Epistemological framing and novice elementary teachers' approaches to learning and teaching engineering design

As engineering learning experiences increasingly begin in elementary school, elementary teacher preparation programs are an important site for the study of teacher development in engineering education. In this article, we argue that the stances that novice teachers adopt toward engineering learning and knowledge are consequential for the opportunities they create for students. We present a comparative case study examining the epistemological framing dynamics of two novice urban teachers, Ana and Ben, as they learned and taught engineering design during a four-week institute for new elementary teachers. Although the two teachers had very similar teacher preparation backgrounds, they interpreted the purposes of engineering design learning and teaching in meaningfully different ways. During her own engineering sessions, Ana took up the goal not only of meeting the needs of the client but also of making scientific sense of artifacts that might meet those needs. When facilitating students' engineering, she prioritized their building knowledge collaboratively about how things work. By contrast, when Ben worked on his own engineering, he took up the goal of delivering a product. When teaching engineering to students, he offered them constrained prototyping tasks to serve as hands-on contexts for reviewing scientific explanations. These findings call for teacher educators to support teachers' framing of engineering design as a knowledge building enterprise through explicit conversations about epistemology, apprenticeship in sense-making strategies, and tasks intentionally designed to encourage reasoning about design artifacts.     

Exploring the real-world decision-making of novice and experienced teachers

For the past two decades, those involved in teacher training have encouraged teachers to incorporate evidence from research into a process of critical reflection to improve the quality of their decisions. Using research as part of a deliberative reflective process has been thought to enable teachers to learn from their practice. However, teachers’ decision-making has proven highly impervious to external influence. Teachers often resist reflective models that attempt to take their thinking to deeper, critical levels and are unlikely to use empirical evidence to inform their decisions. Given these conditions, this study seeks further insight into teachers’ pedagogical decision-making amidst the complex dynamics of ‘real-world’ educational contexts. Based on a systematic review of over three decades of decision research, a questionnaire was developed to investigate the decision process of 80 pre- and in-service teachers working in the post-compulsory sector. Data were analysed to uncover how these teachers made sense of the range of information that came into play when deciding how to resolve a pedagogical issue and the sources they used to inform their decision-making. If those involved in pre- and in-service teacher training could build upon teachers’ intrinsic decision processes, they could potentially support greater decision effectiveness.

Student teachers' attitudes toward science and science teaching

Attitudes toward science and science teaching are the subject of a mounting body of research on teachers. A widely used instrument developed by researchers in the United States appears to be relevant to the Australian context and was considered appropriate for measuring attitudes of preservice student teachers attending a College of Advanced Education in Brisbane. The findings suggest that much more effort needs to be concentrated on fostering desirable attitudes toward science and the teaching of science among future primary school teachers.     

A constructivist approach to change in elementary science teaching and learning

Constructivism is a set of beliefs that can be used by teachers to think about learning and teaching and to plan and enact a science curriculum. This paper is a fictional account of an elementary science teacher and her use of constructivism as a referent for her various roles as a science teacher. The paper also describes how the teacher came to teach in this manner, describing her involvement in staff development activities and an evolution in her thinking from an ojectivist to a constructivist system of semantics. Implications are presented for the reform of science education.     

Prospective teachers' conceptions of teaching and learning revealed through metaphor analysis

This study investigated the metaphors that prospective teachers in Turkey (N = 1,142) formulated to describe the concept of “teacher”. Participants completed the prompt “A teacher is like… because…” by focusing on only one metaphor to indicate their conceptualization of teaching and learning. Altogether 64 valid personal metaphors were analyzed and 10 main conceptual themes were identified. Significant associations were detected between participants' gender and study program type and six of the conceptual themes. Metaphors seem to provide a powerful cognitive tool in gaining insight into prospective teachers' professional thinking.     

Investigation of preservice elementary teachers' thinking about science

It is not uncommon to find media reports on the failures of science education, nor uncommon to hear prestigious scientists publicly lament the rise of antiscience attitudes. Given the position elementary teachers have in influencing children, antiscience sentiment among them would be a significant concern. Hence, this article reports on an investigation in which preservice elementary teachers responded to the Thinking about Science survey instrument. This newly developed instrument addresses the broadrelationship of science to nine important areas of society and culture and is intended to reveal the extent of views being consistent with or disagreeing with a commonly held worldview of science portrayed in the media and in popular science and science education literature. Results indicate that elementary teachers discriminate with respect to different aspects of culture and science but they are not antiscience. © 2002 Wiley Periodicals, Inc.

