A service-learning model was used in a science methods course for elementary teachers as the context for integrating key pedagogical strategies necessary to attain current national and state standards. This innovation provided a real-world problem-solving experience and introduced learners to service-learning through personally relevant…

Web-based multimedia annotation is a valuable tool for engaging learners with diverse materials. This study aimed to assess the effects of multimedia annotation on student performance, self-regulation, and cognitive load in an online learning environment. We developed and implemented a multimedia annotation system in an online biology class using…

Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

This study examines Chinese primary science teachers' professional learning experience in a web-based community of practice established and run by practitioners, with support from teacher researchers. Over time, it has grown into a preferred knowledge-sharing base for primary science teachers of the region and gradually gained national…

This article reports on a controlled study to investigate the efficacy of incorporating explicit discussions about the duality of human reasoning and its implications for learning in physics instruction. The central goal is to probe to what extent, if at all, such discussions improve student performance on tasks that tend to elicit intuitively…

Reform documents advocate for innovative pedagogical strategies to enhance student learning. A key innovation is the integration of science and engineering practices through engineering design (ED)-based physics laboratory tasks, where students tackle engineering design problems by applying physics principles. While this approach has its benefits,…

In this study, we investigated the relationships between three pivotal factors that influence student performance, including opportunity-to-learn (OTL) factors, which included proximal indicators that represent science-specific learning opportunities, student motivation (propensity factor), and crucial student and teacher antecedent factors by…

Digital learning environments such as virtual laboratories have been proposed to augment or even replace conventional forms of teaching in recent years. While there is some evidence on comparable learning outcomes between real and virtual labs, empirical evidence on the effectiveness of virtual labs as compared to conventional face-to-face…

Epigenetics shows how environmental factors and life experiences alter gene activity without changing the gene sequences. This review examines key epigenetic mechanisms such as DNA methylation, histone modifications, microRNAs, and long non-coding RNAs, and their roles in gene regulation. It also highlights the impact of maternal diet, stress, and…

This research will analyze the issues encountered by two science teachers implementing Arduino-based robotic coding projects. This research employed a case study design. This research has used a criterion sampling group. This study used semi-structured observation, interviews, and video observations as data collection tools. The teachers conducted…

Plate tectonics is the unifying theory of modern Earth science, but many university students have misconceptions about it that introductory geoscience classes often fail to correct. We developed a 5-to-12-hour-long hands-on active-learning curriculum for an introductory geoscience class for education majors. The curriculum includes: (1) A…

In this paper, we describe the development and preliminary assessment of ACORN Physics Tutorials, which are designed to elicit and build on common conceptual resources for understanding physics. We articulate our design principles and instructional commitments and how these bear out in the specifics of one ACORN Physics Tutorial about electric…

One type of active learning technique that instructors can incorporate is the use of various drawing activities. This study investigates the impact of drawing during biology lecture classes on student learning. Undergraduate students in two lecture sections of an introductory cellular and molecular biology course completed worksheets that either…

The provision of quality science education in basic schools in Ghana remains a significant challenge, particularly in resource-constrained settings such as the rural basic schools of the nation. This study explored the lived experiences of Integrated Science teachers in these rural schools, specifically in the Gomoa East District (GED), focusing…

This study, titled Exploring the Determinants of Primary School Students' Attitudes Toward Science: Insights from Students, Teachers, and Head Teachers in the Left Bank 2B District of Liberia, investigates the factors that shape learners' attitudes toward science. Drawing on theoretical and empirical foundations, this study explores how…
