Open and remote labs from the UK Open University

The Open University’s remote access electron microscope set-up

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.

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.

Comments

The Open University has added a new set of quality online resources in experimental science and technology to those currently offered by, among others:

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.

The current madness in online learning: case no. 1

Goldsmiths College

Coughlan, S. (2018) University offers science degree online for £5,650 per year, BBC News, March 6

If you want to know what the very opposite of an open higher education system is, look no further than that country of privilege, class, and isolationism called England. 

This is a report of a new Bachelor of Science degree being offered fully online in the United Kingdom by one of my old alma maters, Goldsmiths College, the University of London, where I did a wonderful post-graduate certificate in education that set me up for life in teaching. The new Goldsmiths B. Sc. (actually a three-year bachelor in computer science) is deliberately targeted at part-time, working students.

Great – so far. It’s good to see a full bachelor’s degree in science being made available fully online, targeted at part-time students. 

But the mad part is that the tuition cost for this three year degree is – wait for it – £16,950 (£5,650 a year). That is roughly C$30,000, or C$10,000 a year. 

What makes it even more crazy is that this is an attempt to provide a lower cost alternative to the regular fees now being paid by students for on-campus education in England and Wales, for which tuition fees alone are around C$16,000 a year. This is because the U.K. government in 2010 cut funding for the costs of teaching in English universities, requiring the universities to recover the teaching costs through tuition fees alone. In parallel, part-time students were no longer eligible for government-backed student loans.

And why, you may ask, is the University of London offering this fully online B.Sc. when the U.K’s Open University has been offering at least a distance one since 1971? (And a full science degree at that, covering all the basic sciences.)  

As a result of government policy, the UK Open University has had to triple its tuition fees over this period, to roughly – wait for it – £17,184 for its full three year Bachelor of Natural Sciences. What a co-incidence that Goldsmith’s fees for their new online B. Sc. are £16,950, just £200 below the OU’s! 

The government policies on tuition fees and student loans have been devastating for the UK OU, which is targeted mainly at part-time students, and which had no tuition fees when it was founded in 1971. Its numbers have fallen by 30% between 2010-11 and 2015-16. 

The latest figures from the Higher Education Statistics Agency show that part-time student numbers in England have fallen 56% since 2010, from 243,355 in 2010-11 to just 107,325 in 2015-16. In terms of economic development, this is madness in government policy. In a digital society, lifelong learning is not a luxury but a necessity, and will not just benefit the individual but the whole economy. I shudder to think of the long term implications for English prosperity in the future – even without Brexit.

Why do I feel so strongly about this? I have four grand-children living in England, but their parents, who, like me, are wealthy middle class now, are willing and just about able to support their children at university. However, in 1959 I was working full time at what would now be called a minimum wage and desperate to get any form of post-secondary education. I found out that although I was 21 and had been working for several years, because of my low salary and the low income of my parents, I was eligible for a grant from the London County Council. Not only were my fees covered, but I even got a small maintenance grant that with work in the vacations enabled me to study full time. I got a place in Sheffield University, and the rest is history. However, without that support, not only would I not have succeeded in my life, nor would my children be where they are today.

I have no problem with a minimal level of tuition fees, as in Canada, provided that there is some kind of financial support to allow those on low incomes or who are unemployed to take full advantage of post-secondary educational opportunities. But no-one should be denied the opportunity of a post-secondary education because they cannot afford it. England is more backward today than it was in 1959 in this respect, which is why I am so angry. All that blood, sweat and tears that the working class suffered during and after the Second World War – and for what?

‘It’s the rich what gets the gravy and the poor what gets the blame.’ Was it ever thus in England?

Virtual reality for midwives: an Australian example

Connolly, B. (2018) How virtual reality is transforming learning at the University of Newcastle, CIO, 8 March

This article includes a couple of nice, short videos demonstrating the use of AR and VR in a University of Newcastle nurses’ program in Australia.

