Study On Theory And Practice Of High School Chemistry Model Teaching

Today,the new high school chemistry curriculum teaching goal is to improve students 'scientific literacy,improve students' observation problems,analyze problems,creative thinking and other capabilities.Among them,in the "general high school chemistry curriculum standard(experiment)" put forward the model teaching and other methods in high school chemistry teaching practice importance.Model teaching has a certain degree of intuition,which can visualize the abstract concepts of chemical structure such as chemical structure in chemistry teaching and transform unknown problems into known problems so that the abstract and image thinking can be effectively combined.At the same time,it is an important way to improve the quality and efficiency of teaching by developing the model teaching based on the students' present level of knowledge and cognitive structure.It can also help students to further discover problems,analyze and solve problems,and expand the network structure of chemical knowledge.This research starts from the study of theory and practice in chemistry teaching model to reflect the significance of model teaching in chemistry teaching design so as to provide reference for teachers 'chemistry teaching and students' scientific literacy training under the new curriculum background.And reference.In this thesis,the theory of model teaching includes an overview of model teaching methods,the theoretical basis of carrying out model teaching methods and different strategies of using models.The practice of model teaching is based on the 2015 grade of Xiangzhou No.1 High School in Xiangyang,Hubei Province.A total of 15 classes in the first year of enrollment within a week for the questionnaire survey found that students in the chemical model construction and application of ubiquitous lack of other gender and pre-admission chemistry also had a significant impact that boys and key students in the construction of(8)and high(9)classes in order to carry out model teaching experiments,of which the high one(8)classes for the experimental class chemistry model teaching,Another class uses traditional model teaching.The results showed that the results of the questionnaire survey at the end of the semester of the chemistry model teaching show that the ability to construct and use the chemistry model is generally improved.At the end of the semester,the students' chemistry scores were significantly higher than those of the traditional teaching.
