Nahližime-li vsak toto tema pedagogickým uhlem pohledu, pak nelze jednoduse přehlednout minulost a tradici ve vzdělavani, ktera může být zdrojem zajimavých poznatků ci inspiraci k přemýsleni. V prvni casti přispěvku se proto autor věnuje minulosti, kde ukaže některe pedagogicke nazory ci teorie, ktere svým způsobem spoluvytvařeji tradici. V dalsi casti textu se zaměři na soucasnost, přicemž se zaměři na klicove aktery e-learningu – ucitele a studenta. Na zakladě ceských i zahranicnich výzkumů ukaže problematiku e-learningu z poněkud jineho uhlu pohledu než býva běžne. V zavěrecne casti bude pozornost věnovana budoucnosti, kterou je možne jen stěži přesně předpovidat. Je vsak možne alespoň naznacit budouci trendy v e-learningu.

MIR aims at searching information in documents with significant amount of mathematical content in the form of expressions and formulae. Based on the newly established international MIR evaluation forum and on the number of MIR related research groups around the world, it is definitely on the rise. In this work I have summarized and compared different approaches to math-aware search systems. More detailed description of Math Indexer and Searcher (MIaS) was provided as this is our system created at Faculty of Informatics, Masaryk University, primarily designed and developed by me. MIaS is currently reported as the best performing MIR system in terms of effectiveness. In this work I proposed several topics which are main research interests of my studies. The topics correlate with possible features that can improve the effectiveness of MIR systems. Namely, the proposed topics are math formula substree unification, integration of algebraic computational power into the indexing as well as searching phase, query expansion as a way of increasing recall, query variables, combination of more approaches within one system and a utilization of combination of text and math search. One topic that spans over all other topics is evaluation which is a necessity in a process of continuous improvement of effectiveness.

The demonstrations presented did not appear in the printed version of the Proceedings of GWC 2004. The authors of the demonstrations provided an abstract, that appears in the CD version of the Proceedings. The Proceedings was published by Masaryk University in both paper and CD format.
