This paper deals with the evaluation of innovative e-learning materials that were created within the project "Exemplary developmental projects from industry for reinforcing the practical knowledge of future mechanical engineers" at the University of West Bohemia in Pilsen (UWB) at the Faculty of Mechanical Engineering (FME) in the Department of Machine Design (DMD). Under this project, e-learning study materials were created based on themes that are common in technical practice and at the same time interesting, necessary and useful for educating students at FME. This entire project was divided into 10 basic design areas, which all contain one or more design projects. Individual design projects were worked on by academics in cooperation with students, and also with help from industry practitioners, so that everything corresponds with modern norms and standards currently used in real industrial companies. E-learning materials were created for all the design projects. These materials have been implemented into the teaching of several subjects, not only in DMD for which they were originally intended, but due to the extensiveness of these materials they are also used for teaching in other departments at FME. All e-learning materials consist of several important parts, including a 3-dimensional (3D) computer-aided design (CAD) model, calculation, drawings, technical description, etc. All these parts are necessary for describing the structure of a machine or device in detail and for explaining all their features and functions. After completing the project and implementing the new e-learning materials into teaching, it was necessary to evaluate the success of the project and its impact on the quality and methods of teaching. Questionnaires were created and given to students for completion. We were also interested in the opinions of practitioners from the engineering industry, so we asked employees of companies we cooperate with to evaluate the study materials. Using all the gathered information and opinions, we evaluated the quality of the materials and its impact on teaching. Mistakes were corrected and the whole project was brought to a successful conclusion.
