Computer Assisted Instruction
• Referred to as CAI• Terminology – Computer-Based Instruction (CBI), – Web Based Instruction (WBI), – Computer-Assisted Learning (CAL), – Computer-Enriched Instruction (CEI), and – Web Based Training (WBT)

Computer Assisted Instruction
• 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.
![Page 6: Computer Assisted Instruction Archana Presentation](https://reader036.vdocuments.net/reader036/viewer/2022082309/544953e7b1af9f53618b4fed/html5/thumbnails/6.jpg)
Origin of CAI ?
• After the development of a small commercial computer in U.S.A to process census data – around 1960
• Development of PLATO (Programmed Logic for Automatic Teaching Operations) - around 1964
• Development of computerized tutorials in arithmetic and reading for elementary school children by Patrick Suppes of Stanford University in 1966 and in fact he was considered to be the father of CAI.

Drill-and-practice
• The drill and practice technique assumes that the skills that have previously been presented have been given for further practice to gain mastery.
![Page 9: Computer Assisted Instruction Archana Presentation](https://reader036.vdocuments.net/reader036/viewer/2022082309/544953e7b1af9f53618b4fed/html5/thumbnails/9.jpg)
• Opportunity for the learner to practice material an unlimited number of times
• Best method for material that requires repeated practice to master (ex: multiplication tables)
Drill-and-practice

Drill-and-Practice
• Educating farmers about the importance of integrated pest management.
•Educating individuals about the importance of food safety.

Games
• Games use the instructional material to create a contest for the learner
• The learner can compete against his own personal best, the computer, or other learners while mastering the material
![Page 12: Computer Assisted Instruction Archana Presentation](https://reader036.vdocuments.net/reader036/viewer/2022082309/544953e7b1af9f53618b4fed/html5/thumbnails/12.jpg)
Games
• The use of computer games is a valuable resource to reinforce instructional material.
• The teacher can teach the content in a traditional manner and then use CAI to allow the student practice with the information learned.
• Programs tend to resemble a game format which motivates the student and captivates their interest.

In the following game the 1 pops up then the 1 dog pops up in the rectangle. Then the 3 pops up and 3 dogs go into the rectangle.
The voice then talks the student through the math problem.
It then prompts the student with the hand pointing towards the correct answer.

The objects then jumps down to the number line and represent the total
number of objects.

Simulation
• Simulation software is an ingenious resource that can provide an approximation of reality that does not require the expense of real life or its risks.
• Simulation provides safety of learning environment
![Page 17: Computer Assisted Instruction Archana Presentation](https://reader036.vdocuments.net/reader036/viewer/2022082309/544953e7b1af9f53618b4fed/html5/thumbnails/17.jpg)
Simulation
• This technique can be used (and is not limited to) teaching individuals about the importance of emergence preparedness, how to handle disease outbreaks, the effects of bioterrorism and environmental health.

Discovery
• Discovery software usually provides a large database of information specific to a specific content area and challenges the learner to analyze, compare, infer and evaluate based on their explorations of the data.
• Provides the learner with an opportunity to draw his own conclusions
![Page 19: Computer Assisted Instruction Archana Presentation](https://reader036.vdocuments.net/reader036/viewer/2022082309/544953e7b1af9f53618b4fed/html5/thumbnails/19.jpg)
Problem Solving• Problem Solving software
teaches specific problem solving skills and strategies. This technique can be used by presenting multiple health scenarios to participants asking them to solve the problem and providing feedback to them about their health choices.

Tutorial
• Most popular method of Computer Assisted Instruction
• Often combines presentation of information and its extension into drill-and-practice, games, or a simulation to emphasize material and assist in learning.
• E.g.: Use of soil solarization

Pros of Computer Assisted Instruction
One-on-one interaction Freedom to experiment with learning options Immediate Feedback Self-pacing Privacy for shy/slow learners Learners have been found to learn more and more
rapidly Multimedia provides a variety of formats to present
difficult material Self-directed learning allows learners to decide when,
where and what to learn

• Overuse of multimedia can detract from intended learning objectives
• Inability to ask a “person” a question when material is not understood
• Equipment can malfunction• Lack of good CAI packages or lack of
infrastructure to deliver CAI
