Anyone following my blog will know that CELTA took over my life in August last year (2014), and will continue to dominate until the same time this year (2015). I’ve been building this list in my head for a while, and it’s finally time to get it onto the blog.
It’s arranged into categories, with subtitles and topics in bold to help you navigate. There’s a lot here, so just use the bits you need as you need them rather than trying to look at all of them – if not, you’ll end up being overwhelmed!
A quick way to find what you need it to press CTRL + F (CMD + F on a Mac) and type a key word connected to what you’re struggling with, like ‘TTT’, ‘instructions’ or ‘writing’ – this will take you straight to the relevant section.
Please let me know if any of the links are broken so I can update them, and feel free to add suggestions to the comments. I also plan to add to it as I write/find more posts.
Before the course
CELTA is a very intensive experience, and it’s important to know what you’re getting yourself into. Take a look at these to give you an idea of what to expect.
Cambridge English has a 30-minute webinar called The Ultimate Guide to CELTA which details different types of CELTA and tells you what to expect from the course. (Thanks to Viacheslav Kushnir for telling me about this)
CELTA diaries is a series of videos following two trainees taking the course at International House Belfast. IH London have some helpful tips for trainees. Nicky Salmon tells you How to survive a CELTA course, with tips from trainers and past trainees.
Giulia wrote about her experience on the course, reflecting on the positives and negatives, and Seth Newsome did the same with links to other posts he wrote about the process of doing the CELTA if you’d like a bit more depth. Rachel Daw wrote a week by week diary of her course, showing you what it’s like in depth: one MTW TF, two, three, four. Anne Hendler was interviewed each week by Matthew Noble, himself a CELTA tutor, on his blog: before the course, week one, week two, week three, after the course.
If you’re still not sure whether to do the course or not, Chia Suan Chong, a CELTA trainer, describes 10 things she likes about the CELTA, all of which I agree with.
Adam Simpson recommends 10 books to read before you start your CELTA. While you’re unlikely to get through all of them (due to the expense if nothing else!) I’d definitely recommend getting copies of either 1 or 2, plus 3, and possibly also 6. Another book that you might find useful is the Ultimate Guide to CELTA by Amanda Momeni and Emma Jones which is available as an ebook (thanks for recommending this Helen Strong).
Martin Sketchley tells you how to prepare for the CELTA in 9 easy steps, with advice about choosing a centre, things to do before the course and advice about working with your peers.
It’s particularly important to build your language awareness as much as possible before the course. Jo Gakonga has webinars on grammar for language teachers (30 minutes) and the present perfect for language teachers (42 minutes) – free samples of the introductory grammar course on Jo’s site. Jeff Mohamed’s grammar development course is recommended by some centres (for a very light version of this, Rachel Daw talks about 10 things she learnt from it when preparing for her CELTA). If you’re not sure about parts of speech in English (e.g. verbs, nouns etc), Pass the CELTA have an introduction to them. ELT concourse has a pretty comprehensive set of guides to various aspects of English grammar.
Another area that people often find overwhelming is the amount of terminology thrown at them. ELT Concourse helps you out by introducing some of it. I’ve put together a Quizlet class with most of the terminology you might come across (though remember the same thing might have different names in different places!) If you’ve never used Quizlet, here’s an introduction to it.
Brushing up on your technology skills could also help you out. You’re going to spend a lot of time in front of a computer, and every timesaver you can learn will make a difference. Regardless of how confident a Word user you are, it’s worth checking out my friend Liz Broomfield’s very clear posts about making the most of Word. She uses Word for Windows. If you have a Mac and can’t work it out, Google it first, then ask me and I’ll try to help – I have Microsoft Office 2008 for Mac.
If you’re planning to make flashcards, the quickest and easiest way is with Powerpoint rather than Word. Here’s are two beginner’s guides: a 17-minute video or a more in-depth pdf. One useful trick is printing handouts with 6 slides per page.
Keyboard shortcuts save a lot of time in the long run. These are 100 for Windows and some for Mac too. If you’ve got a long time before your CELTA, working on your touch typing will help you now and later. On a side note, set up a filing system on your computer and start naming files with lots of detail in the file name so you can find things easily in the future. “Document 1.docx” won’t help you, but “Personality adjectives and definitions NEF Pre-Int SB p6 and SB p145 U1B.docx” will. I always try to include the book, chapter and page numbers so I can use the search function to find things again quickly in the future.