The first one, below, demonstrates the use for breech positioning and placenta replacement (click image to play):

The second demonstrates a neonatal resucitation scenario when a newborn baby stops breathing.

These are very good examples of the power of AR and VR to enable students to practice and learn in a safe environment without danger to patients. The technology is accessible via mobile phones or tablets so students can practice in their own time as well as in the VR studio with an instructor.

What would be useful to know is the cost of producing such VR applications and the number of students that make use of the equipment over the length of a course – in other words, what is the return on investment, compared, with, for example, traditional video? What are the added benefits? Do learning outcomes improve? We need much more research into these questions.

 

Have we reached a tipping point in teaching science and engineering online?

A remote lab used by online physics students at Colorado Community College

This post lists several new developments in delivering science and engineering online. These developments join a list of other efforts that are listed below in the reference section that suggest we may be reaching a tipping point in teaching science and engineering online.

USA: The University of Colorado Boulder’s Master of Science in Electrical Engineering

UC Boulder is offering a Master of Science in Electrical Engineering (MS-EE), a MOOC-based online, asynchronous, on-demand graduate degree in the autumn, with additional curricula rolling out in 2018-19.

The degree will have a “modular and stackable structure”, according to the university, meaning that students can select about 30 subjects that best suit them as they move through the programme. Each of the 100 courses on offer will feature in-depth video content, reading materials and resources and assessments, and many will also “bring the laboratory experience out of the Engineering Center to students around the world” by “inviting students to apply their knowledge using hardware and software kits at home”, the university said.  

The university has already designed kits for the course on embedded systems engineering – a field in which a computer is designed and programmed to perform predefined tasks, usually with very specific requirements. For this course, students will be sent a circuit board with an embedded system that can plug into their laptop and will form the basis of assignments. The results of the tests will then either be sent automatically to the lecturers or entered manually by students. The technology also means that technical assignments can be machine-graded immediately, with students receiving instant feedback. It allows students to retake assignments as many times as they want.

The home kits will cost in the range of “tens of dollars” rather than thousands of dollars. Overall the degree will cost around US$20,000, which is half the price of the equivalent on-campus programme.

Individual courses can be taken for a single academic credit, but they can also be grouped into thematic series of 3-4 credits, stacked into standalone CU Boulder graduate certificates of 9-12 credits, or combined to earn the full 30-credit degree. Each course addresses professional skills while providing content at the same high quality as the university’s traditional on-campus master’s degrees.

CU Boulder faculty have custom designed each course. Courses feature in-depth video content, curated readings and resources, and assessments that challenge students to demonstrate their mastery of the subject area. Many courses bring the laboratory experience out of the Engineering Center to MOOC students around the world, inviting students to apply their knowledge using hardware and software kits at home. 

However, the program has still to be accredited by the Higher Learning Commission (HLC), and no information was given as to whether it will be accepted by ABET, the accreditation agency for professional engineers in the USA. This will be critical, as in the past, very few engineering programs with online components have passed this hurdle

Also the notion of MOOCs being not only open but free seems to be a thing of the past. US$20,000 for a degree may be half the cost of the on-campus course, but I suspect many potential students will want to be sure that they can get full accreditation as a professional engineer before laying out that kind of money.

Nevertheless, this is a bold venture by UC Colorado, building on its previous excellent work in offering open educational resources in science through its PhET project. Founded in 2002 by Nobel Laureate Carl Wieman (now at the University of British Columbia), the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. It will be interesting to see how much the MS-EE program draws on these resources.

Queen’s University’s online Bachelor in Mining Engineering Technology

Queen’s University’s new Bachelor of Mining Engineering Technology (BTech) program combines technical expertise with the managerial and problem-solving skills the industry needs from the next generation of mining professionals, in a flexible online learning format. The university provides a very interesting rationale for this program:

Canada’s mining industry is facing a retirement crisis that is only set to worsen over the next five to ten years. With the most experienced part of the mining workforce leaving, new opportunities will open up for the next generation of mining professionals.

