After 25 years with small to moderate gains in performance in mathematics, scores on the National Assessment of Educational Progress (NAEP) main assessment declined between 2013 and 2015 in Grades 4 and 8. Previous research has suggested the decline may be linked to the implementation of the "Common Core" state standards. In this…

Studies aiming to make cross-cultural comparisons first should establish measurement invariance in the groups to be compared because results obtained from such comparisons may be artificial in the event that measurement invariance cannot be established. The purpose of this study is to investigate the measurement invariance of the data obtained…

The aim of the study was to investigate students' views of model evaluation through the lens of personal epistemology. We developed an integrated analytical framework by combining a developmental framework, including absolutist, multiplist, and evaluatist, with a multi-dimensional framework, including limits of knowing, certainty of knowing, and…

Developing critical thinking practices among young learners through mathematics education is a topic of attention for mathematics education research community. Learners' critical thinking concerning cognitive and social aspects of their mathematics education have been explored in several research studies. However, learners' critical thinking…

Making sense of data is fundamental to science. Yet, the form in which data are represented can make their interpretation challenging for students. We introduce an activity that transformed a data table into an embodied artifact. The activity helped 8th grade students interpret the data to find that cold water warmed "fast-then-slow," in…

Tasks involving real-world contexts offer opportunities for teachers to engage students in mathematical practices (Standards for Mathematical Practice; NGA Center and CCSSO 2010). The practice of reasoning abstractly and quantitatively requires students to decontextualize and contextualize a task. Decontextualizing a task involves representing it…

Using the High School Longitudinal Study of 2009, we examine the association between taking Algebra I by the eighth grade and students' later achievements and advanced mathematics course-taking. To explore our research questions, we employ three distinct methods--regression analysis, fixed effects models, and propensity score matching. In all our…

It is widely assumed that teachers play a key role in providing high-quality learning opportunities to students and fostering students' learning. Yet it is still unclear how specific teacher knowledge facets as part of their professional competence contribute to classroom processes and learning outcomes. Focusing on mathematics education at the…

In this article, we describe how eighth-grade students and teacher candidates used sound and listening to remix and attune themselves (Stewart, 2011) to the dystopian novel "Fahrenheit 451" by Ray Bradbury (2011). We situate our sound inquiries in relation to critical literacy (Vasquez, Janks, & Comber, 2019; Wargo, 2019) and sound…

The aim of this study is to determine the evaluations of eighth grade gifted students towards cloning and to examine the argument structures formed by gifted students. The study was carried out using a case study design, which is one of the qualitative research method designs. The study group of the research consists of 24 gifted students studying…

The current study used latent profile analysis to find subgroups of youth based on bullying participant roles and then compared subgroups on the five bystander intervention steps (Notice, Interpret as an emergency, Accept Responsibility, Know how to Intervene, and Act). The sample included 641 fourth-eighth grade students (44.6% boys) who…

The purpose of this study was to determine if attending a single-sex, STEM-focused school was related to science and mathematics achievement among a sample of African American and Latina eighth-grade girls in one school district. A nonequivalent group, post-test only design was utilized in the study to mitigate the effects of selection bias. We…

The aim of this study was to examine the number sense performance of 8th-grade Turkish students. In this study, the students' performances on number sense were also examined in terms of gender, school location, parents' education level, maths achievement, perceived student satisfaction with the maths teacher, perceived importance of maths and…

Based on theories of emotion contagion and social appraisal in interpersonal affect transfer and the control-value theory of achievement emotions, the present study examined associations between students' perceptions of peer emotions and their own self-perceived emotions in English as a foreign language (EFL) classrooms. Data were collected from…

Classroom music teachers in England design their own music curricula for Key Stage 3 (11 - 14 year olds, 6th - 8th Grades). These curricula are designed in a context where policymakers define, regulate and legitimate curriculum formulations. This study traced curriculum development in England, where government has validated a policy driven…
