提出了一个明确地处理文字算术问题的文本理解和问题解决两个方面的加工模型。语篇加工理论的一般原理(van Dijk&Kintsch，1983)和关于理解问题语篇的语义知识的假设(Riley，Greeno，&Heller，1983)被结合在一个完整的问题理解模型中。该模型模拟了认知表征的结构，其中包括适合儿童使用的问题解决程序的信息。区分了几个信息处理步骤，并描述了不同级别的表示。该模型提供了对处理要求的分析，包括对不同类型问题的短期记忆的要求。根据这些加工差异对问题难度的预测通常与已报告的数据一致。
A processing model is presented that deals explicitly with both the text-comprehension and problem-solving aspects of word arithmetic problems. General principles from a theory of text processing (van Dijk & Kintsch, 1983) are combined with hypotheses about semantic knowledge for understanding problem texts (Riley, Greeno, & Heller, 1983) in an integrated model of problem comprehension. The model simulates construction of cognitive representations that include information that is appropriate for problem-solving procedures that children use. Several information-processing steps are distinguished, and various levels of representation are described. The model provides an analysis of processing requirements, including requirements for short-term memory that differ among types of problems. Predictions about difficulty of problems based on these processing differences are generally consistent with data that have been reported.
