This study investigated the effect of the metacognitive instruction in which students' epistemic cognitions were explicitly addressed, on tenth-grade students' conceptual understandings regarding force and motion. The participants of the study included 107 (49 female, 58 male) tenth-grade students at two public high schools. A quasi-experimental…

Hrin, Tamara N.; Fahmy, Ameen F. M.; Segedinac, Mirjana D.; Milenkovic, Dušica D. – Research in Science Education, 2016
Many studies dedicated to the teaching and learning of organic chemistry courses have emphasized that high school students have shown significant difficulties in mastering the concepts of this discipline. Therefore, the aim of our study was to help students to overcome these difficulties by applying systemic synthesis questions, [SSynQs], as the…
