Automated assessment, including the use of Artificial Intelligence (AI), is one of the latest education tech solutions. It speeds up exam marking times, removes human biases, and is as accurate and at least as reliable as human examiners. As innovations go, this one is a real game-changer for teachers and students.?
However, it has understandably been met with many questions and sometimes skepticism in the ELT community ¨C can computers?really?mark speaking and writing exams accurately??
The answer is a resounding yes. Students from all parts of the world already take AI-graded tests.??and?Versant?tests ¨C for example ¨C provide unbiased, fair and fast automated scoring for speaking and writing exams ¨C irrespective of where the test takers live, or what their accent or gender is.?
This article will explain the main processes involved in AI automated scoring and make the point that AI technologies are built on the foundations of consistent expert human judgments. So, let¡¯s clear up the confusion around automated scoring and AI and look into how it can help teachers and students alike.?
First of all, let¡¯s distinguish between traditional automated scoring and AI. When we talk about automated scoring, generally, we mean scoring items that are either multiple-choice or cloze items. You may have to reorder sentences, choose from a drop-down list, insert a missing word- that sort of thing. These question types are designed to test particular skills and automated scoring ensures that they can be marked quickly and accurately every time.
While automatically scored items like these can be used to assess receptive skills such as listening and reading comprehension, they cannot mark the productive skills of writing and speaking. Every student's response in writing and speaking items will be different, so how can computers mark them?
This is where AI comes in.?
We hear a lot about how AI is increasingly being used in areas where there is a need to deal with large amounts of unstructured data, effectively and 100% accurately ¨C like in medical diagnostics, for example. In language testing, AI uses specialized computer software to grade written and oral tests.?
The first step is to build an acoustic model for each language that can recognize speech and convert it into waveforms and text. While this technology used to be very unusual, most of our smartphones can do this now.?
These acoustic models are then trained to score every single prompt or item on a test. We do this by using human expert raters to score the items first, using double marking. They score hundreds of oral responses for each item, and these ¡®Standards¡¯ are then used to train the engine.?
Next, we validate the trained engine by feeding in many more human-marked items, and check that the machine scores are very highly correlated to the human scores. If this doesn¡¯t happen for any item, we remove it, as it must match the standard set by human markers. We expect a correlation of between .95-.99. That means that tests will be marked between 95-99% exactly the same as human-marked samples.?
This is incredibly high compared to the reliability of human-marked speaking tests. In essence, we use a group of highly expert human raters to train the AI engine, and then their standard is replicated time after time.??
Our AI writing scoring uses a technology called . LSA is a natural language processing technique that can analyze and score writing, based on the meaning behind words ¨C and not just their superficial characteristics.?
Similarly to our speech recognition acoustic models, we first establish a language-specific text recognition model. We feed a large amount of text into the system, and LSA uses artificial intelligence to learn the patterns of how words relate to each other and are used in, for example, the English language.?
Once the language model has been established, we train the engine to score every written item on a test. As in speaking items, we do this by using human expert raters to score the items first, using double marking. They score many hundreds of written responses for each item, and these ¡®Standards¡¯ are then used to train the engine. We then validate the trained engine by feeding in many more human-marked items, and check that the machine scores are very highly correlated to the human scores.?
The benchmark is always the expert human scores. If our AI system doesn¡¯t closely match the scores given by human markers, we remove the item, as it is essential to match the standard set by human markers.
One of the challenges human markers face in scoring speaking and written items is assessing many traits on a single item. For example, when assessing and scoring speaking, they may need to give separate scores for content, fluency and pronunciation.?
In written responses, markers may need to score a piece of writing for vocabulary, style and grammar. Effectively, they may need to mark every single item at least three times, maybe more. However, once we have trained the AI systems on every trait score in speaking and writing, they can then mark items on any number of traits instantaneously ¨C and without error.?
A fundamental premise for any test is that no advantage or disadvantage should be given to any candidate. In other words, there should be no positive or negative bias. This can be very difficult to achieve in human-marked speaking and written assessments. In fact, candidates often feel they may have received a different score if someone else had heard them or read their work.
Our AI systems eradicate the issue of bias. This is done by ensuring our speaking and writing AI systems are trained on an extensive range of human accents and writing types.?
We don¡¯t want perfect native-speaking accents or writing styles to train our engines. We use representative non-native samples from across the world. When we initially set up our AI systems for speaking and writing scoring, we trialed our items and trained our engines using millions of student responses. We continue to do this now as new items are developed.
There is nothing wrong with hand-marking homework tests and exams. In fact, it is essential for teachers to get to know their students and provide personal feedback and advice. However, manually correcting hundreds of tests, daily or weekly, can be repetitive, time-consuming, not always reliable and takes time away from working alongside students in the classroom. The use of AI in formative and summative assessments can increase assessed practice time for students and reduce the marking load for teachers.
Language learning takes time, lots of time to progress to high levels of proficiency. The blended use of AI can:
address the increasing importance of?formative assessment?to drive personalized learning and diagnostic assessment feedback?
allow students to practice and get instant feedback inside and outside of allocated teaching time
address the issue of teacher workload
create a virtuous combination between humans and machines, taking advantage of what humans do best and what machines do best.?
provide fair, fast and unbiased summative assessment scores in high-stakes testing.
We hope this article has answered a few burning questions about how AI is used to assess speaking and writing in our language tests. An interesting quote from Fei-Fei Li, Chief scientist at Google and Stanford Professor describes AI like this:
¡°I often tell my students not to be misled by the name ¡®artificial intelligence¡¯ ¡ª there is nothing artificial about it; A.I. is made by humans, intended to behave [like] humans and, ultimately, to impact human lives and human society.¡±
AI in formative and summative assessments will never replace the role of teachers. AI will support teachers, provide endless opportunities for students to improve, and provide a solution to slow, unreliable and often unfair high-stakes assessments.
