探索微积分的概念教学

微积分作为高等数学教学内容的重要组成,其已经得到了广大教师以及学生的高度重视。由于微积分的教学内容往往给人抽象、枯燥之感,学生在学习过程中常常感到头痛。然而,微积分的教学对培养学生的逻辑思维能力以及数形结合思想非常有利,所以,教师在教学过程中,要积极采取各类有效的教学措施,帮助学生提高微积分的学习效果。本文重点探索高等数学中微积分的概念教学。希望能够有助于学生思维能力的提升。     

EUROPEAN DISSERTATION SUMMARIES

To alleviate teachers’ reluctance toward practical work, there has been much discussion on teachers’ pedagogical content knowledge, teaching materials, and failsafe strategies for practical work. Despite these efforts, practical work is still regarded as a challenging task for many elementary science teachers. To understand the complexity of teachers’ conflicts in practical work, this study examines teachers’ ideas about teaching and learning that influence teachers’ decision‐making and action on teaching practical work. More important than knowing technical–rational aspects of practical work is to understand the internal contradictions that teachers have to resolve within themselves regarding their capabilities and beliefs about science teaching and practical work. Using stories and experiences of 38 third‐year university students in a science method course in Korea, we seek to understand the conflicts and negotiations that they experience as they make decisions regarding practical work throughout their course. Reflective writings and group discussions on their lived experiences and concerns were used to probe participants’ ideas on teaching using practical work. From written and verbal data, themes were saturated in terms of the aspects which could (dis)encourage their practice. Results suggest that there are multifactorial challenges in pre‐service teachers’ understandings and concerns in practical work. Besides time, materials, and curriculum, pedagogical assumptions and values also compositely challenge the minds of teachers. As the pre‐service elementary teachers negotiated within themselves the importance of science in classroom and social levels, the question is raised about their identities as pre‐service elementary teachers to appreciate the balance between science teaching and practical work.
