In this study, the authors examined the survivability, or persistence over time, of overall science instruction for English learners (ELs) in treatment and control classrooms within a field-based, quasi-experimental grant-funded project in the United States. The project's goal was to increase ELs' science and language achievement through…

The purpose of this quasi-experimental study was to examine attitude and achievement among fifth grade students participating in inquiry and lecture-based forms of instruction through interactive television. Participants (N = 260) were drawn from registered users of NASA's Digital Learning Network[TM]. The first three levels of Bloom's Revised…
