This app offers free exercises on Granima grammar animations. The animations for the exercises can be found in the "Granima - the grammar studio" app and on our website (https://granima.de). There you can also download a free demo package. As part of the project "Animated Basic Grammar of the German Language" by Prof. dr. Jörg Roche is developing an innovative basic grammar of the German language at the Institute for German as a Foreign Language of the LMU Munich, which is based on findings from cognitive linguistics and multimedia learning. The Current Grammar Studio presents German grammar with sports imagery. The sports are animated and explained as grammatical metaphors. These computer animations are particularly suitable for clarifying the rules, especially for learners who have been "fighting" grammar for a long time. The grammar studio is a reference grammar. It also contains notes for use in the classroom and exercises. Through the website https: //granima.de and via the "Granima - das Grammatikstudio" app, language lessons, language teachers and language learners can book individual animations as well as packages for numerous grammatical phenomena in the German language. Three types of animations are used: semantic explanations (as in the meaning of prepositions), conceptual (as in the case of crossover in the case of alternate prepositions), and topological explanations (as in the explanation of the verbal elements in word formation). Often all three variants are used for the explanation. The conceptual presentation is based on findings of cognitive linguistics. It is the most important reference discipline for cognitive language didactics and can be very well combined with action-oriented didactics. Grammar is presented as a holistic, meaningful and transparent system. The positive and lasting impact of the conceptual approach has been clearly demonstrated in numerous scientific studies of proficiency in various grammatical areas.
