基于“几何画板”的中学数学课堂“探究学习”的实践与探索

Practicing about “Inquiry Learning” Using the Geometer’s Sketchpad in the Mathematics Classroom

几何画板”应用于中学数学课堂“探究学习”中,解决了“探究学习”的难点问题。创设一个以“学”为中心的“探究学习”情境,其具体操作程序主要包括五个环节:问题情境,探究实验,表达交流,归纳猜想,分析验证。实验表明:学生学习数学的兴趣明显增加;对数学知识理解水平、数学技能掌握水平、应用数学知识和技能解决问题能力有所提高;初步养成了良好的学习数学的态度与习惯。

The Geometer's Sketchpad resolved the difficult problem in 'inquiry learning', which is to establish the situation of student-centred learning, in the mathematics classroom. The model of teaching includes five processes: problem situation; inquiry experiment; expression and exchange; induction and guess; analysis and testing. The experiment shows that the students obviously increase in the mathematic learning interests; have the exaltation in level of comprehending mathematic knowledge, level of controlling mathematic technical ability, ability of solving problem with mathematic knowledge and technical ability; cultivate the attitude and the habit of good study mathematics.
