The co-evolution of situated language and physics knowing

This study focuses on the evolutionary changes in students' language concerning animated objects and associated vector diagrams in a computer-based Newtonian microworld. Emergence, convergence, and interpretive flexibility are introduced as analytical notions to describe and explain changes in student discourse. The present analysis documents how new ways of taling emerge and how the convergence of meaning within student groups and towards scientific meanings arises from the affordances provided by the interpretive flexibility of objects and events in the microworld, the conversations with the teacher, and the microworld as backdrop which assures the topical cohesion of student talk. In the students' learning process, computer microworlds were not cultural tools which embed unique meanings that students can recover on their own. Rather, these microworlds achieved their meaning in part through the teacher's situated practices.     

Effect of context and gender on application of Science Investigation Skills

Two parallel versions of a Test of Science Investigation Skills were developed to assess students' application of science investigation skills in biology and physics contexts. Repeated pilot testing and critical appraisal were used to ensure the validity of the tests and their equivalence. Both versions of the test were administered to 112 Year 10 science students. The results indicated a satisfactory level of test reliability, the test set in a physics context proved to be significantly more difficult than the test set in a biology context, and mean scores for male and female students were not significantly different.

NARST: a lived history

In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living history that both shapes and was shaped by the biographies of its members.

The development of science process skills in authentic contexts

Instructional strategies and curriculum sequences aimed at teaching process skills have received considerable attention in science education. On the other hand, the teaching of domain-independent, context-free skills has been subject to criticism on the ground that important aspects of cognitive activities are functions of meaningful contexts. The intent of this study was to examine the development of integrated process skills in the context of open-inquiry laboratory sessions. The data-collection approach was qualitative and included videotapes of laboratory sessions, laboratory reports of students, and the reflective journals kept by the two teachers involved in the study. Forty-eight students from the Grade 11 introductory physics course, 29 students from the Grade 12 physics course, and 60 students from the Grade 8 general science course from an all-boys private school participated in the study. An interpretive research methodology was adopted for construction of meaning from the data. Students worked in collaborative groups during all of the open-inquiry laboratory sessions. Findings from the study indicate that students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of personal relevance in authentic contexts. Students learned to (a) identify and define pertinent variables, (b) interpret, transform, and analyze data, (c) plan and design an experiment, and (d) formulate hypotheses. Findings of this study suggest that process skills need not be taught separately. Integrated process skills develop gradually and reach a high level of sophistication when experiments are performed in meaningful context.     

Creative Thinking in Five and Six‐Year‐Old Kindergarten Children

This study was carried out to investigate the effect of age and sex on the creativity of 5 to 6‐year‐old kindergarten children. The total points scored by the 6‐year‐old boys and girls included in this study were found to be higher than those scored by the 5‐y ear‐olds. No significant difference was found between the points scored by the girls and boys. However, the girls did better in flexibility, originality and elaboration and the boys in fluency criterion of creativity.

Children should be helped at home and school to develop their creative power. To achieve this, art, story‐telling, music and drama activities should be an integral part of the school curriculums. During such activities children should be allowed to take their time, and any despotic attitude on the part of the teacher should be avoided. In addition, children should be given a chance with unstructured play materials. Activities should be followed by a discussion with children, who should be taught that things can be done in more ways than one.     

Coteaching: Creating resources for learning and learning to teach chemistry in urban high schools

How do new teachers become confident and competent while they are interns in inner‐city neighborhood schools challenged by many problems, often associated with economic shortfalls and cultural differences between the students and their teachers? Many science teacher education programs place a lot of emphasis on the planning stages of curriculum. But considerable discrepancies emerge between planned and lived curriculum, particularly in inner‐city, comprehensive high schools, and especially in classrooms that honor student interests and culture as starting points for learning. Previous research showed that coteaching provides opportunities for learning to teach even though the lived curriculum emerges often in unpredictable ways from the dialectic of collective (teacher and students) agency and structure. The present study allowed us to understand the underlying processes: the presence of a coteacher increases access to social and material resources, and thereby increases opportunities for actions that otherwise would not occur. Greater teaching opportunities provide newcomers with greater opportunities of learning to teach. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 882‐904, 2004.     

Lessons on and from the dihybrid cross: An activity–theoretical study of learning in coteaching

During their training, future teachers usually learn the subject matter of science. However, they are largely left on their own when it comes to figuring out how to teach this subject matter, that is, how to find appropriate pedagogical forms. In this article we present a model of collective teaching and learning, which we term coteaching/cogenerative dialoguing, as a way to build deep learning of science concepts while learning about alternative ways to teach the same subject matter. As praxis, coteaching brings about a unity between teaching and learning to teach; cogenerative dialoguing brings about a unity between teaching and researching. Both are potential sites for deep learning. We articulate coteaching/cogenerative dialoguing in terms of activity theory and the associated first‐person research methodology that has been developed by critical psychologists as a method of choice for dealing with the theory–praxis gap. Our detailed case study highlights opportunities of learning subject matter and pedagogy by university professors who participate in coteaching/cogenerative dialoguing in an urban high school. © 2002 Wiley Periodicals, Inc.

Educational technology as a key to educational innovation:

Instructional technology, especially the use of computers and the Internet has been lagging behind in the German educational system in comparison to other European countries. When this lack was realized in the second half of the 1990s it had quite a “shock-effect” but one of the healthy kind: Since then numerous public and private initiatives have been started to advance the use of technology in schools, higher education, and in vocational training. At the college and university level, there is a trend towards connecting online and offline courses. Also, it was understood that it is not enough to just provide schools and universities with the technology needed but that the introduction of technology has to be accompanied by profound systemic and structural changes. Thus, there is great hope that the use of technology in education will fuel educational innovations at all levels needed for educating and training pupils and students to act as responsible and media-literate citizens in a modern world.     

Developing and refining mental models in open-ended learning environments: A case study

This qualitative case study focused on the nature of science learning through open-ended problem solving. Twelve eighth graders were asked to find, frame, and resolve subproblems associated with structural failures resulting from earthquakes. Coded interviews, artifacts, and observations from the four-week study suggested students only partially derived accurate mental models about earthquake engineering problems. Recommendations for improving student problem understanding in open-ended environments include the explication of student hypotheses related to problems, and the continual testing of belief via analogical reasoning, research, communication, and tool use.
