Mode of instruction
8 2-hour lectures,8 compulsory 1-hour computer practicals and 8 compulsory 2-hour work group sessions
During the lectures at the start of the week the most important concepts are introduced and clarified. The ciontent of the lectures are included in the examination materials. Students re expected to prepare for the lectures by studying the relevant components of the textbook and workbook. The lectures contribute primarily to course objectives A and B.
In the computer practicals, students practise psychometric data analysis in the form of assignments from the workbook. Comparable assignments are part of the Practical Skills Test. Students are required to bring a USB stick to the practicals (as was also customary in the M&S courses of the first year). The practicals contribute primarily to course objective C. Students are expected to prepare for the work group sessions by completing a number of assignments from the workbook which they hand in before the work group session. These assignments are discussed in the work group session and are part of the attendance requirement. During the work group sessions students are also given the opportunity to practice with new assignments. In addition students are required to give a minimum of one presentation on the results of the practical during the work group sessions. The work group sessions contribute to all learning objectives.
Assessment method
The final grade is determined by combining the results of the multiple-choice examination (60%) and the Practical Skills Test (40%, only valid in combination with sufficiently active participation in the compulsory practicals and work group sessions).
The Institute of Psychology uses fixed rules for grade calculation and compulsory attendance. It also follows the policy of the Faculty of Social and Behavioural Sciences to systematically check student papers for plagiarism with the help of software. Disciplinary measures will be taken when fraud is detected. Students are expected to be familiar with and understand the implications of these three policies.
