Primary Language Matters: Is There a Link Between Bilingual Education and English Language Learners’ Academic Achievement?

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.


Table of Contents

  • Research Design

  • Threats to Internal Validity

  • Threats to External Validity

  • Proposed Data

  • Proposed Data Analysis

Research Design

Quasi Experimental:Nonequivalent Control Group Design

Two groups: Designated treatment group (X1) and control group (X2) are pretested, exposed to a treatment (X), and posttested (O).

Symbolic Design:

O X1 O

O X2 O

Groups are not randomly assigned.


Threats to Internal Validity

  • History

  • Maturation

  • Testing – Pretest Sensitization

  • Instrumentation

  • Mortality

  • Statistical Regression

  • Differential Selection of Subjects

  • Selection-Maturation Interaction


Threats to External Validity

  • Ecological Validity

  • Generalizable Conditions

  • Pretest

  • Selection

  • Specificity of Variables

  • Multiple Treatments

  • Treatment Diffusion

  • Experimenter Effects

  • Reactive Arrangements/Participants Effects


Pretest & Posttest

  • Two Groups

  • Primary Language Assessment

  • Reading Assessments

  • Pretest Developmental Reading Assessment

  • Posttest Developmental Reading Assessment


Proposed Data Reading Comprehension Pretest and Posttest


Proposed Quantitative Data

Correlation between parents’ primary language attitudes and reading assessment.

Likert Scale Survey Question #4:

Is it important for your child to learn and maintain his/her native language?


Proposed Data Analysis

  • The chart shows that there is possibly a positive correlation between primary language attitudes and academic performance. The coefficient is 0.799414 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.
