We performed an empirical study of the perceived quality of scientific graphics produced by beginning R users in two plotting systems: the base graphics package ("base R") and the ggplot2 add-on package. In our experiment, students taking a data science course on the Coursera platform were randomized to complete identical plotting…

This paper aims to measure the effectiveness of the 3DL on Omani students' acquisition of practical abilities and skills. It examines the effectiveness of the 3D-lab in science education and scientific thinking acquisition as part of a national project funded by The Research Council. Four research tools in a Pre-Post Test Control Group Design,…

Introduction: The authors examined a tablet computer application (iPad app) for its effectiveness in helping students studying prealgebra to solve mathematical word problems. Methods: Forty-three visually impaired students (that is, those who are blind or have low vision) completed eight alternating mathematics units presented using their…

The plotting of multivariate data using computer line-printers has become a popular means of quickly representing multidimensional data. While many plotting programs are available, there is a paucity of research regarding the validity and reliability of interpretations made by viewing such graphics. This study explores the validity of four…

This quantitative study compared the instructional effects of two web-based animation strategies against static graphics by high and low prior knowledge participants. One strategy used animation to gain attention; the second to gain attention and provide elaboration. Participants were 111 college student volunteers. Two-way multiple analysis of…

Describes study of home economics students at Ohio State University that investigated whether computer animated graphics that replicate mental images of rotation and dimensional transformation would be useful in the development of spatial skills. Orthographic drawings are described, and results for treatment and control groups are analyzed. (29…

Discussion of computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 references) (LRW)

A study was carried out at Pennsylvania State University to examine the effects of both textual and computer animated orienting activities--i.e., mediators through which new information is presented to the learner--and practice on the application and problem solving skills of elementary school students. It was hypothesized that students provided…

Effectiveness in presenting information of a modified box plot and a multivariate STAR graph was compared with that of tables for a sample audience for evaluation results (133 school superintendents, 123 journalists, 100 school board members, 100 principals, 100 teachers). Individual item analysis offers guidance for designing multivariate…
