实验在生物学科中具有重要地位。教师应充分利用实验课培养学生的自主探究能力和创新能力。探究性实验不应只强调实验结果,而应更注重探究的过程。以谈话和讨论为主的启发式教学模式可以一系列具有思考价值的问题串的形式展开。本文结合与酵母菌相关的两节实验课例,浅谈“问题-启发”式教学在高中生物实验探究课上的有效应用。 Experiments in biology have an important position. Teachers should make full use of experimental lessons to cultivate students’ ability of self-exploration and innovation. Exploratory experiments should not only emphasize the experimental results, but should pay more attention to the process of inquiry. The heuristic teaching model based on conversation and discussion can be expanded in the form of a string of questionable values.
