Purpose: The purpose of this study was to determine the 3-year trajectory of students' interest in learning physical activity (PA) knowledge during middle school and the effects of gender and prior knowledge on the trajectory. Methods: Using a repeated-measures design, a cohort of 447 sixth-grade students' interest in learning PA knowledge was…

Hierarchical linear modeling (HLM) has become an increasingly popular multilevel method of analyzing data among nested datasets, in particular, the effect of specialized academic programming within schools. The purpose of this methodological study is to demonstrate the use of HLM to determine the effectiveness of STEM programming in an Ohio middle…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on ELA achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) ELA assessment. This study compared the ELA achievement growth in the 2020-21 school year of students who…

Social schemas can influence the perception and recollection of others' behavior and may create biases in the reporting of social events. This study investigated young adolescents' (N = 317) gender-, ethnicity-, and popularity-based social schemas of overtly and relationally aggressive behavior. Results indicated that participants associated overt…

Advances in multilevel modeling techniques now make it possible to investigate the psychometric properties of instruments using clustered data. Factor models that overlook the clustering effect can lead to underestimated standard errors, incorrect parameter estimates, and model fit indices. In addition, factor structures may differ depending on…

Student reports are a common approach to characterizing how students experience their classrooms. We used a recently developed method--multilevel confirmatory factor analysis--to determine whether commonly employed measures of achievement goal structure constructs (mastery and performance) typically verified at the student level can be verified at…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

This research examined how children's inclusion of social personal attributes (e.g., talkative and argumentative) in their views of themselves changes over early adolescence in the United States and China. In 2 studies (N = 825 in Study 1 and 394 in Study 2) using open-ended methods (e.g., completion of "I ... " stems), American and…

This study aimed to investigate the factors accounting for science learning self-efficacy (the specific beliefs that people have in their ability to complete tasks in science learning) from both the teacher and the student levels. We thus propose a multilevel model to delineate its relationships with teacher and student science hardiness (i.e.,…

This study tested the theory that an authoritative school climate characterized by disciplinary structure and student support is conducive to positive academic outcomes for middle and high school students. Multilevel multivariate modeling at student and school levels was conducted using school surveys completed by statewide samples of 39,364…

Based on analyses of 1,622 Hmong adolescents in a large urban school district, we illuminate a positive association between school different-race exposure and Hmong limited English proficient students' reading achievement. However, we also note a negative association of neighborhood different-race exposure with Hmong students from low…

This study examined the role that everyday academic successes and failures--and the interactions with family members and peers that follow these events--play in predicting day-to-day changes in children's emotional responses to school. Middle school students (N = 101; mean age = 11.62 years) completed daily assessments of their academic…

This study investigated bullying victims' perceptions of their teachers' support and monitoring when controlling for level of mental health problems, peer relationships, gender, and grade level. Given the nested structure of the data, multilevel analyses were employed to examine these associations. The quality of classroom interaction is highly…

Teachers make a difference for the outcome of their students in science classrooms. One focus in this context lies on teachers' professional knowledge. We describe this knowledge according to three domains, namely (1) content knowledge (CK), (2) pedagogical content knowledge (PCK), and (3) curricular knowledge (CuK). We hypothesise a positive…

Reading instruction often does not focus on appealing to student interests, offering choice, or responding to the needs of advanced readers. In this experimental study, we examined the effects on achievement of an instructional approach involving choice, differentiated instruction, and extensive, supported, independent reading, with corresponding…
