Algebraic word problem solving achievement test and strategies

The data are from the Algebraic word problem-solving achievement test, which tested the learners' problem-solving skills with Polya’s (1945) four-step problem-solving model. This is the most well-known mathematical problem-solving model, which is understanding the problem, devising a plan, carrying out the plan, and rechecking (Looking back). The data were analysed using the modified rubric from Charles (1987) and Sumaryanta (2015) based on Polya’s framework. 
The attached file also consists of the data on the problem-solving strategies used by the learners from Krulik and Rudnick (1996) when solving algebraic word problems. Interview data is included in the sheet. Pseudonyms were used on the interview transcribed data.

本数据集源自代数文字问题解决成就测试，旨在通过波利亚（1945年）提出的四步骤问题解决模型来评估学习者的解题能力。该模型是广为人知的数学问题解决模型，包括理解问题、制定计划、执行计划和回顾检查（反思）。数据分析采用了基于波利亚框架的查尔斯（1987年）和苏马兰塔（2015年）修订的评分标准。所附文件还包含了学习者解决代数文字问题时所采用的策略数据，源自克鲁利克和鲁德尼克（1996年）的研究，其中包含访谈数据。访谈转录数据中使用了化名。
