Abstract


Since the American psychologist David Ausubel made since the concept of advance organizers, advance organizers on the theoretical and applied research by everyone attention. After a long research, extension and intension advance organizers have been greatly developed; object of study ranging from children to adults to expand; Applications from the original extended to the field of teaching materials prepared by other fields. However, many previous studies mainly focused on the advance organizer for the effective promotion of student learning, and how learning needs based on the rational use of advance organizers relatively little research. Research for this article, focusing on research in the field of chemistry education of different types of advance organizers in chemistry and chemical problem solving Textbook of advance organizers usage. Chemistry study chemistry textbook is the premier student learning resources. This comparative analysis through Britain, America, Hong Kong and mainland China and other countries and regions, some of the chemistry textbook usage of advance organizers found that (1) introducing the concept of time in all kinds of materials used more advance organizer; ( 2) According to the concept of abstract conceptual level and students' learning requirements, various types of materials are used to introduce the concept in different ways, mainly using three methods, namely the introduction of the concept of advance organizers of the upper law, advance organizers for the next bit introducing the concept of law and advance organizers to introduce the concept of comparative law: (3) types of advance organizers in the selection of materials, the characteristics according to the content of knowledge and learning resources, environment and other factors using multiple types of advance organizers, such as text narrative advance organizers, pictures and other type of advance organizers. Previous studies have already shown that the proper use of advance organizers on student learning have a certain role in promoting. However, due to a wide range of advance organizers, the choice of different types, different methods may also exist for students to learn different effects. In this paper, experiments for different types of advance organizers and the same kind of advance organizers in different ways as the students the role of chemistry problem solving differences were studied. Studies show that: (1) the different types of advance organizers in promoting the role of students to solve chemical problems there are differences, such as \\(2) the same type of advance organizers but its presentation is not the same for students to solve chemical problems, there are some differences in the impact. If the organizers of the specific narrative presented directly render more effective than obscure; overall picture presented by type of advance organizers presented the score-step advance organizers to promote better.
