i. Teaching and learning activities
The teaching methods to be used are divided into three broad categories – mass-instruction methods, student-centered learning methods based on individualized study, and group-learning methods.
\u2022 Mass-instruction techniques: including but not limited to lectures and similar expository techniques like seminars and workshops; and mass practical work;
\u2022 Individualized-learning techniques: including directed study of material in textbooks, paper-based self-study materials, self-instruction via mediated materials, computer-based learning and multimedia, individual assignments, projects, and individual practical work;
\u2022 Group-learning techniques: including buzz sessions and similar small-group activities; class discussions, seminars, group tutorials; participative exercises of the game\/simulation\/case study type; mediated feedback\/discussion sessions; group projects and self-help groups.
ii. Assessment Methods
Formative and summative assessments for learners shall be used.
\u2022 Assignments, Seminar presentations, Seminar reports, Practical reports, Practical tests, Quizzes, Theory tests, University Exam<\/p>\n
