Design of Mathematical Homework Chain from the Perspective of Learning Progression
There are problems in current homework design in primary and secondary schools,such as fragmentation and high quantity but low quality,leading to heavy burden for students.Learning progression is a model that can describe students'thinking and cognitive development and has the teaching direction of"big perspective""conceptual structure dominance""hierarchical setting and transformation"and"multiple accompanying evaluation".Reviewing and instructing homework design from the perspective of learning progression,we can obtain chain-structure homework design orientation of overall architecture,targeted objective,hierarchy transformation and evaluation accompaniment.Based on this,we can formulate chain-structure homework pattern and construct a mathematical unit homework chain-structure design model that includes three processes:the establishment of core concept structure diagram,the construction of chain-structure homework target hierarchy,and the development of chain-structure homework content.