Finally, for those of you thinking about trying to get a Pass A (the highest grade, which 3-5% of trainees get – I got a Pass B), here’s a report from someone who got one, along with the following very important advice which I completely agree with:
If you set up your goal as “I’m gonna gits me an A!” then, well, it’s a worthy goal and all, but you’ll probably give yourself an ulcer, and stress so much about whether you’re doing enough or doing well enough that your freaky-outy stress will cause you to lose focus and actually do worse. Don’t look for a magic bullet or secret formula – there is none, and trying to guess at the magical combination of factors that leads to an A will just cause you to get even more freaky-outy. Always remember that it’s not a competition, so if you see someone who seems to be doing better than you, hey, you’re in it for four weeks with that person and you are quite possibly friendly with them – you are not in a race. There is not just one gold medal. Their good work does not mean you’ll get edged out for the one top spot, because there is no “one” top spot.
By the way, when I did my CELTA, one of my fellow trainees got a Pass A with no prior teaching experience, so it is possible! However, in the courses I’ve tutored on so far, I’ve yet to see an A candidate.
How to approach lesson planning: I wrote this post to help you manage your time when planning on CELTA and try to avoid the ‘But finding the materials and making them look pretty is so much more fun than filling in all those tedious forms’ trap. The Cambridge CELTA blog offers an alternative way to manage the planning process.
Nicky Salmon, a CELTA trainer, tells you how to write CELTA lesson plans to make the documents as useful as possible for you and your trainer, so that you’re ready to give your students the best possible lesson.
The ELT Concourse guide to lesson planning covers aims, procedure, staging and a useful checklist of things to consider when planning. They also show examples of present-practice-produce and test-teach-test lessons, along with a guide to helping you decide between these two possible ways of staging a lesson (there are many more!). Pete at ELT Planning lists lots of different ways of staging your lessons (though only the names) and explains why it’s been important to him in his post-CELTA career. Later he put together a post with a breakdown of how to stage different lessons, covering most (all?) of the main types of lessons you may teach on CELTA, both language and skills. He’s also got 12 tips for writing lesson plans, not all of which apply to CELTA-level courses, but which are still useful.
Timing your elementary classes is a post I wrote in response to questions from my trainees about how to allocate timing when planning. Many of the points in it apply to intermediate classes too. Jonny Ingham also has a guide to timing your lessons.
Jo Gakonga has three webinars connected to lesson planning:
When writing aims, it can be useful to consider how SMART they are, as this will help you to know when and if you’ve achieved them – Andriy Ruzhynskiy shows you how to do this in a 10-minute webinar.
It’s important to provide a clear context for any lesson, whether it’s language or skills. Barbara Sakamoto explains why. ELT Concourse gives an example of context in action.
If you decide to create your own materials for your lesson, here are a few tips from the Oxford University Press blog. Adam Simpson talks about 6 things that can go wrong when making a worksheet and how to avoid them.
For more depth, Mike Cattlin, an experienced CELTA and Delta trainer has written an e-book called The Art of Lesson Planning.
Finally, if you’re getting stressed before your lesson, the Cambridge CELTA blog has some great tips on overcoming observation anxiety.
Classroom management and activity set-up
Standing at the front of a classroom can be a scary prospect. If teacher presence is a problem for you, the Times Educational Supplement can help you get the students’ attention. These tips from Fernando Guarany could also help improve your confidence as a teacher.
Other people have the opposite problem and talk way too much. Jo Gakonga has a webinar on teacher talk and language grading (12 minutes). Here are some ways to become aware of excessive TTT (teacher talking time) and what to do about it, including ways of making your lessons more student-centred – it’s an ELTchat summary from Sharon Noseley. Here are other tips on getting the TTT/STT (student talking time) balance right. Finally, this is what the students hear when you speak too much/unnecessarily in class.
Both of these will affect your ability to build rapport with students. Chris Ożóg offers more tips on how to increase your rapport in a 10-minute webinar.
Jonny Ingham‘s Back to Basics series includes a guide to getting instructions right. You might want to follow them up with instruction checking questions if there’s a potential for confusion, or one of these alternatives from Ben Naismith. Edward Evans has a 10-minute webinar about giving efficient instructions, including how to check them, as does Jo Gakonga: giving clear instructions (13 minutes). She also has one on setting up and running activities (12 minutes). Marc Helgesen has lots of tips for setting up activities effectively. Here is a 3-minute video of instructions for making a mini book by Jane-Maria Harding da Rosa – it’s designed for young learners, but the way she does it would demonstrates clear instructions that would work with adults too with only minor modifications.
