The design and development of a microcomputer-managed delivery system for individualized instruction in vocational education

The purpose of this study was to develop a microcomputer-managed delivery system for individualized instruction and learning from a sound rationale and theoretical basis. Its design was to be in a multi-occupational program format for vocational education in particular, but also for education in general.

An individualized instruction model was developed based on individualized learning theory. Based on this model, a comprehensive microcomputer-managed instructional system was developed.

The microcomputer-managed delivery system that was developed can manage and deliver individualized instructional modules using three programs written in BASIC language. Each individualized-instructional module is made up of the following parts: (1) terminal performance objective(s) (TPO), (2) a pre-check for each TPO, (3) learning package(s) containing enabling objective(s), instructional resources, and learning activities, and (4) a post-check for each TPO. The three programs which manage and deliver these modules are: (1) the AUTHOR program, (2) the student DELIVERY (user) program, and (3) the instructor RECORD-keeping program. These programs are written in the Microsoft BASIC language (TRS-80 Level III Disk BASIC) and run only on a TRS-80 Model III microcomputer. The modules can be delivered to the students via a video terminal and/or a line printer (hardcopy). The program concept can be adapted easily to other kinds of microcomputers, as can the programs themselves.

A user manual is included in the dissertation as chapter four. All the programs are included in the appendix.

The system was piloted with a group of students to determine its difficulty for use. It was evaluated by a panel of judges to assure the design and theoretical concepts were included in a workable format.

The microcomputer-managed instructional system was found to be functional, capable of storing records for at least 100 students for a quarter using one 5.25 inch double density single sided disk.

Modules were placed in disk storage by use of the SCRIPSIT word processor program, the use of which had to be learned by instructors using the system. Once the modules were on disk, the instruction manual could be followed step by step to acquire proficiency in the system use.
