THE SPLIT‐ATTENTION EFFECT AS A FACTOR IN THE DESIGN OF INSTRUCTION
Abstract
S ummary . Cognitive load theory suggests that many conventional instructional formats are ineffective as they involve extraneous cognitive activities, which interfere with learning. The split‐attention effect provides one example of the consequences of inappropriate cognitive activities caused by poor instructional design. Learners are often forced to split their attention between and mentally integrate disparate sources of information (e.g., text and diagrams) before the instructional material can be rendered intelligible. This preliminary process of mental integration, while an essential precursor to learning, is likely to impose a heavy extraneous cognitive load. Physical integration (e.g., combining text and diagrams) may reduce cognitive load and so facilitate learning. This study reports findings from two experiments investigating the split‐attention effect. Using an engineering programming language (Numerical Control programming), the first experiment investigated the possible advantage of physically integrating text and diagrams. In a normal training environment, the integrated instructions group outperformed the conventional group. Experiment 2 was designed to see if the split‐attention effect would generalise to an area where mutually referring segments of text are conventionally separated, namely, empirical reports in psychology and education. In a laboratory study, Experiment 2 showed that students in an integrated group spent less time processing instructions ye…

“CLT emphasizes the need to integrate support for novice learners with the task environment fully; otherwise, split-attention effects increase extraneous cognitive load because learners have to integrate information mentally from the task environment with the given support (Chandler & Sweller, 1992;Sweller & Chandler, 1994).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
