When entering the world of language proficiency tests, test takers are often faced with a dilemma: Should they opt for tests scored by humans or those assessed by artificial intelligence (AI)? The choice might seem trivial at first, but understanding the differences between AI scoring and human language test scoring can significantly impact preparation strategy and, ultimately, determine test outcomes.

The human touch in language proficiency testing and scoring

Historically, language tests have been scored by human assessors. This method leverages the nuanced understanding that humans have of language, including idiomatic expressions, cultural references, and the subtleties of tone and even writing style, akin to the capabilities of the human brain. Human scorers can appreciate the creative and original use of language, potentially rewarding test takers for flair and originality in their answers. Scorers are particularly effective at evaluating progress or achievement tests, which are designed to assess a student's language knowledge and progress after completing a particular chapter, unit, or at the end of a course, reflecting how well the language tester is performing in their language learning studies.

One significant difference between human and AI scoring is how they handle context. Human scorers can understand the significance and implications of a particular word or phrase in a given context, while AI algorithms rely on predetermined rules and datasets.

The adaptability and learning capabilities of human brains contribute significantly to the effectiveness of scoring in language tests, mirroring how these brains adjust and learn from new information.

Advantages:

  • Nuanced understanding: Human scorers are adept at interpreting the complexities and nuances of language that AI might miss.
  • Contextual flexibility: Humans can consider context beyond the written or spoken word, understanding cultural and situational implications.

Disadvantages:

  • Subjectivity and inconsistency: Despite rigorous training, human-based scoring can introduce a level of subjectivity and variability, potentially affecting the fairness and reliability of scores.
  • Time and resource intensive: Human-based scoring is labor-intensive and time-consuming, often resulting in longer waiting times for results.
  • Human bias: Assessors, despite being highly trained and experienced, bring their own perspectives, preferences and preconceptions into the grading process. This can lead to variability in scoring, where two equally competent test takers might receive different scores based on the scorer's subjective judgment.

The rise of AI in language test scoring

With advancements in technology, AI-based scoring systems have started to play a significant role in language assessment. These systems utilize algorithms and natural language processing (NLP) techniques to evaluate test responses. AI scoring promises objectivity and efficiency, offering a standardized way to assess language and proficiency level.

Advantages:

  • Consistency: AI scoring systems provide a consistent scoring method, applying the same criteria across all test takers, thereby reducing the potential for bias.
  • Speed: AI can process and score tests much faster than human scorers can, leading to quicker results turnaround.
  • Great for more nervous testers: Not everyone likes having to take a test in front of a person, so AI removes that extra stress.

Disadvantages:

  • Lack of nuance recognition: AI may not fully understand subtle nuances, creativity, or complex structures in language the way a human scorer can.
  • Dependence on data: The effectiveness of AI scoring is heavily reliant on the data it has been trained on, which can limit its ability to interpret less common responses accurately.

Making the choice

When deciding between tests scored by humans or AI, consider the following factors:

  • Your strengths: If you have a creative flair and excel at expressing original thoughts, human-scored tests might appreciate your unique approach more. Conversely, if you excel in structured language use and clear, concise expression, AI-scored tests could work to your advantage.
  • Your goals: Consider why you're taking the test. Some organizations might prefer one scoring method over the other, so it's worth investigating their preferences.
  • Preparation time: If you're on a tight schedule, the quicker turnaround time of AI-scored tests might be beneficial.

Ultimately, both scoring methods aim to measure and assess language proficiency accurately. The key is understanding how each approach aligns with your personal strengths and goals.

The bias factor in language testing

An often-discussed concern in both AI and human language test scoring is the issue of bias. With AI scoring, biases can be ingrained in the algorithms due to the data they are trained on, but if the system is well designed, bias can be removed and provide fairer scoring.

Conversely speaking, human scorers, despite their best efforts to remain objective, bring their own subconscious biases to the evaluation process. These biases might be related to a test taker's accent, dialect, or even the content of their responses, which could subtly influence the scorer's perceptions and judgments. Efforts are continually made to mitigate these biases in both approaches to ensure a fair and equitable assessment for all test takers.

