Learning to conduct interactive classroom discussions is a high priority for becoming an effective teacher, and most teachers view conducting productive classroom discussions as a complex undertaking. Because the dynamics of facilitating classroom discussions are multifaceted and hard to analyze in real time, there is a growing interest in how video allows preservice teachers to examine records of their practice to promote further growth. What prospective teachers actually take away from analysis of video, however, needs further exploration. In this study, we explored five preservice student teachers’ beliefs about conducting discussions and probed the potential of videocase construction for supporting teacher learning by investigating the following question: ‘To what extent and how does making a videocase help preservice teachers investigate their facilitation of a subject‐specific discussion?’ Results revealed that by constructing and talking about their videocases, all five preservice teachers gained insights about how they lead discussions. Studying video excerpts and articulating what they saw in them provided a context for looking more closely at their own roles and student roles within their discussion. They also recognized the complexities of leading discussions and acknowledged particular areas that need improvement. The teachers used the metaphorical language of ‘guiding’ their students down a pathway when they talked about leading classroom discussions. There were similarities and differences among teachers’ conceptions of good discussions in English and science, and their notions of ‘guiding’ were related to their subject matter goals. The study suggests, however, several areas that may require further attention in preservice teachers’ preparation in leading discussions. Although the teachers expressed views of discussion that aligned broadly with disciplinary views in English or science, their language lacked specificity in what it means to develop varied interpretations of texts in English or consensus based on argument and evidence in science. More specific video analysis focused on subject matter goals and corresponding conversational elements may help preservice teachers develop more nuanced, sophisticated views of how particular types of social interaction have the potential to help their students reach specific subject matter goals. We conclude that investigation is needed on larger numbers of preservice teachers’ videocase construction processes, and further inquiry is needed into how working with video analysis affects their actual performance in future discussion facilitation.  相似文献

In many teacher preparation programs, student teaching serves as a culminating event that bridges academic coursework and the realities of classroom teaching. Therefore, it represents a significant aspect of preservice teacher education. This study explored student teaching as it was experienced by 13 middle and secondary science preservice teachers. Qualitative techniques were used to analyze individual interviews, group seminar sessions, and written reflections to construct a phenomenological account of student teaching as experienced by the preservice teachers. The aim was to construct a picture of the shared experiences of these student teachers to help understand how they struggled, succeeded, and learned as a part of their classroom practica. These findings are then used to draw implications for science teacher education.  相似文献

The current impetus for increasing STEM in K-12 education calls for an examination of how preservice teachers are being prepared to teach STEM. This paper reports on a study that examined elementary preservice teachers’ (n = 21) self-efficacy, understanding of science concepts, and computational thinking as they engaged with robotics in a science methods course. Data collection methods included pretests and posttests on science content, prequestionnaires and postquestionnaires for interest and self-efficacy, and four programming assignments. Statistical results showed that preservice teachers’ interest and self-efficacy with robotics increased. There was a statistically significant difference between preknowledge and postknowledge scores, and preservice teachers did show gains in learning how to write algorithms and debug programs over repeated programming tasks. The findings suggest that the robotics activity was an effective instructional strategy to enhance interest in robotics, increase self-efficacy to teach with robotics, develop understandings of science concepts, and promote the development of computational thinking skills. Study findings contribute quantitative evidence to the STEM literature on how robotics develops preservice teachers’ self-efficacy, science knowledge, and computational thinking skills in higher education science classroom contexts.  相似文献

This article reports an investigation of the intuitive scientific ideas and understandings of 321 preservice elementary teacher education students enrolled in the 2nd year of a 3-year program. The sample completed a physical science concept challenge instrument by responding, in writing, to open-ended questions about the concepts of floating/sinking, the nature of matter, air pressure and its effects, and the balance beam. Subjects' responses and explanations were analyzed, and response categories established. The results reveal that the majority of subjects, with the exception of a high proportion of those who had a successful senior high school background in physics and chemistry, have misunderstandings in these basic concept areas. It is argued that teachers should have a sound conceptual knowledge base in order to implement effective problem-solving strategies in the elementary science classroom. The importance of teaching science in elementary schools is widely acknowledged, therefore, teacher educators must identify and implement more effective strategies for science instruction in preservice teacher education courses that will enable all students to construct scientifically accurate concept knowledge.  相似文献

