The article adopts the literature research method and text analysis method, based on the APOS theory, to carry out the teaching design of the exponential function concept, aiming at helping students to go through the four phases of “activity, process, object, schema” to deeply understand the knowledge and actively construct the knowledge. Finally, it is proposed that in conceptual teaching, teachers should focus on introducing concepts into life, emphasizing students’ subjectivity in learning and the constructiveness of the knowledge system.展开更多

The results indicate that the altruism/corporate group model describes the intergenerational support behavior in current rural families better, and the needs of parents are significant effects on the intergenerational support of the children.展开更多
