Example text

Inquiry Teaching During the First Half of the Twentieth Century During the latter half of the nineteenth century the goals of science education were expressed mainly in terms of individual personal development. These goals included having a familiarity with the facts and principles of science essential to living in a scientific age and the mental discipline that comes from practice in inductive reasoning. Being able to draw conclusions independently from evidence would free individuals from a dependence on the intellectual authority of others, something that would serve them well as citizens in a democratic society.

Laboratories, as well as natural field sites, are places where students as potential future scientists can collect data that is important to their investigations. How early this initiation into the work of scientists should begin and how extensive early training in the actual practice of science should be are questions that are open to debate and discussion. A second purpose that can be served by having students model scientific inquiry is the development of citizens who may not become scientists themselves but who will be autonomous, independent thinkers.

Being able to draw conclusions independently from evidence would free individuals from a dependence on the intellectual authority of others, something that would serve them well as citizens in a democratic society. But during the first half of the twentieth century, these personal benefits began to take on less importance and science education came to be justified more explicitly in terms of its societal value. Education took on a more pragmatic bent as it sought to address the pressing problems that the rapidly growing country faced--issues related to immigration, urbanization, public health, and other socially-based problems.
