For twenty years, social constructivism has been a paradigm in science teaching and not an easy bedfellow for piagetian constructivism, even though both have had the same thing in mind… a study of the learner. For this reason we attempt to find connections and bridges between them so that both may be enriched, to the benefit of science teaching.
