The Role of Schemes in Designing Computerized Environments.
Peer reviewed Peer reviewed
Hershkovitz, Sara; Nesher, Pearla – Educational Studies in Mathematics, 1996
Comparison of the effectiveness of two computerized environments, Schemes for Problem Analysis (SPA) and Algebraic Proposer (AP), with two sixth-grade classes found that in solving easy word problems, both software systems were equally helpful, but in harder word problems, those students who learned with SPA experienced more success than those who…

The Role of Schemes in Two-Step Problems: Analysis and Research Findings.
Peer reviewed Peer reviewed
Nesher, Pearla; Hershkovitz, Sara – Educational Studies in Mathematics, 1994
Studied schemes involved in solving two-step arithmetic word problems in (n=1824) elementary schoolchildren in Israel. Compound schemes and combinations of operations were found to affect the difficulty level of the problems. Appendix includes two versions of the test instrument. (Contains 17 references.) (MKR)
