Abstract

How to prepare teachers to work with culturally and linguistically diverse students and families is an important aspect of teacher education as classrooms continue to diversify. Community-based approaches to teaching offer promising strategies for addressing this need. This article offers one example of an English as a Second Language literacy methods course that built preservice teachers’ understanding of and experiences with diverse language communities. Tara Yosso’s Community Cultural Wealth (CCW) framework provided a theoretical lens for the course and guided the preservice teachers’ teaching and reflections. The preservice teachers engaged in various activities that included literacy teaching, visiting places in their students’ communities, learning their students’ language, and creating narrative videos with the students and their families. The findings from this course show how the CCW framework can be a constructive method for identifying community assets when combined with a variety of activities for preservice teachers to engage with students and their families.  相似文献

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.  相似文献

Grounded in Hallidayan perspectives on academic language, we report on our development of an educative science assessment as one component of the language-rich inquiry science for English-language learners teacher professional learning project for middle school science teachers. The project emphasizes the role of content-area writing to support teachers in diagnosing their students’ emergent understandings of science inquiry practices, science content knowledge, and the academic language of science, with a particular focus on the needs of English-language learners. In our current school policy context, writing for meaningful purposes has received decreased attention as teachers struggle to cover large numbers of discrete content standards. Additionally, high-stakes assessments presented in multiple-choice format have become the definitive measure of student science learning, further de-emphasizing the value of academic writing for developing and expressing understanding. To counter these trends, we examine the implementation of educative assessment materials—writing-rich assessments designed to support teachers’ instructional decision making. We report on the qualities of our educative assessment that supported teachers in diagnosing their students’ emergent understandings, and how teacher–researcher collaborative scoring sessions and interpretation of assessment results led to changes in teachers’ instructional decision making to better support students in expressing their scientific understandings. We conclude with implications of this work for theory, research, and practice.  相似文献

Science vocabulary knowledge plays a role in understanding science concepts, and science knowledge is measured in part by correct use of science vocabulary (Lee et al. in J Res Sci Teach 32(8):797–816, 1995). Elementary school students have growing vocabularies and many are learning English as a secondary language or depend on schools to learn academic English. Teachers must have a clear understanding of science vocabulary in order to communicate and evaluate these understandings with students. The present study measured preservice teachers’ vocabulary knowledge during a science methods course and documented their use of science vocabulary during peer teaching. The data indicate that the course positively impacted the preservice teachers’ knowledge of select elementary science vocabulary; however, use of science terms was inconsistent in microteaching lessons. Recommendations include providing multiple vocabulary instruction strategies in teacher preparation.  相似文献

Teachers need an understanding of the nature of science (NOS) to enable them to incorporate NOS into their teaching of science. The current study examines the usefulness of a strategy for challenging or changing teachers’ understandings of NOS. The teachers who participated in this study were 10 initial teacher education chemistry students and six experienced teachers from secondary and primary schools who were introduced to an explicit and reflective activity, a dramatic reading about a historical scientific development. Concept maps were used before and after the activity to assess teachers’ knowledge of NOS. The participants also took part in a focus group interview to establish whether they perceived the activity as useful in developing their own understanding of NOS. Initial analysis led us to ask another group, comprising seven initial teacher education chemistry students, to take part in a modified study. These participants not only completed the same tasks as the previous participants but also completed a written reflection commenting on whether the activity and focus group discussion enhanced their understanding of NOS. Both Lederman et al.’s (Journal of Research in Science Teaching, 39(6), 497–521, 2002) concepts of NOS and notions of “naive” and “informed” understandings of NOS and Hay’s (Studies in Higher Education, 32(1), 39–57, 2007) notions of “surface” and “deep” learning were used as frameworks to examine the participants’ specific understandings of NOS and the depth of their learning. The ways in which participants’ understandings of NOS were broadened or changed by taking part in the dramatic reading are presented. The impact of the data-gathering tools on the participants’ professional learning is also discussed.  相似文献

The intent of the present study is to describe preservice elementary teachers’ understanding of science and how certain contextual variables contribute to this understanding.

Eighty students in three sections of an elementary science methods course participated in the study by completing a questionnaire. Six questions dealt with knowledge of science, theories and evolution. In addition, a 21‐item rating scale covering various aspects of science and science teaching was included.

The major theme arising out of the data is how beliefs affect preservice teachers’ understandings of science. The anthropocentricity in the subjects’ definitions and purposes of science, theories and evolution is the most explicit and pervasive of the beliefs influencing the conceptualizations of science. The often vague and misinformed definitions of theories add a further dimension of how science is perceived. When evolution is introduced, both the anthropocentric view of science and the misunderstood notion of theory come together to confound the subjects’ understanding. When asked about the teaching of evolution, the subjects’ confusion concerning the nature of science becomes strikingly evident.

