【摘要】：内蒙古地区的旗(县)中学,受限于地理环境、经济文化、教学条件等多方面制约,办学水平处于较低层次。尽管这类学校近年来也在尝试推进某些方面的教学改革,意在提升办学质量,但从笔者所在学校的实践经验来看,以往课改措施的实际成效与预期估计存在较大落差。笔者所在校的初中化学教学实际情况是:限于经费,很多化学实验不能实际进行;受择校的影响,学习能力强的学生流转它校,在读学生基础相对薄弱,主动学习动力不足,自主学习意识淡漠。针对这一状况,本研究着眼于设计、制作一些相关教学内容的微课资源,尝试将微课资源支持下的翻转课堂教学模式运用初三化学教学中,以期提高学生的学习成绩和自主学习能力。籍此探寻提高初中化学课程教学质量的具体策略,旨在为同类学校、同一学段、同类课程的教改开展提供参考与借鉴。本研究主要采用实验法进行,并将文献调研、问卷调查、访谈等多种方法综合运用。研究采用实验组对照组前后测设计。先利用前期有关数据选取起点基本相同的两个班(实验班和对照班),并选择初中化学“构成物质的微粒”单元进行微课教学设计及录制;然后在实验班采用微课资源支持下的翻转课堂教学模式开展教学,对照班仍采用传统常规的以教为主教学模式,实验过程中注意对干扰变量加以控制;实验后测以学校月考试卷为主要依据,从中遴选出与微课学习直接相关的内容,采集习题测试数据进行统计推断分析,检验研究假设;实验研究后期,对学生开展问卷调查和访谈,综合统计推断和问卷访谈结果得出研究结论。初步的分析结果表明,微课资源支持下的翻转课堂教学模式有助于提高初中生的化学学习成绩,利于自主学习能力的培养。本文最后,对整个实验研究过程进行了反思,找出了其中存在的主要不足,明确今后进一步的努力方向。
[Abstract]:The flag (county) middle schools in Inner Mongolia are restricted by geographical environment, economy and culture, teaching conditions and so on, and the level of running a school is at a lower level. Although this kind of school is trying to promote some aspects of teaching reform in recent years in order to improve the quality of running a school, but from the practical experience of my school, there is a big gap between the actual effect of the previous curriculum reform measures and the expected estimate. The actual situation of chemistry teaching in junior high school is: limited to funds, many chemical experiments can not be carried out practically; students with strong learning ability are transferred to other schools under the influence of school selection, and the students' foundation is relatively weak, and the active learning motivation is insufficient. The consciousness of autonomous learning is indifferent. In view of this situation, this research focuses on designing and making some micro-lesson resources of related teaching contents, and tries to apply the flipping classroom teaching model supported by micro-lesson resources to junior high school chemistry teaching. In order to improve students' academic performance and autonomous learning ability. The purpose of this paper is to provide reference and reference for the development of the teaching reform of the same school, the same learning section and the same curriculum in order to explore the specific strategies to improve the teaching quality of the chemistry course in junior high school. This research mainly adopts the experimental method, and the literature investigation, the questionnaire survey, the interview and so on many kinds of methods synthetically uses. The experimental group was designed before and after the test. First, two classes with the same starting point (the experimental class and the control class) were selected by using the related data in the early stage, and the micro-course teaching design and recording were carried out by selecting the "particle of the constituent matter" unit of junior high school chemistry. Then the experimental class adopts the flipping classroom teaching mode supported by the micro-lesson resources, while the control class still adopts the traditional teaching-oriented teaching mode, and pays attention to the control of the disturbance variables in the process of experiment. After the experiment, the main basis of the test paper is the school monthly test paper, from which the contents directly related to the micro-lesson learning are selected, and the data of the exercise test are collected for statistical inference and analysis, and the research hypotheses are tested; at the later stage of the experimental study, Questionnaires and interviews were conducted to the students, and comprehensive statistical inference and questionnaire interviews were conducted to draw the conclusion of the research. The results show that the flipped classroom teaching model with the support of micro-course resources is helpful to improve junior high school students' chemistry learning achievement and to cultivate their autonomous learning ability. At the end of this paper, the author reflects on the whole process of experimental research, finds out the main shortcomings, and makes clear the direction of further efforts in the future.
