Analysis Based On Quality Improvement Of Junior School Geometry Classroom

Geometry teaching content in continuous improvement and change, new ideas, requirements constantly enrich our geometry teaching requirements, will require our teaching methods will also be practical and improvement.The author by nearly 2 years of study paper quality analysis, summarized the students in plane geometry section of typical issues 7, combined with the student and teacher interviews, analyzed the causes. Problems for students, teachers in the "language of training students in geometry, " "experimental operation of the undertaking," "basic graphics library for" context, improved geometry class. Focus on refining middle school eighth-grade "geometry basic graphics", lead the students to understand the changes in the graphics, graphics, shapes, to resolve a graphic. Take the "triangle" and "quadrangle" knowledge points as the carrier, use the "geometry basic graphics" regulation "known" to the "conclusion" of the process. Guide students to establish the concept of geometric patterns, forming a basic graph pattern library, the students improve their geometric reasoning ability.Through teacher in the language, the experimental operation, basic graphical method of practice teaching, for students of the geometry to be logging capability, results show:teachers to geometric language (especially graphics language) transformations, emphasizing geometry basic graphics rendering and decomposing portfolio, training students to use geometric basic graphics to understand and remember geometry theorem and the nature of the improvement of teaching methods, results, accuracy and robustness of memory have been greatly improved. At the same time, the geometry of the Visual memory effectively contribute to the formation of the migration capabilities, help to open the thinking in solving problems, find the clues, solve problems faster by allowing greater improvement. But in solving problems of precise extent is marked improvement, students skip steps, circles, extra proof, or more. In General, teachers in geometry class improvements achieved preliminary results. Therefore in junior high school geometry course focuses on the following two improvements, to enhance students'strict geometric reasoning demonstrating capabilities:(1) strengthening the training of geometric language;(2) to pay attention to the refinement of geometric basic graphics.
