随着计算机多媒体技术，尤其是网络技术的迅速发展，现代教育技术由电化教学、计算机辅助教学向网络环境下的教学过渡。人们对于信息技术中的多媒体与网络技术的特点及其应用于教学的优势已经有了比较全面的认识。并且在各种教育教学理论的指导下，对以网络技术为核心的信息技术应用于教学的教学模式、教与学的策略、基于信息资源的教学等进行了深入的研究，取得了开创性的成果。但就目前来看，在网络环境下进行化学学科的教学设计研究还比较少，尤其是在网络环境下进行高中化学实验探究教学的研究非常罕见。化学是以实验为基础的学科，引导学生进行实验探究是学好化学非常重要的一部分。然而仅仅利用常规实验教学很难满足学生进行实验探究的需要，因为探究过程需要大量的资源，以及真实的探究环境。但是网络技术的引入恰恰解决了这些问题，使得学生进行实验探究成为可能。本论文以前人已经开发出的网络环境下的教学模式为基础，结合高中化学实验探究教学实际情况，通过查阅文献、问卷调研及理论分析，论证了将二者结合的必要性和可行性。然后又选择了几个实验活动主题进行尝试，首先根据各实验活动内容特征，选择合适的教学模式进行设计，并分阶段对学生的实验探究能力进行培养。实验结束后，以调查问卷的形式对实验的效果进行了分析，并对实验班和对照班进行了一次实验探究专项测试。结果表明，实验班明显好于对照班。从而有力地证实：在网络环境下进行实验探究教学是非常有效的。最后，讨论了在网络环境下进行实验探究教学过程中存在的问题，以及如何进一步去完善。

With the development of the multimedia technology of computers, especially the development of network technology, the modern education technology has changed from the audiovisual teaching, and the teaching aided by computers to the teaching under the network environment. Now, people have had a good knowledge of the characteristics of the multimedia and network technology of the information technology. They also understand the advantages when they are applied to teaching. With the instructions of different kinds of education teaching theory, people have further researched into the teaching model, strategy and the teaching based on information resources, which are all about the application of information technology, taking the network as the core. They have achieved a groundbreaking result.At present, few people do the research into the teaching design of chemistry under the network environment; especially, it is extremely rare to do the research into the high school chemistry exploration under the network environment. Chemistry is a subject based on experiments, and it is extremely important part to guide the students to carry on the experiment exploration to learn chemistry well. However, it is merely difficult to satisfy the students’ needs to carry on the experiment exploration by using the conventional experiment teaching because they need the massive resources as well as real exploratory environment, during the process of exploration. The introduction of the network has solved these problems exactly and it makes it more convenient for students to carry on the experiment exploration.This article has proven the necessity and feasibility to combine the actual situation of high school chemistry experiment exploration with the teaching model. Under network environment which has been developed, through consulting literature, the questionnaire investigation and the theoretical analysis. Then, choose several experiment subjects to try. First, choose the appropriate educational model to carry on the design according to the characteristics of each experiment contents. After the experiment ends, carry on the analysis to the effect of the experiment by the way of questionnaire and have a chemistry test. The result indicates that the students of tested class are better than the other one. This powerfully confirms that it is effective to carry on the teaching of experiment exploration under the network environment.Finally, discuss the problems that exist the process of the teaching of experiment exploration and how to improve them.
