#Methods2Go: Methods to secure results in university teaching

More method ideas from E.-M. Schumacher’s “Methoden to go” pool of suggestions!

Today: methods to secure results.

Learning walk

I’ve been using plenty of virtual “gallery walkes” recently, where students have worked on a joint google slides document (either each on their own slide, or each group on their own slide) and we then go through those slides together. There are several ways to do this walk — either students go through the slide deck on their own or with their groups, potentially discussing things and leaving comments, or we go through all the slides together and talk about them with the large group. But obviously, something similar works really well in in-person meetings, too (and that’s where the method originally came from).

In a “learning walk” (or gallery walk), visualized key results are put up throughout a room and students walk from one to the next to recapitulate the ideas. They could be guided by a specific question (probably a good idea) or just use this as an opportunity to recap everything they learned so far.

I can imagine this really well at the end of a semester, with key graphics on display (possibly without captions) and the task to make sure that everybody can explain all of the graphics. I would then encourage students to talk to each other, or even to leave notes with key points, thus co-creating the explanations for the key graphics. I might start out with having small groups work on a first draft for each of the graphics, and then open that up for peer feedback + additional points being added throughout the duration of the learning walk.

Learning diary

In a learning diary, students document their learning process. This can happen as part of an assessment, or formative feedback, or without ever showing it to a teacher. What I like about learning diaries is the more or less continuous documentation of the learning process, and I think it’s a helpful and motivating routine to take on, and also great to make sure notes stay in one place and easily accessible.

I have used what I thought of as “lab books” (but which is basically a learning diary) for many years now, and that’s exactly how I use them: To have all my notes in one place. On talks I’ve attended, workshops I’ve joined, articles I have read, goals I have set, tasks I have worked on (sometimes I set the first double page up as a Kanban board with the columns “waiting”, “to do”, “doing”, “done”, and post small sticky notes to the respective places, and then once a month I put all the “done” notes on a page for that month, thus creating an archive of what I achieved that month. Super satisfying, because usually this stuff does not become tangible that way!).

I’m using actual paper books for this (and I don’t see that changing anytime soon — commitments made on paper make me feel a lot more committed to them than if I just type something, and also I remember my notes by where something was on a page, what pen I used, and other similar pointers), but I am sure there are plenty of virtual methods that might work just as well or even better for others.

Structural mapping technique

A teacher provides flashcards or sticky notes with key terms, students use them to map out connections on a large piece of paper. It’s as easy as it sounds, but great for students to discuss relations between terms, maybe adding others that they need to bridge “long distances” or that they think are important to include.

I like the idea of students representing structures of concepts not just by describing them with words, but by how they sort them in space. It makes discussions a lot easier because miscommunication becomes more obvious when there are physical representation of a shared (or not) understanding.

Glossary

Throughout the semester, difficult and/or technical terms are collected and explanations for those terms are written in a shared document, either by individual students taking turns, by small groups, or by the whole class. Those terms and corresponding explanations are collected and distributed to everybody to use as glossary in preparation for the exam, or just for future reference. Love this as a co-created product of shared understanding!

That’s it for today! We’ll continue next #TeachingTuesday with “methods to end a lesson with”.

#Methods2Go: methods to facilitate knowledge application in university teaching

Another method idea from E.-M. Schumacher’s “Methoden to go” pool of suggestions!

Today: a method to apply knowledge.

Application cards

I really like the idea behind “application cards”: the teacher writes a theory, technical term or other important keyword on one side of flashcards, students then come up with an application, a concrete example or somewhere where they would encounter this in their everyday lives, and write it on the other side.

This very basic idea of matching some theoretical construct with its concrete, experience-able manifestation is so useful and something we forget too often!

My favourite example: Hydraulic jumps! Sound horriby theoretical until you start discovering them everywhere: In rivers, you sink when doing the dishes, when washing the car…

That’s it for today! We’ll continue next #TeachingTuesday with “methods to secure results”.

Molecular diffusion at different temperatures (involving tea bags and some convection)

I thought I had posted the picture below some time in winter already, but when I recently searched for it, I couldn’t find it. So either I didn’t post it, or I didn’t post any sensible search terms with it, in any case: It’s useless. So here we go again.

