Özet:

The purpose of the present study is to determine whether Web-based Writing Instruction (WBWI) has any influence on the writing quality of Iranian EFL learners. Two groups of EFL learners who were studying English in an English Language Institute participated in the experiment. They were enrolled in an advanced writing course. Before instruction, both groups were pre-tested through writing essays. T-test results illustrated significant differences between two groups in writing ability. The experimental group made too many errors and had many writing problems. Both groups studied the same in-class material, and were given the same assignments and assessment. In addition, the experimental group used an online course, which was provided for them through establishing a so-called website, from home. Experimental students posted their points, wrote short essays and posted stories in the comment section of the so-called website. They located information in sites like “Yahoo Movies” and “webMD”. They processed their essays and checked their spelling through Microsoft Office Word (2007). At the end of the experiment, both groups were post-tested through writing an essay. ANCOVA results showed considerable differences between two groups. The experimental group made more gains as a result of web-based instruction. They became more proficient, and made few errors.
