Davis, D.J. (author), Triglianos, V. (author), Hauff, C. (author), Houben, G.J.P.M. (author)Past research in large-scale learning environments has found one of the most inhibiting factors to learners’ success to be their inability to effectively self-regulate their learning efforts. In traditional small-scale learning environments, personalized feedback (on progress, content, behavior, etc.) has been found to be an effective solution...conference paper 2018

R. (author)The potential of shale reservoirs for gas extraction is largely determined by the permeability of the rock. Typical pore diameters in shales range from the μm down to the nm scale. The permeability of shale reservoirs is a function of the interconnectivity between the pore space and the natural fracture network present. We have measured the...journal article 2017

Chen, G. (author), Davis, D.J. (author), Krause, Markus (author), Hauff, C. (author), Houben, G.J.P.M. (author)Massive Open Online Courses (MOOCs) aim to educate the world, especially learners from developing countries. While MOOCs are certainly available to the masses, they are not yet fully accessible. Although all course content is just clicks<br/>away, deeply engaging with a MOOC requires a substantial time commitment, which frequently becomes a...conference paper 2017

Davis, D.J. (author), Jivet, I. (author), Kizilcec, René F. (author), Chen, G. (author), Hauff, C. (author), Houben, G.J.P.M. (author)Social comparison theory asserts that we establish our social and personal worth by comparing ourselves to others. In in-person learning environments, social comparison offers students critical feedback on how to behave and be successful. By contrast, online learning environments afford fewer social cues to facilitate social comparison. Can...conference paper 2017

Pradena, M.A. (author), Houben, L.J.M. (author)During the construction of Jointed Plain Concrete Pavements (JPCPs) in Chile, it was observed that joints remained uncracked. The objectives of this paper are to evaluate the effects of uncracked joints (UnCrJ) in JPCPs and to propose possible solutions or improvements to avoid or minimize this phenomenon. Considering low thermal amplitude as...journal article 2016

Dhiratara, Arkka (author), Yang, J. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)Social media data are increasingly used as the source of research in a variety of domains. A typical example is urban analytics, which aims at solving urban problems by analyzing data from different sources including social media. The potential value of social media data in tourism studies, which is one of the key topics in urban research,...journal article 2016

Zhubayev, A. (author), Houben, M.E. (author), Smeulders, D.M.J. (author), Barnhoorn, A. (author)We have conducted ultrasonic experiments, between 0.3 and 1 MHz, to measure velocity and attenuation (Q?1) anisotropy of P- and S-waves in dry Whitby Mudstone samples as a function of stress. We found the degree of anisotropy to be as large as 70% for velocity and attenuation. The sensitivity of P-wave anisotropy change with applied stress is...journal article 2015

Pradena, M. (author), Houben, L.J.M. (author)Concrete pavements (CPs) are durable and they do not need periodic invasive maintenance interventions. Nevertheless, CPs are hardly chosen when only initial costs, instead of life-cycle costs, are considered in the evaluation. Nowadays, there are innovations in Jointed Plain Concrete Pavements (JPCPs) that reduce initial costs about 25% with...conference paper 2014

By formulating questions, users express needs that other members of the cQA community try to collaboratively satisfy. Poorly formulated questions are less likely to receive useful responses, thus hindering the overall knowledge generation...conference paper 2014

In such pavements the role of granular layers is very important in the general performance of the structure. Pavement designs in these countries are empirical in nature and rely on...journal article 2012

Akbarnejad, S. (author), Copuroglu, O. (author), Houben, L.J.M. (author), Molenaar, A.A.A. (author)In congested areas around the world, traffic has significantly grown beyond expectation both in terms of volume and weight. Any hinder to the traffic causes severe delays resulting not only in economic loss but also in extra pollution of the environment. Therefore, maintenance works are desired to be reduced as much as possible. Application of...conference paper 2012
