项目摘要

The molecular model pictures taken by means of a digital camera were projected two times for the first grade students of the chemical course in the 3 hours' fundamental chemical experiments in the period between 1998 to 2001.In those projection, how to recognize the different atoms and the molecular structure differences in the bond length and the bond angle were lectured. And the molecular model pictures rotating, translating and scaling on the computar monitor were projected in abig screen (100 inches size). In orecler to draw the structure of molecular models, a colred atom template (a scale made by paper) was used. The dividing the 40 members in a class into the two 20 members' groups decreased the dispersion in the constructing rate and the drawing rate of the molecular models. The number 20 in a class would be the better than 40.The projection of the structures of the biomolecufe did not affect on the Stereochemical education in the biological chemistry class of the third grade students.In the experimental class of the fifth grade students, constructing the models of the biomolecules ty hands and drawing those on the computar monitor were carried out.The combination of the two different types of molecular models resulted in the good Stereochemical understanding of the students.I believe that agood educational system for the stereochemistry has been established in the 4 years' project.

在1998 ~ 2001年的3学时基础化学实验中，对化学一年级学生用数码相机拍摄的分子模型照片进行了两次投影，并讲授了如何识别不同原子和分子结构在键长和键角上的差异。并将分子模型在计算机显示器上的旋转、平移和缩放图像投影到100英寸大屏幕上。在orecler中绘制分子模型的结构时，使用了彩色原子模板（用纸制成的标尺）。将一个类中的40个成员分成两个20个成员的组，降低了分子模型构建率和绘制率的离散度。在三年级的生物化学实验班中，生物分子结构的投影对立体化学教学没有影响，在五年级的实验班中，生物分子结构的投影对立体化学教学没有影响。建立了生物分子手的模型，并在计算机显示器上进行了绘制，实现了两种不同类型分子手的组合，立体化学教学模式的建立，使学生对立体化学有了较好的理解，相信在四年的教学实践中，立体化学的教学体系已经建立起来。
