Mode of instruction

The Psychometrics course is taught over eight consecutive weeks. Each course week comprises a lecture, a computer practical, and a work group session. The two-hour lecture is the first component, and it is given at the start of the week. In the lecture, a lecturer introduces the week’s material and clarifies its most important topics. The material presented in the lectures forms part of the examination material. Students are expected to prepare for the lectures by studying the relevant material from the course book. The lectures contribute primarily to course objectives A and B.

The computer practicals and work group sessions take place on other days of the week than the lectures (in some cases even on the following Monday). Attendance is compulsory for both practicals and work group sessions. In the course of the 1-hour computer practicals, students practise data analysis on the basis of assignments. Comparable assignments are also used in the two skills tests. Students are expected to bring a storage medium to the practical (same requirement as for 1st year bachelor’s M&S courses). The computer practicals primarily contribute to course objective C.

Students are expected to prepare for the work group sessions by completing a number of assignments and handing them in prior to the session. The completed assignments are discussed during the two-hour work group sessions. Students are also expected to give a minimum of one presentation in the course of the series of eight work group sessions. To stimulate the students to actively engage with the material, they are offered the opportunity to practise new assignments during the work group sessions. At the end of the week, a short elaboration of the assignments is published on Blackboard. The work group sessions contribute to course objectives A, B and C.
