Research on teaching practice has recently gained attention as an effective lever for improving student engagement and achievement. Recent studies have shown that even more than years of teaching experience or degree held, the instructional practice that occurs in K-12 classrooms is the best predictor of student learning. Given the limited amount of time and resources available for preparing new teachers, identifying and helping novices take up a small set of effective, content-specific practices, has great potential for improving the education of students in our nation's schools.

This program of researching draws on the emerging work of core instructional practices. Fueled by work with the Core Practice Consortium (https://www.corepracticeconsortium.com/), this series of studies focuses specifically on how science teachers learn and engage core practices like facilitating sensemaking discussions and how students participate in these experiences.

Texts play a critical role in science research and science classrooms, yet most K-12 textbooks have failed to represent the epistemic elements of the science disciplines, including the justification of claims or references to empirical data. This line of research investigates students' reading experiences when engaging alternative text types that are more epistemologically considerate, that is, texts that better convey both what we know and how we know it to be true.

Using narratives of historical experiments, these brief narrative texts have been shown in initial randomized trials to result in more interest from students, equivalent comprehension of core biology ideas, and higher performance on transfer tasks when compared to traditional textbook accounts. Current research is focusing on how students engage these alternate text types in group discussions and the impact of their use over the course of an entire year.

As a result of these studies, we look to create a set of historical narratives that are more epistemologically considerate than traditional science texts that can be used, in alignment with the Next Generation Science Standards and the Common Core Literacy Standards for Science, in middle and high school science classrooms.
