Lesson 14: Maximizing the use of the OPH and the Chalkboard




In this topic maximizing the use of overhead projector and chalkboard it is the use for the new technology for this generation, as what we know during our time when we are in elementary and high school we are using the blackboard in every classroom for our materials.But because of our new technology some of the school are using television, a computer in presenting their lessons. It help so much to our new learner by using computers, TV's and other technology that can be use in the classroom. And this Overhead Projector seems more available in schools and it has a lot of advantages. So now, we already know and learned the technology we should maximize using the chalkboard
We've known the chalkboard since nursery and even in offices, chalkboards are used. It is a very helpful tool especially in schools that do not have computers, televisions and the like. There are tips on using the chalkboard to make it and effective learning tool.
- writing clearly and legibly can allow students sitting in the last rows to read what you're writing.
- be prepared on what to write on the board
- use colored chalk to highlight key points
- write on the board while still facing the class. You don't have to turn your back on your students while writing on the board.
- while students are copying their notes from the board, try to walk around and see your board work from all corners of the classroom to see its visibility
- check for glares from fluorescent bulbs and windows.
- use the chalkboard to its full potential.

There's a trivia on why chalkboards are usually called blackboard. Way back then, chalkboards were painted black and white chalk was used. Then people discovered that green is much more pleasing to the eyes and so they started painting it green. But the term blackboard was already hooked up with the tool.

Another good tool to use in place of computers and televisions is the overhead projector (OHP).
- it's simple to operate
- the instructor can face the class while operating the OHP
- creating the materials for the OHP is easy and fun.
- graphs, charts, diagrams and other visual symbols can be shown using the OHP
- you can overlay transparencies to show the after-effects of a certain process.

There's a good side to the OHP. When you use a computer, you usually store your presentation in a flash drive. The downside to this is when it has a virus or your flash drive is not detected by the computer. With the overhead projector, you don't have to worry about these things. Just turn it on, put your transparencies on and viola! you get a presentation
