Students' Perceptions About a Metacognitive Activity Involving the Concept of the Amount of Substance

Abstract

The amount of substance, that has the mole as a unit, is a concept that has been causing learning problems for both students and for teachers. This article aims to present students' impressions of a metacognitive activity involving the concept of amount of substance. The data were collected during a case study carried out with 10 students from a popular preparatory course for the entrance exam, which at the end of the participation in the activity provided their impressions through text and verbally during a group discussion. The data were analyzed in the light of the content analysis and the results suggest that the metacognitive strategy used favors the performance of activities because the use of the table stimulates conscious self-regulation while the investigative molds proposed during the activity increase students' motivation.
