Effects of Intentional Teacher Errors on Achievement of College Students in Remedial Mathematics.

Peer reviewed

Williams, Paul D. – Mathematics and Computer Education, 1987

In this study, 35 students in two sections of a second remedial mathematics course for technical majors were given lectures with and without intentional errors. Achievement in the non-error group was higher, but evaluation scores for teachers making errors were higher. (MNS)

How to Illustrate Numerical Accuracy Problems on any Computer.

Peer reviewed

Simon, Stephen D. – Mathematics and Computer Education, 1987

Numerical inaccuracies, which occur in many ordinary computations, can create serious problems and render answers meaningless. Cancellation and accumulation errors are described, and suggestions for experimentation are discussed. (MNS)
