Stealth Innovation for University Education

How do you speed up the implementation of e-learning, while maintain high educational standards? The worry was that initiatives such as Massive Open Online Courses (MOOCs) may distract from the need for universities to have staff who know how to teach and design courses. The temptation is to think you just need some web designers to customize the pre-prepared educational content purchased (or obtained free) from elsewhere.

The urge for the teacher-less university is reminiscent of the proposals for 5th generation programmer-less computing almost thirty years ago. It was thought that computer programs would write themselves, so programmers would not be needed. The reality was that easy tasks could be programed by non-programmers, but computer programmers with very advanced skills were still needed for the hard tasks. The advent of programming languages for non-programmers resulted in poorly written programs by untrained personnel. In the same way, web tools for e-learning may result in poorlydesigned online courses.

Many university academics receive little education in how to teach and have none in how to design online courses and may never have completed a formal on-line university course. How then can universities have staff who can teach in and design on-line course?

The typical university student needs to be on campus for about one quarter of their program, with the balance of their education on-line from any location. One possibility is Australian students undertaking part of their education at Australian government funded Asian universities. This form of blended learning could provide the students with a balanced education, useful in a connected world, with Australian universities producing suitable courses. Alternatively Australian universities might be reduced to agents for off-shore campuses and courses.

The future of Australian university education should be decided, in part, by the educators. Those who claim to be "professionals", in any field, have a responsibility to act in the public interest, setting standards and policies for the profession and then implementing them. As an example of this in 1995 I outlined for IT professionals how Internet policy was developed and implemented in the Australian Government ("Internet in Government - for IT Practitioners"). A process similar to this is described by Paddy Miller and Thomas Wedell-Wedellsborg  in"The Case for Stealth Innovation" (Harvard Business Review, March 2013).

Asia-Bound Study Grants

The Australian Prime Minister announced that applications were open for small grants to help students study in Asia ("Applications Open for AsiaBound Study", 6 April 2013). The "AsiaBound Grants Program 2014" opens on 8 April 2013.
The grants will be made through Australian universities and vocational education institutions who partner with an overseas institution. Amounts of up to $2,000 per vocational student and $5,000 per university student are offered. It is not clear why vocational students receive less money than university students. The grants are to "... offset some of the costs involved in participating in an international study in Asia of one or two semesters ...".

The AsiaBound Grants Program Guidelines require that the student has to study on a campus in the nominated Asian country. However, the guidelines do not say how long the student has to be there for. It is likely that most new students will be undertaking studies in blended mode, with about 75% of their time on-line and 25% in the classroom. The optimal location for the student when studying on-line, or in the classroom, may differ from course to course. The student could be physically on the Asian campus to absorb the local culture informally, while their formal study is on-line with an Australian university. Alternatively the student might be at the Asian campus for a short intensive part of the program and undertake the rest of the course on-line in Australia. Some blend of the two is likely.

The Asia-Bound Study Grants may have the unintended effect of subsidizing the outsourcing of Australian university education to lower cost Asian countries. Australian universities will be paid extra to have their students studying at partner universities in Asia for up to two semesters. So Australian universities could use a lower cost Asian partner to provide up to one third of a university degree for Australian students. The Australian students might do the rest of their degree on-line and never set foot on a campus in Australia.

In announcing the new grants, Prime Minister Julia Gillard compared them to the the Colombo plan: "What we do today dwarfs in size and scale the work that was done under the Colombo plan." This is not quite correct, as the Colombo plan was an international program for aid and did not just bring overseas students to Australia. Also the Prime Minister is incorrect in implying that Colombo Plan has ended, as a small secretariat still operates from Colombo coordinating some programs.

