Project Activities
The researchers will conduct secondary analyses of the National Longitudinal Transition Study-2 (NLTS2) dataset to explore relationships between school-based interventions (e.g., inclusion, course taking, modifications and accommodations, tutoring, technology aids) and outcomes (e.g., achievement, graduation, postsecondary enrollment, employment) for students who are deaf or hard of hearing.
Structured Abstract
Setting
NLTS2 includes students from across the United States.
Sample
The researchers will use the NLTS2 dataset, which includes a nationally representative sample of secondary students with disabilities. The researchers will focus on students who are deaf or hard of hearing.
There is no intervention.
Research design and methods
The project is examining an extant database for relationships between school-based interventions and a variety of outcome variables while utilizing propensity scoring methods to adjust for baseline differences among students. After adjusting, the researchers will conduct analysis of covariance and regression analyses to explore relationships between interventions and outcomes.
Control condition
Due to the nature of the research design, there is no control condition.
Key measures
For data collection purposes, the NLTS2 study used parent telephone and mail surveys, school staff surveys, student transcripts, and direct and alternate assessment of student abilities in math, vocabulary, science, and social studies. The dataset provides numerous student-level variables related to high school and post-school outcomes including high school completion, postsecondary enrollment, employment, independent living, and community participation.
Data analytic strategy
The researchers will conduct exploratory analyses and use data reduction techniques to decrease the number of variables used in the analyses. Exploratory analyses will be conducted to identify the covariates to be used in the propensity score analysis. After calculating propensity scores, the researchers will conduct analysis of covariance and regression to explore relationships between interventions and outcomes.
