Primary Language Matters: Is There a Link Between Bilingual Education and English Language Learners’ Academic Achievement? 1 Nury Rodriguez Education 7202: Seminar in Applied Theory and Research II Fall 2010
Method Participants: 20 first grade students at P.S. X in Brooklyn, New York. Students are Hispanic. Two groups of students will be involved. Parents of participating students. Teachers and administration.

Research Design Quasi Experimental: Quasi Experimental: Nonequivalent Control Group Design Two groups: Designated treatment group (X 1 ) and control group (X 2 ) are pretested, exposed to a treatment (X), and posttested (O). Symbolic Design: O X 1 O O X 2 O Groups are not randomly assigned.

Likert Scale Survey Question #4: Is it important for your child to learn and maintain his/her native language? The coefficient is rxy.
Proposed Data Analysis The chart shows that there is possibly a positive correlation between primary language attitudes and academic performance. The coefficient is rxy. The high X scores are paired with the high Y scores. The coordinates are close to the trend line of best fit, and it is fair. Therefore, if attitudes and support of parents concerning the use of the primary language are positive, students reading comprehension scores are high.
