Online teaching is all the rage now. This has led teachers and institutions to try and determine how to support students in the online context. One solution that many individuals and institutions are adopting is the use of live-streaming their classes. In this post, we will look at the pros and cons of live-streaming classes.
One advantage of live-streaming your teaching is the authenticity of doing this. Here you are live trying to instruct and connect with your students. This is hard to do in a prerecorded video, which should generally be perfect because there is time to fix problems. With live-streaming it is similar to the classroom in which all the warts and flaws of the teaching experience are there for everyone to see.
Another advantage of live-streaming instruction is the chance to address and communicate with students in real-time. This allows you to address questions while they are fresh in students’ minds and provides an opportunity to get to know one another. Again, this personal touch is not possible when making prerecorded videos.
Technical issues are probably the biggest problem with live streaming. Technology is impressive but often unpredictable. The microphone you’ve been using for weeks all of a sudden does not work. The internet connection is down or slow. Or maybe the students cannot see or hear or even cannot log in if required. All these things and more can happen when live streaming. In addition, these are all problems that need to be solved in a matter of minutes before students get distracted or give up with learning at that particular moment. If you do not have a strong technical background, it can be impractical to wait for IT to come to the rescue as you struggle to figure out what is going wrong.
To do quality live streaming incurs a moderate to high cost. You will need a microphone, streaming software, camera, and more to do this well. If you only want to sit in front of your computer, this will lower cost and quality. However, if you’re going to move around the room while teaching, you will need cameras that can follow you and a microphone to pick up what you are saying.
If moving through the classroom is a goal, you will need a cameraman to man the camera. In addition, if you want to interact with the students, you will need someone keeping track of any chat messages coming in through your platform or whatever messaging system you are using. If you are only sitting at your computer and live-streaming, it isn’t easy to keep track of the messaging and chats while teaching at the same time. Even a system that notifies you of questions is hard to notice because you are focused on your content. Of course, you can just let students jump in when they have a question, but this may not be practical for large classes.
The point is that quality live-stream comes with a cost. Sitting in front of your computer is much more cost-friendly than moving about in a studio or classroom. However, if the live-stream is going to be good, there will be some financial investment in equipment and software
Engagement can be challenging with live-streaming. The temptation is to lecture for the time that everyone is together. Teachers do this despite knowing that lectures are horrendously dull. If the lecture is prerecorded, students can skip around or play it back at double speed, which is beneficial for the faster students.
The engagement issue means that the teaching has to be good. This means having clear lessons, high expectations, and a strong knowledge of the subject. If you are sitting in front of your computer, it means you need to know when to show the content and when to move the camera to show your face. Cycling back and forth like this helps keep students awake rather than only showing the content or your face. Visualizing ideas by making pictures also helps. By drawing ideas using some software, it helps to keep students engaged.
The final problem with live streaming is something that isn’t the teacher’s fault, which is time zones. If students are spread out all of the country or world, this means there is no convenient time to live stream. I have heard of cases of students having to watch classes at 1 am because of live-streaming. This was hardly convenient for them.
This implies that live streaming may be limited to specific geographic regions near your institution. Of course, if you allow students to watch the video later, this will solve this problem. However, the option of watching the video latter means many will skip the live stream for the convenience of watching it later. Sadly, for many students, watching the video later means never watching it at all.
Live-streaming is for pros. If you are new to this, you need a lot of help, or you need to develop your technical skills to handle emergencies. You also need to make sure that you can teach in an engaging way, so people do not start surfing the net while trying to teach. This is an excellent tool for a particular type of teacher, and anybody can live stream and do a lousy job. For most of us, we need the flexibility of prerecording to iron out whatever problems we face when trying to transition to online teaching.