This project focused on the goal of establishing a classroom model of motivation in which the source of student motivation is based on internal mechanisms or structures, along with the establishment of greater self-regulatory opportunities for students, and which results in greater student empowerment and motivation. One-hundred current elementary and secondary teachers and 100 university preservice teacher education students completed a 40-item Likert-type questionnaire that focused on four classroom dimensions of affirmation, rejection, student empowerment and teacher control. The results of this project suggested that, although veteran and preservice teachers agreed on the need for teacher control in the classroom, there was less agreement about their perceptions of the need to create a classroom environment of positive affirmation and student empowerment. Implications for future research and the need for creating an affirming, empowering, motivational classroom environment are discussed in light of the limitations for teachers and schools to encourage these constructs associated with recent federal legislative policies.  相似文献

The number of induction programs available to teachers is increasing rapidly, and by necessity these programs are designed to meet the needs of all teachers regardless of their preparation and academic background. This study examines the impact of a science‐focused induction program on secondary science teachers from different preparation programs. The 16 teachers were first‐year secondary science teachers who graduated the previous year from one of four different teacher‐preparation programs. All teachers were monitored during their first year of teaching, as they participated in the induction program, to understand their teaching beliefs, instructional practices, and experiences in the classroom. The analysis of data revealed that the preservice training of a science teacher influenced the type of support the teacher derived from the science‐focused induction program. Teachers from a preservice program with an extended student‐teaching experience and two science methods courses held beliefs aligned with student‐centered practices and implemented more reform‐based lessons than did other teachers during the year. This study reinforces the importance of induction programs for teachers and suggests that there is a need for specialized support programs for beginning science teachers. The study also provides specific suggestions for improving the preparation of secondary science teachers. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 963–985, 2006  相似文献

The practicum provides an opportunity for preservice teachers to apply knowledge and skills in actual classroom settings. Thus, it serves as a central component of virtually all teacher education programmes. This study focused the views of 16 preservice science teachers on their practicum experiences. Individual interviews were made to construct a picture of practicum as experienced by the preservice science teachers. Group seminar sessions, and written reflections were also utilised to confirm and support data from the interviews. The findings based on data gathered indicate that preservice science teachers were not exposed to environment that reflected their expectations toward learning outcomes. It is essential to provide conditions of a quality experience to preservice science teachers during their teacher education programmes in order to prepare preservice teachers to teach science effectively.  相似文献

Elementary preservice teachers at six universities engaged in a task that provided them opportunities to articulate their professional noticing within video representations, written decompositions, and animated approximations of practice. The preservice teachers’ written accounts indicated that a majority attended to students or student thinking; however, when asked to illustrate their noticing through animation, focus shifted to the classroom teacher. Findings indicate the extent to which preservice teachers articulated specific mathematics concepts within and across pedagogies of practice and highlight the critical importance for selecting and utilizing multiple types of tasks to better understand preservice teacher noticing. Implications for eliciting and supporting preservice teacher noticing are discussed.  相似文献

In this paper we present findings from a project that documented the development of preservice teachers’ beliefs and practices in delivering science instruction that considers issues of language and culture. Teacher candidates in the intervention group (n = 65) received a science methods course and teaching practicum experience that provided guidance in teaching science in culturally and linguistically responsive ways. Comparisons between a control group of preservice teachers (n = 45) and those involved in the intervention yielded stronger beliefs about the efficacy in promoting collaboration in science teaching than the intervention group. Observations of these preservice teachers during their teaching practicum revealed differences in favor of the intervention group in: (a) implementing science instruction that addressed the language and literacy involved in science; (b) using questions that elicited higher order thinking and; (c) providing scaffolds (e.g., purposeful feedback, probing student background knowledge) when confronting abstract scientific concepts. Implications for preservice teacher education are addressed.  相似文献

