“…The questionnaire consists of one major factor ("Core teaching skills", ten items, e.g., "Session is well structured") and two minor factors ("Student activation skills", two items, e.g., "Teacher asks questions to check student learning outcome"; "Student workload", two items, e.g., "Teaching pitched to the student level"). A five-point Likert scale was used for responses: "strongly disagree" (1), "disagree" (2), "neither agree nor disagree" (3), "agree" (4), and "strongly agree" (5). Cronbach's alpha coefficients as a measure of internal consistency of the three subscales were sufficient for two of the three subscales: α = 0.723 ("Student workload") and α = 0.816 ("Core teaching skills").…”
