Research On Obstacles Of Junior High School Students In Solving Inquiry Problems In Chemical Experiments

An important part of junior high school chemistry experiment curriculum is not only junior high school chemistry,but also an important way to learn and understand students junior high school chemistry and an important scientific research level of junior high school chemistry.In the middle school chemistry examination,the exploratory experiment question of chemistry is not only the key question,but also the question that the students find the hardest to answer.Although elearning has received more and more attention in the past two decades with the reform of junior high school chemistry curriculum,there is still much work to be done to improve junior high school students' ability to solve elearning problems.The investigation of junior middle school,the influence of chemical factors,the analysis of the influence of problem solving,the study of chemical experiment junior middle school students' ability analysis,the problem solving ability of junior middle school chemical experiment teaching strategy,deepening the reform of senior high school chemistry to improve the quality of chemical secondary education has important theoretical and practical significance.Based on the theoretical analysis method,this study proposed the possible types of obstacles for junior high school students to solve chemical experiment exploration problems.According to classroom requirements,teaching subjects and the requirements of the chemistry secondary education examination,this paper is prepared for middle school students to solve the problem of exploring chemical experiments.Through the analysis of test results,test and modify the preset types of obstacles in solving the chemical experiment exploration problems of junior high school students,and analyze the influencing factors.The results showed that the junior high school students had some obstacles in solving the chemical experiment inquiry problems,such as "acquiring and processing information,extracting and applying knowledge,disciplinary thinking and overcoming difficulties",and the obstacles were mainly related to the degree of knowledge structure,the level of disciplinary thinking,the learning style and other factorsThrough the barriers of the junior high school students solve the problem of chemical experiment to explore the influence factors analysis,put forward to improve students'experiment to explore the problem-solving teaching advice:let the students in the experimental inquiry learning in chemistry,let the student study chemistry in situational problem solving,motivating students to learn,through the evaluation to enhance students'self-confidence and so on.
