What can be done to help college students who are not native speakers of English learn from computer‐based lessons that are presented in English? To help students access the meaning of spoken words in a slow‐paced 16‐minute narration about wildlife in Antarctica, a representational video was added that showed the scenes and animals being described in the narration (Experiment 1). Adding video resulted in improved performance of non‐native English speakers on a comprehension test (d = 0.63), perhaps because the video improved access to word meaning without creating extraneous cognitive load. To help students perceive the spoken words in a fast‐paced 9‐minute narrated video about chemical reactions, concurrent on‐screen captions were added (Experiment 2). Adding on‐screen captions did not improve performance by non‐native English speakers on comprehension tests, perhaps because learners did not have available capacity to take advantage of the captions. Implications for cognitive load theory are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

In a four-wave, cohort-longitudinal design with a community sample of 515 children and adolescents (grades 2 through 9), this study examined the longitudinal structure of and prospective interrelations between maladaptive cognitions and depressive symptoms. Multigroup structural equation modeling generated four major findings. First, the longitudinal structures of maladaptive cognitions and depressive symptoms consist of a single time-invariant factor and a series of time-varying factors. Second, evidence supported a model in which depressive symptoms predicted negative cognitions but not the reverse. Third, the time-invariant components of cognition and depression were highly correlated. Fourth, the strength of the depression-to-cognition relation increased with age. Implications regarding the mechanisms underlying clinical interventions with depressed children are discussed. 相似文献
