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…

Studies evaluating the graphics in science textbooks have recommended that teachers use eye-catching visuals to reinforce student learning objectives. Similarly, the "Next Generation Science Standards" (NGSS Lead States 2013) suggest that science teachers use visuals to teach English Language Learners (ELLs). However, little research has…

Information systems increasingly provide options for visually inspecting data during the process of information discovery and exploration. Little research has dealt so far with user interactions with these systems, and specifically with the effects of characteristics of the displayed data and the user on performance with such systems. The study…

Discusses the computer generated graphs that can present trends not apparent in the usual printouts of employee data. (IRT)

Presented are two computer programs which can be used to minimize the effort and time necessary to graph several individual functions. (TG)

Argues that graphic images and technologies can be of substantial help to social work practitioners for assessment and intervention with children and families. Suggests a range of graphic tools and techniques, including profiles, ecomaps, sequential ecomaps, contingency diagrams, concurrent graphing, and computerized Visual EcoScan. (DR)

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

Identifies conceptions that students have with regard to the construction of graphs representing everyday situations in a computer learning environment using a GRAPHIC plotter, and examines the resistance of alternative conceptions to formal instruction. Following instruction, no significant improvement in students' performance was observed.…

Maintains that teachers and textbook graphics follow the same basic pattern in illustrating changes in demand curves when product prices increase. Asserts that the use of computer graphics will enable teachers to be more precise in their graphic presentation of price elasticity. (CFR)

This monograph is a guide to effective presentation of report data and information from institutional research. The work focuses on several types of presentation: the written report (alternative ways for presenting information, appearance, and the audience); graphic displays or charts (to present words or data in an organized or symbolic fashion;…
