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 ɫèAV’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 ɫèAV, 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.

    Build success beyond the classroom: Critical thinking and assessment

    By Christina Cavage
    Reading time: 4 minutes

    There are some common myths related to critical thinking and assessment. Many people believe that it’s impossible to assess critical thinking, especially in classes where language is limited. However, it can be done! Here, the key to success is crafting tasks and rubrics that allow you to separate language skills and cognitive skills. After all, a low language level doesn’t necessarily reflect your student’s ability to think critically.

    So, how can we measure how a student knows rather than just what they know?

    How to measure critical thinking

    Well, we first have to consider two types of assessment—formal and informal. Formal assessments tend to happen at the end of a task, lesson or skill-building activity and usually focus on the work the student has produced. Then, we have informal assessments. Those are the assessments that involve on-the-spot interactions. These types of assessments play a crucial role in measuring critical thinking.

    Fostering critical thinking in the classroom

    By Christina Cavage

    Critical thinking is a term often thrown around the teacher’s lounge. You often hear, “Of course, teaching critical thinking is essential.” However, in that same space, we may also hear the question, “But how?”

    Teaching students to think critically involves helping them to develop a critical mindset. What exactly does that mean, and how can we do that?

    What does it mean to think critically?

    Critical thinking is a complex process that involves students reflecting, analyzing and evaluating ideas. Building a community of critical thinkers in our classrooms involves going beyond the cognitive domains and building the affective domains.

    The cognitive domain concerns subject knowledge and intellectual skills, whereas the affective domain involves emotional engagement with an idea or learning material.

    This deliberate teaching of critical thinking needs to be part of our teaching toolkit. We need to develop a mindset around it in and out of our classrooms.

    How can teachers develop a critical-thinking mindset?

    Consider all the questions we pose to students during our classes. Do we expect a yes or no answer, or have we established a classroom environment where students offer considered reasons for their responses?

    By following some guiding principles, we can get into the practice of naturally expecting deeper answers:

    1. Students need to engage in critical thinking tasks/activities at all levels.
    2. Teachers need to provide space/time in the classroom to build critical thinking learning opportunities.
    3. Practicing critical thinking must be incorporated throughout the course, increasing complexity as students improve their critical thinking ability.
    4. Students must be given opportunities to practice transferring critical thinking skills to other contexts.

    Activities to foster critical thinking in the classroom

    Activity/Strategy #1: Categorizing

    Provide a set of vocabulary terms or grammatical structures on the board (or pictures for true beginners). Ask your students to gather in pairs or small groups and have them categorize the list. Ask them to be creative and see how diverse the categories can be.

    Example:

    Desk, computer, pencil, stove, dishes, forks, novel, cookbook, sink, shelf

    • Made from trees: pencil, novel, cookbook, desk.
    • Made from metal: fork, stove, sink, etc.

    Activity/Strategy #2: What’s the problem?

    Provide students with a short reading or listening and have your students define a problem they read or hear.

    Tomas ran up the steps into Building A. The door was closed, but he opened it up. He was very late. He took his seat, feeling out of breath.

    • Determine why Tomas was late.
    • Underline verbs in the past tense.
    • Create a beginning or ending to the story.

    Activity/Strategy #3: Circles of possibility

    Present a problem or situation. Consider the problem presented in strategy #2 above: Ask the students to evaluate the situation from Tomas’ point of view, then, from the teacher’s point of view, and then from his classmate’s point of view.

    This activity generates many conversations, and even more critical thinking than you can imagine!

    Activity/Strategy #4: Draw connections

    Provide students with a list of topics or themes they have studied or are interested in. Place one in the center, and ask them to draw connections between each one.

    Afterward, they should explain their ideas. For example:

    “Energy and environment are affected by sports. Most sports do not harm the environment, but if you think about auto racing, it uses a lot of fuel. It can negatively impact the environment.”

    Activity/Strategy #5: What’s the rule?

    Play students an audio clip or provide them with a reading text. Draw students’ attention to a particular grammatical structure and ask them to deduce the rules.

    Activity/Strategy #5: Establishing context

    Show your class an image and put your students in small groups. Give each group a task. For example:

    The Jamestown settlement in the United States
    “A famous historic site is the Jamestown Settlement in Virginia. People from England were the first people to live in Jamestown. When did they arrive? They arrived in 1607. They built homes and other buildings. They looked for gold, silver and other materials. They sent the materials back to England. It was a hard life. Jamestown wasn’t a good place to settle. The winters were cold, and the settlers didn’t know how to protect themselves. After some time, they traded with the Native Americans, including tools for food. This helped the hungry settlers. Did many people die? Yes, many of the first settlers died. Later, more settlers arrived in Jamestown. It wasn’t easy, but in the end the settlement grew.”

    Ask questions like this:

    • If this were in a movie, what would the movie be about?
    • If this were an advertisement, what would it be advertising?
    • If this were a book, what would the book be about?

