【摘要】：随着互联网的时代到来,人手一部移动终端已是常态,观看微课来进行学习的这种方式越来越受到大家的欢迎。初三化学的教学时间紧,教学任务重,特别是化学概念繁多、抽象难以理解,为了更高效的教学,突破化学教学内容上的一些难点,利用微课短小精悍的特点,使之与其它教学手段有机结合优化课堂教学,更能让学习者直接领会到学习目标,提高学习效率。本研究在以利用微课突破初中化疑难知识的学习方式为出发点,采用文献法对该主题的研究现状进行文献综述,在建构主义理论、混合学习理论、自主学习等理论基础上,结合本地区的实际情况设计了相关的调查问卷进行调查分析,对本研究进行可行性分析和确定了初中化学知识的疑难点,继而针对疑难点制作开发相关的微课和进行教学设计,在实际教学中运用微课在初中化学疑难知识的课前、课中、课后三种模式进行了教学实践,最后采用问卷调查法、访谈法、期末考试成绩对比对教学实践效果进行了总结和反思。通过实践得到微课是一种解决初中化学疑难知识的教学有效方式。经过一年的教学实践,证实了“微课运用于初中化学教学疑难知识”在初中化学教学具有一定的可实施性,并为后续进行该研究的研究者提供了实际经验支持,同时本研究还生成了大量的网络初中化学优质课程资源。在今后的教学中,继续运用到实际教学中,并不断的改进和完善。
[Abstract]:With the advent of the Internet era, a mobile terminal has been the norm, watching micro-classes to learn this way is more and more popular. The teaching time of junior high school chemistry is tight, teaching task is heavy. In particular, the concept of chemistry is various, abstract is difficult to understand, in order to more efficient teaching, break through some difficult points in the content of chemistry teaching, the use of micro-courses short and tough characteristics. So that it can be combined with other teaching means to optimize classroom teaching, so that learners can directly understand the learning goals. To improve the efficiency of learning. This study is based on the use of micro-curriculum to break through the difficult knowledge of junior high school learning as a starting point, the use of literature on the subject of the current situation of literature review, in the constructivism theory. On the basis of mixed learning theory, autonomous learning theory and so on, the questionnaire is designed and analyzed according to the actual situation of the region. The feasibility of this study and determine the difficult points of junior high school chemistry knowledge, and then for the difficulties of the development of micro-courses and teaching design. In the actual teaching, the use of micro-class in junior high school chemistry difficult knowledge before, in class, after the three modes of teaching practice, the final use of questionnaires, interviews. The comparison of final examination results summarizes and reflects on the effect of teaching practice. It is an effective way to solve the difficult knowledge of chemistry in junior high school through the practice of micro-class. After one year of teaching practice. It is proved that the application of microcourse to the difficult knowledge of chemistry teaching in junior high school has certain implementability, and it provides practical experience support for the researchers who carry out this research in the future. At the same time, this research has also generated a large number of network junior high school chemistry high quality curriculum resources, in the future teaching, continue to apply to the actual teaching, and continue to improve and improve.
