Result: Learning java : a programmed instruction approach using Applets

A programmed instruction approach to knowledge acquisition is operationalized by student-teacher interactions that involve monitoring and managing the moment-by-moment progress of a learner throughout the process of achieving a criterion of mastery in a knowledge domain. The teacher is generic and may include another person, a structured text, or a computer. When the steps and increments leading to a task's completion and mastery can be enumerated, the process of interaction-based learning lends itself to implementation with computer-based tutoring systems. The present paper describes a computer-based programmed instruction tutoring system that teaches a learner how to write a simple Java computer program. The system is based on a series of Java Applets, which are computer programs that are downloaded from a network server and executed by a client browser such as Netscape®. The use of Java Applets makes the tutoring system available to learners over the World Wide Web. Performance acquisition data are presented to show an individual learner's progression to task completion and mastery using the tutoring system. Survey data are presented to show the subjective responses of a class of students to the use of the tutoring system. The adoption of this computer-based tutoring system is justified as one component within a personalized system of instruction that also includes lectures and collaborative learning experiences.
