ABSTRACTThe aim of this study is to provide an understanding of context-based inquiry teaching within a humanistic perspective on science education by studying pre-service teachers’ beliefs about inquiry and their implementations of inquiry in their context-based teaching sequences. Therefore, five pre-service teachers enrolled in a university undergraduate course called ‘Inquiry-based chemistry education II’ (5 ECTS) were involved in an empirical case study. The pre-service teachers’ implementations of inquiry were studied from their reports on self-designed context-based inquiry teaching sequences for students age 13–15, and their beliefs by interviewing them after the course. The results indicate that the most frequent aspects of inquiry, which were implemented, were that inquiry (i) includes a context, (ii) is a way to act, (iii) is a way to think, and (iv) includes source/information evaluation and argumentation. The pre-service teachers’ beliefs about inquiry were shown to reflect manifold aspects of inquiry, such as the difficulty in explaining it. However, this difficulty in encapsulating inquiry into a clear-cut definition is not necessarily an impediment to inquiry-based teaching. Furthermore, inquiry is inherently context-bound, and context-based teaching requires extra-situational knowledge from the context and not only declarative knowledge from science. This should be considered to support effective professional development. 相似文献

In this study, we looked at the impact of our specially designed inquiry-based science courses for pre-service elementary teachers on their science content knowledge as measured by a high-stakes state certification test for elementary education. We conducted a pre/post-analysis of the certification test scores of 1,003 pre-service teachers. Cohort 1 consisted of 424 students who took the test prior to implementation of our reformed science courses. Cohort 2 consisted of 579 students taking the test after complete implementation. We examined overall test scores, science subscores, total science credits, age, and science transfer credits. We found that the overall test score dropped significantly from cohort 1 to cohort 2, but the science subscores remained unchanged. Our results showed that students who took all 3 of the science content courses vs. none scored significantly higher on the science portion, non-traditional students (older than 25) scored similarly to traditional-aged students, and there was a negative correlation with the number of science courses transferred. Of importance is the fact that students who took the minimal number of science courses and are less interested in science passed the science portion at the same rate (over 90%) as science majors and minors. We conclude that our pre-service elementary teachers can and do learn science content using inquiry as recommended by the National Science Education Standards (NRC, 1996). 相似文献

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed. 相似文献

This paper reports on the reality of classroom‐based inquiry learning in science, from the perspectives of high school students and their teachers, under a national curriculum attempting to encourage authentic scientific inquiry (as practiced by scientists). A multiple case study approach was taken, utilising qualitative research methods of unobtrusive observation, semi‐structured interviews and document analysis. The findings showed purposeful and focused learning occurring, but students were acquiring a narrow view of scientific inquiry where the thinking was characteristically rote and low‐level. The nature of this learning was strongly influenced by curriculum decisions made by classroom teachers and science departments in response to the assessment requirements of a high stakes national qualification. As a consequence of these decisions, students experienced structured teaching programmes in which they were exposed to programme content that limited the range of methods that scientists use to fair testing and to pedagogies that were substantially didactic in nature. In addition, the use of planning templates and exemplar assessment schedules tended to reduce student learning about experimental design to an exercise in “following the rules” as they engaged in closed rather than open investigations. Thus, the resulting student learning was mechanistic and superficial rather than creative and critical, counter to the aims of the national curriculum policy that is intent on promoting students’ knowledge and capabilities in authentic scientific inquiry. 相似文献

The development of new courses is strengthened by assessment and a response to the assessment. Two new science methods courses for elementary and secondary preservice teachers were developed, fostered by the Great Salt Lake Project. The preservice teachers designed and performed research projects that they then converted into inquiry-based teaching units. The professors applied a 3-layer assessment scheme to evaluate the courses and the preservice teachers based on changes in student attitudes, student-generated curricula, and internal course evaluations. Each type of assessment effectively informed the reform process, and strengths and weaknesses of the courses were revealed. Strengths of the courses included students learning to see science as a process and comprehending inquiry as a pedagogical approach. Weaknesses observed included a lack of understanding in three areas: the role of assessment, the need to address cultural issues, and the significance of scientific literacy. 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

