Videotapes and time-indexed fieldnotes from across the instructional unit provided the primary source of data to capture and illustrate how the learning environment she structured fostered PDE for her students (Jordan & Henderson, 1995). These video data were coded for the implementation of different aspects of inquiry by the teacher or students, student engagement, and scaffolding for language learning. Such an approach provided a basis for characterizing the learning environment structured by the teacher and the instructional approach she used. It also allowed for cataloging student engagement across the instructional unit. Students were also pre-post tested on science content and their views on science to measure learning. Together, these data provide the basis for claims related to how the nature of the hybrid learning environment related to the classroom implementation of an actual investigation provided for a shift from initial to deeper PDE.
