基于PBL的启发式教学方法在离散数学课程中应用探究——以等价关系为例

Exploration on the Application of Heuristic Teaching Method Based on PBL for Discrete Mathematics——Taking the Relation of Equivalence as an Examp

离散数学是计算机相关专业的一门重要基础课程。由于该课程具有理论性强、内容抽象等特点,文章提出使用一种基于PBL(Problem-Based Learning)的启发式教学方法进行教学。文章以等价关系章节为例,PBL教学方法将教学过程分为课前引导、课中指导、课后开导三个阶段,采用引导学生提出问题并以小组讨论的形式解决问题。课后以小组评价表的方式构建一个可持续改进的教学评价体系,用以反馈教学质量。实践证明,该课堂教学方法不仅可以发挥大学生学习的主观能动性,而且有利于大学生创新思维与创新能力的形成与培养。

Discrete mathematics is an important basic course in computer related majors.Due to the strong theoretical nature and abstract content of this course,this paper proposes using a PBL(Problem-Based Learning)heuristic teaching method for teaching.Taking the equivalence relation chapter as an example,this method divides the teaching process into three stages:pre class guidance,in class guidance,and after class enlightenment.It guides students to ask questions and solve problems in the form of group discussion.Afer class,construct a sustainable improvement teaching evaluation system using a group evaluation form to provide feedback on teaching quality.Practice has proven that this classroom teaching method can not only unleash the subjective initiative of college students in learning,but also facilitate the formation and cultivation of their innovative thinking and innovative ability.
