Computer Assisted Learning

“Computer-assisted learning (CAL) is to convey a vast amount of information in a very short period of time. It is a powerful method of reinforcing concepts and topics first introduced to you through your textbook, and discussion in the classroom. Computer-assisted learning enables you in a powerful way to comprehend complex concepts.”

Self-Paced This unique characteristic enables learners to move as slowly or as quickly as they like. Material included in the program can be reviewed again and again, as many times as the students require, without any consequences or set backs from the program. This also helps eliminate the negative reinforcement of students’ possible lack of mastery of previously taught instructional material.

Characteristics

Self-Directed This describes the ability of

learners to decide what they want to learn, and in what order they want to learn it, based on their unique learning abilities and characteristics, in order to benefit, enhance, and individualize the learning process for students.

Use of Various Senses

Computer assisted Instruction (CAI) uses computers and various forms of technology that allow students to process instructional material using a variety of different senses. The more senses, or learning channels through which information is processed, the easier it is for students to remember and learn that information.

Contd……

Learning Rate- It is found that CAI enhances student learning rate. Student learning rate has proven to be as much as forty percent faster with CAI than with traditional instruction.

Retention of Learning-According to researchers, student scores on initial tests and delayed tests indicate that students instructed using CAI retain more content than if they had been instructed using traditional instruction only.

Attitudes- A lot of the research examining CAI strategies and their effects on student achievement and learning outcomes simultaneously observes how student attitudes are effected by this instructional strategy. This has led many researchers to the consensus that using CAI strategies will lead to more positive student attitudes than conventional instruction.

PURPOSES OF CAI

Locus of Control-Students instructed using CAI strategies have more of an internal sense of self-efficacy and ability to control their own learning.

Attendance- Students had better attendance when instructed using CAI strategies.

Motivation and Time on Task-Studies show that students instructed by the use of CAI strategies have higher rates of time spent on task in class than students instructed using traditional instruction only.

Cooperation and Collaboration-Cooperative and positive social behaviors are greater among students instructed using CAI strategies.

Variety of Media The utilization of technology

and computers by this strategy encourages student learning by providing a constantly stimulating environment and promotes enthusiasm by presenting academic content in a way that is interactive, enjoyable and relatable for students. Students are exposed to different types of media that they otherwise may not have experienced or interacted with.

Contd……

Choose a relevant topic. Decide the cognitive level of the students, aimed by the module i.e

knowledge, understanding, or problem-solving. Decide the computer assisted learning mode to be used. Develop CAL sequence in the forms of frames.

Introductory frame gives directions to the learner. Learning frame presents the matter to the learner. Test frame tests the learners and gives appropriate feedback.

Pre-validate the CAL by sharing them with peers and students and get feedback.

Too easy, rigid, difficult parts need to be revised. Get the written CAL module converted to a computer program. Do post-validation of the CAL program and make corrections if

needed. Release CAL unit for learners to use and learn.

Types of Instructional Software

1. Applications

Definition

A group of applications programs that is designed to automate general-purpose and specific tasks such as word processing, database management, spreadsheet, attendance, accounting, grade reporting, scheduling and others.

Features

acquire knowledge and insight about content and processes.

enhance problem-solving and thinking skills.

enhance students’ technical skills.

enhance student’s personal productivity.


Example

MS Excel

Excel one of the most popular spreadsheet programs that can used to teach management processes and enhance problem-solving and thinking skills in mathematics and science.


2. Drill and PracticeDefinition

Drill and practice software provides exercises in which students work example items one at a time and receive feedback on their correctness.

Features Reinforce instruction by providing the repetition necessary to move

acquired skills and concepts into long-term memory. Capture and retain the attention of students. Save teachers’ time and efforts. Personalize instruction by meeting individual differences among

learners.


ExampleECS Keyboard Enables students to: Play notes on the

keyboard after seeing them written.

Identify played notes by assessing intervals from played/written notes

Playback written notes quickly.


ExampleMaster the Facts Multiplication:This program was created in response to teachers to use in their classrooms to teach multiplication. Students using Master the Facts Multiplication for as little as ten minutes a day to practice multiplication skills may demonstrate marked improvement in multiplication skills on quizzes and tests..


3. Tutorials

Definition

A tutorial exposes the learner to material that is believed not to have been previously taught or learned. A tutorial often includes pre-test, post test and drill and practice activities.

Features

Follow linear programmed instruction or branching design.

Encourage students to interact, control and response to the program.

Guide the learner throughout learning from the beginning (objectives) to the end (evaluation).

Have computer-management capabilities (e.g. data collection).


Example

Auslan Sign Tutorial

This system provides an easy-to-use and interactive tutorial for learning the basics in communicating in the Australian Sign Language (Auslan). 3D model for signing.

3D model shows emotion.

Numbers Mode.

Over 60 sign phrases to learn.

Random Quiz tests.


Example

Food Hygiene

This tutorial is designed to teach students at a school of medicine a complete course on food hygiene which concerns food and the prevention of illness and maintenance of health. Uses well-prepared text supported by pictures, audio and video clips.


4. SimulationsDefinition

A simulation is a computerized model of real or imagined system designed to teach how a system works and allows learners to create their own sequence for using simulation.

Features Involve students into learning process. Compress time or slow down processes. Save money and resources. Make experimentation safe. Make impossible situations possible and controllable. Let student repeat events as many times as they want.


Example

Infinite Physics Simulator

Infinite physics simulator has a large collection of objects useful for optics simulation including mirrors, prisms, lenses and other transparent objects.


ExampleCurvilinearFriendly design, users do not need to get trained to operate these tools. Using buttons, textboxes and slide bars learners can run or stop the experiment and change the parameters of the phenomena.


5. Instructional GamesDefinition

Instructional games are courseware designed to motivate learning by adding game rules to learning activities.

Features Make learning fun and motivating (Edutainment). Motivate learners via the challenge of competition. Engage the learner in a situation where the learner is competing for

a high score. Include elements of adventure and uncertainty. Provide different levels of complexity that match player’s ability.


Example

Save the Math Apples
