二十世纪八十年代生物科学进入分子生物学水平,它在整个自然科学中逐渐起着领先地位,人们预言,二十一世纪将是生物学时代。生物教学改革必须迅速跟上时代的需要。科学实验是认识和研究生物的基本手段之一,实验技能则是完成科学实验的基本保证。中学生物实验教学的基本任务是培养学生独立地进行实验的能力。包括实验技能和观察、分析、综合问题的能力。这是中学生物教学中基本训练的重要内容之一。对于实验知识与技能的考查,按传统做法仅在期末考卷中作书面考查,结果只能反映学生
Biological science entered the molecular biology level in the 1980s. It gradually takes the leading position in the entire natural science. People predict that the 21st century will be a biological era. The biological teaching reform must quickly keep up with the needs of the times. Scientific experiment is one of the basic means of understanding and studying biology, and experimental skills are the basic guarantee for completing scientific experiment. The basic task of high school biology experiment teaching is to train students’ ability to conduct experiments independently. Including experimental skills and the ability to observe, analyze and synthesize problems. This is one of the important contents of basic training in biology teaching in middle school. For the test of experimental knowledge and skills, according to the traditional approach only in the final exam papers for examination, the results can only reflect the students
