强化化学实验教学 加强学生能力培养

实验教学是化学教学的重要组成部分和手段。化学教师应结合实际,充分挖掘化学实验教学的教育教学功能。为了培养学生的观察能力、动手操作能力、创新能力和综合分析能力,文章就如何强化实验教学提出几点建议。     

师范生"化学教学论"实验演说改革的实验

化学是一门以实验为基础的学科,中学化学教学离不开实验教学,为了提高师范生教学能力,我们将原来的只做试验,改为先做试验,再进行边讲边做试验的演说,效果显著.

The role of scaling up research in designing for and evaluating robustness

One of the great strengths of Jim Kaput’s research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, “democratizing access to the mathematics of change,” was enacted by deliberate efforts to reach an increasing number of teachers and students each year. Further, Kaput asked: What can we learn from research at the next level of scale (e.g., beyond a few classrooms at a time) that we cannot learn from other sources? In this article, we develop an argument that scaling up research can contribute important new knowledge by focusing researchers’ attention on the robustness of an innovation when used by varied students, teachers, classrooms, schools, and regions. The concept of robustness requires additional discipline both in the design process and in the conduct of valid research. By examining a progression of three studies in the Scaling Up SimCalc program, we articulate how scaling up research can contribute to designing for and evaluating robustness.     

An integrated and open-ended experiment

In this article we discuss an exciting experiment in non-linear dynamics. This provides an imaginative platform for bringing in chemical, physical, biological, mathematical and computational sciences together. There are implications for earth sciences as well. B M Deb is a theoretical chemist who has been designing experiments for chemistry teaching laboratories for more than thirty years. Mainak Sadhukhan, Sudarson Sekhar Sinha and Sucheta Sengupta were students of PBIR-Chemical Sciences. Ranjit Biswas is a physical chemist working on both theory and experiment in chemical dynamics.     

基于网络的物理实验课程教学管理系统的设计

研究了物理实验全面开放的教学方法,介绍了基于B/S结构的网上物理实验教学管理系统,实现了动态Web开放式、交互式的远程实验教学辅助功能,并详细阐述了设计思想、结构模式、主要功能及系统实现。     

材料类课程配套实验课工程能力培养的探讨

文中对工科学生材料类课程配套实验中加强工程能力的培养进行了探讨。并对传统的实验教学模式进行了分析,提出了在材料类课程的配套实验中加强工程能力培养的基本思路,将实验教学与课堂理论教学相结合、全面推进综合设计性实验和工程技能性实验的改革方案,并对适应于不同专业类别课程的实验教学内容进行了调整和更新。     

实验室测定液体粘滞系数的一种新方法

依据泊肃叶定律给出的描述液体粘滞系数的公式,自行设计实验装置,测量出有关量,计算液体粘滞系数并与理论值进行比较。实验结果能较好地反映粘滞系数与液体温度关系的变化趋势。     

大学工科学生实验的过程评价模式研究

文章分析了当前大学工科学生实验评价系统存在的公平性,交互性、时效性等问题,提出了一种基于过程评价的学生实验评价新模式。该模式强调实验的全过程评价,体现了计算机辅助实验的特色和"以学生为本"的理念。文中同时介绍了该模式在电信和通信专业大三的"通信原理"实验中进行的实践及效果。
