在线课堂作为一种远程教育方式,往往会导致学生缺乏学习社区感。面对抽象的理论性知识,学生易陷入一种“离身”的困境。基于此,借助虚拟化学实验室,设计一堂“身临其境”“做中学”的价层电子对互斥模型课,实现“抽象内容具身认知化”“在线学习互动现实化”的在线课堂深度学习。 相似文献

从知识考古学的视角,分析当前“课堂中的化学平衡”的历史根源。作为简化的学科知识,“教材中的化学平衡”不仅划定了知识的边界,而且内隐了知识的结构;作为演进的理解表现,“高考中的化学平衡”逐步形成了稳定的考查角度和方式。作为实然的教学内容,“课堂中的化学平衡”是多元主体社会协商形成的“共识”,具有区域性特征,包含特定的话语,是一种高度依赖于学校情境的工具化、条件化了的知识。 相似文献

采用“中学化学课堂环境问卷”作为研究工具,对深圳市、长春市、佳木斯市等3个地区的4所高中861名学生的化学课堂环境进行调查,并进行差异分析。研究结果表明,高中生对化学课堂环境的总体感知较好,7个维度中“学生凝聚力”“平等”“任务取向”“合作”等4个维度的平均分大于3.4,“教师支持”和“参与”维度的平均分在3.0~3.4,只有“探究”维度的平均分小于3.0。城市高中生对课堂环境的感知明显好于乡镇高中生,学生心目中所期待的化学课堂比实际的化学课堂更积极。 相似文献

In the on-going tidal waves of MOOCs, the sociality of learning behavior of students has been diluted, which has resulted in unsatisfying effects on both learning and teaching. In this paper, one powerful teaching tool Course Cubic is elucidated in detail. By merging the virtual classroom generated in Course Cubic with physical classroom, the sociality of learning behavior of students was greatly enhanced and the satisfying teaching-and-learning has been achieved. 相似文献

During the years of 2015 to 2018, the inorganic chemistry course in Tianjin University has gradually transited from small private on-line course (SPOC) to flipped classroom. Flipped classroom teaching practices were carried out at more than 30 classes at our university by the sufficient use of on-line course resources. These practices effectively improve the quality of teaching, and greatly solve the problem of poor learning initiative and low participation of the students existing in current traditional teaching model. This article in detail introduces and summarizes the following four aspects, including transition of teaching modes, construction of online resources, online and offline supervising, test scores analysis and teaching thought. The effective ways for flipped classroom mode are discussed to improve students' knowledge and learning ability. And it also provides references for teachers to carry out their classroom teaching reform. 相似文献

Combining the teaching and learning actuality of organic chemistry experiment in Yuxi Normal University, the blended teaching reform based on rain classroom was introduced in this paper. The influence of mixed teaching mode on teaching and learning was discussed from the changes of teacher's teaching, student's learning and evaluation mode. The flip of traditional classroom and the change of roles of teachers and students was realized by the Online and offline teaching mode. The extraction of caffeine from tea was applied to expound the specific application of hybrid teaching in experimental teaching. The practice proved that mixed teaching helped students to improve self-learning ability, innovation and entrepreneurship and comprehensive applied ability. 相似文献