Audit of Learning Technologies in Government Schools

Photo of report coverThe Victorian Government conducted an audit of Learning Technologies in Government Schools. It was found that the Victorian government's policy for ICT in schools, titled the Digital Learning Statement, lacks a clear action plan and framework for investment in learning technology. As a result there is "... little guidance on how future learning technology initiatives can be appropriately planned and integrated". More positively the planning for a fibre-optic network for schools was found to have a "robust needs and options analysis". However, the software project, called "Ultranet", was "...poorly planned and implemented". The system is 80 per cent over budget, late, has a low uptake rate and limited functionality. It would seem to me that the Victorian Government should retain the network and computer hardware, but replace the software with open source, including Moodle and Mahara.

The audit report is the equivalent of 53 pages of very clear analysis of a complex social and technical issue. The report would be of value for those interested in the issues of technology for education at all levels, not just schools. The Auditor-General has published the report as a well formatted and efficient HTML web page as well as the more usual (and harder to read) PDF.

Conclusion

DEECD’s Digital Learning Statement (the Statement) does not provide a clear action plan or framework for investment in learning technologies. There is no supporting strategy or further detail to the Statement. This means that departmental staff and school leaders have little guidance on how future learning technology initiatives can be appropriately planned and integrated to build upon past and present ICT investments.
Planning for the VicSmart high-speed fibre-optic network for all government schools was underpinned by a robust needs and options analysis. Although the project was a less complex infrastructure rollout, it was well executed and is delivering its desired benefits. The high-speed connectivity that VicSmart provides is a key enabler of current and future digital learning in government schools.
In contrast, the Ultranet, the Statement’s key foundation plank and key enabler, was poorly planned and implemented. Six years after its announcement as a government priority, it is yet to achieve expected benefits for students, parents and schools. It is significantly late, more than 80 per cent over its first announced budget, has very low uptake by users, and does not have the functionality originally intended.
This audit identified a number of serious probity, procurement and financial management issues surrounding the Ultranet project. DEECD’s tender process lacked rigour and was seriously flawed. There is little confidence in the costing and financial management practices around the Ultranet project, and limited assurance that the selected outcome represented value for money.

Findings

Digital Learning Statement
The Digital Learning Statement—the government’s current policy document on the use of learning technologies—was not informed by robust and comprehensive research and does not make a clear and cogent case for government investment in learning technologies.
The Statement does not deliver on the directive in the 2008 Blueprint for Education and Early Childhood Development to provide a plan of action to use learning technologies in teaching and learning. A review of DEECD’s advice to the Minister for Education shows that the government was not advised that the Statement did not comply with the Blueprint’s directive to develop and deliver a strategy.
To date, there has been no accompanying detailed strategy developed to support the Statement, even though this was originally planned.
VicSmart high-speed broadband for schools
Planning for VicSmart was underpinned by a robust needs and options analysis, as demonstrated by its 2005 business case, which articulated the needs to be addressed and provided a clear rationale for the purchase of high-speed fibre-optic broadband connectivity. The business case provided confidence that the project was achievable and could be delivered as planned.
The VicSmart procurement process was streamlined by using a mandated whole-of-government single-source provider. The fibre-optic system is performing as expected and has been upgraded incrementally to meet emerging data and connectivity needs across the government school system.
Ultranet e-learning system
The Ultranet project was poorly planned and implemented. None of its three business cases had a well thought out needs analysis or gave considered options to deliver the project. The various business cases did not answer the ‘Why invest?’ question for the Ultranet, nor did they provide a sound basis for the project’s approval.
Some six years since its announcement as a government priority, the Ultranet has not delivered its main objectives:
  • to improve responsiveness to individual learning needs
  • to provide better information to parents, the school system and government
  • to improve the efficiency of the learning environment and school administration.
Consistent with public sector practice, the Department of Treasury and Finance (DTF) and the Department of Premier and Cabinet (DPC) provided advice to government at key decision points over the life of the Ultranet project.
The project continued despite advice from central agencies that it should cease or be delayed. Further, there is no trail of documentary evidence to explain whether or how DEECD addressed the many critical issues raised by DPC and DTF.
It is difficult to understand why the Ultranet procurement was able to proceed to contract execution, given the significant concerns raised by DPC and DTF, as well as the many adverse ratings that DEECD had received from various Gateway reviews since the project first commenced.
Further, this audit detected a number of serious process and probity issues in relation to tendering and procurement for the Ultranet. DEECD has advised that it has commenced a number of actions and further detailed investigations in response to these matters.
There is little confidence that the financial management practices relating to the Ultranet were sound and that full costs have been adequately recorded. VAGO estimates that actual capital and operating expenditure for the Ultranet was approximately $162 million as at June 2012, and by June 2013 it is likely to have cost approximately $180 million. DEECD has advised that it is currently investigating the financial practices in relation to this major ICT project.
Despite this significant expenditure, no cost-benefit analysis has been conducted to determine whether the Ultranet provides value for money, or whether the same functionality could have been delivered more cost effectively.
Performance indicators for the Ultranet have been revised down over time and do not provide appropriate measures of whether the Ultranet is achieving what the government expected when it funded the project.
Use of the Ultranet is low, and declining. On average, only 10 per cent of students and 27 per cent of teachers logged in on a monthly basis from July 2011 to May 2012.
An underlying factor which has limited the effective implementation of the Ultranet is the significant discrepancy between the original scope of the project and expected benefits and what has actually been implemented and delivered. This underscores the urgent need for DEECD to review whether it should continue to invest in this project.
Further, DEECD did not adequately manage the change processes required to maximise the Ultranet’s acceptance and, therefore, the state’s return on investment. Teachers and parents were not appropriately trained and supported to use the Ultranet. Ultimately, the Ultranet is only a technology tool, and cannot by itself deliver the benefits intended from it.

