How local field laboratories can enhance student learning – first thoughts

One of iEarth’s stated goals is to develop “local field laboratories” at at least three out of its four member institutions: UiB, UiO, UiT, and UNIS. But what exactly a “local field laboratory” is, and why it actually should enhance learning, is yet to be figured out. In a discussion with iEarth colleagues yesterday, we talked about many benefits of local field laboratories (a term which, again, isn’t clearly defined yet). I am elegantly skipping over the step 1 of the action plan, which would be to do a comprehensive literature search on the topic, and am just documenting my own thoughts after that meeting.

Let’s start out from what we know is necessary for intrinsic motivation, and hence for student learning, namely continuously feeling autonomy, competence, and relatedness (Ryan & Deci, 2000). How can we use interdisciplinary, local field sites to create conditions in which those are experienced?

— Note: ultimately, whether or not those conditions are created will of course depend on how a course is designed and conducted much more than on where it happens! —

Fostering a feeling of autonomy

A feeling of autonomy means that students feel that they have (some) choice over what they do when and where. This can mean many things, of course, and a couple of ideas are provided here.

How a local field laboratory can help foster a feeling of autonomy

Autonomous access: If the local field laboratory is close to campus, students can access (and leave!) it by themselves, possibly by foot, bike, car, public transport, rather than for example a plane. This means they can – at least to a degree – adapt it to their needs: arrive a bit earlier or leave a bit later. It also means that if that they really want to leave a situation they are not comfortable in, they can do that at any time (and are not stuck in some remote location with whoever makes them uncomfortable).

Depending on the setup, it might be possible to access the local field laboratory outside of normal hours, for example for students to catch up on experiments that they missed because of sickness, or to do extra projects because they are curious. This also gives a lot of flexibility to accommodate students that cannot be present during scheduled times.

Low psychological threshold: Field trips – especially the first one to a new location or with a new group – can be scary situations. If the local field laboratory is located close to campus, students stay in an environment where they are familiar with the general culture, language, … This likely means that they feel more confident, and thus more autonomous, in that setting.

Low financial burden: In a local field laboratory close to campus, students are likely to already have appropriate personal equipment (for example a rain jacket appropriate for local climate) rather than having to purchase it for a new-to-student-and-never-to-be-visited-again location. This lowers one potential threshold for participation, giving the students autonomy.

Accessibility: A local field laboratory close to campus is more accessible than having to hike and carry equipment in difficult conditions. A local field laboratory close to campus is NOT accessible to everyone just by virtue of its location though, but it might be easier to make it such.

How using the same local field laboratory with many different disciplines and courses can help foster a feeling of autonomy

More choice of potential research questions: If the local field laboratory is used by many different disciplines or courses, there will be more equipment available for experiments, and more diverse data from previous experiments (if there is a good data storage system). This makes the potential student research questions more interesting and provides a wider choice (if the teachers are flexible enough to allow it).

Accessibility: As stated above, accessibility does not happen by itself, but needs to be considered and planned for. But if there are many students using the same local field laboratory, there might be more resources invested into making sure that the local field laboratory is actually accessible for everybody, and also teachers can build on other teacher’s experiences and good ideas.

Fostering a feeling of competence

Feeling competent means receiving positive feedback: Either external through teachers, friends, family, or an audience on social media, or just by succeeding at doing something.

How a local field laboratory can help fostering a feeling of competence

Transfer: Learning is always situated in a specific context, and the transfer to other contexts is not easy. If the local field laboratory is located close to campus, students can transfer more easily into their own life as it is the same type of environment they spend their whole lives in, thus re-prompting the topic they learned at in that environment over and over again, making them see the world around them with the eyes of an expert – an experience of competence!

Not only one-off: Since the local field laboratory is so close to campus, students can revisit the lab if they want and either repeat or do more. They can also bring friends and/or family to show what they have learned, and have their expert status confirmed. More training in being in the lab and talking about lab content is always practising both lab and science communication skills.

A local field laboratory close to campus can also be used as a red thread throughout the curriculum: the lab can be visited repeatedly over several courses, each time going into more depth, building more competence.

How using the same local field laboratory with many different disciplines and courses can help fostering a feeling of competence

Relevance & context: In a local field laboratory that is used by other courses and disciplines, students can more easily recognise how their own discipline fits into and contributes to a larger scientific context.

Interdisciplinarity: If the local field laboratory is used as a red thread throughout the curriculum, different aspects of the same site can be explored over several courses (geology, soil, climate, weather, plants, …)), thus building interdisciplinary aspects over time, increasing competence by exploring different facets of the same site.

Fostering a feeling of relatedness

Relatedness is the feeling of being part of a supportive group. That doesn’t mean the group has to be around someone all the time, but they have to know that it is there.

How a local field laboratory can help fostering a feeling of relatedness

Contribution to local community: If the local field laboratory is located close to campus, it is also located in the community where students live. Their research can thus have a direct relevance for their community, which can help them feel more connected both by doing something for the community as well as by sharing their learning with members of that community and getting their feedback.

