问题驱动理念下阿基米德原理教学设计

Teaching Design on Archimedes Principle Based on Issue-driven Idea

问题驱动教学方法是实践建构主义认知理论的重要方法之一,对激发学生学习兴趣、培养主动学习能力具有重要意义.阿基米德原理是初中物理教学中的重点和难点,学习过程中需涉及到二力平衡、压强和密度等知识,而这些不同水平知识技能的结合往往会导致学生难学易错.为了更好地去探索阿基米德原理及其实验设计与操作过程,将问题驱动教学方法应用在阿基米德原理课程的教学中,对阿基米德原理进行新的教学编排,把抽象的知识点具体化以便于学生更好地学习与理解,最后结合问题驱动理念完成了本节课的教学设计.

Problem-based learning,one of the important methods to practice the cognitive theory of Constructivism,is of great significance to arousing interest in learning and cultivation the ability of autonomous learning.Archimedes principle is the key and difficult point in physics teaching of middle school due to the use of a lot of knowledge such as force balance,pressure,density and so on,which makes it difficult for students to learn and make mistakes easily.In order to explore the Archimedes principle as well as its experimental design and operation process,in this article,the problem-based learning is applied in the teaching of Archimedes principle.Make the abstract knowledge point concrete by a new teaching arrangement for Archimedes principle.