It’s important to remember the students’ names as quickly as possible. Adam Simpson gives you 10 techniques you can use to do this, as well as suggesting a few different ways to arrange the furniture in the classroom. Celeste Lalonde has some creative ways of putting them into new pairs and groups (though don’t spend hours planning this!). ELT Concourse has a guide to classroom organisation, with lots of useful diagrams, and another on grouping. Pete at ELT Planning reflects on the relative merits of different ways of organising the classroom.
Laura Patsko offers some general tips for a clear and useful whiteboard in the final section of her Whiteboard Wizardry blogpost. Peter at ELT Planning has a comprehensive guide to using the whiteboard with some very clear illustrations, including for classroom management. Anthony Schmidt also has examples of whiteboard use – there’s no commentary, but it’s interesting to reflect on which layouts are likely to be more or less useful to the students.
Rachael Roberts explains how and why to monitor and provide feedback, and here are my tips on the same topic. Pass the CELTA shows how to monitor each kind of activity (reading, speaking etc) and some common problems trainees have. Karen McIntyre describes the many purposes of monitoring in a 10-minute webinar. Amanda Gamble offers many alternatives to the teacher eliciting the answers in open class at the feedback stages of lessons. ELT Concourse encourages you to consider how you’d give feedback in 6 different situations. Joe O’Hagen has a 10-minute webinar offering suggestions for providing feedback, particularly on speaking and writing activities, and Jo Gakonga has a 12-minute webinar.
Teaching receptive skills
ELT Concourse ask what is reading, then show you how to teach it.
Fergus Fadden has a webinar on teaching reading skills (7 minutes). You can also watch Fergus in action teaching reading to an elementary class (22 minutes). Jo Gakonga has a webinar on exploiting reading texts (35 minutes).
ELT Concourse ask what is listening, then show you how to teach it.
Fergus Fadden has a webinar on teaching listening skills (9 minutes).
Marek Kiczkowiak has 15 tips for planning a listening lesson. Number 13 is particularly important!
If you can’t find the CD, Martin Sketchley suggests a few solutions. This might help you with your anticipated problems in a listening lesson.
Teaching productive skills
Jo Gakonga has webinars on:
ELT Concourse looks at the differences between slips and errors, and how to handle errors in the classroom. They also ask what is speaking, then show you how to teach it. Simon Thomas offers tips on correcting students while speaking, and Zarina Subhan tells you why sometimes students don’t say much and what you can do about it, helping you to increase STT.
I have a step-by-step guide to setting up an information gap, a speaking activity in which each student only has part of what they need to complete the task and they need to speak to others to complete the information.
This post has ideas from five different teachers on how to maximise student talk time, the most useful of which is probably Dorothy Zemach (the first) demonstrating how to model the kind of conversation you expect your students to produce. Doing this makes them more likely to produce quality talk, not just short answers.
ELT Concourse ask what is writing, then show you how to teach it.
Catherine Morley has a step-by-step guide to planning a writing lesson.
Jo Gakonga has a webinar on giving feedback on writing. (34 minutes)
Jo Gakonga has a webinar on analysing language and anticipating problems (21 minutes) and Fergus Fadden has a 7-minute one on language analysis. Pete at ELT Planning shows an in-depth example of analysis of a grammar item and a vocabulary one, plus general tips on how to analyse language. Alexandre Makarios explains why language analysis is important, gives an example of a poor one with tutor comments and offers tips to help you with yours.
Jo Gakonga also has a webinar introducing you to PPP, TTT and TBL – three different ways of presenting language, whether grammar, vocabulary or functions (35 minutes). It will tell you what the abbreviations mean!
Jonny Ingham‘s Back to Basics series includes a guide to concept checking both grammar and vocabulary, as well as examples of clines. Marek Kiczkowiak offers seven ways of checking understanding without asking ‘Do you understand?’ and gives you 10 situations to test whether you can chose the most appropriate way to do this. ELT Concourse also looks at questioning in the classroom, and gives more ways to avoid questions like ‘OK?’ and ‘Is that clear?’ Concept Check Questions (CCQs) are the bane of many CELTees lives – here’s a fun introduction to what they are. Fergus Fadden has a webinar explaining how to create and use them (13 minutes).
