How Effective are Online Assessment Systems?
This guest post is contributed by April Davis. She raises several important issues but her description of the existing scenario raises questions for me about whether we should be expecting more from 'assessment'. Should assessment be only summative, or if formative, when? - and by whom? Does assessment really help the learner? April writes:"There are many ways for students to assess their capabilities, and online assessment systems are just one of these. They’re being increasingly used today, not just by organizations and educational institutions to gauge if students and employees will be a right fit for the job or the degree, but also by those who want to assess themselves and see how good their chances are of getting into a course or gaining employment in the organization of their choice. Most online assessment exams test attitude and personality (or psychometric capabilities), and pre-employment skills. The efficacy of these assessment systems depends on a number of factors:
- The standardization of the tests – an online assessment system comprises a question bank and a question engine. The question bank must hold standardized question definitions in organized categories and contexts and the question engine must be able to pull these definitions based on user interaction. Also, the organization using the test must be sure that the assessment and analysis returned by the system are in conjunction with their values, beliefs and needs.
- The robustness of the system – since the tests are held online, the system has to make allowances for unexpected occurrences like lost connections, users pressing back and forward buttons indiscriminately or closing browser windows by mistake, server crashes, broken connections to the database and loss of data that has already been filled, and so on. Where these tests are timed the above problems could influence the accuracy of the results.
"For organizations that use these assessment systems, the relative success or failure of these tests can be gauged only in hindsight – the performance and attitude of the employees that the test recommends, when assessed over a period of time, helps companies decide if online assessment systems are effective in their hiring policies.
"However, it should also be noted that these tests are not a perfect science and that every employee changes in their attitude and personality based on the nature of the job and the environment in which they work. So while the test may throw up a few suitable candidates, it’s unrealistic to hope that they’re all going to be a good fit. The key to assessing the efficacy of these tests with some degree of accuracy is to give them some time, use a large number of employees as a test pool, and allow a few variances in your interpretation of the results."

Why should I bother?
There is a situation which I feel is endemic amongst many of our traditional academic institutions. Perhaps their argument is 'If it isn't broken, why mend it?' - little realising that the educational omnibus of 50 years ago is not helping today's students and teachers to get to where they want to be in the future. The vintage omnibus is not necessarily going in the right direction for everyone, particularly when more personal and individulaised vehicles can help learners get closer to where they want to be in a more satisfying way. I recently came across a post asking for responses to the statement below.“In truth, I can't say I've ever found much evidence of demand for any sort of e-portfolio tool among students, and to be honest there's comparatively little interest among academic staff in using them with students - except perhaps in subjects where portfolios are a professional requirement, and even then they tend to be very much driven by the needs of the certifying professional body.”
Why should students or teachers get excited about something that they do not appreciate? As long as an e-Portfolio is held up as an electronic CV or as a storage system for assessment of coursework no one is going to get inspired. As long as publications still suggest that an e-Portfolio can be held on a CD or flash drive we are still thinking ‘old technologies’.
Perhaps the problem is that of understanding new pedagogies:
- If staff were really looking for a method of capturing the transient interchanges of collaboration or peer review,
- if students realised how on-line formative assessment helps their academic progress,
- if they realised that the e-Portfolio was really an opportunity to share with others their deepest interests,
- if teachers realised that the e-Portfolio can often be a window into the souls of otherwise reticent students,
- if ownership of an e-Portfolio really gave opportunity for self-expression,
- if the e-Portfolio really was a Lifelong and Lifewide tool with full and uncompromised portability,
- if students and teachers realised the value of familial mentors,
- if the value of rich media was really understood,
- if both students and teachers really understood that the e-Portfolio can actually save time and allow both ‘travelling light’ and working where and when they choose, then perhaps the situation might be different.

When is an e-Portfolio not an e-Portfolio?
Nils Petersen on the AAEEBL forum recently pointed up this interesting example of what some were calling an 'e-Portfolio' where others were perhaps more correctly calling it her 'electronic reputation' or as Serge Ravet would say, 'her digital identity'. The work of Margo Tamez as illustrated by the Touchgraph that she created hit the courts when litigation ensued as to the ownership rights of an e-Portfolio created as part of her academic work. This is a classic example of 'Cloud Computing' and raises the whole issue of 'who owns what'?
Traditionally, any work created in the workplace belonged to the owners of the company and similarly, any work created using the tools of the workplace, either on-site or off-site still belonged to the company. But that is not the point of this post.
Firstly, as I have stated before, the e-Portfolio should not be considered as a 'pantechnicon' of all that a student has ever produced. Rather, the e-Portfolio should be seen as that selection of appropriate artefacts, either work in progress or completed activities that the learner feels are the best exemplars of learning processes.
Secondly, the e-Portfolio should be that organised and well presented selection of artefacts supported by intelligent comment for a particlar audience. I cannot begin to think that Margo has a particular audience in mind for this tumble of evidences.

Instructional Technology in Schools
"The Use of Instructional Technology in Schools examines teachers' use of the major instructional technologies over the last century — from the days of silent film, radio and slide shows through to the modern interactive whiteboard and the Web. It explores the reasons why so few teachers have used these technologies and why, even in today's digital world, the most commonly used classroom tools are the pen, paper and teaching board."I make no apology for including this 'advert' as I helped in some of the discussions with Mal Lee about the evolving use of technologies in the UK. However, I have just been informed by Eurospan Limited, the UK branch of ACER Press, that they are offering a 15% discount on Mal Lee's books to educationists. The 'blurb' goes on to say:
"The book provides decision makers with an invaluable insight into the million dollar question: What is required to get all teachers across the nation using the appropriate instructional technology as a normal part of everyday teaching? Without question, student learning is enhanced by adopting these new technologies.
"Until now, research on why the majority of teachers use only the most basic tools in the classroom has been scarce. The Use of Instructional Technology in Schools examines this phenomenon and, most importantly, identifies what is required to achieve teachers' universal acceptance of instructional technologies."
