This special issue of the International Electronic Journal of Elementary Education (IEJEE) is devoted to one of the most current and important educational topics of our time: Learning and Instruction in the Natural Sciences (K-10 focus). Drs. Florencia K. Anggoro and Benjamin D. Jee of the College of the Holy Cross, USA, have done a great job as special issue editors. I am very grateful for the scientific editorialship they have accomplished as two active scholars in their field.
