开放题有多种形式,如条件开放、问题开放、答案开放等。其实,所谓开放就是减少约束,因而给了同学们更大的思考与选择的空间,实质上是降低了难度。关键是:“给你宽松,何必自寻烦恼”。 There are many forms of open questions, such as open conditions, open questions, and open answers. In fact, the so-called opening up is to reduce the constraints, which gives the students greater room for thinking and choice, which in essence reduces the difficulty. The key is: “If you are relaxed, why bother?”