Another common problem is how to elicit language from the students and Damian Williams has some answers. Pass the CELTA has a step-by-step guide to eliciting including lots of examples of what you can elicit and tips on what not to do. Jonny Ingham shows you to how to elicit vocabulary when pre-teaching in a reading/listening lesson.
Anthony Gaughan has an 8-minute audio podcast for CELTA trainees on what makes good controlled practice and how to make sure students really understand.
Jonny Ingham‘s Back to Basics series includes an introduction to timelines, including some beautiful examples which I’m very jealous of. Joanna Malefaki also has examples of timelines and CCQs. Marek Kiczkowiak offers tips for producing effective timelines. Gareth Rees shows some of the possible conventions of timelines (i.e. what the symbols mean). ELT Concourse has examples and asks you to guess what they show, then demonstrates how to build up a timeline with learners in the lesson. Anthony Gaughan demonstrates how to teach form without terminology.
Jo Gakonga has webinars on:
Do you feel “I need to teach vocab, but I don’t know where to begin!“? Adam Simpson can help you, particularly in sections 1 and 2 (3 and 4 are probably better left until after you’ve finished CELTA). Marek Kiczkowiak suggests ways to clarify the meaning of new vocabulary. ELT Concourse has a series of guides to teaching vocabulary.
Jo Gakonga has webinars on:
ELT Concourse have a step-by-step guide to understanding and teaching functions, complete with lots of examples. If you’re still not sure what a functions lesson looks like or is for, this 5-minute example from a real classroom based on students renting an apartment should give you a better idea. Languages International have a pdf document you can work through to find out what functions are and how to teach them. When you’re filling in your language analysis sheet, this non-exhaustive list of functions might help you identify what function the exponents (sentences/structures) you’re analysing have.
Adrian Underhill explains how the phonemic chart (which he put together) works in this one-hour introduction on YouTube, full of great techniques for introducing the sounds to your students. He also has a very useful blog breaking down the sounds and showing you how to find them in your mouth, and how to teach them to your students. For a shorter introduction to the same chart, try Jo Gakonga‘s webinar: introducing the phonemic chart (37 minutes). Rachel Daw recommends books to help you familiarise yourself with the phonetic alphabet (best used before the course). ELT Concourse has a series of activities to help you feel more comfortable with transcribing pronunciation.
Use learner dictionaries to get the phonetics for individual words in American English and British English. Rachel’s English has individual videos for each sound in American English. For British English, try this from the BBC.
Pronunciation Bites has a collection of links to online transcription tools, along with reviews for each. It also tells you how to download IPA (International Phonetic Alphabet) scripts onto your computer, and how to use them. Don’t forget to put the phonetics into Lucida Sans Unicode font to make sure they’ll print on any computer (I hope!)
ELTchat is a weekly hour-long Twitter conversation which happens every Wednesday. In February 2012 there was a discussion about the IPA, including reflection on its usefulness and suggestions for how to exploit it.
Julie Tice has tips on making drilling more fun and varied. Lee Shutler has some ideas too, and also talks about the benefits of drilling. ELT Concourse looks at the arguments for and against drilling, then provides examples of different types of drill. Marc Helgesen’s tips about pronunciation, drilling and task repetition are in the second half of this post about classroom management. Jo Gakonga has a webinar on teaching beginners, which includes tips on drilling (22 minutes).
Jo Gakonga has webinars on connected speech:
Jo Gakonga has webinars on:
Cuisenaire rods are a useful tool for a whole range of activities. John Hughes has a video showing how they can be used, and Ceri Jones and I wrote a blogpost with lots more ideas.
Mini whiteboards are another great resource. Phil Bird has some ideas for how to exploit them.
Observing and being observed
Rachel Daw summarised all of the things she learnt while observing her peers and receiving feedback on TP in the first two weeks of her CELTA course in CELTA Teaching Practice: some tips (an incredibly useful post!).
Martin Sketchley offers advice on preparing to be observed, much of which will serve you well in the real world too.
Nicky Salmon offers tips on how to reflect on your teaching during CELTA courses, including examples of language you can use. As she says, reflection is a skill which takes time to learn, but is one of the most important things you can do to develop professionally.
