We examined the development of numerical magnitude representations of fractions and decimals from fourth to 12th grade. In Experiment 1, we assessed the rational number magnitude knowledge of 200 Chinese fourth, fifth, sixth, eighth, and 12th graders (92 girls and 108 boys) by presenting fraction and decimal magnitude comparison tasks as well as…

This study aimed to extend the literature by examining how bystander intervention (i.e. when a witness to a bullying episodes does something to address the situation) varies with respect to the type of bystander intervention (i.e. direct intervention, emotional intervention, involving an adult, ignore) across victim status (friend, unknown),…

The current study investigated the associations among student perceptions of COVID-19 stress, internalizing problems, and school social support (teacher and classmate support) and how these relations differed across elementary/middle and high school students. Based on data from 526 4th- through 12th-grade students from a school district in the…

Tenets of the Boivin et al. (1995) social process model were reexamined with two longitudinal samples using both the original and contemporary analytic strategies. Study goals included reconstructing (e.g., quasireplicating) Boivin et al.'s (1995) original findings and evaluating hypothesized relations across both comparable and longer…

There has never been a more pressing need for students to learn how to evaluate scientific information online than during the COVID-19 outbreak. Information, misinformation, and disinformation spread quickly across online news and social media platforms. This misleading or incorrect scientific information about infectious diseases could lead to…

The purpose of this study was to determine if teachers are currently providing screencast video feedback for students as a means of formative assessment while they develop digital content. If this approach was already in place, the benefits of the practice were explored to support existing research on the method. If they did not use the…

The authors intended to (a) identify the association between gender or grade level and teachers' homework (HW) feedback and (b) examine the relationship between teachers' HW feedback, HW-related behaviors (e.g., amount of HW completed), and academic achievement. Four hundred fifty-four students (Grades 5-12) participated in this study. The results…

The purpose of this study was to investigate the reliability and validity of using a motivation inventory with music students in upper-elementary, middle, and high school. We used the middle/high school version of the MUSIC Model of Academic Motivation Inventory to survey 93 students in the 5th to 12th grades in one school. Our analysis revealed…

This Framework is built upon the foundation of the 2003 and 1997 "Massachusetts History and Social Science Curriculum Frameworks." Based in research on effective practice, it represents the contributions of members of the History and Social Science Curriculum Framework Review Panel, scholars who served as Content Advisors, and the more…

This article provides an initial comparison of the Principles and Standards for School Mathematics and the Common Core State Standards for Mathematics by examining the fundamental notion of slope. Each set of standards is analyzed using eleven previously identified conceptualizations of slope. Both sets of standards emphasize Functional Property,…

This study extends previous research on the long-term connections between motivation constructs in expectancy-value theory and achievement outcomes. Using growth mixture modelling, we examined trajectories of change for 421 students from 4th grade through college in their self-concept of ability (SCA) in math, interest in math, and perceived…

While most states require testing in social studies or civic education, two states attach consequences for students and schools based on required statewide civics exams. Lawmakers in Florida, in 2010, and in Tennessee, in 2012, approved legislation that holds students accountable for their civics knowledge. Students are taking the tests for the…

Research on bullying is an important avenue for understanding the social integration of students in special education. Focused on 3,305 students who self-reported victimization of two to three times per month or more, this study compared the pattern of verbal, relational, and physical bullying among students in general education and special…

The study reported here investigated the impacts of participation in 4-H on young people's interest and participation in science. Survey data were collected from relatively large and ethnically diverse samples of elementary and high school-aged students in California. Results indicated that although elementary-grade 4-H members are not more…

This study synthesized intervention studies focusing on instruction to improve fraction skills. Seventeen studies met the inclusion criteria: being published in English-language peer-reviewed journals or dissertations between 1975 and 2014, and targeting 3rd- through 12th-grade students struggling to learn mathematics. From the "Common Core…
