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.

    How can gaming support language learning?

    By Jacqueline Martin

    Reading time: 5 minutes

    Academics and teachers have been writing about the benefits of using games in the language classroom for many years. Wright et al (1984), Lee Su Kim (1995), Ubermann (1998), Ersoz (2000), Yong Mei and Yu-Jin (2000) and Thi Thanh Huyen and Khuat Thi Thu Nga (2003) all pretty much agreed that games provide a useful and meaningful context for language use; encourage students to interact and communicate; can both challenge and reduce anxiety (as the emphasis is on the message, not the form); provide practice in all four skills; and help students to make and sustain the significant effort involved in learning a language.

    Kim and others have also noted that games can offer a welcome break from the usual routine of the language class. Playing a game after an intensive test or with over-excited students after break time can help re-engage learners instantly in your lesson, and you'll maximize your time with them.

    Lengeling and Malarcher (1997) took the list of potential benefits of games in the classroom even further.

    Affective

    • Games lower the affective filter
    • They encourage the creative and spontaneous use of language
    • They promote communicative competence
    • Games are both motivating and fun

    Cognitive

    • Games reinforce learning
    • They both review and extend learning
    • Games focus on grammar in a communicative manner

    Class dynamics

    • Games are extremely student-centered
    • The teacher acts only as a facilitator
    • Games build class cohesion
    • They can foster whole-class participation
    • Games promote healthy competition

    Adaptability

    • Games can be easily adjusted for age, level and interests
    • They utilize all four skills
    • Games require minimum preparation after the initial development stage

    It is important to bear in mind that when the above was written over 20 years ago, it was with reference mostly to more traditional games. But more recent evidence seems to indicate that the same principles apply. Some additional benefits cited by teachers I've spoken to are that:

    • Games could make language lessons less threatening for less confident pupils as their concern about getting sentence form wrong was reduced, and so their production greater.
    • Students learn more than just the language of the lesson when playing a game; they may learn instructional language through discussion or rules and sometimes negotiation skills and a lesson in cultural differences too.
    • Students can form a greater variety of emotional connections with language through playing games, for example acting out a word or seeing another student do so, or remembering a clue for a word.

    So, playing games can help students learn a language – but is just playing them enough? Some teachers like using games with less motivated classes who won't engage with straight practice activities and will willingly use key vocabulary and structures in a game, gaining much-needed practice without even realizing it. In today's language-learning context, though, is that a good thing?

    Motivating the unmotivated

    In recent years, much research has shown that students learn better when the intention or objective of the lesson is clear to them. In short, they understand what they're supposed to be learning and why and, when taking it to the next level, can assess their own learning and be actively involved in planning their next steps.

    Would knowing that the games they play are actually a way of doing some additional language practice make these students engage less? Opinion differs, and some discussion seems to center around the actual activity involved. Some games are thinly veiled group-work tasks, but other games that are at the right proficiency level (or slightly above) and take into account factors like cultural context, available time, learning topic and the classroom setting are generally considered to have a positive impact.

    Another major influence on improving motivation is the feedback a student receives, and this is something games can also support. Online games can provide richer simulated learning experiences and immediate feedback to students in a variety of ways.

    Above all, the main issue for the less motivated students is usually that they can't see why they need to learn English. Playing games not only simulates 'real' contexts but also helps them understand that they can accomplish a variety of tasks using English as a medium, which is motivational in itself.

    As teachers, there is a responsibility to explain how or why games will help students learn. This can equally motivate learners (or parents) who fear that playing games is just frivolous time-wasting. For example, informing even adult students that a simple hangman or hot seat game helps them improve spelling skills, gets their brains focused on recognizing the shape and structure of new words, and facilitates their learning of new vocabulary soon helps them see the value (Simpson 2011).

    Can games help learners acquire 21st-century skills?

    Maybe we can draw the conclusion that games can positively impact learning – but is that even enough? Today's teachers have to ensure not just that their students learn but that they acquire the skills they need for life and jobs in the 21st century. Can games help here too? This is a newer area of research, but evidence seems to indicate that games can help students learn a variety of important skills such as critical thinking skills, creativity, teamwork and good sportsmanship.

    These ideas were taken seriously by Robert Morris University Illinois, who offered an e-sports scholarship for the first time in 2014. They studied two groups of students – football players and gamers – and found that levels of competitiveness, perseverance, focus and determination were very similar. Both groups showed a similar desire to excel as part of a team. Both 'sports' required the team members to be detail-orientated, have good hand-eye coordination and have a strategic mind. The only difference was in the level of cardiovascular activity. Both groups received performance analysis and tactical advice from coaches and both subsequently made improvements.

