For more than 10 years I have been teaching ICT to future elementary teachers using Scratch. Every year it is necessary to deconstruct the idea of " using and making ". In our elementary teacher-education program, at Polytechnic of Coimbra, we engage future teachers early in their preparation to formulate ways to integrate computational thinking into their practice. I discuss this issue in the first year, which´s the ideal moment and place for students (future teachers) be exposed to the computational thinking concept. So, in this poster I will present some work that I've done with the students in the first year of elementary teachers-education and their results at the end of the semester.
