{{hidden|'''Effective Use of Graphs- Stern, Aprea and Ebner, 2006.'''|Graphs are an integral part of teaching economic concepts, but can be ineffective if not used properly. Stern, Aprea and Ebner looked at how people can use graphs to transfer knowledge from one topic in economics to another. In their studies, participants first learned about stockkeeping in one of three ways. The first group was shown text and a graph about the topic, but did not have to engage with the graph. The second group were shown text and learned how to construct a linear graph about this topic through a set of instructions. A control group merely received text about the topic. Then, all the participants had to process a text and answer questions regarding a different economics topic, revenue functions and break-even points of companies. The questions could easily be answered through the construction of a linear graph similar to the one shown to the first two groups. The study found that groups who actively engaged in drawing graphs about stockkeeping  performed better on later questions, particularly if they drew a graph to answer the questions about revenue functions. This study presents strong support for the practice of requiring students to draw graphs to illustrate theories rather than merely asking them to describe the theories in words.

Many instructors use multimedia, including presentation tools such as Microsoft PowerPoint, in the classroom to hold students' attention and to streamline class preparation. Here is what the latest research tells us about the effective use of multimedia presentations:

alt text


  • Avoid duplication. Research by Jamet and Le Bohec in 2006 showed that presenting students with a Powerpoint presentation that directly mirrored the instructor's lecture resulted in lower information recall on multiple types of tests.
  • Concise is better. Research in 2003 by Bartsch and Cohern showed that elaborate PowerPoint features such as unrelated images, sounds, and extraneous information impaired student learning.
  • Draw graphs in class. Research in 2003 by Stern, Aprea and Ebner showed that groups presented with a graph that was ‘actively illustrated’ performed better in recall tasks than groups passively presented with the same graph. 'Actively illustration' is when students are asked to develop a graph themselves rather than merely having a graph shown to them.

"9 Ways to Reduce Cognitive Load in Multimedia Learning" (Mayer & Moreno, 2003)

Mayer and Moreno propose a theory of multimedia learning and cognitive overload based on 3 assumptions. Cognitive overload is a term used in cognitive psychology to describe the overwhelming effects of a large amount of information on a person's working memory. Mayer and Moreno's theory involves three assumptions about cognitive overload. The first is called the dual-channel assumption and says that humans process verbal and visual in separate systems. The second, the limited-capacity assumption, argues that a limit exists as to the amount of information each system can process at any given time. Lastly, the active-processing assumption says that meaningful learning represents necessitates higher cognitive processes such as building connections between verbal and visual representations of information. Oftentimes, multimedia presentations bombard students with text, pictures, and audio all at the same time. If the assumptions in Mayer and Moreno's theory hold, multimedia learning may present a challenge to student's mental capacity, particularly for students who are not strong visual and/or verbal learners. The authors propose several ways of alleviating Cognitive Overload here: "9 Ways to Reduce Cognitive Load in Multimedia Learning" (Mayer & Moreno, 2003).

Conclusion

Multimedia should serve as a guide to lecture, not compete with the teacher. This means that teachers have to be careful to not only keep student attention, but also make smart multimedia decisions to ensure every minute of lecture is transmitting information to the student in an efficient, engaging way.
