This study tested competing theories about the effectiveness of different instructional sequences for learners with different levels of prior knowledge. Across two classroom experiments, undergraduates learned about noncovalent interactions in biochemistry by either receiving explicit instruction before problem-solving (I-PS group) or engaging in…

Transfer of learning is a fundamental goal of education but is challenging to achieve, especially where far transfer to remote contexts is at stake. How can we improve learners' flexible application of knowledge to distant domains? In a counterintuitive phenomenon termed the "derring effect," deliberately committing and correcting errors…

Recent research about the learning of science has suggested that misconceptions are not replaced by scientific conceptions and extinguished once conceptual change has occurred. Rather, misconceptions still exist alongside the acquired scientific conceptions and must be suppressed in order to use scientific conceptions. Our goal in this review is…
