Developing Situated Measures of Science Instruction Through an Innovative Electronic Portfolio App for Mobile Devices: Reliability, Validity, and Feasibility.

ABSTRACT: Adoption of new instructional standards in science demands high-quality information about classroom practice. Teacher portfolios can be used to assess instructional practice and support teacher self-reflection anchored in authentic evidence from classrooms. This study investigated a new type of electronic portfolio tool that allows efficient capture of classroom artifacts in multimedia formats using mobile devices. We assess the psychometric properties of measures of quality instruction in middle school science classrooms derived from the contents of portfolios collected using this novel tool-with instruction operationalized through dimensions aligned to the Next Generation Science Standards. Results reflect low rater error and adequate reliability for several dimensions, a dominant underl
