The distinction between Arts, Humanities, and Social Sciences on the one hand and Science, Technology, Engineering and Maths on the other will become starker because of online assessment. Although the distinction isn't absolute, it's broadly true that in the former subjects there are few questions to which the answers can easily be categorized as right or wrong (and allocated to these categories by a computer) and in the latter there are many such questions. For this reason, the two domains of intellectual work will pull away from one another regarding teaching and learning just as they already have done in other areas, such as research and the dissemination of knowledge. Arts, Humanities, and Social Sciences still rely primarily on the printed monograph for dissemination of research outcomes, while Science, Technology, Engineering and Maths use the journal article (commonly circulated digitally). In the former subjects, the academics care about ideas from long ago, while in the latter the academics care little for anything written more than a few years ago. This has considerable impact on institutions such as libraries, which in the Arts, Humanities, and Social Sciences are places where research is undertaken, while in Science, Technology, Engineering and Maths libraries are places where learning takes place. This all amounts to a fundamental rift in the idea of what a university is for, and it's part of an even wider rift in our culture's capacity to record the results of human thinking. The latest technologies are exceptionally good at enabling instant communication of the latest thinking--such as what someone on the ground in Aleppo thinks of the war there--and exceptionally poor at enabling long-term preservation of old thinking. (As the British Museum curators are apt to point out, it's much easier to preserve an Egyptian papyrus from 3,000 years ago than to preserve a floppy disk from 30 years ago.)The distinction between Arts, Humanities, and Social Sciences on the one hand and Science, Technology, Engineering and Maths on the other will become starker because of online assessment.

There is no way to be absolutely certain without seeing the person face to face. Many international students work hard to find ways to beat the system - we see it all the time. The more enterprising then sell their skills. No wonder the sign up was so high for London. Just because someone is sitting in front of a computer with iris recognition technology doesn't stop them reading from a piece of paper stuck on the wall or another person dictating from afar. Both institutions and students are heading for a fall because theses courses will soon become discredited, (some distance qualifications are not accepted in the Gulf for example) and students will end up with a worthless certificate.....There is no way to be absolutely certain without seeing the person face to face.

I teach commencing humanities students at one of Australia's new universities. There is a good story to tell here. The majority of these students apply to study with comparatively low tertiary admission scores and commence their degree courses quite unprepared for higher level learning. Many of these students are immigrants or the children of immigrants and come from homes where languages other than English are spoken most of the time. Around 22 per cent of these students come from the bottom SES quartile (compared to 16 per cent across all Australian universities). This is the changing face of higher education in Australia. Federal government policy is supporting a rapid increase in participation by students from low-SES backgrounds who are typically the 'first in the family' to attempt higher education. While attrition rates are quite high at the first year level (around 25 per cent of this humanities cohort don't continue on to the second year although many return later to try again) the majority do persist and go on to complete their degree studies. Most report high levels of satisfaction with their course and with their academic performance. The commencing humanities students are supported with foundation subjects to build academic literacy and other pedagogical strategies designed to build confidence and 'learner identity'. While some use is made of 'e-learning' or 'blended learning' approaches - welcomed by digitally literate younger students in particular - the most crucial and intensive learning in those early weeks and months on campus occurs in small face-to-face tutorials rather than in large lecture rooms or virtual forums. Students report that challenging classroom conversations - about difficult scholarly texts and controversial social issues - extend their thinking and their confidence. While Coursera and other online offerings might be playing an increasingly useful role in fueling students' passion to learn, and providing authoritative course content, I doubt that such offerin gs will easily replace the intensity and effectiveness of those Socratic situations where students and their teachers have difficult embodied conversations.I teach commencing humanities students at one of Australia's new universities.

I am currently studying the online course on edX. My take on the subject is simple, I am doing this course to increase my knowledge and go up the professional ladder. If i was to cheat around the tests, my knowledge would be incomplete and I will be found wanting during the interviews and hence cant get the job I want. This could be the sucess of hounour-code. These courses will enable people to learn new skills and bring them into the workplace.I am currently studying the online course on edX.

As a mother of a toddler with a full-time job, it is almost impossible for me to study any other way than online. I am halfway through a three-year online MSc, and the academic standards are as rigorous as those for on-site learners, but with the added complexity of limited interaction with other students and lecturers. I'm sure there are students who will cheat online, just as there are in-person learners who plagarise. Generally though, most of us studying online are more committed because we'd made the choice of this learning method because we have to.As a mother of a toddler with a full-time job, it is almost impossible for me to study any other way than online.

I am currently studying on two Harvard/MIT edX computer science/programming courses and they are very good. I have completed a number of traditional degree courses during my life and I find this course delivery system to be less stressful and more productive than typical lecture hall/seminar/tutorial teaching. It is a style of learning which is particularly well adapted to older people as it can be done at home in one's own time and at zero cost. It is, however, a solitary experience and, as such, may not be right for younger people who are looking for a more fun/social experience at university. I have signed up to the 'honor code' and if you are only interested in learning, this works fine. I can see, however, that if your sole purpose is to obtain a diploma, then it would be very easy to cheat. On a technical degree course, I can't really see how just having the diploma would help you, as you would soon be found out in the work place if you didn't know your stuff ... This is the future of education in my opinion and I think it's wonderful.I am currently studying on two Harvard/MIT edX computer science/programming courses and they are very good.

Before worrying about online students, first schools and universities round the world need to stop offline students buying their assignments and handing them in as their own work. "TurnItIn" software may stop plagiarism but it doesn't stop uniquely written essays and assignments being bought and submitted. Schools and universities currently have no mechanism to stop it, meaning most qualifications are not believable.Before worrying about online students, first schools and universities round the world need to stop offline students buying their assignments and handing them in as their own work.

We are seeing the start of the education/learning revolution. The internet and access to technology can mean that anyone can learn anything, anywhere. We are a generation away from the end of the formal 'testing' of knowledge and understanding and moving towards a true 'learning portfolio' that will record your capabilities. This transition will reduce the possibility of cheating. You can cheat a high stakes final exam, but who could maintain this for smaller, focused events that record your grasp of something specific? A 2:1 in a subject is only of value to an Employer if the parts of that subject applicable to the job are the parts you did well in.

Is there an absolute guarantee that the person sitting an exam in a campus university is who they claim to be? The problem is not confined to distance learning institutions. There have been stories of students paid [or otherwise encouraged] to sit exams under another's name for as long as there have been universities. Likewise the allegations of teachers in "certain schools" completing examinable coursework [notably in fine art] for their pupils.

I've just started studying for my BA in English Language and Literature with The Open University. I would think that anyone that signs up to do a course online wouldn't cheat as it means you're spending thousands of pounds to not learn. I think to throw yourself into a course you need to be quite dedicated. I'm a mother with a full-time job and this degree is going to take me six years to complete. I have no intention of cheating as I WANT to learn. Seems a waste of time and money to the individual if they cheat as all they will gain is some letters, which will prove useless if they go into a job claiming to be an expert when they are not, not the actual knowledge.
