The purpose of this study was to examine the effects of a number line intervention with supported self-explanation on student understanding of fraction magnitude and quality of explanation. Participants were three U.S. middle school students with significant behavior problems. Participants were given eight lessons containing explicit instruction…

This study evaluated direct and indirect effects of the Family Check-Up Online (FCU-O) across two distinct randomized trials with middle school youth and families. The FCU-O is a digital health adaptation of the Family Check-Up that is delivered in a brief, online format with supportive coaching. The FCU-O was delivered to parents of middle school…

Word problem-solving is one major area in mathematics that has been identified as being particularly challenging for students, specifically for those with learning disabilities (LDs) and emotional and behavioral disorders (EBD). This study aims at evaluating the effects of a strategic math intervention with concept maps on the ability to solve…

Twice exceptional (2e) students are students who are both gifted and have a disability. At the intersection of exceptionality and race, twice exceptional students from racially minoritized communities may experience behavioral difficulties in schools. In this article, we provide information for educators as well as school and district…

The main objective of this four-year empirical research project has been to develop the experimental design skills of 12-16 year-old Hungarian pupils in Grades 7-10 of junior high school through guided inquiry, using six chemistry experiment worksheets each school year. Group 1 (control group) and Group 2 follow step-by-step instructions, but…

Students with reading difficulties frequently struggle succeeding in middle school courses due to poor early reading and language skills. Research suggests that students with reading difficulties and comorbid behavioral concerns may have difficulties making appropriate gains when exposed to academic instruction. This study examined the extent to…

We adapted the Family Check-Up Online (FCU-O): 1) to support families coping with pandemic-related stressors to prevent behavioral and emotional problems among middle school youth, and 2) for smartphone delivery to increase access and reach during the COVID-19 pandemic. This study evaluated the direct and indirect effects of the adapted FCU-O at…

During the past 20 years, numerous studies examining the use of problem posing in mathematics instruction have documented positive outcomes in terms of students' problem-solving skills, creativity, and attitudes and beliefs regarding the study of mathematics. However, despite these promising results, problem posing in mathematics instruction has…

This single-case study assessed the effectiveness of a mnemonic pegword strategy designed to enhance the multiplication fact fluency of three 6th-grade students who demonstrated persistent learning difficulties in mathematics. A nonconcurrent multiple baseline across subjects design was utilized, incorporating 3-5 baseline sessions followed by…

Check-in/check-out (CICO) is a Tier 2 behavioral management system in the School-wide Positive Behavior Support (SWPBS) framework, which is widely used in Western schools. However, this system is not currently used in public schools in mainland China, mainly because of the large class sizes. This study redesigned CICO to facilitate its…

This study investigated whether the use of the color wheel system (CWS) during physical education (PE) classes is associated with a significant decrease in disruptive behaviors among middle school students. Using a multiple-baseline single-case design, we investigated the effects of the CWS on disruptive behavior in nine middle school students…

This study examined "backward transfer," which we define as how students' ways of reasoning about previously encountered concepts are modified when learning about new concepts. We examined the backward transfer produced when students learned about quadratic functions. We were specifically interested in how backward transfer may vary for…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

A growing body of literature supports the effectiveness of Modified Schema-Based Instruction (MSBI) to improve mathematical problem-solving for students with autism spectrum disorder (ASD) and intellectual disability (ID). MSBI is an intervention package that teaches students to identify the problem structure and use a problem-solving heuristic to…

The purpose of this study was to examine the effects of algebraic equation solving intervention for sixth graders with mathematics learning difficulties (MD). A total of 48 students with MD were randomly assigned to either the algebraic equation solving intervention, "Mystery Math" (n = 24) or control condition (n = 24). The…
