基于PCK理论的高中化学教学实践研究--以“最简单的有机物甲烷”为例

On High School Chemistry Teaching Practice Based on PCK Theory--Taking the Simplest Organic Compound,Methane as an Example

PCK理论是指将教师的学科知识与教育学知识结合在一起运用于教学实践能解决教师“缺失范式”问题的理论.运用PCK教学理论协助教师在授课过程中培养学生核心素养,达到培养人才的目的.根据化学教师PCK特点,提出基于一个学科主题和五条PCK主线(知识线、素养线、策略线、兴趣线和评价线)的教学设计与实践模式并进行实践.以“最简单的有机物甲烷”为例,设计基于这一学科主题的PCK教学设计并进行教学实践研究,发现能够得到较好的教学效果.

PCK Theory indicates that combining teachers'subject knowledge and pedagogy knowledge into teaching practice can effectively solve the problem of teachers'"missing paradigm".Using PCK teaching theory to cultivate students'core qualities in the teaching process,so as to achieve the purpose of cultivating talents.According to the characteristics of PCK of chemistry teachers,a teaching design and practice mode based on a subject theme and five main lines of PCK(knowledge line,accomplishment line,strategy line,interest line and evaluation line)was proposed and practiced.Taking"the simplest organic methane"as an example,the PCK teaching design based on this subject theme was designed and the teaching practice was studied.It was found that better teaching effect could be obtained.
