Materials List:
|
The Organizer
The following is a list of equipment and materials that the organizer must provide:
|
| • | High-intensity overhead projector with spare bulbs. |
| • | Overhead pens, supply of blank transparency sheets, dry-erase markers for white board if that type of board is used in the classroom, or chalk and erasers for a chalkboard. |
| • | Name tags for participants |
| • | An LCD projector and screen for use with a laptop computer, TI Presenter and/or TI Smartview. |
| • | The instructor may need the organizer to request that participants bring copies of their textbooks so they can plan where technology can best be incorporated into their lesson plans. |
