Investigation On Instructional Design Of Mechanics In Junior School Based On PBL

PBL(Problem-Based Leaming)teaching approach known as problem-based teaching mode was put froward and defined by Barrows as:learning procedure for learners to understand and solve a problems.The aim of this passage is to effectively combine the PBL teaching approach with teaching design,to develop the ability of scientific thinking and the ability of solving practical issues and to cultivate the awareness of innovation and spirit of cooperation.Moreover students are able to deal with questions by cooperation and gaining the knowledge hidden behind all questions.PBL teaching model originated from medical science,aiming to further combine the teaching theory with practice in medical science.Later,the approach was introduced in education field.Based on the background that related to curriculum reform and current situation of Physics Teaching,the passage described the necessity of combing PBL model with Physics teaching design in secondary school.What's more,the teaching design was interpreted from different perspective.Integrating the concept of curriculum reform,the purpose is to enhance the problem awareness of students,to stimulate the leaning interest of students,to improve the learning initiative of students and foster the scientific thinking of students.In chapter three of this passage,with the help of theoretical analysis of PBL model,the correlation and difference between questions especially questions in Physics and problem-based teaching.Then the author further explained the influenced of questions in Physics to students' learning,showing that the problem-based teaching is helpful to the cognitive thinking ability of students.Based on the theoretical analysis,the relevant questionnaire was designed and education practice was carried out.As the result showed,most of students were willing to participate in the class communication to learn new knowledge in problem solving process.Thus two sections of Force and Elasticity were chosen in accordance with the research conclusion and practical situation.In the end,the result of the practice was examined by questionnaire,scale and interviews from students.After the practical examination,it is known that PBL teaching model is effective in transforming the students' learning pattern,stimulating students' learning interest.Thus this research has provided various ways of specific case study and there is a hope that more topics can be discussed in future researches.
