在科学课堂中运用多媒体进行辅助教学能解决传统实验教学中的一些疑难问题。例如,巧借投影光源建模、摄像头成像促使实验现象直观化;巧借白板,促使分类学习快捷化;巧借计算机,适时呈现幻灯片、音频、视频,并有效利用网络资源,促使教学方式多样化;巧借手机、传感器、显微镜+i Pad等移动电子设备,促使课堂高效化。多媒体的使用无疑为科学教学插上了现代化的翅膀,不仅能丰富课堂,而且能促进学生学习能力、教师信息化水平的提高。
Using multimedia to assist teaching in scientific classroom can solve some difficult problems in traditional experimental teaching. For example, using a projection light source as a model, camera imaging facilitates the visualization of experimental phenomena; skillfully borrowing a whiteboard to facilitate classification learning; skillfully borrowing a computer to present slides, audio and video in good time and make effective use of online resources to promote a variety of teaching methods By using mobile devices such as cell phones, sensors, microscopes and i Pads, we can make the classroom more efficient. The use of multimedia undoubtedly plugged in modern science teaching wings, not only enrich the classroom, but also to promote student learning ability, teachers improve the level of information technology.
