摘要:生物学是一门实践性很强的学科,随着新课改的进行,实践类活动越来越受到重视,本课题通过对人教版高中生物中的各种实践类活动的案例进行分析,以促进实践类活动更好地开展。

   本文通过案例分析法从案例中的活动步骤、细节、选材等方面分析各个案例的优缺点。其中包括演示实验案例、验证实验案例、探究实验案例、问题讨论案例各一个,调查案例两个。经分析比较案例发现,实践类活动存在以下优点:①活动中用创新材料替代传统材料效果更好。②实验类实践活动让学生自主探究,能更好的发挥学生的自主性。但开展实践类活动又存在两个问题:①不开展。教师用传统的讲授法代替实践类活动。②不充分。教师没有完全放手让学生自主探究,而设定特定的探究课题。

   本文还旨在为高中教师进行课堂教学提出建议。

Abstract:Biology is a very practical subject. With the new curriculum, practical activities are paid more and more attentions. The purpose of this issue is to promote better practice to carry out practical activities by analysing a variety of practical activities cases,which are on the PEP of high school biology. 

   This article aims at analysing the advantages and disadvantages of each case by studying the activity steps, details, material selecting and other aspects. Including one demonstration experiment case, one validation experiment case, one inquiry experiment case, a discussion case and two survey cases, there are totally six cases. After analysing and comparing these cases, I found that practice activities exist in the following advantages: (1) The influence is better , if we replace the traditional materials with innovative materials. (2) The practical activities make students explore independently. And it can better exert students' autonomy. But to develop practice activities there are two problems: (1) Not carry out. Teachers using the traditional teaching method instead of practical  activities. (2) Not sufficiently. Teachers do not fully let students explore independently. They prefer setting a specific topic.

    This article also aims at providing high school teachers' teaching level.
