How to Use LCD Projectors in Education
In the past, a teacher who wanted to display information for a classroom full of students had only a few options at his disposal: writing everything out on the chalkboard manually or projecting it onto a screen using a transparency projector. Today, the liquid crystal display (LCD) technology becoming common in homes has also made its way into the classroom. If you're an educator who teaches in a school equipped with LCD screens, you can incorporate this technology into your lessons in several ways.
Present class notes and materials using the LCD projector, just as you would have using an older device, such as a transparency projector. Connect the LCD projector to your laptop or desktop computer and open up the program that contains the presentation you'd like to give.
Use the LCD projector to show picture slide shows. Hook the projector up to your computer and play a slide show of images from your Pictures folder while you narrate the images in the context of the class.
Play video clips and even full-length movies. In almost all cases, your projector screen will be significantly larger than any TV you can bring into the classroom --- and probably clearer. Play any videos you have on your computer for your students or a pertinent DVD movie that relates to the topic of the class.
