Describes five college and two high school students' understandings of function and limit in a graphics calculator-based environment and identifies instances where students' understanding seems to have been influenced by the availability of a graphing calculator. (27 references) (MKR)

The difficulties and misconceptions that many students experience when learning to visualize graphs of functions are discussed. Specifically, the inability to make accurate connections between symbolic and graphical representations, the lack of understanding about scale and scaling, and the confusion caused by transformations are examined with…

A tissue culture experiment that does not require elaborate equipment and that can be used to teach sterile technique, the principles of animal cell line maintenance, and the concept of cell growth curves is described. The differences between cancerous and normal cells can be highlighted. The procedure is included. (KR)

Discusses a classroom presentation using a Tonka toy truck's forward and backward motion that (1) develops a graphical representation of the truck's one-dimensional motion; (2) creates graphs representing constant velocity; (3) leads students to a definition of average velocity; and (4) introduces the concept of instantaneous velocity. (MDH)

Describes a library-based instructional module for first-year athletes as part of a program motivated by accreditation agencies, public concern, and NCAA (National Collegiate Athletic Association) standards to ensure the academic success of college athletes. The development and implementation of the bibliographic instruction sessions are…

One implication of attitude self-ratings, that scales may become recalibrated transiently, was investigated conservatively using hypothesized shifts of data from 368 college students rating the desirability of taking senior comprehensive examinations. Results support the validity and reliability of simple graphic rating scales as measures of…

Explores algebraic thinking as children search for patterns while collecting, organizing, and graphing data and as they derive equations describing relationships found in the data. (ASK)

Describes the development of an Interactive Teaching and Learning Environment for Graph Sketching (ITALEGS) of polynomial graphs at the college level. Highlights include hypermedia examples, the design of questionnaires for evaluation, and enhancing effectiveness by incorporating pedagogical content knowledge in computer-assisted instruction.…
