This article is focused on changes taking place in the teaching of science as part of general education. Over the past century a host of changes in the nature and practice of science have served to make outmoded the science curricula now found in school textbooks. Past and present reform efforts have been limited to updating traditional subject matter, which is not adequate for life and living in today's world. A new framework is required for a general education in science, one that is student centered and up‐to‐date on the nature of science technology. As stated in the Science Bulletin ( 2000 ), “Science and technology have become the driving force for mankind's quest for a better society” (p. 1). The new science curriculum also should be focused on the utilization of science technology for public welfare and human benefit. © 2002 John Wiley & Sons, Inc. J Res Sci Teach 39: 3–9, 2002 相似文献

This study investigated the experience of learners enrolled on an Open University (UK) French course, and included personality factors, motivation, and tutor and student roles. The data gathered via multiple elicitation methods gave useful insights into issues of special relevance to distance language education, in particular the lack of fit between an inherently social discipline such as language learning and the distance context, whose main characterizing feature is remoteness from others. Motivation was seen to play a crucial role in success, along with tutor feedback, and personal responsibility for learning. Increased confidence and self‐regulation were beneficial outcomes of the process of learning at a distance, and numerous suggestions for learning approaches based on personal experience were offered for language learners new to distance learning. The study concluded that the task for distance practitioners is to build on the insights shown by learners themselves, in order to target support where it is most needed. 相似文献

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general. 相似文献

WormBase is an open-access model-organism database that provides current and accurate genetic information of C. elegans and related nematodes. Users can search WormBase by several fields, including a gene or human disease. A special feature of the database is the inclusion of micropublications, peer-reviewed data that may go unpublished in traditional venues. 相似文献

The chapters included in this special issue are innovative in their attempt to bring together research on persuasion with research on conceptual change. Although persuasion and conceptual change are not similar in all respects, they both involve belief change. They also both require that we better understand the variables that make a text persuasive and thus influence the reader to change his/her beliefs. These chapters are instrumental in bringing about three important characteristics of persuasive text that can also be useful in inviting conceptual change. These characteristics are the comprehensibility, clarity and credibility of the text; the importance of explicitly addressing the readers’ prior beliefs; and affective and motivational factors. 相似文献

We argue that learning science requires children to move from perceptually based representations to more abstract conceptual representations and to understand that appearance may sometimes deceive us and that the same phenomenon in the world can have more than one representation when seen from different perspectives. We also argue that the beginnings of such an epistemological perspective can be found in young children’s ability to think about the difference between their beliefs and the beliefs of others in the social domain, i.e., their Theory of Mind. We present the results of two empirical studies that show significant correlations between children’s growing Theory of Mind, developing epistemological thinking, and science learning, and suggest that Theory of Mind tasks can be used to promote conceptual change in science. 相似文献
