计算机教育是一项面向未来的现代化教育,许多中小学校都已装备了机房,但把计算机应用于课堂教学的还很少。要打破一些传统的、陈旧的教学方法,就要充分发挥多媒体的优势,优化课堂教学。本人在执教生物过程中,已在这方面进行了探索,并取得了较好的效果。现以“肺的通气”一课谈几点看法: 1 制作图片本堂课制作的图像有“呼吸系统的模式图”、“肺的内部结构示意图”。图片的制作可以先用扫描仪把书上的图像扫进去,然后再在PHOTOSHOP软件中进行编辑,可把不同的部位着上不同的颜色,还可把重要部位进行放大,这样就提高了学生对肺的感性认识。 2 制作动画
Computer education is a future-oriented modern education. Many primary and secondary schools are equipped with computer labs, but few computers are used in classroom teaching. To break some traditional, outdated teaching methods, it is necessary to give full play to the advantages of multimedia to optimize classroom teaching. In my coaching biology, I have explored it in this area and achieved good results. Now to “lung ventilation ” a lesson a few observations: 1 make a picture of the class images produced “respiratory system pattern ”, “internal structure of the lung ”. The picture can be made by scanning the book with a scanner and then editing it in the PHOTOSHOP software, putting different parts in different colors and magnifying important parts, thus improving the students' Perception of the lungs. 2 animation
