摘要： 本研究通过收集、分析被试解题时出声想的口语材料,探讨了初中学生解代数应用题中认知模式的作用和特点。在解代数应用题中,认知模式主要表现为识别应用题的类型。结果表明,被试能否识别类型在很大程度上决定着他能否迅速、准确地解答课题。要正确识别应用题类型,需要从课题的具体语义情境中分出确定的、一般的关系或结构。这种能力可以通过训练加以提高。训练所使用的材料应该具有多种变式。

Abstract: In our experiment we made a research on the role and peculiarity of recognition of patterns in solving applied algebrical problems of equation by the students of junior high schools.In solving these problems, the recognition of patterns appear mainly to be the differenciation of types of problems.The result shows that the subject's recognition of type of the problem determines whether he can solve it quickly and correctly or not.To recognize definitely the type of an applied problem, the student must abstract definite general relationships or structures from the concrete semantic context of the problem. This ability can be improved through drills with a variety of exercises.
