*4.3.3 Method*

Before starting classes, two kinds of testing, sound voice and letters, have been planned along with the method of preliminary experiments. The members of teams will be decided for collaborative learning depending on their personality which is measured by sound voice experiment. The observations in class will be recorded on their learning process. The interaction on LMS among members of their team will be also observed and recorded. The other data, for instance, results of performance (high-stake assessments) and reports (low-stake assessments), decision time of YGPI, and so on, will be gathered.
