基于“开放教学”的金相技能实验课改革研究

Research on the Reform of Metallographic Skill Experiment Course Based on the“Open Teaching”

该文从金相技能实验教学特点、实验课程对师生的要求以及传统金相技能教学实验课程存在的问题出发,结合本科教学实验条件,以"开放教学"为出发点,通过设立开放实验项目的途径来建立该实验课的弹性教学机制,探索金相开放实验课与金相大赛的有机联系,实现"教赛并进",利用大赛成果实现"以赛促教"。有效翻转课堂,使学生成为上课的主人,激发学生学习主动性,显著改善金相技能实验课程的教学效果,确保每位学生真正掌握金相制样技能这一最终教学目标得以实现,从而进一步形成"大赛""教学""科研"三者的良性循环。

Given the characteristics of the experiment teaching, the requirements for teachers and students, and the problems of traditional metallographic skill experiment course and the experiment conditions of undergraduate teaching, this paper establishes a flexible teaching mechanism by the introduction of open experiment project, during which "open teaching" acts as the starting point.The purpose is to explore the connection between the open metallography experiment course and the metallographic contest, promote teaching and contest going hand in hand, and boost teaching by contest results. Flipped classroom is effectively used to stimulate students’ initiative in learning through increasing their control of class, remarkably improve teaching effect of metallographic skill experiment course, and realize the teaching goal of every student’s proficiency in metallographic skill, thereby forming a virtuous circle of "contest", "teaching" and "scientific research".
