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 PTE Academic, 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. PTE Academic, just one of Pearson’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 Pearson, 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.

    Understanding dialects in the English language

    By Charlotte Guest
    Reading time: 7 minutes

    Language reflects the diversity of human culture and society. Among its most fascinating parts are dialects, regional or social varieties of a language distinguished by pronunciation, grammar and vocabulary. Dialects are the heartbeat of a language, pulsing with the rich stories, traditions and identities of those who speak them.

    Understanding a language and dialect, and its significance, can enrich the learning experience for language learners, offering a deeper appreciation of a language and its speakers. Dialects are not just variations within a language; they are often considered separate entities, each with its own rich history and cultural significance, highlighting the complexity and diversity of linguistic expression.

    What exactly is a regional dialect?

    At its core, a dialect is a variation of a language spoken by a particular group of people. However, the distinction between dialects and a different language can often be subjective. These variations can occur due to geographical, social class, ethnic, or historical reasons. While all speakers of a language share the same basic grammar rules and vocabulary, those speaking different dialects might use unique words and slang or have distinct pronunciations, highlighting the lack of an objective difference between dialects and languages.

    For instance, British and American English are two dialects of the English language that are mutually intelligible, meaning speakers of either dialect can understand, and be understood, by the other. They share the same foundational grammar and most of the core vocabulary but differ in pronunciation, spelling, and some aspects of vocabulary and idioms. Similarly, within Britain or the United States, there are numerous regional dialects (e.g., Yorkshire English, Southern American English) that further showcase the diversity within a single language. Some of these dialects are considered by their speakers to be distinct languages, emphasizing the complex nature of linguistic identity and classification.

    What is an example of a dialect?

    An example of dialect variation can be seen in the Italian language, which boasts a wide range of regional dialects, showcasing linguistic diversity with multiple dialects spoken across Italy.

    For example, the Tuscan dialect has historically been recognized as the basis for standard Italian, largely due to its use in influential literature. However, other dialects from regions like Sicily or Lombardy vary significantly from Tuscan Italian in terms of pronunciation, vocabulary and syntax, reflecting the diverse cultural landscapes and histories of Italy’s regions.

    Another example of this variation of dialect within a single language is found in the United Kingdom. For instance, the Cockney dialect, originating from London’s East End, is renowned for its rhyming slang and distinct vowel sounds, serving as a prime example of spoken dialects that emphasize the importance of oral tradition. Contrastingly, the Geordie dialect, native to Newcastle and the surrounding areas, boasts an entirely different set of vocabulary, pronunciation patterns, and even grammatical structures, further highlighting the diverse range of spoken dialects within the standard English language.

    What is the difference between a dialect and an accent?

    The distinction between a dialect and an accent is subtle yet significant. An accent relates solely to differences in pronunciation - the distinct manner in which people say words, often influenced by unique speech patterns that can vary significantly across different languages and regions.

    In contrast, a dialect encompasses not only pronunciation and accent but also includes specific grammar and vocabulary. Accents can be a component of a dialect, but dialects offer a broader spectrum of linguistic variety, including lexical and grammatical differences.

    For instance, someone might speak English with a Scottish accent but use the same grammatical structures and vocabulary as an English speaker from London; however, Scots, a variety spoken in Scotland, is considered a dialect (or even a separate, distinct language, by some) because it possesses unique grammar, vocabulary and pronunciation.

    Why are different dialects important?

    Dialects are more than just linguistic variations; they are windows into communities' cultural and social fabric. They carry with them histories, traditions and the identity of their speakers. Some dialects are even considered 'distinct languages' by their speakers, highlighting the deep cultural significance of these linguistic forms. Learning about dialects, including regional dialects, can thus offer insights into:

    • Cultural contexts: Understanding the dialects of a language, especially regional dialects, can provide language learners with a richer cultural understanding and a more nuanced perspective of the language’s speakers. This exploration into regional dialects reveals the arbitrary distinction between 'standard' and 'nonstandard' dialects, which is often based on social, political, cultural, or historical considerations.
    • Social dynamics: Dialects can reflect social distinctions, historical migrations and contact with other languages, offering clues about social hierarchies, historical conflicts and integrations.
    • Language evolution: Studying dialects reveals how languages change over time, adapting to societies' needs, migrations and innovations.
