为积极响应新课改.我校于2004年秋季采用了普通高中课程标准实验教科书(人教版)。“检测生物组织中的糖类、脂肪和蛋白质”是其必修部分“分子与细胞”模块的第二个学生实验。在多年的实验教学实践中,我校生物组教师对该实验进行了反复研究,化繁为简并探讨出了更经济实用、实验效果更理想的科学实验方法。现做如下小结,供同仁参考。一、对实验材料的探讨教材对实验材料只提供了名称,并没有质量浓度,当
In order to respond positively to the new curriculum reform, our school adopted the ordinary high school curriculum standard experimental textbook (PEP) in autumn 2004. The second student experiment “Detecting carbohydrates, fats and proteins in biological tissues” is a compulsory part of its “Molecular and Cellular” module. In many years of experimental teaching practice, our school biology group teachers conducted repeated research on the experiment, simplifying and simplifying to explore a more economical and practical, experimental experimental results better scientific experimental methods. Now do the following summary for my colleagues in reference. First, the discussion of experimental materials Teaching materials on the experimental materials only provide the name, and no mass concentration, when
