Electrolytic Cell Based Anchored Instruction, Teaching Design Research And Practice

Research has shown that many high school graduates who has study chemistry for four years can not learn with their knowledge of chemistry to link the use of chemical knowledge and solve their practical problems. The construction principle comes to anchor the type teaching strategy emphasis to draw the real problems into introduction classroom, under teacher's guidance, students analyze the question which they meet at present, reorganize a knowledge detailed list which these questions need, and solve the problems independently. The method is helpful for enhancing students'ability to solve the actual problems. The electrolyzer knowledge is a carrier of the research. The utilization comes to anchored teaching strategy, carries on teaching design, and implements in the high school classroom. The use of come to anchored teaching strategy in real classroom instruction is for the purpose of sharpening students'question solution ability. The thesis includes five parts altogether. Of which the main content is as follows:Part one, proposition of the question. Expound the reason of selecting the title, make a summary analysis about electrolyzer, point out its important position in high school chemistry study. In the consult literature and practice interview's foundation, summarize the present situation that the student study electrolyzer knowledge, and analyze the reason.Part two, Theoretical foundation of the research. Carrieson the induction regarding the domestic and foreign teaching design model to summarize, proposes the own teaching design basic link. Elaborated comes to anchor the type teaching strategy implication, the basic link, the goal and with the merit. Carrie on the domestic and foreign teaching design model, propose the own teaching design basic link. Elaborated comes to anchor the type teaching strategy's implication, the basic link, the goal and the merit.Part three, theory conception. Under the construction principle theory's instruction, carry on the analysis of the teaching design that based on come to anchor type.Part four, teaching design and implement. Under the above theory's instruction, carries on the teaching design and to the electrolyzer this concrete knowledge spot implements in the high school classroom.Part five, Research reconsideration and forecast.The practice proof: The use of comes to anchored teaching strategy is advantageous in the understanding and grasps of"the electrolyzer"Students' study initiative and the ability of question solve enhance. Participate in the classroom positively, question solution ability obtain the development.