Teaching in different contexts
If you’re teaching young learners, try these links to start you off:
I have dedicated blogposts with links for business English teaching and doing the FCE (Cambridge First) exam (this one is for students, but should still be useful) – just one example of the many EFL exams out there. In any classroom you may have to test students, so this guide to testing from ELT Concourse will help you to think about the related issues. Teaching academic English is another possible avenue, and Adam Simpson has some tips to start you off. Jo Gakonga has a webinar on teaching beginners (22 minutes)
There are four assignments on the CELTA course. I’ve divided the links by assignment.
Focus on the learner
Jo Gakonga has a webinar introducing this assignment. (18 minutes) Remember that the rubric might be slightly different at your centre. Her tips are still useful though.
In the first part of the assignment you’re normally required to create a profile of the learner(s) you’re focussing on. These factors which affect learning from ELT Concourse may help you to do this.
You may also be asked to analyse the ‘learning style’ of the students. This article from ELT Concourse should provide some related food for thought.
Language-related tasks (language awareness)
See links in the Teaching language section of this post.
Skills-related tasks (authentic materials)
Jo Gakonga has a webinar introducing this assignment. (16 minutes) Remember that the rubric might be slightly different at your centre. Her tips are still useful though. She also has one on using authentic materials. (38 minutes) You can find other ways to exploit authentic materials in this summary of a one-hour Twitter chat (ELTchat) on the subject. Pete gives an example of his assignment on ELTplanning.
Lessons from the classroom
Jo Gakonga has a webinar introducing this assignment. (12 minutes) Remember that the rubric might be slightly different at your centre. Her tips are still useful though.
The links from the After the course section of this page will also help you here.
Surviving the course
Here’s a list of do’s and don’ts to help you survive the CELTA from Alexandra Koukoumialou and 5 secrets to success on your CELTA course from Tanya Hacker, and another 5 tips from somebody who completed the course at IH Bangkok (I can’t find their name unfortunately!)
The main problem most people have with the CELTA is the workload. It’s not unusual for some trainees to stay up for most of the night and forget to sleep, and there are always some people who don’t hand in lesson planning documents because they ran out of time. In a 10-minute webinar, Lisa Phillips offers some tips for time management for teachers in general, but many of them apply to the CELTA course too. Remember to ask for help if you need it – you’re not bothering people, and you might find they’re in a similar situation. As for your trainers, that support is what you’re paying for!
I know I included it in the lesson planning section, but these suggestions for approaching planning are designed to make your life easier, so I think they’re worth repeating.
Don’t forget to take some time for yourself during the course. You’ll benefit from it more than you will by just pushing on through, and no matter how important the CELTA is, your health and well-being should take priority. Get enough sleep, look after yourself and take regular breaks. If you need inspiration this might help:
Here are a few of videos I send out to encourage my trainees to take a brief break – I won’t tell you what they are so it’s a lucky dip! One, Two, Three – each one is 3-4 minutes, clean, and should make you laugh!
And just in case you think you’re entering a serious profession involving a lot of work, take a look at EnglishDroid – he’ll burst your bubble quickly (this is a site to return to as you learn more about the world you’re entering!)
After the course
You’ve survived! Well done! Now what?
Once you’ve finished your CELTA, you’ve got all this to look forward to. But first, you need a job. Here are a few places you can look (but there are many, many more!):
To help you Jonny Ingham tells you how to write a TEFL CV and Karenne Sylvester explains how to avoid overseas EFL teaching job scams. Gordon Scruton gives you questions for a potential employer, plus all important social questions about life outside the school. Rachel Daw talks about her experiences getting work as a newly-qualified freelance teacher and shares examples of questions she’s been asked in job interviews, as well as comparing the relative merits of working for a language school and being a freelancer. Adam Simpson gives you general advice about what to say and do in job interviews. Once you’ve got the job, Elly Setterfield has a very useful series of posts specifically designed for new teachers, answers questions such as’What should I pack?’, ‘What if I hate it?’, and with Teaching Kids and Teaching Teens 101s.
Isabela Villas Boas offers tips for a great beginning in a new teaching job. Richard Whiteside has 3 things to help new teachers. Lewis Waitt tells you about how to survive your first year as a teacher. Michael Walker has 5 tips for new teachers. Rebecca Cope describes what it’s really like, from the perspective of being six months into her own first year as a teacher. Elly Setterfield offers tips for planning on a daily basis, as it’ll be hard to keep up the amount of detail you had to produce during the course.
