Flipped learning
Why not try something different in class? This is a really cool way of blending human interaction and technology as part of your teaching. So, students can do more theory-based work at home, understand the topic and then, during class, do more interactive work, put into practice what they learned, and ask any questions they have to the teacher. I think this can work wonders to make lessons fun and interesting for the students, provided they have access to the Internet and they actually work at home, which is not always going to be the case, especially with teenagers.
For this task I've actually used two tools that I had never used before:
The first one is Edpuzzle, which uses videos in which you can insert questions. I found this tool really easy to use, incredibly intuitive, and you can just pick any video from YouTube, which is great!
I have tried focus this activity on the comprehension of the video. So, the questions you'll find there are related to the topic of the video, which is a very simple history of the English language
(you can take the girl out of linguistics, but you can't take linguistics out of the girl...)
Then, I created a quiz with Quizizz to test the passive voice using sentences that have to do with the topic of the previous video (the evolution of the English language). This tool works in a similar way to Kahoot when designing the test. It's pretty easy to use, though it did take me a bit to find how to share it here (link to share and complete the quiz, not to share and edit). Also, the free version only allows you to share the quizz for a period of two weeks, so if you want to have it up in a website like I have it here, it takes extra work to create the link again and again.
