The Investigations And Strategies On The Chemistry Exercise Teaching

The chemistry exercise teaching is an essential part of high school chemistry teaching,taking on the responsibility of cultivating students' ability to use their knowledge to solve practical problems,and in the process of solving problems it helps students to accurately understand,absorb and consolidate what they have learned,at the same time,it can also feedback the knowledge of the students to the teachers,laying the foundation for the follow-up teaching work.Efficient exercises can not only help students to strengthen their dual foundations,encourage students to apply what they have learned to solve the practical problems,but also teachers can teach their solution methods,at the same time cultivate students' ability to standardize chemical expressions,improve students'ability to process information,strengthen students' lifelong learning awareness and rigorous realistic scientific attitude,teachers accurately pass on the core literacy of the chemistry discipline to students,thereby to improve teaching efficiency.Aiming at the actual teaching process,teachers often attach great importance to teach the new courses,and are too casual to teach the exercises.This paper aims to understand the status on the chemistry exercise teaching in high school by using questionnaires and interviews.After counting and analyzing the obtained data,targeting the feedback questions,as the principle of creating an effective classroom and cultivating students'chemistry literacy,to explore the teaching strategies of optimizing learning courses,it helps to put the teaching and learning of chemistry into practice,and has a certain guiding significance for creating the efficient classroom of chemistry exercise.This thesis is divided into six chapters altogether:the introduction,the background of the proposed topic,the analysis of the teaching status of the high school study lesson at home and abroad,the purpose and significance of the subject research,and point out the main content and method of research.The second chapter summarizes the content and characteristics of high school chemistry exercise teaching,clarifies its status and function in high school chemistry learning,and summarizes the main modes of teaching high school chemistry teaching.The third chapter,teachers and students are investigated by questionnaires and interviews on the current situation of the chemistry exercise teaching,introduce the process of questionnaire survey,for reaching out rigorous statistics and analysis of the survey results,the present situation of the chemistry exercise teaching in high school is basically understood.The fourth chapter,through in-depth thinking on the analysis of the survey results,points out the problems and draws the reasons.The fifth chapter,from the three aspects of school teachers and students,several strategic methods are proposed to optimize the teaching of chemistry exercise in high school.The sixth chapter,design specific cases from two perspectives of grade 1 and grade 3 in high school.The seventh chapter,conclude with a summary of the important influencing factors on the chemistry exercise teaching in high school and strategies for optimizing the exercise teaching,and finally points out the shortcomings in the research of this topic.
