Recently I started a teaching job, and I've been using the Beamer package in LaTeX (through ShareLaTeX) to create colourful and illustrated presentations for use in my lessons. This is an example of one I made.
Whilst I would love to be able to do this for every lesson I teach, I find it does take a very long time to make, considering how I need to be careful when using the "only" and "uncover" commands, which I've used to uncover specific steps of mathematical working. I'm really happy with the results, but I've only been able to put presentations like this together for one-off lessons, rather than a regular habit (as I will be having to do 10 lessons a week as of tomorrow at my college!) I really don't want to use PowerPoint as editing equations in that can be very fiddly.
Does anyone know of a software package similar to LyX (which I normally use for creating LaTeX documents), that allows Beamer presentations to be created in this way?
