A textbook on the didactic organization of teaching and learning processes attempts to live up to an ambitious claim. The latter should also be the yardstick for this publication since it addresses students at teacher training colleges, schoolteachers and trainers in industrial training departments. The author's experience in the organization of teaching and learning processes in schools (Peter Hafner) and adult education (Klaus Gotz) gave rise to their wish to summarize and evaluate this experience in a book. Obviously only the most important components of the complex didactic field can be discussed here. The aspects of didactic activity were selected with a view to readers who are interested in theoretical foundations and the realistic conveyance of didactic findings. In this sense, we see this book as an action-oriented guideline for the plaining, preparation and implementation of teaching and learning processes.

This book constitutes the proceedings of the 14th International Conference on Relational and Algebraic Methods in Computer Science, RAMiCS 2014 held in Marienstatt, Germany, in April/May 2014.
The 25 revised full papers presented were carefully selected from 37 submissions. The papers are structured in specific fields on concurrent Kleene algebras and related formalisms, reasoning about computations and programs, heterogeneous and categorical approaches, applications of relational and algebraic methods and developments related to modal logics and lattices.

This book constitutes the proceedings of the 16th International Conference on Relational and Algebraic Methods in Computer Science, RAMiCS 2017, held in Lyon, France, in May 2017. The 17 revised full papers and 2 invited papers presented together with 1 invited abstract were carefully selected from 28 submissions. Topics covered range from mathematical foundations to applications as conceptual and methodological tools in computer science and beyond.
