Effective vs. Efficient: Teaching Methods of Solving Linear Equations
Ivey, Kathy M. C.
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v3 p117-124
The choice of teaching an effective method--one that most students can master--or an efficient method--one that takes the fewest steps--occurs daily in Algebra I classrooms. This decision may not be made in the abstract, however, but rather in a ready-to-hand mode. This study examines how teachers solve linear equations when the purpose is pedagogical and when it is mathematical. Their answers reveal a definite preference for students to solve linear equations in a standard order even if it is not the most efficient way. The most efficient solutions show much more variation, but these answers still exhibit a clear tendency to follow the standard order in general. (Contains 2 figures and 2 tables.)
