They might perform a demonstration that at first glance looks like magic and then invite their students to play science games to build on what they are learning. Through videos to CD-ROMs and the Internet, you will travel with y our students to rainforests and ocean floors, inside the human body, and under the lens of a microscope. They can use computers to help students carry out experiments that cannot be done in the classroom because of lack of time, space, or equipment. Or teachers can hook their student into computer networks to exchange information with other students around the world. Along with the many joys, however, science teachers also face problems.
Many teachers spend much of their own money to purchase materials for the classroom.
Other teachers feel constrained in having to cover too much material in too little time, and some face overcrowded classrooms and laboratories. Along with overcrowded classrooms, there is the dramatic, increasing change in the student population. Classrooms of today also hold another great challenge for teachers- technology. Teachers need to be prepared to use the Internet as a teaching and research tool, and to teach their students how to use it. Teachers also need to be familiar with and learn a variety of software programs that enhance instruction.
