More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge was not the ability to retain facts or apply previous knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (though the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas.

The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues. The college students had cultivated the ability to ask questions, the foundation of critical thinking. They had learned how to learn.

Museums and other institutions of informal learning may be more suitable to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit—asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit.

This type of learning is not limited to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form and pursue their own questions and too much ground to cover in the curriculum. But people must acquire this skill somewhere. Our society depend on them being able to make critical decisions about their own medical treatment, says, or what we must do about global energy needs and demands. For that, we have a robust informal system that gives no grades, takes all comers, and is available even on holidays and weekends.
