Can engineering education in South Africa afford to avoid problem-based learning as a didactic approach?

In this article, the authors support problem-based learning (PBL) based on its high level of alignment in addition to providing learners in engineering with an additional opportunity in learning process competencies, as contained within the South African National Critical Cross-field and Developmental Outcomes (COs). Constructive alignment describes a process in which the learning outcomes (LOs) become the objective for designing a curriculum that enables LOs to be achieved through appropriate activities and an assessment process that enables these LOs to be demonstrated. PBL applies problem-solving as a vehicle in achieving LOs. The degree to which a learner manages to achieve a given LO still serves as the authentic criteria for assessment. In addition, PBL provides learners an opportunity in acquiring non-subject-related skills, also referred to as process competencies, soft-skills, transferable skills, or graduate attributes. These skills are required especially for the management of human capital and are considered as crucial for successful practice in the engineering profession. It is therefore questioned why a PBL approach is not implemented by engineering faculties at South African Higher Education Institutions. The successful implementation of PBL, however, depends on a number of non-didactic issues that are highlighted in this paper. It is concluded that very few didactic methods can achieve the quality of learning we provide to engineering learners when using PBL, and therefore, it is proposed that South African Higher Education Institutions should also provide their academic staff with training opportunities in this regard.     

Creativity in Artistic Education: Introducing Artists into Primary Schools

Despite a more prominent role of arts education in the school curriculum, artistic creativity does not occur to a great extent in primary school practice. More opportunities for teachers to strengthen their know‐how in the field of artistic creativity can therefore be considered important. Arts education projects focus on pupils' development of creativity by means of introducing artists with their divergent working methods into primary schools. Beside fostering pupils' creative openness and skills, arts education organisations aim to transfer artistic enthusiasm to teachers in each project. Collaboration with artists can encourage teachers' artistic creative work. New working methods, techniques or ways of experimenting are more likely to be adopted in daily teaching practice when the project duration consists of several years. However, most projects are short‐lived and the means for a long‐term project policy are limited. Consequently, results in the area of sustainable outcomes concerning artistic creative work with teachers are limited. To create a long‐term view, the availability of financial resources is an important condition in order to realise a mentality change towards artistic creativity in education. Finally, continuing debate with several participants about making artistic creative work sustainable remains necessary.     

Student learning experience as indicator of teaching quality

The purpose of the study was to develop an improved teaching evaluation questionnaire based on students’ learning experiences and selected teacher characteristics identified as indicators of teaching quality. Teaching evaluation questionnaires are commonly designed either based on agreed indicators of teaching excellence, students’ suggestions of characteristics of excellence, or dimensions identified from interviews conducted with excellent teachers. In this study, however, students’ evaluation of their own learning experiences in learner centered classes and a hypothesized framework derived from the literature were used to develop the items for the questionnaire. Students attended to courses designed in a learner centered paradigm and evaluated their learning experiences. Based on the hypothesized framework and students’ reflections of their experiences, items were designed and validated at various levels. Exploratory factor analysis resulted in a 24-item Student Evaluation of Learning and Teaching Questionnaire (SELTQ) that comprises four factors: assessment and feedback; course organization and presentation; student self evaluation; and students’ level of engagement. As opposed to the questionnaire widely used in higher education institutions in Ethiopia that focuses on the evaluation of selected teacher characteristics, the new measure enables students to evaluate teaching in terms of their own learning progress.     

The Split-Ballot Multitrait-Multimethod Approach: Implementation and Problems

Saris, Satorra, and Coenders (2004) proposed a new approach to estimate the quality of survey questions, combining the advantages of 2 existing approaches: the multitrait–multimethod (MTMM) and the split-ballot (SB) ones. Implemented in practice, this new approach led to frequent problems of nonconvergence and improper solutions. This article uses Monte Carlo simulations to understand why the SB-MTMM is working well in some cases but not in others. The number of SB groups is a crucial element: The 3-group design is performing better. However, the 2-group design can also perform well: The analyses suggest that the interaction between the absolute values of the correlations between the traits and the relative values of the different correlations between traits plays an important role.     

Teacher research and the aims of education

We report on the development of a course for experienced teachers in the Netherlands, intended to enhance their professionalism by engaging them in doing research based on reflection on the aims of their educational efforts. The course was accompanied by design-based research. The research question was whether and how the course stimulated teachers to connect doing research and taking a reflective stance; the results were used to improve the course, thus creating a cyclical design. Although the course was positively evaluated by the participants, reflection on its results made clear to us that our approach in the combination of learning to do research and reflecting on aims is not enough to make teachers into critical research-minded professionals. A more context-aware view of their learning process is necessary: the institution school limits their possibilities. The implication is that both our course and our research effort have to be critically revised. Instead of looking for causal effects, one should be aware of traces of development that may or may not be caused by the intervention.     

The contested professionalism of teachers meeting radicalising youth in their classrooms

In a diverse and unjust world, teachers experience difficulties to achieve inclusive education. In parts of the western world, including the Netherlands, the very possibility of a combination of ethnic and cultural diversity and common citizenship has come into question. Meanwhile some youngsters are in the process of radicalisation. We illustrate the problem definitions of teachers and teacher trainers with a case study of a professional learning activity in Amsterdam. This is followed by a critical discussion based on a pedagogical view on education.     

Multichannel marketing: An experiment on guiding citizens to the electronic channels

Governments have a variety of channels at their disposal to help them interact with their citizens. Having realized that citizens still prefer the traditional channels, governments are now focusing on ways to lead them to the web. Previously, we have shown that citizens prefer the use of soft instruments, such as communication. Communication instruments are characterized by the transfer of information from government to citizens, for example, by means of mass media or a letter. This study focuses on how a communication instrument—in this case a personal letter—can be used to lead citizens to the digital channel. We also show the effects of the instrument both in terms of channel usage and citizen perceptions. Based on a field experiment, carried out in cooperation with a Dutch national government agency, we show that unobtrusive channel marketing can be effectively used to increase usage of government e-services, without negatively affecting citizens' current level of satisfaction with service delivery.     

Laser separation of isotopes

Laser separation of isotopes was first shown to be scientifically practicable at the start of the 1970s, when the isotopes of nitrogen, chlorine, hydrogen, and many other elements were successfully separated. Its most important applications are for uranium and plutonium enrichment. Enriched uranium is used as fuel for nuclear power stations, while enriched plutonium can be used to design more effective nuclear weapons. Ninety-eight per cent of all enriched uranium is now produced in gaseous diffusion installations, the remaining 2 per cent being produced by gaseous centrifugation. Research into laser separation is being conducted in numerous countries and will lead to the production of enriched plutonium on an industrial scale by the end of this decade.
