PBL教学方法在物理化学课程教学中的应用探索——以热力学第一定律教学为例

Application of PBL Teaching Method in Physical Chemistry Teaching-Taking the Teaching of the First Law of Thermodynamics as an Example

随着基础科学的快速发展,传统的以教师讲授为主的授课方式已经不能很好地满足教师和学生的需求。为了更好地适应新发展趋势,提升教学质量,教师需要在教学过程中引进更为先进的教学方法。PBL教学方法是以问题为导向的新式教学法,它以学生为中心,可以提高学生在课程中的参与度,使其在课程中思维更加活跃,同时提高学生学习的主动性和目标性,做到有的放矢,激发学生的学习乐趣。本文以物理化学课程教学中热力学第一定律和热力学第二定律的“克劳修斯表述”教学为例,将教学目标和实际应用结合起来,阐述PBL教学方法的模式及优缺点。实践表明,PBL教学法降低了热力学第一定律和克劳修斯表述的理解难度,既便于学生理解和接受,也能激发学生的学习乐趣,使枯燥的课堂氛围变得更加生动有趣。

With the rapid development of basic science,the traditional teaching method,which mainly relies on teacher lectures,cannot meet the needs of both teachers and students effectively.In order to adapt to the new trends and improve the quality of teaching,it is necessary to introduce more advanced teaching methods.Problem-Based Learning(PBL)is a student-centered teaching approach that is problem-oriented.It enhances students’engagement in the curriculum,stimulates active thinking,and promotes students’initiative and goal-oriented learning.It enables targeted learning,activates students’thinking,and ignites their interest in learning.This article takes the teaching of the first and second laws of thermodynamics,specifically Clausius’statement,in the“Physical Chemistry”course as an example.By combining teaching objectives with practical applications,it elaborates on the mode and pros and cons of PBL teaching method.Practice has shown that PBL reduces the difficulty of understanding the first law of thermodynamics and Clausius’statement,making it easier for students to comprehend and accept.It also stimulates students’interest in learning,making the classroom atmosphere more lively and interesting.
