The role of AI in English assessment

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.

In today’s fast-paced world, finding time for self-care is more important than ever. Among a range of traditional self-care practices, learning a language emerges as an unexpected but incredibly rewarding approach. Learning a foreign language is a key aspect of personal development and can help your mental health, offering benefits like improved career opportunities, enhanced creativity, and the ability to connect with people from diverse cultures.

Pearson’s recent report, “How English empowers your tomorrow,” carries significant implications for educators. It underlines that increased English proficiency correlates with improved economic and social outcomes. Educational institutions play a crucial role in preparing students for professional success, employing various pedagogical approaches and teaching methods to meet the diverse needs of learners across universities, colleges and schools. However, the main unfortunate result of the report for educators is the argument that learners are leaving formal education without the essential skills required to achieve these better outcomes.

Furthermore, as stated in the report, many of them are not lucky enough to be adequately equipped for the demands of their professional roles as they continue their careers. This emphasizes educators’ underlying responsibility to critically evaluate their teaching and assessment methods to ensure their students are effectively prepared for real-world challenges, especially as they transition into higher education where the stakes for academic and professional success are significantly elevated.

The data of the report comes from five countries, and while Turkey is not one of them, many of the findings are still relevant to the English language education system in Turkey. Given the significant investment of time and effort, with foreign language education starting in the second grade for the majority of students in the Ministry of National Education schools, better outcomes would be expected in mastering the global language.

Numerous reasons contributing to this failure could be listed but I would put the perception of how language is defined, taught and assessed within the education system in first place. English language classes are generally approached as “subjects to be taught” at schools, and rather than focusing on finding ways of improving learners’ skills in the foreign language, the curriculum includes “topics to be covered” with a heavy focus on grammar and vocabulary.

This, of course, extends to assessment practices, and the cycle continues primarily with teaching and assessing grammar and vocabulary proficiency. Participants in Pearson’s report claim the heavy emphasis on teaching grammar and vocabulary, and not having enough opportunities to practice the language both inside and outside the classroom, as the three primary factors contributing to their lack of communication skills. If this was asked to Turkish learners, it’s highly likely that we would get the exact same three top reasons. The implication for educators here is very explicit: we must first revisit the definition of what “knowing a language is” and align our definition with our teaching and assessment methodology. What use is knowing a language without being able to communicate with it?

New opportunities needed for practice

Another clear implication for learners’ lack of opportunities to use the target language both in and outside the classroom is evident; teachers must refrain from dominating classroom discourse and instead create opportunities for learners to actively engage with the language. Recognizing common learning barriers in this context is crucial, as these barriers can significantly hinder students' ability to practice language skills effectively in corporate settings, professional development, and adult learning environments. Especially in a foreign language context, like in Turkey, this would gain even more importance for the students who lack opportunities to practice their target language in their daily lives.

Understanding different learning styles is essential in this process, as it allows teachers to design engagement strategies that accommodate visual, kinaesthetic, or auditory learning preferences, thus addressing the limitations and specific needs of individual learners. Teachers, who are reported to dominate 80% of class time with their own talk, have the primary responsibility for this issue. These teachers, which refers to the majority, should monitor themselves to ensure they are creating opportunities for active participation and language practice for their students.

Encouraging the learning process as an everyday habit

Students seem to need guidance for practicing the language not only inside but also outside the classroom to improve their proficiency, where external factors such as limited access to resources and environmental distractions can significantly hinder their ability to learn. Integrating technology into education and guiding students to continue their learning beyond classroom settings would undoubtedly be valuable advice. Language learning apps and especially social media can empower students to engage with the language in creative and meaningful ways, addressing extrinsic barriers by providing access to resources and support that overcome the lack of support from teachers or peers and environmental distractions.

Being able to function in a foreign language, such as negotiating, giving opinions, and making suggestions, were indicated as areas where the gap exists between what is needed and what students possess in language skills. Such a result would again require a shift towards more communicative and task-based language teaching approaches, giving opportunities for students to exercise these skills not only in professional but also in academic and social contexts.

Raising awareness among students about the benefits of language proficiency can be suggested as another implication that will also inspire them. Aligning educational curricula with real-life needs and raising awareness of both students and teachers about the rationale behind it is crucial for helping students set their own goals more accurately while their teachers guide them with realistic expectations.

Understanding motivational learning barriers

"I didn’t feel as if I was making progress" was one of the barriers participants indicated was stopping them from achieving greater proficiency, highlighting an emotional learning barrier that stems from internal challenges such as peer pressure and resistance to change. This gives another implication for assisting students to recognize and appreciate how much they have achieved in their learning process and how much more there is to achieve. Additionally, motivational barriers play a significant role, as they reflect the obstacles that arise from losing curiosity and desire for learning, leading to students missing classes or refusing to take courses. The Global Scale of English (GSE) is definitely a valuable tool to track learner progress by providing a concrete framework and by improving their confidence, thereby helping to overcome both emotional and motivational barriers.

In conclusion, while the list of implications for educators might be enhanced, the most significant suggestion lies in reconsidering our perception of language learning and proficiency. This shift in perspective will have a great impact on all aspects of language education, particularly teaching and assessment methodologies. Embracing this new understanding of language teaching will not only enhance the effectiveness of language education but also better prepare learners for real-world language use and interaction and better life conditions.
