BLIN aims to develop a set of modules for blended learning courses in numerical analysis oriented towards students in engineering and informatics curricula of the Universities of Applied Sciences. It will bring three main benefits. Firstly, UAS increasingly offer also curricula to working students, which have difficulties in attending regular classes. BLIN reduces the share of classroom hours from 50% to 30% of the total study time. Secondly, BLIN introduces a set of innovative animations, for guiding students through the process of a complex algorithm, by visualizing simultaneously the code of the program (implemented in different programming languages), the output values at each iterative step and their graphical representation. This powerful tool will help students to understand the link between the program code and its implementation. Finally, BLIN will introduce a strong tutoring system, to help working students to stay on track.
