I debated wearing a Halloween costume to work today and decided I should because the world needs more whimsy. I was a dumpster fire (reusing last year’s costume), with a crocheted flame headband and a (fabric) dumpster cover flap draped over a shoulder. On my way to class someone else in a costume saw me and said “Oh good, I’m not the only one”

Solidarity to everyone who has a sense of whimsy and dares to be a little weird

That I took as given. I mean who (among users of screen readers) is the audience

Students? At what level?
Subject experts?
Non-scientists?

Students asked to interpret chemical structures will need very different things than expert chemists who need to pay attention to a changing functional group or steric effect, and non-scientists will probably fine with just "caffeine molecule"

Accessible to whom, for what purpose?

"A picture is worth a thousand words" in part because the same picture can be used in different contexts. Sometimes the alt-text ought to say caffeine, sometimes it ought to say "1,3,7-Trimethylxanthine," sometimes it needs to describe every blessed line and letter, and the difference is the context

What Bunsen burners *do* teach and what they *could* teach are different things. Handling hot things can be learned without open flames and "being safe" is much broader than using a Bunsen burner. In the mean time the instructor has to keep the room from filling with gas when the students can't get the strikers to spark, and (ime) most students don't *actually* learn about the fire triangle

My new job uses Bunsen burners in intro lab and I wish we didn't

I'm glad to see at least a sliver of justice for Robert Brooks, who was murdered by prison guards down the road from me in 2024. His family has received a settlement from the state that they plan to use in part to improve prison conditions. It won't bring him back or undo his suffering or take away their pain, but the state is taking notice. It's not enough, but it's not nothing

Someday I hope we give up cops and cages

One of my kids' schools has a new principal and the little communication we've received from them strongly suggests to me that this person has never worked in an elementary school before, nor are they likely a parent themselves

Because who in their right mind thinks it's okay to have an elementary school "open house" and then tell parents to leave their kids at home?! Someone has to keep an eye on the kids and open house is a good way to have kids take pride in their space. Why squander that???

Guests were encouraged to take their mug as a favor, and we brought two home. Seven years later these mugs are my go-to water glass. They are the right size for me to drink before my cold water gets too warm, they're harder to tip over than our other glasses, and the handle is, well, handy

For that matter, there ought to be better ways to deal with leftover medications

Public messaging (in the US) is individual-responsibility-oriented ("Dispose of medications properly") but there is inconsistent or nonexistent systemic support to make responsible disposal feasible. Some hospitals take old meds. Pharmacies sometimes take them, if asked. Waste disposal facilities sometimes have events to collect that kind of thing, but it's not a routine thing and it differs around the country

Lanning also had a "color diary" activity in which they took photos to notice color around them: lots of sunsets, but also artwork and photos of the human landscape (e.g. packaging in a store, light show at a concert)

They note that students were really interested in creative expression (e.g. creating artwork, one student wrote a song, another did an interpretive dance for their final project)

The classes didn't have lab sections, but they did small lab activities, and some iterations of this class were able to do field trips to the zoo to talk about animal coloration

They created a escape room activity to help the students study

Lhota made it through their talk quicker than planned so they're now doing a "bonus" topic of co-developing an AI policy with students; trying to get buy-in from students on the policy the class would use

Students (in different courses from previous part of the talk) wanted to be able to use AI for proofreading, organizing, and getting a first round of feedback; but the students strongly felt that it was important that their work have their own words

Lhota was outlining the initial design of the course as I arrived, so I didn't really catch that, but they're now talking about some of the changes they made: removing discussion boards and increasing in-class discussion via "socratic seminars" and science cafes

Socratic seminars: students prepared to discuss a topic, had an in-class discussion (possibly within groups?), then wrote a reflection; helpful but hard to grade equitably

Science cafes involved short presentations

I have joined the afternoon session late because my first choice wouldn't load the livestream, but luckily there are many wonderful options to pick from, so I am now getting up to speed with a talk from Red Lhota (Chicago State U) on restructuring a Gen Ed chem course with collaboration with students

Lhota is the first speaker I've see wearing a mask, so kudos for that from a fellow masker

Bradley Fahlman (Central Michigan U) is talking about the challenges of Gen Ed Chem: many students come in intimidated by chem, this one course could be their entire experience in chem

Their class is small (20-25) and mostly elementary ed majors; it meets 2x weekly with lab sessions some weeks during the same time (not an additional meeting)

Fahlman uses the "context-first" approach and is editor of the Chemistry in Context text

The lab activity came about because they were waiting for enzymes to arrive and needed a filler activity

They found a place to do the baking by asking the church across the street to borrow their kitchen. "If you're on a campus in the Midwest, there's always a church across the street" got some laughs

Q about siloing of chemistry vs humanities and the "why/when am I going to need this?" question

I'm struck how the replies so far have been about bridging chem from the humanities, rather than the other way around (i.e. why does chemistry matter to a humanities student, instead of why do the humanities matter to a science student)

Mention of conversion errors helpful for teaching relevance: Gimli Glider, Mars Climate Orbiter, Tokyo Disney roller coaster
