Aus diesem Grund erscheint es uns immens wichtig, diese Fragestellungen und Technologien auch in den Unterricht der Sekundarstufe II zu integrieren. Um diesem Anspruch gerecht zu werden, entwickelten wir im Rahmen eines Forschungsprojekts ein Curriculum, welches wir als konkretes Unterrichtskonzept innerhalb eines Projektkurses erprobt, evaluiert weiterentwickelt wird. Bei der Implementierung entschieden wir uns, zur aktiven Umsetzung von Konzepten von ML als Plattform Jupyter Notebook mit Python zu verwenden, da diese Umgebung durch die Verbindung von Code und Hypertext zur Dokumentation und Erklärung Medienbrüche im Lernprozess verringern kann. Zudem ist Python zur Implementierung der Methoden von ML sehr gut geeignet. Im Themenfeld des ML als Teilgebiet der KI legen wir den Fokus auf zwei unterschiedliche Lernverfahren um verschieden Aspekte von ML, u.A. wie Nachvollziehbarkeit unter gesellschaftlichen Gesichtspunkten zu vermitteln. Diese sind Künstliche Neuronale Netze (bei denen die Berechnung und Bedeutung der Kantengewichte zwischen den Neuronen für den Menschen insbesondere bei komplexeren Netzen kaum nachvollziehbar erschienen) und Entscheidungsbäume (strukturierte und gerichtete Bäume zur Darstellung von Entscheidungsregeln, welche auch für Schülerinnen und Schüler meist gut nachvollziehbares und verständliches KI-Modell darstellen). In diesem Workshop stellen wir konkrete Umsetzungsbeispiele inklusive der Programmierung für beide Verfahren mit Jupyter Notebook und Python als Teil einer Unterrichtssequenz vor und diskutieren diese."}],"publication":"Informatik für alle","language":[{"iso":"ger"}],"main_file_link":[{"url":"https://dl.gi.de/handle/20.500.12116/28964"}],"publication_status":"published","date_updated":"2025-05-25T20:01:30Z","author":[{"first_name":"Michael","last_name":"Schlichtig","orcid":"0000-0001-6600-6171","full_name":"Schlichtig, Michael","id":"32312"},{"full_name":"Opel, Simone","last_name":"Opel","first_name":"Simone"},{"last_name":"Schulte","first_name":"Carsten","full_name":"Schulte, Carsten"},{"full_name":"Biehler, Rolf","first_name":"Rolf","last_name":"Biehler"},{"last_name":"Frischemeier","first_name":"Daniel","full_name":"Frischemeier, Daniel"},{"full_name":"Podworny, Susanne","last_name":"Podworny","first_name":"Susanne"},{"full_name":"Wassong, Thomas","first_name":"Thomas","last_name":"Wassong","id":"21241"}],"publication_identifier":{"isbn":["978-3-88579-682-4"]},"title":"Maschinelles Lernen im Unterricht mit Jupyter Notebook","year":"2019"},{"status":"public","title":"Doctor blade system for the deposition of thin semiconducting films","year":"2019","author":[{"id":"8282","last_name":"Petrov","first_name":"Dmitry","full_name":"Petrov, Dmitry"},{"first_name":"Thorsten","last_name":"Meyers","full_name":"Meyers, Thorsten"},{"last_name":"Reker","first_name":"Julia","full_name":"Reker, Julia"},{"full_name":"Hilleringmann, Ulrich","last_name":"Hilleringmann","first_name":"Ulrich","id":"20179"}],"date_updated":"2026-02-24T19:14:18Z","publication_status":"published","_id":"59781","publisher":"SPIE","language":[{"iso":"eng"}],"doi":"10.1117/12.2501307","user_id":"8282","editor":[{"full_name":"du Plessis, Monuko","first_name":"Monuko","last_name":"du Plessis"}],"publication":"Fifth Conference on Sensors, MEMS, and Electro-Optic Systems","citation":{"short":"D.

The introduction of novel concepts in laser operation thus has potential to lead to both new applications and fundamental insights2. Spintronics3, in which both the spin and the charge of the electron are used, has led to the development of spin-lasers, in which charge-carrier spin and photon spin are exploited. Here we show experimentally that the coupling between carrier spin and light polarization in common semiconductor lasers can enable room-temperature modulation frequencies above 200 gigahertz, exceeding by nearly an order of magnitude the best conventional semiconductor lasers. Surprisingly, this ultrafast operation of the resultant spin-laser relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both of which are commonly viewed as detrimental in spintronics3 and conventional lasers4. Our results overcome the key speed limitations of conventional directly modulated lasers and offer a prospect for the next generation of low-energy ultrafast optical communication.","lang":"eng"}],"extern":"1","publication":"Nature","issue":"7751","department":[{"_id":"977"}],"type":"journal_article","date_created":"2025-04-25T07:21:34Z","status":"public","volume":568,"user_id":"15911","_id":"59687","publisher":"Springer Science and Business Media LLC","page":"212-215","quality_controlled":"1","citation":{"mla":"Lindemann, Markus, et al. “Ultrafast Spin-Lasers.” <i>Nature</i>, vol. 568, no. 7751, Springer Science and Business Media LLC, 2019, pp. 212–15, doi:<a href=\"https://doi.org/10.1038/s41586-019-1073-y\">10.1038/s41586-019-1073-y</a>.","ama":"Lindemann M, Xu G, Pusch T, et al.

It is emerging as a suitable technology for teaching psychomotor skills. Simultaneously, gamification has become increasingly popular in the teaching field, providing famous examples, such as Duolingo (for the acquisition of foreign languages) or Codecademy (for learning programming languages) [3]. Many papers have already highlighted the beneficial aspects of gamification and AR for education and teaching (e.g. [1, 2, 4, 5]. While gamification is useful for improving students’ motivation and engagement, AR can be applied to teach them operational skills without any time, costs and place constraints. Hence, this opens up numerous possibilities and forms to combine these two aspects (AR and gamification) for higher education teaching. However, there has been less research focusing on how gamification and AR can be combined in a useful manner to keep up students’ initial motivation aroused through novelty effects of AR learning environments. Accordingly, this paper will present such a gamification concept for an AR based virtual preparation laboratory training to overcome the risk of demotivation, once AR will settle as a mainstream technology such as learning videos. The focus of the AR-App – presently being developed at the University of Paderborn – is to remedy the students’ lack of practical skills when operating electro-technical laboratory equipment during their compulsory laboratory training.","lang":"eng"}],"publication":"The Challenges of the Digital Transformation in Education","doi":"10.1007/978-3-030-11932-4_54","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2024-12-29T11:09:43Z","title":"Gamification in an Augmented Reality Based Virtual Preparation Laboratory Training","year":"2019","publication_identifier":{"issn":["2194-5357","2194-5365"],"isbn":["9783030119317","9783030119324"]},"author":[{"id":"11763","full_name":"Alptekin, Mesut","last_name":"Alptekin","first_name":"Mesut"},{"full_name":"Temmen, Katrin","last_name":"Temmen","first_name":"Katrin","id":"30086"}],"place":"Cham","file_date_updated":"2024-12-29T11:07:54Z","citation":{"short":"M.
