Application Of Elaboration Theory In High School Chemistry

Elabortion theory was founded by an internationally renowned instructional design specialist Reigeluth. Elaboration is the content of the teaching model of the progressive refinement of the structure. Elabortion theory for teaching and learning at the macro level of the four kinds of organizational strategy:Selection, Sequencing, Synthesing, Summarizing, referred to as 4S. While the subject is divided into conceptual content, procedural content and theoretical content.Most literature shows that refined theory mainly used in computers, mathematics and other logical areas of very little literature related to refined theory in chemistry teaching, so I choose this subject can be designed to explore the use of a new theory in chemistry teaching.In my study, "Ion reaction in aqueous solution" content as the starting point, the refined theory applied in high school chemistry teaching, try to use refined theory to deal with different types of subject knowledge, instructional design, classroom teaching, student ability in after comparing refined improvement in the establishment of the whole to the part of the macro-learning framework. This study includes the following:1. On the Elabortion theory of the content and the principles of refined methods for detailed exploration.2. The use of refined theory to deal with different types of knowledge, teaching design and classroom teaching.3. The use of Elabortion theory test after experimental results obtained.4. Elabortion Theory Applied to the Teaching Experiments.In this study the writer will be obtained in experimental data and observations as a basis for analysis. Subjects were guided by teachers in the classroom, the application of refined teaching, unit test scores were significantly improved, especially in the comprehensive analysis of the subject increased significantly. This shows that the Elabortion theory in the teaching effectiveness was significantly higher than traditional teaching methods can make a comprehensive analysis of the students' ability to have more significant improvement.Elabortion theories of applications result in poor health significantly. Analysis of student papers on the problem-solving process, the key is the poor students in learning knowledge and the obstacles, their understanding and memory is very different, and understanding more difficult to obtain and maintain a relatively easy; and remember quite the opposite. Because the understanding of the key players is to make new knowledge and prior knowledge of the appropriate associate, while the refined teaching can help them cross this barrier. An outstanding student of knowledge barriers associated with basically non-existent, which precisely illustrates the refining teaching to improve on the outstanding student less obvious reasons.Juanmian answer from the process of situation analysis and control classes to learn knowledge is fragmented, old and new knowledge is not inherently related information capacity is relatively small. That is the traditional teaching methods of knowledge transfer on the past are better, but the knowledge transfer on the weak far, can not even move. Study is characterized by the refined classes can learn from the past knowledge and experience of living together, expanding the knowledge capacity, and can actively take the initiative to a combination of new knowledge, new knowledge synergy and integration. This will provide a learner's knowledge of the construction of a broader system, it is more useful knowledge; integration and answers to your questions.
