Student motivation
Motivating students can be hard, especially if they aren’t interested in the subject you are teaching. Looking back at my own experiences as I student, many of the teachers that I found to be the most motivating in college paid attention to the students’ personal interests and tried to incorporate those interests into class.
Get your students excited about learning English by asking them about their favorite movie, book, video game, sport, hobby, celebrity, musician, etc. Some might feel that it’s a little “unproductive” to spend class time talking about entertainment, but if gets your students to enjoy speaking/listening/writing/reading in English, not only will they have more fun, but perhaps they will be more likely to pursue those interests in English outside of class on their own in the future.
For example, suppose your students are all big music fans. Try to figure out what kind of music the majority of your class likes and find a English couple of artists or songs that might interest your students and play them in class. Showing them a popular English-speaking musician is also a good route. Just make sure that what you show them is classroom/age/level appropriate! Also, if you can find a song that features some of the vocabulary, grammar, or culture points that you are currently studying, this can help remind students that what they are learning can be useful.
Continuing with the music theme, have your students read an article about a popular English song or musician. Discuss the article together, and have your students go home and write you a short article about their favorite singer/musician based on the format of the class reading. If motivation is your main goal, give them as much creative freedom as you can without sacrificing structure too much, so they can really explore what interests them.
Depending on your students, you can alter this activity to be about literature, film, sports, or whatever hobbies your class is into. No matter how you alter these activity suggestions, just remember that the main goal is to show your students that learning English is worth their time and can even be fun by exposing them to English content that truly interests them.
