Achievement in Writing Geometry Proofs.
Senk, Sharon L.
In 1981 a nationwide assessment of achievement in writing geometry proofs was conducted by the Cognitive Development and Achievement in Secondary School Geometry project. Over 1,500 students in 11 schools in 5 states participated. This paper describes the sample, instruments, grading procedures, and selected results. Results include: (1) at the end of the year approximately half the students in courses teaching proof can do more than trivial proofs; and (2) there are no sex-related differences in proof-writing achievement. Relations between proof-writing achievement and both the van Hieles' levels of reasoning and achievement on standard content are also discussed. (Author/MP)