Given the dearth of high-quality curriculum materials aligned with the new standards (NGSS and CCSS) and low student persistence in STEM fields, we sought to develop and test a STEM curriculum that would improve student knowledge, interest, and emotions. A cluster randomized control trial was conducted to assess the impact of Speedometry, a two-unit STEM curriculum that uses familiar toy cars to explore math and science concepts. A total of 1,615 fourth-grade students across 48 classrooms and 17 schools in an urban district participated in the study. Using a 3-level multilevel model (students nested within teachers and schools) and controls for student and teacher characteristics, we found that Speedometry led to significant increases in student knowledge and positive emotions such as excitement. Speedometry also led to significant decreases in negative emotions such as boredom, frustration, and confusion. The curriculum was implemented with high fidelity as evidenced by classroom observations and teacher self-reports.  相似文献

This article describes an exploratory case study of secondary school physics teachers' conceptions of scientific evidence. The nature of teachers' conceptions of evidence was derived from an analysis of data collected from 1 preservice and 2 in‐service teachers. Each teacher responded to a series of research prompts in multiple interviews and handwritten tasks. In these research prompts, the teachers thought aloud while designing experiments and critically evaluating student‐collected data as presented in hypothetical classroom scenarios. Spoken and written data were recorded. The data set was coded and analyzed using standard qualitative analysis techniques. Data from this study suggest that, while contemplating the reliability and validity of hypothetical student‐generated scientific evidence, the teachers frequently intertwined conceptions of evidence with subject matter concepts centrally relevant to the hypothetical investigation. Data also indicate that the relationship between subject matter knowledge and conceptions of evidence was more pronounced for some conceptions of evidence than for others. Results suggest that a fuller study is warranted. Suggestions for future research include exploring such relationships in other physics content areas as well as other scientific disciplines. Implications for science teacher education suggest that science and science methods courses should encourage preservice teachers to engage in original scientific research, as well as participate in peer review and critique. © 2003 Wiley Periodicals, Inc.

There is a current national emphasis on science, technology, engineering, and mathematics (STEM). Additionally, many states are transitioning to the Next Generation Science Standards (NGSS), which encourage teachers to incorporate engineering in science classrooms as well as have their students learn science by doing science. Methods courses are also shifting to adequately prepare preservice science teachers in these areas. This study examines preservice science teachers’ pre- and post-ideal inquiry-based lesson plan scenarios before and after intervention in their Secondary Science Methods I and II courses. These preservice science teachers participated in a variety of opportunities to practice authentic science inquiry (ASI) pedagogical techniques as well as integrated STEM topics, with a particular emphasis on computer programming throughout their 80 h of Methods instruction. ASI is a type of inquiry where students learn science by conducting science research in a grade-appropriate manner. Thirty-eight preservice teachers’ scenarios were analyzed using a rubric from Spuck (2014) to determine the degree to which the ten components of ASI were included in scenarios pre- to post-instruction. Trends in ASI component inclusion are discussed. These findings indicate that preservice science teachers are proficient at writing inquiry-based lessons where they planned opportunities for their future students to collaborate, use scientific instrumentation, and collect and analyze data, but need additional support with developing student activities where students create testable questions, revise their question and methods, participate in peer review, and disseminate their results to their peers or the larger scientific community. Overall, the results suggest Methods instruction should reinforce preservice teachers’ focus on planning lessons which include opportunities for all ASI components. Interventions in the aforementioned areas of weak inclusion may be beneficial to preservice teachers.  相似文献

The premise that underlies the preservice‐teacher‐education programme at Monash University is the need to focus on the nature of learning (for example, Gunstone et al., 1993). One approach currently being used to enhance this process is the use of portfolios. The portfolio is an open‐ended task designed to explore teaching from many different vantage points. It is organised as a dynamic assessment task through which the student teachers work on developing their understanding of what it means to be a science teacher, and the teaching portfolio itself is a mixture of artefacts designed to help student teachers demonstrate this to others. This paper reports on the effectiveness and value of portfolios in helping preservice teachers learn about learning and teaching.  相似文献

