Inadequate science knowledge of preservice teachers enrolled in science methods courses not only limits their mastery of effective teaching practices, but also may foster negative attitudes toward science teaching. This study investigated the influence of science knowledge upon attitudes toward science teaching in a one-semester elementary science methods course by embedding a videodisk-based instructional component to remediate knowledge deficiencies. Preservice teachers in the experimental group first learned core concepts in physical and earth science through a series of 24 interactive videodisk lessons and then used the concepts as a foundation for preparing and presenting model science lessons. Results showed that the experimental group overcame their initial knowledge deficiencies by mastering the core concepts presented (mean proportion correct on mastery test = 0.91), with multivariate covariance analysis confirming that the experimentals gain in science knowledge was significantly greater than comparable controls in the parallel science methods sections. Additionally, as a result of mastering the core concepts underlying earth science, preservice teachers using the videodisk instruction also displayed significantly greater confidence in their understanding of science knowledge and more positive attitudes toward science teaching at the elementary levels. Implications for improving elementary science teaching through preservice and in-service training are discussed.  相似文献

Analogies have been argued to be central in the process of establishing conceptual growth, making overt connections and carryover into an intended cognitive domain, and providing a generative venue for developing conceptual understanding inherent in constructivist learning. However, students' specific uses of analogies for constructing arguments are not well understood. Specifically, the results of preservice teachers' knowledge gains are not widely studied. Although we would hope that engaging preservice science teachers in exemplary lessons would assist them in using and generating analogies more expertly, it is not clear whether or how such curricula would affect their learning or teaching. This study presents an existence proof of how preservice science teachers used analogies embedded in their course materials Physics by Inquiry. This fine‐grained analysis of small group discourse revealed three distinct roles of analogies including the development of: (a) cognitive process skills, (b) scientific conceptual understanding, and (c) social contexts for problem solving. Results suggest that preservice teachers tend to overgeneralize the analogies inserted by curriculum materials, map irrelevant features of analogies into collaborative problem solving, and generate personal analogies, which counter scientific concept development. Although the authors agree with the importance of collaborative problem solving and the insertion of analogies for preservice teachers' conceptual development, we believe much more needs to be understood before teachers can be expected to construct and sustain effective learning environments that rely on using analogies expertly. Implications for teacher preparation are also discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 443–463, 2003  相似文献

Teachers are ideally placed to identify and refer pupils who self-injure, but are often unaware when pupils self-injure or unsure how to respond. The aims of this study were to explore and compare pre-service and in-service teachers’ knowledge and attitudes towards self-injury, and their confidence responding to pupils who self-injure. Pre-service teachers (n = 267) and in-service teachers (n = 261) completed self-report questionnaires. Prior education regarding self-injury was positively related to knowledge and confidence, while pre-service teachers were more confident than in-service teachers in their ability to cope with legal and school regulations. Thematic analysis of open-ended questions indicated that although pre- and in-service teachers are concerned about pupils who self-injure and are willing to help these students, they feel ill-informed about self-injury and requested school policies and additional education regarding the behaviour. Results have implications for educational programmes that prepare pre- and in-service teachers to identify and respond to pupils who self-injure.  相似文献

Quality mentoring is fundamental to preservice teacher education because of its potential to help student and novice teachers develop the academic and pedagogical knowledge and skills germane to successful induction into the profession. This study focused on Jordanian preservice primary teachers' perceptions of their mentoring experiences as these pertain to science teaching. The Mentoring for Effective Primary Science Teaching instrument was administered to 147 senior preservice primary teachers in a university in Jordan. The results indicated that the greater majority of participants did not experience effective mentoring toward creating a supportive and reflexive environment that would bolster their confidence in teaching science; further their understanding of primary science curriculum, and associated aims and school policies; help with developing their pedagogical knowledge; and/or furnish them with specific and targeted feedback and guidance to help improve their science teaching. Substantially more participants indicated that their mentors modeled what they perceived to be effective science teaching. The study argues for the need for science-specific mentoring for preservice primary teachers, and suggests a possible pathway for achieving such a model starting with those in-service primary teachers—much like those identified by participants in the present study—who are already effective in their science teaching.  相似文献

