Even though media literacy education has grown in the United States and around the world, policymakers still lack knowledge about the scope and depth of implementation of media literacy learning activities in the elementary and secondary grades. This study reports how the Media Literacy Implementation Index (MLI) was developed and validated using a quota sample of stakeholders from across all school districts and local communities in Rhode Island. Using an established theoretical framework for media literacy, we first constructed a scale to examine the likelihood that learners may encounter a set of media literacy learning activities. Multiple methods were then used to assess reliability and validity of the instrument including cognitive pretesting, think aloud protocols, a content validation of MLI learning activities in relation to national education standards documents, and statistical validation including principal components analysis to assess internal consistency, reliability, and validity. An easy-to-implement measure of the scope and depth of media literacy education in elementary and secondary schools will be useful to diverse stakeholders including educators, school leaders, librarians, parents, community members, and elected public officials.

Interest in media literacy education is increasing across the United States and around the world but little is still known about the prevalence of various instructional practices used to implement it in elementary and secondary schools. Surveys and semi-structured interviews with a statewide quota sample of education stakeholders included school leaders, educators, librarians, elected public officials, parents, and members of the community in all 24 school districts in Rhode Island. Results show that only a few instructional practices are implemented with most or nearly all students in the state. However, the implementation of various media literacy instructional practices varied considerably from one community to another but these differences were not due to the size of the community, its geographic location, or its socioeconomic status. Nearly half the variance in instructional practices can be accounted for by obstacles including technology limitations, school policies, academic priorities, perceptions of students, and educator response.
