Computer assisted instruction (CAI) refers to the use of computers to facilitate learning through tutorials, drills, simulations, and problem-solving exercises. It allows for one-on-one interaction, immediate feedback, self-pacing of instruction, and helps teachers devote more time to individual students. Computer managed instruction (CMI) uses computers to track student progress, prescribe instructional activities based on assessments, and allow students to prove mastery of objectives at their own pace. CAI and CMI are effective modern educational approaches that make good use of digital technology to improve the efficiency of instruction and are playing an increasingly important role in education.

2. 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,computer aided instruction is a narrower term and most often
refers to drill and practice,tutorial , or simulation activities. Computer
managed instruction (CMI) is an instructional strategy whereby the
computer is used to provide learning objectives,learning resourses,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 learner and instructional
process.

3. Content
Computer assisted instruction
A self learning technique, usually offline /online ,involving
interaction of the student with programmed instructional
materials.Computerassisted instruction (CAI) is an interactive instructional
technique whereby a computeris 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
computerhas 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 computeras
a tool to faciliate and improve instruction.CAI programs use tutorials , drill
and practice,simulation and problem solving appprochesto 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 necessery for mastery.
2.Tutorial
Tutorial activity includes both the presentation of information and its
extention in to different forms of work ,including drill and practice ,games
and simulation.
3.Games
Games 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 expence of real life or its risks.

4. 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 evaluatebased on their explorations of the data.
6. Problem solving
This approach helps children develop specific problem solving skills and
strategies.
Advantages of CAI
1. One –to-one interaction
2. Great motivator
3. Freedom to experiment with different options
4. Instantaneous response/immediate feedback to the answers elicited.
5. Self pacing - allow students to proceed at their on pace
6. Helps teacher can devote more time to individual students.
7. Privacy helps shy and slow learner to learns
8. Individual attention
9. Learn more and more rapidly
10. Multimedia helps to understand difficult concepts through multisensory
approach.
11. Self directed learning –students can decide when,where,and what to
learn.
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
studets’s activities in different locations at different times. With the
expansion of cable modems and DSL ,this limitations steadily becoming a
non-issue, except in remote areas.The purpose of CMI is to diagnose

5. 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(PLM) which is shown in the graphic
below.Each student will have a slightly different design as it is geared
toward the individual.
Conclusion
This world has come in to a digital era in ths new century and
education as an essential motility that influences the developmentof the
society.Itshould catch up with the times and make a good use of digital
technology.CAI and CMI as moderneducationapproaches are playing their
more and more important role in moderneducation and have proved their
high efficiencyand great prospect
