Based On The Geometric Sketchpad Secondary Solid Geometry Inquiry-based Teaching Model And Case Study

Mathematics is well known training logical thinking, especially solid geometry, educational software from abroad, "Sketchpad" learning portal for its easy and simple operation and the advantages of a powerful graphics and video capabilities to facilitate the animation functions are many domestic Mathematics teachers optimistic, and has become one of the main production level mathematics courseware authoring platform. Strengthen the study of the effectiveness of vocational school students solid geometry classroom teaching, in favor of the relevant departments of vocational school students teaching the correct guidance of solid geometry, and can open up a specification and reasonable way of learning Maths Teaching. Papers based on the Geometer's Sketchpad to explore vocational Solid Geometry Exploring Teaching Mode and case, proposed to increase the effectiveness of classroom teaching in vocational solid geometry corresponding strategy to arouse the attention of the academic vocational school mathematics education.Firstly, in theory, based on the Geometer's Sketchpad to explore applications in solid geometry teaching. Thesis by reading literature and data search, clear Sketchpad emergence and development, functions and features as well as the role of understanding Sketchpad use in vocational solid geometry inquiry teaching in order to reflect the Geometer's Sketchpad inquiry teaching in vocational solid geometry Applying importance. Sketchpad applications in solid geometry teaching embodied in the concept of teaching difficulty breakthrough, breakthrough difficulty Theorem teaching difficulty breakthrough in three aspects of teaching problem solving and so on.Secondly, the paper analyzes the level of three-dimensional geometry based on the Geometer's Sketchpad inquiry teaching cases. Firstly, with conic painting as a teaching cases. Conic painting using the properties of the conic conic constructed image, the main advantage of a variety of track processing features "Sketchpad" in the calculations, and the newly developed, very easy to produce a more ideal demonstration courseware. Next to the paper rotating body coplanar straight for teaching Lesson two, the case is mainly related graphics are constructed in accordance with the first courseware production techniques, use of relevant features of the Geometer's Sketchpad, flashes and other functions to achieve through skills, combined with teaching students the ability to multi-faceted. Finally, the case implementation and effect analysis showed that after a period of inquiry teaching students to recognize research program for the three-dimensional geometry of interest in learning experiment, explore awareness of the problem has been greatly improved.Finally, the paper proposes a perspective based on the Geometer's Sketchpad in vocational geometric inquiry teaching mode. First, the paper defined the basic principles to instructional design, including the principle of subjectivity, layer by layer abstract principles and the principle of seeking truth from facts. Secondly, the paper proposed based on the Geometer's Sketchpad in vocational Solid Geometry inquiry teaching mode, is a problem the main line, teaching materials based on the platform as a tool for the student, teacher-centered teaching model, including the first class teaching mode, teaching mode curricular and after-school teaching. Finally, the paper proposes a perspective based on the Geometer's Sketchpad in vocational geometric inquiry teaching application strategy, including a strategy to stimulate and constructing tactics.Sketchpad teaching with case papers, find out the advantages of teaching Geometer's Sketchpad, and propose future. Research students from learning disabilities, mental disorders start doing preliminary exploration of teaching and research in mathematics. Secondly, a number of levels to strengthen the proposed use Geometer's Sketchpad in vocational teaching solid geometry inquiry specific measures. Such a special group of three-dimensional geometric inquiry teaching model for students in vocational studies, on the one hand based on the author teaching practice, hoping to provide a more realistic approach to the future of classroom teaching.
