The purpose of the study was to examine the effects of instruction given with different multimedia modalities (written text + animation or narration + animation) on the academic achievement, cognitive load, and positive affect in different paces (learner-paced or system-paced); 97 freshmen university students divided into four groups taught in…

This study investigates the effects of using both specific labels and diagrammatic arrows in the animation of salt dissolution. Four different versions of the animation served as treatments that were developed based upon principles of educational technology and cognitive psychology. The researchers studied the effects of spatial ability (high or…

The point of Choi and Clark (2006) was that after many well-designed studies, they have no evidence for either the learning or the motivational benefits of pedagogical agents. In their study, they found compelling evidence that when agents are found to enhance learning, a less expensive and less distracting pedagogical method has equal or greater…

Choi and Clark (2006) argue that learning is attributed to the instructional method rather than the specific medium used to deliver instruction (i.e., the pedagogical agent). Additionally, they consider pedagogical agents as unnecessarily expensive tools, whose instructional affordances can be replicated by less expensive options. In this response…

Reports the use of two different visual-control treatments (self-controlled versus system-imposed) among students with different cognitive styles (Field Independent and Field Dependent). Eighth-grade students were tested to determine how they learned from different design approaches of animated instructional materials. Effect of visual control was…

A "science of e-learning" involves the scientific investigation of how people learn in electronic learning environments. Three elements of a science of e-learning are: a) "evidence"--a base of replicated findings from rigorous and appropriate research studies; b) "theory"--a research-based theory of how people learn in electronic learning…
