An approach to differentiation is illustrated. (DT)

Results from a large-scale study of sixth-form and college students' understanding of elementary calculus and mathematical ideas underlying calculus are presented. Difficulties with speed, tables, linear graphs, curves and differences, the tangent as the limit, and the average rate of change are each discussed. (MNS)

This study, based on individual interviews with 100 students (aged 16 to 22 years), was designed to investigate understanding of elementary calculus (particularly integration and differentiation). Results indicated that items related to understanding integration as the limit of a sum were difficult even for good students. (Author/MP)

Investigated students' (N=110) understanding of elementary calculus using clinical interview method. Analysis of responses to tasks concerning differentiation and rate of change led to detailed data concerning degree of understanding attained and common errors/misconceptions. Implications for mathematics instruction are discussed. (This is a…
