And my head can be there in a box down in the corner being amazed at it all. would also be ideal for capture with ScreenFlow. Then, ideally, engage in a live Google Hangout with the site's excavator and one or two other scientists who want to complain about the excavator's findings for a steal cage death match showdown. So, you show a web page with a recent news report on some site, use Google Earth to fly from the site of the campus you are on to the location of the site, zoom in, discuss terrain and geographical context, then using the file viewer show a handful of photographs of the site, then open a spreadsheet page with some data, pull up a few graphs, and finally display a PDF file of a published report on that site for a detailed discussion. Incorporating a window with Google Earth, especially including a pre-programmed fly-over is a nice touch as well. Then, as part of the lecture presentation one opens web browser pages, graphics using a file viewer, sections of spread sheets, etc. Using this method, instead of showing a presentation on screen in a lecture context, you show your computer's desktop on which there are various files, perhaps even folders of files. ![]() I've done this sort of thing as a lecture tool to some effect. One can also get entirely out of the "presentation" (read "PowerPoint") mode as well, by simply recording the display of graphics via a file viewer, or for that matter, PDF's. There is even a facility to have a text-to-speech insertion, so I can have a computerized voice read off part of the presentation, though I'm not entirely sure yet why I would do that. Aside from the presentation itself, one can add text box overlays or other graphic elements. ![]() Your talking head can be in a little box in the corner, the box can be moved, or it can be made invisible. Your head, talking, and your voice are then joined with the presentation you are running through. Presentation, then "film" oneself giving the presentation. So, for example, one can make a Libra Office Impress or Keynote It allows one to specify a window or screen to capture, while at the same time (optionally) to record video and audio off of the hardware built into the computer. Pursuant to this, I've been looking at tools to help make this work, and on the advice of Peter Sinclair, famous for his most excellent climate science related videos, I've obtained a demo copy of ScreenFlow Also, I don't intend to create a fully reversed classroom I'll use this technique for parts of the course, distributed across the semester. The on line "lecture" would be broken into smaller-than-lecture bits, and involve more interactive tools, and the in-class activities would involve more group activities and tutorials. In reality it is a bit more complex than this, because a "lecture" converted to an on line resource may, and probably should, be very different than an in-class lecture, and the activities that are done in the classroom would not consist of students sitting by themselves reading or doing some sort of work. The simplest version of this idea is that classroom lectures are converted to an on line resource that the students access on their own time, and what would have been study or homework time is done in the classroom. This is an idea that is being increasingly applied in High School settings. Next Fall, I will probably try something new in teaching an intro Biological Anthropology course: The Reverse Classroom. ![]()
