“…If the cognitive processing undertaken in working memory exceeds the available capacity, learning may be ineffective (Sweller, 1988). Research in CLT has provided a range of instructional design techniques aimed to support students learning, such as the worked example effect , problem completion effect (Renkl, Atkinson, & Grosse, 2004;Van Merriënboer, 1990), split-attention effect (Chandler & Sweller, 1991), modality effect (Tindall-Ford, Chandler, & Sweller, 1997), and the redundancy effect (Chandler & Sweller, 1994). These techniques support learning through reducing the processing of unnecessary information (extraneous load), whilst managing the inherent difficulty of the material (intrinsic load) and challenging learners to use working memory resources for processes that are relevant to learning (i.e., germane resources) (Sweller et al, 2011).…”
