This paper presents the design and study of interactive user modeling to support exploratory search tasks. Contrary to traditional interactions, such as query based search, query suggestions, or relevance feedback, interactive user modeling allows users to perceive the state of a user model at all times and provide feedback that directly rewards or penalizes it. The technique allows users to co...

Mind maps have been used for many (including educational) purposes. Several tools are available for visualizing and creating those maps. However, evaluation and feedback is rarely available in such tools and thus, an important aspect of interactive exercises is missing. This paper presents the interactive concept map tool, ICMAP, that is integrated with the web-based learning environment ACTIVE...

In distance teaching, direct feedback to the students is difficult to give, but crucial for their learning success. The system Asterix was developed in order to support this direct feedback. It contains different interactive tasks from the area of the formal foundations of computer science. Asterix is available over an internet interface. The implementation of the interactive presentation and c...

Interactive surfaces and multi-touch tables are increasingly available outside academic contexts, and are entering, for instance, work or educational contexts. A large variety of applications exists for a multitude of tasks. For interacting with these applications, existing interaction concepts are often directly mapped to the multi-touch surface, which is often limited by physical constraints....

E-learning tools for mathematical problem solving such as solving linear equations should be interactive. As with pen and paper, a student constructs a solution stepwise. E-learning tools provide the capability to give feedback to a student at each step. Feedback is essential for effective learning and hence crucial for interactive e-learning tools. This paper describes a framework for providin...

Despite consensus in focus on form (FOF) instruction over the facilitative role of noticing, controversy has not quelled over ways of directing EFL learners’ attention towards formal features via implicit techniques like input-enhancement or explicit metacognitive feedback and interactive peer-editing on the output they produce. This quasi-experimental study investigated the impact of input enh...

Considering the popularity of the Internet, an automatic interactive feedback system for e-learning websites is becoming increasingly desirable. However, there are still some problems for computers to understand the natural language, especially the Chinese language. First, because the Chinese language has no space to segment the lexical entry, its segmentation method is more difficult than that...

The evolution of computer-based music systems has gone from computer-aided composition, which transposed the traditional paradigms of music composition to the digital realm, to complex feedback systems that allow for rich multimodal interactions. Yet, a lot of interactive music systems still rely on outdated principles in the light of modern situated cognitive systems design. Moreover, the role...

Age-related deficits are seen across tasks where learning depends on asocial feedback processing, however plasticity has been observed in some of the same tasks in social contexts suggesting a novel way to attenuate deficits. Socioemotional selectivity theory suggests this plasticity is due to a deliberative motivational shift toward achieving wellbeing with age (positivity effect) that reverse...
