In 2019, a new curriculum was implemented in the Engineering School of Universidad ORT Uruguay. Computer Science 1 (CS1, 1st semester) and Computer Science 2 (CS2, 2nd semester) were modified in pedagogy and curricula. CS1 and CS2 were traditionally presented in a traditional lecture format and both used Object-Oriented Programming (OOP) with Java as programming language. In the new approach, we implemented the flipped classroom: the student before each class reviews some materials and in class, takes place activities and discussions guided by the teacher. The new content of CS1 is aimed at developing computational thinking and basic programming skills, with JavaScript as the programming language. CS2 focuses on OOP, and more advanced algorithms with Java. The first edition of the CS1 course was completed in July 2019 and showed similar approval results of previous courses. High motivation and engagement of both students and teachers with the new proposal were detected. In this work, the results of the implementation of the CS2 course (second semester of 2019) of the same cohort are presented. Approval results obtained were similar to those of previous CS2 courses, showing also high motivation and commitment. Compliance with the flipped format that was used throughout the year was maintained. Considering that the evaluation has similar difficulties and is thematically equivalent to the previous CS2 course, it is important to notice that with the new plan and flipped approach, at the end of the 2nd semester, students manage two languages (instead of only one) and more programming paradigms.
