(N)Olympia in Germany? An analysis of the referendum against Munich 2022

In November 2013, local citizens of Munich and the surrounding districts voted in a referendum against a city’s bid for the 2022 Winter Olympic Games. Since this is but one example of such a failed referendum—others being the ones in Poland, Switzerland and Austria—it is astonishing that it seems to become common practice to conduct public polls regarding the bid for a mega sport event. The city of Hamburg, for instance, will be the next German city to hold a referendum on its bid for the 2024 Olympic Games in November 2015. Against this backdrop, we introduce the ‘Arenatheoretical Model’ into mega event research and conduct a qualitative content analysis of the media coverage on the Munich referendum. Three nationwide German newspapers were analysed as the model suggests that this coverage has a profound influence on the public opinion in other parts of the country. The aim was to identify arguments brought forward to explain the outcome of the referendum. Besides a number of other issues, such as concerns regarding event legacy and regional matters, major findings stress the significance of a damaged brand image of international sport organisations and ‘their’ events. Based on these insights, a number of implications can be derived for other cities/nations and sport organisations that depend on a favourable public opinion in their efforts to stage a mega sport event.     

Task-dependent construction of mental models as a basis for conceptual change

Learning can be seen as a task-oriented process which often requires the reorganization of existing knowledge, usually referred to as conceptual change. This paper describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations — propositional symbolic structures and analog mental models. According to this view, conceptual change is based on a task-oriented interaction between these different kinds of mental representations. The assumption is made that it is possible to foster conceptual change by presenting to students well-defined tasks that stimulate the construction of elaborated mental models as well as an intensive interaction between these models and the corresponding propositional representations. In order to test this assumption an empirical study was conducted, in which subjects had to express their prior knowledge about a complex subject matter from the field of geography (time differences on the earth), which contained various conceptual deficits. The subjects were then randomly assigned to different groups who received the same learning material but had to solve different learning tasks requiring differently structured mental models. Afterwards, the subjects were asked to express their knowledge about the subject matter again and were tested for understanding with a comprehension test. The results support the view that a task-oriented interaction between propositional structures and mental models can help learners to evaluate the consistency of their conceptual knowledge. Accordingly, conceptual deficits result in the formation of mental models with an inadequate structure. Such deficits can be detected if the respective model is used in a sufficiently variable way, whereas they can remain unnoticed if it is used in a limited manner.     

A new instrument for measuring pre-service biology teachers' pedagogical content knowledge: The PCK-IBI

Teachers' pedagogical content knowledge (PCK) is highly important for effective design and implementation of school teaching. Thus, the current status, development and efficacy of this knowledge, its relationships with teaching quality parameters, and its impact on students' learning processes and success, require rigorous examination. Thoroughly validated, objective and reliable test instruments that are highly sensitive to changes in variables of proven knowledge-related relevance in teacher education are also required. Previous attempts to design such instruments for assessing science teachers' PCK have largely focused on mathematical content. Therefore, here we present an instrument (the pedagogical content knowledge in biology inventory, PCK-IBI), based on conceptualizations of teachers' professional competence, for assessing secondary school pre-service biology teachers' PCK. In a series of three evaluations and refinements it was tested with samples of N = 274 and N = 432 German pre-service as well as one sample of n = 65 German pre-service and n = 35 German in-service biology teachers. Item analysis, scale analysis and empirically obtained indicators of validity suggest that the final 34-item-version of the PCK-IBI is unidimensional, provides objective test scores and enables reliable and valid registration of pre-service biology teachers' PCK. Thus, hypotheses regarding specific aspects of the model on which the PCK-IBI's construction is based on are empirically supported. The results of our study provide empirical support for the instrument's potential utility.

Summary Development in Kindergarten and Primary School The article considers some general societal structural developments in the areas of kindergarten and primary school (number of students in the classroom, maternal employment, single parenting, school autonomy). It also discusses the possible effects of these developments on future changes in the areas of kindergarten and primary school, as well as the integration of these two sectors.
