Knowledge sharing practices in post-secondary settings create pathways for better academic achievements, improved communication skills and interpersonal skills, as well as facilitate an appreciation for understanding different perspectives. Crowdsourcing has long been a part of education with students teaching one another through open-idea generation and information sharing. With discussion of knowledge sharing and crowdsourcing practices of college students centering on unethical behaviors, ethical models utilizing crowdsourcing-for-education practices with the goal of supporting teaching and learning are needed. This study proposes a model of crowdsourcing class notes using a flexible and open access system called The Flexible System for Crowdsourcing Class Notes. Implementing a system of knowledge sharing through crowdsourcing for education in higher education courses links to the principles of the Universal Design for Learning framework while also integrating conceptual frameworks of crowdsourcing-for-education practices. Using a mixed-methods design, qualitative and quantitative data was collected in fourteen higher education courses spanning seven disciplines. Results indicate use of the system throughout a 15-week semester with an average use of 10 times per student, with noted peaks around examination time, and a general dip in usage after the campus shift to online course delivery due to the COVID-19 pandemic. Results of this study indicate positive experiences with the system with recommendations for future use as reported by both student and faculty participants. Participants noted the positive effect of learning through different perspectives therefore creating a learning synergy to support the capacity for individual expert learning. The Teaching and Learning Kaleidoscope for Expert Learning is presented as a model depicting the relationship between educator, student, and technology needed to create learning synergies for expert learning.
