Presented is an interactive Applesoft BASIC program that graphically demonstrates the central limit theorem. It can be used as the basis of a lab to illustrate the main conclusions of the theorem. (MNS)

In order to estimate the classical coefficient of test reliability, parallel measurements are needed. H. Gulliksen's matched random subtests method, which is a graphical method for splitting a test into parallel test halves, has practical relevance because it maximizes the alpha coefficient as a lower bound of the classical test reliability…

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

This overview of the home market for microcomputers and computer software presents a brief history of the development of the microcomputer and its use in the home. Factors which shape the home market are discussed, e.g., desire for improvement of educational skills, presence of children, previous experience with a computer, and decreasing prices.…

Suggests computer graphing as a topic for computer programing. Reviews Apple II computer graphics information and gives suggestions for writing the programs. Presents equations to help place information onto the screen with proper coordinates. (MVL)

A programing approach is described, using numerical methods to draw implicit functions, without solving the relationships explicitly. Several examples are discussed, with programs and printouts included. (MNS)

Programs (using Logo) developed by children to produce multiples, the Fibonacci series, and square numbers are presented, with graphical representations of functions introduced. Another investigation involves drawing a circle using turtle graphics. (MNS)

Discusses a student project visualizing the surface of a function using computer graphics. Describes topics to complete the project, function and its domain, scaling, coordinate axes, projection of the surface, sketching the graph, plotting, changing the viewpoint, and rotating the axes. Provides a BASIC program using the rotation of the axes and…

Examines data concerning computer literacy of incoming freshmen at Bentley College and discusses changes that are emerging in their computer backgrounds. High school computing resources are discussed; programing languages taught are examined; student experiences with computers and programing, drill and practice, games, and software are described;…

This report discusses the methods, techniques, and software applications used in processing the data gathered in a survey of the physical condition and health of students in Guangdong Province, China. The introduction provides background on the survey. Survey grouping, data items, and survey procedures are then described. A discussion of…
