Research On High School Chemical Formative Exercises Based On Subject Literacy

The high school chemistry exercises is an important tool for us to learn chemistry,and also an important part of the training of students’ subject literacy.The chemical formation exercises is a kind of high school chemistry exercises.Combining with students’ development situation,the students’ subject literacy is based on the selection,adaptation and preparation of the exercises,the number of the usual questions,and the choice of the exercises that suits the students’ difficulty.Students are relieved of their burdens that they gain a sense of accomplishment from the learning questions,enhance their interest in learning chemistry,give feedback on students’ conditions,improve their teaching,and promote their development.In the first chapter,literature review is used to collate the research questions and subject literacy literatures.The trend of chemical education development is briefly analyzed.The purpose and significance of the research are summarized,and the research methods are determined.The second chapter defines related concepts,such as the concept of exercise problems,the formative exercises and the concept of subject literacy,and then studies the relevant theoretical basis,such as Zone of proximal development,the formative evaluation theory,etc.The third chapter,based on the relevant theoretical basis of the previous chapter,introduces the five principles of formative exercises,which are: objective principle,scientific principle,situational principle,hierarchical principle,open principle,and with the guidance of relevant principles to ensure the quality of chemical exercises.Then the functions of the chemical formative exercises are clarifies: Education pointing to function,diagnosis of learning difficulties,consolidating and transferring knowledge,encouraging active learning,promoting knowledge transformation,and putting forward specific formulation strategies of chemical formative exercises according to the principles and functions of chemical formative exercises.Finally,an example is given to illustrate the discipline accomplishment embodied in formative exercises.The fourth chapter is the practice and case analysis of chemical formative exercises.Students learn to train students in chemical formative exercises and listen to students’ and teachers’ evaluation of chemical formative exercises to see if they have a certain influence on students.The fifth chapter draws the conclusion of this study through the above research.Chemical formation exercises have a certain positive impact on cultivating students’ literacy and improve their interest in learning chemistry and their awareness of applying chemical knowledge in life.The insufficiency of research and the outlook for the future hopes to give some help to teaching.
