The purpose of the present study is to examine the degree to which the writing instruction using animations has effects on the writing performance of $4^{th}$ year elementary school students. This study also examined the effects of the animation-based writing instruction on the interest and confidence of those students. To this aim, the present study utilized a set of writing tests and questionnaires before and after the instruction. The data were collected from 63 elementary school students. The data were then analyzed using a series of statistical analyses. The results suggested that the students who received the writing instruction using animations performed significantly better on the writing test than those who received the textbook-based instruction. The results also suggested that those who received the animation-based instruction showed more positive interest and confidence on English and English learning. Finally, limitations of the present study and suggestions for further studies are discussed at the end of the paper.
