In secondary school philosophy classes students learn to reason critically about social and scientific issues. This study examined the effects of a whole-class, teacher-led philosophy classroom dialogue intervention on students’ value-loaded critical thinking. Value-loaded critical thinking is logically consistent, self-reflective reasoning focused on making moral value-judgments about what is right to believe or do. In a quasi-experimental study (N = 437 students) with a pre-test post-test design, we investigated whether engaging in classroom dialogues in which the teachers implemented five design principles for promoting value-loaded critical thinking and transfer thereof, positively affected students’ (n = 150) value-loaded critical thinking in transfer tasks. The results were compared to two comparison conditions: students (n = 149) who participated in regular teacher-led philosophy classroom dialogues and students (n = 145) who followed a regular 10th-grade curriculum without philosophy classes. Results showed that students in the intervention condition outperformed students in both comparison conditions on referring to moral values. Regarding critical reasoning, we only found significant effects compared to the students who followed the regular 10th-grade curriculum. Findings indicate that a specifically designed dialogic intervention can enhance students’ capacities in value-loaded critical thinking.

Metacognition comprises both the ability to be aware of one’s cognitive processes (metacognitive knowledge) and to regulate them (metacognitive control). Research in educational sciences has amassed a large body of evidence on the importance of metacognition in learning and academic achievement. More recently, metacognition has been studied from experimental and cognitive neuroscience perspectives. This research has started to identify brain regions that encode metacognitive processes. However, the educational and neuroscience disciplines have largely developed separately with little exchange and communication. In this article, we review the literature on metacognition in educational and cognitive neuroscience and identify entry points for synthesis. We argue that to improve our understanding of metacognition, future research needs to (i) investigate the degree to which different protocols relate to the similar or different metacognitive constructs and processes, (ii) implement experiments to identify neural substrates necessary for metacognition based on protocols used in educational sciences, (iii) study the effects of training metacognitive knowledge in the brain, and (iv) perform developmental research in the metacognitive brain and compare it with the existing developmental literature from educational sciences regarding the domain-generality of metacognition.
