Abstract | Reported are suggestions indicated by research studies to eight questions concerning the teaching of rational numbers. (1) Can young children learn fractional concepts? Answer: Manipulative materials are of value to learning in the primary grades. (2) How should the common denominator be determined? Answer: Both factoring and equivalent fractions are good. (3) Does error analysis help? Answer: Identification and correction of specific errors should yield greater achievement. (4) How should we teach multiplication? Answer: No conclusion. (5) How should we teach division? Answer: Inversion and reciprocal algorithms seem most effective. (6) What other things affect achievement? Answer: Manipulative materials, practice and meaningful teaching all help. (7) Should decimals, fractions, and place value be related? Answer: Yes, these concepts should be associated. (8) How should we teach placement of the decimal point when dividing? Answer: Greater accuracy results from the "multiplication by a power of ten" approach. (RS) |