At ÃÛÌÒapp, we have developed a range of assessments using AI technology.
The Versant tests are a great tool to help establish language proficiency benchmarks in any school, organization or business. They are specifically designed for placement tests to determine the appropriate level for the learner.

When you¡¯re teaching English to young learners, you might find that there are a few students in your class who are struggling. But sometimes it can be hard to tell why. Is it because their language level is low? Or are they finding classroom work difficult because of a general cognitive difference, like dyslexia??
Do you ever find it hard to keep students focused and on task? Young learners get easily distracted and it can be hard to find ways to keep them engaged.
So what can we do to get, and more importantly, keep our students¡¯ attention? Here are our five top tips.
Young learners have relatively short attention spans. In the classroom, it is rare to have the whole class fully engaged in something for a long time, since the children will have different interests and levels, so it is essential to plan a number of activities for each lesson.
The more variety you can include in the activities and tasks you plan, the easier it is to provide something enjoyable and relevant for each child. Choose short tasks and try to have a couple of extra activities up your sleeve if something you planned doesn¡¯t work well. However, don¡¯t worry if you don¡¯t have time to do them all ¨C you can always save them for a future lesson.
Another way of keeping students engaged is to mix up the classroom dynamics, having a combination of individual heads-down work, pair work, group work, and whole class discussions or games. When planning your lesson, consider how your students might feel at each stage. After doing some reading or quiet work, students may start to become restless, and this is the ideal time to get them up and moving about.
While you are in class, pay close attention to the mood of the class. When you sense that students are becoming distracted or bored, change the dynamics of the activity.
Ever notice that students become lethargic and show a lack of interest? Why not try introducing brain breaks at strategic points in your lessons? Brain breaks are short physical activities or games designed to get the blood flowing and to re-energize students to help them get ready for learning. They range from short activities that last a couple of minutes, to longer breaks that may be suitable if your lessons last more than an hour.
We can vary different aspects of the lesson using the previous strategies, but one thing that rarely changes is the role of the teacher! One way of keeping students involved is by giving them more responsibility and allowing them to take a more active role in their learning.
Peer teaching completely changes the classroom dynamic and has students teach their peers while you take a step back. For primary classes, ask one or two students to take charge of a ready-made activity, e.g. one from your course book. They should give instructions, demonstrate, monitor as necessary, and check answers.
When students are used to doing this, you can start to have them work in pairs or small groups to plan their own activities to use in class.
Of course, nobody is perfect and there will be times when you lose students¡¯ attention and they are not on task. For these occasions, you can use a wealth of classroom management strategies to regain the class's attention. Here are a few techniques:
Finally, if we want our students to be motivated and engaged in our lessons, we must show enthusiasm for what we are teaching. The more lively and animated you are about the lesson, the more the students will want to join you and learn.
There is a strong link between well-being and friendship, which is just as accurate for children as it is for adults. that children with stable friendships are happier, more able to cope with stress, and have higher self-esteem. Moreover, too, and children who experience friendship adjust more easily to school and perform better academically. School friendships are also a valuable way of learning social skills like sharing, resolving conflict, and engaging with peers positively.
Having friends is an important part of school life, and teachers can play a significant role in creating a positive classroom culture and helping children and young people to form friendships. How can you promote friendships between your students? Here are some ideas:
If there is an example of a good friendship in a book you are reading with students or in your lesson materials, draw your students¡¯ attention to it. For instance, The Jungle Book is an excellent example of a story about friendship. Encourage your students to think critically about the friendships that they read about. You can ask questions like:
By discussing friendship regularly in the classroom, your students will learn about the behavior and characteristics of being a good friend.
You can create lots of opportunities for students to build friendships with one another during class time. Design activities that call for pair or group work, and include at least one or two in every lesson. Focusing on a common goal or problem is a great way to encourage your students to bond with one another.?As a bonus, this collaborative way of working promotes important 21st century skills like communication and problem-solving.
Another way of promoting friendships between different groups of students is moving them around. Adjust your seating plan regularly to ensure that all your students interact with and work alongside different classmates, to promote positive, friendly classroom vibes.
Friendship is a social skill that children need to learn ¨C and you can help by teaching them. Be explicit about exactly what you expect from them. Saying, ¡°Be kind¡± is an abstract, vague concept that children might struggle to put into practice. Instead, give them concrete examples of behavior, such as:
When you see a student engaging in these behaviors, draw attention to them and praise them.
But to really convey the importance of school friendships and kind behavior, it¡¯s not enough to tell them. As the teacher, you must model the behavior you¡¯d like to see in your students. Be consistently positive and upbeat in your interactions with students, thank your learners when they offer help with something, and try to refrain from sounding impatient (even when you are!). All these steps will help to build a positive classroom culture where students feel secure, supported and happy.
Conflict is an inevitable part of school life, but you can help students to navigate arguments and other difficult situations in the classroom. If two students argue, you can help them to resolve it with the following steps:
Following these simple steps teaches children a framework for resolving conflict and gives them the tools to process strong emotions.
An excellent way to promote a positive classroom culture is to do friendship-focused activities with your students:
You could do a Venn diagram activity, where students work in pairs to discuss and write down things they have in common and areas of difference. It¡¯s good to pair students who don¡¯t spend much time together for this activity.
Another positive activity is a 'Honey Roast'. Give students enough squares of paper to have one for each of their classmates. Get them to write their classmates¡¯ names on the paper, and then, on the other side, write down a compliment or something they like about that person, for example, ¡°I like your handwriting¡±, or ¡°You always use kind words¡±. Collect the pieces of paper and read out some nice examples to the class. Alternatively, give them directly to the students to read to themselves.
