AI and teacher training

Who can tell where a blog post might lead? Over six years ago I wrote about adaptive professional development for teachers. I imagined the possibility of bite-sized, personalized CPD material. Now my vision is becoming real.

For the last two years, I have been working with a start-up that has been using AI to generate text using GPT-3 large language models. GPT-3 has recently been in the news because of the phenomenal success of the newly released ChatGPT. The technology certainly has a wow factor, but it has been around for a while now. ChatGPT can generate texts of various genres on any topic (with a few exceptions like current affairs) and the results are impressive. Imagine, then, how much more impressive the results can be when the kind of text is limited by genre and topic, allowing the software to be trained much more reliably.

This is what we have been working on. We took as our training corpus a huge collection of English language teaching teacher development texts that we could access online: blogs from all the major publishers, personal blogs, transcriptions from recorded conference presentations and webinars, magazine articles directed at teachers, along with books from publishers such as DELTA and Pavilion ELT, etc. We identified topics that seemed to be of current interest and asked our AI to generate blog posts. Later, we were able to get suggestions of topics from the software itself.

We then contacted a number of teachers and trainers who contribute to the publishers’ blogs and contracted them, first, to act as human trainers for the software, and, second, to agree to their names being used as the ‘authors’ of the blog posts we generated. In one or two cases, the authors thought that they had actually written the posts themselves! Next we submitted these posts to the marketing departments of the publishers (who run the blogs). Over twenty were submitted in this way, including:

• What do teachers need to know about teaching 21^st century skills in the English classroom?
• 5 top ways of improving the well-being of English teachers
• Teaching leadership skills in the primary English classroom
• How can we promote eco-literacy in the English classroom?
• My 10 favourite apps for English language learners

We couldn’t, of course, tell the companies that AI had been used to write the copy, but once we were sure that nobody had ever spotted the true authorship of this material, we were ready to move to the next stage of the project. We approached the marketing executives of two publishers and showed how we could generate teacher development material at a fraction of the current cost and in a fraction of the time. Partnerships were quickly signed.

Blog posts were just the beginning. We knew that we could use the same technology to produce webinar scripts, using learning design insights to optimise the webinars. The challenge we faced was that webinars need a presenter. We experimented with using animations, but feedback indicated that participants like to see a face. This is eminently doable, using our contracted authors and deep fake technology, but costs are still prohibitive. It remains cheaper and easier to use our authors delivering the scripts we have generated. This will no doubt change before too long.

The next obvious step was to personalize the development material. Large publishers collect huge amounts of data about visitors to their sites using embedded pixels. It is also relatively cheap and easy to triangulate this data with information from the customer databases and from activity on social media (especially Facebook). We know what kinds of classes people teach, and we know which aspects of teacher development they are interested in.

Publishers have long been interested in personalizing marketing material, and the possibility of extending this to the delivery of real development content is clearly exciting. (See below an email I received this week from the good folks at OUP marketing.)

Earlier this year one of our publishing partners began sending links to personalized materials of the kind we were able to produce with AI. The experiment was such a success that we have already taken it one stage further.

One of the most important clients of our main publishing partner employs hundreds of teachers to deliver online English classes using courseware that has been tailored to the needs of the institution. With so many freelance teachers working for them, along with high turnover of staff, there is inevitably a pressing need for teacher training to ensure optimal delivery. Since the classes are all online, it is possible to capture precisely what is going on. Using an AI-driven tool that was inspired by the Visible Classroom app (informed by the work of John Hattie), we can identify the developmental needs of the teachers. What kinds of activities are they using? How well do they exploit the functionalities of the platform? What can be said about the quality of their teacher talk? We combine this data with everything else and our proprietary algorithms determine what kinds of training materials each teacher receives. It doesn’t stop there. We can also now evaluate the effectiveness of these materials by analysing the learning outcomes of the students.

Teaching efficacy can by massively increased, whilst the training budget of the institution can be slashed. If all goes well, there will be no further need for teacher trainers at all. We won’t be stopping there. If results such as these can be achieved in teacher training, there’s no reason why the same technology cannot be leveraged for the teaching itself. Most of our partner’s teaching and testing materials are now quickly and very cheaply generated using GPT-3.5. If you want to see how this is done, check out the work of edugo.AI (a free trial is available) which can generate gapfills and comprehension test questions in a flash. As for replacing the teachers, we’re getting there. For the time being, though, it’s more cost-effective to use freelancers and to train them up.