To continue the reflective cycle you started on CELTA, you could keep a reflective journal, as recommended by Dale Coulter. Another option is to write your own blog, which I’ve found really useful. However you choose to do it, Jason Renshaw explains why reflection should be a vital part of any teacher’s development (and offers another suggestion for how to keep a reflective journal).
I’ve got a starter list of blogs which are good to follow post-CELTA. One of the things I enjoy about blogs is periodic challenges which bloggers start and anyone can join in with. The #youngerteacherself posts kick-started by Joanna Malefaki are a great source of advice for beginner teachers, as experienced teachers look back and offer advice to their younger selves. A couple of years before this challenge Chris Wilson wrote 10 things he wished he’d known before he started CELTA. ELTchat also had a chat called I wish I had known that when I started teaching! If you’re thrown into a classroom with a horde of children or teens, you should find these posts by Elly Setterfield very useful: Teaching Kids 101 / Teaching Teens 101.
Adam Simpson has a series of blogposts aimed at helping you develop post-CELTA:
There are lots of other online resources for professional development. Jo Gakonga has a webinars on continuing professional development on the web (37 minutes) and using Twitter for professional development (25 minutes). I’ve put together various guides to help you get into online professional development, including Twitter, webinars and facebook for professional development and a webinar called 10 blogs in 10 minutes. All of the names linked to in this blogpost will take you to Twitter pages if you’d like a few people to follow to start you off, as well as me of course!🙂
The best resource on Twitter is ELTchat, a weekly one-hour chat on topics chosen by participants. Summaries of chats going back to 2010 can be found in the Summaries index on the website and cover pretty much every topic you could possibly imagine related to ELT teaching – if it’s not there, you can suggest it for a future chat.
International House offer a range of paid courses to extend your knowledge in a variety of areas, including language awareness (IH LAC), business English teaching (IH BET), teaching young learners and teens (IHCYLT) and teaching online (IH COLT). They are offered online, face-to-face at some schools, and in the case of the IHCYLT, blended. You get a discount if you work for IH, and some schools will pay for your course completely if you work for them for a particular period of time. Adi Rajan has also put together a list of post-CELTA qualifications; although aimed at teachers in India, it’s relevant worldwide.
You can join a teaching association to get support. Ask around and you might find one in the city or country you’re working in, like ELTABB in Berlin. You could also join IATEFL (UK-based) or TESOL (US-based), international organisations which also have lists on their sites of country-based affiliates, like BELTA in Belgium or TESOL France (both of these websites also have lots of other resources). Here are some of the benefits of joining a teaching association.
Cambridge English Teacher and the International Teacher Development Institute are online communities with forums, webinars and courses you can follow. CET is paid, but you can get benefits like cheaper subscriptions to journals with your membership. iTDi contains lots of free content, and a couple of more extended paid courses.
Conferences are a great source of ideas. Both IATEFL and TESOL hold multi-day conferences each year, and although the IATEFL conference is the highlight of my year (!), they can be quite expensive. IATEFL streams some sessions from the conference, and these are available to watch after the event (for example Harrogate 2014). One- or two-day local conferences can provide lots of inspiration. There are also online conferences and webinars provided for free. David Harbinson has a long list of sources for webinars to start you off.
There are various journals and magazines dedicated to ELT, full of articles from around the world with lots of great ideas and issues to think about. The IH Journal is available free online. Most teaching associations have their own newsletter or journal. Other magazines include English Teaching Professional and Modern English Teacher, both of which are subscription only – you can choose whether to get them online or as a hard copy.
If this list isn’t enough for you:
For CELTA trainers
(Just so you don’t feel left out!)
I wrote a weekly diary of a CELTA course I tutored on in Chiang Mai, with reflections on the day-to-day experience of being a tutor: week one, week two, week three, week four. I’ve also talked about integrating technology into CELTA.
Jo Gakonga has a webinar on ‘flipping’ CELTA input sessions. (22 minutes)
Matt Noble regularly posts reflections on being a trainer on his Newbie CELTA Trainer blog, as does Ricardo Barros on his. Anthony Gaughan talks about a completely different way of doing CELTA on his Teacher Training Unplugged blog.
John Hughes offers various ways of approaching lesson feedback.
Ruth Lavina shares 10 things she learnt on her CELTA, covering a whole range of categories above. I particularly like number 7, because trainees often forget it!
As I said at the start, please let me know if any of the links are broken so I can update them, and feel free to add suggestions to the comments. I hope these links are useful!
