Exploring the Potential of 3D-printing in Biological Education: A Review of the Literature.

Science education is most effective when it provides authentic experiences that reflect professional practices and approaches that address issues relevant to students' lives and communities. Such educational experiences are becoming increasingly interdisciplinary and can be enhanced using digital fabrication. Digital fabrication is the process of designing objects for the purpose of fabricating with machinery such as 3D-printers, laser cutters, and Computer Numerical Control (CNC) machines. Historically, these types of tools have been exceptionally costly and difficult to access; however, recent advancements in technological design have been accompanied by decreasing prices. In this review, we first establish the historical and theoretical foundations that support the use of digital fabrication as a pedagogical strategy to enhance learning. We specifically chose to focus attention on 3D-printing because this type of technology is becoming increasingly advanced, affordable, and widely available. We systematically reviewed the last 20 years of literature that characterized the use of 3D-printing in biological education, only finding a total of 13 articles that attempted to investigate the benefits for student learning. While the pedagogical value of student-driven creation is strongly supported by educational literature, it was challenging to make broad claims about student learning in relation to using or creating 3D-printed models in the context of biological education. Additional studies are needed to systematically investigate the impact of student-driven creation at the intersection of biology and engineering or computer science education.
