Bullying victimization is a school problem that warrants attention. While most work has focused on understanding bullies and victims, it is important that research explore how to promote bystander behavior during bullying as a mechanism to deter bullying in schools. Perceptions of the school climate may impact the likelihood of a student's…

The jigsaw model is a dynamic cooperative learning approach where students become experts on different segments of the material and teach their peers, thereby enhancing engagement accountability, team work, and ultimately improving academic achievement. This study investigated the effectiveness of a cooperative learning strategy on secondary…

Partnerships between researchers and educators have become a common mode of working to support processes of school improvement. However, research on the processes and outcomes of long-term partnerships remains marginal. This paper increases our knowledge about the processes and experiences involved when researcher-interventionists introduce…

The creation and use of models in science is of great importance for knowledge production and communication. For example, toy models are often used as idealized explanatory models in physics education. Models can be a powerful tool for exploring phenomena in ways that facilitate learning. However, careful consideration of instruction and…

Keeping students in the classroom so that they are engaged with their teachers is a struggle. Students have many distractions in their lives other than school. When students are disruptive in the classroom the code of conduct or student handbook dictates the student's punishment. These are the zero-tolerance policies established in 1994 (Evans…

Intervention research often investigates the curriculum or methods used to support learners, while less attention is given to the model of those interventions. The purpose of this study was to evaluate the efficacy of two models of reading intervention, and to better understand how they are serving middle school students. Working from a critical…

Although cyber victimization has been suggested as a significant risk factor for the development of adolescents' depression, the underlying psychopathological process that mediates this relationship needs further exploration. Based on the psychological inflexibility model, this study aimed to examine cognitive fusion and experiential avoidance as…

This study analyzed the mediating role that implicit theories of intelligence and academic self-efficacy may play in the relationship between psychopathology and mathematical performance. The sample consisted of 838 students from first and second year of high school. A numerical calculation test was applied, followed by psychopathology self-report…

Understanding the impacts of professional development (PD) on teachers' perceptions of their knowledge, skills, and usefulness (KSU) of evidence-based practices is important, particularly for self-determination interventions in inclusive, secondary classrooms. Limited research exists examining the impacts of self-determination intervention PD on…

Computational modelling is widely used in biological science. Therefore, biology students need to learn computational modelling. However, there is a lack of evidence about how to teach computational modelling in biology and what the effects are on student learning. The purpose of this intervention-control study was to investigate how knowledge in…

The aim of this study is to investigate the types of teacher and peer interventions to test the validity of modelling along with the modelers' reactions to these interventions. A teaching experiment was employed in the study. Forty-five pre-service secondary school mathematics teachers participated in the research. As a data collection tool, a…

This cluster-randomised study investigated the effects of a Norwegian early warning system, the IKO model. IKO is a Norwegian acronym for identification, assessment, and follow-up, and the model aims to improve schools' abilities to identify and support students who are at risk of dropping out during the school year. The study involved 7677…

Noncompliance to treatment assignment is widespread in randomized trials and presents challenges in causal inference. In the presence of noncompliance, the most commonly estimated effect of treatment assignment, also known as the intent-to-treat (ITT) effect, is biased. Of interest in this setting is the complier average causal effect (CACE), the…

Background: To understand and apply the results of multisite impact studies, it is necessary to know the extent to which the components of an intervention were implemented as they were designed in each context (e.g., Carroll et al., 2007; Hill, Corey, & Jacob, 2018). Rigorous and cost-effective measures of implementation fidelity can help…

Research has indicated that by acquiring the skills realted to self-determination postschoool outcomes and quality of life are likely to improve for young adults with disabilities. Therefore, instructional efforts focused on fostering the self-determination skills is considered an essential component of the educational program and services for…
