Due to increasing numbers of students at German universities large-scale learning services are still a common default. These learning services lack interaction as well as feedback to assess learners’ knowledge on the cognitive levels of educational objectives. This situation is alarming, since interaction and feedback in order to assess the own learning progress are important factors for indivi...

The purpose of this paper was to explore research-based applications for using video podcasts in an online learning environment. Five key video podcast uses were examined including administration, instruction, student assignments, feedback, and community. Administrative video podcasts provide course information on areas such as learning goals, lesson plan instructions, course policies, and home...

Creating up-to-date high quality learning materials requires significant resources many instructors cannot afford, especially when it comes to appealing eLearning materials. Peer creation may help to address this challenge. However, existing concepts of peer learning focus mostly on enhancing active discussion and reflection. Thus far, little to no research has addressed processes of systematic...

We are interested in three technologies, Semantic web and ontologies to deliver peer assessment as part of Inquiry based learning (IBL) environment. Introducing peer assessment can be a way to force students to take the responsibility to make a judgment about the actual contribution of each of their peers and to enrich their knowledge by assessing the work done by other learners. Delivery of pe...

The purpose of this study is to explore the effectiveness of peer learning in an AR-based learning environment to learn science concepts. Augmented reality (AR) is an advanced technology with which users can interact with 3-D objects and the real world at the same time. Ninety sixty subjects participated in this study. They were randomly assigned to three groups: individual learning with AR, pe...

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...
