在学习生物时,怎样实现对生物实验的有效学习是众多生物教师亟待解决的一个重要问题。在笔者看来,从生物教学的初始阶段就对生物实验教学进行深入研究发挥着至关重要的作用。一、常规教学中重视实验教学,注意培养和提高学生的能力(一)在常规生物验教学中帮助学生搞清仪器的原理唯有知其然才能知其所以然。为实现高效的实验教学,必须付出较多的努力,使学生对仪器的原理有更深入的了解。比如,在众多生物实验中最为常见且使用最多的显微镜,能否掌
When studying biology, how to realize the effective study of biology experiment is an important problem to be solved urgently by many biology teachers. In my opinion, from the initial stage of biological teaching on biological experiment teaching conducted in-depth study plays a vital role. First, the conventional teaching emphasis on experimental teaching, attention to cultivate and improve the ability of students (a) in conventional biological teaching to help students find out the principle of the instrument only know it before they know why. In order to realize efficient experimental teaching, more efforts must be made to enable students to have a deeper understanding of the principle of the instrument. For example, in many biological experiments the most common and most used microscope, can palm
