103524013_謝蕙如_Multimedia Learning

在進行多媒體學習時，教師在設計教材的時候要住避免超過學生的認知負荷。
而這篇paper除了介紹multimedia learning是甚麼之外，還根據了5種類型的認知負荷，提出了9種可以減少認知負荷的方法。

Type 1: Essential processing in visual channel > cognitive capacity of visual channel
method→Off-loading
Type 2: Essential processing (in both channels) > cognitive capacity
method→Segmenting、Pretraining
Type 3: Essential processing + incidental processing (caused by extraneous material) > cognitive capacity
method→Weeding、Signaling
Type 4: Essential processing + incidental processing (caused by confusing presentation) > cognitive capacity
method→Aligning、Eliminating redundancy
Type 5: Essential processing + representational holding > cognitive capacity
method→Synchronizing、Individualizing

並且在最後提出了可能遇到的挑戰。
