Research On Problem-based Teaching Instructional Design And Practical In Junior High School Mathematics

In the new period,what our country needs is creative and critical talents.These talents need to be highly sensitive to problems.The traditional teaching mode can't satisfy the needs of the era,so the education reform is of great urgency.Educational goals include the cultivation of problem-solving abilities.Everything discussed in teaching revolves around finding and solving problems.The emerging problem-based teaching takes the problem as the core,which is the only way to cultivate students' ability of solving practical problems.So the research on Problem-based Teaching instructional design and practical in junior high school mathematics are proposed in line with the current research situation in our country.The purpose is to explore a teaching method that is more conductive to student's development and ability cultivation.This article has carried out problem-based instructional design and practical research on Grade 4(experimental)and Grade 10(control)of an middle school in Changsha.The author provides specific research cases.Through our research,it is found that Problem-based teaching is a new teaching method adapted to the development of modern society.The class with students as the main body,the problem as the carrier,teacher cooperate with student to explore knowledge is what students truly need,which can improve class efficiency and teaching effectiveness.The thesis is divided into five parts.The first part introduces the research background,content,significance and methods of this article.The second part is the research review.First,the connotation and characteristics of problem-based teaching are defined and described.Then it discusses domestic and abroad current status of problem-based teaching research.Finally,the related theories ofproblem-based teaching are elaborated in detail to pave the way for future research.The third part of the thesis analyzing the current situation of problem-based teaching at first.And showing the junior middle school mathematics problem-based teaching in the eyes of students and teachers.The fourth part is the specific practice of problem-based teaching instructional design.First,it shows the instructional design for the first attempt of problem-based teaching instruction design.After reflection,we will set the experimental class and the control class to start the experiment,taking Chapter 12?Congruent Triangle?in the eighth grade of the human education edition as the learning content.This paper provides three cases of problem-based instruction teaching design for different types of courses,and compares and summarizes the experimental results.In the fifth part of,based on the reflection and summary of the experimental results,providing some reasonable teaching suggestions to the teacher,and pave the way for the follow-up study of problem-based teaching research.
