Science Teaching

It is worth reading out what the OECD said in its report on PISA 2006:"““As the first major assessment of science, the PISA 2006 assessment establishes the basis for analysis of trends in science performance in the future and it is therefore not possible to compare science learning outcomes from PISA 2006 with those of earlier PISA assessments as is done for reading and mathematics. Indeed, the differences in science performance that readers may observe when comparing PISA 2006 science scores with science scores from earlier PISA assessments are largely attributable to changes in the nature of the science assessment as well as changes in the test design.””"
