“发现法”是美国著名教育家布鲁纳倡导的一种教学方法。运用“发现法”进行教学能充分发挥学生主体作用和个性,激发学生学习积极性。笔者以初三物理“电流的效应”一课的教学为例谈怎样引导学生在探索中求知,在求知中探索。首先简要介绍与“电流的效应”有关的三件学具。 1.简易电热器取10×8×1cm~3干木板一块,将一段电热丝用两根粗铁丝支架在干木板上如图1。 The “discovery method” is a teaching method advocated by the famous American educator Bruner. The use of “discovery method” for teaching can give full play to the student’s main role and personality and stimulate students’ enthusiasm for learning. The author takes the teaching of the third class physics “effect of electric current” as an example to discuss how to guide students to seek knowledge in exploration and explore in seeking knowledge. First, three teaching tools related to “effect of electric current” are briefly introduced. 1. Simple electric heater takes 10×8×1cm~3 pieces of dry wood board, and a section of electric heating wire uses two thick wire brackets on dry wooden board as shown in Fig.1.
