Research has shown that automated scoring can give more reliable and objective results than human examiners when evaluating a person’s mastery of English. This is because an automated scoring system is impartial, unlike humans, who can be influenced by irrelevant factors such as a test taker’s appearance or body language. Additionally, automated scoring treats regional accents equally, unlike human examiners who may favor accents they are more familiar with. Automated scoring also allows individual features of a spoken or written test question response to be analyzed independent of one another, so that a weakness in one area of language does not affect the scoring of other areas.

PTE Academic was created in response to the demand for a more accurate, objective, secure and relevant test of English. Our automated scoring system is a central feature of the test, and vital to ensuring the delivery of accurate, objective and relevant results – no matter who the test-taker is or where the test is taken.

Development and validation of the scoring system to ensure accuracy

PTE Academic’s automated scoring system was developed after extensive research and field testing. A prototype test was developed and administered to a sample of more than 10,000 test takers from 158 different countries, speaking 126 different native languages. This data was collected and used to train the automated scoring engines for both the written and spoken PTE Academic items.

To do this, multiple trained human markers assess each answer. Those results are used as the training material for machine learning algorithms, similar to those used by systems like Google Search or Apple’s Siri. The model makes initial guesses as to the scores each response should get, then consults the actual scores to see well how it did, adjusts itself in a few directions, then goes through the training set over and over again, adjusting and improving until it arrives at a maximally correct solution – a solution that ideally gets very close to predicting the set of human ratings.

Once trained up and performing at a high level, this model is used as a marking algorithm, able to score new responses just like human markers would. Correlations between scores given by this system and trained human markers are quite high. The standard error of measurement between Pearson’s system and a human rater is less than that between one human rater and another – in other words, the machine scores are more accurate than those given by a pair of human raters, because much of the bias and unreliability has been squeezed out of them. In general, you can think of a machine scoring system as one that takes the best stuff out of human ratings, then acts like an idealized human marker.

Pearson conducts scoring validation studies to ensure that the machine scores are consistently comparable to ratings given by skilled human raters. Here, a new set of test-taker responses (never seen by the machine) are scored by both human raters and by the automated scoring system. Research has demonstrated that the automated scoring technology underlying PTE Academic produces scores comparable to those obtained from careful human experts. This means that the automated system “acts” like a human rater when assessing test takers’ language skills, but does so with a machine's precision, consistency and objectivity.

Scoring speaking responses with Pearson’s Ordinate technology

The spoken portion of PTE Academic is automatically scored using Pearson’s Ordinate technology. Ordinate technology results from years of research in speech recognition, statistical modeling, linguistics and testing theory. The technology uses a proprietary speech processing system that is specifically designed to analyze and automatically score speech from fluent and second-language English speakers. The Ordinate scoring system collects hundreds of pieces of information from the test takers’ spoken responses in addition to just the words, such as pace, timing and rhythm, as well as the power of their voice, emphasis, intonation and accuracy of pronunciation. It is trained to recognize even somewhat mispronounced words, and quickly evaluates the content, relevance and coherence of the response. In particular, the meaning of the spoken response is evaluated, making it possible for these models to assess whether or not what was said deserves a high score.

Scoring writing responses with Intelligent Essay Assessor™ (IEA)

The written portion of PTE Academic is scored using the Intelligent Essay Assessor™ (IEA), an automated scoring tool powered by Pearson’s state-of-the-art Knowledge Analysis Technologies™ (KAT) engine. Based on more than 20 years of research and development, the KAT engine automatically evaluates the meaning of text, such as an essay written by a student in response to a particular prompt. The KAT engine evaluates writing as accurately as skilled human raters using a proprietary application of the mathematical approach known as Latent Semantic Analysis (LSA). LSA evaluates the meaning of language by analyzing large bodies of relevant text and their meanings. Therefore, using LSA, the KAT engine can understand the meaning of text much like a human.

What aspects of English does PTE Academic assess?

“Sharing a story with your child is one of the most incredible things you can do for them.” – The Book Trust.

Research shows that getting kids reading at home can increase their reading ability at school – and improve their overall well-being. Parents and guardians can make a big difference. But how can teachers encourage parents to get their children to read more at home? We explore some strategies you can use.

Tell parents about the benefits

Reading can give children a break from technology-centered activities. It can help them to relax and unwind; reading a book can make children laugh and feel happier! Through hearing stories, children are also exposed to a rich and broad vocabulary.

“It is important for teachers to establish contact with parents as much as possible and give very clear guidelines on the benefits of reading, and how they can create a reading routine and help their children read at home,” says Kasia Janitz-De La Rue, Product Development Director at Pearson.

So, encourage parents to find time for a reading routine. Just before bedtime is a great time, as a nightly reading routine is associated with improved sleep in children.

Give parents practical ideas for reading strategies

Encourage parents to read with and not to their child. It doesn’t matter how long they set aside to read – just 10 minutes of quality reading time can make a big difference.

Here are a few tips concrete reading tips for teachers to share with parents:

• Ask children lots of questions while reading.
• Use encouragement and praise to keep children engaged. Saying things like “what fantastic ideas” or “you thought so carefully about that, what might happen now?" will keep their minds working.
• Use their past experiences to talk about what’s being read. Things like “have you learnt about…at school?” or “do you remember when we watched…and found out about…?” are good conversation starters.
• Tune in and listen to children, and be curious about their interests. “I didn’t know you knew so much about…” or “I love reading stories about…with you,” are good phrases to keep in mind.

