Background: In the previous decades many research papers and educational documents have emphasized the importance of the application of history of science in the science education of students. Consequently, chemistry teachers are expected to be familiar with the historical development of science and capable of incorporating historical contents in…

Understanding and supporting students' development of graph literacy is important. We studied how aspects of graph literacy might be supported (or hindered) in middle school by analyzing the content in textbooks. Specifically, we conducted a content analysis of tasks involving two-dimensional Cartesian graphs presented in grade 6-8 US textbooks.…

Computational thinking and programming have emerged as central 21st-century skills. Several countries have embedded these skills in their school curricula. This study investigates how an optional programming course affects eighth-grade mathematical problem solving in Norway using a quasi-experimental design with pre- and post-tests. These tests…

This study explored the interest, outcome expectations, choice goals and choice actions in engineering and technology, collaboration value, problem solving attitudes, and spatial reasoning and orientation skills of 63 middle school females in grades six, seven, and eight. The participants were involved in a five full-day coding robotics summer…

This study diagnoses and explores year eight students' misconceptions and mistakes in algebra. An in-depth exploration of students' misconceptions were carried out by conducting interviews based on the students' work as outlined in a cognitive map. Based on the cognitive maps, it can be seen that the students emphasize procedural knowledge rather…

This study employed a word association test to determine middle school students' cognitive perceptions and misconceptions of the key concepts regarding "cycles of matter and environmental problems." The study adopted descriptive research in survey model. The sample consisted of 457 eighth-grade students from four middle schools…

A group of adults, dressed in authentic medieval costumes, organize and stage a full-scale battle at a local park; weapons (made from foam), roles, and medieval speech are all part of the event. This is known as "Live Action Role Play" -- more commonly referred to as "LARP." Although many settings and scenarios have been used…

In this paper, we discuss the design and development of an eBook titled "Building Democracy for All: Interactive Explorations of Government and Civic Life," which serves as an open educational resource for the eighth-grade Massachusetts social studies curriculum standards. This design case offers an example of an interactive,…

Background: There is extremely limited population-based research on social (pragmatic) communication disorder (SCD). Population-based samples have the potential to better characterize the SCD phenotype by mitigating confounds and biases that are typical of convenience and clinical samples. Aims: The aims of this preliminary epidemiologic study…

Communication is the result of meaning making based on one's frames of knowing. For students, those frames of knowing derive heavily from multimedia communication, including social networking sites, that allow them to be the makers of content. In this study, I followed an eighth-grade student who fluidly negotiated a multitude of available social…

The achievement gap has alluded school leaders for more than 50 years. Students living in poverty are continually at the bottom of every academic measure, specifically in mathematics. The COVID-19 closures have exacerbated the gap to a point where it will be noticeable for our entire lifetime. This study sought to enlighten educators on the…

The share of students attending charter schools has been rising. There is evidence that charter school growth has increased socioeconomic segregation of students between schools. In this paper, we assess whether charter school growth affects how students are organized within nearby traditional public schools (TPS). We use administrative data from…

Machine learning (ML) methods for causal inference have gained popularity due to their flexibility to predict the outcome model and the propensity score. In this article, we provide a within-group approach for ML-based causal inference methods in order to robustly estimate average treatment effects in multilevel studies when there is cluster-level…

This article focuses on the role of language ideology in four students' ethnic identity during one stage. I employ Bakhtin's concepts of ideological becoming, and of authoritative and internally persuasive discourse to explore how the student participants are conscious of language and social worlds, including their heritage language and ethnic…

Grade retention is one of the most discussed and controversial educational measures, and yet, it is still widely applied in many countries. Research investigating the effects of grade retention on students' psychosocial variables presents mixed findings, partly due to the variables assessed, methodological issues, and the length of the studies.…
