化学是一门以实验为基础的学科,开展化学实验教学,能够帮助学生获得化学知识、掌握实验技能、培养实验能力。所以,它在初中化学教学中一直占据着非常重要的位置。但是,纵观如今的初中化学实验教学,多是以验证性实验为主,而且有着统一的实验要求、实验模式,内容也与社会实际相脱离,这就导致学生逐渐丧失了对实验学习的积极性和主动性。因此,有必要对当今的实验教学模式进行改进,使其符合学生心理特点和认识规律,并促使化学教学走上素质教育之路,于是,探究性实验便闯入视野。
Chemistry is an experiment-based discipline, chemical experiment teaching, to help students acquire chemical knowledge, master experimental skills, develop experimental ability. Therefore, it has always occupied a very important position in junior high school chemistry teaching. However, looking at today’s junior high school chemistry experiment teaching, mostly based on the confirmatory experiment, and has a unified experimental requirements, experimental mode, the content is also separated from the social reality, which led students gradually lost their enthusiasm for experimental learning And initiative. Therefore, it is necessary to improve the current experimental teaching mode to meet the psychological characteristics of students and the law of cognition, and to promote chemistry teaching embarked on the road of quality education, therefore, exploratory experiments broke into the field of vision.
