在高中化学教学中,传统的应试教育思想占有着相当大的比重,机械式传授和“填鸭式”教学模式充斥在课堂中,学生的创新意识以及实践能力被完全忽视,思维模式始终处于一个封闭状态,学生的学习能力下降、创新能力不足现象屡见不鲜。新课程改革要求教师要依照《普通高中化学课程标准》,注重学生的情感、态度以及价值观“三维目标”的落实,来进行高中化学教学的组织与设计。从探究性学习的具体内涵出发,以高中化学“乙酸的酸性”为课堂案例来进行教学设计探究,并对探究学习中教师所扮演的角色做一些简要说明。
In high school chemistry teaching, the traditional examination-oriented education holds a large proportion. Mechanical teaching and “spoon-feeding” teaching model are all in the classroom. Students’ innovative awareness and practical abilities are completely ignored. The thinking mode is always at A closed state, students learning ability decline, lack of innovation is not uncommon phenomenon. The new curriculum reform requires that teachers should organize and design chemistry teaching in senior high schools according to the “General High School Chemistry Curriculum Standards” and pay attention to the students’ feelings, attitudes and values “three-dimensional goals”. Based on the specific connotation of inquiry learning, this paper takes the case study of senior high school chemistry “acidity of acetic acid ” as a case study to make a brief introduction to the role of teachers in inquiry learning.
