Research On High School Chemistry Experiment Teaching Based On Project-based Learning

With the requirements of quality education in China,the importance of project-based teaching in practical teaching is gradually highlighted.Project based teaching mode is a new teaching mode based on modern constructivist learning theory.It emphasizes the people-oriented and project-centered teaching method.In cultural education,the appropriate use of project-based teaching mode can create a practical application situation related to the teaching content for students to stimulate students' interest in learning,so that students can have a more profound experience,so as to improve learning efficiency.There are many dynamic contents in the heating decomposition unit of high school chemistry curriculum that cannot be presented in the traditional teaching materials,which often leads to serious learning gap of high school students.In view of this,this study specially made a teaching plan of heating decomposition project,hoping to improve the learning effect of students in this unit.The evaluation of students' learning effectiveness is a complex task,which involves the inaccuracy,fuzziness and uncertainty of human decision-making.In order to study the effect of project-based teaching on high school students' learning,this study adopts the project-based chemistry classroom teaching mode.The experimental objects are265 students in two classes of a middle school,and the teaching content is high school chemistry heating decomposition unit.According to the results of statistical analysis,it is found that project-based teaching is easier to improve the learning effect of students with low practical ability.The results of this study can provide reference for other chemistry teachers in project-based chemistry teaching.Teachers should give students appropriate learning guidance according to the individual differences of students' chemical practical ability,so as to improve students' learning effectiveness.
