Two approaches are discussed for calculating the work necessary to pump water from a conical or parabolic container. The direct method derived from the definition of work is easy to misuse, as illustrated by a student's incorrect solution. (JP)

Results of a study investigating the problem Do students give unbiased evaluations of their mathematics teachers'' showed the correlation between student achievement and evaluation ratings made by students in 16 sections of a calculus course at Ohio State was not statistically significant. (DT)

Details are given of the background and organization of the Curriculum Revision and Instruction in Mathematics at the Elementary Level (CRIMEL) program for undergraduates at The Ohio State University. The first three years of the program are discussed; administrative problems in grouping students for instruction, attempts to use multimedia methods…

The calculator is used to solve certain formidable equations, which arise naturally and which may be difficult or impossible to solve by standard methods, by a method of successive approximations. (MP)

The purpose of this study was to determine whether students' responses to the Ullman student evaluation of teaching, the Student Evaluation of Teaching (SET) instrument, were biased by their achievement. The instrument was administered to all 325 students taking a second course in calculus with economic applications, near the end of the course;…

At the Ohio State University a precalculus course with a very large enrollment was individualized by using a combination of televised lectures, small recitation sections, flexible testing procedures, variable course credit, and other innovative procedures. (SD)

A hand-held calculator is used to explore several easy and interesting mathematical topics involving compound and continuous interest suitable for beginning college students. (MN)

A method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability is given. (MN)

Discusses the use of graphing calculators for polar and parametric equations. Presents eight lines of the program for the graph of a parametric equation and 11 lines of the program for a graph of a polar equation. Illustrates the application of the programs for planetary motion and free-fall motion. (YP)

The rule of 78 is used by banks and loan companies to compute the amounts due when installment loans are paid early. Describes an unexpected case of negative amortization when the rule is applied. Presents an actual problem and discusses the case. (YP)

Argues that the college preparatory curriculum should include more than three years of mathematics. Presents data indicating that 86 percent of students with less than three years of college preparatory mathematics take remedial mathematics and relatively few students are ready to take calculus when they enter the university. (PK)

Argues that while microcomputer and graphing calculators have evolved to a stage where they should be used routinely by mathematics students at all levels, there is sometimes potential to mislead students with computer generated graphs. Examples are included. (PK)
