Abstract This paper introduces a tool enabling e-learning of modelling and simulation in a user-friendly and unique way – the MMT system. MMT stands for Mathematics, Modelling and Tools. One of the things taught with the help of the MMT system is lectures of basic mathematics, where students can experiment with MMT examples concerning Analysis and Linear Algebra to strengthen their understanding of the current subject of the lecture. The most important use of the MMT server lies in the support of teaching modelling and simulation. By varying the input parameters of models on the MMT server students can find out in which way they affect the simulation. To enable profound understanding of the models, all source codes are offered to be downloaded from the MMT system. The paper starts with a simple example to become acquainted with the MMT environment and understand the interaction of the MMT example with the corresponding function. One of the latest achievements within the MMT system has been the successful inclusion of examples accessing several m-files and further even Simulink models. The communication between the MMT server and a Simulink model is realised in a m-file exchanging parameters and output among the model and the respective MMT example. The last part of the paper discusses the use of the MMT system in exams, which is realised by the e-learning platform TUWEL. Via this tool students are asked to find out specific data coordinates or input values for a given problem on the MMT server.
