Evaluation involves reflection, a process which promotes in-depth learning in science. Inquiry-based learning requires children to reflect on the evidence which they have gathered during their investigation. This evidence needs to be evaluated before reaching agreement on what conclusions can be drawn.
Evaluation of evidence requires the children to consider what patterns they can identify in their observations as well as how sure they are of the conclusions that they have drawn. Children need also to evaluate if more than one explanation can fit their observations and thus the possibility of having more than one possible answer.
Evaluation best takes place in groups as children bring different perspectives and interpretations of the same evidence. Evaluation also helps children to build arguments in favour of their conclusions and when considering alternative possible explanations put forward by others.
