This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing awareness that creativity can be expressed by every student; creativity can be enhanced; science has a much wider range of activities that foster creativity; and creativity-centered science teaching can be implemented in Korea. The major elements of the professional program that promoted these perceptual changes included hands-on creativity activities, observation of creativity-centered classrooms, and discussion with other teachers. Follow-up study revealed that their perceptual changes have been reflected in their teaching practices. 相似文献

Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students’ practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that occurred over eleven class periods; students’ group writings; interviews with six target students and the teacher; and the researcher’s field notes. The results revealed five salient trends in students’ development of oral and written argumentative practices over time: (1) Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; (2) by challenging each other’s arguments, students came to focus on the coherence of the argument and the quality of evidence; (3) students came to use evidence to defend, support, and reject arguments; (4) the quality of students’ writing continuously improved over time; and (5) students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students’ development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices. 相似文献

Research on teachers’ professionalism and professional development has increased in the last two decades. A main focus of this line of research has been the cognitive component of teacher professionalism, i.e., professional knowledge. Most of the previous studies on teacher knowledge—such as the Learning Mathematics for Teaching (LMT) (Hill et al. 2004), the Professional Competence of Teachers, Cognitively Activating Instruction, and Development of Students´ Mathematical Literacy (COACTIV) (Baumert et al. 2010), and the Mathematics Teaching in the 21st Century (MT21) (Schmidt et al. 2007) studies—have been conducted in the field of mathematics teachers’ pedagogical content knowledge (PCK) and content knowledge (CK). There have been few comparable studies conducted with science teachers, especially biology teachers. To fill the gap, this study examines the development and use of instruments to measure biology teachers’ CK and PCK. In particular, this study describes a method to develop reliable, objective, and valid instruments measuring teachers’ CK and PCK in four steps by the use of empirical data of students. Additionally, the study explores whether CK and PCK might be measured as separate knowledge categories by using a paper-and-pencil test. This paper presents a theoretical model that guides test development and provides steps to develop and validate the instruments. Details are also provided regarding the computation of the Rasch scale score measures for 158 biology teachers. The results indicate that the instruments measured teachers’ CK and PCK in an objective, valid, and reliable way. This suggests that the new instruments can be used in combination with classroom observations to examine teaching quality and further its relation to student learning. 相似文献

There is growing recognition in the education community that the problem-solving practices that comprise computational thinking (CT) are a fundamental component of both life and work in the twenty-first century. Historically, opportunities to learn CT have been confined to computer science (CS) and elective courses that lack racial, ethnic, and gender diversity. To combat this inequity, a number of scholars have proposed integrating CT practices into core curriculum——especially science, technology, engineering, and math curriculum. Successfully achieving the goal of integrated CT, however, depends on frameworks to guide integration, professional development for teachers, exemplars of successful integrations, and identifications of the barriers teachers encounter. Research pertaining to each of these areas is in its infancy. This study addresses these needs through a collective case study of 10 secondary science teachers' implementations of a novel, process-based, unplugged approach to CT/science integration and the factors that supported or hindered their CT/science integration efforts. The results of this work reveal that: (1) an unplugged and process-based approach to CT/science integration shows promise as a vehicle for infusing CT into diverse science classrooms; (2) educators' teaching context exerts a strong influence on their CT-integration efforts and persistence; and (3) special attention is needed to support teachers in their CT/science integrations including algorithm creation. This study also demonstrates the utility of the Fraillon et al.'s CT framework as a guide for CT/science integration efforts and sheds light on the unique affordances of unplugged strategies for implementing CT-integrated science curricula. 相似文献

In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice.
An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom
practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues
that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations.
Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs’
beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science.
The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious
to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they
encourage teachers to implement reformed teaching practices. 相似文献

This study examined elementary preservice teachers’ beliefs about the role/image of a science teacher and science teaching
and how these beliefs change during an elementary science methods course; this examination was conducted through an analysis
of their metaphor writing. Data included personal metaphors and rationale papers for supporting them collected from 106 participants
at the start and end of the semester. Data were analyzed using the constant comparative method and also quantified for statistical
analysis. Results indicate that most participants came to the course with traditional views and developed more constructivist
views during the course. However, they tended to keep their traditional views and added new constructivist perspectives into
their original belief systems. This study suggests that metaphor writing can be used as both a reflection tool for preservice
teachers to clarify and refine their beliefs about science teaching and learning and a diagnostic assessment tool for teacher
educators to understand their students for tailoring a methods course accordingly. 相似文献

This study examined how instructional challenges presented by gifted students shaped teachers’ instructional strategies. This
study is a qualitative research grounded in a social constructivist framework. The participants were three high school science
teachers who were teaching identified gifted students in both heterogeneously- and homogeneously-grouped classrooms. Major
data sources are classroom observations and interviews. Data analysis indicated that these science teachers developed content-specific
teaching strategies based on their understanding of gifted students, including: (a) instructional differentiation, e.g., thematic
units, (b) variety in instructional mode and/or students’ products, (c) student grouping strategies and peer tutoring, (d)
individualized support, (e) strategies to manage challenging questions, (f) strategies to deal with the perfectionism, and
(g) psychologically safe classroom environments. 相似文献
