ABSTRACT
In this chapter we discuss a case study of curriculum reform that revealed some promising patterns for high school physical science. The case study involves helping students understand the structure of matter and was conducted by Eylon and her colleagues in Israel (Ben-Zvi, Eylon, & Silberstein, 1986a, 1988; Linn, Songer, & Eylon, 1996; Margel, Eylon, & Scherz, 2008).
