【摘要】：化学作为一门以实验为基础的自然学科,在中学化学教学中,实验教学在化学教学过程中有着极为重要的地位和作用。新一轮基础教育改革以提高学生的科学素养为主旨,且极力倡导学生的自主学习。对于化学学科,化学实验作为最能体现学生综合素质的落脚点,在化学教学中有着极其重要的作用和地位。化学实验不仅是中学化学的重要教学内容,同时也是落实化学课程改革的重要手段。在高中复习阶段,课时紧张,内容繁多,学生负担重,效率是生命。以往的复习教学中,课堂上教师长篇累牍讲授知识,课后学生进行题海训练,如此的复习模式,教师累,学生也累,学习效率也不高。在复习课上其实学生并不缺乏知识,而是不能够很好的把已经所学的知识进行合理的整合,形成自己的知识结构,从而提高解决化学问题的能力。在化学实验复习课上,教师难以将实验再次实际操作演示,按照传统的复习方法,不能使学生产生感官的冲击,并且学生的学习也是亦步亦趋,缺乏主动性。微课导学教学模式异于传统的化学实验课教学策略,它是在国家极力倡导教育信息化的背景下以及信息技术不断推陈出新的基础上形成的一种教学模式。有关微课研究的整体趋势主要是微课的开发利用与应用研究,而将微课应用于实践教学中才能体现微课与具体学科相结合的真正价值。本文提出的高中化学实验复习课采用微课结合导学案的教学模式,是建立在微课资源开发以及导学案的应用基础上,这种教学模式下,学生课前通过微课和导学案的帮助进行自主学习,把先学过程中暴露或疑惑的问题放在课堂上交流探究,再利用习题的及时跟踪,在原有知识基础上进行强化、延伸,达到更好的复习效率。微课导学的教学模式弥补了化学实验复习课的遗憾,微课视频可以将实验、图像、声音、文字、动画等内容合理的融在一起,导学案的充分利用可以提高学生的学习自主性,并且促进学生进行知识的建构,学生根据自己的学习情况,自由选择地进行自主复习,这样可以达到事半功倍的效果。
[Abstract]:Chemistry, as a natural subject based on experiment, plays an important role in chemistry teaching in middle school. The new round of basic education reform aims at improving students' scientific literacy, and strongly advocates students' independent learning. For the chemistry subject, chemical experiment, as the foothold of students' comprehensive quality, plays an extremely important role and position in chemistry teaching. Chemistry experiment is not only an important teaching content of middle school chemistry, but also an important means to carry out chemistry curriculum reform. In the high school review stage, the class hours are tense, the content is various, the student burden is heavy, the efficiency is the life. In the past review teaching, the teacher in the classroom teaches the knowledge extensively, after class the student carries on the question sea training, such review pattern, the teacher is tired, the student is also tired, the study efficiency is also not high. In fact, the students are not lack of knowledge, but they can not integrate the knowledge they have learned to form their own knowledge structure, so as to improve the ability of solving chemical problems. In the chemistry experiment review class, the teacher is difficult to demonstrate the experiment again, according to the traditional review method, can not cause the students to produce the sensory impact, and the student's study is also follows step by step, lacks the initiative. The teaching mode of micro-lesson guidance is different from the traditional teaching strategy of chemical experiment course. It is a kind of teaching mode which is formed on the basis of the national background of advocating the education information and the information technology constantly bringing forth the old and the new. The whole trend of micro-course research is mainly the development and application of micro-lesson, but the application of micro-lesson in practical teaching can reflect the real value of combining micro-lesson with specific subject. In this paper, the chemistry experiment review course in senior high school is based on the development of microcourse resources and the application of teaching plan. Students learn independently through the help of micro-classes and guided study plans before class. They put the problems exposed or confused in the process of study in the classroom to communicate and explore, and then use the timely tracking of exercises to strengthen and extend the original knowledge. To achieve better review efficiency. The teaching mode of micro-lesson guide makes up for the regret of the chemistry experiment review class. The video of micro-lesson can combine the experiment, image, sound, text, animation and so on reasonably, and the full use of the guide plan can improve the students' learning autonomy. And promote the students to construct knowledge, students according to their own learning situation, the free choice of independent review, so as to achieve twice the result with half the effort.
