Research Of Chemistry Homework Designing On Promoting Concept Construction In High School

The new curriculum reform advocates to promote the development ofstudents for the purpose of improving students’ scientific literacy as the goal,focus on changing view of knowledge. The new high school chemistrycurriculum standards expressed the basic concept of the new chemistrycurriculum, emphasis on the leading role of the basic concepts of chemistry.Training of science concepts is the key to apply their knowledge, but also theneeds of modern society. Concepts of teaching are an important part ofhelping students builds the concept, and assignment is the part of teachingand learning activities. In the existing literature studies of the chemicalhomework, there are no studies about designing chemistry work on promotingthe construction of the concepts. In order to find new methods or ways todevelop students’ basic concepts of chemistry, and further optimize theteaching effectiveness of construction of the concepts, and promote betterdevelopment of students, this study was designed to design works which is topromote the concept of construction, enrich and improve the function andvalue of chemistry works.In this study, there are six parts.The first part is to ask questions, mainly on the need to design theconcept construction work. And this laid the foundation for the purpose andmission of the proposed research.The second part is the literature review, in this part this study focusedon combing the meaning and the basic characteristics of the basic concepts ofchemistry, the formation and development process and developing strategiesand so on.The third part is the purpose and mission.The fourth part is research on designing work to promote the concept ofthe construction in the high school chemistry. On the basis of previousstudies, this study first of all defined to promote the concept of constructionwork and then analyzed the characteristics of the work, promoting designideas of the concept of the construction in chemistry homework. Promote theconcept of the construction work features are integrated, task-driven andsituational. The corresponding work design ideas are to sort out clear theimportant basic concepts of chemical in teaching; to establish contact withthe specific content between the basic concepts; by relevant content to develop a comprehensive task and design thinking-value issues; and finallyto create a suitable driver situation. Both of these two aspects designed thebasic requirements and directions for designing homework cases behind.The fifth is cases design and analysis on promoting the idea of theconstruction of the high school chemistry homework. In this study, the twounits teaching elements of the material world and the elements of nature inthis study used as the research topics, under the guidance of the workcharacteristics and design ideas were designed to study the works.The main content of the research process is to address specific issuesrelated to the implementation of the design work——how to analyze therelationship between the basic concepts and specific knowledge, how to setup driving work tasks, how to design thinking value questions, how to createthe appropriate driving situations and what sources of situation material?Finally, this study also showed a corresponding work cases and case studies.Finally, based on experience gained in the research, this studies alsoanalysis and outlook of the shortcomings of the results.
