Study On Teaching Strategy Of Acid Base Salt In View Of Knowledge Classification Theory

Learning of junior high school chemistry in acid,alkali,salt,is learning the difficult and key point for junior middle school students,the more knowledge and more scattered is not easy to remember and use knowledge classification teaching method as a kind of teaching strategy is applied to the teaching of acid,alkali,salt can be messy information information block,and understanding between the contact and easy to remember.In this paper,based on the chemical knowledge classification perspective,combined with psychology and chemistry language habits,the chemical knowledge is divided into two major categories: chemical declarative knowledge and chemical process knowledge.Chemical process knowledge is further divided into four categories,such as intelligent skills,cognitive strategies and experimental operation skills.This paper based on knowledge classification theory of acid,alkali,salt teaching strategy reconstruction.It is considered that to students of different categories of knowledge learning process as the basis,the establishment of acid,alkali,salt teaching ideas to construct and specific teaching methods designed to help to explain the formation of acid,alkali,salt Teaching content system,and focus on the combination of acid,alkali,salt in the teaching of teaching problem to carry on the empirical analysis research,to guide the specific line of teaching work.Is proposed in this paper to do a good job in acid,alkali,salt content of courses on the teaching of modern design needed to meet the basic requirements,and in order to meet the basic requirements of acid,alkali,salt teaching design,in acid,alkali,salt teaching design should pay attention to the implementation of the general principles.Explicitly put forward acid,alkali,salt teaching objectives,by acid,alkali,salt,teaching,teaching method,design of empirical analysis and case study methods,is conducive to the direction of clearing the teaching work of acid,alkali,salt can not only cultivate students explore the spirit and experimental skills,but also make students bears a great intelligence and potential can be fully excavated.Knowledge system and method for making them easy to master the salt and alkali salt.
