This study is part of a broader study on algebraic reasoning in elementary education. The research objective of the present survey, namely to describe generalization among second grade (7- to 8-year-old) students, was pursued through semi-structured interviews with six children in connection with a contextualized generalization task involving the function y = x + 3. Particular attention was paid to the structures recognized and the type of generalization expressed by these students as they reasoned. In all six, we observed three phases of inductive reasoning: (a) abductive, (b) inductive and (c) generalization. The students correctly recognized the structure at least once during the interview and expressed generalization in three ways.

二年级学生的概括过程

该研究是基础教育中代数推理的更广泛研究的一部分。本次调查的研究目标，即描述二年级（7至8岁）学生的概括性，是通过对六个孩子的半结构化访谈进行的，涉及涉及函数y = x的上下文化概括性任务+ 3.特别注意这些学生在推理过程中认可的结构和表达的概括类型。在所有六个方面，我们观察到归纳推理的三个阶段：（a）归纳推理，（b）归纳推理和（c）概括。学生在面试中至少正确地认识了一次结构，并以三种方式表达了概括。
