This material is intended as a programmer's reference for the software package contained in the MTS file K033:CKLIB for use with a Computek terminal. It is assumed that the reader is familiar with FORTRAN programing in MTS and is acquainted with the Computek terminal. (MK)

Provided is a review of an educational software program called "Delta Drawing." Included are comments on how the graphics program works, programing features, comparison with LOGO, educational value, and availability. Indicates that as a powerful learning program, it is innovative and imaginative. (JN)

The use of interactive graphics in computer-aided instruction systems is discussed with emphasis placed on two requirements of such a system. The first is the need to provide the teacher with a useful tool with which to design and modify teaching sessions tailored to the individual needs and capabilities of the students. The second is the…

Several student-authored computer programs are presented which do advanced plot routines. They are remarkable in that they are able to plot a function expressed in polar coordinates on a teletype. Some plot routines developed by the Project Solo staff are also presented. They are designed to be used with a Hewlett Packard 7200 A plotter connected…

Discusses various aspects, features, and uses of the Logo programing language. A comparison (in chart format) of several Logo languages is also included, providing comments on the language as well as producer, current price, number of sprites and turtles, computer needed, and whether debugging aids and list operations are included. (JN)

Presents activities and program listings to print ASCII characters, examine the "IF" command (Pascal), change colors of a word on the screen (Atari), and to create a drawing tool for making designs (Logo). Also presents an activity on dummy sorting. (JN)

Discusses activities for counting using FOR/NEXT commands, finding number of letters in words using LOGO, generating random numbers on the TRS-80 (program listing included), and examining mistaken predictions. Includes the article "Animating Graphics in BASIC" by Ellen Joslin (program listing included). (JN)

Discusses a computer program which converts TRS-80 programs into Applesoft Basic. Although the complete program is listed, a disk containing the binary files necessary for the conversions is available (current cost $10.00) from the author. (Author/JN)

The interactive system for creating graphic displays that is described is presented as one solution to the problem created by the lack of complementary firmware or software to make the graphic capabilities of many current terminals easily accessible to the instructional programmer. The use of this system by the Digital Equipment Corporation's…

A general description is provided of the "geometric dictionary," a graphic display aid, used by the Computer-Assisted Instruction Laboratory at the Pennsylvania State University. The purpose of the description is to enable the reader to duplicate and use the dictionary on any cathode ray tube terminal of the IBM 1500 system. The major…

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)

A theory of the planning and debugging of computer programs is formalized as a context free grammar, which is used to reveal the constituent structure of problem solving episodes by parsing protocols in which programs are written, tested, and debugged. This is illustrated by the detailed analysis of an actual session with a beginning student…

The currently operational version of the INGRES data base management system gives a relational view of data, supports two high level, non-procedural data sublanguages, and runs as a collection of user processes on top of a UNIX operating system. The authors stress the design decisions and tradeoffs in relation to (1) structuring the system into…

Presents programming ideas using LOGO, activity for converting flowchart into a computer program, and a Pascal program for generating music using paddles. Includes the article "Helping Computers Adapt to Kids" by Philip Nothnagle; a program for estimating length of lines is included. (JN)

Describes subroutines in a group of assembly-level programs (program listings included) which provide the interface between a Basic, Pascal/Z, or JRT Pascal program and the BASE2/IDS-560 graphics printer. The interface can be easily modified for other printers and other languages. (JN)