Preparing for success in foreign language proficiency tests

Regardless of the scoring method, thorough preparation remains, of course, crucial. Familiarize yourself with the test format, practice under timed conditions, and seek feedback on your performance, whether from teachers, peers, or through self-assessment tools.

The distinctions between AI scoring and human in language tests continue to blur, with many exams now incorporating a mix of both to have students leverage their respective strengths. Understanding and interpreting written language is essential in preparing for language proficiency tests, especially for reading tests. By understanding these differences, test takers can better prepare for their exams, setting themselves up for the best possible outcome.

Will AI replace human-marked tests?

The question of whether AI will replace markers in language tests is complex and multifaceted. On one hand, the efficiency, consistency and scalability of AI scoring systems present a compelling case for their increased utilization. These systems can process vast numbers of tests in a fraction of the time it takes markers, providing quick feedback that is invaluable in educational settings. On the other hand, the nuanced understanding, contextual knowledge, flexibility, and ability to appreciate the subtleties of language that human markers bring to the table are qualities that AI has yet to fully replicate.

Both AI and human-based scoring aim to accurately assess language proficiency levels, such as those defined by the Common European Framework of Reference for Languages or the Global Scale of English, where a level like C2 or 85-90 indicates that a student can understand virtually everything, master the foreign language perfectly, and potentially have superior knowledge compared to a native speaker.

The integration of AI in language testing is less about replacement and more about complementing and enhancing the existing processes. AI can handle the objective, clear-cut aspects of language testing, freeing markers to focus on the more subjective, nuanced responses that require a human touch. This hybrid approach could lead to a more robust, efficient and fair assessment system, leveraging the strengths of both humans and AI.

Future developments in AI technology and machine learning may narrow the gap between AI and human grading capabilities. However, the ethical considerations, such as ensuring fairness and addressing bias, along with the desire to maintain a human element in education, suggest that a balanced approach will persist. In conclusion, while AI will increasingly play a significant role in language testing, it is unlikely to completely replace markers. Instead, the future lies in finding the optimal synergy between technological advancements and human judgment to enhance the fairness, accuracy and efficiency of language proficiency assessments.

    Reducing exam day stress

    By Amy Malloy

    What are the origins of exam-day stress?

    There’s no doubt about it – exams are scary. But why exactly is this? What is it about an exam scenario that stresses us out and how can we make it feel okay?

    To answer these questions, we’re going to have to take a trip back in time and look at how our ancestors evolved their abstract thinking skills. At the same time, we’ll look at how mindfulness can actively help shift the way we think about exams.

    About 70,000 years ago, or thereabouts, a critical development happened in how the human brain processed experiences.

    Over a relatively short time (in evolutionary terms), scientists believe we stopped simply experiencing primal urges (safety/hunger/tiredness etc.) and responding to them.

    Instead, we started to be able to imagine, analyze and believe in things that didn’t exist. This meant not only could our brains respond to the threat of a real predator in front of us, but also to the perceived or imagined threat of a predator. This shift had really interesting consequences for our future relationship to threat.

    Developing imaginations also meant we started to believe in the same things as our peer groups. As a result, if a member of the tribe stopped behaving in a way that supported the tribe’s survival, other members might start to doubt their usefulness as a member of the community.

    At this time, social isolation meant no share of the food and no protection against predators. Inclusion was directly linked to survival. Essentially the physiological consequences of not meeting societal expectations were the same as coming face-to-face with a lion: fight or flight.

    Why is fight or flight mode a problem for exam performance?

    Fast forward to the present day and the context of English language exams. Exams are a type of societal expectation: a standard of language proficiency which a student is required to meet to prove their usefulness in a community who speaks that language.

    Thinking about it this way, it’s no wonder we can experience stress and panic at the thought of an exam or in the exam room itself. In evolutionary terms, an exam = a lion or the possibility of social exclusion!

    Fight or flight mode is designed to help us overcome or escape danger as quickly as possible.

    When fight or flight is activated, our brain shuts down the bodily functions it doesn’t need to survive. This includes digestion, language creation, creative and strategic thinking, writing, and deeper breathing.

