【摘要】：新一轮的基础教育改革在全国各地铺展开来,核心理念是:为了中华民族的复兴,为了每一位学生的发展。这就决定了我国基础教育课程体系要进行转变。如何让每一位学生都得以发展,从古至今,是国内外每一位教育工作者共同关注的话题。在信息科学技术飞速发展的今天,各种移动终端设备出现在我们的生活中,课程与现代信息技术相结合,使因材施教成为了可能,微课用于分层教学恰好能满足这种需求。在化学学科分层教学中运用微课,为每个层次的同学都提供了适合的学习平台,提高教学效率,分层作业、分层考核更有利于提升学生学习兴趣和学习成绩。论文综述了微课和分层教学的国内研究现状,解析了微课与分层教学的概念和特点,提出了微课应用于分层教学的教学策略,整个环节从学生的学情出发,以微视频为核心,微课件融入教师教学设计,微练习与学生任务相联系,微反思融入评价之中。重点是设计了微课在高中化学分层教学中应用的教学案例,并且在高一化学教学中进行教学实践研究。根据月考成绩选取两个无明显差异的班级进行对照实验。实验班采用微课结合分层教学的教学方式进行教学,以考试成绩为重要的参照标准对学生进行分层,学习目标、练习题、课堂提问、作业、评价等各个教学环节都分层设置,并设计微课进行教学实践,实验后,实验班成绩明显优于对照班。微课用于分层教学,能够培养学生自学能力,提高课堂教学效果。课前自主学习让课堂学习变得更容易、更轻松,还能提高学生能动性,使学生的学习成绩、学习兴趣、学习积极性都有提高,微课与分层相结合的教学模式在高中化学教学中是一种切实可行的教学模式。
[Abstract]:A new round of basic education reform spread throughout the country, the core idea is: for the rejuvenation of the Chinese nation, for the development of every student.This decided our country elementary education curriculum system to carry on the transformation.How to make every student develop is a common concern of every educator at home and abroad.With the rapid development of information science and technology, all kinds of mobile terminal devices appear in our life. The combination of curriculum and modern information technology makes it possible to teach students in accordance with their aptitude.The application of microcourses in the stratified teaching of chemistry courses provides a suitable learning platform for students at each level, and improves teaching efficiency, stratification of homework, and assessment of stratification, which is more conducive to enhancing students' interest in learning and academic achievement.This paper summarizes the domestic research status of micro-lesson and layered teaching, analyzes the concept and characteristics of micro-lesson and layered teaching, and puts forward the teaching strategy of applying micro-lesson to layered teaching. The whole link starts from the students' learning situation and takes micro-video as the core.The micro courseware is integrated into the teacher's teaching design, the micro exercise is related with the students' tasks, and the micro reflection is integrated into the evaluation.The key point is to design the teaching case of the application of microcourse in chemistry stratification teaching in senior high school, and carry on the teaching practice research in the chemistry teaching of senior high school.According to the results of the monthly test, two classes with no significant difference were selected for the control experiment.The experimental class adopts the teaching method of microcourse combined with stratified teaching. Taking the test results as an important reference standard, the students are stratified, learning objectives, exercises, classroom questions, assignments, evaluation and other teaching links are set up at different levels.After the experiment, the result of the experimental class is better than that of the control class.Micro-class is used in stratified teaching, which can cultivate students' self-study ability and improve classroom teaching effect.Self-regulated learning before class makes classroom learning easier and easier. It can also improve students' initiative and improve their academic performance, interest and enthusiasm.The combination of micro-class and stratification is a feasible teaching mode in chemistry teaching in senior high school.