Below you see two tea bags that were placed into cold (left) and hot (right) water at the same time. On the left, the tea is sinking down in streaks, while at the same time on the right everything  is completely mixed through and through, showing how molecular diffusion depends on the temperature. Which is why we usually make hot tea.

Funnily enough, as I was about to write this blog post and had the picture already open on my laptop, I felt thirsty and decided to prepare a cold brew tea, which you see in the picture below. Here again you see the tea spreading from the tea bag, but it comes out in those plumes and only slowly diffuses throughout the whole carafe.

This would of course be easier to see had I chosen a white background, but since I am still so touched that my friends showed up at the train station with a flower and a flag on Friday, and also since this is literally the spot I put the tea down after I had prepared it, you get to enjoy a view of my flower and flag!

Also that fake flower on the left makes for really interesting reflections on the carafe. Especially the top two that are joint in the middle!

Wave watching on the ferry from Kiel to Oslo!

So I took the ferry from Kiel to Oslo and obviously had to document (most of) the water I saw :-)

Usually I’m quite fond of folding bridges and of ship watching. This folding bridge and tug, however, are between me and the ferry I want to catch…

Made it to the best place onboard (well, except on the bridge, possibly…). Phew!
Had a false positive test notification this morning (mind you, not a false positive test, but a poor overworked health person checking the wrong box and me thus getting the wrong text message) and even though that was sorted out within minutes, it was quite an exhausting experience! So now I really appreciate this nice spot on deck, my new rain jacket and my rain pants even more than if it had been uneventful and smooth until now… ;)

Great spot for wake watching, and the sun is even coming out intermittently!
Bye bye, Kiel, see you soon!

Awesome #WaveWatching going on!
Also: Not a lot of water here today!

See the turbulent track of another ship (blue), both sides of its V-Shaped wake (red & green) and where the wake breaks on a sand bank.

Might be difficult to see, but that’s the pilot boat just turning away from another ship. Yep, getting windy!

#wavewatching is definitely getting more interesting! And deck pretty much empty by now. Did not think I would be wearing my awesome gloves in August @kjersti.daae but am very glad I packed them on top of my luggage right with the wooly hat & rain pants

I’m not a #meteorologist but this looks … wet!

Look at how different the upwind and downwind sides of our wake look! Downwind there is consistent breaking of “the feathers of one side of the V”, upwind only some few break, but then they break somehow more spectacularly.

How the mood has changed! But note the difference between the upwind and downwind side of the wake!

Got some sun yesterday afternoon after all!

could stare into the turbulence of the ship’s propellers forever without getting bored!

Great belt bridge

Windy morning! Love this kind of #wavewatching (only slightly scared my phone will be blown out of my hands…)

That’s some nice waves! :)

Birthday weather (not mine :))
Always worth getting up for the sunrise…

How awesome are waves in the sun? Worth risking my phone for these kinds of pictures! (Yep, I should get some kind of case & strap…)

Sorry, couldn’t vacate my breakfast spot for a better angle, but look at that pretty wake! Those wavelets don’t cease to amaze me. Maybe I should get a seagoing job?

Wake watching in Oslofjord

One last Oslo fjord pic (beautiful wake!!) before we had to go back to our cabins for a very well-organized exit!

What I never noticed before today? That when the hatch to the car decks is opened, they split the bow — down to the bulbous bow — in half and move it away to the sides. Sadly I didn’t get a picture from the side where it’s nicely visible, didn’t have a free hand…

Still windy! See the gusts of wind move over the surface? (Well, I guess they don’t move in the picture, but you know what I mean…)

Fountain with a view

Now that’s my kind of water feature! Mesmerizing!

Don’t know why sculptures so often involve naked people, but this is one instance where I think it actually works

And now I’m exhausted. Let’s see how much water I’m going to see tomorrow! :)

#Methods2Go: methods to facilitate discussion in university teaching

More method ideas from E.-M. Schumacher’s “Methoden to go” pool of suggestions!

Today: methods to discuss content.

