One of my teacher liked this tweet

I'm wondering if it is a hidden message for some of our teachers 🤔

Just wondering, is it teaching if the teacher made a good and informative powerpoint? Should (s)he just give the PowerPoint to the students without going through it. Or should (s)he speak about he topic without placing the information on the slides?

This is a genuine question as I’m a programming teacher, students are not always paying attention during long lectures, while the books often contain to much information. Summarise it on the sheets is a tactic I often use. So why is it not teaching?

@valvy handouts are great, but you still need to explain everything in more detail.
If you only say what's on the slides, either you have too little content or your slides have too much text.
My rule is to never have more text on a slide than fits on a sticky note and to talk about each slide longer than it takes a dyslexic person to copy it.

@valvy I think a good lecture is when the teacher teach the course the same he will tell a story. It is far more attractive to learn something if it is not just a list of facts and concepts but materials that can be linked to our world and our knowledge. The idea is to give the lecture in such way that the student have a clear vision of the subjects. If you think they can explain with their own words what you just said then your job is done.

Besides, if the students struggle to keep their attention high for long lecture maybe try making a 5' break every 25-30' ?

Teaching is hard. So engage your students in what your doing by giving examples or explaining with basics facts or making comparisons with the real world. But do not just read the PowerPoint.

There are some teachers, that do what is on the picture, but they're so unenthusiastic and numb about what they teach, that I genuinely am bored... For example there is a teacher in my uni, who teaches this way - so I'm present on lectures to get the points for it (though browsing through memes / devRant), but when it comes to learning, I usually do it @ home by researching the subject on the internet and by trial-and-error...

@valvy what you are taking about is a teacher making additional course material because the original material is insufficient. The teacher here is not a teacher at all but an author.

PowerPoints, keynotes and other presentation helpers; are just that: presentation *helpers*. They should support what the teacher is trying to convey however it's the teachers job to make sure the students get it and get the correct meaning. This means the teacher has to pick up on students misconceptions, answer questions, lay out problems and examples and guide students to find answers/solutions to the problems with the proposed method and/or guard them for pitfalls and situations the method does not apply.

well... its true that you can and some teacher DO read off of the powerpoint slides. Its mostly because they teach multiple subjects and they do it every year... the same thing again. It gets tedious so the longer a teacher has had the job the higher the probabilityo f them reading off the slides.
I sometimes do it on some subjects im not an expert in but i share facts, stories and alot more information thats on the slide - alas is the student's own job to write down what the think is necessary as the only thing i give them after the lecture are the slides.
PS. Ever heard a professor or teacher saying "you cant pass this lecture with slides alone"? Thats exactly what they mean.

thanks
