The primary job of a lecturer is design of the lecture, select the material and structure it. That requires insight, experience and understanding of the target audience. The second most important thing is teaching the material and that requires a lot more than just standing there and reading the slides. In fact, just reading the slides is a complete fail. What you need to di is talk about what is ion the slides, signal what is important, how this relates to the rest of the world, what is the future perspective and, most important, do a bit of storytelling with real-world examples not on the slides, etc. The students must have the impression you know your stuff, and that you, as the lecturer, respect their time and provide something of value. That is what keeps them engaged and is critical for the learning effect. Things must be _interesting_ for them.
Hence this "course" is a complete fail and waste of time and essentially a scam. The students would have been much better served by being told to buy a specific book and to work through it.
