Creative u-learning: kompleksowe zastosowanie narzędzi ICT w Centrum Językowym Uniwersytetu Masaryka w Brnie

This paper analyses the implementation of ICT enhanced complex, flexible and individualised language learning in the university environment with the aim to share its effectiveness. Masaryk University Language Centre (CJV) engages in teaching and research activities closely related to the development and use of ICT and multimedia in general. A wide range of synchronous and asynchronous communication tools (Facebook, chat, video conferencing and email, forum, blog, YouTube) combined with individual and collaborative activities within an LMS (Moodle, IS MU) and outside offers new opportunities to the improvement of foreign language learning. The presentation of three types of CJV courses analyses individual tools and focuses on various approaches aiming at deeper involvement of university students in real academic or expert situations as well as their intensive engagement in an environment where they can test and improve their language, expert and socio-cultural skills

Crosslinking of epoxy-polysiloxane system by reactive blending

(PAMS) containing pendant amino groups and diglycidyl ether of Bisphenol A (DGEBA). The initially immiscible blend is compatibilized during the reaction and crosslinked. Network formation, dynamics of the system and evolution of morphology were determined by dynamic mechanical analysis and light scattering techniques. The grafting epoxy-amine reaction involves a high extent of cyclization resulting in a high fraction of the sol in the networks. Dynamic light scattering data analysis reveals fast and slow relaxation modes of reacting species in the pregel and one single mode in the post-gel state. The network with a stoichiometric composition shows the most homogeneous morphology with a single glass transition temperature. On the contrary, the networks with excess of PAMS are strongly phase-separated exhibiting the unreacted PAMS-rich phase, PAMS phase partly grafted with epoxide and PAMS-DGEBA crosslinked phase.The authors acknowledge financial support of the European Commission through a Marie Curie Training Site contract No. HPMT-CT-2001-00396 and of the Grant Agency of Academy of Sciences of the Czech Republic (A4050008).Publicad
