The use of teaching tools has become an alternative to complement the learning of school content. This paper provides some overview aspects of Compilation and performance analysis of the computational tools GALS, Grammophone, The Context Grammar Free Checker, Verto, and Parsing Simulator that were developed to support the compilation process and aim at assisting the learning in Compilers course. There are several known tools, but only a few were built for academic purposes and will be presented in this paper, as they were tested by students in the Compilers course in the Undergraduate course and also int the Master's course in Computer Science at a Brazilian Public University in Paraná to analyze hypotheses, to help verifying parsing examples and to exchange experiences about these Compiler tools. It was observed that the lexical and mainly syntactic analysis phases become more didactic and attractive to the students, making it easier to understand their functionalities and implementation of a compiler as a whole. GALS has shown to be a good option with a simple interface, working with lexical and syntactic analysis for more than one language (Java, C++ and Delphi). Studies of Context Free Grammars in LL(1), LR(0) and LR(1) format may be favored not only with GALS, but also with the tools Grammophone and The Context Grammar Free Checker. Verto, on the other hand, works didactically, not only on the lexical and syntactic analysis steps (the latter also with LR(1) Parser), but also on code generation. Parsing Simulator proved to be an intuitive tool and also presents an extensive collection of syntactic analysis options showing the step by step LL(1) and LR(K) analysis tables, promoting teaching-learning in Compilers.

The first year of an undergraduate major is a challenge for most students in the University of Brasilia. Of course, this challenge applies not only to them but to most first-year students at Brazilian and worldwide universities. This issue often leads the students to drop out of their majors. In this context, this paper presents the Program offered by the Department of Computer Science at the University of Brasilia to welcome new students to the major in a more friendly way. The program was carried out in its first edition in the first semester of 2020, and its methodology and lessons learned are presented. [ABSTRACT FROM AUTHOR]
