(main effects) 3. Do grade 6–8 ML students in specific popula on subgroups show greater growth in English reading skills when receiving instruc on incorpora ng Bridges (treatment group) than the level of growth achieved by a comparable group of students in those popula on subgroups receiving instruc on NOT incorpora ng Bridges (i.e., following tradi onal instruc onal prac ce) (comparison group)?
