Adding illustrations to texts might improve students' science achievement. This meta-analysis of 121 effect sizes from 63 studies of 7,621 students across five decades determines both the overall effect and moderators that account for differences across studies. Our random-effects model shows a positive effect of adding illustrations to texts on…

We describe and evaluate a method to mitigate unwanted student collaborations in assessments, which we recently implemented in a second-year undergraduate mathematics module. The method requires a list of specific pairs of students to be prevented from collaborating, which we constructed based on the results of previous assessments. We converted…

This empirical research study investigates the relationship between the utilization of Universal Design (UD) elements and math performance among eighth graders. We analyzed 2017 National Assessment of Educational Progress process data using Poisson Generalized Linear Mixed-Effects Models to examine how the frequency of UD element usage varies…

In this experimental study, 44 undergraduates completed five computer-based instructional lessons and either two multiplechoice tests or two fill-in-the-blank tests. Color-coded borders were displayed during the lesson, adjacent to the screen text and illustrations. In the experimental condition, corresponding border colors were shown at posttest.…

A study involving 25 students (grades 3-5) with and without attentional deficits assessed generality to a standardized reading test when noninformational color was added to one of two alternate forms. Students with attentional deficits read as accurately as their classmates with color added and read worse in the black-white condition. (Contains…

The effect of verbal and visual (color or black/white) coding strategies in self-paced instruction and test materials in facilitating student retention on different cognitive tasks was studied. The 176 college student subjects received instruction and testing using varied combinations of color or black/white materials. Instructional materials were…

This investigation considers the instructional effects of color as an over-arching context variable when learning from computer displays. The purpose of this investigation is to examine the posttest retrieval effects of color as a local, extra-item non-verbal lesson context variable for constructed-response versus multiple-choice posttest…

The purpose of this study was to examine the effect that coding (black and white, and color) and testing mode (visual/verbal) has on the achievement of students categorized as field independent (FID)/field dependent (FD) learners. One hundred eighty-three students enrolled in basic college level educational psychology courses were classified as…

The purpose of several studies was to examine the effects that differentially coded (black and white or color) illustrations had on students who were classified as field independent, field neutral, and field dependent on tests measuring different educational objectives. The effects of visual and verbal test formats were also examined. In general,…

Argues that external cues provide affective information that influence processing strategy and, therefore, examination performance. Notes the differences in performance for two midterm examinations, identical, except that they were printed on blue and red paper. Discusses a method for appropriately adjusting scores to control for form effects.…
