The present study attempted to examine the effect of using computer edutainment on developing 2nd graders' writing skills. The study comprised thirty-second year primary stage enrolled in Bani Hamad primary governmental school, Minia governorate. The study adopted the quasi-experimental design. Thirty participants were randomly assigned to one group and they were taught through a suggested computer edutainment program. Data were gathered and analyzed using both quantitative and qualitative instruments. A pre post electronic writing test, a pre post paper and pencil writing test, a writing scoring rubric, a vocabulary acquisition test, a self-assessment checklist, a writing skills strategies and concepts checklist, writing samples, a writing development record, and reflection logs were used in the study. Findings indicated that participants showed significantly higher levels of writing samples in the area of content and ideas, organization and form, style, and convention. Findings also showed significantly higher levels of vocabulary acquisition. Participants' writing samples and the writing development record showed that they internalized the writing strategies and concepts they were taught, and transferred them to their independent writing. Participants also showed that they moved from the emergent stage of writing to the conventional one. The improvement of pupils writing as demonstrated by multiple measures suggests that computer edutainment is an effective way for developing 2nd primary graders' writing skills in one of the governmental schools.
