COMPUTER STUDIES SCHEME OF WORK FOR SS3

Computer studies as a school taught subject goes beyond learning how to use the computer and programming. Computer studies is the study of ways of representing objects and processes. It involves identifying, analysing, and designing solutions to problems faced by individuals and the entire society. The importance of this subject can not be over emphasized. Below is the scheme of work containing the concepts which learners at the senior secondary three level are expected to learn from the subject. This should also help parents to guide their wards to learn as they stay home for the pandemic.
