Dynamik individueller Anpassungsprozesse     

Dr. Katja Ferger 《Sportwissenschaft》2010,40(1):9-18

Sports science is predominantly understood as a theory aimed at practical application where sports performance and how it is influenced by sports training are central. The primary task of sports science is to develop technological regulations and prepare background knowledge for solving application problems in sports training. If one considers a theoretically reasoned training plan from this perspective, it is hardly possible according to the theory of sports science as it stands (Selujanov, 1999). The criticism expressed again and again is primarily orientated towards insufficient explanations and reasons for the selection of a certain training programme or the lack of reasons for selected load intensity and load duration as well as insufficient explanation for the athlete’s performance resulting from it. That means it is not possible to make exact statements about the impact of training over time, the right time for introducing it and the duration of its effect on performance. In the same way the identification of individual process models for training adaptations, i.e. combining training measures and individual performance development, are is an important research goal, both in terms of the theoretical and also the practical aspect of training (Tschiene, 1996; Tschiene, 1997). To be able to answer these questions, there are various ways of proceeding. With the goal of researching in detail basic phenomena of adjustment or effect of change in training adjustment, research in the last few years has been orientated increasingly towards time series analytical processes and antagonistic models. These processes are in a position to present or simulate the performance development of the individual as well as changes in the training. Both time series analytical processes and also antagonistic models (e. g. Performance-Potential-Model; PerPot), by an exact simulation of an individual’s training progress, allow for a prognosis of his performance development. For this both processes need differing inputs which quantify both daily training and also daily performance. The goal of this study is to represent the delayed dynamics of an individual adjustment process through time series analytical processes as well as at the same time to configure it through the PerPot-Model. This approach enables a static validation of the individual effect of the training and allows, in contrast to the classic pre-post measurements, an analysis of the intra-individual relationships and structures or more accurate analyses of the impact of training over time, the right time for introducing it and the duration of its effect on performance (Schmitz, 1989). Moreover, as part of the analysis of the present training and performance data, the prognostic quality of the process is tested and the currently differing parameters for judging the quality of the models and the prognoses associated with them are presented and discussed.  相似文献   

Between school and working life: Vocational teachers’ agency in boundary-crossing settings     

Katja Vähäsantanen  Jaana Saarinen  Anneli Eteläpelto 《International Journal of Educational Research》2009,48(6):395-404

This paper investigates agency among vocational teachers with reference to boundary-crossing between school and working life. Our study utilised interviews with sixteen Finnish vocational teachers. Adopting a narrative analysis approach, we found that the teachers had a variety of forms of exercising agency in terms of decisions deliberately taken, and the discourse and actions following these decisions. These forms were: (i) restricted agency, (ii) extensive agency, (iii) multifaceted balancing agency, (iv) situationally diverse agency, and (v) relationally emergent agency. The exercising of agency was intertwined with the main resources and constraints emerging from the teachers’ sense of their professional self, their awareness of their relationships to workplace personnel, and their views of the professional tasks determined by the school. Depending on its nature and direction, agency appears to create diverse conditions for teachers’ productive work in boundary-crossing settings, for developing education and for remaking the work practices of workplaces.  相似文献   

When ethnic minority students are judged as more suitable for the highest school track: a shifting standards experiment     

Nishen  Anna K.  Corcoran  Katja  Holder  Katharina  Kessels  Ursula 《European Journal of Psychology of Education - EJPE》2023,38(1):367-387

When students are grouped into school tracks, this has lasting consequences for their learning and later careers. In Germany to date, some groups of students (boys, ethnic minority students) are underrepresented in the highest track. Stereotypes about these groups exist that entail negative expectations about their suitability for the highest track. Based on the shifting standards model, the present research examines if and how stereotypes influence tracking recommendations. According to this theory, members of negatively stereotyped groups will be judged more leniently or more strictly depending on the framing of the judgment situation (by inducing minimum or confirmatory standards). N = 280 teacher students participated in a vignette study in which they had to choose the amount of positive evidence for suitability they wanted to see before deciding to recommend a fictitious student to the highest track. A 2 (judgment standard: minimum vs. confirmatory) × 2 (target student’s gender: male vs. female) × 2 (target student’s ethnicity: no migration background vs. Turkish migration background) between-subjects design was used. No effects of target gender occurred, but the expected interaction of target’s ethnicity and judgment standard emerged. In the minimum standard condition, less evidence was required for the ethnic minority student to be recommended for the highest track compared to the majority student. In the confirmatory standards condition, however, participants tended to require less evidence for the ethnic majority student. Our experiment underlines the importance of the framing of the recommendation situation, resulting in a more lenient or stricter assessment of negatively stereotyped groups.