    Unfortunately, some of these are key to performing well in a language exam!

    that, especially in an exam course context, “extremely high stress levels[…] can affect your cognition, negatively impacting your memory and ability to complete a task. Over time, chronically high stress levels can also impair your ability to form new memories, so high stress levels all semester long could impact your final exam performance later.”

    This means that high stress levels in the exam make it hard to perform at one’s best, and stress in anticipation of the exam can mean that the content is not learned properly in the first place.

    What can teachers do to help?

    Ultimately, we want to make the exam scenario seem safe. When our mind and body do not perceive danger, they will allow the ‘rest and digest’ functions to become active and allow our performance to flow.

    There will of course be some nerves. But the key is to help the student stay in that sweet spot of clear thinking before the stress takes over and turns into panic.

    Here are three ways we can help:

    1. Practice mindful breathing

    Practice some simple mindful breathing with your students. Mindfulness refers to the awareness that we find by focusing consciously on the present moment, objectively, with compassion and without judgment.

    It takes us back into the physical reality of the present moment and out of anxious thought cycles, which can make our stress spiral out of control. Practicing regularly ahead of the exam will help build up neural connections in the brain around the areas that help us relax and .

    The following straightforward routine can be used both regularly at the start of class and by the student in the exam itself if they feel panic rising:

    • STOP: Close your eyes. Take a moment to notice the physical sensation of the chair beneath you and the floor underneath your feet. Notice the sounds around you in the room and allow them simply to flow in and out without needing to follow them.
    • BREATHE: Focus your attention gently on your breath going in and out of your nose at the tip of the nostrils. Count ten breaths in and out, seeing if you can notice something new about each one. If you feel panicky, allow the breath out to continue a little longer than the breath in.
    • WATCH: Become aware of your thoughts and allow them to simply come and go, like clouds across the sky. Notice if you are holding on to something from the past or striving towards something in the future. Allow these to simply release and take your attention back to the breath in the present moment. Count another ten breaths. Then open your eyes and come back into the room.

    2. Familiarize your students with the exam scenario

    Make the exam scenario as familiar as possible in advance. Anything you can do to make the exam conditions appear less threatening ahead of exam day will be of great benefit.

    This may be as simple as making conditions surrounding regular progress assessments as close to the main exam as possible, so it is less strange on the day. If you have control over the exam day itself, make this as low pressure as possible.

    3. Help students develop a growth mindset

    Foster a growth mindset with your students by using the word ‘yet’ with them. Encourage them to replace ‘I can’t do it’ with ‘I can’t do it yet’. This simple word takes them out of comparison mode with where they think they should be in terms of language ability and helps them stay focused on where they are, reducing self-pressure.

    All of the above strategies are designed to take away the threat of a lion in the exam room when the day comes.

    Wishing your students all the very best for their exam preparation and good luck!

    Mindfulness for teachers: managing expectations over the holidays

    By Amy Malloy

    Mindfulness and your routine

    In the run-up to the holidays, it is common to feel like your routine has completely broken down, especially when you’re not giving classes or working at school. The holidays also often bring with them lots of people, family, and excitement. That sometimes means we also experience fluctuating emotions, stress and the feeling that everything should be perfect.

    On top of this, shops and social media are filled with advertising – and there’s definitely more ‘stuff’ to buy. In addition, we can see messages telling us we need to feel ‘merry’ and ‘bright’ wherever we look. Even the popular greeting, ‘Merry Christmas’, can sometimes feel less of a greeting and more of an instruction.

    Sometimes it feels like the people around us expect us to always feel happy and joyful over the holiday season. This is fine if we do feel merry, but we will always have ups and downs. If you don’t feel happy, for whatever reason, it can feel even harder than it might at times where there is less expectation all around us.

    Overcoming the challenge

    Finding a way to introduce mindfulness into the holiday season can be a wonderful way for us to understand our emotions at this time of year. It will help you think about your expectations and let you find a moment to pause to accept whatever the reality actually is.

    Here are some quick and easy ways to find some ‘you’ time and keep checking in with how you’re feeling. These are also tips you can try with children in the classroom and for yourself at home to keep yourself on track.

