目前,自主探索的学习方式已被广大数学教师认可,并已广泛运用到课堂教学中。然而,在实际教学中我们发现,有时运用这种学习方式的教学效果与我们的预想相去甚远,究其原因应该是多方面的:比如教师的指导不当,学生的自主学习能力不强,探究方法欠缺等等。我觉得没有营造一个良好的学习情境有时也是一个重要原因。实践证明,创设恰 At present, the way of independent exploration has been approved by the majority of mathematics teachers and has been widely used in classroom teaching. However, in the actual teaching, we find that sometimes the teaching effect of using this learning method is far from our expectation. The reason should be multifaceted: for example, teachers ’improper guidance, students’ self-learning ability is not strong, Wrong method, and so on.
