This paper provides an experience report on a co-design approach with teachers to co-create learning analytics-based technology to support problem-based learning in middle school science classrooms. We have mapped out a workflow for such applications and developed design narratives to investigate the implementation, modifications and temporal roles of the participants in the design process. Our results provide precedent knowledge on co-designing with experienced and novice teachers and co-constructing actionable insight that can help teachers engage more effectively with their students' learning and problem-solving processes during classroom PBL implementations.