Effects of animation's speed of presentation on perceptual processing and learning     

Katja Meyer  Thorsten Rasch  Wolfgang Schnotz 《Learning and Instruction》2010,20(2):136-145

Animations presented at different speed are assumed to differentially interact with learners’ perception and cognition due to the constraints imposed by learners’ limited sensitivity to incoming dynamic information. To investigate the effects of high and low presentation speed of animation, two studies were conducted. In Study 1, participants were 55 students who learned about the functioning of a four-stroke engine from an animation with user-controlled presentation speed. In Study 2, eye movements of 19 students were analysed for different system-controlled presentation speeds of animation. Results indicated that high presentation speeds accentuated global events (i.e., macro-events), whereas low speeds accentuated local events (i.e., micro-events). However, eye movements were primarily affected by the content rather than the presentation speed of animation.  相似文献   

Educating Students in Real-world Sustainability Research: Vision and Implementation   总被引：2，自引：0，他引：2  

Katja Brundiers  Arnim Wiek 《Innovative Higher Education》2011,36(2):107-124

Readers are invited to imagine students helping to solve real-world sustainability problems brought to them by societal stakeholders and simultaneously learning about and contributing to sustainable changes in society. Effective sustainability research education engages students in just that. Higher education institutions are implementing this vision of education in entire curricula, individual courses, and extracurricular research activities. In this article, we build on the literature to describe a vision of sustainability research education and present an evaluative scheme for measuring its effectiveness. We apply the scheme to two sustainability research-education projects in Switzerland to test its applicability and to identify achievements of the projects and the areas where improvement is needed. Areas for improvement include collaboration between academics and practitioners, joint problem definition, and the guidance of students to participate successfully in collaborative, real-world projects.  相似文献   

Long waves in the geography of innovation: The rise and decline of regional clusters of creativity over time     

Malte Doehne  Katja Rost 《Research Policy》2021,50(9):104298

We explain the rise and decline of regional clusters of creativity over time. We argue that this dynamic is the result of the interplay of individually rational decision-making processes with collective externalities of unplanned social encounters; migration to particular places at particular times interacts with a preference to engage with similar others. This interplay leads to the rise and subsequent decline of opportunities for encounters between people who operate in different domains, a basic requirement for radical innovative change. The consequent decline of formerly innovative regions creates opportunities for new innovative regions to emerge. We test this theory using three independently curated datasets. The first includes the geocoded places and years of the births and deaths of 124,860 notable individuals who lived in Europe between 1000 and 1900 CE, used to measure opportunities for domain-diverse encounters in regions and regions’ time-varying attractiveness in global mobility networks. The second and third datasets consist of the geocoded locations and founding years of 3,165 Catholic monasteries and of 16,596 publishing houses. We use these organizational innovations as robust, independent indicators for a region's capacity to foster incremental and radical change. Our paper aims to open a broader social network perspective on the rise and decline of regional clusters of creativity over time.  相似文献   

Truly included? A literature study focusing on the social dimension of inclusion in education     

Goele Bossaert  Hilde Colpin  Sip Jan Pijl  Katja Petry 《International Journal of Inclusive Education》2013,17(1):60-79

Social participation of students with special educational needs (SEN) is a key issue in the inclusion debate. However, the meaning of concepts like social integration, social inclusion and social participation used in current literature is often unclear. Recently, these concepts were clarified based on preschool and primary school literature. The current study assesses the meaning of these concepts for secondary school samples and possible differences with preschool and primary school. A literature review on secondary school literature, including 19 articles, revealed large parallels, i.e. the three concepts can be used as synonyms and include the same key themes: relationships, interactions, perception of the pupil with SEN and acceptance by classmates. Although the subthemes within the key themes largely concurred, one subtheme (i.e. self-perception of social interaction) was added and three subthemes, mentioned in the scheme based on preschool and primary school, were not found.  相似文献   

Not Read,but Nevertheless Solved? Three Experiments on PIRLS Multiple Choice Reading Comprehension Test Items     

Jörn R. Sparfeldt  Rumena Kimmel  Lena Löwenkamp  Antje Steingräber  Detlef H. Rost 《Educational Assessment》2013,18(4):214-232

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N ₁ = 230, N ₂ = 340, N ₃ = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance.  相似文献   

Functioning and participation problems of students with ASD in higher education: which reasonable accommodations are effective?     

Dorien Jansen  Katja Petry  Eva Ceulemans  Ilse Noens  Dieter Baeyens 《欧洲特需教育杂志》2017,32(1):71-88

Abstract

Students with autism spectrum disorder (ASD) experience various functioning and participation problems in higher education, which may cause difficulties such as drop out or low grade point averages. However, it remains unclear how often and during which teaching and evaluation methods the functioning and participation problems occur and which reasonable accommodations are effective in dealing with them. These gaps in the literature are addressed in this survey-based study. In total, 43 students with ASD, 30 student counsellors and 43 students without a disability of institutions of higher education in Flanders (Belgium) participated in the study. The results show that students with ASD most frequently experience problems with verbal and non-verbal communication, are oversensitive to change and have difficulty distinguishing the gist of the syllabus from the details. Furthermore, it is shown that, on average, these problems arise mostly during classical teaching and evaluation methods. Finally, the perceived effectiveness of reasonable accommodations is dependent on the functioning and participation problem experienced by the student with ASD in higher education. In conclusion, both personal and environmental characteristics should be taken into account when selecting and implementing reasonable accommodations for these students.  相似文献   

Online Teacher Training in a Context of Forced Immobility: The Case of Gaza,Palestine     

Giovanna Fassetta  Maria Grazia Imperiale  Katja Frimberger  Mariam Attia  Nazmi Al-Masri 《欧洲教育》2017,49(2-3):133-150

This article discusses an action research study that involved the design and delivery of an online training course for teachers of Arabic to speakers of other languages in the Gaza Strip (Palestine). Grounded in Freirean pedagogy, the course aimed to respond to the employment needs of university graduates by creating opportunities for online language teaching. The action research study explored the dynamics at play within the online educational environment, to evidence elements that challenged and/or facilitated effective collaboration between trainers and trainees. This article retraces and discusses the processes through which the course moved from didacticism to engaged critical pedagogy.  相似文献
