Study On The Mathematical Situatioal Instruction Model In Junior High School Baced On Problem Learning

Technology and social progress in 21st century put new requirements for education, but the current state of mathematics teaching is not optimistic. Students don't like math and are not active in math's class.When they talk abou maths, it just makes them feel bad,they take maths as their "nightmare". New curriculum reform calls upon us to re-examine the content of mathematics teaching and make it be able to link to the real life of students. As educators,we need to give students not only knowledge,but also more experience, activity, innovative thinking and math learning experience.Now teachers are faced with this problem, they tried to change the current situation, they used many ways and means in their class,like situational teaching, to explore of learning etc, but because of lack of theoretical guidance. Acording this research,we try to give their theoretical guidance, that is what the main idea in this paper.In this paper, the current situation of teaching model is took as a research object, we investigate and research the current situation of teachers in understanding of the operation status and the difficulties in the practical application in situation teaching.According to the survey, it can be found that teachers teaching in the situation that there lack of scientific context to mathematical misunderstanding and lack of effectiveness, and conduct attribution analysis. On this basis, build problem-based learning mathematics situations teaching in junior high school, through experimental validation, given findings of the study.This article is divided into six parts, each part of the main contents are:Partâ… :Introduction. It's about research design, ideas,meaning in problem-based learning and situational teaching and the discuss of the theory for review of relevant research at home and abroad to introduce the theoretical foundation.Partâ…¡:The investigation of status of implementation of situational teaching model.First, we selected 80 teachers from 6 middle schools randomly to conduct a questionnaire survey and interviewed with individual teachers, simultaneously go to schools to listen to their lessons. Through observation and conversations with teachers, get first-hand information. The errors of teaching on the current situation of were classified analysis and attribution analysis, through analysis that the main reason is the lack of problems, it raised the issue of learning based teaching model mathematical situations.Partâ…¢:An issue-based learning mathematics situations teaching model construction.First, analies the correlation about problem-based learning and situational teaching,and then gives the model the basic framework and sample lesson examples.Partâ…£:The experiments about the mathematical problem-based learning situation model. The experimental results show that the model for improving math achievement, and promoting interest in mathematics learning.Partâ…¤:Conclusions.1.The model can improve the effectiveness of mathematics teaching significantly.Experimental results show that the creation of good situation teaching teaching in mathematics, to a certain extent, improve their grasp of mathematical knowledge and mathematical ability.2. With this teaching model,students'interest in mathematics has been changed.The experiment has increased the students interest in learning mathematics and aroused the enthusiasm of students to learn mathematics. 3. The enthusiasm of students to participate in teaching activities has been increased.Through the creation of problem-based learning situations, the enthusiasm of students to participate in teaching activities has increased, interest gradually thicken, reducing the teacher explained, to obtain a better teaching results. In the learning process, students not only to think on their own initiatively,but also to explore research questions actively, and gradually chang the phenomenon that teachers "carried away", the students gradually become masters of learning.4. The evaluation about teachers which from students has been changed.Problem-based learning teaching model of the implementation of context, to stimulate interest in learning so that students in math activities to produce good emotional experience, and promote dialogue with teachers and students, thus gradually changing the role of teachers, then recognized by students.
