In this context, the International Computer and Information Literacy Study (IEA-ICILS 2018) has identified substantial social disparities concerning computer and information literacy of grade 8 students. Furthermore, it has been observed that many schools, especially those located in socioeconomically challenged areas, are particularly engaged in supporting students’ digital literacy and innovatively designing learning processes with information and communications technology (ICT). Empirical studies have made it apparent that some schools have high average achievements concerning domains such as reading literacy and mathematics in spite of socioeconomically challenged student bodies. These schools are regarded as being organizationally resilient. This contribution focusses on these organizationally resilient schools with regard to the domain of computer and information literacy. It aims to investigate how these schools can be classified as a typology according to selected school and/or teacher characteristics. Methods As a first step, representative samples of IEA-ICILS 2018 are used to identify organizationally resilient schools by using students’ achievement measures (plausible values) and their background information regarding their families’ socio-economic status. In order to develop a typology, latent profile analyses (LPA) are conducted by using input and process indicators on the school level, which have been proven to be relevant for implementation through existing empirical research. Results About one twentieth of the schools examined in this contribution can be regarded as organizationally resilient and can be allocated onto a typology of three school types that are characterized by different school-level factors. Conclusions The international comparison permits the conclusion that the phenomenon of organizational resilience is also existent with regard to the content domain of computer and information literacy. However, the proportion of resilient schools is subject to considerable variation between countries. }}, author = {{Drossel, Kerstin and Eickelmann, Birgit and Vennemann, Mario}}, issn = {{2196-0739}}, journal = {{Large-scale Assessments in Education}}, pages = {{1--19}}, title = {{{Schools overcoming the digital divide: in depth analyses towards organizational resilience in the computer and information literacy domain}}}, doi = {{10.1186/s40536-020-00087-w}}, volume = {{8}}, year = {{2020}}, } @inbook{27840, author = {{Vennemann, Mario and Drossel, Kerstin and Eickelmann, Birgit}}, booktitle = {{ICILS 2018 #NRW.

(2019). Preparing for life in a digital world: IEA International Computer and Information Literacy Study 2018 International Report. Amsterdam: International Association for the Evaluation of Educational Achievement (IEA). Retrieved from https://www.iea.nl/sites/default/files/2019-11/ICILS%202019%20Digital%20final%2004112019.pdf). Educational systems play a key role in the mediation of these skills (Eickelmann. Second Handbook of Information Technology in Primary and Secondary Education. Cham: Springer, 2018). However, previous studies have shown differences in students’ computer and information literacy (CIL). Although various approaches have been used to explain these differences, process data, such as response times, have never been taken into consideration. Based on data from the IEA-study ICILS 2013 of the Czech Republic, Denmark and Germany, this secondary analysis examines to what extent response times can be used as an explanatory approach for differences in CIL also within different groups of students according to student background characteristics (gender, socioeconomic background and immigrant background). Methods First, two processing profiles using a latent profile analysis (Oberski, D. (2016). Mixture Models: Latent Profile and Latent Class Analysis. In J. Robertson & M. Kaptein (Eds.), Modern Statistical Methods for HCI (pp. 275–287). Switzerland: Springer. 