Project Title
Intelligent Tutoring System in Support of Mastery Learning
Project Goal
To assess the effectiveness of video presentation embedded in an intelligent tutoring system (called MIS-Tutor) in support of mastery learning.
Type of Technology Used in the Project Computer-based tutoring systems with embedded dynamic visuals in the form of AVI files

Executive Summary of Results

Multimedia education systems are rapidly growing in popularity because it enables us to provide a variety of presentation modes in support of students’ learning. In particular, interactive multimedia systems with dynamic visual presentations, such as animation and film, are becoming popular because they offer potential to provide an enriched learning environment by reducing students’ cognitive load to learn the pertinent materials. In this research, we tested the effectiveness of dynamic visuals embedded in a computer-based tutoring system in support of mastery learning of management systems at the MBA level. The findings indicate that dynamic visuals have a significant effect on the perception of students in enabling them to learn the learning materials better.

Need for the Project

Briefly explain why you believed there was a need for your project and what teaching approach was used to address this need.

Computer-based tutoring (CBT) has been used in diverse learning environments with the objective to enable the learner to self-pace in learning the pertinent learning materials. In such systems, feedback is a critical part of effective learning, and it is expected that active involvement leads to more effective learning than passive involvement. CBT systems are generally based on the stimulus-response-feedback views of learning that are associated with the objectivist model of learning. Thus, CBT can be viewed as enhancing the cognitive information processing of learners by making the learning process more individually tailored. The learner is guided by the CBT system so that he/she reaches the predefined learning materials built into the system. Therefore, CBT systems can be developed for the learning environments with a well-defined structure, pre-defined learning objectives and a possible solution to the learner’s enquiries. Multimedia technology can enrich the learner’s experience by enabling the presentation of the learning materials in different formats. The question raised in this research is whether inclusion of video presentation in a CBT system is useful to the learner.

Use of Technology

Briefly explain how your project used instructional technology in a new or different way.

The focus of this research was on the effectiveness of dynamic visuals (animation and films) on students’ learning, when used in computer-based tutoring systems. To this end, we embedded eighty (80) video clips in the form of AVI files into learning materials of a computer-based tutoring system (called MIS-Tutor) in support of mastery learning of management information systems at university-level course offerings. Previous tests of MIS-Tutor had proved to be effective in improving students’ learning. This project enabled us to test the effect of added advantage of dynamic visuals on student learning processes.

Instructional Design Plan

Describe how the use of technology used supported your teaching approach:

The objective was to assess the effectiveness of dynamic visuals (in the form of videos) in improving students’ mastery learning of subject matter (i.e., management information systems) that was built into the MIS-Tutor.

The MIS-Tutor is a self-paced computer-based tutoring system, designed to fit the needs of each individual student. It provides immediate feedback to the student about the learning materials that he/she needs to study. MIS-Tutor helps students learn the elementary and fundamental issues, thereby freeing faculty to work with them on the more complex aspects of their course. MIS-Tutor enabled me to use class time to discuss case studies and leading-edge state of information systems.

Yes, the findings from this project can be easily understood and incorporated into other computer-based tutoring systems.

Potential to Impact Student Learning

Clearly define how your project improved student learning - include specific examples of how your project:

Application of MIS-Tutor significantly improves students’ mastery learning of the fundamental issues, thereby enabled me to work with them on discovery of the more complex aspects of the course in the form of discussion of case-studies and related journal articles.

MIS-Tutor has a built in procedure to improve retention of learning materials. This is done by assessing whether it is necessary to test and provide learning materials related to a pre-requisite learning lesson that might have been forgotten by the student. In addition, dynamic visuals embedded in the learning materials are perceived by the students to be useful in learning the subject matter.

A primary advantage of computer-based instruction is its ability to provide improved mastery learning performance by means of one-on-one tutoring. The results of my formative evaluation of the MIS-Tutor support this notion.

The methodology used in MIS-Tutor and the findings related to the effectiveness of dynamic visuals on students” learning is general and can be adapted to any text-based mastery-learning environment.

Assessment Plan

Briefly explain the effectiveness of your assessment plan:

  1. Students’ learning performance with and without the embedded dynamic visuals was assessed based on their performance in two tests.
  2. Student perception regarding the usefulness of embedded dynamic visuals was assessed using structured questionnaires that were administered before and after the use of MIS-Tutor.
  1. Students’ learning performance with and without the embedded dynamic visuals was assessed based on their performance in two tests. Each test consisted of 50 multiple-choice questions.
  2. Student perception regarding the usefulness of embedded dynamic visuals was assessed using Likert-type structured questionnaires that were administered before and after use of the MIS-Tutor.

Yes, assessments used in this research were valid and reliable for assessing the stated hypotheses (i.e., the goals of the project). The tests were randomly selected from materials covered in the assigned textbook. The structured questionnaires were assessed for their reliability and validity.
