“…Questions like what constitutes good thinking or how to foster students' thinking in school in general, and in science lessons in particular, have been increasingly discussed in the educational literature over the past few decades (Beyer, 1988;Costa, 1985;Glaser, 1984;Pogrow, 1988;Sternberg, 1987;Zohar, 1999Zohar, , 2004aZohar and Dori, 2003).
