In a previous study, DeLeeuw and Mayer (2008) found support for the triarchic model of cognitive load (Sweller, Van Merriënboer, & Paas, 1998, 2019) by showing that three different metrics could be used to independently measure 3 hypothesized types of cognitive load: intrinsic, extraneous, and germane. However, 2 of the 3 metrics that the…

A rising number of (online) learning scenarios feature video-based worked examples. We analyzed the effects of the presentation mode of worked examples on their effectiveness and efficiency in two experiments with university students (N[subscript 1] = 57; N[subscript 2] = 43). The students acquired argumentation knowledge by self-explaining…

This study examined how 2 kinds of help when learning from text and pictures (mapping support and instructional guidance through prompts) influence the coherence formation process of integrating information into a mental model. It also explored spatial abilities and working memory span as potential moderators. In a computer-based setting, 84…

Analysis showed that a word problem is difficult to solve if: it is of a different type from the problem that preceded it; its solution requires a large number of different operations; its surface structure is complex; it has a large number of words; or it requires a conversion of units. (Authors)

Focused on the effects of difficulty level and choice of difficulty level on the engagement of students working CAI (computer-assisted instruction) math problems, possible patterns of student choices, and the relationship of locus of control measures to choice of difficulty levels. (Author/BJG)