Drawn from the norms and rules of their fields, scientists use variety of practices, such as asking questions and arguing based on evidence, to engage in research that will contribute to our understanding of Earth and beyond. In this study, we explore how preservice teachers' learn to teach scientific practices while teaching plate tectonic theory. In particular, our aim is to observe which scientific practices preservice teachers use while teaching an earth science unit, how do they integrate these practices into their lessons, and what challenges do they face during their first time teaching of an earth science content area integrated with scientific practices. The study is designed as a qualitative, exploratory case study of seven preservice teachers while they were learning to teach plate tectonic theory to a group of middle school students. The data were driven from the video records and artifacts of the preservice teachers' learning and teaching processes as well as written reflections on the teaching. Intertextual discourse analysis was used to understand what scientific practices preservice teachers choose to integrate into their teaching experience. Our results showed that preservice teachers chose to focus on four aspects of scientific practices: (1) employing historical understanding of how the theory emerged, (2) encouraging the use of evidence to build up a theory, (3) observation and interpretation of data maps, and (4) collaborative practices in making up the theory. For each of these practices, we also looked at the common challenges faced by preservice teachers by using constant comparative analysis. We observed the practices that preservice teachers decided to use and the challenges they faced, which were determined by what might have come as in their personal history as learners. Therefore, in order to strengthen preservice teachers' background, college courses should be arranged to teach important scientific ideas through scientific practices. In addition, such practices should also reflect the authentic practices of earth scientists such as use of historical record and differentiating observation versus interpretation.  相似文献

Global climate change is receiving increasing attention as a classroom topic. At the same time, research has shown that individuals have strong emotions about the topic. Emotions about controversial topics and individuals' dispositions toward knowledge have been shown to influence judgments about these topics. This study examined the relationships among preservice elementary and in-service secondary science teachers' emotions about and plausibility perceptions of climate change, background knowledge of weather and climate distinctions (a principle related to understanding climate change), and dispositions toward knowledge. Teachers' topic emotions (anger and hopelessness) were significant predictors of plausibility perceptions, with more anger associated with lesser plausibility and greater hopelessness associated with higher plausibility. Decisiveness—an urgent desire to reach closure—was also significantly related to plausibility perceptions with greater decisiveness associated with reduced plausibility perceptions. In-service secondary teachers who do not currently teach about climate change exhibited greater anger and decisiveness than preservice elementary teachers and in-service secondary teachers who do teach about climate change. Implications for climate literacy education are discussed.  相似文献

ABSTRACT

The following exploratory study examines the effects of a Harry Potter–inspired “border crossing” analogy (HPBCA) on preservice teachers' (n = 25) Teaching English to Speakers of Other Languages (TESOL) content knowledge and disposition toward English language learners (ELLs). The analogy capitalizes on the prior and shared background knowledge many preservice teachers have of J. K. Rowling's Harry Potter novels, the related films, and discourses that surround the Harry Potter phenomenon. Study results suggest mild agreement among participants of the perceived positive impact of the HPBCA on their TESOL content knowledge, although a slightly less than neutral response toward the perceived impact on their disposition toward ELLs. The results hold implications for the pedagogical use of analogy in teacher education beyond mathematics and science, as well as the role of prior/shared knowledge in teaching and learning.  相似文献

Pre‐service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre‐service teachers often enter teacher education courses with pre‐conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty‐one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience‐based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 497–523, 2008  相似文献

Arizona is one of six states leading the nation in English language learner (ELL) student enrollments and requiring all teachers to complete coursework in methods of teaching ELLs. This policy requirement has impacted teacher preparation programs and the field of teacher education as a whole. As such, there is a growing need to identify and evaluate factors that contribute to ELL teacher readiness. This exploratory survey study examines teacher readiness to work with ELLs in comprehensive public high schools in Arizona. This study was conducted using a survey instrument administered to in-service teachers (n?=?444). Correlation analyses indicate that there is a strong association between preservice preparation, preservice exposure to ELLs, and the feeling of readiness to serve ELLs. The findings make a strong case for further examination of preservice teacher preparation programs, in-service professional development, and their relationship to teacher readiness.  相似文献

