Many people are surprised at the idea of a computer program marking an exam paper. However, computer-based testing already exists in many different formats and many different areas. Many tests or exams that form part of our daily life are taken on computers. If you’ve ever learned to drive, sat a citizenship test, done a training course at work, or completed a placement test for a language course, the odds are that you’ve already taken an automated test.

Yet despite it being so common, there is still a lack of understanding when it comes to computer-based language assessment and how a computer can evaluate productive skills like speaking and writing.

Computer-based testing: a closer look

A common issue is that people have different ideas of what these tests entail. Computers can fulfill several essential roles in the testing process, but these often go unacknowledged. For example, a variety of test questions are needed to administer an exam, along with relevant data, and computers are used to store both the questions and the data. When it comes to creating randomized exams, computer software is used to select the exam questions, based on this data.

Computers can make complex calculations far more quickly and accurately than humans. This means that processes that previously took a long time are completed in days, rather than weeks.

Artificial intelligence (AI) technology is now capable of grading exam papers, for example. This means a shorter wait for exam results. In , candidates receive their results in an average of two days rather than waiting weeks for an examiner to mark their paper by hand.

The benefits for students and teachers

People take exams to prove their skills and abilities. Depending on their goals, the right result can open the door to many new opportunities, whether that is simply moving on to the next stage of a course, or something as life-changing as allowing you to take up your place on a university course in another country.

A qualification can act as a passport to a better career or an enhanced education, and for that reason, it’s important that both students and teachers can have faith in their results.

Computer programs have no inherent bias, which means that candidates can be confident that they will all be treated the same, regardless of their background, appearance or accent. , just one of ÃÛÌÒapp’s computer-based exams, offers students the chance to score additional points on the exam with innovative integrated test items.

This integration means that the results are a far more accurate depiction of the candidate’s abilities and provide a truer reflection of their linguistic prowess.

More than questions on a screen

It’s not as easy as simply transferring the questions onto a computer screen. All that does is remove the need for pen and paper; this is a missed opportunity to harness the precision and speed of a computer, as well as its learning potential.

Tests that have been fully digitized, such as PTE Academic, benefit from that automation; eliminating examiner bias, making the test fairer and calculating the results more quickly. Automated testing builds on the technological tradition of opening doors for the future – not closing them.

How technology enhances language testing

The development of automated testing technologies doesn’t merely make the examination process quicker and more accurate – it also gives us the chance to innovate. Speaking assessments are an excellent example of this.

Previously, this part of a language exam involved an interview, led by an examiner, who asked questions and elicited answers. But now that we have the technological capability, using a computer offers students the chance to be tested on a much wider range of speaking skills, without worrying about the inherent bias of the examiner.

Indeed, the use of a computer-based system facilitates integrated skills testing. Traditionally, language exams had separate papers focusing on the four skills of reading, listening, speaking and writing. But the more modern concept of language testing aims to assess these linguistic skills used together, just as they are in real-life situations.

Afterwards, the various scores are categorized to allow learners an insight into their strengths and weaknesses, which helps both students and teachers identify areas which need improvement. This useful feedback is only possible because of the accuracy and detail of automated exam grading.

The space race on paper

Back in the 1960s, during the space race, computers were still a relatively new concept. Kathleen Johnson, one of the first African-American women to work for NASA as a scientist, was a mathematician with a reputation for doing incredibly complex manual calculations. Although computers had made the orbital calculations, the astronauts on the first space flight refused to fly until Kathleen had checked those calculations three times.

This anecdote reminds us that - although computer technology is an inherent part of everyday life - now and then, we still need to check that their systems are working as they should. Human error still comes into play – after all, humans program these systems.

PTE Academic – a fully digitized exam

Every stage of PTE Academic, from registration to practice tests to results (both receiving and sharing them with institutions) happens online. It may come as a surprise to learn that the test itself is not taken online. Instead, students attend one of over 295 test centers to take the exam, which comes with the highest levels of data security.

This means that each student can sit the exam in an environment designed for that purpose. It also allows the receiving institutions, such as universities and colleges, to be assured of the validity of the PTE Academic result.

The future is here

We created computers, but they have surpassed us in many areas – exam grading being a case in point. Computers can score more accurately and consistently than humans, and they don’t get tired late in the day, or become distracted by a candidate’s accent.

The use of AI technology to grade student responses represents a giant leap forward in language testing, leading to fairer and more accurate student results. It also means more consistency in grading which benefits the institutions, such as universities, which rely on these scores to accurately reflect ability.

And here at ÃÛÌÒapp, we are invested in staying at the cutting edge of assessment. Our test developers are incorporating AI solutions now, using its learning capacity to create algorithms and build programs that can assess speaking and writing skills accurately and quickly. We’re expanding the horizons of English language assessment for students, teachers and all the other professionals involved in each stage of the language learning journey.

    7 ways to individualize your teaching

    Por Andrew Walkley
    Reading time: 4 minutes

    There's no denying that tailoring your teaching to individual students is an effective strategy. However, many teachers struggle with finding the time to include teaching moments which address an individual learner's specific needs. So, what's the best way to create an individualized classroom? Andrew Walkley, co-author of Roadmap, explains the benefits of this approach and shares some techniques to ensure that every student gets the most out of your lessons.Ìý

    The best of both worlds?

