Studies show that historically underserved students are disproportionately assigned to less qualified and effective teachers, leading to a “teacher quality gap.” Past analyses decompose this gap to determine whether inequitable access is driven by teacher and student sorting across and within schools. These sorting mechanisms have divergent policy implications related to school finance, student desegregation, teacher recruitment, and classroom assignment. I argue that analyses of the teacher quality gap that consider how teachers and students are sorted across labor markets offer additional policy guidance. Using statewide data from Texas, I show that teacher quality gaps are driven by sorting across school districts within the same labor market, but this finding differs depending on how “teacher quality” is defined.
Crafting Engaging Science Environments is a high school chemistry and physics project-based learning intervention that meets Next Generation Science Standards performance expectations. It was administered to a diverse group of over 4,000 students in a randomized control trial in California and Michigan. Results show that treatment students, on average, performed 0.20 standard deviations higher than control students on an independently developed summative science assessment. Mediation analyses show an indirect path between teacher- and student-reported participation in modeling practices and science achievement. Exploratory analyses indicate positive treatment effects for enhancing college ambitions. Overall, results show that improving secondary school science learning is achievable with a coherent system comprising teacher and student learning experiences, professional learning, and formative unit assessments that support students in “doing” science.

When integrated into online curriculum modules for students, educative curriculum materials (ECMs) can enhance teachers’ enactment of these modules. This study investigated (1) the use of digitally enhanced ECMs built into an online plate tectonics curriculum module by teachers with different backgrounds and teaching experience, (2) the relationship between teachers’ use of ECMs and student learning gains, and (3) teacher reflections on the value of the ECMs they used. We studied 26 teachers who taught middle and high school students (n = 1,098) by analyzing teacher log files automatically generated by the ECMs, teacher reflections collected with post-implementation surveys and interviews, student log files, and student learning gains from pretest to posttest. Results indicate that (1) there were large variations in the amounts and types of ECM features teachers accessed, (2) middle school teachers accessed significantly more ECM features than high school teachers p < .01, (3) students of teachers who used ECMs during class time made significantly higher learning gains than students of teachers who used them only before and/or between class time, p < .05, and (4) teachers most valued ECM features on student assessment. An overall non-significant, but positive, correlation between the total teacher interactions with ECMs and student learning gains was observed, r = 0.20, p = .32.more » « less

Abstract The Framework for K‐12 Science Education and the Next Generation Science Standards propose that students learn core ideas and practices related to engineering as well as science. To do so, students will need high‐quality curricular materials designed to meet these goals. We report an efficacy study of an elementary engineering curriculum, Engineering is Elementary (EiE) that includes a set of hypothesized critical components designed to encourage student engagement in practices, connect engineering and science learning, and reach diverse students. To measure the impact of the curriculum, we conducted a cluster randomized controlled trial in 604 classrooms in 152 schools in three states. Schools were randomly assigned to either the treatment curriculum or to a comparison curriculum that addressed the same learning goals but did not include several critical components. Results show that students who used the treatment curriculum (EiE) regardless of demographic characteristics outperformed students in the comparison group on outcome measures of both engineering and science content learning. The results show that curriculum design affects student‐learning outcomes.

This paper examines the use of collaborative curriculum design (co-design) as a strategy for supporting teacher professional learning and the implementation of an inclusive middle school computer science and digital literacy (CSDL) curriculum in three urban school districts. The curriculum is focused on students developing mobile apps that provide social and community good. The second year of the project has been dedicated to developing and piloting curriculum resources that support remote learning and culturally relevant pedagogy while the partner districts switched to remote and hybrid instructions. This study explores teachers’ professional learning experiences in the collaborative design of curriculum materials and piloting the curriculum at their own classrooms. The paper includes analysis of three data sets: (1) co-design meeting notes and teacher reflections; (2) semi-structured interviews with teachers who co-designed and piloted the curriculum; (3) student pre- and post-survey responses on their attitude and interest in learning CSDL. Preliminary results indicate that the co-design approach supplemented with one-on-one coaching has not only facilitated the curriculum development process but also fostered professional learning and collective capacity building for implementing the project curriculum in the partner districts. Findings from student surveys show that students perceived their understanding of, and interest in computer science and creating apps were slightly improved, regardless of gender.more » « less

Introduction Elementary teachers face many challenges when including reform-based science instruction in their classrooms, and some teachers have chosen to enhance their science instruction by introducing students to citizen science (CS) projects. When CS projects are incorporated in formal school settings, students have an opportunity to engage in real-world projects as they collect and make sense of data, yet relatively few CS projects offer substantial guidance for teachers seeking to implement the projects, placing a heavy burden on teacher learning.
Methods Framed in theory on teacher relationships with curricula, we prepared science standards-aligned educative support materials for two CS projects. We present convergent mixed methods research that examines two teachers’ contrasting approaches to including school-based citizen science (SBCS) in their fifth-grade classrooms, each using support materials for one of the two CS projects. Both are veteran teachers at under-resourced Title 1 (an indicator of the high percentage of the students identified as economically disadvantaged) rural schools in the southeastern United States. We document the teachers’ interpretations and use of SBCS materials for the CS projects with data from classroom observations, instructional logs, teacher interviews, and student focus groups.
Results One teacher adapted the materials to include scaffolding to position students for success in data collection and analysis. In contrast, the second teacher adapted the SBCS support materials to maintain a teacher-centered approach to instruction, identifying perceptions of students’ limited abilities and limited instructional time as constraining factors.
Discussion We discuss the intersection of CS projects in formal education and opportunities for engaging students in authentic science data collection, analysis, and sense-making. The two teachers’ stories identify the influences of school context and the need for teacher support to encourage elementary teachers’ use of SBCS instruction to supplement their science instruction.
