Can Exploratory Learning Help to Close the Minority Achievement Gap?

Underrepresented minority (URM) students are disproportionately retained and underperform in STEM disciplines compared to non-URM students, yet are needed in the STEM workforce. Possible causes of this minority achievement gap are social isolation, “chilly” classrooms, low confidence, and stereotype threat (Ballen et al., 2017). Inclusive instruction, which includes active learning, may help to reduce this gap (Saunders & Kardia, 1997). Active learning engages students in learning through activities and/or discussion in class as opposed to passively listening to lectures (Brame, 2016; Freeman et al., 2014). But, not all active learning strategies promote inclusive learning environments. We examined whether a type of active learning activity called exploratory learning helps to reduce the minority achievement gap. Students (N = 356) in an introductory psychology statistics course or recruited for a lab study were randomly assigned to learn concepts of variance and standard deviation in one of two conditions. Students in the explore-first (EF) condition completed a novel problem followed by instruction. Students in the instruct-first (IF) condition received instruction followed by the problem, akin to a traditional learning sequence. All participants completed a posttest approximately one week later, or immediately after the first packet in the lab. Although posttest scores improved overall in the EF compared to the IF condition, a minority achievement gap was found in both conditions. Exploratory learning can be an effective method overall, but did not decrease the minority achievement gap.https://ir.library.louisville.edu/uars/1029/thumbnail.jp

Enclothed Cognition and Controlled Attention during Insight Problem-Solving

Individual differences in working memory capacity (WMC) increase the ability, and tendency, to devote greater attentional control to a task—improving performance on a wide range of skills. In addition, recent research on enclothed cognition demonstrates that the situational influence of wearing a white lab coat increases controlled attention, due to the symbolic meaning and physical experience of wearing the coat. We examined whether these positive influences on attentional control lead to negative performance outcomes on insight problem-solving, a task thought to rely on associative processes that operate largely outside of explicit attentional control. Participants completed matchstick arithmetic problems while either wearing a white lab coat or in a no-coat control condition. Higher WMC was associated with lower insight problem-solving accuracy in the no-coat condition. In the coat condition, the insight problem-solving accuracy of lower WMC individuals dropped to the level of those higher in WMC. These results indicate that wearing a white lab coat led individuals to increase attentional control towards problem solving, hindering even lower WMC individuals from engaging in more diffuse, associative problem-solving processes, at which they otherwise excel. Trait and state factors known to increase controlled attention and improve performance on more attention-demanding tasks interact to hinder insight problem-solving

Exploratory Learning Using Consistency Problems: Activity Type Matters

Studies have shown that exploration before instruction can improve learning. Students (N= 197) from the psychology participant pool were taught the concept and procedure of standard deviation in one of four conditions. Students were given both direct instruction and a problem to solve in one of two orders: instruction-first, or exploration-first. During the problem-solving activity, students were asked to determine the consistency of a set of numbers. This dataset was set up as a rich dataset, or to highlight contrasting cases. Students then completed a posttest. We compared mean posttest scores to find that exploration before instruction led to better understanding when using contrasting cases, but not a rich dataset. Exploring before instruction is benefited when students are helped to discern the key features of the problems, using contrasting cases.https://ir.library.louisville.edu/uars/1018/thumbnail.jp

Bringing exploratory learning online: problem-solving before instruction improves remote undergraduate physics learning

STEM undergraduate instructors teaching remote courses often use traditional lecture-based instruction, despite evidence that active learning methods improve student engagement and learning outcomes. One simple way to use active learning online is to incorporate exploratory learning. In exploratory learning, students explore a novel activity (e.g., problem solving) before a lecture on the underlying concepts and procedures. This method has been shown to improve learning outcomes during in-person courses, without requiring the entire course to be restructured. The current study examined whether the benefits of exploratory learning extend to a remote undergraduate physics lesson, taught synchronously online. Undergraduate physics students (N = 78) completed a physics problem-solving activity either before instruction (explore-first condition) or after (instruct-first condition). Students then completed a learning assessment of the problem-solving procedures and underlying concepts. Despite lower accuracy on the learning activity, students in the explore-first condition demonstrated better understanding on the assessment, compared to students in the instruct-first condition. This finding suggests that exploratory learning can serve as productive failure in online courses, challenging students but improving learning, compared to the more widely-used lecture-then-practice method