    3-minute body scan

    Find a quiet moment. This may be in the few minutes after you wake up or go to bed, during break time, or even at the start of a lesson.

    • Notice the contact of your feet with the floor. Notice the sounds around you in the room.
    • Take three deep breaths and notice how they feel.
    • Scan down the body in your mind from the top of your head all the way down to your toes. Observe what you notice about your body with an air of curiosity – look for any tension, discomfort or comfort. Also, notice if there are any expectations you have of that day or moment. See if you can simply notice them and set them aside. This curiosity helps us stay detached from what we notice so we can just observe.
    • Take three more deep breaths, and carry on.

    2-minute notebook

    Writing something down can be a wonderfully mindful exercise. Have a stack of post-its or a little notebook on your desk or bedside table. You could encourage your students to do the same.

    1. Pick a point in your day. It could be at the start of each day, the start of each lesson, or just before bed. Each day, at that time, take a moment to write down three:

    • good things that have happened in your day
    • things that felt challenging
    • things you feel grateful and thankful for.

    2. Review your notes every now and again during the holiday period. This will give you a sense of your shifts of mood and energy that might have occurred.

    Noticing something you feel grateful for has been shown to .

    1-minute cupboard pause

    When things feel over-stimulating, find a quiet space just for a minute. Even if it’s in a cupboard!

    STOP: notice the contact of your feet with the floor.
    BREATHE: take ten deep breaths, breathing in for a count of four and out for a count of six.
    WATCH: watch each breath coming and going from the nose or chest or belly. Observe what your thoughts and feelings are doing. Allow them to sit without needing to respond.

    Then head back into the area you were in.

    I hope these tips help you to navigate the festive season without expectation and with curiosity for what each moment holds along the way.

    Remember that the holiday days you celebrate are really just normal days. It’s simply that expectations have changed, and what’s more, everyone’s expectations will be different.

    Simply taking time to notice this can make a massive difference to the pressure we put on ourselves. Releasing this pressure can even lead to more enjoyment overall – so why don’t you try it and see?

    Understanding and managing technostress

    By Amy Malloy

    What is technostress?

    Technostress affects people in different ways. I resonate with Chiapetta’s (2017) definition:

    “Technostress is a syndrome that occurs when the person, subjected to information overload and continuous contact with most digital devices, develops a state of stress.”

    This explanation isn’t limited to any particular symptoms. However, most of us can relate to being over-exposed to technological devices – especially in the past year. Consequently, I imagine many people have experienced some symptoms of technostress as a result.

    What are the symptoms of technostress?

    While the symptoms of technostress differ, there are a number of common experiences. Perhaps you obsessively check social media, or struggle to focus on everyday tasks. Or maybe you feel demotivated and low in mood. You might find yourself overly focused on getting the latest technology. Or you might be actively avoiding or feeling anxious about using technology.

    Why should we be concerned about technostress?

    People are adaptable, it’s part of our biology, but if change happens too quickly, we experience symptoms of stress. And, in our modern, continuously busy culture, it can be easy to assume something is wrong with us if we feel we can’t cope with technology. It can feel like we’re failing because we’re not focusing or achieving enough. We might also feel stupid for not understanding how a piece of software works.

    In response, we need to find ways to relieve that stress and return to a more restful state.

    Tips to prevent and manage technostress

    1. Switch off – This may be hard to do with the demands of life but sometimes, just turning your devices off and stepping away from technology is the best approach. Do something to pull you away from the information overload, like a walk in nature or reading a fictional book. Something that pulls you away from life’s goings-on.
    2. Limit your exposure – If you can’t switch off completely for whatever reason, then maybe rationing your exposure to devices is key. Time and limit your time on devices, taking regular breaks away. If you struggle to pull yourself away, there are apps and device functions that can restrict access for you.
    3. Only use with a purpose – Before you start using technology, ask yourself: “What am I using this for?”. Study? Research? Or is it just out of boredom? If you haven’t got a set aim or goal, then you are likely to mindlessly scroll and get pulled into the vast information overload of social media and the web. Try to avoid this by having a set aim/goal when using technology.
