A Specific Kind of Representation: How Systematics May Ease Cognitive Overload

Multiple representations are beneficial for meaningful understanding. However, three or more may add to the cognitive overload of students, if not in interactive diagrams and dynamic geometry. How a well-known representation consisting than 3 representational registers overcome problem without being too complicated. In this study, an old but well-structured that was used even over 40 years analyzed. The critical points function, asymptotes, x / y-intercepts, inflection points, graphing can be identified easily. It is prepared form table factors first derivative function second their roots indicate function’s increasing decreasing intervals its graph. This very systematic it acts like method draw graph with no-fault possible. Yet, besides many years, still courses Calculus, etc. We argue theory cannot alter due nature. content analysis, some examples shared via reader, qualitative aspects about Finally, systematicity, nature, nature reducing extraneous load emphasized. important thing here strategic lose sake new ones value already known discussed much.
