Digital assessment is becoming more and more widespread in recent years. But what’s the role of digital assessment in teaching today? We’d like to give you some insight into digital assessment and automated scoring.

Just a few years ago, there may have been doubts about the role of AI in English assessment and the ability of a computer to score language tests accurately. But today, thousands of teachers worldwide use automated language tests to assess their students’ language proficiency.

For example, ɫèAV’s suite of Versant tests have been delivering automated language assessments for nearly 25 years. And since its launch in 1996, over 350 million tests have been scored. The same technology is used in ɫèAV’s Benchmark and Level tests.

So what makes automated scoring systems so reliable?

Huge data sets of exam answers and results are used to train artificial intelligence machine learning technology to score English tests the same way that human markers do. This way, we’re not replacing human judgment; we’re just teaching computers to replicate it.

Of course, computers are much more efficient than humans. They don’t mind monotonous work and don’t make mistakes (the standard marking error of an AI-scored test is lower than that of a human-scored test). So we can get unbiased, accurate, and consistent scores.

The top benefits of automated scoring are speed, reliability, flexibility, and free from bias.

Speed

The main advantage computers have over humans is that they can quickly process complex information. Digital assessments can often provide an instant score turnaround. We can get accurate, reliable results within minutes. And that’s not just for multiple-choice answers but complex responses, too.

The benefit for teachers and institutions is that they can have hundreds, thousands, or tens of thousands of learners taking a test simultaneously and instantly receive a score.

The sooner you have scores, the sooner you can make decisions about placement and students’ language level or benchmark a learner’s strengths and weaknesses and make adjustments to learning that drive improvement and progress.

Flexibility

The next biggest benefit of digital assessment is flexible delivery models. This has become increasingly more important since online learning has become more prominent.

Accessibility became key: how can your institution provide access to assessment for your learners, if you can’t deliver tests on school premises?

The answer is digital assessment.

For example, Versant, our web-based test can be delivered online or offline, on-site or off-site. All test-takers need is a computer and a headset with a microphone. They can take the test anywhere, any time of day, any day of the week, making it very flexible to fit into someone's schedule or situation.

Free from bias

Impartiality is another important benefit of AI-based scoring. The AI engine used to score digital proficiency tests is completely free from bias. It doesn’t get tired, and it doesn’t have good and bad days like human markers do. And it doesn’t have a personality.

While some human markers are more generous and others are more strict, AI is always equally fair. Thanks to this, automated scoring provides consistent, standardized scores, no matter who’s taking the test.

If you’re testing students from around the world, with different backgrounds, they will be scored solely on their level of English, in a perfectly objective way.

Additional benefits of automated scoring are security and cost.

Security

Digital assessments are more difficult to monitor than in-person tests, so security is a valid concern. One way to deal with this is remote monitoring.

Remote proctoring adds an extra layer of security, so test administrators can be confident that learners taking the test from home don’t cheat.

For example, our software captures a video of test takers, and the AI detection system automatically flags suspicious test-taker behavior. Test administrators can access the video anytime for audits and reviews, and easily find suspicious segments highlighted by our AI.

Here are a few examples of suspicious behavior that our system might flag:

Image monitoring:

  • A different face or multiple faces appearing in the frame
  • Camera blocked

Browser monitoring:

  • Navigating away from the test window or changing tabs multiple times

Video monitoring:

  • Test taker moving out of camera view
  • More than one person in the camera view
  • Looking away from the camera multiple times

Cost

Last but not least, the cost of automated English certifications are a benefit. Indeed, automated scoring can be a more cost-effective way of monitoring tests, primarily because it saves time and resources.

ɫèAV English proficiency assessments are highly scalable and don’t require extra time from human scorers, no matter how many test-takers you have.

Plus, there’s no need to spend time and money on training markers or purchasing equipment.

AI is helping to lead the way with efficient, accessible, fair and cost-effective English test marking/management. Given time it should develop even further, becoming even more advanced and being of even more help within the world of English language learning and assessments.

    What is rapid prototyping and how can it apply to the ELT classroom?

    By Nicole Kyriacou
    Reading time: 5 minutes

    Tom Chi is an internet veteran with quite a resumé. His roles have been many and varied – from astrophysical researcher to Fortune 500 consultant and corporate executive, developing new hardware and software products and services.

    He worked on Microsoft Outlook when it was in its infancy, was a major influence in taking Yahoo Search from 0 to 90 million users and is now Head of Product Experience at Google X – Alphabet’s secretive division focused on creating technological innovations for the future. It has produced the self-driving car and Google Glass, and its Project Loon aims to provide internet to every square inch of the earth.

    At Google X, Tom was in a unique position – always having to think five, ten or even more years ahead in order to conceptualize and build the technology of the future. As you might imagine, this is far from an easy task; not only do the ideas have to be original, but they have to meet people’s future needs – something that is not easy to predict.

    So, how does Tom and the others at Google X deliver their vision for the future using today's materials and technology?

