Myths of Environmental Education

Abstract

A review of environmental education literature reveals a paucity of constructivist-based research. To support the case for this approach, the author reviews theoretical aspects of science education research of this type. It first situates different approaches to educational research in relation to different epistemologies and then reviews constructs used in constructivist science education research. Issues associated with the adoption of this epistemology—topics deemed worthy of research, importance given to the learner's pre-instructional knowledge, and perspectives on learning and understanding—are considered. The article concludes with proposals for constructivist research in environmental education across the educational commonplaces.     

An analysis of teacher questioning behaviour in constructivist primary science education using a modification of a descriptive system designed by Barnes and Todd (1977)

An analytical framework was developed (after Barnes and Todd 1977) to enable both the cognitive and social aspects of teacher questioning in constructivist primary science education to be explored. The data categorized within this framework were collected both before and after a period of questioning INSET in the forms of audio‐taped discussions between teacher and children; audio‐taped, focused interviews between teacher and researcher; and reflective written assignments. The categories used within the framework enabled distinctive individual profiles to be identified for the participating teachers, and the manner in which these profiles changed over time could be charted. The potential for developing the usefulness of this framework for future work is considered in terms of refining some categories and improving the research design. It is suggested that the framework could be a useful diagnostic tool to help teachers develop their use of a child‐centred, constructivist teaching philosophy in primary science education.     

The construction and use of a metaphor for science teaching

While constructivism has emerged as a major reform in science education from the last decade, wide-spread adoption of constructivist practices in school laboratories and classrooms is yet to be achieved. If constructivist approaches are to be utilised more widely, teachers will need to accept a more active and constructivist role in their own pedagogical learning. One experienced junior science teacher was able to implement constructivist approaches in her classroom by using a personally constructed metaphor to guide her practice.

Helping Primary Student Teachers Understand Pupils' Learning: Exploring the student‐mentor interaction

The school-based task is firmly established in teacher education in the UK. In the study reported, primary student teachers carried out tasks exploring children's learning in science and were told to discuss the outcomes with their classteacher-mentors. The tasks and their university-based training followed a "constructivist" approach to learning science. The mentors' role in debriefing school-based tasks has been assumed to be one of "reflective practitioner" able to unpack issues of pedagogy with the student teacher. The research reported here shows that discussions often lacked depth or reflected a superficial or different understanding of constructivism by mentors that conflicted with the student teachers' aspirations. The implications of the research for future practice in teacher education and specifically for the training of mentors in science are discussed.     

Developing a material-dialogic approach to pedagogy to guide science teacher education

Abstract

Dialogic pedagogy is being promoted in science teacher education but the literature on dialogic pedagogy tends to focus on explicit voices, and so runs the risk of overlooking the important role that material objects often play in science education. In this paper we use the findings of a teacher survey and classroom case study to argue that there is a gap in the way that science teachers think about the role of materials and that this could be addressed by changes in the theory base of teacher training, augmenting the current constructivist and dialogic theory with the addition of new materialism in the form of Barad’s ‘Agential Realism’. Our findings suggests that science teachers do not regularly explicitly consider the relationship between the material resources they deploy and the dialogic learning taking place. We argue that science teacher training and professional development should pay more attention to the material-dialogic relationships in the learning that emerges in science classrooms.     

Environment in the science curriculum: The politics of change in the Pan-Canadian science curriculum development process

This paper draws on the experience of the Pan-Canadian science curriculum development process as an instance of the more general problem of integrating science and environmental education. It problematizes the issue of incorporation of social and environmental dimensions within the science curriculum in terms of both policy and practice. The agenda of environmental education, as eco-philosophical and eco-political, provides a radically different base from which to explore the impact of change on science teachers and schools. Thus, the very idea of environmental education as an educational policy goal must be examined in light of conflicting agendas of science and environmental education. This paper argues that transforming structures and processes of school science to enable different teacher and student roles involves closing the gap between curriculum (policy) development and professional development as well as reconceptualizing science education, but from more overtly open moral value and political perspectives than have been considered in the literature of science education.     

