This article reports the results of a randomized control trial of a semester-long intervention designed to promote ninth-grade science students' use of text-based investigation to create explanatory models of biological phenomena. The main research question was whether the student participants in the intervention outperformed the students in the…

Urban school districts face a dilemma in providing professional development support for teachers in transition to the Next Generation Science Standards (NGSS). Districts need to maximize the quality and amount of professional development within practical funding constraints. In this paper, we discuss preliminary results from a…

These appendices accompany the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the…

This paper presents findings from a randomized controlled trial (RCT) testing the impact of a novel coaching approach utilized as one element of the Double Check cultural responsivity and student engagement model. The RCT included 158 elementary and middle school teachers randomized to receive coaching or serve as comparisons; all participating…

The RCT included 158 elementary and middle school teachers randomized to receive coaching or serve as comparisons; all participating…

Two professional development (PD) models for teachers were compared on teacher and student outcomes. Special education teachers participated in Literacy Learning Cohorts (LLC), a PD innovation designed to improve content and pedagogical knowledge for providing reading instruction to upper elementary students with learning disabilities. The LLC,…

This study investigated public school principals' reports of professional development implementation at the school level while working in different state- and local-level contexts (state accountability level, geographic locations, socioeconomic status, demographics, and grade levels). I attempted to measure principals' reported changes in levels…

It is a common knowledge that student achievement is a product of multiple individual and environmental factors. The literature developed various models to organize and explain the relationship between some of these variables and student learning which translates into student achievement. Yet, no comprehensive model is able to capture all possible…

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two…

The Standards for Effective Pedagogy and Learning (CREDE, 2014) specify five "transnational universals of teaching" that are especially effective for the rapidly growing population of English language learners in North America. CLASSIC is an evidence-based, CREDE-aligned model of teacher education for classroom educators of English…

Objectives: Group-randomized designs are well suited for studies of professional development because they can accommodate programs that are delivered to intact groups (e.g., schools), the collaborative nature of professional development, and extant teacher/school assignments. Though group designs may be theoretically favorable, prior evidence has…

The purpose of this study is to evaluate, using a randomized experimental design, the efficacy of TERC's "Using Data" program to change teacher behavior and improve student learning outcomes. The "Using Data" intervention provides professional development and technical assistance to teachers to help them use data…

Effective instructional materials can be valuable interventions to improve student interest and achievement in science (National Research Council [NRC], 2007); yet, analyses indicate that many science instructional materials and curricula are fragmented, lack coherence, and are not carefully articulated through a sequence of grade levels (AAAS,…

"Success for All" (SFA) is one of the best known and thoroughly evaluated school reform models. Further evaluation of the initiative is especially important for two reasons. First, the program model has continued to evolve over time, with a greater emphasis placed on the use of engaging technology in the classroom and on the deployment…
