学习立体几何,重在培养学生对空间图形的认知能力、动手操作能力、合情推理能力、空间想象能力和逻辑推理能力。中职学生对立体几何学习缺乏兴趣,无法识图、推理、计算。而多媒体技术在立体几何教学中有很大的作用,可大大降低学习的难度,增强趣味性、直观性,起到仿真效果;能为几何教学创设情境,激发学生兴趣;揭示事物本质、形成数学概念;促进学生自主探索,拓宽学生思维;增加课堂容量,提高教学实效。借多媒体技术之帆,给数学课堂教学之船增添一股动力,在数学大海中扬帆远航。
Learn three-dimensional geometry, focusing on developing students’ cognitive ability to space graphics, hands-on ability, emotional reasoning ability, spatial imagination and logical reasoning ability. Secondary vocational students lack of interest in the study of three-dimensional geometry, can not figure, reasoning, calculation. The multimedia technology in the teaching of three-dimensional geometry has a great role, can greatly reduce the difficulty of learning and enhance the fun, intuitive, simulation effect; geometry teaching can create situations to stimulate student interest; Reveal the nature of things, the formation of mathematics Concept; to promote independent exploration of students, broaden students’ thinking; increase classroom capacity, improve teaching effectiveness. By the multimedia technology of the sail, to mathematics class teaching ship to add an impetus to sail in the math sea voyage.