This program was developed as a result of discussions between the university and the mining industry in Ontario. The web site indicates the type of position open to graduates with typical salaries.

Graduates of any Engineering Technology or Mining Engineering Technician diploma who have completed their diploma with a minimum 75% average or individuals with at least two years of study in a relevant science field are eligible to enrol. Upon successful completion of the bridging program, students enter the final two years of the four-year degree program. Each year includes a two-week field placement in Kingston and Timmins. Students receive block transfer credits for the first two years of the program.

Students can study full-time, or work full-time and study part-time. This allows students to adjust their course load at any time during the program.

However, the BTech program is unaccredited. Graduates seeking professional licensure will need to apply to write the Board Exams in mining engineering. In Ontario, the application will go to the Professional Engineers Ontario (PEO). As with applications from an accredited program, graduates would also need to write the law and ethics exam, and complete the required supervised work experience program in order to be considered for licensure.

It will be interesting to see how the two programs work out. Both ABET in the U.S. and professional engineering societies in Canada have up to now denied accreditation for any degree programs with a significant online component, a necessary first step to taking the professional exams. But the Queen’s program has been built specifically to respond to the needs of employers. I will be very interested to see how the PEO in particular responds to graduates from this program wanting licensure as professional engineers – or will the employers just ignore the professional association and hire the graduates anyway?

More online virtual labs for science and engineering

Drexel University Online has an excellent series called Virtually Inspired, which like Contact North’s Pockets of Innovation

is an ongoing research project to uncover the best of breed technology-enhanced online courses and programs indicative of the “Online Classroom of the Future.”

Online Virtual Labs for Science and Engineering showcases three examples from Chile, India and Denmark of online virtual labs that provide hands-on experiential learning.

LAB4U, Chile

The Lab4Physics mobile app enables students to use various built-in tools to measure gravity or acceleration in real-time with a built-in accelerometer. They can study speed, velocity, distance or displacement using the built-in speedometer. With the sonometer, students can study waves, amplitude, time and other physics phenomenon.

Coming soon, the Lab4Chemistry app will helps students learn spectrophotometric techniques. Students can use the built-in camera as a spectrophotometer or colorimeter to analyze samples wherever they may be. By taking pictures of droplets of different concentration and optical densities, they can create a calibration plot to measure a material’s transmission or reflection properties.

Each app has pre-designed experiments. For example, a student can swing their phone or tablet like a pendulum to learn how oscillation works.

Students and teachers alike can download the app, experiment, analyze and learn with pre-designed guided lab experiences and step-by-step instructions. For those who lack Internet access, the experiments and tools can be downloaded to use offline, even in airplane mode.

Students, teachers, and institutions from primary, secondary and tertiary institutions across Latin and South America are taking advantage of Lab4U.  Most recently Lab4U has expanded their work to Mexico and the United States.

Virtual labs of India

Virtual labs of India is an initiative of the Indian Ministry of Human Resource Development. Its objectives are:

  • to provide remote-access to labs in various disciplines of Science and Engineering. These Virtual Labs will cater to students at the undergraduate level, post graduate level as well as to research scholars

  • to enthuse students to conduct experiments by arousing their curiosity, helping them learn basic and advanced concepts through remote experimentation 

  • to provide a complete Learning Management System around the Virtual Labs where the students can avail the various tools for learning, including additional web-resources, video-lectures, animated demonstrations and self evaluation.

  • to share costly equipment and resources, which are otherwise available to limited number of users due to constraints on time and geographical distances.

Anywhere from four to twenty-five labs are offered per discipline area. These areas include Computer Science & Engineering, Electrical, Mechanical, Chemical, and Civil Engineering, Biotechnology and Biomedical engineering, and more.

Virtual Labs Simulations from Denmark

Labster is a Danish company with offices in Bali, Zurich, London, and Boston, as well as Copenhagen. 

