The widespread availability of computational graphics for personal computers has greatly increased the potential for visual display of research data. The correlation between two variables can be represented graphically by using circles to represent the variance associated with each circle, and by letting the overlap between the circles be…

Examines problems surrounding traditional assessment and evaluation in education and suggests ways to broaden the methodology as well as the validity of the assessment process. A study of elementary school students is described that used computer-generated assessment involving graphic feedback with and without text to study motivation and…

Investigated the effects of presentation format (animation, still graphics, text) and the students' prior knowledge on learning a computer-based physics lesson in grades eight and nine. Results of an analysis of covariance indicated that specific presentation formats are not equally effective for the different prior knowledge groups. (Author/LRW)

Describes study of high school students that was designed to determine the relative effectiveness of color, graphics, and animation in computer assisted learning (CAL) of a mathematical rule. Three CAL modes, in color and in black and white, are compared; pretests and posttests are explained; and further research needs are suggested. (13…
