Comparison of algorithmic and multiple-representation integrated instruction for teaching fractions, decimals, and percent

Investigations in Mathematics Learning

Using a 2 × 2 crossover design, the effect of the teaching treatments and their sequences on student performance were compared. Students in the MR/TA treatment sequence group received instruction in which multiple representations were integrated followed by traditional algorithmic instruction, and students in the TA/MR treatment sequence group received treatments in the reverse order. Participants included 89 seventh-grade students enrolled in a pre-algebra course in an urban middle school in the Midwestern United States. Results indicated gains in performance from both teaching treatments (MR and TA), however, statistically significant higher performance was found with the traditional algorithmic treatment. In terms of the order of teaching treatments, no significant performance difference was found.

Similarly, preservice teachers in the field of mathematics have to cope with the mastery or reinforcement of the conceptual knowledge for teaching the discipline (Hill, Ball, Schilling (2000), and the procedural including the pedagogical expertise to better service American schools. This study analyzes how preservice teachers enrolled in college-based math methods program demonstrate two domains within pedagogical content knowledge applied to teaching elapsed time concepts via video assessments (Stigler, Gallimore & Hiebert, 2000) in the context of reform math methods course.

Results indicated no significant differences in perceived mental effort and student achievement however, a significant difference was found in regard to tutorial study time.

Two treatment groups were compared. MR first received multiple representation instruction followed by traditional algorithmic instruction and TA first received these teaching approaches in reverse order. Participants included 43 seventh grade students from an urban middle school in Midwestern USA. Results indicated gains in knowledge from both treatment groups; however, the differences between groups were nonsignificant. Comparisons of effect size however, indicated larger growths in abilities to solve among students who received multiple representation instruction first. In addition, statistical differences between on-task behaviors were found in favor of the traditional algorithmic approach.

Two versions of the tutorial were developed; adaptive and non-adaptive. A total of 134 undergraduate students were randomly assigned to adaptive (n=74) or non-adaptive (n=60). Our results revealed that the adaptive group had a significantly higher knowledge gains than the non-adaptive group.
