The Practical Research Of Exploring Chemistry Teaching In Junior Middle School Based On The Promotion Of Key Competences

With the impact of the international environment in recent years,as well as the promotion of the curriculum reform in China's mid-term examination,the way of mechanical memory and reinforcement training can not keep up with the latest teaching needs.In the field of junior middle school chemistry education,the voice of improving learners' key competences is getting higher and higher.The latest teaching reform direction of junior middle school chemistry is to improve students' key competences of chemistry,and carrying out inquiry experiment teaching is the key.Experiencing the process of scientific inquiry is conducive to the healthy development of students' physical and mental health,and helps students develop their ability of continuous learning and the improvement of their achievement in mid-term examination.Improving the experimental teaching,especially the inquiry experiment teaching,is the catalyst to promote the chemistry curriculum reform in junior middle school.By absorbing the experience of key competences and exploratory experimental teaching at home and abroad,this study proves that it is feasible and necessary to carry out exploratory experiment teaching in junior high school chemistry teaching from many angles,such as theory and practice.This research mainly focuses on theoretical research,case studies and text analysis.In view of the main content of the junior high school chemistry inquiry teaching,through the questionnaire survey and the individual interview,we can understand the teaching process of the teachers' individual,and then analyze the teaching link of the junior high school chemistry inquiry experiment teaching.In view of the problems in the present situation of the experiment teaching,the teaching practice is gradually practise in the teaching practice,thinking the countermeasures and summarizing the experience,and forming a variety of teaching strategies.According to the results of practical research,the following strategies are put forward for junior high school chemistry inquiry experiment teaching.First,improve the verification experiment to the exploratory experiment.It accords with the law of students' psychological development,and is conducive to the smooth development of teaching.Second,seize the best time to design exploratory experiment.Third,the theory is connected with the reality,and the new knowledge is constructed.It can effectively improve students' knowledge application ability and students' academic achievements.Fourth,create situations,identify problems,and make students' experimental inquiry more interesting and practical.Fifth,choose some links to explore and adapt to the third grade.Highlighting the key points of teaching,simplifying the experimental steps,fully reflecting the effectiveness of inquiry based experimental teaching.The improvement of key competences is inseparable from the joint efforts of society,schools,families and teachers and students.The reform consciousness is the premise,the teaching material is fundamental,the production and life are the source,the emphasis on the double base is the foundation,the process and the method are the key,the opening of the inquiry experiment is the key,the positive emotion is the guarantee.The exploratory experiment teaching must be based on the curriculum standard and the teaching material,combine the teaching situation,integrate the teaching resources,arouse the students' enthusiasm for learning,reflect on the diligent summary,and gradually improve the students' core accomplishment.In this study,two class students were selected as the research samples,which were divided into the experimental group and the control group.The experimental group mainly adopted the exploratory experiment teaching.The experimental teaching was mainly used in the control group.The teaching experiment time was one term.In this study,four standardized tests were conducted on the experimental group and the control group respectively.Through the study,it is found that the implementation of exploratory experimental teaching can not only improve the teaching performance,but also effectively train the students' other key competences,the change of learning attitude,the improvement of learning enthusiasm,the atmosphere of learning collective classes to form a positive trend,the renewal of teachers' educational ideas and the improvement of teachers' business ability.
