In regards to PowerPoint, let me say that I am a very huge supporter of using this type of teaching style in the classroom. Whether or not it is appropriate to use all the time in a language teaching environment is another story. I personally use PowerPoint in the classroom almost every day, reason being that my students have always responded positively to this type of class. That’s not to say that I use it for the whole class period, though. Throughout the past two years or so I have tried varying my formats and including grammar exercises in my presentations because it gives students a chance to interact more with me and themselves and also keeps the classroom alive, whereas if I present a grammar topic all on PowerPoint and all they do is look up at the screen and write down answers, then everyone falls asleep on me, and that’s not too good for learning.
PowerPoint is also very useful in vocabulary lessons in my classrooms, because it lets the students practice their pronunciation when they identify an object on the screen, and I can also improvise conversation with different students when they see the different pictures based on the lesson that day. I also send my students the power points that we use at the end of the week, with additional exercises they can do at home to practice what we have gone over. Some students are actually dedicated enough to come in to office hours, but usually they all prefer to check them in the classroom as a whole.
PowerPoint has its setbacks, unfortunately. One of them is that the presentation tends to get boring if I don’t include exercises between them. My voice going on and on and the monotonous screen can be a bad combination that just leads to everyone falling asleep, which is why I decided to start doing exercises in the presentation along with on the board. Also, I have included different sounds and effects which students always seem to like. Another drawback I have found is that if the students know I’m going to send them the presentations, then some of them don’t pay attention in class and decide to look at all of it on their own, which is why I am now sending them all at the end, when we have covered everything.
In short, I have been a fan of using PowerPoint since I started teaching. It gives students a chance to look at and hear something else besides me, and vice versa. It also gives me the freedom to change my lesson around if need be, and go back and forth and compare slides whenever there is confusion, and initiates participation among themselves when it comes to group activities.
