Listening Gapfill Challenge: Thinking about decoding issues for our learners.

In this post, I’ll share an activity I’ve used in many an English Language teacher training session - the gapfill challenge. I’ve used it with pre-service teachers on CELTA or Cert TESOLs, and in-service training or higher quals like Delta and Dip TESOL.

Listening issues: Learner difficulties with unscripted speech.

Listening in an additional language poses a major difficulty to language learners. In this post, Shaun Sweeney reports on a small-scale research project investigating what makes authentic speech so difficult for our learners.

Get Dip Ready

A while back we ran a series of open webinars aimed at teachers preparing to take an advanced TESOL qualification such as the Trinity Dip TESOL or Cambridge Delta.

Rachel Tsateri: Self-observation as a tool for professional development

…The answer is, if you take a scientific approach, it's easier than you think. First, we don't need to start with evaluating our actions.

Trinity Dip TESOL v Cambridge DELTA. Which should I choose?

Taking the lesson to task

Interested in making your lessons more task-based? Thinking of doing a task-based lesson on your Dip TESOL or DELTA course?

Task-based lessons are a great way to ensure there is genuine communication and a real focus on meaningful interaction in your lessons.

Dancing police go corona-viral!

This is a materials-light lesson that can be run 100% synchronously or asynchronously or a bit of both. And the feel-good factor when all your students are showing each other how to do their dance crazes at the end is hard to beat. Just the thing for a cold February day.

What Specialism Should I Choose for my DELTA Module 3 Assignment?

As tutors, this is a question we’re often asked when people are considering their Cambridge DELTA Module 3 course applications. The answer really depends on your situation and what you’re looking to get out of the qualification.
