CAI

Week 9 :

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.

Typical CAI provides

1. text or multimedia content

2. multiple-choice questions

3. problems

4. immediate feedback

5. notes on incorrect responses

6. summarizes students' performance

7. exercises for practice

8. Worksheets and tests.

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.

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

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

 Process of CAI Designing 

There are seven process of CAI designing:

1. Preparation is preparing before design the lesson.

2. Design Instruction  is thinking for designing the lesson.

3. Flowchart Lesson is describing the process of the program.

4. Create Storyboard  is preparing to present the texts, pictures and media to write on the paper.

5. Program Lesson is changing the storyboard to CAI 

6. Produce Supporting Materials

7. Evaluate and Revise 

Designing screen of the lesson 

There are three component of designing screen of the lesson:

👰 The pixel of screen

          - 640x480 pixel

          - 800x600 pixel

👰 Color of background

          - Use cool color such as, white or light grey for background.

          - Use cool color such as, dark blue or dark green for the normal texts.

          - Use warm color for the texts which want to highlight.

👰 Format of setting screen

          - Menu

          - Contents

          - Pictures
