Empirical studies that focus on the impact of three-dimensional (3D) visualizations on learning are to date rare and inconsistent. According to the ability-as-enhancer hypothesis, high spatial ability learners should benefit particularly as they have enough cognitive capacity left for mental model construction. In contrast, the…

A series of pilot experiments were carried out to investigate the influence of stress induced by load and interference on the acquisition and retention of a path finding skill, and to investigate the relationship between two path finding strategies--retention of strings of instructions and understanding of global relationships--as components of…

The literature on learning research pertaining to the internal processing operations of the learner was reviewed. The current thinking of learning theorists regarding the nature and importance of these processes in learning and retention is described, and their significance for instructional technology is examined. Verbalization, imagery, and…