Amplifier

The idea of using an “amplifier” is really simple: after a mini lecture, students are asked to write questions on what they just heard on a piece of paper and hand it to a “lead-learner” or “amplifier”, who then asks those questions for everybody else. This lowers the threshold of asking questions, because they become anonymous and nobody has to worry about potentially looking stupid.

On the other hand, students also don’t practice speaking up and asking questions, so it might be good to have an exit plan for this method; i.e. only use this method for the first couple of lectures until students have gotten confident with asking questions in that format and have gained confidence that they won’t be ridiculed for their questions. As a next step, you could then do something like think-pair-share (where students still have the lower threshold of not asking questions in front of a large group, and but practice first in the pair, and then when someone speaks for the pair, they are at least not only speaking for themselves. And once students have gotten good at asking questions that way, maybe they are ready to just ask questions without any extra method, only maybe a little encouragement from the teacher’s side.

Silent discussion

This method I thought was funny: A question or statement is written on a poster and students add their comments in writing, without speaking. That’s basically what we’ve been doing for the last year and a half with discussion forums online! But what’s interesting is that what people love to hate online actually might not be all bad. There are clear advantages of occasionally writing things down instead of always communicating verbally: shy students might get the opportunity to participate more easily, thoughts are documented and can be referred to more easily no matter what other thoughts were brought up later, a documentation of the whole discussion is easily available. So enjoy this positive spin on discussion forums! :)

That’s it for today! We’ll continue next #TeachingTuesday with “methods to apply knowledge”.

“Evaluating shallow water waves by observing Mach cones on the beach” — guest post by Felipe Veloso on his recent #WaveWatching article!

Super excited to share a guest post today: Felipe is writing about his recent #WaveWatching article on “Evaluating shallow water waves by observing Mach cones on the beach”. I came across this article and was going to write a summary, but how much cooler is it to hear from Felipe himself? Thank you for being here! :)

My name is Dr Felipe Veloso1 and I tremendously appreciate Dr Mirjam Glessmer invitation to write this post and letting me contribute to the terrific #WaveWatching collection!!

One of the spectacular things of #WaveWatching is that the observations are ubiquitous. It doesn’t matter if you live in Germany, USA, Japan or Chile. Oscillations and waves are there, whether you observe swimming pools, lakes, sea, or even a relaxing bathtub ready for you. In all cases, the water is always naturally oscillating in a comfortable dance combining up-and-down and back-and-forth movements. If you enjoy these natural phenomena like I do, invest some of your time and take a look to the wonderful #WaveWatchingWednesday and #KitchenOceanography collections that Mirjam has gathered for us. But there are some occasions that these wave phenomena are obscured to our naked-eye observations and a more careful revision is needed to figure out where these oscillations are hidden. A turbulent river coming down of a hill, or the simple passing of fast water flow in front of our eyes are some examples of “waves hidden at first sight”. Such situation occurred to me in the latest family vacations we had as a break from the lockdowns imposed by the pandemia. In particular, this situation became the reason of an article in Physics Education, and also the reason  of why I am writing these lines.

In an attempt to run away from the contaminated air of Santiago (the Chilean capital city, surrounded by mountains), we drove ~90 minutes to Viña del Mar city, to enjoy one week in the beach side. In this place, with the appropriate weather and personal calmness, families can enjoy the waves crushing the beach, the rising of children as “sand engineers”, and the “continuous fight” between these children and the ocean waves to avoid the destruction of the sand fortresses by the water. It is in this relaxing and family-friendly environment where my story begins.

My kids are playing in the sand and my feet are partially covered by water. After long time, we are able to come out from our houses after several months of mandatory quarantines, pandemic stress, and online teaching activities. In this particular moment, watching waves looks like a perfect panorama for me. Suddenly, the voice of my daughter Pilar wakes me up and asked me two questions: “Dad, what are you looking in the water?… and dad, why does the water creates those conical shapes at the end of the undertow current?” The first answer was easy. I was #WaveWatching. But the second answer was not so simple. What about those conical shapes?

Mach cones observed in the surface of undertow water produced by stationary millimeter grains/seashells in sand. Those feet belong to my daughter Pilar and myself. Image taken from the article.

