This was a qualitative case study focusing on one fourth-grade bilingual teacher and her students. Using theoretical and methodological tools from Communities of Practice and Sociocultural Learning research, I discuss how the teacher and her students co-constructed a community of practice during science. Additionally, this study provides first hand accounts of students' various oral, written, and visually represented stances related to complex issues in science, to describe how the teacher developed her students' linguistic and cultural resources through science. I used participant observation, video and audio recordings, and student classroom artifacts to document social interactions to understand what practices assisted in the co-construction of a community of practice in this particular fourth-grade bilingual classroom. Data analyses revealed that the teacher and her students engaged in practices that fostered the science identity of the bilingual fourth-graders. Further analyses revealed that through the integration of literacy practices with science, the students acquired ways to write, talk, and read, adopting scientific discourse. Important connections between home and school were present as a component of this community of practice. Finally, I found that the work of doing science within this particular classroom was accomplished by drawing upon linguistic resources in both English and Spanish. Engaging in the work of doing science bilingually became an essential characteristic of the co-construction of the community of practice. Implications for bilingual education and elementary science education include acknowledging the importance of utilizing all available linguistic resources to gain content-area knowledge and develop academic biliteracies. Implications for elementary teacher preparation call for training that focuses on the integration of content-area literacies, bilingualism, and home-school connections that value knowledge from home as a starting point for the study of science. / text

This thesis presents a qualitative investigation of the effects of social competence on the participation of students with learning disabilities (LD) in the science learning processes associated with collaborative, guided inquiry learning. An inclusive Grade 2 classroom provided the setting for the study. Detailed classroom observations were the primary source of data. In addition, the researcher conducted two interviews with the teacher, and collected samples of students’ written work. The purpose of the research was to investigate: (a) How do teachers and peers mediate the participation of students with LD in collaborative, guided inquiry science activities, (b) What learning processes do students with LD participate in during collaborative, guided inquiry science activities, and (c) What components of social competence support and constrain the participation of students with LD during collaborative, guided inquiry science activities? The findings of the study suggest five key ideas for research and teaching in collaborative, guided inquiry science in inclusive classrooms. First, using a variety of collaborative learning formats (whole-class, small-group, and pairs) creates more opportunities for the successful participation of diverse students with LD. Second, creating an inclusive community where students feel accepted and valued may enhance the academic and social success of students with LD. Third, careful selection of partners for students with LD is important for a positive learning experience. Students with LD should be partnered with academically successful, socially competent peers; also, this study suggested that students with LD experience more success working collaboratively in pairs rather than in small groups. Fourth, a variety of strategies are needed to promote active participation and positive social interactions for students with and without LD during collaborative, guided inquiry learning. Fifth, adopting a general approach to teaching collaborative inquiry that crosses curriculum borders may enhance success of inclusive teaching practices. / Thesis (Ph.D, Education) -- Queen's University, 2008-04-14 20:05:55.867 / SSHRC

Thesis advisor: Michael Barnett / This mixed method study examined the impact of a LEGO<super>TM</super>-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. This study takes a social constructivist theoretical stance that science learning involves learning scientific concepts and their relations to each other. From this perspective, students are active participants, and they construct their conceptual understanding through the guidance of their teacher. With the goal of better understanding the use of engineering education materials in classrooms the National Academy of Engineering and National Research Council in the book "Engineering in K-12 Education" conducted an in-depth review of the potential benefits of including engineering in K-12 schools as (a) improved learning and achievement in science and mathematics, (b) increased awareness of engineering and the work of engineers, (c) understanding of and the ability to engage in engineering design, (d) interest in pursuing engineering as a career, and (e) increased technological literacy (Katehi, Pearson, & Feder, 2009). However, they also noted a lack of reliable data and rigorous research to support these assertions. Data sources included identical written tests and interviews, classroom observations and videos, teacher interviews, and classroom artifacts. To investigate the impact of the design-based simple machines curriculum compared to the scientific inquiry-based simple machines curriculum on student learning outcomes, I compared the control and the experimental groups' scores on the tests and interviews by using ANCOVA. To analyze and characterize the classroom observation videotapes, I used Jordan and Henderson's (1995) method and divide them into episodes. My analyses revealed that the design-based Design a People Mover: Simple Machines unit was, if not better, as successful as the inquiry-based FOSS Levers and Pulleys unit in terms of students' content learning. I also found that students in the engineering group outperformed students in the control group in regards to their ability to answer open-ended questions when interviewed. Implications for students' science content learning and teachers' professional development are discussed. / Thesis (PhD) — Boston College, 2010. / Submitted to: Boston College.

This ethnographic case study investigated the science practices of teachers at onePUBLIC elementary magnet school in light of how school culture influenced science curriculum design and instruction. The purpose of the study was to address how school culture impacted the school’s overall treatment of science as a viable content area. Key informant teachers were interviewed to explore their personal beliefs and values, teaching, access to materials, and views of the adopted integrated thematic curriculum model and magnet structure. The resulting data, triangulated with informal observation and artifact collection, were analyzed using a theoretical framework that emphasized five interdependent school culture indicators (values, beliefs, practices, materials, and problems). Findings suggest that the school’s culture adversely influenced the treatment of science.

