Recent science education reforms highlight the importance for teachers to implement effective instructional practices that promote student learning of science and engineering content and their practices. Effective classroom discussion has been shown to support the learning of science, but work is needed to examine teachers' enactment of…

Adopting a sociocultural perspective, we construct a case study exploring how a middle school bilingual science teacher reflected and acted when engaged in dialogue, co-teaching, and a newly designed unit on plate tectonics. Sources of data include video of classroom interaction and audio recordings of daily debriefs between the bilingual science…

We have successfully developed a one-semester general chemistry course that meets the primary learning goals of the traditional two-semester sequence. It is appropriate for physical, life, and earth science majors. Since implementation, 88% of students who start general chemistry complete it, an increase from 72% in our prior traditional…

The COVID-19 outbreak has shut down universities and prompted the teaching faculty to move to online resources. In view of upcoming of new Medical Council of India (MCI) curriculum and outbreak of COVID-19 pandemic, keeping pace with medical education became a challenge. To keep on par with learning activities of undergraduate students during this…

The growing popularity of mobile technologies in educational settings, from grade schools through college, has prompted science educators to prepare preservice teachers to successfully integrate technology into science teaching. This mixed-methods study explores the effectiveness of a mobile technology-based physics curriculum, Exploring Physics,…

At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school-aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest…

In China, the latest version of the Senior High School Chemistry Curriculum (SHSCC) has been developed in response to social changes. This paper provides an account of the process and the product of the official document of this curriculum, "The Chemistry Curriculum Standards of Senior High School," with the purpose of exploring the way…

Scientific problems of the twenty-first century involve complex research questions that require an interdisciplinary approach. Educational research suggests that overall student achievement is greater in an interdisciplinary science curriculum than in a discipline-specific science curriculum. Regardless, the secondary school science curriculum in…

Understanding the nature and purpose of models, including mathematical models, is critical to enabling undergraduate chemistry students to use models to predict and explain phenomena. However, students often do not have systematic conceptions about different kinds of models. To gain a sense of how students understand different models in the…

This article presents findings from a multi-year study of a grant-funded professional development fellowship program that supports teachers in becoming science teacher leaders and improving science curriculum and instruction. The program's activities are designed to: (1) create and support a corps of teacher leaders, (2) institute a culture…

Following professional development (PD), implementation of contemporary topics into high school biology requires teachers to make critical decisions regarding integration of novel content into existing course scope and sequence. Often exciting topics, such as neuroscience, do not perfectly align with standards. Despite commitment to enacting what…

Recent reform efforts have been adopted in the United States to reimagine student learning in science. Historical reform efforts have required teacher buy-in necessary for substantive change to occur. Using a mixed-method methodology, chemistry teacher progress in implementing the "Next Generation Science Standards" in Illinois and views…

The science curriculum's potential for developing students' scientific literacy offers the ideal opportunity for addressing global concerns such as the 'post-truth' epidemic. In this article, we review the Year 10 "Australian Curriculum: Science" for its capacity to help students become producers and consumers of knowledge. We adopt a…

This study sought to assess the level of secondary students' scientific literacy in suburban schools in Malaysia and England, a research area which to date has not been fully explored in the literature. The study analyzed the data using the OECD's three domain-specific competencies of scientific literacy, namely: (i) explain phenomena…

This study evaluated the effectiveness of the Mathematics Infusion into Science Project (MiSP), which integrated science and mathematics in an engaging middle school science curriculum that fostered improvements in science content knowledge, higher-level problem solving, and affective domains related to mathematics. The project design was based…
