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.

    A decade with the GSE: Reflections and insights

    By Belgin Elmas
    Reading time: 3 minutes

    Prof. Dr. Belgin Elmas is the Head of the Department of Foreign Languages at TED University Faculty of Education and Pearson GSE Ambassador for Turkey. In this post, Belgin discusses her teaching journey with the GSE over the last ten years, including the key lessons and experiences from this remarkable journey.

    In 2014, our rector presented me with the opportunity to be the director of the School of Foreign Languages at Anadolu University. Overwhelmed by the prospect of managing a thriving school with 3,500 students, 220 teachers and 220 staff members, I was hesitant. Despite the challenges I would face from training pre-service teachers at the Education Faculty, I was persuaded to take on the position.

    The Global Scale of English: A framework for success

    I remember my first day as the director, feeling overwhelmed by the workload and unsure how to manage it. While I won't delve into the details or the emotional roller coaster in this blog, I will share how the Global Scale of English (GSE) became my lifesaver. Faced with the challenge of creating a robust system to teach English to new university students who struggled in their initial year, I discovered the GSE. This detailed system guides learners throughout their language learning journey and I immediately knew, “YES, this is exactly what we need.”

    The GSE came to my rescue as I grappled with the task of establishing a robust system to teach English to university students. The GSE's detailed framework was exactly the tool we needed. Our team deliberated on how to integrate this system seamlessly into our curriculum. From deciding on the specific learning outcomes our students required, to choosing methods of teaching, creating materials and assessing outcomes, each decision was carefully considered. This process fostered growth, collaboration and enriched our teaching experiences as a team.

    A key resource

    The GSE played a crucial role in shaping curriculum development. The collaborative preparation with the GSE was invaluable for everyone, especially for me as a new director. We spent long hours enthusiastically shaping our new curriculum.

    Determining the entire curriculum, including materials and formative and summative assessment components, became more straightforward and with a clear understanding of what to teach and assess. Explaining the lessons to teachers and students became straightforward, thanks to the solid foundation provided by the GSE. This framework made curriculum development and implementation much smoother.

    Adapting to feedback and continuous improvement

    When we introduced the new curriculum in the 2014-2015 academic year, we received extensive feedback from both students and teachers on nearly every aspect – materials, midterms, quizzes, pace and more.  During my five-year tenure as director, we continually refined our curriculum and targeted specific facets of the curriculum each year for enhancement. For instance, one year we focused on assessment methods, while another year was devoted to teacher professional development. We applied a similar strategy to our German, French and Russian language programs, ensuring they understood our rationale and adopted comparable approaches in their curriculum development.

    Sharing our experiences of using the GSE in our curriculum developed a lot of interest, as everyone was searching for a more effective way to teach English. Whether at academic conferences or informal meetings, our team eagerly shared their knowledge and insights.

    The GSE today and beyond

    Today, at TED University, I serve as the head of the English Language Teaching Department. A key part of my mission is equipping future language teachers with the latest advancements and GSE forms a crucial part of this preparation. By incorporating the GSE into our pre-service teacher training program, we are ensuring that all teaching materials, lesson plans and assessment products include specific learning outcomes. This serves to build our teachers' confidence in their practice.

    Personal growth with GSE

    My 10-year journey with the GSE has profoundly influenced both my professional and personal life. The principles of the scale serve as a guide in every aspect of my daily life. For instance, during conversations, I often engage in an internal dialogue: "Belgin, what you're trying to explain is at a level 70, but the person you're speaking with is not there yet, so adjust your expectations." Or I might tell myself, "Belgin, you need to read more on this topic because you're still at level 55 and need to learn more to fully grasp what's happening here." As you can see, the GSE functions as a compass guiding every area of my life.

    If I were the Minister of National Education, I would unquestionably integrate the GSE into our national language education system. I would explain the rationale behind the scale and strive to implement a similarly detailed educational framework. This system would guide learners and teachers by indicating their current level, where they need to go and the steps required for each lesson in the curriculum. I hope that in the next 10 years, the GSE will serve as a guide for even more people around the world.

    Here's to the GSE – I am grateful for its existence; it’s made a huge impact on my life. Happy birthday!
