Exploring Scientific and Mathematical Thinking Skills in TIMSS

研究者将对第三次国际数学与科学研究（TIMSS）数据集应用专家知识和统计技术方法，以识别和测量学生必须使用的潜在能力，以获得测试问题的正确解决方案。TIMSS是在数学和科学领域进行的，但最终谈判的项目将只在数学领域进行。这项调查的目的是提供一种技术，可以帮助课堂教师和管理人员更好地利用考试成绩数据。研究者开发了一种技术（规则空间方法），可以在基础知识状态上创建一个尺度分数。这一过程将通过统计分析测试项目属性的存在性，以确定学生表现的认知处理技能和知识基础。

The investigator would apply a method of expert-knowledge and statistical technique to the Third International Mathematics and Science Study (TIMSS) data set to identify and measure latent competencies that students must use to get correct solutions to test problems. The TIMSS was conducted in both mathematics and science, but the final negotiated project will be conducted in mathematics only. The purpose of this investigation is to provide a technique that can help classroom teachers and administrators make better use of test score data. The investigator has developed a technique (Rule Space method) to enable the creation of a scale score on underlying knowledge states. This process will test through statistical analysis the existence of attributes of the test items that identify cognitive processing skills and knowledge underlying student performance.
