On my recent visit to the UK Open University, I had the privilege of a guided tour of the Open University’s remote labs. These allow students to log on from anywhere and conduct experiments remotely. The tour was courtesy of Professor Nick Braithwaite, Associate Dean (Academic Excellence), Faculty of Science, Technology, Engineering & Mathematics.
Note that remote labs are somewhat different from simulated online experiments, where students interact by entering data or clicking and dragging on screen items. With remote labs, the equipment being operated is real, with the students actually controlling the equipment in real time as well as recording and interpreting data.
The OpenScience Laboratory
The OpenScience Laboratory is a means of conducting authentic and rigorous investigations using real data and is globally available. It is an initiative of the Open University and the Wolfson Foundation. It includes:
- Remote Experiments
- Virtual instruments and interactive screen experiments
- Online field investigations
- 3D Immersive environments
- Citizen Science
- Research and development
There are altogether more than 50 self-contained open educational resource modules in experimental science, in the OpenScience Laboratory, each taking somewhere between one to three hours of study to complete.
As an example, there is an experiment to identify what causes variation in species of heather on English moorland. It is a combination of an online video recorded on site in English moorland and guided student activities, such as taking simulated measurements and calculating and interpreting data. The video is divided in to 23 parts, showing how measurements are made in the field, how to calculate slope, water flow, and organic soil depth, and how to take simulated measurements, to test the hypothesis that different types of heather are associated with different levels of slope in moorlands. This took me a couple of hours to complete.
The OpenSTEM labs
The Open STEM Labs are part of the OpenScience Laboratory project.
The OpenSTEM Labs connect students to state-of-the-art instrumentation and equipment for practical enquiries over the internet, where distance is no barrier and where access to equipment is available 24 hours a day.
Students and teachers access the equipment via a web browser through which they can view the experiment, send real-time control commands, monitor real-time performance and download data for subsequent analysis. Using remotely accessible hardware for laboratory and exploratory studies, ranging from electronics to chemical synthesis and from microscopes to telescopes, students are able to access the various instruments and other remote controlled resources virtually anytime from anywhere with an internet connection.
The new facilities are available to students studying Open University modules and may be available by subscription to other institutions of higher education.
Figure 1 below indicates the relationship between the Open Science Labs, OpenSTEM Labs and remote labs.
The Open University’s remote labs
Below are links to some of the diverse range of equipment available. Simply click on a link and this will take you to that experiment’s landing page, as seen by the OU’s students. Here you will then be able to access the equipment. Please note that you may have to book a session if all pieces of that equipment are being used by others. If you do book a session you should enter the experiment through the booking system at the allotted time. This will take you straight through to the equipment. (Not all these are currently operational at any one time and you may need to register first to get access).
The OU also has scanning electron microscopes, an auto-titrator, and a radio telescope available on request from those with direct experience of these curriculum areas. Please email OpenSTEM to arrange access and further briefing.
Many of the remote lab experiments are part of the Open University’s MSc in Space Science and Technology. This includes student remote control of a model ‘Mars Rover’ operated in a mock-up of the surface of Mars.
The Open University has added a new set of quality online resources in experimental science and technology to those currently offered by, among others:
- the University of Colorado at Boulder’s phET interactive simulations
- Colorado Community College’s remote science labs
- UBC’s Virtual Soil Sciences Learning Resources
- Athabasca University’s home lab kits (although these are available only to AU students)
- OER Commons
- MERLOT Science and Technology
I would welcome suggestions for other sources for high quality OER in experimental science and technology..
However, many more are still needed. We are still a long way from being able to build an entire high quality experimental science or technology curriculum with open educational resources. As well as increasing quantity, we need better quality resources that enable student activity and engagement, that include clearly understandable instructions, and that result in a high level of scientific inquiry. The Open University resources meet these standards, but not all other OER in this field do. Also there are issues of scalability. One needs enough students to justify the investment in software, production and equipment, especially for remote labs and quality simulations. Sharing of resources between institutions, and between departments within institutions, is therefore highly desirable.
Thus there is still a long way to go in this field, but progress is being made. If you teach science or engineering I recommend you look carefully at the Open University’s resources. It may stimulate you not only to integrate some of these resources into your own teaching, but also to create new resources for everyone.
