Hands-on learning has become a common phrase in science education. Like many other highly used terms and phrases, there are various interpretations of what is meant by "hands-on learning." Rather than attempt to offer a definitive operational definition, we present in this section a variety of viewpoints on what is meant by hands-on learning in science. Then we address the issues of whether hands-on learning is a new phenomenon and whether hands-on approaches will continue to have a continual impact on science teaching and learning in schools.

The importance of student investigation of basic scientific principles cannot be overstated. Hands-on learning is the only way students can directly observe and understand science. As students develop effective techniques for observing and testing everything around them, they learn the what, how, when, and why, of things with which they interact. These experiences are necessary if the youngsters of today are to remain "turned-on" to science and become scientifically literate. Benchmarking of Physics Laboratory