Reducing the carbon footprint: Doing the slightly less exciting field lab that doesn’t go to an exotic location contributes to lowering our carbon footprint, which students might perceive as their personal contribution to something bigger than themselves.

How using the same local field laboratory with many different disciplines and courses can help fostering a feeling of relatedness

Larger context: If the local field laboratory is set up well, there is an overarching theme of all the measurements that are being taken, so that everybody is contributing to something beyond just doing their laboratory results, but much bigger, beyond their own discipline.

Interdisciplinarity: If several courses are at the field site simultaneously, students get to meet students and staff from other disciplines (formally in course context, or informally over dinner) and build a larger scientific network for themselves.

Other considerations that might be relevant to universities

Of course optimising student learning is not the only consideration that universities have, and it would be naive to assume that it was. So here are a couple of other relevant considerations:

Benefits of local field laboratories

  • lower travel costs
  • lower risks connected with long travel or dangerous field sites that the university might have to mitigate
  • easier logistics because of shorter transport that isn’t going across borders or oceans
  • lower carbon footprint!!
  • the field laboratory can be used for outreach “in the field”, inviting people into authentic research situations

Benefits of using the same local field laboratory with many different disciplines and courses can help

  • synergies: using equipment, buildings, … for multiple purposes
  • easier logistics since everything just needs to go to one place
  • red thread in curriculum: teachers meet (formally or informally), talk more, improve coherence between courses / find more interesting interdisciplinary questions

Is that really the full story?

Of course, many of these arguments are just one side of a coin, and local field sites might be best suited to undergraduate education and less so for advanced courses. Maybe one of the learning outcomes is for students to learn about dealing with logistics in a part of the world where everything works differently from what they are used to, and where they don’t speak the language. Or some things just cannot be taught in a certain area because that process just does not happen there. But then those arguments should be made specifically, and weight against the benefits listed above. But I think it’s definitely worthwhile to consider local field laboratories as an alternative to many established field trips to far-away locations: for carbon-footprint reasons just as much as for all the reasons listed above!

What are your thoughts on local field laboratories? And what references should I start with when I finally will have the time to start reading on the topic?

Expedition learning

Last week, we ran an “expedition learning” course for 17-year olds. They were separated into several groups, working on different topics, and mine (unsurprisingly) worked on waves. You can see here what kind of stuff we observed when first testing the stretch of coastline we wanted to do our expedition to. And now you’ll get a picture dump of the actual expedition.

We started out in not-so-ideal-but-really-not-too-bad-either kind of weather, as you can read off the tracks below: It had been raining a little, but not very hard, and it had stopped by the time we got there.

img_0317

The drift lines looked quite promising.

img_0322

My group dove right into it (only figuratively, luckily, not literally). However I wasn’t quite sure if this guy knew what he was getting into?

img_0332

At this point we were still very close to the car, so I thought that it might be quite smart strategically to let them figure out here how high the waders go and what happens if the waves are higher than the waders… And the wakes of two ships  meeting up at a headland are a very good place to learn about that kind of things!

img_0337

This headland is a very good place to start observing waves in any case. Especially at the typical wind direction found here. Because then, looking back from the light house to the land, you see a large area that is sheltered where waves only build up gradually. Which is a very nice contrast to the waves arriving upwind and makes it very easy to observe differences.

img_0340

And then if you look downwind from the headland, you see waves sneaking around the headland from both sides. Those coming from the right are from the fully developed wave field that has been growing all the way down Kiel fjord, and then those coming in from the left are the ones that only started growing downwind of the little barrier shown in the picture above.

img_0341

Can you see it? Maybe easier on a panorama kind of picture?

screen-shot-2017-07-15-at-06-53-41

Of course we always like to look at the ring waves that appear when other waves hit stones…

img_0357

I didn’t foresee that wave watching would happen mostly from within the water, but the guys in my group made a good case for walking on the sand bank to actually measure the wave hight depending on the water depth (rather than just observing and estimating from dry land, as I would have done), but why not?

img_0359

Luckily, they found the shallowest part of the sand bank in exactly the same spot I would have told them to look for it based on the wave field ;-)

img_0372

Btw, a nice example of coastal dynamics right below. We had a coastal dynamics group, too, but I don’t even know if they looked at this kind of stuff, I mainly saw them taking soil samples.

img_0361

img_0387

And I know I made the same observation in the same spot last time, too, but I think it’s fascinating how the different directions of the ripples and drift lines and waves all come together.

img_0396

In any case, a nice day at the beach!

img_0385

Well, most of the time anyway.

img_0401

Luckily, we found shelter!

Those, btw, are Annika and Jeannine, who were working with a different group on coastal vegetation.

