A Simple Computer Game for Learning Mathematics

It is sometimes unquantifiable how hard it is for most people to deal with game addiction. Several articles have equally been published to address this subject, some suggesting the concept of Educational and serious games. Similarly, researchers have revealed that it does not come easy learning a subject like math. This is where the illusive world of computer games comes in. It is amazing how much people learn from games. In this paper, we have designed and programmed a simple PC math game that teaches rudimentary topics in mathematics.

The E-learning Circle – a holistic software design tool for e-learning

The article introduces the E-learning Circle, a tool developed to assure the quality of the software design process of e-learning systems, considering pedagogical principles as well as technology. The E-learning Circle consists of a number of concentric circles which are divided into three sectors. The content of the inner circles is based on pedagogical principles, while the outer circle specifies how the pedagogical principles may be implemented with technology. The circle’s centre is dedicated to the subject taught, ensuring focus on the specific subject’s properties. The three sectors represent the student, the teacher and the learning objectives. The strengths of the E-learning Circle are the compact presentation combined with the overview it provides, as well as the usefulness of a design tool dealing with complexity, providing a common language and embedding best practice. The E-learning Circle is not a prescriptive method, but is useful in several design models and processes. The article presents two projects where the E-learning Circle was used as a design tool.

Successful computer-supported distance education requires that its enabling technologies are accessible and usable anywhere. They should work seamlessly inside and outside the information superhighway, wherever the target learners are located, without obtruding on the learning activity. It has long been recognised that the usability of interactive computer systems is inversely related to the visibility of the implementing technologies. Reducing the visibility of technology is especially challenging in the area of online language learning systems, which require high levels of interactivity and communication along multiple dimensions such as speaking, listening, reading and writing. In this article, the authors review the concept of invisibility as it applies to the design of interactive technologies and appliances. They describe a specialised appliance matched to the requirements for distance second language learning, and report on a successful multi-phase evaluation process, including initial field testing at a Thai open university.

Abstrahierendes Lernen durch aktive Modellbildung: Evaluation eines Prozesses und einer Lernumgebung

Die Fähigkeit zum Lernen durch Abstraktion aus Erfahrungen unterscheidet Experten von Novizen. Wir stellen einen Prozess für individuelles abstrahierendes Lernen und eine diesen Prozess unterstützende Lernumgebung vor. Die Ergebnisse einer Pilotstudie zeigen, dass Lernende unter Nutzung der Lernumgebung aus Fallbeispielen ein abstraktes Modell erstellen und über ihren Prozess reflektieren konnten. Dies fiel ihnen leichter, wenn die Fallbeispiele wenige gemeinsame Oberflächenmerkmale aufwiesen. Im Gegensatz zum intendierten Lernprozess wandten manche Lernende einen anderen Prozess an.

Besonderheiten bei der Auslegung und Gestaltung lasergesinterter Bauteile

Mit der Entwicklung der losgrößenunabhängigen, additiven Fertigungsverfahren eröffnen sich vollkommen neue Wege zur Realisierung von komplexen Integralbauteilen bei niedrigen Stückzahlen. Bei der Bauteilgestaltung müssen (verglichen mit traditionellen Herstellverfahren, beispielsweise Spritzgießen) weniger Fertigungsrestriktionen beachtet werden. Dennoch ist die Gestaltungsfreiheit nicht unbegrenzt. In diesem Beitrag werden basierend auf dem Gedanken des Fertigungsgerechten Konstruierens Möglichkeiten und Herausforderungen bei der Gestaltung von additiv gefertigten Bauteilen herausgestellt. Darauf aufbauend werden Potenziale aufgezeigt, wie Produktentwickler in Zukunft bei der Auslegung und Gestaltung solcher Produkte unterstützt werden können.

Action Research and Learning Analytics in Higher Education

Teaching is a dynamic activity. It can be very effective, if its impact is constantly monitored and adjusted to the demands of changing social contexts and needs of learners. This implies that teachers need to be aware about teaching and learning processes. Moreover, they should constantly question their didactical methods and the learning resources, which they provide to their students. They should reflect if their actions are suitable, and they should regulate their teaching, e.g., by updating learning materials based on new knowledge about learners, or by motivating learners to engage in further learning activities. In the last years, a rising interest in ‘learning analytics’ is observable. This interest is motivated by the availability of massive amounts of educational data. Also, the continuously increasing processing power, and a strong motivation for discovering new information from these pools of educational data, is pushing further developments within the learning analytics research field. Learning analytics could be a method for reflective teaching practice that enables and guides teachers to investigate and evaluate their work in future learning scenarios. However, this potentially positive impact has not yet been sufficiently verified by learning analytics research. Another method that pursues these goals is ‘action research’. Learning analytics promises to initiate action research processes because it facilitates awareness, reflection and regulation of teaching activities analogous to action research. Therefore, this thesis joins both concepts, in order to improve the design of learning analytics tools. Central research question of this thesis are: What are the dimensions of learning analytics in relation to action research, which need to be considered when designing a learning analytics tool? How does a learning analytics dashboard impact the teachers of technology-enhanced university lectures regarding ‘awareness’, ‘reflection’ and ‘action’? Does it initiate action research? Which are central requirements for a learning analytics tool, which pursues such effects? This project followed design-based research principles, in order to answer these research questions. The main contributions are: a theoretical reference model that connects action research and learning analytics, the conceptualization and implementation of a learning analytics tool, a requirements catalogue for useful and usable learning analytics design based on evaluations, a tested procedure for impact analysis, and guidelines for the introduction of learning analytics into higher education.
