LRNT 692 Choosing stakeholders/participants for my DLRCP

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)?

The Sub-Questions:

  1. In what ways might repetitive practice opportunities contribute to OSCE success?
  2. 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.

  1. Hi Shelley,

    Thanks for sharing. I feel the same with regard to choosing the participants, for sure. Just because we select someone doesn’t mean that they may be willing or available, and I wasn’t really sure when to reach out initially. It sounds like it’ll be further down the line for me since I’m hoping for feedback on the quality assessment tool I aim to create, so that will need to be “completed” (at least in draft form) first for participants to be able to review. Again, whether or not the selected participants might have time or willingness to help at that point is just another limitation, I guess.

    With regard to selecting participants, I really like the purposive definition; I’m approaching it similarly, selecting those with specific expertise in a particular area. For that, I’m using feedback from our advisors, as well as the literature review, to help narrow that down. That said, I do find myself wondering how I can ensure that other voices are heard, for example with regard to accessibility, as well as Indigenous perspectives. These are areas that I have limited knowledge/experience, and are directly applicable in my field, so that’s something I’ll be looking for as I continue into the project.

    Not sure if any of this helps at all. Looking forward to seeing how this progresses. 😊
