Many students come into the field of computer science with many misconceptions of what computer science is about. The goal of this project is to give the students meaningful and engaging results for every basic concept that they learn in the introduction to programming course (CS1). We are developing laboratory experiences where we provide almost complete libraries and source code that the students are intended to solve and complete with some new programming concept that they have recently learned in the course. We want the students to learn that computer science is a highly applicable field, and ensure that they will get actively engaged in the CS1 course.Departamento de Ciencias de Cómputos-UPRRP