Before her question, I haven’t thought on that. Rapidly, I realized I was observing a wave phenomena in a different and non-standard way. We were observing shock waves in the shape of Mach cones!! These cones appear when an object moves inside of a fluid with a relative velocity larger than the natural oscillation velocity of the fluid. In these situations, there is a shock occurring in the fluid itself. The tip of the cone (or V-) shape arises from the relative movement of the object, whereas the radial expansion of the wave creates the sides of the cone. This explains the formation of V-shapes in the water when a ship travels in a river, or when ducks swim in the lake. In the case of beach observations, the cones were originated by stationary small seashells or larger grains buried in the sand when the undertow water current returned back to the sea with depth not sufficient to immerse my toes.

Now, I am not really sure if my 8 years-old daughter or my 11 years-old son understood completely my explanations of waves and Mach cones. But, I am sure they understood that observing nature can be a fun and relaxing activity to enjoy in family vacations. As an exercise, I taught them how to compute the wave velocity by measuring these Mach cones. I also show them that we did not need any fancy or expensive equipment to accurately evaluate it. We only require interest and fascination on looking for an explanation of a natural phenomena… a phenomena that they could observe while enjoying the beach, the sand and the family time.

#Methods2Go: university teaching methods for acquring knowledge

More method ideas from E.-M. Schumacher’s “Methoden to go” pool of suggestions!

Today: methods to acquire knowledge.

Learning-speed duo

The “learning-speed duo” method works like this: The group is split into two, and everybody in each of the two sub-group gets the same text to read (or exercise to work on) individually. When people finish the task, they (non-verbally!) signal to the teacher, who then pairs them up with someone from the other group who has finished their task, too. The two of them then explain to each other what they just read/learned/did.

I really like the idea behind this method that different learning tempos are taken care of so that fast students don’t just sit and wait for everybody else to finish. But this could potentially increase pre-existing inequalities when the “strongest” students get paired up first, and then pairs get “weaker” over time (obviously, speed is not the best indicator of “strength”, they might also be less careful). But still, it might appear to students that there is a hierarchy implied if attention is drawn to how fast they finish a task.

Also I wonder how much disturbance is introduced in the classroom when students have to physically relocate to form the new pairs, and then start discussing. So I am wondering if this method wouldn’t work much better online, when you initially have two breakout rooms (or even just assign two different tasks to everybody in your main room) and when students DM the instructor that they have finished the task, they are sent into breakout rooms with a partner who worked on the other task. As an instructor, you would need to coordinate this carefully, but I can see that working well without too much of a disruption to people still working on the initial task, and also without drawing a lot of attention to how fast someone is working.

Sandwich

I had heard of the sandwich method to give feedback (not a fan — I very much prefer the continue-start-stop method!), but wasn’t aware of this method of the same name!

For this sandwich, the teacher presents a task and asks students to think about how that task could be solved. Student suggestions for what methods could be used or how one would start working on the task are collected. This is the bottom bun, the base of the sandwich.

The teacher then explains whatever they think needs to be explained in order to solve the task: theories, methods, ways to calculate certain things, … This is the salad, cheese or whatever other interesting stuff inside the sandwich.

Students then use this to actually do the task: this is the top of the sandwich.

What I like about this method is the suggestion of explicitly giving students room to brainstorm and discuss ways to approach and solve a task before students start working on it; making sure that everybody has the necessary background information and clues to start working on it, rather than discussing all of this after students were supposed to have solved it (when some students are demotivated already because they couldn’t do it, and others don’t need that discussion any more because they had already successfully done it).

That’s it for today! We’ll continue next #TeachingTuesday with “methods to discuss content”.

When flying turns out to not be essential for academia (after Jack & Glover, 2021)

Yesterday morning on Twitter, I saw this quote: “The sudden grounding of academics has demonstrated that air travel ‒ previously deemed a necessary part of a successful academic career and university internationalization ‒ was not in fact essential.”. This, naturally, led me directly to the original article on “Online conferencing in the midst of COVID-19: an “already existing experiment” in academic internationalization without air travel” by Jack & Glover (2021).

