Reading achievement of English language learners in 50/50 and 90/10 two-way dual language programs

My study investigated the effects of two 50/50 and two 90/10 two-way dual language programs on the reading achievement of 76 English Language Learners (ELLs) from the end of third grade to the end of fourth grade. My study used both quantitative and qualitative data. Quantitative instruments included the Spanish Reading Texas Assessment of Knowledge and Skills (TAKS) and the Reading Proficiency Test in English (RPTE) scores. Qualitative instruments included structured interviews with the two-way dual language program coordinators/administrators. The quantitative results of my study showed there were no statistically significant differences between the two groups on the Spanish Reading TAKS by the end of fourth grade. The 50/50 students did make statistically significant gain scores on the Spanish TAKS from the end of third grade to the end of fourth grade, but the 90/10 students did not make statistically significant gains. Both groups were performing above the State averages on scale score and passing rate on the Spanish Reading TAKS. On the RPTE, the results of my study showed there were no statistically significant differences between the two groups by the end of fourth grade. Both the 50/50 and the 90/10 students made significant gain scores on the RPTE from third grade to fourth grade. The 50/50 students made a greater gain on the RPTE than then 90/10 students did. Both groups of dual language ELLs had higher percentages of students in the advanced high rating than the State on the RPTE. The qualitative results showed that several elements were necessary to implement and maintain these two-way dual language programs. These elements included: planning, resources, parental support, qualified teachers, and supportive administrators.