Recommendations

The Department of Education and Early Childhood Development should:
  1. develop a comprehensive and evidence‑based strategy or plan of action for use of learning technologies to underpin and guide the significant investment in ICT for government schools
  2. develop performance indicators that measure both VicSmart’s ongoing operational performance and its achievement of intended benefits
  3. urgently review its investment in the Ultranet, with a particular focus on:
    • assessing whether the contractor has delivered all functionality as required by the contract and what action, if any, needs to be taken to enforce the state’s rights
    • rigorously assessing its financial management practices and identifying the real, current cost of the Ultranet to determine the extent to which further investment is warranted
    • identifying and addressing the underlying causes of low take‑up rates across the school system by teachers, students and parents
    • providing advice to government on the cost-benefit of decommissioning the system now against continuing to fund and rectify the system so that it can be implemented as originally expected
  4. conduct an agency-wide review of its internal tendering, probity and financial management practices in light of the serious issues identified by this audit
  5. expedite the provision of guidance to schools on the current status of the Ultranet as the department’s key learning technology investment, and clarify the policy context of schools’ autonomy in purchasing non-Ultranet learning technologies. ...

MIT Free Open Learning Software

MIT has announced that it is making its MITx open learning software available free in "spring 2012". But if MIT wants to offer educational facilities on-line worldwide, it will need to adjust to a wider range of cultures. As an example "spring" is at a different time of year in the southern hemisphere.Link

Communities of practice in Indigenous communities

Curiously the term "community of practice" did not come up at the ANU Educational Research Conference, until the last session by researchers from the ANU Centre for Aboriginal Economic Policy Research. This was in Dr Inge Kral's discussion of "Multiple Pathways to Learning for Remote Indigenous Australian Youth". Dr Kral pointed out that what is measured in Australia wide standardized education tests is not very relevant to the needs of indigenous students in remote communities.

It occurs to me that use of e-learning and devices such as the OLPC would not be of use if they simply deliver the same syllabus in the same way.

Dr Kral pointed out that education continues for young people beyond school and so are invisible to education policy makers.

