The introduction of computer-supported collaborative learning (CSCL), specifically into intercultural learning environments, mirrors the largely internet-based and intercultural workplace of many professionals. This paper utilized a mixed methods approach to examine differences between students’ perceptions of collaborative learning, their reported learning experiences, and learning outcomes wh...

The link between affect and student learning has been the subject of increasing attention in recent years. Affective states such as flow and curiosity tend to have positive correlations with learning while negative states such as boredom and frustration have the opposite effect. Consequently, it is a goal of many intelligent tutoring systems to guide students toward emotional states that are co...

Sample efficiency is an important topic in reinforcement learning. With limited data and experience, how can we converge to a good policy more quickly? In this paper, we propose a new experience replay method called Reward Backpropagation, which gives higher minibatch sampling priority to those (s, a, r, s′) with r 6= 0 and then propagate the priority backward to its previous transition once it...

Subjective Well-being(SWB), which refers to how people experience the quality of their lives, is of great use to public policy-makers as well as economic, sociological research, etc. Traditionally, the measurement of SWB relies on time-consuming and costly self-report questionnaires. Nowadays, people are motivated to share their experiences and feelings on social media, so we propose to sense S...

In the CLEF 2005 initiative, multlingual web retrieval was integrated as a task for the first time. This paper describes experiments based on one multilingual index carried out at the University of Hildesheim. Several indexing strategies based on a multi-lingual index have been tested with the EuroGOV corpus. Boosting topic fields with higher weight led to best results during post submission ru...

Experience replay lets online reinforcement learning agents remember and reuse experiences from the past. In prior work, experience transitions were uniformly sampled from a replay memory. However, this approach simply replays transitions at the same frequency that they were originally experienced, regardless of their significance. In this paper we develop a framework for prioritizing experienc...

The editorial provides a background for the special issue on Problem Based Learning and ICT and focuses on three core themes: Problem Based Learning (PBL) and its background and pedagogical principles; learning characteristics of information and communication technology (ICT); and intercultural perspectives. The editorial presents a Danish perspective on PBL based on the long tradition for PBL ...

While effective distance education has been practiced and studied for centuries, it has been in just the last decade that networked digital technology has been employed. Technologies and teaching techniques continue to evolve, and the options continue to expand, emphasizing the need for information that will assist distance education planners and participants in making decisions that will resul...

A remarkable ability of the cognitive system is the creation of new knowledge based on prior experiences. What cognitive mechanisms support such knowledge creation? We propose that statistical learning not only extracts existing relationships between objects, but also generates new associations between objects that have never been directly associated. Participants viewed a continuous color sequ...

Measuring the efficacy of ITS can be hard because there are many confounding factors: short, well-isolated studies suffer from insufficient interaction with the system, while longer studies may be affected by the students’ other learning activities. Coarse measurements such as preand post-testing are often inconclusive. Learning curves are an alternative tool: slope and fit of learning curves s...
