Effective Use of Technology In the Classroom?

postermmxvicom writes "I remember in college I had one professor who, in addition to being a great teacher, really took advantage of the technology in the classroom to illustrate the concepts for Calculus and Linear Algebra. Well, now I am the teacher. I teach Algebra, AP Calculus, and Physics in high school. This year I have gotten a tablet and a wireless projector. Now I can write on my tablet instead of the board, as well as use other applications. I want to utilize this tech effectively for teaching. Would you please share how you have seen technology effectively used for Math and Physics — either specific software or how that software was used (specific or general)?"

Ways to use the technology

[confused one]

One way the tablet is better than a blackboard is that you can save a written copy of your lecture, and make copies available to the students. That way they can spend their time paying attention to the lecture, instead of rushing to copy everything down. This can make the class more interactive.

The PC can be used, in general, to demo the physics and calculus principles through animation. It can be a useful teaching tool, just don't let it replace the hands on activities usually done in the lab portions of the course. Sometimes doing is better than seeing.

Animations and 3D

[Zaph0dB]

In my university days, I understood a lot of calculus by visualizing an animated sequence (mean value theorem, limits, derivatives...). Animation is a great tool for these things. Same goes for numerical analysis.
Also (from the same days), linear algebra can be (often / sometimes) simplified to a 2d / 3d projection which can be displayed easily by a computer. Forget that you CAN'T draw in 3D or can't animate in 2D on the board - the computer can.
And of course - physics, chemistry, geography, history - omg, history would be so cool to learn with a projector, if done correctly (not just clips - diagrams, arrows on the world map describing population movements, pressures, wars) - all of the "real world" sciences are much more fun when working in the real world. Even political science (if your school offers it) can enjoy the benefits of a projector, even if only as a video machine (watching Marting Luther King Jr. making his speech for example).
However - I don't think that a projector is a "magic wand". It conforms to the equation "invest more time, reap more results". If you invest the proper amount of time preparing good material (and not only video clips), your students would enjoy it immensely.
Just my 2 bits.
