Argument as Professional Development: Impacting Teacher Knowledge and Beliefs About Science

Using a case study method, the experiences of a group of high school science teachers participating in a unique professional development method involving an argue-to-learn intervention were examined. The participants (N?=?42) represented 25 different high schools from a large urban school district in the southwestern United States. Data sources included a multiple-choice science content test and artifacts from a capstone argument project. Findings indicate although it was intended for the curriculum to be a robust and sufficient collection of evidence, participant groups were more likely to use the Web to find unique evidence than to they were to use the provided materials. Content knowledge increased, but an issue with teacher conceptions of primary data was identified, as none of the participants chose to use any of their experimental results in their final arguments. The results of this study reinforce multiple calls for science curricula that engage students (including teachers as students) in the manipulation and questioning of authentic data as a means to better understanding complex socioscientific issues and the nature of science.

Teaching With and About Nature of Science, and Science Teacher Knowledge Domains

The ubiquitous goals of helping precollege students develop informed conceptions of nature of science (NOS) and experience inquiry learning environments that progressively approximate authentic scientific practice have been long-standing and central aims of science education reforms around the globe. However, the realization of these goals continues to elude the science education community partly because of a persistent, albeit not empirically supported, coupling of the two goals in the form of ‘teaching about NOS with inquiry’. In this context, the present paper aims, first, to introduce the notions of, and articulate the distinction between, teaching with and about NOS, which will allow for the meaningful coupling of the two desired goals. Second, the paper aims to explicate science teachers’ knowledge domains requisite for effective teaching with and about NOS. The paper argues that research and development efforts dedicated to helping science teachers develop deep, robust, and integrated NOS understandings would have the dual benefits of not only enabling teachers to convey to students images of science and scientific practice that are commensurate with historical, philosophical, sociological, and psychological scholarship (teaching about NOS), but also to structure robust inquiry learning environments that approximate authentic scientific practice, and implement effective pedagogical approaches that share a lot of the characteristics of best science teaching practices (teaching with NOS).     

College Science, Mathematics, and Methods Teaching Faculty Talk About Science and Mathematics: An Examination of Faculty Discourse in a Reform-Based Teacher Preparation Program

In this study discourse and conversation analyses were performed on talk by science and mathematics teaching faculty participating in reforming content courses for teacher candidates participating in a mathematics and science teacher preparation project (upper elementary and middle level). The context of the study was the Maryland Collaborative for Teacher Preparation (MCTP), a National Science Foundation funded project in the USA. The study's goal was to explore the use of discourse and conversation analyses as ways to understand faculty beliefs concerning mathematics and science, two disciplines the MCTP project aimed to connect. Discussion focused on two areas: (1) the comparison of the discourse on science and mathematics by the science, mathematics, and pedagogy content specialists, and (2) the impact of collaboration on the science and mathematics teaching faculty's conversation on science and mathematics. An implication of this study is to promote the analysis of talk as way to inform and direct faculty transformation in science and mathematics teacher education programs. Future research is recommended.

Knowledge Integration in Science Teaching: Analysing Teachers' Knowledge Development

This paper tests the utility of a new sociocognitive frame for analysing the development of teachers' knowledge – the knowledge integration perspective (Linn, Eylon, & Davis, in press; Linn & Hsi, 2000). In doing so, the paper describes one prospective elementary teacher's developing knowledge and highlights its complexity. The prospective teacher demonstrates relatively well-integrated science subject matter knowledge, but she makes some problematic links to lessons and develops some instructional representations that show where she needs to distinguish between different scientific ideas. She also, however, links science concepts to appropriate real-world experiences, indicating that she has nascent useful pedagogical content knowledge. The paper discusses what teacher educators can learn about their learners from this analysis, argues for the utility of the knowledge integration perspective for conducting similar analyses, provides ideas to help science teacher educators apply the perspective easily as they teach their students, and points to areas ripe for future research.     

Beliefs about the Nature of Science and the Enacted Science Curriculum

This interpretive study of the teaching and learning of chemistry in an Australian high school examines the beliefs about the nature of science of a teacher and his class in relation to the enacted curriculum. Although the teacher and students tended to see science as an evolving discipline that was uncertain and changed over time, the manner in which the curriculum was implemented was a direct contrast. In the enacted curriculum science was represented as a catalogue of facts to be memorised and as algorithmic solutions to problems. The beliefs that had greatest impact on shaping the curriculum were the teachers beliefs about the nature of student learning, his beliefs about the distribution of power between himself and the students, and the extent to which restraints were accepted by the teacher as reasons for maintaining a traditional approach to teaching and learning chemistry.     

Impact of the Knowledge and Beliefs of Egyptian Science Teachers in Integrating a STS based Curriculum: A Sociocultural Perspective

The failure of much curriculum innovation has been attributed to the neglect by innovators of teachers’ perceptions. The purpose of this study was to investigate inservice science teachers views of integrating Science, Technology and Society (STS) issues into the science curriculum and identify the factors that influence their decisions concerning integrating STS issues (or not). The study used mixed methods (questionnaire and interviews) with Egyptian science teachers who teach science courses for 12- to 14-year-old students. The findings indicate that unless curriculum developers take account of teachers’ beliefs and knowledge and the sociocultural factors that shape or influence those beliefs in designing and planning new STS curriculum materials, these materials are unlikely to be implemented according to their intended plan.

