Describes activities designed to teach students about embedded recursion. Topics cover providing intuitions about embedded recursions, predicting embedded recursions, seeing patterns and processes, presenting graphic designs containing embedded copies of themselves, and exploring graphics, numerical, and word examples. Parts I and II are in…

Reviews Apple-II versions of "CyberLogo Turtle" and "Delta Drawing." Focuses on special features, educational value, design quality, written materials, and ease of use, pointing out strengths and weaknesses. Both programs are given high rankings for criteria reviewed. (JN)

An On-Line Modeling System (OLMS) which should be particularly useful to the biomedical community is described which utilizes a process called "overlaying" to simplify loading and executing programs. OLMS has been constructed and implemented as an interpreter; that is, a program that translates and then executes each source statement in…

A manual describes the use of graphic commands in student-computer dialogues. How to construct axes, windows, boxes and various other computer displays is explained, in particular reference to the ARDS 100 and TEKTRONIX 4002 and 4010 computer terminals. Concrete examples of displays are included. The appendix contains an explanation of the use of…

Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Provides Logo activities designed for adults and children to use together. Although activities are designed for Terrapin/Krell Logo, modifications are provided for use with Apple Logo or TI Logo (Texas Instruments). "Bugs" are introduced in one activity to demonstrate how they can lead to unexpected results. (JN)
