The #NGSS propose diff experiences 4 Ss n sci classrooms, a ‘practice turn’. Recognizing this, we (Hyunju Lee @LonghurstMax @tjscience Dan Coster @LisaLundgren21 ) sensed a need 4 a survey 4 Ss 2 report their experiencs. Here’s a thread👇abt it 1/n

So what’s a ‘practice turn’? Forman (2018) shared how the practice turn is a move toward emphasizing the professional activities that scientists undertake 2 refine & critique explanations about events that happen in the world #NGSS 2/n https://t.co/AYXANkzQdD
We started from National Academies of Science’s Taking Sci 2 School (2007)/Ready Set Science (2008) 4 Strands of Sci Learning mapped 2 3-D learning in the Frameworks 4 K-12 Sci Ed 2 as features of science classroom experiences we wanted 2 ask Ss abt 3/n
These 4 strands of science learning include 1) Reflecting on Scientific Knowledge 2) Generating Scientific Evidence 3) Participating Productive n Science & 4) Understanding Scientific Explanations 4/n https://t.co/Rr0xtWsZBu
Next we developed questions 4 our survey w several questions about the 4 strands of learning (see example of questions some of these strands) - trying 2 use language from NAS documents as possible/appropriat 5/n
How do we know it measures what we say it does? We used a 5 stage development process (see figure) - As part of this, we asked some #NGSS experts 2 give us feedback on early drafts of our questions and refined our q’s based on feedback 6/n
How do we know the survey is reliable? We tested it w a buncha Ss in a middle school as they completed our survey 2 describe their experiences in science classrooms (approx. 300 of them! 7th/8th graders) 7/n
After collecting the surveys from a buncha Ss, we did some analysis 2 c if the question that were supposed to measure the same thing did - While many questions did what we intended some didn’t, so we got rid of them 8/n
From this, we ended up w a survey we call Next Generation Science Classrooms that has 35 questions and that is ready 4 us & others 2 try out as a resources for learning abt how successful we r n providing Ss practice turn focused experiences envisioned n #NGSS 9/n
In the end we think the NGSC can b used n the future 2 examine opportunity 2 learn n science classrooms at the school, district, state, or national level 10/n
And, here’s a link were we shared it w our friends/colleagues earlier - DM me/us if you are in interested in a copy! 11/n https://t.co/gFi2TeYYA9
Thnxs @LisaLundgren21 (our co-author, friend, & science communicator extraordinaire) 4 this most excellent link for supporting us & others n communicating our research 2 our tweeps! 12/n👏👊✊👏 https://t.co/wGXRRN5d1D

You asked. So here are my thoughts on how osteopathic medical students should respond to the NBOME.

(thread)


Look, even before the Step 2 CS cancellation, my DMs and email were flooded with messages from osteopathic medical students who are fed up with the NBOME.

There is *real* anger toward this organization. Honestly, more than I even heard about from MD students and the NBME.

The question is, will that sentiment translate into action?

Amorphous anger on social media is easy to ignore. But if that anger gets channeled into organized efforts to facilitate change, then improvements are possible.

This much should be clear: begging the NBOME to reconsider their Level 2-PE exam is a waste of your time.

Best case scenario, you’ll get another “town hall” meeting, a handful of platitudes, and some thoughtful beard stroking before being told that they’re keeping the exam.

Instead of complaining to the NBOME, here are a few things that are more likely to bring about real change.
When the university starts sending out teaching evaluation reminders, I tell all my classes about bias in teaching evals, with links to the evidence. Here's a version of the email I send, in case anyone else wants to poach from it.

1/16


When I say "anyone": needless to say, the people who are benefitting from the bias (like me) are the ones who should helping to correct it. Men in math, this is your job! Of course, it should also be dealt with at the institutional level, not just ad hoc.
OK, on to my email:
2/16

"You may have received automated reminders about course evals this fall. I encourage you to fill the evals out. I'd be particularly grateful for written feedback about what worked for you in the class, what was difficult, & how you ultimately spent your time for this class.

3/16

However, I don't feel comfortable just sending you an email saying: "please take the time to evaluate me". I do think student evaluations of teachers can be valuable: I have made changes to my teaching style as a direct result of comments from student teaching evaluations.
4/16

But teaching evaluations have a weakness: they are not an unbiased estimator of teaching quality. There is strong evidence that teaching evals tend to favour men over women, and that teaching evals tend to favour white instructors over non-white instructors.