10.1007/978-3-319-26633-6) based on response times are determined—a fast and a slow processing profile. To detect how these profiles are related to students’ CIL, also in conjunction with students’ background characteristics (socioeconomic and immigrant background), descriptive statistics are used. Results The results show that in the Czech Republic and Germany, students belonging to the fast processing profile have on average significantly higher CIL than students allocated to the slow processing profile. In Denmark, there are no significant differences. Concerning the student background characteristics in the Czech Republic, there are significant negative time-on-task effects for all groups except for students with an immigrant background and students with a high parental occupational status. There are no significant differences in Denmark. For Germany, a significant negative time-on-task effect can be found among girls. However, the other examined indicators for Germany are ambiguous. Conclusions The results show that process data can be used to explain differences in students’ CIL: In the Czech Republic and Germany, there is a correlation between response times and CIL (significant negative time-on-task effect). Further analysis should also consider other aspects of CIL (e.g. reading literacy). What becomes clear, however, is that when interpreting and explaining differences in competence, data should also be included that relates to the completion process during testing. }}, author = {{Heldt, Melanie and Massek, Corinna and Drossel, Kerstin and Eickelmann, Birgit}}, issn = {{2196-0739}}, journal = {{Large-scale Assessments in Education}}, pages = {{1--20}}, title = {{{The relationship between differences in students’ computer and information literacy and response times: an analysis of IEA-ICILS data}}}, doi = {{10.1186/s40536-020-00090-1}}, volume = {{8}}, year = {{2020}}, } @article{27865, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, journal = {{SchulVerwaltung Baden-Württemberg}}, number = {{12}}, pages = {{328--331}}, title = {{{Schulschließungen und Perspektiven für die Pandemie-Zeit}}}, volume = {{29}}, year = {{2020}}, } @inbook{27866, author = {{Drossel, Kerstin and Eickelmann, Birgit}}, booktitle = {{Mobile Medien im Schulkontext (Reihe Medienbildung und Gesellschaft)}}, editor = {{Meister, Dorothee M. and Midt, Ilka}}, pages = {{135--153}}, publisher = {{Springer}}, title = {{{Der Einsatz von Tablets am Gymnasium und der Zusammenhang mit der Entwicklung computerbezogener Kompetenzen von Schüler*innen}}}, year = {{2020}}, } @inbook{27867, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, booktitle = {{Encyclopedia of Education and Information Technologies}}, editor = {{Tatnall, Arthur}}, isbn = {{9783030105754}}, pages = {{1577--1589}}, publisher = {{Springer}}, title = {{{Students’ computer literacy and the use of tablets in upper secondary schools}}}, doi = {{10.1007/978-3-030-10576-1}}, year = {{2020}}, } @book{27869, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, publisher = {{Vodafone Stiftung}}, title = {{{Digitales Potenzial.

Most standard-model VRFs rely on admissible hash functions (AHFs) to achieve security against adaptive attacks in the standard model. Known AHF constructions are based on error-correcting codes, which yield asymptotically efficient constructions. However, previous works do not clarify how the code should be instantiated concretely in the real world. The rate and the minimal distance of the selected code have significant impact on the efficiency of the resulting cryptosystem, therefore it is unclear if and how the aforementioned constructions can be used in practice. First, we explain inherent limitations of code-based AHFs. Concretely, we assume that even if we were given codes that achieve the well-known Gilbert-Varshamov or McEliece-Rodemich-Rumsey-Welch bounds, existing AHF-based constructions of verifiable random functions (VRFs) can only be instantiated quite inefficiently. Then we introduce and construct computational AHFs (cAHFs). While classical AHFs are information-theoretic, and therefore work even in presence of computationally unbounded adversaries, cAHFs provide only security against computationally bounded adversaries. However, we show that cAHFs can be instantiated significantly more efficiently. Finally, we use our cAHF to construct the currently most efficient verifiable random function with full adaptive security in the standard model.}}, author = {{Jager, Tibor and Niehues, David}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{9783030384708}}, issn = {{0302-9743}}, keywords = {{Admissible hash functions, Verifiable random functions, Error-correcting codes, Provable security}}, location = {{Waterloo, Canada}}, title = {{{On the Real-World Instantiability of Admissible Hash Functions and Efficient Verifiable Random Functions}}}, doi = {{10.1007/978-3-030-38471-5_13}}, year = {{2020}}, } @article{17359, abstract = {{In this article, we focus on the acceleration of a chemical reaction simulation that relies on a system of stiff ordinary differential equation (ODEs) targeting heterogeneous computing systems with CPUs and field-programmable gate arrays (FPGAs).