Dr Kral then addressed how indigenous learners made use of digital technology. A typical sight in remote communities is students with laptops, tablet computers and smart phones. The technology is not being used to just deliver a traditional course, but to provide a local identity on-line.

Dr Kral pointed out that a new definition of literacy is needed for the digital age. This involves video, audio and music. The associated learning is based on projects and informal group activities.

It occurs to me that these insights can be applied to better education for the wider community, including at university. It is also possible that just as traditional aboriginal art was successfully translated to new media and became financially and culturally successful worldwide, indigenous multimedia may similarly successful.

Marketing Student Directed On-line Learning

The University of New England is running a clever TV advertising to promote their on-line courses: "Little Boxes Distance Education". To the tune "Little Boxes".

A matrix of images of a boring urban landscape is shown. A very confident looking person then steps into the shot and pushes the various rectangles, showing them to be a wall of boxes. This then reveals an outdoor cafe, where the person sits down at a table with a laptop and mobile phone on it. The mobile phone rings and displays that the caller is "Professor Elkins, UNE". The person answers the phone using the Professor's first name and thanks them for the assignment feedback.

ps: The video appears to have been shot in a building on the corner of Pitt and Spring Streets, Sydney, not at UNE's Sydney Centre.

about the handbook

... The Handbook has two parts: Conceptual overviews and technology applications. Many textbooks, research papers and reference materials have already been written about e- learning, and this one could easily get lost in that wealth of information, but for the conscious approach taken by the Editor to involve international scholars to share their ideas and experiences that could provide diversity and richness of the philosophy, technology and practices surrounding e-learning. So, you have 25 Chapters written by 26 experienced and emerging experts in the field of e-learning, sharing with you tips for successful use of e-learning technologies. You can use this Handbook in a linear manner from Chapter one to the end or read a specific chapter depending on your interest and immediate need and relevance. Most chapters provide you practical tips, resources and references to further reading, and we encourage you to go beyond this Handbook. Apart from the references and links provided in each of the chapters, we would direct you to another publication, released by the University of Colorado, Denver (Lawenthal, et al, 2009). ...

Open Source Web Conferencing for Distance Education

Just came across "Big Blue Button" which claims to be open source web conferencing for distance education. This might be a useful alternative to Wimba Classroom and DimDim. It seems to have much the same features. I joined the demo conference and it worked okay on my low power netbook. The source code is available.

However, BigBlueButton, Wimba Classroom and DimDim all use Flash and all assume that the presenter is showing Powerpoint, PDF or similar documents. DimDim does have a limited function for sharing web pages, but does not exploit this fully. There is scope for a product which genuinely works with web pages. Perhaps this could be done with HTML5 and could be tightly integrated with Moodle. This would simplify the software needed and reduce the resources needed to use the system. Essentially the system would be reduced to a small amount of code to knit together the web, audio and text chat functions.

Digital Education Revolution Resources

The Australian Department of Education, Employment and Workplace Relations (DEEWR) has a useful list of Digital Education Revolution Resources. Unfortunately these are on a very poorly designed web page. It is a shame that this excellent work, which is costing Australian tax payers many hundreds of millions of dollars is so poorly presented. A few hours work would make the material far more accessible. The page is headed "Experience the Digital Education Revolution www.digitaleducationrevolution.gov.au". The web address is not linked to a web page and entering that web address manually ends up back on the same page on the DEEWR web site. The list of links to resources on the page do not seem to work. These are supposed to link to further down on the same page, but actually go nowhere. This is unfortunate as the education resources listed are excellent, if you can find them. Many of the materials are in the form of hard to get, hard to read, poorly formatted, large PDF files.An example of this is "Listening to Students’ and Educators’ Voices: Research Findings" which is so poorly formatted that DEEWR offer to mail a printed copy.