Labster offers fully interactive advanced lab simulations based on mathematical algorithms that support open-ended investigations. They combine these with gamification elements such as an immersive 3D universe, storytelling and a scoring system which stimulates students’ natural curiosity and highlights the connection between science and the real world. All that is needed is a computer or laptop and a browser to perform advanced experiments and achieve core science learning outcomes. 

Labster currently has more than 60 simulations covering a wide range of topics including Parkinson’s Disease, Viral Gene Therapy, Eutrophication, Lab Safety, Animal Genetics, Tissue Engineering, and Waste Water Treatmen. Some simulations are available in virtual reality with the addition of a VR headset.

Labster is being used for on-campus teaching at many high-reputation universities, including MIT, Harvard an UC Berkeley.

Where is the tipping point for recognising online science and engineering degrees?

We now have a wide range of examples of not only online courses, but online tools that provide experiential learning and experimental situations in science and engineering fully online. When will the professional associations start recognizing that science and engineering can be taught effectively online?

It needs to be remembered that the teaching of science, and in particular the experimental method, was invented, more or less from scratch, by Thomas Huxley in the 1860s. There was so much opposition to the teaching of science by the established universities of Oxford and Cambridge that Huxley had to move to the Government School of Mines, where he began to train teachers in the experimental method. That institute eventually became Imperial College, one of the most prestigious centres of higher education in the world.

However, it is now another century and another time.

The U.K. Open University developed low cost, ingenious experimental kits in the 1970s that were mailed to students, enabling them to do experimental work at home. Today the Open University has the online OpenScienceLaboratory.

Dietmar Kennepohl at Athabasca University, who helped develop and design much of the experimental work for Athabasca University’s distance education programs in science, has written an excellent book about how to teach science online.

Students can now access and control online remote labs and equipment that do actual experiments or demonstrations in real time.

We have online simulation kits that can be downloaded, enabling students to build and test circuits, videos that demonstrate chemical reactions, and virtual reality environments that enable students to explore DNA mutations.

The only thing that stops us offering fully online, high quality science and engineering programs now is the conservatism of the professional associations, and the ignorance about the possibilities of online learning, and the fear and conservatism, of the majority of science and engineering faculty.

What I learned at Drexel University in National Distance Learning Week

A street protester in Philadelphia on election day

A street artist in Philadelphia on election day

Fear and loathing in Philadelphia

On Tuesday and Wednesday last week, I found myself in Philadelphia on U.S. Presidential Election day, and even more importantly, the day after, as the results became known. I was there, not to ‘rig’ the election, as some have rumoured, but to visit one of the leaders in online learning in the USA, Drexel University.

I’m not going to say much more about the election, except to note that as in the rest of the country, Pennsylvania was deeply split, with cities such as Philadelphia and Pittsburg voting strongly for Clinton, and suburban areas, smaller towns and rural areas voting in sufficiently large enough numbers for Trump to just about win the state and its electoral votes. So the election results have caused a certain amount of fear and loathing in Philadelphia, particularly among the university community.

Why Drexel?

Drexel University is a private, nonprofit university ranked among the top 100 universities in the USA. In 2016 it was ranked the 8th most innovative university in the USA by US News and World Report. It has about 26,000 students.

Drexel University was founded in 1891 as the Drexel Institute of Art, Science and Industry, by Philadelphia financier and philanthropist Anthony J. Drexel. The original mission of the institution was to provide educational opportunities in the “practical arts and sciences” for women and men of all backgrounds. It is famed for its co-op education program and its close links to local industry and businesses, and in the past for its acceptance and encouragement of low income students. However in recent years its focus has changed, partly driven by the perceived need to increase its ranking. Today it has very high student tuition fees and a highly selective admission process.

I was there to visit Drexel University Online (DUO), an internal division within the university that serves those students at Drexel taking online courses and programs.

