The researchers developed a reading and writing bifocal curriculum for grade 5 students from schools of rural Taiwan. The present study aims to examine the effects of the curriculum on students’ writing outcomes. A quasi-experimental design was adopted. The experimental group and control group were both composed of 28 grade 5 students recruited from schools in a remote area in Taiwan. All students received the intervention 5 sessions per week for 2 semesters. The total number of intervention sessions was 180. The experimental group received the bi-focal curriculum while the control group received current reading programs from their schools. Writing measures were collected at the beginning of the first semester, the end of the first semester, and the end of second semester. There were 3 major findings. 1. After conducting the bifocal program for 2 semesters, the progress of writing in the experimental group was better than that in the control group. There was no significant difference between the total number of characters and the average sentence length. 2. The bifocal program brought about quick observable growth of low-level tasks such as sentence length and total number of characters, in merely one semester. However, it took 2 semesters in the present study, to raise high-level skills like meaning expression. 3. With the involvement of the experimental intervention, students gradually got away from the “poor writer” group. The distribution of the outcome measures became more positively skewed. No such trend was observed in the control group.
