A large number of studies carried out on pupils aged 8–14 have shown that teachable agent (TA) based games are beneficial for learning. The present pioneering study aimed to initiate research looking at whether TA based games can be used as far down as preschool age. Around the age of four, theory of mind (ToM) is under development and it is not unlikely(More)
Two groups of noise-exposed workers were compared with respect to their use of ear protectors. One group had a severe, noise-induced hearing loss; the other group had normal hearing. Both groups were composed of workers of similar age and total duration noise-exposure. It was found that those with normal hearing had used ear protectors considerably more(More)
Educational software in which the student takes the role of teacher and instructs a digital tutee – a so-called teachable agent – has repeatedly proven to have positive effects for school children's learning. In a study with 39 preschoolers aged 3:9 to 6:3, we explored the conditions under which children this young would benefit as well from this kind of(More)
Imidazolium-based ionic liquids (ILs) serve both as recyclable reaction media and as precatalysts for the N-heterocyclic carbene-catalyzed conjugate addition of α,β-unsaturated aldehydes to chalcones. The reaction produces a broad scope of 1,6-ketoesters incorporating an anti-diphenyl moiety in high yields and with high stereoselectivity. In recycling(More)