Drexel Online

Drexel University has more than 7,000 online students from all 50 states and more than 20 countries. It offers 140 fully accredited master’s degrees, bachelor’s degrees and certificate programs in a wide range of disciplines. Nursing in particular has a very strong set of online programs. Drexel was an early pioneer of online learning, offering its first fully online master’s degree in 1996.

Drexel University founded National Distance Learning Week, in conjunction with the United States Distance Learning Association, in 2007, and has won several national awards for institution-wide excellence in online education.

As part of Drexel’s contribution to National Distance Learning Week, I was invited as a guest speaker, to talk about ’21st century knowledge and online learning: re-designing teaching for a digital age.’ While at Drexel, I also took the opportunity to see what Drexel is doing with advanced learning technologies.

Advanced use of technologies at Drexel Online

DUO offers faculty a technology lending library, where faculty can try out new devices and evaluate their potential for teaching. This includes an augmented reality headset that combines a cheap ($10-$15), easily assembled cardboard frame into which a mobile phone can be inserted in front of the eyes, enabling augmented reality programs to be delivered at very low cost to the student (provided they already have a mobile phone).

DUO has also developed a very interesting web site, called VirtuallyInspired.org, which showcases a number of innovations in online learning from institutions across North America and around the world.

Here I will describe briefly just a few of Drexel’s own innovative projects, which I hope will inspire you to look in more detail at the VirtuallyInspired web site.

Tina the Avatar

Tina the Avatar

Tina the Avatar

Tina is an avatar of a 28 year old woman in a virtual world who not only responds to questions asked by students but can also be physically examined and will respond according to how she is being treated. The teaching around Tina is broken down into 10 modules, each of which correlate with a body system that students learn about in class. The program serves not only as reinforcement for the principles taught in the course, but also to develop interpersonal skills needed by clinical professionals. Professors are able to view the type of questions asked by the student and how the student reacts to Tina’s responses. They are then able to give the student advice and make recommendations for interpersonal skill improvement.

Synchronous online teaching

Drexel is experimenting with the use of low-cost (US$450) robots (Kubi) combined with iPads to improve the ‘telepresence’ of students in online webinars. In the classroom where the instructor is located, there is an iPad for each remote student locked into a robot that each student can remotely move around the instructor’s classroom. Using Skype and the camera on the student’s computer, the student’s face appears on the iPad. In this way the instructor can see the faces and hear each individual student via the iPad, and the students at home can also see on their screen not only the instructor but also the iPad images of all the other students in the class. This system is already in use at the Michigan State University.

Forensic investigation

Students taking a course on forensic investigation can use a branching video sequence to search for clues at a crime scene. Students can do a virtual walk around and inside a house and are asked to observe and interpret what they see, followed by a debriefing afterwards.

These are just a few of the several innovations that Drexel is experimenting with. Others include the use of video simulations in law and nursing, dealing with critical incidents in practice.

Innovation and operations

Drexel University is to be congratulated for two reasons: it has an extensive, ongoing online program that delivers a wide range of courses on a daily basis to over 7,000 students. For most of these courses, the challenges are common to all online post-secondary programs: ensuring that the programs are of high quality and that students succeed. This means applying well known best practices and procedures, using standard tools such as a learning management system, and ensuring that students are well supported by instructors.

At the same time, DUO is investing some of its energy and resources to investigating new ways of designing and delivering online teaching. This means finding like-minded faculty partners who can see the potential of new technologies and who are willing to put in the time and effort to do something different. The challenge here is to evaluate each innovation, to integrate such innovations into regular teaching, and then to ensure the diffusion of successful innovations into a wider range of courses and programs.

Getting the right balance between on-going operations and innovation is a challenge but one that Drexel Online seems more than able to handle.

And lastly, I cannot express enough my appreciation for the kindness and attention paid to me by Susan Aldridge, the Director of DUO, and all her staff during my visit. Elections may come and go, but American hospitality continues for ever.
