The research design for this project is both longitudinal and cross-sectional, and is designed to generate evidence that is descriptive [design research], associative/correlational [analytic essay], causal [experimental methods and statistical modeling], and synthetic [meta-analysis].
This project collects original data through a variety of methods including assessments of learning/achievement tests, observation, and survey research including paper and pencil self-completion questionnaires, structured interviewer-administered questionnaires [face-to-face, computer assisted personal interviews (CAPI), telephone, and computer assisted telephone interviews (CATI)], semi-structured/informal interviews (face-to-face, and telephone), and imaging. Instruments and measures include structured interview questions, surveys, multiple-choice tests of knowledge, keyboard and mouse actions. Instruments used include WIAT-II, WASI, WMTB-C, MARS-E, KeyMath. There are plans to make originally-collected data available for use by others. Plans for analysis include general linear modeling, hierarchical regression, and classification.
