Group assessments: Dilemmas facing lecturers in multicultural tertiary classrooms'Group is good, and group is good for curing all social ills' was the cynical observation of one of the lecturers in this study. Her comment reflects the uneasiness of lecturers at tertiary institutions with the notion that the educational advantages of group assessments far outweigh the disadvantages and that such an approach promotes the integration of minority groups in multicultural universities. In this article, we reflect on the dilemmas facing lecturers in multicultural tertiary classrooms when they adopt group assessment as a means of evaluation and highlight those challenges which often jeopardise the successful implementation of this type of practice.Keywords: group assessments; implementation; lecturers; multicultural; tertiary
BackgroundThere is much research to support the contention that group work, or co-operative learning, is an effective tool for improving academic performance (Johnston & Miles, 2004;Karakowsky & McBey, 2001;Johnson, Johnson & Smith, 1998a, 1998bLejk, Wyvill & Farrow, 1997;Zhining, Johnson & Johnson, 1995). Researchers argue that students are involved in tasks that could not be attempted alone; multiple skills are brought to bear on problems and conflicting views are aired and considered (Young & Henquinet, 2000;McCorkle, Reardon, Alexander, Kling, Harris & Iyer, 1999;Gatfield, 1999). Olivera and Straus (2004, p.455) suggest that working in groups "fosters transfer of learning to individuals" and that this transfer can be attributed mainly to the "cognitive elements of group interaction". While the benefits of group work are clear, there is a need to differentiate between co-operative work and collaborative work, particularly when group assessment is involved. Panitz (1996) contends that lecturers move uneasily between the tenets underpinning co-operative learning and those that support collaborative learning. According to Panitz and Brufee (1995) an important difference between the two approaches appears to be the teacher's authority. In co-operative learning, teachers assume much responsibility. Bruffee (1995, p.16) notes they 'intervene frequently and randomly in the work of the groups'. In the collaborative approach, group governance 'remains as much as possible in the hands of the students' (Bruffee, 1995, p.17). Bruffee argues convincingly that the former approach, while suitable for students at school, is too restrictive for tertiary students and that the lecturer's vigilance in ensuring accountability undercuts one of the principal aims of tertiary education: that of shifting authority from lecturer to student groups. He points out (1995, p.18) that the controls imposed by co-operative learning 'are likely … to frustrate and discourage adolescents and adults by leaving in place, unquestioned, the hierarchical social structure of traditional learning'. Bruffee further asserts that 'self-governed peer relationships' are the advantages to be gained from collaborative learning but concedes tha...