The effect of culture on the learning of science in non‐western countries: the results of an integrated research review

Abstract

An increasing number of researchers are investigating the effect of students’ prior knowledge and beliefs on their development of scientific concepts. Much of this research is taking place within the framework of constructivism, and is attracting the attention of science educators in non‐western countries. This integrative research review has been undertaken to help researchers and practitioners to identify issues for further investigation and reflection. The results suggest that ‘cosmetic’ attempts to nationalize western science curricula in non‐western countries are likely to prove ineffective because the problem, from the students’ perspective, is one of poor ‘fit’ between their world‐views, language meanings and prior beliefs and those inherent in the subject. A constructivist paradigm seems to offer good prospects for both understanding the problem and formulating learning strategies in science education which are better suited to non‐western cultures. Nevertheless, constructivist pedagogies imported from the West should be examined for their cultural appropriateness.

Changing Teachers' Thinking Through Critical Constructivism and Critical Action Research

Abstract

This paper studies attempts to change teachers' thinking towards a construc‐tivist perspective within science education. The contexts surrounding the research are important: ideas of critical constructivism, critical action research and the work of Paulo Freire are brought to bear on teacher education in Recife, northeastern Brazil. A professional development course was designed to explore with secondary science teachers some elements of constructivist thinking, and to shape action research projects within their own classrooms. The course design is described, along with some of the responses of the participants both during and after they undertook their projects within their secondary schools. The responses highlight the tensions of trying to innovate with ‘non‐traditional methods’ within traditional situations, the advantages and drawbacks of ‘freeing up’ classroom discussion and authoritative teaching.     

BOOK REVIEW

Abstract

This paper draws on established teacher education programmes at the Universities of Bath and Canberra in order to contrast different approaches to environmental education contained in secondary science teacher training courses in the two countries. The paper begins with an examination of the context, purposes and approaches of the two courses, leading to a critical review and a discussion of pertinent developmental issues within teacher training programmes and the relationship between science education and environmental issues.     

Teachers' knowledge of models and modelling in science

This study investigated the knowledge that experienced science teachers have of models and modelling in science in the context of a school curriculum innovation project in which the role and the nature of models and modelling in science are emphasized. The subjects in this study were teachers of biology, chemistry and physics preparing for the curriculum innovation. Two instruments were used: a questionnaire with seven open items on models and modelling, which was completed by 15 teachers, and a questionnaire consisting of 32 items on a Likert-type scale (n=71). Results indicated that the teachers shared the same general definition of models. However, the teachers' content knowledge of models and modelling proved to be limited and diverse. A group of teachers who displayed more pronounced knowledge appeared to have integrated elements of both a positivist and a social constructivist epistemological orientation in their practical knowledge. Implications for the design of teacher education interventions are discussed.     

Evaluating constructivist beliefs of teacher candidates

Abstract

Teacher education programs that want their future teachers to embrace and employee constructivist principles must strive to provide opportunities for teacher candidates to develop an understanding of constructivism. The paper presents a structure for embedding constructivist principles into early childhood and elementary teacher education courses and the results of a pilot study at a Mid‐Western University. The results of the study demonstrate that teacher candidates believe that constructivist practices are very to extremely important. In addition, their responses indicated that the teacher candidates believe that their role in a constructivist environment is very to extremely important. The study reinforces the importance of providing experiences in teacher education programs that will result in positive views of constructivism. © 2005 Elsevier Inc. All rights reserved.

Computer Technology in an Authentic Science Project

Summary

While a constructivist approach to the integration of technology in the science curriculum can enable teachers to educate students on the cyclical nature of the research process and interrelate various scientific concepts, there are several considerations for educators must take to assure that it is done effectively. The authors provide a review of a project that was designed and implemented for high school science students that integrated the use of technology in a constructivist environment. This review summarizes the strengths and limitations of the project and provides educators with further considerations when implementing such a project. As educators become more familiar with what is required to successfully integrate technology in a constructivist environment, the limitations and obstacles that may be encountered can be limited. More research devoted to the use of computer technology to teach science process skills will bring teachers and students closer to harnessing the potential powers of both project-based learning strategies and the computer environment.     

