Hi @deefree I totally agree with you about the importance of guiding students step-by-step and demonstrating the value of a resource/website with concrete examples and applications, and this something you will hopefully notice about this course. By the way, we will not focus on COCA but if you are accessing it via https://www.english-corpora.org/, I am more than happy to answer any specific questions you might have. I have an account and have used it a bit in the past, so I can guide you with the interface a little. Concepts we will cover on the course e.g. concordancing, collocations, n-grams, etc. are transferrable to other corpus resources, but there is always the element of understanding a different interface and the types of queries it allows.
