The MAMMS Project: Measuring and Addressing Middle-Grades Misconceptions in Statistics

这个为期3年的项目最初提交给ITEST计划，但被认为更适合DRK-12评估链。该项目旨在开发诊断评估，以确定具体的统计误解（数据集作为实体，比较数据集，过度依赖平均程序），教师教程，以支持和加强教师？这些概念和误解的理解，活动，让学生在统计推理的应用，包括补充活动的个性化教学，和有效性试验，以评估对学生的资源的影响？统计知识和影响。他们将使用认知实验室来解决有效性和随机对照试验来解决初始疗效。教师活动前辅导和学生活动将免费公开。

This 3 year project was initially submitted to the ITEST program, but was deemed more appropriate to the DRK-12 assessment strand. The project seeks to develop diagnostic assessments to identify specific statistical misconceptions (datasets as entities, comparing datasets, and overreliance on the mean procedure), teacher tutorials to bolster and reinforce teachers? understandings of these concepts and misconceptions, activities to engage students in applications of statistical reasoning including supplemental activities for individualized instruction, and an efficacy trial to evaluate the effect of the resources on students? knowledge and affect in statistics. They will use cognitive labs to address validity and a randomized control trial to address initial efficacy. Teacher pre-activity tutorials and student activities will be made freely and publicly available.