Inquiry-based science instruction is a major goal of science education reform. However, there is little research examining how preservice elementary teachers might be motivated to teach through inquiry. This quantitative study was designed to examine the role of background experiences and an inquiry science methods course on interest in science and interest in teaching science. The course included many activities and assignments at varying levels of inquiry, designed to teach content and inquiry methods and to model effective teaching. The study involved analyses of surveys completed by students in the course on their experiences with science before, during, and at the end of the course. The following questions guided the design of this study and analysis of the data: 1.What science background experiences (school, home, and informal education) do participants have and how do those experiences affect initial interest in science? 2.Among the hands-on activities in the methods course, is there a relationship between level of inquiry of the activity and the motivational quality (interesting, fun, and learning) of the activity? 3.Does the course affect participants’ interest and attitude toward science? 4.What aspects of the course contribute to participants’ interest in teaching science and choice to teach science? Descriptive and inferential analysis of a background survey revealed that participants with high and low initial interest in science differed significantly on remembering about elementary school science and involvement in science related activities in childhood/youth. Analysis of daily ratings of each hands-on activity on motivational qualities (fun, interest, and learning) indicated that there were significant differences in motivational quality of the activities by level of inquiry with higher levels of inquiry rated more positively. Pre/post surveys indicated that participants increased in interest in science and a number of variables reflecting more positive feelings about science and science teaching. Regression analysis found that the best predictors for interest in teaching science were experiencing fun activities in the science methods course followed by the interest participants brought to the course. This study highlights the motivational aspects of the methods course in developing interest in science and interest in teaching science.

Efforts to understand growth and disparities in science achievement have mainly been focused on the middle and high school grades in studies of K – 12 science education, leaving a gap in the research about the early elementary years. This study used a nationally-representative sample of students in Grades K – 2 to examine science achievement and growth trajectories of students by gender and race/ethnicity. Using multilevel growth modeling, differences in science achievement at Grade 2 and in rate of growth were detected for several student groups. Socioeconomic status, prior reading and math achievement, and student home language status were also significant predictors of science achievement. Growth effect size estimates were calculated by student group and showed substantial year-to-year growth in science achievement in the early elementary grades, with a slight decrease in effect size across years. In order to strengthen current efforts to increase student engagement and participation in science and STEM-related career and college pathways, especially for historically underrepresented groups, policymakers should shift focus to better understand promising practices that best support all students in science from the onset of their K – 12 educational experience.

Federal educational policy, No Child Left Behind Act of 2001, focused attention on America’s education with conspicuous results. One aspect, highly qualified classroom teacher and principal (HQ), was taxing since states established individual accountability structures. The HQ impact and use of data-informed decision-making (DIDM) for Texas elementary science education monitoring by campus administrators, Campus Instruction Leader (CILs), provides crucial relationships to 5th grade students’ learning and achievement. Forty years research determined improved student results when sustained, supported, and focused professional development (PD) for teachers is available. Using mixed methods research, this study applied quantitative and qualitative analysis from two, electronic, on-line surveys: Texas Elementary, Intermediate or Middle School Teacher Survey© and the Texas Elementary Campus Administrator Survey© with results from 22.3% Texas school districts representing 487 elementary campuses surveyed. Participants selected in random, stratified sampling of 5th grade teachers who attended local Texas Regional Collaboratives science professional development (PD) programs between 2003-2008. Survey information compared statistically to campus-level average passing rate scores on the 5th grade science TAKS using Statistical Process Software (SPSS). Written comments from both surveys analyzed with Qualitative Survey Research (NVivo) software. Due to the level of uncertainty of variables within a large statewide study, Mauchly’s Test of Sphericity statistical test used to validate repeated measures factor ANOVAs. Although few individual results were statistically significant, when jointly analyzed, striking constructs were revealed regarding the impact of HQ policy applications and elementary CILs use of data-informed decisions on improving 5th grade students’ achievement and teachers’ PD learning science content. Some constructs included the use of data-warehouse programs; teachers’ applications of DIDM to modify lessons for differentiated science instruction, the numbers of years’ teachers attended science PD, and teachers’ influence on CILs staffing decisions. Yet CILs reported 14% of Texas elementary campuses had limited or no science education programs due to federal policy requirement for reading and mathematics. Three hypothesis components were supported and accepted from research data resulted in two models addressing elementary science, science education PD, and CILs impact for federal policy applications. / text

Science "for all" programs have been advanced as the model for introducing and maintaining high standards for science education in every classroom. While standards documents have been an important equalizing force in education for the last twenty years, disparities still exist across multiple student indicators in urban schools. Teaching quality is one of the important factors that contribute to such outcomes and these disparities raise the issue of equitable teaching practices, especially in science. A review of the literature at the intersection of science education and urban education supported the creation of a construct for equitable science teaching that goes beyond content-narrowed "for all" pedagogies to more inclusive "by all" teaching approaches. Scholarship on science teaching in urban settings frequently references reform and efficacy beliefs to bound research questions. The task-specific nature of efficacy beliefs as a construct makes it particularly useful for scrutinizing teaching practices. This dissertation used case study methods to examine aspects of equitable science teaching in an elementary school located in a small urban district in New Jersey. The research design was based on models of collaborative action research. Three key informants in two classrooms helped build understanding of teachers' efficacy-related beliefs about equitable science teaching over the course of one year (Spring 2008 through Spring 2009). Within case and between-case analysis of teaching beliefs and practices were conducted. Key findings from the study suggest that it may be possible to observe change in low efficacy teachers' beliefs over time. Quantitative and qualitative data suggest that it may be possible to build equitable beliefs and practices among in-service teachers. An action plan that includes providing non-evaluative support to teachers in the classroom is discussed. Supports that included immediate feedback, individual and small group reflection and specific tools designed to collect teacher-level data were shown to be important elements for practicing teachers as they worked to build both efficacy beliefs and equitable praxis. Equitable science teaching challenges belief systems but allows for practices to change organically and without prescription. Implications for policy makers, teacher educators, administrators and teachers are discussed. / Urban Education
