核心概念的教学是生物学教学的重要任务。影响概念形成的主要因素及其相互关系是科学教育研究工作者最为关注的对象。然而,对于哪种影响因子对概念形成的作用最大,一直以来没有定论。本工作应用通径分析的方法对影响概念形成主要因子的作用及其相互关系进行了分析。结果表明:对概念形成起作用的总效应的排名是,学生学习能力、概念难度、学生认知活动水平及教学水平。教师教学要以提高学生的学习能力为首要目标,提高学生的学习能力才是解决学习问题的根本路径。
The teaching of core concepts is an important task in biology teaching. The main factors influencing the formation of concepts and their interrelationships are the objects of most concern to researchers in science education. However, there has been no conclusion as to which impact factor has the greatest effect on concept formation. In this work, we use the method of path analysis to analyze the role of influencing the formation of the main factors of the concept and their mutual relations. The results show that the rankings of the total effect on the formation of concepts are the students ’ability to learn, the concept of difficulty, the level of students’ cognitive activity and their teaching level. Teachers teaching to improve students ’learning ability as the primary goal, to improve students’ learning ability is the fundamental way to solve the learning problems.