In the context of the emphasis on inquiry teaching in science education, this study looks into how pre-service elementary
teachers understand and practise science inquiry teaching during field experience. By examining inquiry lesson preparation,
practice, and reflections of pre-service elementary teachers, we attempt to understand the difficulties they encounter and
what could result from those difficulties in their practice. A total of 16 seniors (fourth-year students) in an elementary
teacher education program participated in this study. In our findings, we highlight three difficulties ‘on the lesson’ that are related to teaching practices that were missing in the classrooms: (1) developing children’s own ideas and curiosity,
(2) guiding children in designing valid experiments for their hypotheses, (3) scaffolding children’s data interpretation and
discussion and another three difficulties ‘under the lesson’ that are related to problems with the pre-service teachers’ conceptualization of the task: (4) tension between guided and
open inquiry, (5) incomplete understanding of hypothesis, and (6) lack of confidence in science content knowledge. Based on
these findings, we discuss how these difficulties are complexly related in the pre-service teachers’ understandings and action.
Several suggestions for science teacher education for inquiry teaching, especially hypothesis-based inquiry teaching, are
then explored. 相似文献

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous research. Using a two‐level hierarchical linear model, we analyze year‐end knowledge integration performance of 4,513 students taught by 40 teachers across five states. Results indicate that students of teachers who value inquiry teaching strategies have significantly higher levels of knowledge integration understanding than those of teachers who believe in traditional teaching methods. In addition, workshop attendance and having a partner teacher teaching the same unit in the same school also have a positive impact on students' knowledge integration levels. The results underscore the importance of professional development and collegial support in enhancing student success in inquiry science. © 2009 Wiley Periodicals, Inc.

Pre-service teachers are taught that the funds of knowledge their students bring to school provide intellectual resources to be engaged through productive pedagogies. Teacher education may assist and/or hinder World English Speaking (WES) pre-service teachers in gaining access to the teaching profession by doing likewise. The interpretative case study presented in this paper involves exploring possibilities for teacher education programs to make transnational knowledge connections through WES pre-service teachers. Evidence from interviews with WES pre-service teachers and their Anglophone teacher educators are analysed to elaborate issues confronting teacher education programs involving World English Speakers. The findings indicate that teamwork which is constructed to privilege the knowledge of Anglophone pre-service teachers over their WES peers is questionable. Further, WES pre-service teachers are not only structurally disadvantaged by teamwork practices that privilege local knowledge, they are also challenged by teacher educators’ assessment procedures. The pressures created on teacher educators’ workloads, may lead to ‘lean and mean’ assessment procedures which serve to contain excessive demands on their labour, but do not necessarily resolve the dilemma of how to use assessment practices that minimise WES pre-service teachers’ learning. 相似文献

This article examines the influence of a practicum teaching experience on two pre-service science teachers. The research is focused on examining a practicum in a secondary science department that actively promotes the teaching and learning of science as inquiry. We investigated the process through which the pre-service science teachers integrated their practical knowledge, and examined this in the context of the quantified reformed instruction they enacted. Using a mixed methods design, we have quantified these pre-service science teachers’ practice using the Reformed Teaching Observation Protocol (Piburn et al. 2000), in concert with a narrative methodology drawn from in-depth interviews. Our analysis of the data indicates two important conclusions. The first is the importance of a consistently reformed image of science education being presented and practiced by both science teacher educators and cooperating teachers. The second is the recognition that a consistently reformed image may not be sufficient, of itself, to challenge pre-service teachers’ views of science education. Pre-service teachers appear to be heavily influenced by their biographies and own science education. Consequently, it appears the extent to which a pre-service teacher identifies problems of teaching and learning, and then works toward possible resolution, influences their progress in shaping reformed views of science education. 相似文献

