In this article we describe the way we teach our students a systematic problem solving method in a computer assisted learning project on ‘Dynamics for mechanical engineering’, Animations are used to enhance insight and motivation. We briefly discuss the theoretical foundations of systematic problem solving, and the role of animations. One of the dynamics problems will be described in more detail. Finally, we remark on the development tools used in the Windows environment. 相似文献

Cognitive load theory has challenged contemporary approaches to teaching by arguing that they are ineffective because of a neglect of the psychology underpinning learning and, specifically, the high demand placed on working memory. This paper challenges the presuppositions involved not only in arguments for guided instruction by those supporting cognitive load theory, but also in opposed pedagogic approaches involving discovery and inquiry learning. Both approaches are in danger of presupposing what C.B. Macpherson criticised as ‘possessive individualism’—i.e. capacities, beliefs and desires viewed as possessions of an individual. As a result, they fail to pay attention to mediation and normativity, both of which are distinctive aspects of human action. Examining this in more detail entails consideration of fundamental issues concerning human knowledge and understanding. An appreciation of the significance of normativity and mediation leads us to the philosophic works of Marx, Vygotsky and Wittgenstein, and in particular to Brandom's Inferentialism. The philosophical ideas here have direct implications for pedagogy. 相似文献

目的:本研究旨在测定Scandix pecten-veneris L.的植物素和评价其生物学潜力。方法:测定S.pecten-veneris提取物中植物素的含量,包括生物碱、黄酮、多酚和单宁。使用2,2-二苯基-1-苦肼基(DPPH)测定抗氧化活性;同时通过铁还原/抗氧化能力(FRAP)测定还原能力;使用琼脂扩散测定法评价对七种细菌和四种真菌菌株的抗微生物活性。同时,对脲酶、磷酸二酯酶-Ⅰ和过氧化氢酶-Ⅱ进行酶抑制研究。结论:沙门氏菌显示出适度的抗自由基活性;羟基自由基的潜能降至初始值的20%左右。S.pectenveneris多种提取物的抗氧化活性与总酚含量呈线性相关。S.pecten-veneris叶对金黄色葡萄球菌表现出最高的抑制活性;对白色念珠菌表现出到最高的抗真菌活性。植物提取物对脲酶的活性最有效;对磷酸二酯酶-Ⅰ和碳酸酐酶-Ⅱ显示出中等活性。结果表明,S.pecten-veneris具有良好的药用潜力,可用于治疗一些特定的疾病。 相似文献

In the context of CAI, the authors present examples of didactic software or‘teachware» developed in a school of engineering, accompanied by a discussion of pedagogical and systems considerations. The 'pedagogical environment' is described as the interface (Apple-Macintosh) used in the teachware in particular in relation to Bloom's six levels of learning. The ‘system approach’emphasises each step and the proper sequence that are necessary to arrive at empirically validated and relevant software. The importance of the new information technologies for both the pedagogue and ‘the media conceptualiser’ are underlined. 相似文献

Following a review of equity issues in testing, especially in relation to science, two assessment programmes in school science, each of which was designed both to probe a range of aspects of student performance and for use in a large-scale study, are discussed. Both have been developed and used in the 1990s, one in Australia only and the other in many countries. The programmes and the range of aspects they attempt to assess are described and results are cited for several groups of students. Issues of fairness through the broadening of large-scale assessments to include tasks requiring students to construct their answers or carry out investigations are addressed as the second focus of the paper. 相似文献
