The leading cause of preventable disease, disability, and death in the United States is tobacco product use. The 2022 National Youth Tobacco Survey, which was completed in 2022, showed that the e-cigarette epidemic among youth continues to remain a public health threat. The survey revealed that over 2.5 million middle and high school students…

In the present study, we illuminate students' multiplicative reasoning in the context of their units-coordinating activity. Of particular interest is to investigate students' use of three levels of units as given material for problem-solving activity, which we regard as supporting a more advanced level of multiplicative reasoning. Among 13 middle…

We examined the effects of a text-based argument writing intervention, "Triple Q," on argument writing skills in a cluster-randomized trial where groups of middle schools were assigned to conditions within school-level SES blocks. The intervention comprised three 15-day units. Students read and discussed argument texts representing…

Background: While vaccines have reduced the incidence of vaccine-preventable diseases, vaccine hesitancy threatens the re-emergence of childhood infectious diseases. Purpose: This randomized controlled study evaluated an online vaccine education program to advance vaccine acceptance among middle-school students. Methodology: Study participants…

This study explored four middle-school mathematics teachers' provision of non-examples and instructional explanations in teaching rational numbers to seventh-grade students. The data sources were 8 lesson hours of observations conducted in four different classrooms. Yin's [(2018). "Case study research and applications: Design and…

In this study, it was aimed to develop a rubric to evaluate the creative story writing skill levels of seventh grade secondary school students. The research was designed in quantitative research method and survey model. In the research, convenience sampling technique was used and 270 students studying at the seventh grade level of secondary school…

The current study examined whether bystander behaviours in class were associated with being perpetrators of ethnic victimization and whether they moderated the association between disengagement from morality and perpetrating ethnic-based victimization. The sample included 1065 adolescents residing in Sweden (M[subscript age] = 13.12, SD=.42; 55%…

The aim of this study is to develop a theoretically sound, valid, and reliable scale to examine seventh and eighth grade students' attitudes towards so-called skill-based mathematics questions (SBMQ). The sample of the study was 820 seventh and eighth grade students at three different middle schools in Etimesgut District of Ankara Province. A…

The focus of this study is to investigate the effects of using Web 2.0 tools in the social studies "Global Connections" learning area on students' digital literacy levels.

In this article, the author argues that living literacies--relational, embodied forms of literacy engagement--are an integral component of literacy engagement and hold the potential to disrupt and reconfigure the power structures embedded within schooled literacy. Drawing on affect theory and rhizomatic theory, the author analyzes youths' literacy…

The study advances the instrumental approach to mathematics education (Drijvers et al., 2013; Trouche, 2003), aiming to elucidate the interplay between students' reasoning competency, conceptual knowledge and tool utilisation in dynamic digital geometry and algebra environments. The dynamic properties of these environments pose a nuanced…

This study aims to investigate students' computational thinking (CT) through mathematical tasks integrated with programming in Scratch. Participants completed four tasks that required students to solve coding problems, which were focused on prime numbers and the prime factorization algorithm. The study was designed as a case study and the unit of…

This study aimed to explore the design and development of verbal prompts in virtual reality (VR)-based social skills training for autistic children. Autism indicates a category with neurodiversity that influences individuals' capability to engage in social and cognitive tasks.
