The present study investigated the effects on students’ learning experience of adding a video of a teacher to an e-learning module. A total of 43 undergraduates were asked to learn the content of a pedagogical document either with or without a teacher video on the screen. Although video captures of teachers are increasingly being integrated into online courses, few studies have investigated their impact and the best way of optimizing them. According to the social-cue hypothesis, the presence of a teacher (face and gestures) positively influences learners’ motivation and engagement in their learning. By contrast, the interference hypothesis holds that the teacher’s presence can lead to poor performances, as it acts as a source of visual interference that diverts students’ attention away from the relevant information. By assessing subjective ratings and learning outcomes, the present study tended to support the social-cue hypothesis, as it showed that adding a teacher video on screen significantly improved students’ retention of the spoken explanations, without disturbing either their performances on diagram and transfer problems or the time needed to process the document. Eye-tracking data showed that students spent 25% of their time watching the teacher video. Adding this video had no significant observable effects on the subjective ratings (i.e., social presence, evaluation of the teacher’s motivational skills, situational interest, cognitive load). These results suggest that videos of teachers can be used to improve social cues in multimedia learning without creating interference effects. 相似文献

The present study was intended to deepen current knowledge about the impact of graphic organizers (GOs) on students’ learning in a computer-based learning environment, by evaluating the effects of successive versus simultaneous presentation of a GO and an explanatory text. Based on the previous studies, we hypothesized that simultaneous display of a GO improves learning performances for the information it highlights (represented elements), but impairs those for nonrepresented elements, owing to a focused processing effect during text reading. We predicted that staggering the display of the document and the GO would avoid this effect and enhance the learning of both represented and nonrepresented elements. We compared three groups: students who studied a multimedia document without a GO (control group); students who viewed the same multimedia document accompanied by a GO that was displayed simultaneously (simultaneous GO group); and students who viewed the document and were then shown the GO (successive GO group). In line with previous research on GOs, results showed that adding a GO to the multimedia document increased students’ memorization of the represented elements and their comprehension. Interestingly, students in the successive GO group exhibited enhanced memorization of the nonrepresented elements and had the highest comprehension scores. These original results indicate that delaying the display of the GO can lead students to process the overall information more deeply and, in turn, improve their learning. 相似文献

When trained to associate Stimulus A to Stimulus B, humans can derive the untrained symmetrical B to A relation while nonhuman animals have much more difficulties. Urcuioli (2008, Journal of the Experimental Analysis of Behavior, 90, 257-–282; 2015, Conductal, 3, 4-–25) proposed that the apparent difficulty of animals in symmetry testing reflects their double encoding of the information on the stimuli (identity and relation) and their positional (i.e., spatial and temporal/ordinal) characteristics. This comparative study tested the emergence of symmetry in humans and baboons in a task in which the position of the stimuli was manipulated independently of their relation. Humans and baboons initially learned to associate pairs of visual shapes on a touch screen in a specific order. Three pairs of (A-B, C-D, and E-F) stimuli were used in training. After training, the two species were tested with the B-A, F-C, and E-D pairs. The B-A pairs preserved the association initially learned with A-B but reversed the positional information relative to training. The F-C pair neither preserved the association nor the positional information of the training pairs, and positional information were the only cues preserved in the E-D pair. Humans showed a response time advantage for B-A, suggesting symmetry, but also for E-D, suggesting that they also process positional information. In baboons, the advantage was found only for E-D, suggesting that they only process positional information. These results confirm that the processing of stimulus pairs differ between nonhuman animals to humans. 相似文献
