Metacognitive problem solving: exploration of students’ perspectives through the lens of multi-dimensional engagement

Solving chemical problems entails content knowledge and mastery of problem-solving processes. However, students sometimes lack metacognitive processes required for problem solving in chemistry. This study investigated how first-year chemistry students engaged with the metacognitive problem-solving scaffold Goldilocks Help. Data was collected from an activity, which involved students reflectively comparing their problem-solving attempts to an expert solution. These comparative reflections (N = 373) were thematically analysed to investigate scaffold engagement in three dimensions: cognitive, emotional, and behavioural. Findings showed that scaffold use, coupled with self-reflection, allowed students to identify flaws in their solutions that were either problem specific or related to their problem-solving skills. Students were able to propose improvement strategies, such as posing prompting questions to themselves and finding multiple alternatives for evaluating an answer. Students, who initially lacked structured problem-solving skills, found that scaffolding helped them to slow down metacognitive processes that would otherwise be rushed through or engaged with on a surface level. Students’ resistance to the scaffold was due to fear of making a mistake or viewing the scaffold as requiring extra time and effort. Within a semester, many students demonstrated an improvement in successful and structured problem solving but some required more practice to internalise the scaffold. Our findings also indicated that students’ reflections on problem solving became more sophisticated as a result of continued exposure to the scaffold and iterative opportunities to compare their work to expert solutions, to self-assess, and to reflect. Further research on reflective writing in chemistry education should focus on the ipsative nature of such assessments, i.e. processes focusing on students’ own progress, growth, and improvement, compared to their previous performance, while recognising the power relations operationalised in course-embedded reflections. From the teaching practice perspective, having an awareness of students’ thoughts, emotions, and actions can help instructors differentiate between levels of student capabilities, mindsets, and needs for extra support, allowing teaching efforts to be directed at promoting metacognitive and structured problem solving.
