Computer-assisted instruction (CAI) refers to using computers to provide drill-and-practice, tutorials, or simulations to students, while computer-managed instruction (CMI) uses computers to track student progress and provide individualized learning objectives, resources, and assessments. CAI involves direct interaction between students and educational software, and can take forms like drill-and-practice, tutorials, games, simulations, discovery, and problem-solving. CMI allows instructors to manage instruction for individual students and choose objectives and activities based on their needs. Both approaches provide benefits like self-paced learning and immediate feedback but also have limitations like over-reliance on multimedia or lack of infrastructure.

COMPUTER ASSISTED INSTRUCTION
(CAI) AND COMPUTER MANAGED
INSTRUCTION (CMI)

3. Introduction
Computer-based education (CBE) and computer-based instruction
(CBI) are the broadest terms and can refer to virtually any kind of
computer use in educational settings. Computer-assisted
instruction (CAI) Computer Aided Instruction (CAI) is a narrower
term and most often refers to drill-and-practice, tutorial, or
simulation activities. Computer-managed instruction (CMI)
Computer-managed instruction is an instructional strategy whereby
the computer is used to provide learning objectives, learning
resources, record keeping, progress tracking, and assessment of
learner performance. Computer based tools and applications are
used to assist the teacher or school administrator in the
management of the learner and instructional process.
Content
Computer Assisted Instruction (CAI)
A self-learning technique, usually offline/online, involving
interaction of the student with programmed instructional materials.
Computer-assisted instruction (CAI) is an interactive instructional
technique whereby a computer is used to present the instructional
material and monitor the learning that takes place. CAI uses a
combination of text, graphics, sound and video in enhancing the
learning process. The computer has many purposes in the
classroom, and it can be utilized to help a student in all areas of the
curriculum. CAI refers to the use of the computer as a tool to
facilitate and improve instruction. CAI programs use tutorials, drill
and practice, simulation, and problem solving approaches to
present topics, and they test the student's understanding.
Types of Computer Assisted Instruction
1. Drill-and-practice Drill and practice provide opportunities or
students to repeatedly practice the skills that have previously been
presented and that further practice is necessary for mastery.

4. 2. Tutorial Tutorial activity includes both the presentation of
information and its extension into different forms of work, including
drill and practice, games and simulation.
3. Games Game software often creates a contest to achieve the
highest score and either beat others or beat the computer.
4. Simulation Simulation software can provide an approximation of
reality that does not require the expense of real life or its risks.
5. Discovery Discovery approach provides a large database of
information specific to a course or content area and challenges the
learner to analyze, compare, infer and evaluate based on their
explorations of the data.
6. Problem Solving This approach helps children develop specific
problem solving skills and strategies.
Advantages of CAI
• One-to-one interaction
• Great motivator
• Freedom to experiment with different options
• Instantaneous response/immediate feedback to the answers
elicited
• Self pacing - allow students to proceed at their own pace
• Helps teacher can devote more time to individual students
• Privacy helps the shy and slow learner to learns
• Individual attention
• learn more and more rapidly
•Multimedia helps to understand difficult concepts through multi
sensory
approach
• Self directed learning – students can decide when, where, and
what to learn

5. Limitations of CAI
• May feel overwhelmed by the information and resources available
• Over use of multimedia may divert the attention from the content
• Learning becomes too mechanical
• Non availability of good CAI packages
• Lack of infrastructure
Computer managed instruction (CMI)
Computer-managed instruction (CMI) aids the instructor in
instructional management without actually doing the teaching.
Central CMI themes discussed in the literature are
individualization, behavioral objectives, and educational technology.
The main objective of this study was to compare the outcomes of
two teaching strategies: CMI versus the traditional lecture method.
The learning objectives were based on specified theoretical content
from a Health Assessment course for baccalaureate nursing
students. The design of the study was quasi-experimental
incorporating two experimental treatments applied to two groups on
two occasions. Data analysis addresses differences between groups
using CMI and the traditional lecture method.
Benefits and Limitations of CMI
With the flexibility of CMI systems, the instructor can choose
appropriate objectives and activities in the curriculum based on a
specific student’s needs. If it is conducive to the subject, the
student can also decide in which order to meet the objectives. The
sequence of modules is flexible. The student can also study and
progress at his or her own pace as the CMI system is basically
instructor-free.

6. The limitation of this type of system is the need for a central
computer system that would allow the instructor to identify and
control the student’s activities in different locations at different
times. With the expansion of cable modems and DSL, this limitation
is steadily becoming a non-issue, except in remote areas. The
purpose of CMI is to diagnose student learning needs and prescribe
instructional activities appropriate for the needs assessed. This
assessment can come from tests on different levels of instruction
which show where the student is lacking. The instructor can then
choose appropriate objectives, modules, lessons, and courses in the
curriculum for the student to study The student has the option of
proving mastery of the objectives through module tests that can be
taken immediately, or after completing the instructional activities.
The student is also involved in deciding which modules to pursue in
which order. The pace at which to complete the modules is up to
the student since the activities are mostly instructor-free. An
example of a possible CMI system design is the Plato Learning
Management System (PLM) which is shown in the graphic below.
Each student will have a slightly different design as it is geared
toward the individual.
Conclusion
The world has come into a digital era in this new century and
education as an essential motility that influences the development
of the society. It should catch up with the times and make a good
use of digital technology. CAI and CMI as modern education
approaches are playing their more and more important role in
modern education and have proved their high efficiency and great
prospect.
