One of the crucial fundamental mathematical skills for students is mathematical communication. This skill pertains to students' ability to convey the ideas and information they have acquired effectively. However, many students still have suboptimal mastery of this skill. Therefore, this study aims to develop worksheets based on realistic…

Racially and ethnically diverse populations from minoritized backgrounds are often exposed to research methodologies that amplify structural racism and negate their sociocultural reality. Although cross-cultural validation of measures is considered a requisite step to multigroup comparisons, researchers apply measures validated and standardized in…

One of the most intransigent problems in mathematics education is the culturally-influenced divide between classroom practice and educational research. This paper describes our explicit attempt to bridge that divide by translating research on instructional practices linked to improving students' mathematics achievement into a brief guide outlining…

Research and design activities are often employed in STEM (Science, Technology, Engineering & Mathematics) education. This study aims to examine students' attitudes towards doing research and design activities in secondary school, among two groups of students: (1) students that take the quite recently introduced Dutch subject O&O (research…

This study aims to develop and examine a civic education textbook model based on living values education in order to foster the development of junior high school students' characters. This research employs Research and Development approach with an explorative method being used at model development stage and experiment method at model testing…

This design and development research was motivated by the rapid expansion and use of GeoGebra by mathematics educators (teachers and lecturers) in Indonesia. One of GeoGebra features is GeoGebra Applet that can be used, modified, and/or developed by educators for dynamic and interactive mathematics teaching and learning. At the time of research…

Prototype work can support the creation of data visualizations throughout the research and development process through paper prototypes with sketching, designed prototypes with graphic design tools, and functional prototypes to explore how the implementation will work. One challenging aspect of data visualization work is coordinating the expertise…

This study investigates the potential of a digital game that overlays popular game-play mechanics with formal physics representations and terminology to support explicit learning and exploration of Newtonian mechanics. The analysis compares test data, survey data, and observational data collected during implementations in Taiwan and the United…

Since 2003, the National Center for Education Statistics (NCES) has compared each state's standard for proficient performance in reading and mathematics by placing the state standards onto the NAEP scale. The procedure, "mapping," allows the level of achievement required for proficient performance in one state to be compared with the…

In 2001, the U.S. Department of Education and the Ministry of Education in China entered into a bilateral partnership to develop a technology-driven approach to foreign language learning that integrated gaming, immersion, voice recognition, problem-based learning tasks, and other features that made it a significant research and development pilot…

This two-volume monograph reports the results of the 24th national survey of drug use and related attitudes and beliefs among American high school seniors, the nineteenth such survey of American college students, and the eighth such survey of eighth- and tenth-grade students. The major purpose of this publication is to develop an accurate picture…
