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…

Creating charts and graphs is all about visual abstraction: the process of representing aspects of data with imagery that can be interpreted by the reader. Children may need help making the link between the "real" and the image. This abstraction can be achieved using symbols, size, colour and position. Where the representation is close to what…

Most people who are attracted to STEM-related fields are drawn not by a desire to take mathematics tests but to create things. The opportunity to create an algebra drawing gives students a sense of ownership and adventure that taps into the same sort of energy that leads a young person to get lost in reading a good book, building with Legos®,…

This article will expand upon the techniques of Criminologist, D. Kim Rossmo, and Social Psychologist, David Canter for determining a serial criminal's base of operations. The basic framework for our investigation is that of Rossmo, but uses a different criterion for analysing the relationship of points within the hunting area defined by the crime…

Graphs are vital components for analyzing data in the experimental analysis of behavior using single subject research methods. This paper extends the previous literature on the construction of single subject graphs by providing instructions for using Microsoft[R] Power Point[TM] and Microsoft[R] PowerPoint for Mac[R], and describes improved…

Discusses the importance of accurate graphic presentation and describes graphs available on "LabQuest" computer software. Highlights include graphing conventions; prerequisites for computer graphing; bar graphs; pie graphs; stacked bar graphs; line graphs; x/y graphs; scatter graphs; box plots; stem and leaf graphs; best fit graphs; and…

Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…

Describes a kinship graph system implemented in the APL computer language, including the way in which information about individuals is entered into the database and the various ways in which the computer can trace and display family relationships. (MBR)

The use of computer graphic techniques with basic student enrollment statistics is examined to promote understanding of changes in student flow as a function of spatial distribution. Basic initial student enrollment data that serve as input into predictive flow models were modeled at Eastern Kentucky University. The following commercially…

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

Discusses the hardware and software necessary to generate charts and graphs to illustrate numeric data using a microcomputer. The manufacturer, price, operating system, memory requirements, and types of graphs they can produce are given for nine graphics software packages and seven inexpensive plotters. (MBR)

Reviews evaluation standards that are used to assess the quality of projected graphical displays, and discusses their use in evaluating graphs created with computer graphing programs. Design standards for projected graphs are explained, and examples of three types of graphs are shown. (four references) (LRW)

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

GrafTalk is a powerful, easy to use, business-oriented graphics package for producing pie, bar, and line-plot graphs. GrafTalk should run on nearly any CP/M-based system that drives a graphics device through serial/parallel output port. Discusses package installation, structure, documentation, and use, plotting scientific data, and comparison with…

Some experiences with a classroom computer graphics facility are recounted to show how such a facility has changed the views of some instructors teaching mathematics at the college level. Teachers are encouraged to search out and seize opportunities to acquire graphics hardware, with the added teaching capabilities promoted. (MP)
