摘　　要：认识有机化合物的性质,分析结构是关键。教学中以羰基——极性多重键为统领,以实验探究为情境,基于学科理解从中心原子杂化方式、成键原子电负性、共价键的极性等视角对酮羰基、醛基以及多羟基醛的性质进行深度教学,实现单官能团向多官能团及多官能团之间相互影响的认识进阶,在认知过程中促进学生化学学科理解能力与核心素养的发展。The analysis of the structure is the key to recognizing the properties of the organic compounds.Taking the carbonyl group:polar multiple bonds as the object of knowledge,based on the understanding of the chemistry principle,this paper presents the deep teaching about properties of ketone carbonyl groups,aldehyde groups and polyhydroxy aldehydes from perspectives of the hybridization form of central atom,the electronegativity of bonding and the polarity of the covalent bond in the unit teaching of aldehydes,ketones and glucose.The teaching process can help students achieve the progression of cognition from simple function group to multiple functional group and the interactions between multiple functional groups,and promotes the development of the students’academic literacy and core competencies.