Leadership Training for the Australian Government

Austrade have issued a Request for Tender for "Harvard Business Publishing Online Content". Perhaps they should have made the RFT about materials for leadership and management education, not specifically the material which only one company has the rights to supply. Harvard Business Publishing supply the materials Austrade has asked for, so it is not clear how Austrade were planning to have a competitive tender process.

The contractor is required to provide Harvard ManageMentor, Essential Leader, Case in Point, Stepping Up To Management, Leadership Transitions, Harvard Business Publishing Centres, Leading for Results, Fifty Lessons, Harvard Business Review Reprints and Faculty Seminar Series. These are all good materials, but other organisations provide other similar material. In addition, Austrade might want to consider online collaborative education for their staff, rather than just passive reading of web pages.

Distance education for millions of unviersity students

Greetings from the famous room N101 at the Australian National University in Canberra, where Professor Uma Kanjilal, Director of the School of Social Sciences, Indira Gandhi Open University (IGNOU) is speaking on "Standards and distance education". The talk is being recorded and I will provide a link here, when available. The Professor is visiting Australia and will speak to federal government agencies later in the day and at University of Canberra, later in the week. The visit is funded by the Australia-India Council, University of Canberra and Flinders University and the purpose is for knowledge exchange around ICT in education. I will post some comments here as the talk goes along.

Initial distance education in India was printed material by post. Integrated multimedia is being added, with TV and radio. It needs to be kept in mind that infrastructure is needed, including libraries and A/V facilities, computers, and Internet.

India has a Distance Education Council to oversee provision of courses. This sets standards for materials, registration processes, support services for learners, ICT infrastructure and assessment. Before creating a course, the institution has to do need assessment to show there is a requirement for a course and who the target group are.

The Indian Distance Education Guidelines are available online:
  1. Norms and Standards for Management Programmes
  2. Norms and Standards for IT Education
  3. DEC-GUIDELINES, for regulating the Establishment and Operation of Open and Distance Learning (ODL) Institutions in India
  4. Norms for ODL
  5. Norms for Online Programmes
The India PM has set up a National Knowledge Commission as a high-level advisory body. There will be an advisory group on Pedological Content and a Technical Advisory Group.

India uses its own satellites for broadcasting educational material. More interactive and feedback techniques as resources permit. Few Indian students have Internet access at home, so some methods being used are cyber cafes. Mobile phone SMS is being used for student support and 3G smart phone support will be offered when these phones are more widely available.

ps: For my own experiences of Indian cyber cafes and wireless networking, see: Living in an Indian Village in Goa for Three Weeks

pps: Unfortunately the battery went flat in my MP3 recorder, so only the first 10 minutes of the talk were recorded: Uma Kanjilal ANU 2009 05 11 (MP3 4.48Mbytes)

DimDim Web Conference for E-learning

DimDim is a web conferencing product popular for education. This is because it offers a free service for conferences with up to 20 participants. It also claims to require no software download and be open source. However, it uses Adobe Flash for the audio and video, so that needs to already be installed on the computer used. I found DimDim very easy to sign up for and start a conference with. It has the usual whiteboard, desktop and presentation sharing features of such products. One interesting feature is web co-browsing, where the presenter selects a web page and it is displayed on the participants screens, scrolling synchronised with the presenter's screen.

Co-browsing works very well with HTML Slidy presentations, such as my "Learning to lower costs and carbon emissions with ICT" (slides). This could be very useful for bandwidth efficient presentations, as the Slidy slides use a lot less storage than the typical Powerpoint or OpenOffice.Org presentation. With the video frame rate turned down (or off) and the audio reduced to telephone quality, the web conference would use very little bandwidth. USQ's ICE open source e-learning content creation system produces Slidy as part of a course package, which would then work well with DimDim.

One catch is that, for security reasons, DimDim does not work with web sites which require you to enter a user-id and password. I found that this stopped access to Moodle courses, even those which allow access without a user id (I will ask DimDim to fix this). Another limitation is that the web browsing is not recorded along with the audio, video and other content.
