Some Reflections on Teaching Algebra through GeneralizationThis brief commentary chapter devoted to issues suggested by the Mason and Lee chapters raises a number of fundamental questions concerning generalization: the epistemological status of generalization and the nature and complexities of generalization as it is manifested in the didactic context of the algebra classroom.graphy 发表于 2025-3-25 09:46:51
The Role of Problems and Problem Solving in the Development of Algebrain an educational approach based on an oversimplified vision of algebra, which hides the semantic background of its grammar. In this chapter, some decisive factors in the evolution of the constitution of algebraic language are discussed in order to extract lessons from history that have a bearing on the teaching of this language today.水獭 发表于 2025-3-25 13:26:18
