Although the pronunciation included in the videos might be slightly different from the ones we are used to, I have two favorite British websites that are completely useful. They have podcasts, programs, grammar exercises, resources, and articles about English teaching.
http://www.bbc.co.uk/learningenglish/.
https://www.youtube.com/user/bbclearningenglish
It also has a YouTube channel, which is mainly focused on learning, but they can help you get ideas to teach with their outstandingly creative ideas, such as talk shows explaining grammar and a pronunciation workshop.
https://www.britishcouncil.org/
Here the main focus is on podcasts. It has many videos and lectures in the downloadable app, too. They are crucial for teaching to study for standardized tests as TOEFL, TOEIC and others.
In order to avoid the preference over British sites, I also suggest you revise these two YouTube channels to learn American pronunciation.
https://www.youtube.com/channel/UC-MSYk9R94F3TMuKAnQ7dDg
In their app-based videos, all the phonemes of American English are taught in context, with their corresponding examples and phonemic transcriptions.

Motivation is an important factor for people to continue learning since a person without motivation does not allow him/herself to learn more. That is why, I think this video can help people who want to continue acquiring knowledge.

I also think this material could help a teacher who wants to enrich his/her knowledge, for there are some programs that allow teachers to learn online and help them to improve their skills.

This Guatemalan English teacher shares what she does in her experiences. Ranging from her decision to become a teacher up to warm-up activities and videos of whole classes, Lucie enthusiastically includes all what an EFL teacher wants to know. The best part is that her videos are in Spanish, as she teaches English for Spanish speakers.
https://worksheets.theteacherscorner.net
This is a very useful website in which we can create worksheets for our practices; for example, we can create crosswords.
https://www.englishgrammar.org
This site lists the grammar rules of the English alphabetically, and they are easily accessible. Not only that, they provide PDF files of lessons on these rules that you can use with your students.

For me, this site is the ultimate resource to understand phonology of English. Rachel explains the pronunciation of actual words in daily speech. She deconstructs conversations into the sounds and explains phonological variations, such as the flat T, assimilation, vowel reductions, etc. Rachel has a series of videos of many often-mispronounced words for free.

The link talks by itself. In there, you will find many useful and practical tips that will help any teacher to teach a foreign language. What caught my attention in that article is that it is focused in student-centered instruction. These tips help teachers bring context into the classroom and motivate students.

This TED Talk is very interesting since it may help teachers introduce them into the students’ world. What the behaviors mean, and what are the messages that students usually send, consciously or unconsciously.

I recommend this article because I think that we as teachers EFL need to cultivate the interest in learning languages. This article provides some good suggestions to motivate students.
