My research is about teachers' competence to programming languages. These teachers will come from two universities in a city. I will conduct a survey much like an exam in which the teachers will answer the correct programming language in each item. Instead of comparing the answers from each university, I will compare their answers to an expert in programming language. The expert will answer the same set of questionnaire given to the teachers. The objective is to find out the validity of using an expert as a research method.