Understanding Middle Students' Beliefs About Knowledge and Learning Using a Multidimensional Paradigm

Abstract

Recent theory (Schommer, 1990) suggests that personal epistemology is multidimensional. The multidimensional epistemology structure with middle school students was tested in this study. Over 1,200 students in Grades 7 and 8 completed an epistemological belief questionnaire. Prior theory, developed with college students, suggested 4 epistemological belief factors: Ability to Learn, Structure of Knowledge, Speed of Learning, and Stability of Knowledge. Confirmatory factor analysis applied to a random half of the sample indicated that a 3-factor model was a good fit to the data. That model was replicated with the second half of the data. Follow-up regression analyses indicated that the more students believed in gradual learning and incremental ability to learn, the higher GPA they earned.     

论科学课程发展的人文化趋势

由于科学技术的巨大成功，科学课程在二十世纪备受重视并得到迅速发展。但面对科学技术负面效应的不断显现和科学教育内部问题的接踵而至，人们开始反思科学课程，认为科学课程必须反映科学的化属性、正视科学技术的负面效应、关注科学在精神层面的育人功能、尊重儿童的个性发展、培养学生全面认识、理解、运用和评价科学的意识和能力。这为人们描绘了科学课程发展的人化趋势，因此有必要从社会背景、理论基础、基本主张和发展走向等方面对此进行深入分析和探讨。     

Preservice Science Teachers' Beliefs About Teaching and Learning: The Influence of K-12 Field Experiences

Teaching is a complex task shaped by many external and internal influences, including the beliefs held by individual teachers. This study sought an understanding of the impact of field experiences on the beliefs developed by preservice science teachers. The participants were students in an undergraduate science education methods course that involved observation and teaching experiences in K-12 classrooms. The data used in this qualitative study included drawings representing beliefs and in-depth interviews with selected participants. The findings indicate that beliefs focused on two key dualities: learning through experience and transmission and student-centered and teacher-centered instruction. The findings also suggest that field experiences both reinforce and challenge the beliefs held by preservice science teachers.

Beliefs About Knowledge,Knowing, and Learning: Differences Across Knowledge Types in Physics

The authors examined whether students’ epistemic and learning beliefs varied across different knowledge types in physics. On the basis of various beliefs frameworks, the authors predicted that individuals’ beliefs would vary within a domain across the same content when presented conceptually versus procedurally. Participants were 81 high school students enrolled in an advanced physics course. Students completed a conceptually oriented test and a procedurally oriented test on the same content 1 week apart, and they immediately responded to the Epistemological Beliefs Assessment for Physical Science questionnaire after completion of each test. Results revealed that girls espoused more constructivist beliefs about physics for conceptual knowledge than for procedural knowledge, whereas the opposite was found for boys. Moreover, female students espoused more constructivist beliefs than did male students across both types. These results have important theoretical and methodological implications.     

Effects of Academic Discipline and Teaching Goals in Predicting Grading Beliefs Among Undergraduate Teaching Faculty

Prior research reveals that differential grading patterns exist among the academic disciplines. One explanation may lie in discipline-related differences in teaching goals and beliefs about the meaning grades should convey. This study examined the effects of academic discipline and teaching goals on grading beliefs. A national sample (n = 442) of undergraduate teaching faculty provided responded to a survey measuring the importance of various teaching goals and orientations toward norm-referenced or criterion-referenced grading (Frame of Reference), and beliefs about using grades to sort and select students on the basis of achievement (Gatekeeping). Both teaching goals and academic discipline were significantly related to gatekeeping beliefs, but not to beliefs about frames of reference for grading. Higher gatekeeping scores were associated with faculty in the paradigmatic fields and those who emphasized analytic skills and time management. Lower gatekeeping scores were associated with the preparadigmatic disciplines and teaching goals of synthesis and integration and developing respect for others. Faculty who identified their primary teaching role as subject matter oriented were more gatekeeping than those who identified themselves primarily as being student/personal development oriented.     

Participation, Knowledge and Beliefs: A Community Perspective on Mathematics Learning

In this paper I illustrate the use of a particular situated method of interpretation in my analysis of the data from 3-year case studies of two schools. The constraints and affordances provided by different environments are shown to be key analytical tools in understanding the ways in which students develop and make use of knowledge. Various classroom incidents are analysed, demonstrating that the particular constraints and affordances of formalised mathematics classrooms, to which students become attuned, contribute to the development of learning identities that are peculiar to the school mathematics classroom and of limited use to students in the real world. An understanding of the mathematics classroom as a particular community of practice is central to this analysis.This revised version was published online in September 2005 with corrections to the Cover Date.
