Argumentation in Science Education: A Model-based Framework     

Florian?B?ttcherEmail author  Anke?Meisert 《Science & Education》2011,20(2):103-140

The goal of this article is threefold: First, the theoretical background for a model-based framework of argumentation to describe and evaluate argumentative processes in science education is presented. Based on the general model-based perspective in cognitive science and the philosophy of science, it is proposed to understand arguments as reasons for the appropriateness of a theoretical model which explains a certain phenomenon. Argumentation is considered to be the process of the critical evaluation of such a model if necessary in relation to alternative models. Secondly, some methodological details are exemplified for the use of a model-based analysis in the concrete classroom context. Third, the application of the approach in comparison with other analytical models will be presented to demonstrate the explicatory power and depth of the model-based perspective. Primarily, the framework of Toulmin to structurally analyse arguments is contrasted with the approach presented here. It will be demonstrated how common methodological and theoretical problems in the context of Toulmin’s framework can be overcome through a model-based perspective. Additionally, a second more complex argumentative sequence will also be analysed according to the invented analytical scheme to give a broader impression of its potential in practical use.  相似文献   

Pre-service teachers’ personal epistemic beliefs and the beliefs they assume their pupils to have

In their workaday life, teachers are faced with multiple complex tasks. How they carry out these tasks is also influenced by their epistemic beliefs and the beliefs they assume their pupils hold. In an empirical study, pre-service teachers’ epistemic beliefs and those they assume of their pupils were investigated in the setting of teacher education for vocational schools in Germany. Results of the empirical study point at significant inconsistencies between pre-service teachers’ beliefs, the beliefs they assume of their pupils and beliefs conducive to the curricular and didactic concept preferred for vocational schools. Partly, these inconsistencies can be explained by pre-service teachers’ learning experiences in school and university. It seems important that the education of teachers in vocational education aims at scaffolding pre-service teachers in developing beliefs that are conducive for their future profession.  相似文献

Carbohydrate intake and training efficacy – a randomized cross-over study     

Florian Beaudouin  Frederic Joerg  Anette Hilpert  Tim Meyer  Anne Hecksteden 《Journal of sports sciences》2018,36(8):942-948

Carbohydrate (CHO) availability during endurance exercise seems to attenuate exercise-induced perturbations of cellular homeostasis and might consequently diminish the stimulus for training adaptation. Therefore, a negative effect of CHO intake on endurance training efficacy seems plausible. This study aimed to test the influence of carbohydrate intake on the efficacy of an endurance training program on previously untrained healthy adults. A randomized cross-over trial (8-week wash-out period) was conducted in 23 men and women with two 8-week training periods (with vs. without intake of 50g glucose before each training bout). Training intervention consisted of 4x45 min running/walking sessions/week at 70% of heart rate reserve. Exhaustive, ramp-shaped exercise tests with gas exchange measurements were conducted before and after each training period. Outcome measures were maximum oxygen uptake (VO_2max) and ventilatory anaerobic threshold (VT). VO_2max and VT increased after training regardless of CHO intake (VO_2max: Non-CHO 2.6 ± 3.0 ml*min^?1*kg^?1 p = 0.004; CHO 1.4 ± 2.5 ml*min^?1*kg^?1 p = 0.049; VT: Non-CHO 4.2 ± 4.2 ml*min^?1*kg^?1 p < 0.001; CHO 3.0 ± 4.2 ml*min^?1*kg^?1 p = 0.003). The 95% confidence interval (CI) for the difference between conditions was between +0.1 and +2.1 ml*min^?1*kg^?1 for VO_2max and between ?1.2 and +3.1 for VT. It is concluded that carbohydrate intake could potentially impair the efficacy of an endurance training program.  相似文献

Von der Meritokratie zur Parentokratie?     

Florian Waldow 《Zeitschrift für Erziehungswissenschaft》2014,17(3):43-58

In 1990, the English educational sociologist Phillip Brown argued that the age of meritocracy had been replaced by a mode of allocating life chances following an “ideology of parentocracy”. In a parentocracy, parents’ wishes and resources are decisive for the allocation of life chances of individual pupils. This proposition was taken up many times in the following years. The article argues against the parentocracy proposition and argues that meritocracy has not become weaker as a legitimatory norm of the allocation of life chances and social inequality. However, on the level of the actual operation of the educational system and its interaction with its environment, parentocracy does play a role. This is discussed using on the one hand the way in which Eton College presents itself to its environment and on the other hand how it actually recruits pupils. The article discusses this using a neoinstitutionalist theoretical frame. Finally, the article discusses the ambivalent role of performance data within the uneasy relationship of meritocracy and parentocracy.  相似文献   

Human handedness in interactive situations: Negative perceptual frequency effects can be reversed!     

Jörg Schorer  Florian Loffing  Norbert Hagemann  Joseph Baker 《Journal of sports sciences》2013,31(5):507-513

Abstract

Left-handed performers seem to enjoy an advantage in interactive sports. Researchers suggest this is predominantly due to the relative scarcity of left-handers compared with right-handers. Such negative frequency-dependent advantages are likely to appear in inefficient game-play behaviour against left-handed opponents such as reduced ability to correctly anticipate left-handers' action intentions. We used a pre–post retention design to test whether such negative frequency-dependent perceptual effects can be reversed via effective training. In a video-based test, 30 handball novices anticipated the shot outcome of temporally occluded handball penalties thrown by right- and left-handed players. Between the pre- and post-tests, participants underwent a perceptual training programme to improve prediction accuracy, followed by an unfilled retention test one week later. Participants were divided into two hand-specific training groups (i.e. only right- or left-handed shots were presented during training) and a mixed group (i.e. both right- and left-handed shots were presented). Our results support the negative frequency-dependent advantage hypothesis, as hand-specific perceptual training led to side-specific improvement of anticipation skills. Similarly, findings provide experimental evidence to support the contention that negatively frequency-dependent selection mechanisms contributed to the maintenance of the handedness polymorphism.  相似文献   

The influence of a new sole geometry while running

Abstract

Running shoe construction influences the forces experienced by the human body while running. The aim of this study was to ascertain whether the new sole architecture of the On running shoe reduces ground reaction forces compared with running barefoot or with a conventional running shoe and whether it changes the physiological parameters of running in shoes. Thirty-seven trained male participants were studied while running at submaximal speeds wearing their conventional running shoe, wearing the On running shoe and while barefoot. Additional biomechanical and physiological values were investigated to determine whether the On running shoe induced any changes in these parameters compared with conventional running shoes. The On exhibited similar ground reaction forces as conventional shoes, and these were different from the forces experienced while running barefoot, showing that the On was more similar to typical shoed running. No difference was observed in running economy between the On and a conventional shoe model. However, a slightly lower heart rate (HR) (≈1.3%) and blood lactate concentration (≈5.5%) were observed during submaximal running with the On running shoe compared with a conventional running shoe, as well as a greater lateral deviation of the centre of pressure mid-stance. The ramifications of the reduced HR and blood lactate concentration for competitive performance are unknown.  相似文献
