I wanted to summarize the responses I received to my request for comments on the lab glove video I posted at
I received 17 responses, which is a pretty good response rate, since 169 people have viewed the video since it was posted yesterday. 12 of the responses were primarily positive, with several people noting that safety messages from fellow students are often easier for other students to engage with than those from more official sources.
Common concerns people had with the video were:
- not wearing eye protection during part of the video (we did discuss this issue and in context, my assessment was that it was necessary not to wear the goggles when the chemicals were not being used since there was no splash hazard and the chemicals were stored in the hood)
- the height of the fume hood sash while they were working at the hood was too high (this was a production issue during filming that was moderated by wearing goggles)
- there was handling of the pipettes in a way that didn"t control contamination (I didn"t notice this until chemists pointed it out)
- wearing nitrile gloves while demonstrating the impact of those gloves by the chemicals being used (an interesting chicken and egg question)
- further information on factors impacting glove protection, particularly invisible degradation could have been included (we talked through this before the video and highlighted the pieces of the topic that could fit into the time we allotted)
- mispronunciation of methylene chloride could impact the video"s credibility (I"ve had the same problem, not only with chemists, but with a variety of audiences - there"s a culture gap created by even small stylistic elements such as this)
- miscellaneous production issues (music volume, typos and speed of text slides)
A couple of respondents also pointed out two videos which could serve as good companions on this topic:
Choosing the Right Gloves from the ChemistryShack
Chemical Permeation, Breakthrough and Degradation of Laboratory Gloves from Northwestern University https://urldefense.proofpoint.com/v2/url?u=https-3A__www.youtube.com_watch-3Fv-3DZxGQoCqLjbE&d=BQIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=meWM1Buqv4IQ27AlK1OJRjcQl09S1Zta6YXKalY_Io0&m=rNa5HevKxLTGBunQP0ohakYJF_a9JP3tRLtqwmDcD4s&s=WQvoRZeFNO6uQPyX6O1XlBkRMy3HvandL3ke7iQC7Ik&e=
I don"t think that any of these concerns mean that the Keene State video is unusable; the last item is fixable. The others I will address during discussions with the class. This points out one of the challenges of any safety video or other forms of distance education - in my experience, discussions of the safety issues in such demonstrations are at least as important as the content included for learning to be effective.
Thanks to everyone who responded. I"d be interested in further discussion as people feel so moved.