This study utilized responses from Taiwanese preservice elementary teachers to describe and analyze their conceptions about the assessment of science learning and the extent that these conceptions were coherent with their views of learning science. A methodological framework of phenomenography was used for the study. The results revealed that the preservice teachers' mode of assessment was coherent with a traditional view of learning but their performance mode of assessment was not well developed. Improving preservice teachers' conception of assessment requires clarifying and reconstructing their conceptions of and coherence between assessment, curriculum, pedagogy, and learning.  相似文献

This study explored the effects of community-based service-learning (CBSL), supplemented with discussions and activities about diversity, on the self-efficacy beliefs of preservice elementary teachers regarding equitable science teaching and learning for diverse student groups. The study was conducted with 81 preservice teachers enrolled in four sections of an elementary science methods course over a semester. Employing a mixed-methods research design, data were collected using pretests–posttests with the study sample and semistructured interviews with a subsample. The results support the value of preservice teachers engaging in CBSL experiences, supplemented with discussions and activities about diversity, as a way to improve their self-efficacy beliefs regarding equitable science teaching and learning of all students.  相似文献

Part of the work of teaching elementary science involves evaluating elementary students' work. Depending on the nature of the student work, this task can be straightforward. However, evaluating elementary students' representations of their science learning in the form of scientific models can pose significant challenges for elementary teachers. To address some of these challenges, we incorporated a modeling-based elementary science unit in our elementary science teaching methods course to support preservice teachers in gaining knowledge about and experience in evaluating students' scientific models. In this study, we investigate the approaches and criteria preservice elementary teachers use to evaluate elementary student-generated scientific models. Our findings suggest that with instruction, preservice elementary teachers can adopt criterion-based approaches to evaluating students' scientific models. Additionally, preservice teachers make gains in their self-efficacy for evaluating elementary students' scientific models. Taken together, these findings indicate that preservice teachers can begin to develop aspects of pedagogical content knowledge for scientific modeling.  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

This study examined changes in personal science teaching self-efficacy (PSTE), outcome expectancy (STOE), and science conceptual understanding and relationships among these in preservice teachers. Seventy preservice teachers enrolled in science teaching methods courses participated in this study. PSTE, STOE, and science conceptual understanding increased significantly during participation in the course. The study established that novice learners with minimal prior knowledge could not be expected to understand and employ core concepts in their learning schema without extensive guidance. The relationship between science learning confidence and science teaching confidence has not been theoretically delineated in the area of science teacher education. Findings suggest there may be important connections between the 2 for preservice teachers that would be fruitful areas for future research.  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

Final year preservice teachers' perceptions of their mentoring in primary science teaching were gathered through surveys from three separate studies. The three studies (n = 59, n = 331, n = 60) provided an indication of the degree of mentoring preservice teachers perceived they received with mentoring practices linked to Pedagogical Knowledge. This research argues that mentors require pedagogical knowledge of primary science for guiding mentees with planning, timetabling, preparation, implementation, classroom management strategies, teaching strategies, science teaching knowledge, questioning skills, problem-solving strategies, assessment techniques, and developing viewpoints on science pedagogy. The key study findings (n = 331, from nine Australian universities involved in primary teacher education) indicated that 55% or more mentees had not received Pedagogical Knowledge for primary science teaching in each of the associated mentoring practices (mean score range: 2.60–2.91, standard deviation range: 1.10–1.32). The study concludes that mentors require further professional development to ensure that preservice teachers (mentees) receive adequate pedagogical knowledge for teaching primary science, which will involve significant collaboration between universities and schools.  相似文献

The purpose of this study was to explore child care teachers' perceptions of their initial preservice and in-service training experiences. Eighteen child care teachers working in six for-profit centers were interviewed. Based on the participants' responses, the findings are organized in two themes. First, because many of them entered the field without significant training and education, received little or no preservice training, and then participated in minimal amounts of in-service training, these teachers described their experience as being “thrown into the classroom.” Second, due to this lack of training, the teachers discussed the ways in which they were “figuring out how to do it” in terms of using their own natural abilities, learning by experience, and learning from other teachers by watching and asking questions. The findings of this study have implications for the field in terms of designing and structuring professional development opportunities for child care teachers to better meet their needs within particular contexts.  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