It’s also a great idea to share online resources with parents. You can also suggest that parents look up read-aloud YouTube videos featuring authors, teachers or librarians reading their favorite stories. This way, children can watch and listen as often as they like.

Recommend graded readers

Graded readers are books that use language in line with a child‘s learning level. They can help children build confidence, and help slowly expose them to authentic reading levels.

Encourage parents to identify what genre their child is interested in and show them the readers available. Each time parents see their children move up a level, they’re sure to see their children’s love for reading grow.

Suggest before, during, and after reading activities

Before reading

Parents can take turns with their children to predict what the story is about – or what will happen next. Here is an activity teachers may suggest they try:

“Start with the cover of the book and the blurb on the back cover. Reveal the cover slowly to ask the child what they can see. Ask them to guess what is on the cover. Once they have seen the cover, ask them questions about the images on the cover – who, what, why, where and how?”

While reading

Remind parents to focus on their children’s reading comprehension by using strategies like prediction, questioning, clarifying, and summarising. Teachers can ask parents to:

• check ideas and understanding as the child reads: ‘So, you think that….’ ‘Did you expect…to happen?’ ‘Why do you think that happened?’
• use the pictures in the book to help with comprehension
• describe what is happening and talk about the characters.

After reading

Don’t forget: parents can continue to explore the book’s topic once reading time is done! A few ideas to share with parents include:

• organising a puppet show for family members and siblings after making puppets of the characters in the book
• having children draw a picture of their favorite character or their favorite page in the story
• encouraging children to express their opinion on the book.

How can we help children (and ourselves) deal with turbulent situations?

As humans, we are programmed to position ourselves according to the constants around us: people, structures and boundaries. When those constants shift, it can be unsettling for adults and children.

Sometimes we find ourselves in unprecedented situations, and we each have our own approach to managing things. If you feel confused and without direction because of a turbulent situation, please know that that is okay.

We’ll look today at why that is, to help us understand ourselves a little more and why these simple mindfulness activities can help us navigate it.

What causes social stress?

There may be many reasons for feeling stressed in life, but during turbulent times in society, it is often due to not feeling safe.

Something in our environment is alerting our survival instinct. This makes our brains produce stress hormones, which get us ready to fight the threat, run from it, or freeze until it’s gone away.

The threat might be to our physical or even social survival – and the two are linked. Things can feel even scarier when we also feel isolated from our social group, which keeps us protected from that threat.

Human beings are social by nature. We live and work in communities, we connect through love and empathy and we protect each other. There’s truth to the saying “there’s safety in numbers”.

But it’s not just about safety. We also define ourselves by comparing ourselves to others and working out what we are not.

Research has found that we identify deeply with our role in society and the ‘pack’ to which we belong. This holds deep ties with our sense of safety, contentment and self-esteem. If the boundaries by which we define and position ourselves have shifted or continue to shift, we will feel unsafe, threatened and therefore stressed.

Are children affected by social stress in the same way?

If we then apply this to children, the constants to whom they look for security are the adults in their life. If the adults are behaving differently, the children will feel a shift and feel unsafe and stressed too. If they don’t have their friends alongside them for social positioning, this too can lead to them feeling confused and uncertain.

Here are some key ways we can help:

Communicating and listening

Children may often lack the language to express what they are feeling, or even to recognize it themselves. Therefore, we must offer ways to help them make sense of the world around them, to help them feel safe and to help express their concerns.

Communication provides the necessary social interaction and models for them on how to handle the new situation. It firms up their boundaries, and provides a safe space where they feel listened to and acknowledged and this, in turn, helps diffuse their stress.

The activity below is a lovely way to invite children to express any worry they might be feeling, mindfully and with support – and give them something to do with their feelings. It also has the benefit of helping them breathe fully and slowly, which will calm down their nervous system.

Breath activity: Worry bubbles

1. Sit together and invite your child to put their palms together.
2. Invite them to take a big breath in. As they breathe in, they can draw their palms further and further apart, spreading their fingers as they imagine blowing up a big bubble between their hands.
3. Invite them to whisper a worry into the bubble.
4. Invite them to blow the breath out nice and slowly. As they breathe out, they can imagine blowing the bubble (and the worry) away with a big sigh.
5. Twinkle the fingers back down to the lap, and start again, either with the same worry or a new one

Helping them find a safety anchor inside themselves

By helping children focus on breathing, we can teach them that even if things feel wobbly around them, their breath is always there. The act of focusing on the breath also helps settle the fight or flight branch of their nervous system into a calmer, more balanced state.

Breath Activity: Counting breaths

1. Invite your child to sit with you.
2. Invite them to place their hands on their tummy and breathe in slowly so they push into their hands, counting slowly up to four.
3. As they breathe out, invite them to count up to six, as they slowly empty the belly and their hands lower back down.
4. Continue until they feel calmer. You can do this every morning or evening to help sustain balance. With younger children, they might like a teddy on their tummy to push up and down!

These two activities can be lovely daily practices to try and provide some safety and structure to your child or students’ mental health right now. They are also enjoyable activities to try for yourself – you may like to increase the in and out count of the breath a little bit for an adult breath.
