小学教育专业“基础化学-倾向生活化学”教学探索与实践

doi:10.3866/PKU.DXHX202110048

Abstract

Abstract:

Curriculum teaching and reform should integrate knowledge renewal and focus on professional training objectives to truly implement the teaching to the desired points. Therefore, we reconstructed the curriculum contents by integrating basic chemistry knowledge into daily life when teaching "basic chemistry" in primary education specialty. In addition, we provided students with practice opportunities by building experimental platform and paid attention to cultivate the accomplishments of students in carrying out science education activities. These measures have achieved good teaching effects.

Key words: Basic chemistry, Life chemistry, Primary education specialty, Teaching practice
