An investigation of different instructional methods on number-concept understanding and arithmetic learning.

Made a 3-yr investigation of 3 different methods of teaching arithmetic to 1st-3rd grade children. The methods were: traditional, cuisenaire, and sets and numbers. No reliable differences in arithmetic achievement could be detected between Ss taught by the different methods. Also, no differences in number concept understanding were found, when assessed by a Piagetian-type of standardized test. Consistent differences between classes taught by the same method were found, but were attributed tentatively to differences in teaching ability.
