【摘要】：线索在多媒体学习中作为一种重要的教学设计形式,具有引导注意、组织和整合信息的功能。综述已有研究发现,线索具有引导学习者加工特定位置信息、忽视无关信息干扰的功能;在特定条件下帮助学习者整合图-文信息,并且提高学习者的学习效果;但对于线索信息组织功能尚缺少充分而有力的证据。关于线索对学习效果的影响,大部分研究证实线索能够促进学习。但是由于线索的多样性以及学习材料的复杂性,线索能否有效地提高学习效果仍然存在争议。从认知负荷理论视角综述发现,线索加入并没有明显降低学习者感知到的主观认知负荷;从知觉加工视角而言,线索作为突显的刺激会吸引学习者的注意,从而简化学习者在知觉加工阶段的视觉搜索。未来研究仍然需要关注以下问题:(1)线索是否真的被学习者所注意和加工?(2)重视学习材料多样性比较和不同线索类型差异探讨,(3)关注学习者经验影响,(4)如何在教学设计上保证线索的有效性。
[Abstract]:As an important teaching design form in multimedia learning, clue has the functions of guiding attention, organizing and integrating information. It is found that cues have the function of guiding learners to process specific location information, ignoring the interference of irrelevant information, helping learners to integrate graph and text information under certain conditions, and improving learners' learning effect. However, there is still a lack of sufficient and effective evidence for the function of clue information organization. As to the effect of cues on learning effect, most studies have proved that cues can promote learning. However, due to the diversity of clues and the complexity of learning materials, whether clues can effectively improve the learning effect is still controversial. From the perspective of cognitive load theory, it is found that clue addition does not significantly reduce the perceived subjective cognitive load of learners, and from the perspective of perceptual processing, cues as a prominent stimulus will attract learners' attention. In order to simplify the learners in the perceptual processing stage of visual search. Future research still needs to pay attention to the following questions: (1) whether clues are really paid attention to and processed by learners? (2) pay attention to the diversity of learning materials and explore the differences between different cues, (3) pay attention to the influence of learners' experience, (4) how to teach in teaching The design ensures the validity of the clue.
