The effectiveness of class size reduction on student performance has been of great research interest and policy debate worldwide. Nevertheless, the evidence has been largely inconclusive partially due to potential bias arising from non-random placement of students and teachers in classrooms of different sizes. This study applied instrumental…

Different approaches are employed when teaching environmental issues. One approach, termed the "environmental scientific approach," perceives environmental education as part of life or earth sciences, providing factual, scientific knowledge. Another approach, termed the "environmental sustainability citizenry approach",…

This descriptive case study aimed to understand the perception and needs of Michigan public high school science teachers during the implementation of the Next Generation Science Standards (NGSS) and subsequent preparedness to teach the content found in the new curriculum. A questionnaire was distributed to science teachers state-wide, with twenty…

Through teaching science, teachers have the pleasure of developing and implementing learning experiences that allow students to discover how the world works. Interweaving the laws, principles, and theories of the universe with scientific practices that have allowed scientists to discover these ideas is the focus of teaching and learning in the…

This article describes a project that integrates English Language Arts (ELA) and coding into environmental science. For this project, students researched science content about human impact on the environment, communicated their findings through a traditionally formatted narrative story, and then used a coding program called Scratch to create an…

Student mastery of the academic vocabulary of course content is an important component of learning that content. This research study investigated the combination of two active multimedia strategies within 10 different high school science classrooms, to test for retention of science terminology. The dual process of learner-generated drawings…

Chapter 1 is a seismic study of the mantle structure of the passive margin of northeastern North America. This region experienced multiple episodes of rifting and orogenesis in the past, and the study aims to understand how the Wilson Cycle impacts the geometry of the upper mantle seismic structure beneath southern New England using Sp receiver…

Students who enter introductory geology classes often have misconceptions about geoscience research, and they seldom have opportunities to gain authentic research experience in these classes. To improve student engagement in the class and understanding of geoscience research methods, a semester-long authentic inquiry research project was…

As science textbooks are considered as one of the major source of climate change information of students, this study aims to examine the differences in energy saving and carbon reduction knowledge, attitude, and behavior between two groups of Taiwan's high school students using earth science textbooks of two different publishers. Some items of…

Driven by our technologically advanced workplaces and the surge in demand for proficiency in the computing disciplines, it is becoming imperative to provide computational thinking (CT) opportunities to all students. One approach for making computing accessible and relevant to learning and problem-solving in K-12 environments is to integrate it…

Burlington Junior School in the East Riding of Yorkshire decided to highlight some excellent role models to its pupils during British Science Week 2021, who were not the stereotypical male, white, old or dead scientist. The intention was to make learning more relevant, more accessible and therefore more engaging and informative. It was hoped that…

A novel learning intervention has been developed and tested in which honor's level Earth science students were tasked with conducting interviews with established geologists working in the Southern African minerals sector. The task was designed using Laurillard's conversational framework as a theoretical underpinning, which offers an iterative and…

Today, individuals need a solid understanding of how earth as a system works in order to understand and develop solutions for science-based issues affecting societies on a global scale such as natural disasters, global warming or COVID-19 pandemic. Humans also deliberate space investigations, such as interplanetary travels and life in space.…

Recent science-education reforms have targeted students' ability to 'talk science', especially in science classrooms. Prior research has shown that participation in scientific discourse in class is one of the most challenging scientific-literacy tasks, and particularly complex for English language learners (ELLs) at the upper elementary level. The…

Self-efficacy plays a key role in determining teaching practices. Still, concerns regarding the low science self-efficacy beliefs held by elementary teachers have raised questions about the effectiveness of teacher preparation programs. Previous research has been restricted to labeling preservice elementary teachers as having high, medium, or low…
