生物学是一门实验性学科,实验是生物学的需要组成部分,实验教学的开展有主于学生知识水平的提高,学习兴趣的培养,更有助于学生更好地认识世界,感知世界,特别是生物演示实验在中学生物学教学中有着重要的作用。首先,生物学实验是探究性学习的一种重要途径。生物学的学科特征决定了生物学实验可以作为探究性学习的途径;生物学实验本身就是科学探究的过程;生物学实验为探究性学习中验证假说提供了科学方法;其次,生物学实验作为探究性学习的教学策略引导学生改进教学实验;变验证性实验为探究性实验;指导学生设计探究性实验;开放实验室,让学生完成探究性实验;改革实验教学评价方法。
Biology is an experimental discipline, and experiment is an integral part of biology. The development of experimental teaching mainly focuses on improving the students’ knowledge and cultivating their interest in learning. It also helps students to better understand the world, perceive the world, In particular, biological demonstration experiments play an important role in high school biology teaching. First of all, biological experiments is an important way to explore learning. Biology disciplines determine the biological experiment can be used as a way of inquiry learning; biology experiment itself is the process of scientific inquiry; biology experiment provides a scientific method for the hypothesis of inquiry learning; secondly, biology experiment as inquiry Teaching strategies of sexual learning guide students to improve teaching experiments; change confirmatory experiments for exploratory experiments; guide students to design exploratory experiments; open laboratories to enable students to complete exploratory experiments; and reform experimental teaching evaluation methods.
