Understanding of the Earth/Sun/Moon system represents a major cultural nexus in the history of ideas as well as being an important conceptual area in junior science teaching. The situation is one in which the objects in question can be observed but do not lend themselves to hands‐on experience in the case of the Sun and Moon or to obvious meaningful experience of the system in the case of the Earth. Children from 9 to 12 years of age were questioned using a clinical interview technique and stimulus materials, about the shape, size and motion of the Earth, Sun and Moon. A number of alternative views appear to be held. The use of a similar procedure with a group of children would seem to offer a powerful teaching methodology in which both teacher and students gain from the dialectic learning situation that is developed by this technique ‐ apart from providing insights concerning children's understanding. 相似文献

While genetics has remained as one key topic in school science, it continues to be conceptually and linguistically difficult for students with the concomitant debates as to what should be taught in the age of biotechnology. This article documents the development and implementation of a two‐tier multiple‐choice instrument for diagnosing grades 10 and 12 students’ understanding of genetics in terms of reasoning. The pretest and posttest forms of the diagnostic instrument were used alongside other methods in evaluating students’ understanding of genetics in a case‐based qualitative study on teaching and learning with multiple representations in three Western Australian secondary schools. Previous studies have shown that a two‐tier diagnostic instrument is useful in probing students’ understanding or misunderstanding of scientific concepts and ideas. The diagnostic instrument in this study was designed and then progressively refined, improved, and implemented to evaluate student understanding of genetics in three case schools. The final version of the instrument had Cronbach’s alpha reliability of 0.75 and 0.64, respectively, for its pretest and the posttest forms when it was administered to a group of grade 12 students (n = 17). This two‐tier diagnostic instrument complemented other qualitative data collection methods in this research in generating a more holistic picture of student conceptual learning of genetics in terms of scientific reasoning. Implications of the findings of this study using the diagnostic instrument are discussed. 相似文献

Following up on an earlier issue of The Curriculum Journal (Vol. 16, No. 1), this article focuses on learning outcomes in the context of video games. Learning outcomes are viewed from two theoretical frameworks: Kirkpatrick's levels of evaluation and the CRESST model of learning. These are used to analyse the outcomes claimed in journal articles that report empirical work, indicating the usefulness of the frameworks, and the necessity to consider the role of affective learning. The article ends with some comments on the relationship of instructional design to effective games and learning outcomes. 相似文献

This article investigates the content and effects of political humor on late-night television. Besides conducting a systematic content analysis of a Swiss late-night show, this article examines the effects of late-night political parody on competence evaluations of politicians. An experiment manipulated the televised parody of a politician and measured political knowledge. Results show that exposure to a televised political parody decreased competence ratings of politicians only for individuals high in political knowledge. The reason is that viewers must already have an understanding of current political affairs to “get the joke”—that is, the implicit message transported by the parody. The implications of such a negative “Tina Fey Effect” are discussed. 相似文献

This article examines relations between Facebook® (FB) use and social capital among 530 undergraduate students. The results demonstrated that using FB habitually was associated with gains in online bridging and offline network capital. This study also examined 2 motivations for using FB: the motivation to socialize with others and the motivation to improve one's status. Results showed that using FB for sociability reasons was associated with increased online bridging and bonding. Using FB more for status than for sociability was not associated with decreased online bridging and bonding. Finally, the results provided evidence of the sociability motivation mediating the relationship between FB habit and online bridging and bonding. Theoretical implications are discussed. 相似文献
