摘要:

在两个早期的研究中,我们开发了一种新的方法来衡量学生的能力转移物理问题解决技能到新的情况下,使用一系列的在线学习模块,并实施了两个干预措施的形式,旨在提高迁移能力的额外的学习模块。本文介绍了一种新的数据分析方案,该方案可以通过解释学生目标定向和行为的可能差异来提高测量的准确性,并揭示两种干预措施之一提高迁移能力的可能机制。基于二乘二的自我调节学习框架,具有成绩回避目标的学生更可能猜测一些评估尝试,以节省时间,导致低估了学生群体的迁移能力。目前的分析表明,大约一半的学生有频繁的简短的初步评估尝试,并显着降低某些模块的正确率,我们认为这可能是起源至少部分来自学生采取的性能回避策略。然后,我们对剩下的人群进行了划分,我们可以肯定的是,很少有学生采取了回避策略,这是基于他们是否与旨在发展基本问题解决技能的干预模块进行了互动,或者在第一次尝试时通过了该模块而没有与教学材料进行互动。通过与前一学期的倾向评分匹配人群进行比较,我们发现,在以前的研究中观察到的后续迁移表现的改善主要来自后者,这表明干预措施可以有效地提醒学生激活现有技能,但在尚未掌握这些技能的人中,这些技能的发展不足。

英文摘要:

In two earlier studies, we developed a new method to measure students' ability to transfer physics problem solving skills to new contexts using a sequence of online learning modules, and implemented two interventions in the form of additional learning modules designed to improve transfer ability. The current paper introduces a new data analysis scheme that could improve the accuracy of the measurement by accounting for possible differences in students' goal orientation and behavior, as well as revealing the possible mechanism by which one of the two interventions improves transfer ability. Based on a two by two framework of self-regulated learning, students with a performance-avoidance oriented goal are more likely to guess on some of the assessment attempts in order to save time, resulting in an underestimation of the student populations' transfer ability. The current analysis shows that about half of the students had frequent brief initial assessment attempts, and significantly lower correct rates on certain modules, which we think is likely to have originated at least in part from students adopting a performance-avoidance strategy. We then divided the remaining population, for which we can be certain that few students adopted a performance-avoidance strategy, based on whether they interacted with one of the intervention modules designed to develop basic problem solving skills, or passed that module on their first attempt without interacting with the instructional material. By comparing to propensity score matched populations from a previous semester, we found that the improvement in subsequent transfer performance observed in a previous study mainly came from the latter population, suggesting that the intervention served as an effective reminder for students to activate existing skills, but fell short of developing those skills among those who have yet to master it.
