In general, the statistical analysis using Paired Sample t test revealed that there was significant improvement on students' writing achievement after learning using TWPS and Peer editing strategy. Both high and low efficacy students experienced significant improvement in writing after learning using TWPS strategy. Meanwhile, another analysis using Independent Sample t test, the high and low self efficacy students of TWPS group got better achievement compared to those in Peer editing.
