  1. IMMERSION VERSUS BILINGUAL LITERACY INSTRUCTION Which is a better solution for our non-English speaking students? Susana Pinto Spring 2010

  2. TABLE OF CONTENTS • Research Design • Threats to Internal Validity • Threats to External Validity • Proposed Data • Pre-test and Survey Results • Proposed Data Analysis and Correlation • References

  3. RESEARCH DESIGN • Nonequivalent Control Group Design: Two groups are pretested, exposed to a treatment (x), and post tested (o). • Symbolic design: • O X1 O • O X2 O

  4. Threats to Internal Validity History: During allotted time there may be distractions, i.e. weather, phone in classroom, fire drills, etc. Maturation: Students over time may lose interest or may be embarrassed to be in the group and not pay attention. Testing/Pre-test Sensitization: Students can expect what will be on the post-test since there will be a pre-test to asses the students. Instrumentation: Students might get bored of taking the surveys or parents might not fully understand what is being asked. Mortality: Students might be absent or move away. Differential Selection of Subjects: Each group is in a different school. One group will be given material in their native language and the other group will only be given English material.

  5. Threats to External Validity • Ecological Validity: The results of this study can be generalized with other students that are facing the same language barrier. • Selection Treatment Interaction: Students were not randomly selected. Both groups were selected because they are learning to read the English language. • Multiple Treatment: The researcher is using two treatments, immersion / bilingual lesson plans. • Experimenter Effects: Researcher does present a threat due to the fact that they have a personal connection with the topic. • Reactive Arrangements/Participants Effects: This could possibly be a threat to the study because since this is new for the students they will do better than on ordinary circumstances, i.e. Novelty Effect.

  6. Proposed Data A question that was given to parents on a survey: • How often do you read to your child in English? • Pre-Test to each student in both groups - G:\WHAT AM I WORKSHEET.doc

  7. Pre-test & Parental Survey ResultsDo parents reading to their child in English help literacy skills?

  8. Proposed Data Analysis & Correlation From the previous Bar Graph we can see that the more a parent reads to their child in English the higher the pre-test score is. This is a good indication that immersing the student in English language has higher benefits than bi-lingual instruction. Also, our correlation chart shows a high positive correlation. The Rxy is 0.94.
