The UWI student association published an evaluation of the courses taught during Semester 1 of AY2020/21. Students in each course completed an evaluation in which they rated a number of different aspects of the course on a 5-point scale (1= very bad to 5=excellent)”. Five variables obtained are: Rating – overall rating of the course. CC – rating of teaching skills of the CC. Assessments – quality of assessments given. Knowledge – rating of the instructor’s knowledge of the material. Grade - student’s anticipated grade for the course (1=F to 5=A).
