One other advantage of the transparencies is that they can easily be converted to notes for web (or even handouts) by running through a scanner (or copier). If you have a canned talk, it is a very different energy. If you want to keep the same feel as blackboard talk, I recommend to write them as you do the discussion. (Number as you go, to make this easier, on the fly.) You won't have the multiple boards, but you can go back to earlier pages if needed. You might consider to just use an overhead projector, with grease pencil and acetate. The one situation we haven't found a solution to yet is: if you have slides that reveal in stages, and write on an earlier part of the slide, the writing 'disappears' when you bring up more of the slide. On the flip-side, you can save the file and upload it to your VLE, so it's not as bad if students don't have time to copy everything in the lecture. However, I've not come across anything that allows multiple boards to show at once (unless you spend a LOT more on tech). These can generally cope with the hand/stylus issue, but can allow finger-writing as a back-up option. I'm going to try using OpenBoard, which is free, but still somewhat buggy (most noticably the button sizes are off on my screen). The advantage of Acrobat is you can write onto pre-prepared slides. If you just want to write onto a plain page, OneNote will probably serve the purpose, and has the best writing experience. My colleagues have been doing this using a Surface and Acrobat. This also does not allow me to display multiple "boards" at once, but it is very quick to scroll back through earlier pages, or select an earlier page from a list of thumbnails. The main disadvantage of this method is the high cost of the Apple products. a computer algebra system graphing software etc.) (This app is very flexible with different pens / highlighters / selection tools / etc, and the developers are regularly updating it with new functions) The purpose of also doing the screen capture is to (i) record the lessons, and (ii) allow me to quickly switch from the screen capture application to project other useful applications (ie. I use the Notability app on iPad to write notes (using the Apple pencil), and this is projected for students to see. I then display my notebook via a projector. I connect my iPad to my notebook, and screen capture my iPad onto my notebook. I am teaching at the high school level, not university, but this has been my standard set up for a couple of years now: A document camera is similar if you get the right one. The videos linked below I use a camcorder fastened to a wood frame I built about 50cm above where I'm writing. Incidentally, this is more or less how I've made some of my videos for advanced students' independent study. Time pressure teaching, markers on paper ftw. Maybe after I spend a couple hundred hours it'll start feeling natural. It does help, but it is still rather ugly at my current skill level. I own a Bamboo tablet which attempts to recreate some of the texture we take for granted with paper/pen/pencil writing. Personally, I think the electronic pens leave a lot to be desired and I've spent a few hours trying to create legible content for grading purposes on pdfs. I like this as a solution since it is relatively low-tech and is more close to your usual style. I think you can route a document camera into an hdmi or vga connection. This gives you the advantage of drawing things before class without much planning and/or going back to previous "slides" by simply retrieving the relevant paper. Use a document camera with lots of paper and markers. Does anyone have any experience doing this?
