It is so important to find out more about courses before you study them and a teaching demo can be part of this. It is a really good idea to find out more about what to expect and can demonstrate specific things about how the course is taught. You should be able to find out the things listed below by watching a teaching demonstration.
Understand teaching style
You will be able to get a better understanding of the teaching style. This may not sound important, but if you have ever had a poor teacher you will know the importance of it. Some teachers are not good at explaining things or they just read notes and do not answer questions. This may be fine for some learners, but others may prefer a more flexible style where they can ask questions or have things covered in more depth. Also some analytics courses use a mixture of notes and video to teach and this could suit you. However, you may prefer notes based learning or video based learning and so you need to know how much there is of each style to decide whether it is the right course for you.
Learn more about training company
It is also wise to find out more about the training company themselves. The demo may give you that information and you will be able to decide whether they sound like the right company for you. You may like a certain approach, experience or whatever and looking at their demo you should be able to get a feel for this.
Understand what the course entails
It is so important to understand exactly what the course involves. This goes beyond the learning style but includes how it is assessed, how much teaching there is, what sort of tutor and student contact you get etc. You want to know what sort of notes you will be given and how much help you will get with any questions you may have as well. All of these things could make the difference between you passing and failing a course.
Find out more about students
It can be a good idea to find out about what sort of students use the course. This will help you to get an idea of who it is aimed at. It will also help you to know who you will be working alongside which could be useful if you get a chance to communicate with them while doing the course.
Find out success rates
It is a really good idea to find out how well students on the course do when they have finished. Find out what exam results they get as a result of their learning as well as how well they have managed to apply what they learned to their jobs. This may not be that easy to find out from a demo or website but a good one should have some information about it. If you want more than just ask the company running the course.
