Remote Proctoring of the HAPS Exams

Remote proctoring of the HAPS Exams always brings up a raft of questions about the process, who does the proctoring, how you can trust the proctors, etc.

To address these questions, HAPS and ProctorU are hosting a joint webinar on Thursday, February 27 at 3:30p central time.

Hosts Wendy Riggs, president elect of HAPS, and Gabriell Darby, Director of Implementation Services for ProctorU will:

  • Outline the benefits of using live online proctoring for the HAPS exams
  • Show how easy it is for instructors to set up an exam
  • Demonstrate the student process in the ProctorU system
  • Cover what an integrity incident looks like, and how to deal with it

The HAPS Exams have experienced intense focus over the past several years.  The learning outcomes on which the exams are based have expanded from just A&P to include a stand-alone Anatomy set (and stand-alone Physiology are being constructed now). The A&P learning outcomes had a massive once-a-decade revision released in Fall 2019. Parallel work on the exams themselves, including validation efforts, have resulted in an exam program that is light years ahead of where it was even five years ago.

The back end of the exams have also been a focus for the past two years. HAPS transitioned to a new exam provider in 2019 that has substantially increased the security of the exams. The new provider also allows integrations that we were previously not available. One such integration is to allow remote proctoring through ProctorU.

Remote proctoring is a major step forward for the HAPS Exams. Now faculty can have students take the HAPS Exams before even coming to campus, online courses can use the HAPS Exams, programs with limited funding can use the HAPS Exams by having students pay directly to take the exams. A whole new world of possibilities.

 

Cleaning Anatomical Models with Denture Tablets

TeethThe weeks leading up to the start of a new semester are busy ones filled with ordering supplies, scheduling teaching assistants, and cleaning the lab. After scheduling custodial services for the big jobs and performing the little jobs, I never seem to have time to clean the models (most of which are 30+ years old!). A couple of models were so covered in grime, grease, adhesives from practicals past, ink, etc., that it was easier to put them back on the shelf and ‘deal with it later.’ In January 2018, however, I found myself with a bit of time and was finally going to clean one of our dental models that I couldn’t, in good conscience, discard without at least trying to clean it. My original plan was to use dish soap and an old toothbrush to clean it. I gave up after 30 minutes as I wasn’t making a dent in the grime. I considered other options, but the model was too big for our ultrasonic cleaner and I didn’t want to put it through a cycle in a dishwasher for fear that the force of water jets and heat would warp the model or remove paint.

SkullsAs I considered my next step, I recalled my recent dental work — two root canals, a bone graft, failed implants, and a temporary bridge. In an example of chance favoring the prepared mind, I thought: ‘I’m holding a model of teeth. It is made of plastic, a little metal, and a bit of paint — just like the bridge I soak every night. Would denture cleaning tablets work? It’s unlikely that I would damage the model by soaking it overnight and worth a try.’

After a 30-second rinse and brushing the morning after the soak, the model was like new. The difference was so striking I felt I had performed a magic trick. I immediately set out to clean another model to convince myself that this was repeatable. I use a basic methodology of 1 denture-cleaning tablet per 250ml of water (approximate) and an overnight soak. Models are rinsed the next day and gently scrubbed with a soft sponge. Paint that is not heat-set can be rubbed off if you scrub too vigorously. An old toothbrush can be helpful for hard-to-reach places.

Why does it work?

Denture cleaning tablets are primarily composed of sodium bicarbonate (i.e., baking soda — a mild alkali which functions as a degreaser), an oxidizer, and a scent (typically mint). I have been testing the use of baking soda and hydrogen peroxide as soaking and cleaning agents with similar results and have been considering OxiCleanTM (composed of sodium percarbonate (i.e., sodium carbonate and hydrogen peroxide), soda ash, and detergents) as a cleanser. Costs for denture cleaning tablets, baking soda and hydrogen peroxide, and OxiCleanTM are minimal and can ‘pay for themselves’ by extending the working life of your models. Limitations are the size of soaking containers and rinsing facilities.

CaveatsFootBones

  • Perform a small-model test case before working with larger models or several models at once.
  • I do not recommend using this technique on models made of plaster.
  • Examine models for any puncture holes (for screws, hooks, etc.) and position models during soaking to avoid waterlogging.
