My main research question is in what ways might the digital learning environment (DLE) be used to prepare pre-licensed medical radiography technology (MRT) students for success on an objective structured clinical evaluation (OSCE)?
- In what ways might repetitive practice opportunities contribute to OSCE success?
- How might an online activity designed as an open educational resource (OER) contribute to the OSCE process?
How am I going to choose stakeholders to consult with? This project limits the number to 6-10 participant, so I do not have to determine a sample size. I will need to recruit participants that have knowledge that will be helpful to me in building a prototype of my digital project. For this, I will use purposive sampling.
Purposive (or purposeful/judgement) sampling is a non-probability (not random) selection method used in qualitative research where participants are deliberately chosen by the researcher based on their area of expertise related to the research question (Campbell et al., 2020; Robinson, 2014; Schreier,2018). In my case, I will be selecting participants based on areas of knowledge including expertise/experience in OSCE use, (hopefully including faculty and past students), simulation design and OER or digital educational technology. There are several subsets of purposive sampling based on whether specific participants will be chosen in advance or if participants will be chosen over the course of the study such as in snowball sampling (Schreier, 2018). I am hoping to have participants selected in advance of beginning interviews with the help of my sponsor and advisor however, there is a possibility that a participant may recommend someone else to consult as I undertake interviews. Purposive sampling is appropriate as the participants will be selected based on their expertise and will provide valuable data to add to this research.
