Comparing native and non-native teaching techniques in the nuclear power plant english classes

In my thesis I examine the language education system in Hungary's only one Nuclear Power Plant in Paks. This observation was made among adult learners who learn English from a native and a non-native teacher. It is an interesting task to decide if native or nonnative teachers and teaching techniques are better. I made a hypothesis that both the native and the non-native teachers are necessary to learn English. To support that this statement is true I made a research and used questionnaires for the learners and for the teachers, as well. The evaluation of the lesson observation and the questionnaires will support my hypothesis.
