Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking.…

Background: In recent years, data derived from international large-scale assessments have significantly influenced the discourse surrounding educational equity. However, the use of such data has often neglected the full spectrum of dimensions that equity encompasses, while being limited to exploring the relationship between achievement variations…

THS is applied to Science High Schools, Social Sciences High Schools, Anatolian Technical Programs of Vocational and Technical Anatolian High Schools and Project schools for student selection. With THS, approximately 10 percent of more than one million students are placed in a secondary education institution based on their preferences. The purpose…

Background: To inform STEM education for benefiting emerging bilingual (EB) and English fluent (EF) students, the present study evaluated the order effects of integrating science and arts within a large-scale, ongoing effort investigating the efficacies of Next Generation Science Standards (NGSS)-aligned Science Technology, Engineering, and Math…

Science classroom assessment often requires multilingual learners to demonstrate ideas using only English-language resources. These assessments can provide an incomplete picture of students' knowledge and limit subsequent learning opportunities. Increasingly, science teachers are incorporating translanguaging pedagogies in their instructional…

Students living in poverty tend to perform worse in school than their peers from better-off families. This paper examines whether computer availability helps narrow down educational inequalities in Slovakia, using TIMSS and PIRLS data. The results show that computer availability in reading lessons improves reading scores and that the effect is…

Background: Socioeconomic characteristics are persistently and systematically related to academic outcomes, despite long-standing efforts to reduce educational inequality. Ireland has a strong policy focus on alleviating educational disadvantage and has seen significant improvements in mathematics and science performance in recent years. This…

This brief examines Trends in International Mathematics and Science Study (TIMSS) science achievement of the 20% highest and the 20% lowest performing fourth and eighth graders in 11 countries. To do so, the authors compare achievement distributions across countries, using measures of relative equality within countries. Such an examination…

Since the early 1980's, a push for equitable learning practices has resulted in the creation of culturally centered pedagogy to counter educational disparities targeting marginalized populations across disciplines--particularly within the Black/African American community. More recently, scholarship centering on race in science education, language…

More attention should be placed on student engagement and the teaching of lessons that promote equitable opportunities to learn science in a way that students can relate to and enjoy. The purpose of this action research study was to investigate and improve student engagement in urban elementary science classrooms. Also, to discover how best to…

Relative to their middle and high school teacher counterparts, elementary science teachers are both uniquely situated and uniquely challenged for excellent science instruction. More than 90 percent of elementary teachers work in self-contained classrooms, meaning they have opportunities to connect their science instruction with English language…

The adoption of "A Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS) across the U.S. requires that the field of science education develops high-quality instructional materials. This need is particularly urgent as schools and districts are expected to design or adapt instructional materials for an…

Research to date on the effects of between-school tracking on inequalities in achievement and on performance has been inconclusive. A possible explanation is that different studies used different data, focused on different domains, and employed different measures of inequality. To address this issue, we used all accumulated data collected in the…

As historically construed, both engineering culture and school science culture marginalize girls. With the focus on engineering in the Next Generation Science Standards (NGSS), engineering education researchers have called for a more targeted investigation of how girls at the K-12 level engage in engineering. This study investigates, through…

Over the course of six years, a diverse group of school districts and charter management organizations in California ran a substantial experiment in implementing the Next Generation Science Standards (NGSS) in elementary and middle grades. WestEd led an extensive evaluation of that effort, the California K-8 NGSS Early Implementers Initiative,…
