Development And Application Of PBL Chemistry Microteaching Lessons

Microteaching is one of the most required subjects for normal students.However,there have not been many changes in the mode of development for many years.Through in-depth chemistry micro-grid teaching in colleges and universities,we find that in the process of micro-grid teaching,the training of the normal students'teaching skills is often only emphasized,while the training of educational theories is neglected.Students may feel that the combination of theory and practice is not enough and even some students will learn Part of the subjects useless error awareness.Some students in the micro-teaching links to copy the contents of the Internet,the lack of subjective initiative.The PBL question-based learning model inspires students'problem awareness by creating real situations and designing problems,learns the answers through the group cooperative learning and explores students'enthusiasm for learning,and in this process,Pedagogy,psychology and other aspects of micro-grid chemistry teaching better integration,to promote normal students through independent thinking,group cooperation to solve the problem,access to problem-solving skills to enhance and promote the transformation of learning styles.Based on the investigation of the existing problems in the teaching of micro-grid chemistry,this paper analyzes the development of PBL-based problem-based learning and micro-grid teaching both at home and abroad,introduces PBL problem-based learning model into the teaching of micro-grid chemistry,PBL learning model problem situation design,case development,implementation and learning effectiveness were studied.
