Multi-dimensional interactive teaching mode focuses on the teacher-student and student-student interactions. It implements the education conception of student as the subject and teacher as the guider. It is an effective way to cultivate high quality individuals with innovative and practical abilities. This paper sets forth the necessity and measures to carry out the multi-dimensional interactive teaching mode in the laboratory teaching of preparation of ferrous ammonium sulfate. The measures include defining the teaching aim, asking interactive questions, experiencing interactive activities and conducting interactive evaluation. Those measures make it possible to achieve the goals of promoting the students' comprehensive development of knowledge, ability, emotion, attitude as well as personal integrity. 相似文献

长期以来,稀溶液中溶剂A的化学势为μA(1)=μ^*A(1)+RTlnxA,溶质B的化学势为μB(溶质)=μ^ΞB(溶质)+RTln(bB/b^Ξ),两式使用了不同的组成变量:溶剂的摩尔分数xA,溶质的质量摩尔浓度bB。按规定,溶液的组成变量应选用bB,故本文介绍了导出理想稀溶液中μA(1)=μ^*A(1)-RTMA∑BbB的方法,并从此式出发推导出稀溶液的依数性。 相似文献

This paper introduces the implement program and significance of the teaching reform of student-centered teaching mode, on the basis of classroom practice in general chemistry laboratory. A complete comparisons between the student-centered teaching mode and teacher-centered teaching mode were carried out in many aspects, such as teaching process, teaching evaluation, teaching implementation effect, etc. The main status of students should be built and all efforts are made focusing the students in student-centered teaching mode. Students can absorb knowledge, improve ability, and cultivate healthy personality by online and offline teaching models, heuristic teaching methods and cooperative learning strategies, which were implemented with the Superstar learning platform. The student-centered teaching mode helps to build a harmonious relationship between teachers and students, cultivate students' scientific literacy and humanistic quality, and promote the all-round development of students. 相似文献

利用△G=△H-T△S推导了稀溶液凝固点降低公式,根据形成溶液前后相变熵的改变,对公式的含义进行了解读,即凝固点的降低完全归结于溶解过程相比于熔化过程的熵变增加.并对公式的拓展应用进行了简要分析. 相似文献

探索了一种以微信公众平台为载体、以案例为启发点、问题为导向,将线上自学、线下讲解和实验训练相结合的多维教学模式,用于无机及分析化学实验教学中。通过期末考试、教学质量评价和问卷调查的方式,从学生学习效果、学习兴趣、能力培养等方面对4个教改班和平行班进行了对比。结果表明,教改班的教学效果明显优于平行班,4个教改班的考试平均分比平行班的平均分高12.6分。新的多维教学模式不仅解决了学生实验效果差、实验室周转紧张等问题,还能充分调动学生学习兴趣、激发实验热情、提升科研素养,为培养创新型人才奠定基础。 相似文献
