tandfonline.com – Using Visual Representations to Enhance Students’ Understanding of Causal Relationships in Price

ABSTRACT

This study investigates how different visual representations of price facilitate learning in upper secondary social science education. Three lessons on pricing were given to four classes (n = 94 students). Two classes had lessons based on graphs and two on a causal loop diagram. Written pre- and post-test answers were analysed phenomenographically and results arising from the two visual representations were compared. Results suggested that a causal loop diagram facilitated a more complex way of understanding the causal relationships in pricing than the graph. The traditional way of introducing price, through the use of supply/demand graphs, is thereby problematised. The study extends knowledge by identifying a synergy between phenomenography and research on visual representations and has specific implications for teaching and learning.

Jeg har tidligere været ansat som pædagogisk konsulent i matematik og tysk hos UCL ved Center for Undervisningsmidler (CFU) i Vejle og lærer i udskolingen (7.-9. klasse) på Lyshøjskolen i Kolding. Jeg er ejer af og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk og er tidligere fagredaktør på matematik på emu.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