    That’s where Rapid Prototyping comes in. It’s a concept that allows teams to experiment, learn and adjust prototypes quickly and cheaply, so that projects (and products) get off the ground. Failure is seen as a starting block and an inevitable part of the learning process. Following his workshop, we are going to look further at rapid prototyping and how it can relate to the ELT classroom.

    Three ways English students can learn to read at home

    Read more at home if you want to learn English faster: three ways to get into the habit

    I can hear parents, ELT learners and teachers all over the world thinking to themselves: We know it helps if English students learn to read for pleasure at home, but how are we supposed to find the time? Who is buying these materials? What if a parent doesn’t speak English themselves?

    That’s the beauty of reading at home, also called extensive reading: it’s completely autonomous and parents can be as involved as much or little as they like. There’s more good news as it’s never been cheaper to assemble a selection of extensive readers for your children or students, meaning that cost is no longer so much of a barrier to reading at home.

    Is extensive reading really that critical to learning English?

    Stephen D. Krashen’s [1]offers a marvellous summary and critique of extensive reading studies around the world, concluding that:

    "When [second language learners] read for pleasure, they can continue to improve in their second language without classes, without teachers, without study and even without people to converse with.’"(Krashen 1993 p. 84)

    Philip Prowse’s excellent article, “What is the secret of extensive reading?”[2]agrees with Krashen’s conclusion.

    Prowse goes into more detail about efficacy studies at primary, secondary and adult levels. This body of evidence finds that reading for pleasure improves results in grammar, writing, speaking and fluency, as well as comprehension and vocabulary – both alongside and instead of traditional textbooks.

    So, we know it works. As with so many education-related things, the question is how to implement them. Christine Nuttall talks about the virtuous circle of reading – once a learner begins to enjoy reading, they are more likely to read more and benefit more from it, so they learn to read more, and so on.

    The reverse is also true. The questions then follow: how do we motivate our Instakids to read at home in English, if they won’t read in their first language? How do we carve out time between travel, work, school and homework? Here are three ways you can form the habit of reading at home:

    1. Learners need access to extensive reading material at home to use it

    Krashen establishes this common-sense fact based on five studies from 1983 to 2003.[2]It can be a reading app, an online library subscription or a pile of readers in the corner – whatever it is, it has to be the right level for the student and it has to be a topic they’re interested in, or they’ll never learn to read for pleasure.

    Negative reading habits can happen simply because there isn’t much available to the learner: Worthy and McCool studied 11 sixth-graders in 1998 who "hated to read", and found a direct correlation between those students and the lack of reading material at home.[3] Thankfully, we now have more options than we used to:

    For extensive reading online, the Extensive Reading Foundation offers good-quality, free materials, in audio and print, at its .These text resources and audiobooks tend to be quite basic and the stories are largely classics. You can choose by level and genre, and there is also a publisher directory.

    • You can purchase full ɫèAV English Readers and other publishers’ Kindle editions on the Kindle store, iBookstore and Google Play, and read them on an e-reader, phone or tablet using the Kindle app. These are finely-graded, contemporary, relevant e-books with titles like , , , , , , and .
    • An e-book library subscription can be a cost-effective way to get access to a lot of e-books online through your browser. is a Japanese-run online library which offers hundreds of full-text graded readers, from reputable publishers, and charges about $19 per year.
    • For print readers, cost can be an issue. If you can't buy readers at your local bookshop from a publisher like ɫèAV, you can buy first- or second-hand readers cheaply from Amazon or the Book Depository, or you can ask your school to let you know when they’re upgrading their readers library, as you may be able to take some of the older books home.

    2.Make the most of the commute or the school run

    The key here is routine – give it a try and see if it works for you. Reading doesn’t just happen on a page. Today’s English learners have multiple ways to read for pleasure on their various devices as well as in print, all of which are well-adapted for reading and listening on the train/on the bus/in the car/on foot.

    I listen to podcasts on my commute by train and, to this day, I know my times tables thanks to a tape my mother used to play in the car on the way to primary school.

    • Download a podcast or audiobook. Ideally, an English learner would both read and listen, but one or the other is better than nothing. Audible.com has plenty of English extensive readers in audiobook format, and a year’s membership is $10 per month, or you can buy individual audiobooks. There are classic extensive reading podcasts available on iTunes for $4.99 each.
    • Never underestimate your public library.is an online service that finds your local library for you, wherever you are in the world. You can also search by title and see which libraries carry that particular book. Just think: you could create an instant, extensive reading library at your home for free that changes every month.

    3. Consider the power of rewards

    You can reward your child or reward yourself for building a reading habit. Remember, we are talking about starting a virtuous circle: persuading a learner to begin a new habit of reading in English for pleasure. Reward mechanisms can be very effective.

    This idea should be explored on a case-by-case basis – it depends on what you or your child responds to best. In my opinion, starting a reading habit is well worth a glass of wine, a chocolate treat, or an extra half-hour playing video games.
