It would be difficult to support any claim that problem solving is not an important goal in the

teaching of science.

Scientists by their very nature are problem solvers.

Rather, we contest the viewpoint that problem solving is the most important

goal in the teaching of science.

Science is a multi-faceted discipline.

There are many ways to “do” science.”

There are many ways to learn science.

Important Questions to Consider…

specialist secondary science specialist secondary science teachers would probably describe teachers would probably describe

their main task as helping their main task as helping students to learn new ideas and students to learn new ideas and explanations regarding natural explanations regarding natural

children should…children should…

1. understand that scientists are successful in developing understanding the world even though they do not have a fail-safe method, but that science is fallible

2. acknowledge scientific knowledge as the best we have, and therefore accept that it is rational to trust in expert knowledge (thus limiting skepticism to a justified level)

3. adopt many of the critical and creative attributes of scientists (giving students the skills to take seek and evaluate evidence and to take part in reasoned debate)
