German orthography is known to be quite difficult to master, especially for primary-school pupils in writing texts [cf. 1]. In order to support children with the acquisition of German orthography, we are developing a web-based platform for German-speaking users based on learning analytics techniques. Our goal is to motivate pupils age 8 to 12 to improve their spelling abilities by writing texts and by the possibility to publish them. Concerning spelling in combination with learning analytics the system provides - in case of an orthographic mistake - a specific feedback that encourages pupils to think about the spelling and to correct it. Based on occurred mistakes the teachers and the students are provided with a qualitative analysis of the mistakes. This analysis shows the problematic orthographic areas and gives suggestions for online and offline exercises as well as online courses that are explaining the orthographic phenomena. The aim of this article is to describe the architecture of the web-based system and a proof of concept by evaluating 60 essays. Furthermore, relevant background information is given in order to gain a better understanding in the complex interdisciplinary development. © Springer International Publishing AG 2017.

According to the NMC Horizon Report (Johnson et al. in Horizon Report Europe: 2014 Schools Edition, Publications Office of the European Union, The New Media Consortium, Luxembourg, Austin, 2014 [1]), data-driven learning in combination with emerging academic areas such as learning analytics has the potential to tailor students’ education to their needs (Johnson et al. 2014 [1]). Focusing on this aim, this article presents a web-based (training) platform for German-speaking users aged 8–12.Our objective is to support primary-school pupils—especially those who struggle with the acquisition of the German orthography—with an innovative tool to improve their writing and spelling competencies. On this platform, which is free of charge, they can write and publish texts supported by a special feature, called the intelligent dictionary. It gives automatic feedback for correcting mistakes that occurred in the course of fulfilling a meaningful writing task. Consequently, pupils can focus on writing texts and are able to correct texts on their own before publishing them. Additionally, they gain deeper insights in German orthography. Exercises will be recommended for further training based on the spelling mistakes that occurred. This article covers the background to German orthography and its teaching and learning as well as details concerning the requirements for the platform and the user interface design. Further, combined with learning analytics we expect to gain deeper insight into the process of spelling acquisition which will support optimizing our exercises and providing better materials in the long run. © 2017 The Author(s)

Objective: This study aimed to identify subtypes of young moped drivers and analyze how these subtypes are involved in risk preferences and road crashes. Design: A group of Austrian teenage moped drivers (213, 28% girls) completed an online questionnaire about moped usage, injuries, driving style, inattention, impulsivity, and personality according to the Five-Factor Model of Personality and Cloninger's model of personality. Results: A cluster analysis yielded four types of moped drivers. One type was characterized by a high level of neuroticism, the second type was characterized by a risky personality and a risky driving style, the third type had a more cautious driving style, and the fourth type was characterized by a risky personality and high levels on inattention and impulsivity. Conclusions: Our conclusions suggest that young moped drivers should not be perceived as a homogenous group, according to measures of injury prevention and intervention. © 2011 Elsevier Ltd.

Austrian VET school and college students can work on industry sponsored projects in their last two semester of study, this include also chemistry and chemical engineering students. In 2011 from 22,600 teaching staff 8,000 had been teaching engineering subjects, 250 teaching chemistry and related subjects. All teaching staff is academics trained at technical universities, who had been working in industry at least for 4 years. Diploma projects are supervised by professors. To rely on the quality standards had been published already in 1999, again in 2002. More than 4000 projects are registered with htl-innovativ, an Austrian initiative listing diploma projects, 205 in the fields of chemistry. Relying on these data and on other detailed information about diploma projects in Austrian VET colleges in the last fifteen years the professionalization of the teaching staff as coaches with a focus on chemistry is studied. As in 2016 changed graduation examination rules with e From the year 2016 on changed graduation examination rules will take place at the Austrian Upper level secondary technical and vocational schools with emphasis on e. g. project work, and therefore, the professionalization of teaching staff is an important issue. © 2013 IEEE.

In recent times, online learning platforms get more and more attention and the number of collected data is growing. Learning analytics is a valuable opportunity to gain specific information for a better understanding of student’s learning behaviour and to improve their learning success. In this work, the collected data of the online learning platform is analysed and first research results are presented. The main objective is to analyse the usage behaviour over a school year and to show the diffusion of the online platform among provinces in Austria, different school types and other characteristics. Furthermore, the content of the online platform is put under closer examination to enable decisions about the efficiency and effectiveness of different types of exercises. © J.UCS.

The aim of this study was to gain insight into the compartment-specific roles of ascorbate and glutathione in leaf senescence in Arabidopsis thaliana. The subcellular distribution of ascorbate, glutathione, and hydrogen peroxide (H2O2) was analyzed by transmission electron microscopy and correlated with the activity of antioxidative enzymes in wildtype plants and the ascorbate- and glutathione-deficient mutants vtc2-1 and pad2-1, respectively. Both mutants showed earlier and stronger senescence than the wildtype indicating the importance of a functioning ascorbate and glutathione cycle in the induction and regulation of senescence. Glutathione levels dropped drastically and up to 93 % in all cell compartments of wildtype plants and the vtc2-1 mutant within the first day of dark-induced senescence while ascorbate contents remained unchanged until the very end. Glutathione contents in mitochondria of pad2-1 mutants decreased more slowly over the first 7 days than compared to the other plants indicating an important role of glutathione in mitochondria in this mutant during senescence. The strongest decrease (84 %) of glutathione contents in wildtype plants at this time point was found in mitochondria indicating an important role of mitochondria for the induction of senescence and cell death events. Due to the general decrease of the antioxidative capacity, a strong accumulation of H2O2 was observed in cell walls, plastids, and the cytosol in all plants. Activities of glutathione reductase, dehydroascorbate reductase and catalase were strongly reduced while ascorbate peroxidase and monodehydroascorbate reductase were increased. The initial rapid drop of glutathione levels seemed to be the trigger for senescence, while ascorbate appeared to be the key factor in regulating senescence through controlling H2O2 levels by the oxidation of reduced ascorbate to monodehydroascorbate and the subsequent reduction to ascorbate by monodehydroascorbate reductase. © 2016, The Author(s).

Increasing global population movement has resulted in a corresponding increase of children with severe and multiple disabilities and complex communication needs who at home are exposed to languages different from the language used at school. The aim of this study was to highlight facilitating as well as limiting factors for effective communication intervention for these children both in school and within the family. Based on observations, qualitative research interviews and analysis in the tradition of grounded theory the results indicate that the quality of parent-teacher-interaction is central to effective communication intervention and culturally sensitive use of communication aids. Challenges for teachers as well as parents to achieve a mutually satisfying interaction are addressed, and issues regarding the language use with children with severe disabilities and a multilingual and multicultural background and the inclusion of their parents in school based activities are discussed. © 2011 International Society for Augmentative and Alternative Communication.
