Knowing,researching, and reporting science education: Lessons from science and technology studies

Recent research in science and technology studies changed the way we understand science as it is practiced—that is, how scientific knowledge emerges from social, natural, social, political, cultural, historical, and economic contingencies of scientific work. Many science educators agree that students should learn not only science but also about science. In this article, we (a) outline important findings, research methods, and ways of reporting research that emerged from science and technology studies; and (b) show how familiarity with science and technology studies research can provide science educators with valuable insights about curriculum design and research on learning. We conclude that science and technology studies can serve as a resource to science education and that there is a potential for conducting collaborative work between science education and science and technology studies. Such collaborations have the potential to yield better theories about how people become competent in science from childhood to adulthood. © 1998 John Wiley & Sons, Inc.

Interpretations of graphs by university biology students and practicing scientists: Toward a social practice view of scientific representation practices

Using graphs is a key social practice of professional science. As part of a research program that investigates the development of graphing practices from elementary school to professional science activities, this study was designed to investigate similarities and differences in graph‐related interpretations between scientists and college students engaged in collective graph interpretation. Forty‐five students in a second‐year university ecology course and four scientists participated in the study. Guided by domain‐ specific concerns, scientists' graph‐related activities were characterized by a large number of experience‐based, domain‐specific interpretive resources and practices. Students' group based activities were characterized by the lack of linguistic distinctions (between scientific terms) which led to ambiguities in group negotiations; there was also a lack of knowledge about specific organism populations which helped field ecologists construct meaning. Many students learned to provide correct answers to specific graphing questions but did not come to make linguistic distinctions or increase their knowledge of specific populations. In the absence of concerns other than to do well in the course, students did not appear to develop any general interpretive skills for graphs, but learned instead to apply the professor's interpretation. This is problematic because, as we have demonstrated, there are widely differing viable interpretations of the graph. Suggestions for changes in learning environments for graphing that should alleviate this problem are made. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 1020–1043, 1999     

Could probability be out of proportion? Self-explanation and example-based practice help students with lower proportional reasoning skills learn probability

Instructional Science - Proportional reasoning failures seem to constitute most errors in probabilistic reasoning, yet there is little empirical evidence about its role for attaining probabilistic...     

Learning how teachers learn in underdeveloped countries

This paper argues that practitioners and researchers in underdeveloped countries should organize themselves into teams to find and share research and experience-based information about factors that influence the quality of teaching. The teams would compile locally-developed knowledge about three topics: What teaching practices are most effective in classrooms? How do teachers who use those practices learn them? How and what should teacher training institutions teach teachers so that they will use effective practices? The paper briefly reviews published research to argue that the answers to the latter two questions are not yet fully developed, and especially not for underdeveloped countries.

A comparison of muscle activations during traditional and abbreviated tennis serves

The abbreviated tennis serve is a relatively novel modification of the traditional serve that has been reported to provide performance advantages over the traditional technique. However, there are limited objective data regarding the benefits and biomechanics of the abbreviated serve; no data exist that describe shoulder muscle activations during the abbreviated serve. The purpose of this study was to compare muscle activations between the traditional and abbreviated serves. Electromyographic data were collected for the anterior and posterior deltoid, infraspinatus, middle trapezius, latissimus dorsi, serratus anterior, and pectoralis major. When muscle activations were compared during each serve phase, no significant differences were observed between the traditional and abbreviated tennis serve techniques, indicating that the traditional and abbreviated serves are similar regarding shoulder muscle activations. These results could have implications for performance of and injury related to the abbreviated versus traditional serve technique. Although the abbreviated serve has anecdotally been described as advantageous, the present data do not indicate any significant advantages or disadvantages in performing the abbreviated serve technique versus the traditional serve.     

Senior High School Education in the 21st Century

Educators in senior high schools are used to hearing, “Senior high schools today look the same as they did a hundred years ago.” Though the author has heard this and similar comments, she also has heard a great number of high school students talking with excitement about their learning experiences. She has worked with teachers and administrators who are passionately committed to ensuring that secondary-level students receive a high-quality education, and she has reveled in hearing parents sing the praises of the high school their children attend. So is senior high school education unjustly receiving a bad rap? This article describes a Change Practice Initiative implemented by a school district in Canada to ensure that structures and practices at its high schools are geared to the changing needs of students and educators, and the outcomes of this endeavor.
