Durham field tests

The ERA team has just returned from a week-long field trip in the North East of England, based at Durham University.  We did tests at locations related to OU Geology module SXR369 along the Northumberland coastline.  We trialled new (to us) VoIP services including 2-way video with a view to assisting students with limited mobility to experience geological fieldwork alongside their more mobile peers.  Expect to see some news and test results here in the next few days.

The curse of ERA strikes again! (sunshine :-) )

The curse of ERA – bringing sunny weather to field trips – strikes again! Despite packing gaiters, gortex, and waterproof sample bags to protect our kit, it was the sunshine rather than the rain that was the challenging weather for the Durham area field trips.

Jokes aside, we’ve had great weather, mainly sunny with the occasional light smattering of rain. This is actually a significant factor for us when we’re working in the field. The radio signal isn’t affected by rain to any great degree, we’re fairly confident that students will dive for cover before the radio signal deteriorates too far in rainy conditions, but we have to watch out for sun and rain when it comes to using the equipment in the field.

We’re aiming to use off-the-shelf, consumer equipment as much as possible so as to come up with a solution that could be taken up by the greatest number of other educational institutions. There is heavily ruggedised military-specification equipment for most of what we’re doing but the cost and weight factors puts this out of our league and probably would make the ERA system much less likely to be adopted by a broad community of users.

Thursday: Configuration and Demonstration

Today we had a morning checking over kit, and trying out further configurations. One of the benefits of working alongside an Open University residential school is that we’re getting to visit a lot of authentic field sites and trying out different configurations in quite an intense schedule. So this morning we dedicated some time to documenting where we’d got to and trying some new configurations.

Another great aspect of the residential school is that we get to spend some time with tutors and students and are offered valuable insights into what their learning and teaching goals are. This year, two of the tutors (Bob and Di) working with the Additional Requirements students have kindly agreed to try out the system with a selection of their students on Friday. So the afternoon is spent setting up and running a small demonstration with Bob and Di to show them what we’re doing and getting their feedback, ready for a live test with some of their students at the Howick field site tomorrow.

Things seem to go pretty well and Bob and Di gave us some great feedback and thoughts on how they teach, what messages they are trying to get across, and how they found using the kit.

Clifftop multi-hop: Scremerston

Today’s visit brought us to the dramatic coastal features of Scremerston, just south of Berwick-upon-Tweed. This is a tough location for Assisted Requirements students as the high, steep cliff face can be quite challenging to negotiate for anyone. The closest practical access is down a gravelled lane (which could be driven up at a push), stopping before the gate to a muddy field full of cows. From there, the beach site (which should be visited on a falling tide) is accessed down a grassy cliff face 300m or so from the gate. From the beach access, the geological study site is quite stretched out along the sea front, with features jutting out from the cliff base into the sea.
