The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

Problem-based learning (PBL) is widely endorsed as a desirable learning method, particularly in science. Especially in light of the method's heavy demand on resources, evidence-based practice is called for. Rigorous studies of the method's effectiveness, however, are scarce. In Study 1, college students enrolled in an elementary physics course…

Compares the effectiveness of interactive free choice learning experiences to and combined with the lecture-demonstration approach in teaching sixth-grade children (N=50) to criticize and control experiments. Results contradict Piagetian theory regarding the importance of interactive experiences and exposure to materials in fostering these…
