(一)问题的提出生物是一门以实验为基础的科学。在中学生物教学中,培养学生学习生物学的兴趣及动手能力,加强实验教学是十分必要的。如何在不加重学生负担,不增加实验设备条件下,采取措施,增加学生自己动手做实验的机会? 我们给学生布置了适量实验作业,让学生在课外利用家里的盆、碗做实验,使第一课堂与第二课堂结合,以激发学生的求知欲,发展思维,培养他们的动手能力。为此,我们随机选择了初二(3)班进行对比试验。 (二)试验的过程及方法试验编组期中考试刚结束,生物教研组在初二年级随机选择了初二(3)班作被试验对象。该班在年级中,学习成绩处中等水平,学风正常。试验前将该班依座次顺序各取一半人编
(A) the question raised Biology is an experiment-based science. In middle school biology teaching, it is very necessary to cultivate students’ interest and practical abilities in studying biology and to strengthen experimental teaching. How to increase students’ chances of doing experiments on their own without increasing the burden on students or increasing the number of experimental equipment? We have arranged for students to experiment with experiments at home, A classroom with the second classroom to stimulate students’ curiosity, develop thinking, develop their practical ability. To this end, we randomly selected the first two (3) classes for comparative tests. (B) the test process and methods Test Grouping period mid-term examinations just ended, biological teaching and research group in the second year of grade two randomly selected the first two classes were tested subjects. The grade in the grade, academic performance at the middle level, normal style of study. Before the test, the class according to the seat order of each half of the series