ABSTRACT

Graduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted.  相似文献

This study aimed to assess the influence of a philosophy of science (POS) course on science teachers’ views of nature of science (NOS), perceptions of teaching about NOS, and instructional planning related to NOS. Participants were 56 undergraduate and graduate preservice secondary science teachers enrolled in a two science‐methods course sequence, in which participants received explicit, reflective NOS instruction. Ten of these participants were also enrolled in a graduate survey POS course. The Views of Nature of Science Questionnaire — Form C coupled with individual interviews was used to assess participants’ NOS views at the beginning and conclusion of the study. Participants’ lesson plans and NOS‐specific reflection papers were analysed to assess the impact of the POS course on their instructional planning related to, and perceptions of teaching about, NOS. Results indicated that, compared with participants enrolled in the methods courses, the POS course participants developed deeper, more coherent understandings of NOS. Substantially more of these latter participants planned explicit instructional sequences to teach about NOS. Additionally, the POS course participants’ discourse regarding NOS progressed from a preoccupation with the technical, to a concern with the practical, and, finally, to a focus on the emancipatory. Their views of teaching about NOS in their future classrooms went beyond the customary discourse of whether pre‐college students should or could be taught about NOS, to contemplating changes they needed to bring about in their own teaching behaviour and language to achieve consistency with their newly acquired NOS understandings.  相似文献

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.  相似文献

Teach For America (TFA), a widespread and well-known route into the teaching profession, frequently partners with university-based education programs to prepare and certify its corps members. However, university-based teacher education programs frequently emphasize very different understandings of socially just education and priorities for training teachers from those of TFA. Accordingly, science teachers trained through TFA-university partnerships encounter conflicting understandings of science education, justice, and urban communities as they are introduced to teaching practice. In this ethnographic case study we explored the experiences and reactions of a cohort of TFA corps members in a science methods course as they engaged with TFA’s perspective focused primarily on enhancing students’ social mobility and the methods course emphasizing democratic equality through scientific engagement. The study considers intersections between TFA’s approach to teacher preparation and sociocultural perspectives on equitable science teaching. The study also lends insight into the contradictions and challenges through which TFA science teachers develop understandings about their role as science teachers, purposes and goals of science education, and identities of the students and communities they serve.  相似文献

This paper explores the nature of prospective teachers’ noticing of students’ understanding as they analyze and discuss middle school students’ understandings of trapezoids in micro-case videos in the context of geometry. In this exploratory study, the data were obtained from eight prospective middle school mathematics teachers through individual video analysis, reflection papers, and group discussions. The results indicated that the use of purposeful micro-case video designs based on prospective teachers’ background knowledge of quadrilaterals allowed them to be productive in video analyses and discussions. In individual video analyses, prospective teachers attended to various mathematical elements to identify students’ responses but did not always use them to make interpretations of each student’s understanding of trapezoid. In the group discussions of the micro-case videos, in contrast, prospective teachers could provide alternative interpretations of students’ understanding by identifying links between the mathematical elements in students’ responses and the characteristics of students’ understandings. In the group discussions, they provided more detailed and specific instructional actions to support each student’s understanding of trapezoid than their individual video analyses. This study suggests practical implications for teacher education programs on how to use video cases (e.g., firstly, working individually and then having group discussions about the videos) to explore prospective teachers’ professional noticing skills. Considering prospective teachers’ background knowledge of related mathematical contents, this study can also inspire future studies on how to design effective videos about students’ mathematical understanding.

Sixteen male student primary teachers on a primary Initial Teacher Education course were interviewed and their understanding of 'care' explored. Analysis of the data suggests that male student primary teachers have specific gendered understandings of 'care'. Teacher educators need to take account of this in primary Initial Teacher Education courses and to provide students with opportunities to reflect on their understanding of 'care' in relation to their work as primary teachers, and the part gender plays in shaping that understanding.  相似文献

The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012–2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers’ discussions about science in the classroom, since it is teachers’ understanding of NOS reflected in these discussions that will have a vital impact on students’ learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers’ active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers’ instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.  相似文献

