Design of a programming course for teachers supporting flexible learning trajectories

How to design an online flexible learning trajectory course where students are in-service teachers with varied level of programming knowledge, interests, and different application need? This paper presents the design of such a course for teachers on applied programming. The main learning objective of the course is to provide in-service teachers with insight into how programming can be used to create digital solutions. The course is practically directed and emphasizes programming as a constructive and creative tool. The course is aimed at teachers in secondary schools. The paper describes the main design choices of the course. Based on the experience with the course, the paper reflects on the challenges to design courses that do not support a single learning path for all the students, but rather aims at providing a context where students can identify and follow the learning path that is best fitting for their competencies, interests, and needs of the local practices.
