An investigation of the impact of a social constructivist teaching approach, based on trigger questions, through measures of mental workload and efficiency

Social constructivism is grounded on the construction of information with a focus on collaborative learning through social interactions. However, it tends to ignore the human mental architecture, pillar of cognitivism. A characteristic of cognitivism is that instructional designs built upon it are generally explicit, contrarily to constructivism. This position paper proposes a novel learning task that is aimed at combining both the approaches through the use of trigger questions in a collaborative activity executed after a traditional delivery of instructions. To evaluate this new task, a metric of efficiency based upon a measure of mental workload and a measure of performance is proposed. The former measure is taken from Ergonomics, and two well know subjective self-reporting mental workload assessment techniques are envisioned. The latter measure is taken from an objective quantitative assessment of the performance of learners employing concept maps.
