Design-based research for the development of a flexible learning environment

Students enrolled for the Bachelor of Radiography degree at the Central University of Technology Free State in Bloemfontein, South Africa, spent many weeks off campus at hospitals during workplace learning. A design-based research approach was applied to analyse an educational problem, namely that students apparently fail to apply the theory of radiation safety regulations to protect themselves and patients.

The purpose of the study was to develop authentic activities and assessment for radiation safety requirements, to provide flexible learning in a blended environment to students off campus.

The second-year radiography students of 2016 and 2017 responded off campus to the QuestionPro survey.

Authentic learning and assessment opportunities were contextualised and compiled to align with learning outcomes of the safety regulations as confirmed during a Delphi process. Flexible learning opportunities were delivered via electronic mail (email) and WhatsApp. Assessment responses from the students were received via mobile phones with a Web-based software tool, QuestionPro.

Of the 117 students, 92.3% responded to the QuestionPro survey. From the incorrect responses, learning areas that needed revision were identified, as well as the areas in the X-ray departments of the hospitals showing non-compliance with the requirements for radiation safety.

The three outcomes of this design-based research included the formulation of design principles, a designed product in the form of a Website and professional development of the researcher. The design-based research principles that were tested involved the use of knowledge in real life and measuring if students were effective performers with acquired knowledge.
