Project SEED (Special Elementary Education for the Disadvantaged) is a supplementary mathematics program which applies Socratic discovery methods to mathematics instruction. It was implemented in 10 fourth- and fifth-grade classrooms in Portland to improve mathematics achievement and increase students' esteem for mathematics learning. Student achievement growth for the SEED groups was mixed. Four classes made gains greater than the district average, four classes neither gained nor lost, and one class gained less (data from the 10th class are not included). No significant correlations were found between achievement and length of time in the project. Student attitudes did not change significantly; nearly 70% were positive both before and after SEED. The implementation plan was difficult to accomplish, and the SEED curriculum was not integrated with the district's mathematics program. Observations indicated that students were introduced to some elements of exponentiation and were involved in enjoyable classroom activities. It was recommended that SEED be considered as an extracurricular enrichment program. (MNS)
