心理学专业的本科生被要求学习统计学，这是他们学位的主要组成部分之一，对许多人来说，这是课程中最具挑战性的方面。选修统计学入门课程的本科生参与了这项研究。根据他们第一次每周开卷测试的结果，分数在第50百分位及以下的学生被挑选出来，并被邀请参加一个预先测试，其中的问题涵盖了本学期的所有统计内容。使用预测试的结果，我们将55名参与者随机分配到精确教学SAFMEDS干预组（PT）（24名学生）或“照常治疗”组（TAU）（31名学生）。我们根据统计教材的学习指南制作了safmed卡片，并指导学生如何使用卡片以及如何绘制他们的学习表现。此外，参与者还被邀请参加每两周一次的与学生监考老师的会议，以审查个人进步并做出教学决定。结果表明，PT干预组学生在整个学期的所有周测中得分均高于TAU组，并且与TAU组相比，测试后表现取得了统计学上显著的提高，几乎相当于整个学位班的得分，F(1,53) = 5.23, p = 0.026, d = 0.62。
Psychology undergraduates are required to study statistics as one of the main components of their degree, and for many this is the most challenging aspect of the curriculum. Undergraduates taking an introductory statistics module participated in this study. Based on the results from their first weekly open-book test, students scoring at the 50th percentile and below were identified and invited to sit a pre-test of questions selected to cover all the statistical content for the semester. Using the results from the pre-test we randomly allocated 55 participants to either a precision teaching SAFMEDS intervention (PT) (24 students) or a “treatment as usual” (TAU) group (31 students). We made SAFMEDS cards with key statistical concepts taken from the study guide of the main statistics textbook and students were instructed how to use the cards and how to chart their learning performance. Additionally participants were invited to attend bi-weekly meetings with student proctors to review individual progress and make instructional decisions. Results indicated that those students in the PT intervention maintained a higher score than the TAU for all of the weekly tests through the semester, and achieved a statistically significant gain in post-test performance almost equivalent to an entire degree class score when compared with the TAU group, F(1, 53) = 5.23, p = .026, d = 0.62.
