Secondly, the results of interviews and the open-ended questionnaires were collected and analyzed through keyword method to get items which were then subjected to evaluation. After discussion with some experienced secondary teachers, the researchers organized the items by combining repeated items, separating items with double or triple meanings, sorting out items with re-appearance, and finally reached a preliminary investigation scale of secondary school teachers’ contextual performance with a total number of 37 items. Likert five-point scoring method was adopted in this scale, from “totally disagree” to “totally agree”.
