实验教学在各个阶段的教育中都占据着非常重要的地位。前实验作为学生开展实验过程的先验知识,是实验教学的重要组成部分。本文系统地分析了近20年来国内外化学前实验教学研究的现状;首先通过中国知网检索分析了国内化学前实验教学研究的进展,并总结了其不足之处;之后通过web of science检索分析了国外化学前实验教学研究方面的进展,可将化学前实验教学研究分为创新前实验方式研究类、前实验方式比较类、前实验对学生认知变化研究类和完整实验研究类等4大类,并分别展开详细分析和讨论;最后从研究对象、研究内容、研究方法等方面总结了化学前实验教学研究的启示与建议。 相似文献

以“乙酸乙烯酯的乳液聚合”理论课和实验课为例,探索了将高分子化学理论和实验课程进行融合的创新教学模式。将理论教学和实验教学进行互动和融合的整体安排,克服了传统教学中理论课和实验课相互分离、缺乏相互支撑的缺点。在融合教学模式中,理论课和实验课实行团队协同教学;在同一个实验中设置必修内容和扩展性内容,更好地培养学有余力的学生;将理论课和实验课进行综合考核;对比了实验课前置、实验课居中和实验课后置教学方式,其中实验课居中的融合教学适合于大部分学生,有助于提高学生学习质量。 相似文献

In the era of "Internet +", with the help of national excellent MOOC course of Chinese university and Mlabs-virtual experimental software, Tencent classroom is built to provide a diversified and efficient online inorganic chemistry basic laboratory classroom by combining a variety of modern education technologies with the concept of flipped classroom. Taking the redox reaction experiment as an example, we designed a multi-link teaching process and carried out a multi-faceted assessment. The online teaching can not only strengthen the cultivation of students' comprehensive and innovating ability, but also help teachers to update the teaching mode and create the new experimental content in line with the development of the times, so as to realize the mutual learning between teachers and students in the exploration of experimental teaching reform. 相似文献

Experimental chemistry is an important public foundation course for the undergraduate student during their first year at Shihezi University. This paper introduces the teaching status and implementation of the experimental chemistry curriculum. Based on the student activities, this paper firstly constructs flipped learning mode of the experimental chemistry, combining the curriculum resource preparation with online and offline teaching. Secondly, the experimental chemistry curriculum takes deep integration of information technology and classroom teaching as an opportunity. Furthermore, the teaching implementation is carried out by the network teaching platform of Shihezi university. Finally, the student's questionnaire displays that it works well in improving the teaching quality. 相似文献

The current situation of analytical chemistry teaching and reform, as well as some problems in micro-videos of online classroom was analyzed. In order to solve these problems, short experimental videos were introduced to the online classroom to demonstrate experimental methods. The new teaching mode achieves mutual integration and promotion of the classroom teaching and laboratory teaching, providing opportunities and challenges for the teaching reform of chemistry online course. The results of the teaching reform were investigated and analyzed by questionnaire. 相似文献