Characteristics of Pre-Service Teachers’ Online Discourse: The Study of Local Streams 总被引：2，自引：2，他引：0

This study describes the characteristics of pre-service teachers’ discourse on a WebCT Bulletin Board in their investigations
of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service
teachers conducted collaborative discourse in framing their research questions, conducting research and writing reports. The
science teacher educator provided feedback and carefully crafted prompts to help pre-service teachers develop and refine their
work. Overall, the online discourse formats enhance out-of-class communication and support collaborative group work. But the
discourse on the critical examination of one another’s point of views rooted in scientific inquiry appeared to be missing.
It is suggested that pre-service teachers should be given more guidance and opportunities in science courses in carrying out
scientific discourse that reflects reform-based scientific inquiry. 相似文献

This paper describes a module provided to first year elementary participants in a two-year after-degree Bachelor of Education
program. The module was specifically designed to address the fact that pre-service teachers can enter the B.Ed. degree with
little or no science knowledge. Science experiences were explicitly incorporated into the B.Ed. module described here linking
science content knowledge to specific science pedagogic content knowledge. The pre-service teachers were surveyed and interviewed
during and after completion of the module. It was found that the inquiry based approach increased the pre-service teachers'
level of science knowledge, their confidence with regard to teaching elementary science, and improved their attitude toward
science teaching and learning. 相似文献

The purpose of this quasi-experimental study was to determine the effects of a field-based, inquiry-focused course on pre-service teachers?? geoscience content knowledge, attitude toward science, confidence in teaching science, and inquiry understanding and skills. The field-based course was designed to provide students with opportunities to observe, compare, and investigate geological structures in their natural environment and to gain an understanding of inquiry via hands-on learning activities designed to immerse students in authentic scientific investigation. ANCOVA and MANCOVA analyses examining differences in outcome measures between students in the field experience (n?=?25) and education students enrolled in the traditional, classroom-based course (n?=?37) showed that students in the field course generally had significantly higher scores. Results provide evidence of the value of the field and inquiry-based approach in helping pre-service teachers develop the needed skills and knowledge to create effective inquiry-based science lessons. 相似文献

Pre-Service Teachers’ Maturing Perceptions of a TPACK-Framed Signature Pedagogy in Science Education
《学校用计算机》2012,29(1-2):53-69
Teacher education programs across North America are transforming. What were once piecemeal programs consisting of often unrelated courses are now becoming coherent and intertwined trajectories toward teacher certification. Part of this transformation can be attributed to the weaving of “signature pedagogies” throughout overarching program frameworks. A modern signature pedagogy within science teacher education is the integration of technology with science area content and effective pedagogy. In this article the author reports an action research study aimed toward promoting the “scholarship of teaching” of pre-service teachers through articulating changes in their maturing perceptions of the integrated relationship between technological, pedagogical, and science content knowledge. 相似文献

Constructing explanations and participating in argumentative discourse are seen as essential practices of scientific inquiry. The objective of this study was to explore the elements and origins of pre-service secondary science teachers’ alternative conceptions of tidal phenomena based on the elements used in Toulmin’s Argument Model through qualitative research. The data were collected from three pre-service secondary school teachers (D.-K. University, Teachers’ Colleges, junior and senior) in the Republic of Korea using a variety of qualitative research methods. We present three pre-service teachers as examples of 20 pre-service teachers for determining each pre-service teacher whether the pattern of his/her responses to all of the questions investigating a given concept can be explained by the consistent use of components of argument. The results of this study showed “the model with the Earth’s center at rest” backing their warrants as an element of Toulmin’s Argument Model. As a result, science educators must explicitly address these presuppositions or implicit beliefs and must help the students form links between their everyday experiences and scientific knowledge. Therefore, educators must be aware of the influence of students’ presuppositions and must use acceptable scientific concepts (the center of mass of the Earth–Moon system) based on argumentation to guide their construction of scientific concepts. 相似文献
