Computer assisted learning advantages and disadvantages
Computer-assisted language learning (CALL). and computer assisted learning in education | free ppt download
1Referred to as CAL
Term often used interchangeably with Computer-
Based Instruction (CBI), Web Based Instruction (WBI),
Computer-based Learning (CBL), Computer-Enriched
Instruction (CEI), and Web Based Training (WBT)
learning (CALL) is succinctly defined
in a seminal work by Levy (1997: p. 1)
as "the search for and study of
applications of the computer in
language teaching and learning".
Definition- Any use of computers to aid
or support the education or training
of people.4The computer can be made to assist
learning in many ways:
▫ Dense storage of data in an organized form, e.g., a large
textbook could be stored in a classified manner on a 13
▫ Quick access to the data-base in milli-seconds.
▫ Logical comparison of the learner's responses with the
stored key and evaluation of the learner's performance.
▫ Instant feedback of evaluation (both formative and

By using computers in instruction,
information can be displayed effectively
which enables students to understand
concepts easily.Traditional Teaching
A single teacher giving lectures to a
group of students who are expected to
use their notes and textbook to prepare
for periodic examinations
The computer can never replace a teacher. It merely complements
a teacher's role. However, in some areas of interaction, it may be
better than a human teacher. e.g.,
▫It never gets bored or irritated
▫ It never makes mistakes on its own
▫ It permits individual attention
▫ It permits the learner to decide his own pace of learning.
▫ A well created lesson uses multi-media to enrich and enhance
Methods Of Delivery
Drill And Practice
Drill and practice is good for fundamental mastery.
It provides repeated exposure to facts or information, often in a
question or game-type format (e.g., use an MCQ bank for practice).
It also fit nicely into a behavioral approach to teaching and learning
since it measured student performance.12
In this mode, a module (lesson)consists of
presentation of the content in a structured way , task-
prescription to elicit learner's response, and instant
feedback and reinforcement to the learner.
This mode, if used well, could result in 90% retention
of the content (compare with 30% retention after the
Students who are absent or who need remediation
can often benefit from using a computerized tutorial,

Combines presentation of material with drill-and-
practice, games, or a simulation to emphasize material
and assist in learning.13
A simulation is a representation or model of a
real event, object, or phenomenon where
learners can see the results of their actions.
It provides a real-life scenario with the
material to be learned being applied as it would
in the real world.
Simulation provides safety of learning
Students are given the power to manipulate
aspects of models or situations. They see the
results of their decisions immediatelyProblem Solving
Problem solving software allows learners to see
the results of their reactions to various events
Learners manipulate variables, and feedback is
provided based on these manipulations
There is a lot of power to using problem solving
applications in the classroom, provided they match
It is sometimes otherwise difficult to provide
feedback based on individual choices students
without the computer.15
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

▫This used to be a big category of
computer use in the schools, but
the emphasis on programming
skills has decreased significantly.
▫Many schools no longer even
offer programming classes, but
instead are teaching students to

The development of high‐tech computer‐assisted learning
programme is labor intensive, requiring appropriate hardware, backup
and frequent upgrading.
In addition, a dedicated information technology staff is necessary to
provide practical advice and maintenance of the software and
Some people may be less inclined to use electronic resources
because of perceived lack of computer literacy.
20Future TrendsWhile research is still ongoing into the effectiveness of CAL for
medical education, this new learning modality is a rising form
of medical teaching.
• The Association of American Medical Colleges (AAMC) has
established MedEdPortal, a peer-reviewed collection of online
• This resource contains a database of learning resources that
include tutorials, virtual patients and case-based learning
among other medical education resources.
Between the conveniences afforded by CAL,
enhancements over current learning modalities and
increased recognition for publishing CAL modules, there
appears to be a bright future for computer-assisted
