YouTube - PLC Programming

I used YouTube to watch a tutorial on PLC programming. I found it very helpful because it is easier to listen to somebody explain how something works rather than simply reading a description.

Advantages:

- Easy to use and find required information.

- Lots of different videos that use different sources of information.

- Easier and often quicker to listen to somebody talk than read a book about the subject.

- Ratings and reviews provide a good idea of how good or bad the video is.

Disadvantages

- Not all videos provide accurate information.

- Can be hard to quickly find certain information without watching the full video.

- Need to be in a quiet environment in order to listen to videos.

- Requires internet connection

- 'Suggested videos' tab can be a distraction when watching video.

Khan Academy

PROS of Khan Academy

It is free and accessible. It costs absolutely nothing to watch videos and work on problems. It is available anywhere with internet.

There are a wide variety of subjects available. There are videos about maths, biology, chemistry, and physics.

You can learn and work at your own pace. You can fast forward, rewind, repeat videos, stop and work out a problem on your own, all without having to consider other students’ or the teacher’s pace.

It provides an incredible amount of math problems for a variety of grade levels (from very basic elementary concepts through calculus). One of the best ways to learn is through repetition.

CONS of Khan Academy

It is less interactive than having a face-to-face teacher or tutor.

You are only exposed to one teaching style.

You lose the collaborative aspect of education.

It lessens spontaneous creativity.
