The purpose of the present study was to improve management accounting education through teacher initiated curriculum innovations using interventionist action research methodology. To achieve this goal, I (the teacher and researcher) designed and implemented a digital feedback system and a digital assessment system in an undergraduate finance course at a business school.The feedback system, which can be tailor-made by business teachers, automatically provide individual feedback to students working on problem-solving tasks in a spreadsheet in order to support and improve their engagement and learning. On the foundations of the former innovation, another goal with the study was to develop and implement a digital assessment system supporting teachers when grading digital assignments and examinations in management accounting subjects.The methodology utilized includes many similarities with interventionist action research (IR), which has gained a foothold in qualitative management accounting research. IR focuses on realworld problem solving and the overall goal of contributing to theory building.Keywords: teacher initiated curriculum innovations, formative feedback system, and summative assessment system 2
