This mathematics activity for K-3 students has students plant and measure the growth of bulbs. The activity teaches them to measure, collect, and graph data. The article presents a list of materials needed, instructions for creating a chart, and sample discussion questions. (SM)

Investigates pupils' abilities to interpret graphical information using a comparative study involving data-logging, conventional practical work, and a nonpractical equivalent. Concludes that the computer-based approach seemed to be particularly effective for younger and less-abled pupils. (Author/ASK)

Introduces a method for constructing phylogenies using molecular traits and elementary graph theory. Discusses analyzing molecular data and using weighted graphs, minimum-weight spanning trees, and rooted cube phylogenies to display the data. (DDR)

Microanalyzes graph use in lectures drawn from artifacts compiled from videotaping all lectures and seminars in a 13-week ecology course. Focuses on both the text and the gesture-related references made in the reading of a graph in an ecology lecture. Contains 36 references. (DDR)

The symbolic graphic life-line was used with clients (N=50) in short- or long-term group therapy programs. Information expressed through the life-lines helped to integrate the clients' feelings and thoughts in relation to past events, and aided therapists in devising treatment goals. (MKA)

Draws on information in the Modern Language Association database to identify changes through time in registration levels and the percentage of institutions that offer various languages and language clusters and discusses trends within groups that differ by several institutional characteristics.

A trilinear chart for understanding the distribution of achievement levels of students' performance in the National Assessment of Educational Progress (NAEP) is described and its use illustrated with data from the 1992 state NAEP mathematics assessment. Trends for all 44 participating jurisdictions are simultaneously displayed. (SLD)

Discusses how experiments can offer students different points of view on the mathematical concepts presented in class and bring these concepts to life. Presents an experiment that demonstrates the interaction between mathematics and fluid dynamics. (Author/ASK)

A project developed and evaluated an intermediate form of presentation that provides a virtual dynamic tactile display for use with computers that could complement static tactile displays of graphical material. The device is a two-dimensional extension of the tactile mouse and provides contour and slope information to the user. (Contains nine…

Offers instructors a presentation of the IS (investment saving)-LM (liquidity preference-money supply) model, suggesting that a number of benefits emerge if the instructor focuses on what determines the size of both the horizontal and vertical distances between the IS curves and between the LM curves. (CMK)

Describes PC Logo, an instructional tool that can be used for teaching and enhancing a student's knowledge of graphs and geometric concepts. (CCM)

Investigates the advantages of graphical mapping of national research publication and citation profiles from scientific fields in order to provide additional information with respect to research performance. By means of a multi-dimensional scaling techniques national social science profiles from 17 countries and two periods, 1989-1993 and…

Following a pretest, 11 participants who were naive with regard to various algebraic and trigonometric transformations received an introductory lecture regarding the fundamentals of the rectangular coordinate system. Following the lecture, they took part in a computer-interactive matching-to-sample procedure in which they received training on…

This article describes a connection between literature and mathematics through a story-graphing project. (Contains 7 figures.)

This paper presents an assessment tool which can be used during the first weeks of calculus to measure students' visual thinking skills. We have developed and applied this instrument in classes for the last three years, tabulating results and interviewing students on a regular basis. We discuss our findings and provide hints to using the…
