Research On The Effectiveness Of Algebra Teaching In Junior Middle School Under PBL Mode

Junior high school mathematics is divided into four fields: number and algebra,figure and geometry,probability and statistics,synthesis and practice.Number and algebra are one of the core contents of junior high school mathematics.Therefore,many teachers pay attention to the research on algebra teaching.This paper finds that algebra is not as intuitive as geometry because of its complexity and abstraction.Students are easy to lose interest in knowledge itself.In the aspect of teachers,many teachers will also have their own teaching methods and consciously adopt problem-based teaching,but lack of systematic theory guidance.In practical teaching,students lack of sufficient Time and opportunity to think about problems.The theory of problem based learning is derived from the problem based learning method abroad,or PBL.The content of this paper is to study the effectiveness of Algebra Teaching in junior high school based on PBL model.The whole text is divided into seven chapters.The first chapter is the introduction,which mainly explains the origin,problems and significance of the research topic,as well as the research ideas and methods;the second chapter describes the research summary of this paper through literature research,including the definition of concept,theoretical basis and the summary of domestic and foreign research;the third chapter uses questionnaire and interview to investigate the current learning status of junior middle school algebra;chapter four is in the previous research On the basis of the research,the author tries to construct the content of teaching design in PBL mode from the aspects of teaching objectives,problems,teaching evaluation and process,and gives two teaching cases.According to the problems in practice,the revised teaching process is given;chapter five,before the experimental research,the validity standard of Algebra Teaching in junior high school is formulated;chapter six is about the initial stage of PBL mode The effectiveness of Algebra Teaching in China is mainly used classroom observation,comparative experiment and questionnaire survey to analyze the learning situation of the students in the two classes.Finally,the paper is given the conclusion and reflection in Chapter 7.The research conclusion of this paper is as follows: first,PBL mode needs to be enriched and perfected in the field of basic education;second,PBL mode should be combined with traditional teaching,which can help improve teaching quality;third,in PBL mode,teachers and students' classroom performance is better than traditional classroom performance;fourth,classroom teaching under PBL mode stimulates students' interest in learning and promotes sustainable development;fifth,it is to improve teaching quality;fourth,classroom teaching under PBL mode stimulates students' interest in learning and promotes sustainable development;fifth,improve teaching quality The sixth is to improve the students' ability to solve problems;the seventh is that the algebra teaching in junior high school is effective for students' achievement improvement under PBL mode.
