ABSTRACTOnline education and in particular Massive Open Online Courses (MOOCs) are often regarded as a way to solve global educational challenges. In this article, we highlight the students’ uptake of such a ‘digital solution’. Presenting initial findings from a research project in Germany, we situate our investigation in the specific context of digital educational offers for refugees, using Kiron Open Higher Education as an example. Kiron has designed an innovative academic model, with MOOCs at its core, to ease refugees’ access into higher education. Drawing from student data of 1375 Kiron students we look at students’ actual usage of the offer and the accompanying support services as well as the difficulties refugee students face while navigating online higher education. Results show, amongst others, rather low completion rates in the online courses and point to a much more nuanced picture of how students make use of the offer – putting online education as an easy, straightforward formula to the integration of disadvantaged students into question. 相似文献

Kinetic (3-D force plate), kinematic (videography) and temporal characteristics of backstroke turns by 20 male and 16 female swimmers were recorded to identify and describe key elements of backstroke turning performance. Data were recorded during a 50 m maximum effort swim in a 25 metre pool. A Pearson product moment correlation matrix revealed that the 5 m RTT was significantly correlated with anthropometric measures of height, mass, trochanteric height and age; kinetic measures of horizontal impulse and peak force; and kinematic measures of wall contact time and peak velocity. The stepwise multiple regression equation to predict 5 m RTT was: 19.6-0.75 trochanteric height-1.8 wall exit velocity-0.03 peak vertical force. Four key factors were identified from a principle components factor analysis--anthropometry and force, post-turn velocity, force preparation and rotational skills. Implications from the findings were that age-group backstrokers should 'hit the wall hard' with relatively extended legs to reduce swim distance and push-off deceleration; use minimal wall contact time, and maximise forces to develop high horizontal velocities in a streamlined position. 相似文献