Experienced teachers' knowledge of teaching and learning of models and modelling in science education

This article reports a study of the knowledge of experienced science teachers in the context of a reform in science education in The Netherlands. The study focused on a major goal of the reform, that is, improving students' knowledge and abilities in the field of models and modelling in science. First, seven teachers of biology and chemistry were interviewed about the teaching and learning of models and modelling in science. Next, a questionnaire was designed consisting of 30 items on a Likert-type scale. This questionnaire was completed by a group ( n = 74) of teachers of biology, chemistry and physics. Results indicated that the teachers could be grouped in two subgroups, who differed in terms of their self-reported use of teaching activities focusing on models: one sub-group applied such activities substantially more often than the other sub-group. This distinction appeared not to be related to the teachers' subject, or teaching experience. Moreover, the use of teaching activities seemed only loosely related to the teachers' knowledge of their students, particularly, students' views of models and modelling abilities. Implications for the design of teacher education are discussed.     

Fostering a community of practice through a professional development program to improve elementary teachers' views of nature of science and teaching practice

This study explored the development of a community of learners through a professional development program to improve teachers' views of nature of science (NOS) and teaching practice. The Views of Nature of Science questionnaire and interviews were used to assess teachers' conceptions of NOS three times over the course of the study. Notes and videotapes taken during workshops and classroom observations were used to track influence of the community of learners on classroom practice. The community of practice (CoP) was fostered through an intensive summer workshop, monthly school site workshops, and classroom support to aid teachers in incorporating new techniques and reflecting upon their learning and practice. We found that teachers became aware of their changes in views about NOS once they struggled with the concepts in their own teaching and discussed their struggles within the professional development community. The CoP on its own was not sufficient to change teacher's practice or knowledge, but it created a well‐supported environment that facilitated teacher change when paired with NOS modeling and explicit reflection. Cases of three teachers are used to illustrate changes in views and teaching practice common to the teachers in this study. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 1090–1113, 2009     

Exploring the use of virtual reality by pre-service elementary teachers for teaching science in the elementary classroom

Abstract

This research was conducted on two groups of pre-service elementary teachers (PSETs) (N?=?38) in a pre/post within-subjects design. Participants were asked to critique, create, and evaluate the use of virtual reality (VR) classroom applications during a three-stage intervention. Pre/post questionnaires assessed the change in attitudes toward using VR and technology when teaching. Participants felt significantly more ready to teach science using computer-based technology (t = 7.23, p < .0001) following the intervention. Qualitative analysis of responses showed that PSETs were positive about their VR experience and had come to see VR apps as supplementary educational tools. The majority of the PSET teams successfully created original instructional material using VR, increasing their self-efficacy.     

Taiwanese science students' and teachers' perceptions of the laboratory learning environments: Exploring epistemological gaps

The purpose of this study was to explore the differences between science students' and teachers' perceptions of laboratory environments. More than 1000 junior high school students and their science teachers in Taiwan were surveyed. The students showed much more dissatisfaction with approaches to laboratory activities than their teachers. They preferred a much more student-cohesive, open-ended, integrated and rule-clear laboratory environment than their teachers expected or preferred. However, the teachers sampled showed higher preferences for better equipment and material environments for laboratory work than did their students. Data from follow-up interviews with participant teachers suggested that epistemological views about science might be one of the important factors causing differences in perceptions between students and teachers of laboratory learning environments.     

Becoming a science teacher: First year teachers' approaches to learning about teaching

This paper discusses some of the issues arising from the first year of a longitudinal study into the career development of science teachers. It deals with the influences on, and approaches to, teaching by first year science teachers. Eighteen science graduates who had completed a Diploma in Education in 1990, were interviewed about their first year's teaching experiences. The participants explored issues ranging from the influences on their approach to teaching, student learning, determinants of a good lesson, the role of pre-service teacher training, and teaching as a career. Specializations: Science education, reflective practice, teaching and learning.

Learning science through talking science in elementary classroom

Elementary students in grade two make sense of science ideas and knowledge through their contextual experiences. Mattis Lundin and Britt Jakobson find in their research that early grade students have sophisticated understandings of human anatomy and physiology. In order to understand what students’ know about human body and various systems, both drawings and spoken responses provide rich evidence of their understanding of the connections between science drawings and verbal explanations. In this forum contribution, we present several theoretical connections between everyday language and science communication and argue that building communication skills in science are essential. We also discuss how young participants should be valued and supported in research. Finally we discuss the need for multimodal research methods when the research participants are young.     

Trends in teachers' recommendations for changing elementary and junior-high school science programs

Since 1978 many studies have called for changes in the practices of science teaching. These changes in instruction will occur only when the teachers decide to change their practices. This study uses surveys to consider the question of what were the trends in the teachers' recommendations for changes in elementary and junior-high school science programs between the years of 1978 and 1982. Large samples of teachers in British Columbia, Canada, responded anonymously to questionnaires in these years: 3040 teachers in 1978 and 1631 in 1982, with return rates ranging from 77.5% to 85%. These teachers described themselves as shifting their classroom practices toward ones that emphasize passive learning and memorization. The British Columbia Science Assessments recommend more inservice programs to stop this trend. There were very few differences in the teachers' recommendations for changes in the schools. The elementary-school teachers had major changes in their rankings of only two activities: they increased their ranking of “activity-centered learning” and reduced their ranking of “outdoor education.”
