Teaching Strategies Of Using Original Problems In Physics Review In Senior Middle School

Physics review in high school usually has three rounds.The first round is chapter review;the second round is the subject review;the third round is set of training.This study explores the teaching stra tegies of using the original problem in the subject review of the force and movement,combining with the characteristics of the original problem,the content of the subject and students' review of the first round.Based on the research of relevant literatures at home and abroad,this paper defined the original problems and teaching strategies involved in this study and analyzed the research results and existing problems of the force and movement.It was based on Piaget's Two-way Constructivist Learning Theory,Gagne's Information Processing Teaching Theory and Pragmatism Education Theory.It used the literature and case analysis method to explore to use the original problem of teaching strategies in the subject review of the force and movement.It including the original problem-centered exploration strategy,exercise strategy which was adding the original problem in the exercises and the induction communication strategy which was based on the exchanging of original issues.It was in practice in a high school of a county in Gansu Province.The research showed that problem-centered exploration strategy was applicable to the students' knowledge of confusion and error.It could get students away from exercises and stimulate their learning interests.It also help students to construct the correct knowledge system in the process of their inquiry,but it should pay attention to the influence of the students' levels and their life experience on the original problem when it was used.Exercise strategy was suitable for some knowledge points that were different from students' memory.Adding the original problem in the exercises,it could avoid students rote,be targeted training the review content and standardize the students' answer habits,but teachers should fully understand the students when it was used.The induction communication strategy was appropriate for the regular review contents which have less knowledge points.Students summarized the knowledge pre-class and exchanged the original subject in class.It could lessen students' dependence on teachers.It also could train students' abilities to extract information,but it should pay attention to select the appropriate contents and original questions.Finally,the paper put forward teaching suggestions.The selected original question was related to the force and movement in the question-inquiry strategy.The teacher guided students patiently to transform the original problem into the physical problem of the force and movement.Students tried a variety of solutions.The exercise strategy selected targeted exercises of the force and movement included the original question.The problem-solving process of all questions should be presented.The teacher needed to communicate with students timely to make the relevant adjustments.For the induction communication strategy,it should encourage backward students to summary the contents of the force and movement.The teacher needed to present the knowledge system on the blackboard.