Background: There has been an increasing emphasis on empowering pre-service and in-service science teachers to attend student reasoning and use formative assessments to guide student learning in recent years. Purpose: The purpose of this study was to explore pre-service science teachers’ pedagogical capacity for formative assessment. Sample: This study took place in Turkey. The participants include 53 pre-service science teachers in their final year of schooling. All but two of the participants are female. Design and methods: We used a mixed-methods methodology in pursing this inquiry. Participants analyzed 28 responses to seven two-tiered questions given by four students of different ability levels. We explored their ability to identify the strengths and weaknesses in students’ answers. We paid particular attention to the things that the pre-service science teachers noticed in students’ explanations, the types of inferences they made about students’ conceptual understanding, and the affordances of pedagogical decisions they made. Results: The results show that the majority of participants made an evaluative judgment (i.e. the answer is correct or incorrect) in their analyses of students’ answers. Similarly, the majority of the participants recognized the type of mistake that the students made. However, they failed to successfully elaborate on fallacies, limitations, or strengths in student reasoning. We also asked the participants to make pedagogical decisions related to what needs to be done next in order to help the students to achieve academic objectives. Results show that 8% of the recommended instructional strategies were of no affordance, 64% of low-affordance, and 28% were of high affordance in terms of helping students achieve the academic objectives. Conclusion: If our goal is to improve pre-service science teachers’ noticing skills, and the affordance of feedback that they provide, engaging them in activities that asks them to attend to students’ ideas and reasoning may be useful.  相似文献

Abstract

The study examined the integration of science and mathematics methods courses and preservice teachers’ understanding of constructivism. The participants were 50 preservice teachers who were enrolled in early childhood education mathematics and science methods courses, and an early childhood practicum. The two methods courses were integrated and the instructors adopted a collaborative approach, including common syllabi, texts, assignments, and teaching strategies. The preservice teachers completed e‐journal reflection that were subsequently coded and analyzed. The findings suggested that the instructional approach enabled students to develop and refine their understanding of constructivism. © 2005 Elsevier Inc. All rights reserved.  相似文献

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of science strongly relates to a student's science capital. This paper reports on findings from the pilot year of a one-year professional development (PD) programme designed to work with secondary-school teachers to build students’ science capital. The PD programme introduced teachers to the nature and importance of science capital and thereafter supported them to develop ways of implementing science capital-building pedagogy in their practice. The data comprise interviews with the participating teachers (n?=?10), observations of classroom practices and analyses of the teachers’ accounts of their practice. Our findings suggest that teachers found the concept of science capital to be compelling and to resonate with their own intuitive understandings and experiences. However, the ways in which the concept was operationalised in terms of the implementation of pedagogical practices varied. The difficulties inherent in the operationalisation are examined and recommendations for future work with teachers around the concept of science capital are developed.  相似文献

ABSTRACT

To explore the affordances of learning progressions (LP) in support of teachers’ formal and informal formative assessment (FFA and IFA) practices, we conducted a case study with a fine-grain-sized energy LP. The study first theorises an LP-based formative assessment model, which proposes the use of LPs in clarifying learning objectives, eliciting and interpreting students’ understanding, and acting in instruction. Then, we examine multiple iterations of two high-school teachers’ lesson plans and their enactment of the lessons to identify the instructional adjustments teachers made as part of the LP-based FFA and IFA after professional training. We found that both teachers refined the learning objectives and activities and most of their adjustments promoted students’ learning progression; their adjustments have an interdependency between objectives and activities. Both made more adjustments in the IFA than in the FFA, but the alignment with the LP was higher in FFA than in IFA. Contrary to the researchers’ expectations, both teachers perceived the LP as a content structure. However, in practice, both employed it as a reference to interpret students’ responses by comparing these responses against their own expectations. The teachers also reported collecting assessment information during teacher-student interactive activities and using this material to infer the level of students’ understanding in order to decide on the next instructional activities. Both teachers reported that the process of directly engaging with the LP formatively resulted in their having a much more nuanced sense of students’ understanding when they revisited and altered the sequence of the learning activities.  相似文献

The aim of this paper is not to bury practical work in school science but to (once again) reconsider it. We draw on three main areas of discussion: accounts of science and ‘school science work'; teachers and others’ views of the nature of science; and our own data on teachers’ reactions to ‘critical incidents’ and practicals which go wrong. We use this as a basis for re‐thinking the role of practicals. An account of practical work is suggested which has as its main feature diversity rather than a single model or template. Within this diversity we believe that teachers should be open and honest with pupils about which type of practical work they are doing and why. We advocate that students should be made aware of the different kinds of practical work they do and the purposes of this practical work. In short, teachers should explain to students what type of practical work they are doing and why. Our second message is that teachers’ views about the nature of science both inform and are informed by their classroom practices and experiences‐‐especially during lab‐work. To encourage, promote and support critical reflection of these classroom practices and experiences is therefore a vital part of teacher professional development; this in time will promote science curriculum development.  相似文献
