This monograph is the third in a series of semiannual reports of research related to reading in secondary schools. The first section of the monograph is made up of three research studies on the validation of teaching procedures to facilitate students' comprehension of content area texts, the graph-reading abilities of seventh grade students, and a…

This article investigates two common methods of determining the line of best fit and then expands on the techniques used in these methods to find the line of best fit by graphing, estimating and using a microcomputer. (PK)

This investigation evaluated performance of university students on visual and nonvisual versions of an achievement test. Two experimental designs assessed the effects and interactions between visual and nonvisual instructional modes, order of drawing test (before or after verbal/visual achievement test), and mode of drawing test (verbal cued or…

The physics learning problem that students usually regard equations and other symbols in physics as algebraic exercises rather than representations of real world phenomena is commonly known. This article discusses how the Web-based interactive instructional materials were used to help students connect the symbolic world and the real world. The…

Among teachers of mathematics throughout the world there has recently been manifested a notable increase of interest in all educational work. This interest is due in part to the present general agitation in every educational line, in part to the influence of such related departments as physics, in part to the increased demands of industry, and in…

An approach to teaching multiplication and division with negative numbers that focuses on graphs to illustrate concepts is revealed. The material and problems used are presented with comments on the teaching methods applied with 11-year-olds. (MP)

Describes the results of a teacher's exploration of the effects of using graphing calculators in calculus instruction in sections other than those that are experimental. Two experimental and two traditional sections of Calculus I and II participated in the study. (DDR)

Described is an activity that uses discarded evergreen trees from Christmas. Tree age and growth characteristics are investigated by looking at the number of whorls and rings of the trunks. Extensions and follow-up activities are included. (KR)

Illustrated is the problem of solving equations and some different strategies students might employ when using available technology. Gives illustrations for: exact solutions, approximate solutions, and approximate solutions which are graphically generated. (RT)

Reports on an investigation of a population of dandelions on a school lawn. Describes the objectives, rationale, study area, and the results of the study. Includes tables and graphs that show data collected. (RT)

Presents a model of the tutoring process that takes into account the evolving tutor/student relationship and the subject matter concerns that the tutor is helping the student master. Reports illustrative data from case studies from which the model is derived. (15 references) (MDH)

This article, which is organized around a single, well-known algorithm for root extraction, presents a way of incorporating dynamical systems into the teaching of mathematics. Included are sample exercises using complex numbers and the computer where students have the opportunity to do some analysis on this algorithm. (KR)

Various ways in which computers can be used in the classroom depending on the subject, students' background, and individual teaching style are discussed. A way to evaluate professional software packages for use in the classroom is included. (KR)

When comparing performances across four versions of Computer as Lab Partner curriculum, increases in understanding were found when students predicted outcomes and reconciled results, and students used a heat-flow model of thermodynamics to integrate their experimental results. Argued is that curriculum must explicitly motivate students to…

Recounts a college economics professor's attempts to explain macroeconomic concepts to a blind student. Considers how explanations of economics principles often rely on graphic presentations. Describes experimental tactile adaptation, using graphs made out of sandpaper, yarn, spaghetti, and other materials. Recommends developing prefabricated…
