The supernova story and research-based education
30 June 2014
Dr Steve Fossey reveals what he learned about research-based education from the supernova discovery
When the topic of research-based education comes up at UCL, one example gets mentioned more than any other.
On 21 January, Dr Steve Fossey, UCL Physics and Astronomy, took a group of students to UCL’s observatory in Mill Hill to practise using its telescopes. He’d been making similar observations from the north-west London facility since 2008 when he launched ExoCafe – an extracurricular project that introduced students to astronomical research on extrasolar planets. This particular observation, however, would make history.
The group had pointed the telescope at galaxy Messier 82 and noticed what, at first, appeared to be a new star. After making the necessary measurements they confirmed it was in fact a supernova – an exploding star marked by a bright point of light that had taken 12 million years to reach us.
The story quickly gathered pace and soon Dr Steve Fossey and his charges were posing for press shots and appearing in the national media. Since then, the supernova discovery has regularly been held up as the gold standard of research-based education at UCL. But what does it actually tell us about the approach?
At a UCL Arena Exchange session, Dr Fossey shared his thoughts.
The light that signified the presence of a supernova in Messier 82
…can be done with students from day one
“Most students who come to study astronophysics have never looked through a telescope,” said Dr Fossey. So it was with ExoCafe – working at the observatory and teaching them that most elementary practice can become their first taste of research. Then, as their knowledge and skills develop, so can the role they play in the research process, from data-gathering to turning that information into something meaningful.
…can bring people together
Dr Fossey’s ExoCafe team contained students drawn from several undergraduate and Master’s level courses. Their sessions also required either a member of staff or post-graduate student to supervise. Working together on a research project gave students the opportunity to interact and ask questions.
…requires the right project
For ExoCafe, Dr Steve Fossey chose the observation of exoplanet transits – planets in close orbits around bright stars observable by smaller automated telescopes. It is a research interest that requires a lot of data gathering. “We had a lot of potentially interesting targets, but we needed people to collect the data,” he said.
…is in demand
Dr Fossey had no difficulties finding students keen to contribute time at the observatory for the ExoCafe project. The group began with 25 students and by 2012 had involved more than 50. After the supernova discovery by students from his first-year class, two third-year students who weren’t involved were so keen to contribute they made a special effort to obtain more advanced data. “They just wanted to do this for love of doing it,” said Dr Fossey.
“In exoplanet science, there was a strong sense other teams and individuals were looking for the same things we were,” explained Dr Fossey. “Research offers a sense of competition, which is a great motivator.”
…can reap real research results
The impact of the ExoCafe project became evident when data collected by students was published, contributing to three journal papers. The serendipitous supernova discovery and announcement triggered numerous follow-up investigations worldwide.
…makes students feel they are ‘doing’ their discipline
Dr Fossey surveyed the ExoCafe group to find out what they had gained from the experience. He saw a huge spike in the numbers of students who strongly agreed that the project had increased their awareness of the research process. Comments from the group took this idea further.
- “ExoCafe was the closest I had ever got to doing actual science.”
- “To read papers by other researchers and actually to feel a part of what they are looking for, and even feel qualified enough to criticise the validity of their findings: that’s real science.”
- “Even after a couple of months of my PhD work, I am still well ahead of my colleagues in understanding of a general research environment.”
…can work on an undergraduate degree course
The subtitle of Dr Fossey’s presentation was How I Learned to Stop Worrying and Love the Thermonuclear Stellar Bomb which Exploded my Course Planning.
“The supernova discovery happened on week two of my first-year course,” explained Dr Fossey. “By week three I thought, blow this, let’s all do the supernova. We are all going to do something with the new data and ensure every student participates.”
His class set about performing their own original research into measuring the peak brightness of the exploding star, a task that involved reflective practice and connecting with recent literature and the latest ideas from Nobel Prize-winning science on the accelerating expansion of the Universe.
“The added topicality made it feel more like front line research than anything else we did, which was really exciting,” said one student.
…enthuses teachers too
“The study of supernovae is not my expertise,” admitted Dr Fossey. “I became a learner again. It drove my desire to learn alongside the students.”
Dr Fossey said he has also gained courage as a teacher and course planner. “It’s not hard to find subject matter for research-based education, but this is challenging me to somehow open questions up and make them more open ended.”
