Biographical details

Associate Professor John O'Byrne is an astronomer in the Sydney Institute for Astronomy. His current astronomical research interests centre on the rapidly expanding field of 'Astrophotonics', but he is also active in Physics and Astronomy Education research.

He is also an experienced educator, with over 20 years experience as a university lecturer, teaching physics and astronomy and managing various aspects of the teaching enterprise. Currently he is Associate Head (Teaching & Learning) in the School of Physics, responsible for all aspects of the teaching program in Physics, and an Associate Dean in the Faculty of Science with specific responsibility for academic standards. He has also taught extensively to adults, primarily within the University’s Continuing Education Program, in astronomy courses that have included viewing nights and tours to observatories in NSW.

A/Prof. O’Byrne has been an author or consultant editor for over 20 popular science and astronomy books, notably the 'Skywatching' series. He has also been a principal author for the 'in2Physics' HSC Physics text for years 11 and 12 school students, published by Pearson Education, Australia.

He is also a long-time Secretary of the Astronomical Society of Australia (ASA), the society of professional astronomers in Australia.

Research interests

A/Prof. O’Byrne's current astronomical reseach interests are focussed onAstrophotonics' - using optical fibre devices to enhance observations of faint astronomical objects. Earlier research has centred on high resolution using ground-based optical telescopes and interferometers, specifically Adaptive Optics, Optical Stellar Interferometry (in particular the Sydney University Stellar Interferometer - SUSI), multi-band optical filters for astronomy, multi-wavelength imaging of nearby face-on spiral galaxies and measuring magnetic fields on the Sun

He is also active in Physics and Astronomy Education research, with roles in various University, ALTC and AUTC projects, as well as interests in Astronomy and Physics education groups, in particular theSydney University Physics Education Research (SUPER)group.

Education Research:

Do students understand of basic concepts in Astronomy?
The Astronomy Diagnostic Test (ADT) is a survey developed in the US for undergraduate, non-science majors taking their first astronomy course. It is intended to test students' knowledge of basic concepts of astronomy. The Southern Hemisphere version of the ADT has a small number of minor changes to words and images of the original ADT to permit its use in the southern hemisphere (see http://www.physics.usyd.edu.au/~obyrne/astro_adt.html). This project will compare the available data sets, coordinate new data acquisition at other institutions in Australia, and look at results such as the gender gap in results from the US.


Preparing students for lab
We are currently developing a new system for delivering Junior Physics lab pre-work on-line in the eLearning system – aiming to improve the usefulness of the pre-work for students. The emphasis is on improving student understanding of physics concepts, experimental tools and analysis techniques. This project will use surveys of staff and student attitudes, interviews and other tools to study the effectiveness of this new system.


Gently flipping the lectures
For two years we have been trialling pre-lecture quizzes that ask students to prepare for lectures. Does it work? Do they like it? Does it make a difference? We have surveyed students to see if this gentle ‘flipping’ of the responsibility for studying lecture content works. This project will extend this work to see how best to ‘flip’ much more and get students to seriously prepare for lectures.
