目前有关化学实验的教学软件以演示型的居多,交互能力差,表现在学生使用CAI课件学习是被动的。如演示型的课件主要分为自动演播和手动演播,自动演播的课件学习者主要是观看演示正确的操作步骤与实验结果,手动演播增加了按钮控制课件的播放流程,这实际上是没有发挥学生的主动性。定性实验的过程如果通过播放的方式进行再现,学生会觉得乏味和枯燥,很难满足学习者的要求,其原因主要是交互性差,这就要求图文并茂、情景交融、操作方便、具有交互功能的多媒体教学软件。还可根据学习者的操作及时作出正确的反馈,实现真正的人机对话。中学阶段大部分化学实验都是定性实验,这些实验 At present, most of the teaching softwares for chemistry experiments are mostly demo-based with poor interactive ability, which is demonstrated by students’ passive learning of CAI courseware. Such as demonstration courseware is divided into automatic and manual studio, automatic studio courseware learners to watch the demonstration of the correct operation steps and experimental results, manual studio adds button control courseware playback process, which is actually not playing a student Initiative. If the process of qualitative experiment is reproduced by means of playing, the students will feel boring and boring and it is difficult to meet the requirements of the learners. The reason for this is mainly the poor interoperability, which requires multimedia teaching with interactive illustrations and illustrations, blending scenarios, convenient operation and interactive functions software. According to the learner’s operation can also be timely and correct feedback to achieve a real man-machine dialogue. Most chemistry experiments at the secondary level are qualitative experiments, these experiments
