Trends in International Mathematics and Science Study (TIMSS) is an international comparative study designed to measure trends in mathematics and science achievement at grades 4 and 8, as well as to collect information about educational contexts (such as students' schools, teachers, and homes) that may be related to student achievement. TIMSS has…

The growth of a STEM-focused economy has intensified the focus on developing kindergarten through grade 12 (K-12) students' STEM competencies and on the STEM practices of K-12 STEM teachers. The present study utilised secondary analysis of nationally-representative STEM teacher survey data to examine the ways in which middle grades teachers'…

This paper reports on students' experiences of describing and representing variation in hypothetical data. Fifty-six students (8-9 years-old) experienced collecting and working with quantitative data for two years as part of a STEM education project. The task described here was an end-of-year survey question, with three parts about a hypothetical…

Background: Schools are important contexts for preventing sexual violence (SV) among adolescents. Evaluating whether programming is effective requires surveying youth about SV experiences. However, school communities often have concerns about asking students, particularly those in middle school, about these experiences. This study sought to…

This study examined the longitudinal changes in kindergarten demographics and child outcomes by comparing data from the Early Childhood Longitudinal Survey (ECLS-K) 1998 and 2011 cohorts. Results demonstrated that there were significant changes in kindergarten in general and with regard to FDK and HDK schedules between 1998 and 2011. These…

We assessed measurement invariance (MI) and cohort trends for five social and emotional learning (SEL) measures across four administrations (2013, 2016, 2019, 2022) of a statewide student survey including grades 5, 8, 9, and 11 (n = 626,082). The MI models were compared using conventional fit statistics and the root mean square error of…

Engagement and academic achievement are generally correlated among elementary school students without learning disabilities (LDs). However, it is unclear if this pattern holds for students with LDs, who have lower achievement and engagement than their peers. This study examined whether links between achievement and student-reported behavioral…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

In European studies, immigrant-origin adolescents report more mental health symptoms than natives do. The school is an important developmental context for them, and more research is needed about how their school experience is related to their mental health symptoms, and whether these relations vary by group. The aim of this study was to assess the…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study designed to measure trends in mathematics and science achievement at the fourth and eighth grades, as well as to collect information about educational contexts (such as students' schools, teachers, and homes) that may be related to student…

Engagement and academic achievement are generally correlated among elementary school students without learning disabilities (LDs). However, it is unclear if this pattern holds for students with LDs, who have lower achievement and engagement than their peers. This study examined whether links between achievement and student-reported behavioral…

This study outlines the assessment culture of mathematics in Finnish basic education (grades 6 and 9) based on a nationally-sampled dataset (N = 673). The study draws on the theoretical framework of assessment cultures as defined through cultures of learning, compliance and fear. We approach the assessment culture of mathematics through the…

In this study, methodology and theory were linked to explicate the nature of education practice within schools facing exceptionally challenging circumstances (SFECC) in Trinidad and Tobago. The research design was an iterative quan>QUAL-quan>qual multi-method research programme, consisting of 3 independent projects linked together by overall…

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…
