A Study On The Problem Of Primary Chemistry Problem For Senior Middle School Students

The original chemical problem which is objectively existent in nature, social production and life can reflect the concept of science, nature and law is a typical and unprocessed scientific fact and phenomenon. The original chemical problem is full of infotainment, enjoyment, inspiring and openness and applicable to students’age characteristics and psychological characteristics which can stimulate and sustain the interest and curiosity of students, and can be conducive to enhance students’ability in asking questions, solving problems. In order to know the difference between different types of students in the process of solving the original chemical problems and provide valuable advice and guidance for teaching practice, we select the senior high students who have just finished the study of chemical module as research object.At first, we review literature about the original chemical problem and introduce the research results of the concept, nature, characteristics and other aspects of the original chemical problems in the theories, we also define the difference and relation between the original chemical problems and chemistry exercises, describe the educational value of the original chemical problems and provide the operational definition of important terms used in this study.Secondly, we prepare the test paper deriving from the original chemical problems of real-life and production (a combination of compulsory 1 and compulsory 2) and combine with relational-presentation complexity model to analyze the complexity of the problem, and then, we measure and analyze these first grade students’characteristic differences in solving the original chemical problem, and also try to explore the reasons for differences and its influencing factors. The conclusion is as follows:there is a significant difference in the breadth and depth between different types of students in solving the original chemical problem, due to the factors of their knowledge structure, learning interest and others that may cause the differences in solving original chemical problem.
