The Research Of Instructional Design Model Of High School Mathematics Based On Constructivist

The basic ideal of the mathematics instructional design based on constructivist mainly are:to emphasize the students as the center, all of the instructional designs focus on how to realize construction of significance. It also puts the function of situation conversation, cooperation and construction of significance on emphasis. Teachers play the role of instruction, help and appraisal.Documentary research method, survey research and case method are adopted in the thesis. Five principles on high school mathematics instructional design based on constructivist are summarized, in the basis of which, a model of mathematics instructional design with a certain degree of operation based on constructivist is constructed. Further more, the model is used to analysis the following teaching instructional design links:(1) goal analysis;(2) students'characteristics analysis;(3) the characteristics analysis of learning content;(4) situation establishment;(5) independent learning design;(6) instructional appraisal design. Because these kinds of instructional design model emphases students are the master of cognitive process and the active constructor of significance, it is helpful for students to explore and discover initiatively.Applying the model, two specific teaching design cases have been investigated preliminarily, and some conclusions are arrived:(1) constructivist teaching design is more suitable for those lessons concerning important concepts, and laws, and those which can provide rich teaching circumstances;(2) the design of teaching aims should emphasize the integrety and real situation of the lessons;(3) teachers should strengthen the design for students'cognitive foundation and methods;(4) students'self-initiated learning strategy should be made according to the characteristics of both the teaching contents and the learner;(5) some appropriate intense training and exploring training should be provided, which is helpful to realize constructivist of significance;(6) more retrospects and evaluations based on self-awareness should be adopted.
