【摘要】：虚拟实验依托计算机、多媒体、虚拟仿真等技术,营造出高度仿真的实验环境和实验对象,在计算机上完成实验操作全过程。借助互联网,它可以打破时空限制,弥补实验教学的不足,满足新课标的要求。但缺乏科学的运行模式,导致其在当前教学中未能发挥应有的教学优势。因此,构建高效的虚拟实验教学模式成为教育者研究的热点。首先,以构建科学高效的网络虚拟实验教学模式为主线,列举基于“互联网+”的化学实验虚拟教学原则,提出依托互联网的化学虚拟实验教学模式设计思路。接着,对广东地区高中生关于虚拟实验教学的认可度、适应性,教师的信息技术水平和信息化教学观念,学校及家庭的计算机等硬件设施配套和网络覆盖情况等问题进行问卷调查,得出本研究的可行性。然后,依托互联网,构建“二三四”化学虚拟实验教学模式,设计了虚拟实验平台以支撑本教学模式的实施。该模式的亮点在于贯穿课前至课后,集实验探究、合作交流、问题解答、练习评价为一体。分别选择气体制备实验、探究性实验和微观化学实验的典例进行设计和分析。最后,运用对比实验教学法对实习学校两个班级试行,得出本教学模式提高了实验教学质量,又有利于培养学生的自主探究精神和创新实践能力,符合新课标的要求。
[Abstract]:Based on computer, multimedia and virtual simulation technology, virtual experiment creates a highly simulated experimental environment and experimental object, and completes the whole process of experiment operation on the computer. With the help of the Internet, it can break the limitation of time and space, make up for the deficiency of experimental teaching and meet the requirements of the new curriculum standard. However, the lack of scientific operation mode leads to its failure to give full play to its teaching advantages in current teaching. Therefore, the construction of an efficient virtual experimental teaching model has become a hot topic for educators. Firstly, taking the construction of a scientific and efficient virtual experiment teaching model as the main line, this paper enumerates the virtual teaching principles of chemical experiment based on the Internet, and puts forward the design idea of the virtual experiment teaching mode based on the Internet. Then, the recognition, adaptability, information technology level of teachers and the concept of informational teaching for high school students in Guangdong area about virtual experiment teaching are discussed. The feasibility of this study was obtained by questionnaire survey on hardware facilities and network coverage of schools and families. Then, based on the Internet, the "two three four" chemistry virtual experiment teaching model is constructed, and the virtual experiment platform is designed to support the implementation of this teaching model. The highlight of this model is that it combines experimental inquiry, cooperative communication, problem solving and practice evaluation. Examples of gas preparation experiment, inquiry experiment and microchemistry experiment were selected for design and analysis. Finally, using the comparative experimental teaching method to try out the two classes in the practice school, it is concluded that this teaching mode not only improves the quality of the experimental teaching, but also helps to cultivate the students' spirit of independent inquiry and innovative practical ability, and meets the requirements of the new curriculum standard.
