《普通高中生物课程标准(实验)》(以下简称《标准》)中指出在教学中创设类似于学术(或科学)研究的实践活动情景,通过学生自觉、主动发现问题,运用实验、调查操作、信息搜索与处理等手法,以表达、交流与合作等方式进行探索活动,获得知识与技能,体验实践中的过程与方法,发展其情感与态度,是提高生物课堂教学效率的有效途径。因此,在生物教学中应创设实践活动情景,以提高生物教学的效率。 “Ordinary High School Biology Curriculum Standards (Experiment)” (hereinafter referred to as the “Standards”) points out that in the teaching, a practice activity scene similar to academic (or scientific) research is created, through the students’ self-consciousness, active problem detection, and the use of experiments, investigations, and operations. Information search and processing methods, such as expression, communication and cooperation, etc., to carry out exploration activities, acquire knowledge and skills, experience the process and methods in practice, and develop their emotions and attitudes are effective ways to improve biology classroom teaching efficiency. Therefore, we should create practical activities in biology teaching to improve the efficiency of biological teaching.