Research and design activities are important focus points in international policies for secondary Science, Technology, Engineering and Mathematics (STEM) education. It is up to school teachers to implement and supervise these activities in the STEM classroom. However, not much is known about the attitudes teachers hold towards supervising research projects or design projects. In this study, a questionnaire to measure teacher attitudes towards supervising research activities and design activities in secondary school was completed by 130 Dutch teachers who taught the relatively new Dutch STEM subjects O&O (research and design) and NLT (nature, life, and technology). These integrated STEM subjects are project and context based and are taught in a limited number of schools. Important differences between these integrated STEM subjects are their student and teacher populations: NLT is taught in grades 10–12 by teachers with a qualification in a science subject, while O&O is taught in grades 7–12 and can be given by any teacher in secondary school. The results showed that on average, both O&O and NLT teachers had high self-efficacy scores on supervising research and design projects even when they had received no special education in doing so. Furthermore, the teachers in general viewed supervising research projects as a more relevant activity than supervising design. Since research and design activities are becoming more important in (inter)national curriculum standards, STEM teacher education and subsequent professional development should not only familiarize teachers with supervising research projects, but with design projects as well.

This qualitative, multi-case study explored the use of science-content music for teaching and learning in six middle school science classrooms. The researcher sought to understand how teachers made use of content-rich songs for teaching science, how they impacted student engagement and learning, and what the experiences of these teachers and students suggested about using songs for middle school classroom science instruction. Data gathered included three teacher interviews, one classroom observation and a student focus-group discussion from each of six cases. The data from each unit of analysis were examined independently and then synthesized in a multi-case analysis, resulting in a number of merged findings, or assertions, about the experience. The results of this study indicated that teachers used content-rich music to enhance student understanding of concepts in science by developing content-based vocabulary, providing students with alternative examples and explanations of concepts, and as a sense-making experience to help build conceptual understanding. The use of science-content songs engaged students by providing both situational and personal interest, and provided a mnemonic device for remembering key concepts in science. The use of songs has relevance from a constructivist approach as they were used to help students build meaning; from a socio-cultural perspective in terms of student engagement; and from a cognitive viewpoint in that in these cases they helped students make connections in learning. The results of this research have implications for science teachers and the science education community in developing new instructional strategies for the middle school science classroom.  相似文献

This writing describes a literacy project between preservice teachers enrolled in a small university in Montana and an inner city school classroom in Kansas. It shows how the preservice teachers and children negotiate meaning at the beginning of the project as well as what the preservice teachers were learning from the children and from their teacher, Scott. Twenty-three third grade children exchanged letters, cards, drawings, autobiographies, and writing about shared literature with 24 preservice teachers for 10 weeks. Scott, the third grade teacher who assisted with the project, was a former student in Rita’s university language arts classroom and was strongly committed to demonstrating to preservice teachers the rewards of teaching in an inner city classroom ... particularly those coming from communities where people of color or linguistic diversity were few. Through shared written responses and the negotiation of meaning between two age groups, this project opened pathways for greater insight into the cultures and lives of children that the university students might otherwise not have known. It also provided myriad glimpses into the lives of real children, each with his or her own interests, life experiences, and expressive modalities thus shaping the perceptions of the preservice teachers about their role as teacher in supporting and responding to the individual strengths of each child.  相似文献

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  相似文献

The purposes of this study were to develop instruments to assess the nature of student-teacher relations and classroom activities, and the personal adjustment of preservice science teachers in two concurrent programs and to see if the two groups differed significantly in the three areas measured by the Checklist for Assessment of Science Teachers (CAST). The CAST was completed by university supervisors, cooperating teachers, and classroom pupils in terms of 92 secondary student teachers at the completion of three student teaching quarters. Multivariate analysis of variance was used to detect differences between treatment groups. The major differences between the two groups of science student teachers were the types of classroom activities used and the nature of their student-teacher (teacher-pupil) relations.  相似文献

Surrounding the national emphasis on improving STEM education, effective STEM educators are required. Connected, yet often overlooked, is the need for effective preservice STEM teaching instruction for incoming educators. At a basic level, preservice STEM teacher education should include STEM content, pedagogy, and conceptualization. However, the literature suggests no leading conception of STEM education, and little is known about how preservice STEM teachers are conceptualizing STEM education. In order to explore preservice STEM teacher conceptions of STEM education, preservice teachers at a large, Midwestern research university were given an open-ended survey eliciting both textual and visual responses. Here, we report and discuss the results of employing this instrument in relation with the current STEM conceptualization literature.  相似文献
