings from this analysis included differences in the use of heuristics, self-generated questions, science knowledge, and self-motivation. Students with higher prior achievement used a greater number and variety of heuristics and more often chose appropriate heuristics. They also monitored their understanding of the question and the adequacy of their strategy and answer by asking themselves questions. Most used their science knowledge spontaneously to check their understanding of the question and the adequacy of their answers. Students with lower and moderate prior achievement favored one heuristic even when it was not useful for answering the question and rarely asked their own questions. In some cases, if students with lower prior achievement had thought about their answers in the context of their science knowledge, they would have been able to recognize their errors. One student with lower prior achievement motivated herself when she thought the questions were too difficult. In addition, students answered the TOGS in one of three ways: as if they were mathematics word problems, science data to be analyzed, or they were confused and had to guess. A second set of findings corroborated how science background knowledge affected graph interpretation: correct science knowledge supported students' reasoning, but it was not necessary to answer any question correctly; correct science knowledge could not compensate for incomplete mathematics knowledge; and incorrect science knowledge often distracted students when they tried to use it while answering a question. Finally, using Roth and Bowen's (2001) two-stage semiotic model of reading graphs, representative vignettes showed emerging patterns from the study. This study added to our understanding of the role of science content knowledge during line graph interpretation, highlighted the importance of heuristics and mathematics procedural knowledge, and documented the importance of perception attentions, motivation, and students' self-generated questions. Recommendations were made for future research in line graph interpretation in mathematics and science education and for improving instruction in this area.

Show moreThe purpose of this study was to investigate the impact of an intervention on teaching science as argument within a science methods course on elementary preservice teachers' (PSTs') (a) understandings of the nature of science (NOS), (b) knowledge about argumentation, (c) complexity of their written explanations, and (d) ability to incorporate components of the framework for teaching science as argument to support students' literacy and science learning. This mixed-methods study utilized an embedded quasi-experimental design with a treatment (n = 20) and control group (n = 25). The treatment group instructor, who completed an eight-week professional development course, implemented the intervention protocol across a 12-week period. Throughout the intervention, emphasis was placed on three key components of teaching science as argument (i.e., argument structure, public reasoning, and the language of science). The control group instructor, who did not partake in any professional learning activities, implemented business-as-usual instruction. Results from a repeated measures MANOVA revealed that, although the intervention did not have a significant impact on PSTs' knowledge of argumentation, PSTs who received the intervention did demonstrate a significant increase in their understanding of the NOS and in the complexity of their written explanations, as compared to PSTs who did not receive the intervention. Furthermore, analysis of PSTs' written lesson plans revealed several themes (i.e., opportunities for students to collect and analyze data, use of scaffolds for helping students construct scientific explanations, emphasis on the use of text to support scientific inquiry, and attention to developing students' science vocabulary) consistent with the framework for teaching science as argument. These findings contribute to a growing body of evidence illustrating the effectiveness of intentionally designed teacher preparation experiences for developing PSTs' knowledge, beliefs, and practices for supporting students' engagement in scientific explanation and argument.

Show moreWithin the United States, more than a million jobs in science and engineering (S(&)E) are projected over the next few years; yet, the Nation lacks the workforce to meet these demands. Despite the need for a more diverse, qualified workforce, African Americans/Blacks remain disproportionately underrepresented in science occupations, science degree attainment, and in science postsecondary majors. The lack of science participation is reflective of how minority secondary students view science and science occupations as many consider the pursuit of a science career as unfavorable. Moreover, minority secondary students, who do choose to pursue science occupations, seem to possess inaccurate (or a lack of) occupational knowledge necessary to do so successfully. Therefore, an understanding of antecedents to career choice will assist educational professionals in addressing the underrepresentation of diverse populations, such as African Americans/Blacks, within the science workforce. The purpose of this study is to garner insight into the science occupational images, occupational and educational aspirations of African American/Black fourth and five grade students. Gottfredson's Theory of Circumscription and Compromise, in conjunction with extant empirical literature, serves as the foundation for the study's conceptual framework. A qualitative case study design was used. The qualitative data provided a contextual understanding of science occupational images, occupational and educational aspirations. Participant-produced drawings, questionnaires, and semi-structured interviews served as sources for data collection. Overall, participants lacked some occupational knowledge. Participants viewed scientists as mostly male and Black. Additionally, the occupation of scientist was perceived as a dangerous and of high status. Lastly, half of the participants expressed aspirations to be a scientist, while a majority expressed college educational aspirations.

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.
