Bachelor of education (B.ED) Arts (Computer Studies / Business Studies) is not very common for those universities that offer this combination or diploma institutions of the same.
If you have this combination or are pursuing the same, there is no need of panic. However there is one loop hole that you did not consider before enrolling for this course.
It is disgusting to learn that many public universities do not offer computer with any other combinations in their institutions which is common to private universities such as Mt. Kenya, Catholic and Gretsa. Maybe that is the reason why computer studies is limited with teachers across the country.
But why is Computer/Business a disadvantageous combination?
This problem appears when students select subjects in form 2. In most schools, Computer studies is paired with Agriculture, Home Science, Business Studies, or any other group 4 and group 5 subjects. When these subjects are paired, it means that they are taught at the same time (this disqualifies the computer teacher from teaching business form 3 and 4 class unless there is another teacher they can share with).
Consider this statistics:
So before you pursue this combination, you should know that your are 50%-85% disadvantaged to get hired as compared to Computer/Mathematics and Computer /Physics combinations. But you must also have Mathematics and Business a C+ or better. Good luck!
