Co-teaching at universities encourages student participation, opens chances for feedback, and promotes critical thinking. Co-teaching is a model that involves two or more professionals working together to plan, instruct, and monitor progress of a heterogenous or blended group of students in and outside the classroom, to achieve learning objectives. The authorslecturers in teacher education at a university of technologyembarked on PALAR (participatory action learning action research) in planning, instruction, and assessment, by working together as team partners in a process that stretched over more than two years. In this chapter we reflect on our collaboration. The process involved continuous action learning through experience, enhanced by co-reflection and critical questioning; furthermore, we undertook intentional action research with the primary goal of improving practice through successive cycles of plan-act-evaluate-reflect, and which lead to practice modification. We found that participating, collaborating, building relationships, communicating, and trusting, and the transformational nature of PALAR, are crucial to the process of enhancing learning. The findings imply that PALAR can provide lecturers with a rich learning experience. This chapter adds to the body of knowledge by demonstrating how the PALAR approach can be used in co-teaching for teacher education.
