一、生成性课程资源的特征1.瞬时性。教学过程中动态生成的课程资源随着物理教学情境的发展而变化,是流动的、瞬时的。教师在教学中要有敏锐的洞察力和随机应变的教学机智,抓住教育契机,及时捕捉、激活和利用这些生成性教学资源。2.非预设性。教学前,动态生成的物理课程资源教师很难去设想、预料。教学时,师生互动过程中它却不时地闪现,教师若不注意,则瞬间流失,所以它往往处于非预设的状态,需要教师具有高度的教学智慧和教学应变能力才能发 First, the characteristics of the generative course resources 1. Transient. The dynamically generated curriculum resources in teaching process change with the development of physics teaching situation, and are mobile and instantaneous. Teachers in teaching have keen insight and adaptable teaching tactics, seize the educational opportunities, timely capture, activate and use of these generative teaching resources. Non-default. Pre-teaching, dynamic generation of physical curriculum resources teachers is difficult to imagine, expected. When teaching, teachers and students interact with it from time to time flash, if teachers do not pay attention, the moment of loss, so it is often in a non-default state, requires teachers with a high degree of teaching wisdom and teaching ability to respond
