Introduction to Computer (335)
- What do we want to train children for?
Children are to be Trained to use computers in whatever career they opt for. The aim of the course is not lo train students to pursue a career in computers. Some students, of course will opt for computers as a career; for such students, a firm foundation is sought to be laid. - What is the relation of the computer syllabus with other school subjects ?
Computer syllabus should tightly linked with syllabus in other subjects, so that students gain better understanding of computers and of standard school subjects. Many school subjects involve a large number of calculations, of a tedious nature. Such calculations can be done better using a computer. Again, visualizing some of the quantities calculated' through graphs will aid In understanding. - Who will teach the syllabus?
Teachers who teach other subjects will teach computers. Since some of the topics to be taught (e.g. calculus, commercial applications) are highly technical, it will not be possible for a computer teacher to teach them. However, the software that is to be used is quite easy to use and subject teachers should find it relatively easy to teach the syllabus. - How do we train teachers?
In contrast to Secondary syllabus, different teachers may have to be.trained in teaching different modules. It may not be possible for one teacher, e.g., a maths teacher, to teach all the modules. - What do we do about migration?
Every section in the syllabus will, contain a brief recap of skills necessary to understand the new topics. However, schools will have to arrange for training in using 'Windows 95/98 separately, through a bridge.