2017-07-11-13-11-42

But: New and interesting pattern on the beach once the rain was done!

img_0407

The kids spent the next two days putting all their observations on maps and preparing a presentation, and I am really happy with how it turned out. Of course there is some room for improvement still, but how boring would it be if there wasn’t? ;-) All in all I think it was a pretty successful course!

Expedition learning

In July I will be involved in teaching an “expedition learning” course for a week. It will be all about coastal protection in the Kiel region, so two colleagues and I went on a private expedition to scout out what can be explored where. This is a very picture-heavy post, be warned! It’s more a note-to-self to document the different beaches we looked at than something I expect anyone else to be interested in.

We started out in Friedrichsort, where there were nice breaking waves to be observed. My part of the course, you might have guessed it, will be on observing waves…

img_9010

In Friedrichsort there is a lighthouse on a small headland, and there are sand banks around it that make for very interesting wave fields, like for example below, where the sand bank almost seems to filter out some wavelengths.

img_9021

Looking seaward over the sandbank, we see breaking waves over the shallow part, and waves being bent around the sand bank.

img_9039

A similar thing could be seen on a tiny headland: Can you see how one and the same wave crest gets wrapped around the headland?

img_9049

See? So cool!

img_9052

Btw, you might have noticed the weather changing a lot over the last couple of pictures. It’s April, I guess… But a couple of raindrops here and there make nice tracers for the time since the last wave washing up over the beach ;-)

img_9060

Always fascinating: When you can see wave-less spots that are shielded from the wind, and then local wind waves and others that are travelling in from further away. And breaking on a sand bank…

img_9068

Also, did you see how nice the weather was for a couple of minutes every now and then? ;-)

img_9072

And here is a close-up of the waves breaking on the sand bank.

img_9073

Oh, and looking back to where we came from: That’s the lighthouse on it’s headland right there! And my two colleagues figuring out what’s wrong with the GPS they brought. Their part of the course will focus on more geological things than mine…

img_9077

But I really like this view!

img_9081

See how nice and regular the waves are that reach the beach even though the local wind field is really messy (as you see a little further offshore) and the waves have gone over the sandbank?

img_9090

Oh, and always one of my favourites: When nice and regular waves hit a stone and it sends off wave rings. Love it!

img_9094

One more, because it’s so nice!

img_9098

And here waves bending around a wave breaker thingy.

img_9101

And this is a picture that really nicely shows how if you don’t have wind, you don’t have waves. The lagoon there is sheltered so well that you can actually see the reflection of the bird sitting on the edge!

img_9107

And here we have a very nice superposition of waves coming from different directions and with different wavelengths.

img_9111

And waves coming through the “slit” between sandbanks and spreading as segments of a circle. Nice!

img_9113

Oh, and more waves breaking on the sand bank.

img_9119

After a while, we reached Falckenstein:

img_9120

Not so far away from where we started out at that lighthouse over there:

img_9129

Another interesting superposition of wave fields.

img_9131

Oh, did I mention we did a lot of walking in the sand? About 20k steps. Well, I guess that isn’t even too bad…

img_9146

Below I really liked the criss-crossing of waves. It’s actually one wave crest crossing itself after being bend by the shallowing water.

img_9151

And those waves get deformed a lot, too!

img_9168

And here we knew that it was a matter of minutes until those rain showers would be where we were…

img_9183

Luckily, this shower went over quickly, too.

img_9204

And this is the kind of stuff the other courses will be dealing with: Awesome formations in the coast!

img_9208

Ha, another weather front:

img_9214

And this is my favourite geological feature: there are interesting features in the sand/soil/stone (however you call it?) and then erosion marks, clearly made by water, right below!

img_9223

A little bit further along the coast, there are weird wave breakers and if the wind hadn’t died down, we would probably have been able to see more interesting waves than these…

img_9224

But the waves below were really cool: There were the ones that you clearly see on the picture at an angle to the coast, and then there were waves that came in perpendicular to the coast (so the wave crests were parallel to the coast) and they washed the other waves on the beach and back into the sea. I should really upload the movie…

img_9227

So those waves above caused ripples in the sand which are parallel to the water line, even though in the pictures the other wave field is a lot more visible!

img_9233

See?

img_9235

We ended up in Schilksee and had a look around the marina. Apart from the typical wind / no wind resulting in waves / no waves, we saw……

img_9241

…this! Pretty cool, huh?

img_9242

And again:

img_9243

One last look at the coast near Bülk.

img_9249

At this point, only one of us still felt like exploring every nook and cranny…

img_9252

Even though there were some pretty nice wave fields, but we could see them from our vantage point without doing an extra step ;-)

img_9253

Actually, there were a couple of cool features on the beach still. What’s up with those little bays?!

img_9255

img_9256

We ended the day with trying this very cool contraption to measure the coast with. It was actually a lot of fun!

img_9262

And you wouldn’t believe how much work it was to hold that ruler thingy in the wind!

img_9267

So yeah, that’s what we did. And how was your day in the office? :-)
