This document describes the model used by the New York State Education Department (NYSED) to measure student growth for institutional accountability in New York State for the 2016/17 school year. In 2016/17, growth models were implemented for institutional accountability in Grades 4-8 ELA and mathematics. All models are based on assessing each…

This document describes the model used by the New York State Education Department (NYSED) to measure student growth for institutional accountability in New York State for the 2015/16 school year. In 2015/16, growth models were implemented for institutional accountability in Grades 4-8 ELA and mathematics. All models are based on assessing each…

Many school districts across North America have turned to a framework for curriculum design and instruction called "Understanding by Design." Included in the framework is a call for teachers to create "essential questions" that provocatively ask students to consider and learn the "big ideas and core processes within the…

Drawing on the self-system model, this study conceptualized school engagement as a multidimensional construct, including behavioral, emotional, and cognitive engagement, and examined whether changes in the three types of school engagement related to changes in problem behaviors from 7th through 11th grades (approximately ages 12-17). In addition,…

Scientists regularly evaluate alternative explanations of phenomena and solutions to problems. Students should similarly engage in critical evaluation when learning about scientific and engineering topics. However, students do not often demonstrate sophisticated evaluation skills in the classroom. The purpose of the present study was to…

Previous research has identified various factors that contribute to readers' comprehension of expository texts, including strategy expertise, language proficiency, prior knowledge, and more recently, readers' beliefs about knowledge. This study addresses the need to understand the relative contributions of these predictors to readers'…

The purpose of this study was to investigate the effect of scientific studies on students' scientific literacy and attitude towards science course. For the study, a middle school science study group was established by randomly selecting 30 students from the 6th, 7th, and 8th grades. Participating students were given information about the…

Mediation analysis is a statistical approach used to examine how the effect of an independent variable on an outcome is transmitted through an intervening variable (mediator). In this article, we provide a gentle introduction to single-level and multilevel mediation analyses. Using single-level data, we demonstrate an application of structural…

This study examines factors related to the sustainability of SimCalc Mathworlds (SCMW), a technology-infused mathematics curriculum. We surveyed middle school teachers one year after their participation in a randomized trial where they were introduced to SCMW curriculum, to identify factors related to their continued use of the materials in ways…

Behavioral science researchers routinely use scale scores that sum or average a set of questionnaire items to address their substantive questions. A researcher applying multiple imputation to incomplete questionnaire data can either impute the incomplete items prior to computing scale scores or impute the scale scores directly from other scale…

Background: Although psychological disengagement is a well-documented phenomenon in the academic setting, the attempts to identify its predictors are scarce. In addition, existing research has mainly focused on chronic disengagement and less is known on the determinants of situational disengagement. Aims: The purpose of the present study was to…

This work assessed the efficacy of a middle-school-based mentoring program designed to increase student use of self-regulated learning (SRL) strategies, self-efficacy for and the perceived usefulness of SRL as well as mathematics and language achievement. A longitudinal cluster randomized trial study design obtained evidence that found…

The third study by the "Southern and Eastern Africa Consortium for Monitoring Education Quality" (SACMEQ) revealed that achievement in mathematics among Grade 6 children in Mozambique is declining, and gender differences favouring boys persist. This study examined the contribution of parents, economic resources and cultural factors on…

This report is a follow-up to "Gaining Ground in the Middle Grades" (Williams, Kirst, Haertel, et al., 2010). That study specified a comprehensive set of actionable practices that differentiated higher academic achievement among 303 middle grades schools in California. In doing so, the study provided a compelling and coherent account of…

This paper presents the research and methodology and analyses used for the "Gaining Ground in the Middle Grades" research. This appendix contains the following sections: (1) Overview; (2) Constructing the Survey Data File; (3) Constructing Composite Independent Variables (Subdomains); (4) Constructing Longitudinal Outcome Variables; (5)…
