只有在学习那些“半生不熟”“似懂非懂”“似会非会”的东西时,学生才感兴趣而迫切希望掌握它。因此能否成为问题情境,主要看学习任务与学生已有知识经验的适合度如何,只有在既适应又不适应(中等难度)的情况下,才能构成问题情境。
Students are only interested in learning “hard-to-learn” and “nonsense” if they learn something like “half-baked”. Therefore, whether it can become a problem situation depends mainly on how well the learning tasks fit into the students’ existing knowledge experiences, and can only form a problem situation only if they are both adapted and unsuitable (moderately difficult).
