The evaluation is conducted based on data collected from 10 teachers and 250 students at the Center for Informatics -Foreign Languages -Skill in the form of questionnaires and interviews. The authors use questionnaires to collect participants' responses to five main categories including Overall Assessments, Aim and Approach, Language Skills and Language Contents, Design and Organization, and Learner Needs.