    First of all, what does individualized teaching mean? It's the concept that students will learn most effectively when the activity is specific to their needs and the language they are using is appropriate for their level. This concept is sometimes seen in opposition to coursebooks and class-based learning, where students are all expected to follow the same syllabus. However, class syllabuses and coursebooks have the following benefits:

    • Providing students with common goalsÌý
    • Encouraging learners to follow an unfamiliar topic that then opens new doors of learning
    • The learning opportunities in peer-to-peer explanationÌý

    When we talk about individualized teaching in the classroom, we want to exploit the benefits of learning together while also providing opportunities for more individualized development. So, how can you, as a teacher, combine the two approaches?

    1. Involve students in choosing your route

    All classroom groups are different and made up of people from different age groups with distinct needs and interests. Roadmap can help in two ways:

    1. There is a fast and slow track. The fast track focuses on language input and speaking. The slow track has additional skills lessons at the back of the book that are thematically linked to the corresponding fast track lesson.Ìý
    2. Each lesson has a clear goal and final task. For shorter courses, get each student to choose three tasks they would definitely like to do. Based on the results, you can prioritize those lessons.

    At the start of the course, make a point of asking about students' learning priorities and then plan accordingly. Once you've completed an input and speaking lesson, you can ask the students if they want to further explore the topic through the skills lesson.

    2. Make use of tasks

    Open tasks, where students exchange their own ideas in a meaningful way, are a key part of individualized lessons. In essence, they are self-differentiating because each student will attempt to complete the task using whatever language they are able to use. In Roadmap, each of the main lessons ends with a clear task connected to a Global Scale of English (GSE) can-do statement. However, there are also lots of other speaking opportunities without a 'speaking' label (under vocabulary or reading, etc.), as well as the conversation that typically occurs in any lesson, all of which can be treated as open tasks.

    3. Give individualized feedback and then share it

    In a group setting, it's impossible to give individual feedback on every single task. However, you can give individual attention to different people throughout the lesson. Make yourself available to give students the language they need as it arises during an activity. Then, when they've completed the task, write some of these examples on the board, but leave a gap for the keywords. Elicit these keywords from other members of the class. If they can't get it, ask the student(s) you helped to explain the missing language. You might then repeat the task, but this time, pay attention to a new group.Ìý

    4. Check what vocabulary students know

    All coursebook writers and teachers make choices about what vocabulary to introduce to students. In the case of Roadmap we are guided by the GSE and teachers might like to experiment themselves using the GSE Teacher Toolkit. However, all students will have their own lexicons. You can individualize learning better by asking students to rate the words you aim to cover in a unit according to whether they know them or not. For example, 1 = it's completely new, 2 = the meaning is familiar but I don't use it, 3 = this is part of my productive vocabulary.Ìý

    5. Get students to create their own word lists and cards

    This knowledge will enable you to encourage students to focus on their individual vocabulary needs. They can reinforce learning by developing a word list or making flashcards using a web tool such as Quizlet. For new words they may have a word/collocation with an L1 translation.

    With familiar vocabulary, they could have cards with a keyword on one side and varied collocations or common examples on the other (also in English). It's worth setting aside some time in class to do this at the start of a course. If your students are engaged and motivated, it can become a regular discipline for learning new vocabulary.Ìý

    6. Ask more open questions about usage, not just meaning

    When we do vocabulary tasks from the course material in class, we can use open questions to individualize learning with the following two techniques. Firstly, as you go through the answers, rather than going in order 1 to 8, you can nominate people to give the answer that they're most unsure of and want to check. Secondly, we can ask the rest of the class open questions which focus on how words are used. For example, take these questions from different vocabulary exercises in Roadmap B1+:

    • What (other) things might you spill?
    • Why might a character in a series be killed off?
    • What (else) can you describe as reliable?
    • What can someone do to stay calm?Ìý

    You could also ask questions such as, "What's the opposite of staying calm?" or "What might you say if you spilled something?"

    When you ask these questions, you are checking meaning, but more importantly, you are also pushing students to reveal how well they know a word. Do they know the collocations of spill and reliable? Do they have the other language they might need to talk about the aspects of a TV series or help someone who is in a panic? You can then encourage students to choose how much of this potentially new language they want to add to their word lists.

    7. Provide open homework tasks and make time to share the results

    Homework is another opportunity to individualize learning. Give students a wide choice of tasks based on the material of the course or beyond, for example:

    • Choose any number of exercises they want to do from workbook materialÌý
    • Find and read one article they are interested in (in L1 or L2)
    • Write five things they want to learn how to say in English (perhaps using Google Translate)
    • Write up an interesting conversation they had in English (the conversation could be originally in L1 or L2)

    Whatever task they choose, the key is to dedicate some classroom time to discussing which homework task they did and why. Encourage them to explain their answers and what they learned through the task, and whether or not they would choose to do a similar task again.ÌýÌý
