TABLE OF CONTENTS Research Design Threats to Internal Validity Threats to External Validity Proposed Data Pre-Test/ Post-Test Results Proposed Data Analysis and Correlation Parent and Student Surveys References
RESEARCH DESIGN Research Design: Quasi-Experimental Design – Nonequivalent Control Group Design Two groups: – Symbolic Design: O X 1 O O X 2 O – (O) Pre-test, (X 1 ) Treatment for Group 1, (X 2 ) Treatment for Group 2, (O) Post-test Two groups of students at risk for limited English literacy achievement will be pre-tested, with Group 1 being exposed to a treatment (bilingual small group literacy instruction) and then post-tested. Individual selection will not be random. Participants are in existing classroom groups according to the Dual Language 50/50 model. Group assignment, however, WILL be random.
THREATS TO INTERNAL VALIDITY History Maturation Testing/ Pre-Test Sensitization Instrumentation Mortality Differential Selection of Subjects
THREATS TO EXTERNAL VALIDITY o Ecological: This particular Dual Language Model is not present in all schools serving ELLs. o Generalizable Conditions o Pre-test Treatment o Experimenter Effects o Specificity of Variables o Reactive Arrangements/ Participants Effects o Compensatory Rivalry o Placebo Effect – Parent Surveys
