Survey results are promising: Evaluators has obtained success and popularity within this group of students as a complementary tool for Compiler Construction lectures. Many students consider that it is enjoyable and useful for understanding the different aspects related to attribute grammars (i.e., semantic attributes, semantic equations, processing). Therefore, the tool’s objectives have been achieved to a great extent. It is worthwhile to point out that students find Evaluators interesting in order to realize the differences among the different types (i.e., lexical, synthesized, inherited) of attributes, although we did not anticipate this consequence when developing the tool. As a result of these positive aspects, a high number of students would recommend Evaluators to their classmates.