    There are many other wonderful strategies that can help build a classroom of critical thinkers. Getting your students accustomed to these types of tasks can increase their linguistic and affective competencies and critical thinking. In addition to these on-the-spot activities, consider building in project-based learning.

    How can you incorporate project-based learning into your classroom?

    Project-based learning often begins with a challenge or problem. Students explore and find answers over an extended period of time. These projects focus on building 21st Century Skills: Communication, Creativity, Collaboration, and Critical Thinking.

    They also represent what students are likely to encounter when they leave our English language classes.

    An example project

    Consider this project: Our cafeteria is outdated. It does not allow for food variety, or for guests to sit in groups of their desired size and activity level. Survey students who use the cafeteria. Follow up the survey with interviews. Determine how your group can reimagine the cafeteria. Prepare a proposal. Present your proposal.

    You can imagine the amount of language students will use working on this project, while, at the same time, building a critical mindset.

    Teaching critical thinking is all about building activities and strategies that become part of your teaching toolkit, and your students’ regular approach to problem-solving.

    Success beyond class: Critical thinking skills and academic english

    By Christina Cavage

    English for Academic Purposes (EAP) classes are designed to prepare students for higher education delivered in English. Students are expected to hold their own among a class full of fluent English speakers. So it’s essential that they have not only the language skills, but the academic and social skills that tertiary education demands today. And it’s up to teachers to ensure our students develop these skills – but that requires a balancing act.

    Many EAP courses lack the authenticity of the college classroom experience. Lectures are generally relatively short, only 5-10 minutes long. Reading is scaffolded, and the content is very structured, even overly structured. Then, our students move into their academic courses where they encounter two-hour lectures, 50+ pages of reading, and content that is far from scaffolded. So, how do we bridge these academic, linguistic and social gaps? Let’s look at some techniques to help students succeed in higher education.

    Bridging the linguistic gap

    Linguistics gaps may involve content-specific language, or the informal language students encounter when they work with other students, or the connotative and denotative meanings and contexts of a word. To bridge this gap, we need to build deep conceptual vocabulary knowledge. We don’t want students only to have label knowledge. Label knowledge allows students to pass a vocabulary text where matching or multiple choice is present. But that is not enough in an academic environment. Deep conceptual knowledge means truly knowing a word.

    So, what does it mean to know a word? Well, according to linguistics scholar Paul Nation, a student needs to know the following:

    • The spoken and written form
    • The parts of the word that have meaning
    • The word's forms and their meanings
    • The concepts and vocabulary associated with the word
    • The grammatical function, any collocations
    • The register and frequency of the word

    That is a whole lot!

    To build this extensive knowledge, we need to do so in an intentional manner. We need to build various activities that develop and foster critical thinking skills and engage students.

    Here is an example:

    “Hello! I am so glad to see so many of you at our special lecture today. Today, I am going to describe how a mixed community is planned and built. First, let’s look at what a mixed purpose community is, and then we will discuss the planning and building. As many of you know, a mixed purpose community is a neighborhood that includes residential spaces, business spaces, services and green spaces. How about the planning? First, when planning mixed purpose communities, architects, city planners and builders work together to plan where everything will be located. Because they want the community to be a fully walkable one, they need to think about how far homes are from schools, services and other businesses. Then, they carefully look at what kinds of businesses and services are needed. Next, they must design sidewalks so people can easily get to anywhere in the community, and not worry about car traffic. Today, planners are even looking at including bicycle paths, as more and more people are riding bicycles to work. Lastly, they need to consider the different types of residential space they will need. They build homes and apartments to attract all a wide variety of residents. These communities are becoming more and more popular, but planning them still takes time and a team of people.”

    The terms mixed and community are bolded. You can engage students with a simple noticing activity of how these words are used, the forms they take, the words around them, their collocations and the concepts associated with these words. An exercise like this will help students develop a deep understanding of these words. And that deep understanding will enable students to make connections and draw conclusions around these terms.

    Bridging the academic gap

    EAP students move from very scaffolded EAP courses to courses where they must listen and take notes for 50 minutes or read 50+ pages before class. Additionally, their professors often do not build background knowledge, or scaffold learning, as they expect students to enter their classrooms with this understanding. And this can create an academic gap.

    When it comes to bridging this gap, content can be the vehicle for instruction. Exposing students to the language of academic disciplines early on can build background knowledge, and be highly motivating for students who crave more than rote language instruction.

    Bringing the social gap

    When students enter their university courses they will be expected to work with peers, engage in group activities, negotiate, take turns and assert their own ideas into a dialogue. These social skills require language which needs to be developed and practiced in their EAP courses.
    You can do this by building instructional tasks and learning around developing and practicing critical thinking skills. Consider introducing project-based learning to your class. In project-based learning, students must work with their peers, learning how to prioritize, negotiate and assign responsibility. Bringing in these types of tasks and activities helps develop soft and critical thinking skills.
