The goal of the study was to compare how visual representations were integrated into the contents of the U.S. and Turkish textbooks used in life science. Data was collected from 6th, 7th, and 8th grade middle school topics common to both countries. Content analysis was used to analyse visual representations in textbooks. The visual representations…

The Precipitating Change Project was a 5-year development, implementation, and research study of an innovative 4-week middle school curricular unit in computational weather forecasting that integrates students' learning and use of meteorology and computational thinking (CT) concepts and practices. The project produced a list of CT skills and…

This study examines the direct and indirect relationships between key motivational constructs and science achievement using TIMSS 2019 data sets for Japan, Norway, and the United States. The sample of the study includes 4,446 and 8,698 eighth graders in Japan and the United States, with 4,575 ninth graders in Norway. The structural equation model…

The authors present evidence-based digital literacy practices and resources for teaching and learning English as an additional language in two different educational contexts where these practices have been applied successfully with adolescent learners.

In peer nomination research, individuals who do not provide nominations (nonparticipants) are often included on rosters as potential nominees. This can present ethical questions regarding informed consent, but psychometric consequences of excluding nonparticipants from rosters are unknown. In this investigation, Study 1 simulated both random and…

There are substantial differences between the Chinese and US education systems. One difference is in the design and use of assessment due to differences in educational policies. This study described the differences in student learning outcomes, instructional approaches, and learner motivation in physical education as consequences of the policies…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

Purpose: The digital age has provided new possibilities for the connected learning. To better understand these opportunities in the school context, the purpose of this paper is to examine what kinds of learning communities emerge in international learning projects and how tools and technologies support students' inquiries and peer connections.…

Science, technology, engineering, and mathematics (STEM) education is an international focus in teaching and learning, and factors influencing students' science achievement vary throughout the world. Guided by the Social Role and Expectancy-Value Theories, we investigated the role of fourth and eighth graders' gender and attitudes toward science…

This study analyzed geometry problems in four middle-grade mathematics textbook series from Taiwan, Singapore, Finland, and the United States, while exploring the expectations for students' learning experiences with these problems. An analytical framework developed for mathematics textbook problem analysis had three dimensions: representation…

We report here on a comparative study of middle school students' attitudes towards science involving three countries: England, Singapore and the U.S.A. Complete attitudinal data sets from TIMSS (Trends in International Mathematics and Science Study) 2011 were used, thus giving a very large sample size (N = 20,246), compared to other studies in the…

There has been a recent call to improve data reporting in kinesiology journals, including the appropriate use of univariate and multivariate analysis techniques. For example, a multivariate analysis of variance (MANOVA) with univariate post hocs and a Bonferroni correction is frequently used to investigate group differences on multiple dependent…

How do teachers help students realize their place in the universe? How do they teach the relationship among the Earth, Moon, stars, and galaxies during daylight hours? Most teachers assume that astronomy is a difficult subject to teach in the classroom and that without a planetarium little can be learned. In this article, the authors discuss…

The purpose of this study is to investigate the implementation of a whole school one-to-one iPod Touch project in a middle school in the southeastern United States. While some focused studies have been undertaken in this new field of learning, there has been little research to date that documents activity within a whole school implementation…

Most existing research indicates that working students perform more poorly than do full-time students on standardized achievement tests. However, we know there are wide international variations in this gap. This article shows that national and international contexts help to explain the gap in the academic performance between working and nonworking…
