Computing students must therefore, be equipped with this skill. The need to do this using the most appropriate language is critical. We are not aware that any such language has been identified based on scientific instruments or parameters, except on individual opinion or affiliation. To this end, adopting the enhanced Alexander?s scheme, we identified and defined a set of criteria critical to the selection of the most appropriate programming language for introducing students to Object-Oriented concepts and programming. Furthermore, based on these criteria, we produced a rating showing the appropriateness of selected programming languages to the teaching and learning of OOP.
