The researcher used many materials and tools: A written test of orthography skills, a program employing blended learning, a teacher's guide. The study sample Asmaa Elementary Co-school (C) for Refugees was purposively chosen. The school included four 2nd grade classes. The experimental and control groups were randomly assigned. The experimental group consisted of (34) students who studied orthography skills using the blended learning-based program, while the control group consisted of (34) students who studied orthography skills using the conventional method. The researcher adopted the quasi-experimental approach. The study main findings: There were statistically significant differences at the significance level (α = 0.05) between the mean scores of the experimental group students and those of their counterparts of the control group in the post application of the orthography skills test. The researcher recommended: 1) It is necessary that the program prepared by the researcher be disseminated and used in schools. 2) It is necessary that blended-learning be adopted for developing orthography skills at the low elementary stage. 3) It is necessary to provide an appropriate instructional environment (such as computers, the Internet, LCDs) so as to teach using blended learning in the educational institutions. 4) It is necessary to hold training courses for the low elementary stage teachers to train them on how to employ blended learning in the educational process.