In the article, the authors use the “already existing experiment” — academics around the world being grounded due to covid19 — to look at what alternatives for traditionally physical conferences exist and how they compare both to the traditional physical conferences, and among each other. And their bottom line is quite clear: Even though many people felt they “had” to fly to conferences to stay competitive in academia, there are other ways than physical presence to network and lead scientific discussions than being physically present (or, and that’s my comment here, at least as long as that’s what most people do).

Both synchronous and asynchronous virtual conferences have many benefits over actual physical conferences, for example that they are a lot easier to attend: they are cheaper, reduced travel time makes it “worthwhile” to attend more events, combining them with e.g. caring responsibilities is a lot easier since they can be attended from home. This leads to academics attending more, and more diverse, events, possibly organised in regions of the world that they would otherwise not have considered for physical conferences, which means that access to conferences (and all the scientific discussions and networking benefits ascribed to them) becomes a lot more accessible. Also, for some academics, the threshold to network and enter discussions are substantially lowered when they are happening in an online format.

At the same time, they do have challenges that are different from the ones experienced at physical conferences, e.g. for synchronous conferences the different time zones of participants need to be considered. Conference sessions outside of normal working hours might conflict with other responsibilities (or sleep!), creating a different set of problems, or a distribution of attendants based on what time zones are convenient given their physical location. In any case, boundaries between work and home might become blurred, and participants might not be as engaged in the conference if they can use the time to simultaneously (and without detection) do home chores or other things. Also, screen fatigue is real and can become a problem. Lastly, virtual interactions might be experienced “as less energizing and inspiring than face-to-face interactions”.

And while this is certainly all true, I want to offer my own perspective on this last point. I am running a workshop on “taking ownership of your own mentoring” quite regularly, and have done so both before and during the pandemic. The workshop is always advertised as “something to do with networking”, and participants freely choose to participate (or not, which is when they are not part of my sample). This means that my participants are usually people that feel like they want to learn more about networking, and while during the pandemic there has been a very much increased amount of questions regarding building and maintaining networks online via social media, there are still many questions and anxieties related to how to use physical conferences in order to make new contacts and engage in discussions with new people. So this assumption that seems to be generally out in the world that conferences are the best way to build networks, needs at least be qualified to include “…when participants know how to do it”. Just last week I heard from a quite deflated participant of a recent networking event, one of the first in-person events taking place again, where this participant did not talk to anyone they didn’t already know and were wondering how they could have approached some people that they would actually really have liked to meet, but then ended up only observing from across the room. So I would argue that there is a need for opportunities to learn how to use both formats, physical and virtual conferences, to their best advantage!

As for the energizing and inspiring face-to-face meetings: I feel like that also depends on the kind of interactions happening virtually. Since May 2020, I have started working with a new group of people, many of which I did not know before and have never met in person, and some of the (virtual!) meetings I have had with them have been the most significant, energizing, inspiring meetings I have ever had. So I see a huge potential in virtual meetings that for many others doesn’t have seem to materialized in the same way.

I also see many people waiting “to get back to normal”, meaning flying around the world like before covid19, and it worries me, especially when those flights then don’t result in all the networking and discussions people were hoping for, but in frustrated academics that wish they had talked to someone that they instead only saw from across the room. Jack & Glover (2021) make a strong case of the greenhouse gas emissions that can be avoided if academic travel is scaled down (which is actually an important part of their article that I just glossed over, it seems so obvious to me that we should be flying less or not at all for exactly that reason!), and call for those in charge (like funders) to make sure that air travel isn’t incentivized, but I am expecting things to pick up substantially once travel becomes easier again, unless we make sure that people don’t feel like it will be a huge hit to their careers if they opt out of flying when their peers don’t.

I think we need to work on two things: Create spaces to help fulfil people’s networking and discussion needs in virtual settings, and equip them with the skills to actually do efficient networking and discussing when they want to do it, both in virtual or in-person settings. Of course there are many awesome initiatives out there to do both, but how do we make sure people even know about them and feel comfortable and confident using them? And how do we do it before people are back to their old flying ways and feel again like they cannot opt out of it without hurting their careers?