Constructivism in Practice: an Exploratory Study of Teaching Patterns and Student Motivation in Physics Classrooms in Finland,Germany and Switzerland

For the last three decades, moderate constructivism has become an increasingly prominent perspective in science education. Researchers have defined characteristics of constructivist-oriented science classrooms, but the implementation of such science teaching in daily classroom practice seems difficult. Against this background, we conducted a sub-study within the tri-national research project Quality of Instruction in Physics (QuIP) analysing 60 videotaped physics classes involving a large sample of students (N?=?1192) from Finland, Germany and Switzerland in order to investigate the kinds of constructivist components and teaching patterns that can be found in regular classrooms without any intervention. We applied a newly developed coding scheme to capture constructivist facets of science teaching and conducted principal component and cluster analyses to explore which components and patterns were most prominent in the classes observed. Two underlying components were found, resulting in two scales—Structured Knowledge Acquisition and Fostering Autonomy—which describe key aspects of constructivist teaching. Only the first scale was rather well established in the lessons investigated. Classes were clustered based on these scales. The analysis of the different clusters suggested that teaching physics in a structured way combined with fostering students’ autonomy contributes to students’ motivation. However, our regression models indicated that content knowledge is a more important predictor for students’ motivation, and there was no homogeneous pattern for all gender- and country-specific subgroups investigated. The results are discussed in light of recent discussions on the feasibility of constructivism in practice.     

Environmental Education Course Development for Preservice Secondary School Science Teachers in the Republic of Korea

Abstract

In Summer 1996, an opinionnaire survey was used to evaluate the opinions of Korean professors, in earth science education and geology departments, about the science concepts related to environmental issues that might be important for secondary preservice earth science teachers in the Republic of Korea. The opinionnaire contained 63 items within the 14 major topics being considered. It used a 4-choice, Likert-type scale and was completed by 47 professors (response rate = 51%). There was a good coincidence in opinions on major topics to be included. Respondents favored an environmental earth science course that emphasized the “human impact on the environment” rather than “natural environmental hazards.” Also, they favored study of natural hazards that commonly occur in Korea within a context of worldwide natural hazards.     

Classroom conceptual change: philosophical perspectives

Researchers of students’ concepts and conceptual change frequently draw analogies to the history of science. The analogy is generally presented when comparing students’ scientific concepts to similar ones in the history of science. We have tried to show the importance of this analogy on a higher level ‐‐ that of understanding the process of conceptual change in general among students.

This article outlines a number of lines in the philosophy of science and analyses differences between the perspectives of a number of broadly constructivist positions which have developed during this century.

The analysis is used to clarify the theoretical basis on which research into student conceptual change is conducted and interpreted.     

Examining the literacy component of science literacy: 25 years of language arts and science research

This review, written to celebrate the 25th anniversary of the International Journal of Science Education, revealed a period of changes in the theoretical views of the language arts, the perceived roles of language in science education, and the research approaches used to investigate oral and written language in science, science teaching, and learning. The early years were dominated by behavioralist and logico-mathematical interpretations of human learning and by reductionist research approaches, while the later years reflected an applied cognitive science and constructivist interpretations of learning and a wider array of research approaches that recognizes the holistic nature of teaching and learning. The early years focus on coding oral language into categories reflecting source of speech, functional purpose, level of question and response, reading research focused on the readability of textbooks using formulae and the reader's decoding skills, and writing research was not well documented since the advocates for writing in service of learning were grass roots practitioners and many science teachers were using writing as an evaluation technique. The advent of applied cognitive science and the constructivist perspectives ushered in interactive-constructive models of discourse, reading and writing that more clearly revealed the role of language in science and in science teaching and learning. A review of recent research revealed that the quantity and quality of oral interactions were low and unfocused in science classrooms; reading has expanded to consider comprehension strategies, metacognition, sources other than textbooks, and the design of inquiry environments for classrooms; and writing-to-learn science has focused on sequential writing tasks requiring transformation of ideas to enhance science learning. Several promising trends and future research directions flow from the synthesis of this 25-year period of examining the literacy component of science literacy - among them are critical listening and reading of various sources, multi-media presentations and representations, effective debate and argument, quality explanation and the role of information and communication technologies/environments.     

Issues of teaching science to nurses in the tertiary sector

The shift of nurse education from the hospitals to higher education institutions has resulted in a large pool of students within the Universities requiring basic science instruction. Most of these students are female, often mature age, with limited science backgrounds. This paper discusses the type of science education demanded by the nursing profession, the view of science as a subject held by these students, and the key role played by constructivist thinking in dealing with both of these. Specializations: The language of science textbooks; relations between science and literature; science in nursing education.
