CATL Observation # 6: EOSC 220 Final Lecture
No matter how experienced you are, how much time you have spent working in the field, or how long you have been studying as a student, it is still an extremely rare opportunity to be able to look at and hold literally all of Earth’s history in a single lesson. I am not talking about presenting pictures on lecture slides or timelines, I actually mean having the opportunity to touch the oldest and (~)youngest rocks or minerals on our planet (1944 AD to 4.45 Ga), with one in each hand if you so desire.
Dr James Scoates provided his 2nd-year mineralogy students with this exactly opportunity on November 30th. He constructed the class as a way to motivate his students to practice far transfer with the information and skills they obtained in his course. James started setting up the class in the hour before by putting up posters the students had created in a previous jigsaw lecture, containing each phase of mineral evolution on Earth, he put up pieces of paper around the room indicating all of the geologic time periods, and he hung two geologic timelines up at the front of the room. He also had two trolleys at the front of the room with trays of the hand specimens the students would be using during the activity.
James started the lecture by orienting the students to the room setup and revisiting the ideas of mineral evolution they worked with during the jigsaw. He did some reframing of course material for the students, most notably comparing mineral formulae to a language, calling them the ‘language of geology’. Very cool. He then continued explaining the activity for the class, showing their worksheets on the projector screen and dissecting them for the students. The students were asked to investigate one of the rocks on the trolleys (without knowing what it was), record their observations, and make some interpretations. Once the students finished, James asked them to reveal the information about their rocks, which, unbeknownst to the students, was taped inside the sample trays the whole time! It was a super elegant way to do a reveal. During the activity, James also used two computers (one for each projector in the room), and constantly used them both very effectively. For example, during the activity, he had the sheet they should be working on visible on one screen and a geologic timeline visible on the other.
Once everyone had identified their rocks and found the associated age information on the info sheets, they went to place the specimens around the room in the timeline James setup before class. James then prompted the students to go investigate the other rocks around the room and annotate a worksheet of the geologic timescale with what they learned through their investigations.
With about 10 minutes remaining in the class, James asked everyone to take a seat, and he went through a few slides summarizing their term. He did a fantastic job of showing them their journey through the course and motivating them by highlighting the skills and tasks they accomplished. He put videos of them working on different activities into the presentation, pictures of guest lectures (including my Biomineralization lecture), and highlighted some of the entertaining and well-done assignments he received, including their reports that had ‘field selfies’ on the cover. It was the most successful summary of a mineralogy course, or really any course, that I have ever seen. I learned a lot about the interesting things you can do to motivate your students to transfer what they learned in your course to the rest of their student careers and in the real world!