Viele technologische Entwicklungen führen auf der einen Seite zu bereichernden Formen der Lebensgestaltung und Erhöhung der Lebensqualität, auf der anderen Seite stellen sie Selbstbestimmung, Teilhabe und Autonomie aber auch grundlegend in Frage. Wenngleich zwar der Begriff Digitalisierung im engeren technischen Sinne die Überführung von analogen Erscheinungsformen in digitale Daten – also elektronisch gespeicherte Zeichen, die in programmierbaren Computern maschinell verarbeitet werden können – beschreibt, werden die damit verbundenen Transformationsprozesse in ihrer gesellschaftlichen und (medien-)pädagogischen Bedeutung erst deutlich ,wenn man die Dimensionen der Vernetzung, der zunehmenden Generierung von Daten durch aktive (eigene) Produktion oder durch sensorische Systeme und die Algorithmisierung von Prozessen, insbesondere auch im Kontext selbstlernender Systeme, in den Blick nimmt. Orientierung wird hier nicht nur in Bezug auf die technologischen Entwicklungen zu einer zunehmenden Herausforderung, sondern auch mit Blick auf die dadurch einem dynamischen und fortlaufenden Wandel unterliegenden Medienwelten. Die stetig zunehmende Bedeutung der Digitalisierung für Individuum und Gesellschaft kann mit der Chiffre «permanent online, permanent verbunden» umsponnen werden. Mit mobilen Endgeräten – insbesondere Smartphones, die leistungsfähigen Computern in ihren Funktionalitäten in nichts nachstehen – sind wir heute zu jeder Zeit und an nahezu jedem Ort der Welt miteinander vernetzt und haben Zugriff auf eine enorme Menge von Medienangeboten. Gleichzeitig produzieren wir eine enorme Menge an Daten, die nicht nur funktionale Bedeutung haben, sondern insbesondere ökonomische und (gesellschafts-)politische. Auch das soziale Beziehungsgefüge, der Lebenswandel und Lebensstil verändern sich. Die damit verbundenen Möglichkeiten changieren zwischen Hoffnung und Sorge, Chance und Risiko, Mündigkeit und Unmündigkeit oder kurzum kann von einem durch ein einerseits-andererseits geprägten Spannungsfeld gesprochen werden. Von der Medienpädagogik darf zurecht erwartet werden, im Strom dieser hohen Dynamik und den oftmals enorm kurzen Innovationszyklen von Entwicklungen in mindestens zweierlei Hinsicht Orientierungen zu bieten: zum einen im Hinblick auf die für eine Orientierung in der digitalen Welt notwendigen oder angemessenen individuellen und kollektiven Bildungsressourcen; zum anderen im Hinblick auf die pädagogischen Zugänge und Massnahmen zur Ermöglichung von Orientierung sowie damit verbundene Forschungen. Gleichzeitig drängt sich die Frage auf, welchen Einfluss Medienpädagogik auf die Gestaltung von zukünftigen Entwicklungen nimmt oder nehmen kann. Können angesichts der Komplexität von (digitalen) Medien bzw. der damit verbundenen technologischen Strukturen, kulturellen Praxen, ökonomischen Bedingungen und gesellschaftlichen Implikationen solche Orientierungsleistungen – die sich auf eine im Grunde nur interdisziplinär beschreib- und verstehbare digitale Welt beziehen – überhaupt von einer Medienpädagogik als genuin erziehungswissenschaftliche Disziplin eigenständig erbracht werden? Welchen Beitrag kann Medienpädagogik in dieser interdisziplinären Gemengelage leisten? Und noch grundsätzlicher könnte danach gefragt werden, was Orientierung und Gestaltungsmöglichkeiten angesichts der Unbestimmtheit von Entwicklungen eigentlich bedeuten. Ausgehend von diesen Perspektiven und Erwägungen hat die Frühjahrstagung 2019 der Sektion Medienpädagogik folgende Fragen in den Mittelpunkt gestellt: Welche Rolle spielt die Medienpädagogik in interdisziplinären Kontexten von Mediatisierung und Digitalisierung? Welche Rolle nimmt die Medienpädagogik bei der Gestaltung von zukünftigen Entwicklungen ein? Welchen Beitrag kann die Medienpädagogik in innovativen Feldern, wie z.B. VR/AR oder KI leisten?
