This poster presents the Coding Bazaar, a new student-centered on-site format where learners collaborate to solve challenges in a gamified and hands-on way after having learned and applied programming fundamentals through self-study. This event gives us lecturers the opportunity to meet and interact with students on an equal footing outside of the traditional classroom format.

It is a challenge to replace traditional, lecturer-centered teaching structures with learner-centered ones that adapt dynamically to different requirements. With this poster, we present our experiences in the transition from rigid instructor-centered to dynamic student-centered programming courses with large and diverse student groups and we show some statistics from our current courses.

Automatic feedback during a coding exam can be very useful for both the students and the examiners. It can provide a quick and objective evaluation of the code written by the students, which can save a lot of time for the examiners and ensure consistency in grading.

Introductory programming courses at university level often face the challenge of having to initiate learning to large student groups with a wide range of prior knowledge. We present a teaching concept that supports individual students' self-learning through online tutorials and programming project work with automated tests on one hand and regular face-to-face project discussion meetings with teaching assistants (TAs) on the other hand. In our teaching approach, TAs take on a new central role with more responsibility by coaching students individually and providing personal feedback. By individualizing and decentralizing the courses with one-to-one tutoring by TAs, they seem to be better adapted to the different needs of individual learners.