    How many universities will start to offer these types of programs remains to be seen. Still, the idea that online competitive gaming can improve performance is being brought to the workplace too. Think about what virtual teams could learn from playing role-based collaborative games. Team members have set roles and clear and shared goals and have to work closely together to formulate an action plan to achieve them. Teamwork, skill, strategic thinking and communication are essential.

    All these are important skills for today's workplace, so maybe gaming can provide an opportunity to hone these in a lower-risk environment and improve business performance.

    These examples are clearly far from the norm, but they do seem to indicate that using gaming to support learning in the classroom is not a waste of time. When you get the right mix of gaming and learning, it develops a student's autonomous learning skills and encourages them to spend more time on task – both of which greatly impact learner outcomes.

    The role of English proficiency in a global organization

    By Samantha Ball
    Reading time: 4 minutes

    To compete in the modern business space, many organizations are shifting to a more global way of working.

    The COVID-19 pandemic accelerated digital transformation and globalization across industries but, as many businesses look now to sustaining future growth, the question is: what powers a successful, global organization?

    Why English proficiency is key to unlocking international success

    According to app’s 2022 Power Skills Survey, one of the biggest factors in effective workplace globalization is the use of English as a common language. The report states “Adopting a common language and ensuring that the entire workforce can access it has become more important than ever before.”

    It points to statistics from rising economies in Southeast Asia, showcasing the strength of English use and their respective booming industries:

    • In Indonesia, Southeast Asia’s largest economy in terms of GDP, the service sector employs nearly half of the country’s local workforce.
    • In Thailand, nearly 60% of the country’s GDP is generated by tourism and export-oriented production. Vietnam, one of APAC’s fastest-growing markets and a rising manufacturing powerhouse, counts the US among its top trading partners.
    • The Philippines’ business process outsourcing (BPO) sector, a key pillar of the country’s economy, employs 1.3 million people.

    The power of effective communication

    app’s 2022 Power Skills Survey is a drop in the ocean of reports hailing effective communication as one of the top factors to both personal and business success. Good communicators have been linked to higher performance in school, at work and in their personal lives. It is no surprise then that good communicators are highly sought after by talent recruiters.

    With many businesses moving to hiring outside of traditional location boundaries, more languages are inevitable in the workplace. So, can good communication transcend language barriers?

    As the statistics gathered by the Power Skills Survey show, there is evidence that sharing one common language, and therefore enabling more effective communication, can improve business opportunities, workforce growth and ultimately the economy. In the survey report, Norlida Azmi, Group Chief People Officer at Axiata, said:

    “Communication is a critical skill that sets the foundation for not only leadership competencies, such as people management and coalition building, but also for wider and effective stakeholder management in the ecosystem – communicating with our shareholders, customers and the communities that we operate in.”

    English: the official language of business

    While communication for globalization can look different for different markets, the English language is recognized as the prevailing choice for multinational companies. The Harvard Business Review says:

    “The need to tightly coordinate tasks and work with customers and partners worldwide has accelerated the move toward English as the official language of business.”

    So, with businesses now fighting to grow in a global marketplace, unlocking the power of the English language is crucial to success.

    Assessing English proficiency within your organization

    The survey shows that many organizations have work to do in this area, even if they view strong English proficiency as extremely important to their roles. It details the current state of assessing candidates’ English language proficiency and the percentage of organizations that have strategies in place to upskill their employees English proficiency. Both leave room for improvement.

    According to the survey, the number one way talent acquisition managers test English language skills is at the interview (58%), although 37% aren't measuring English language skills at all. This can be problematic later down the line, as not all four language skills (reading, writing, speaking and listening) will be accurately represented in an interview.

    Meanwhile, 27% of businesses use computer-based tests and 14% use paper-based tests to assess English language proficiency. By getting standardized test results, talent managers can more accurately assess if candidates’ English proficiency is suitable for the role, making for more confident and successful hires.

    Strategies for English upskilling

    Talent managers can also pass on these insights to learning and development managers to help them implement effective English language upskilling programs. While this investment can empower employees to perform better in their new role, it may also improve employee retention and even lead to succession and impact business growth.

    Whether organizations choose to hire new talent with higher levels of English proficiency or invest in learning and development programs to build their employees’ language skills, there are tools available to help.
