| Currently,as the development of the new era continues to progress,educational reforms are placing higher demands on teaching.Chemistry is a practical subject,which is one of the foundations of the rapid development of natural science,and among them,“amount of substance” is an important content in the learning stage of high school chemistry,which is significant to the development of student’s core literacy in chemistry.How to improve the effectiveness of teaching “amount of substance” is a topic that educators have been studying.This dissertation is a study on the effective teaching of “amount of substance” in high school chemistry classrooms.The thesis is divided into six chapters,as follows.Chapter 1,with the help of the literature research method,compares the current situation of effective teaching and “amount of substance” classroom effectiveness teaching research,and then clarifies the purpose,meaning and method,research content,and ideas of this thesis.Chapter 2 is the theoretical basis of classroom effectiveness teaching.Through the survey research method and observation method,chapter 3investigated and analyzed the situation of high school chemistry classroom effectiveness teaching.In Chapter 3,this dissertation investigated and analyzed the effectiveness of teaching situations in high school chemistry classrooms through research and observation methods.Chapter 4 designed and practiced the effective teaching of “amount of substance”,based on the theory of effective teaching,the characteristics of effective teaching,and the characteristics of chemistry classroom teaching and the characteristics of students.Through research,educational experiment,and observation methods,in chapter 5,this dissertation investigated and analyzed the effective teaching of “amount of substance”.Chapter 6 is the summary and outlook of the whole text.Through this research,the following conclusions were drawn.1.Under the guidance of effective teaching theory,designing diversified classroom activities,creating chemistry learning situations,and exerting the power of role models can promote student’s learning experience on the topic of “amount of substance”,increase student’s participation and learning motivation,change some student’s attitudes toward learning chemistry,and make them enjoy learning.2.Under the guidance of effective teaching theory,by strengthening student’s macro and micro integration,guiding them to form scientific inquiry thinking,and improving their chemical understanding,it can help students change their way of learning chemistry and help them build an “amount of substance” chemical knowledge system.3.The design of effective teaching is not only applicable to the teaching of “amount of substance”,but also has a positive impact on the teaching and learning of other contents. |
