“算法与程序设计”选修模块一直以来都是一门难教、难学的课。本文通过同课异构的多轮教学实践与反思,对“问题解决教学法”的问题选择策略进行了初步探析,提出了从“寻找学生新旧知识的衔接点”“把握学生学习的兴趣点”“批判性地取舍教材实例”三个方面选择问题的策略。实践证明,遵循以上策略选择的问题可以提高学生的课堂积极性,培养学生运用算法与程序设计解决问题的能力。
“Algorithm and Programming ” Elective module has always been a difficult to teach, difficult to learn class. Through the heterogeneous multi-round teaching practice and reflection in the same class, this paper conducts a preliminary analysis of the problem selection strategy of “problem-solving teaching method”, and puts forward that from the point of “finding the connection point between old and new knowledge of students” Learning points of interest “” Critically choose the teaching material examples "three aspects of the strategy of choice. Practice has proved that follow the above strategy to choose the problem can improve the students’ enthusiasm in the classroom, training students to use algorithms and programming skills to solve the problem.
