The purpose of this longitudinal study was to explore the development of pre-service chemistry teachers' pedagogical content knowledge regarding the effect of temperature on reaction rate topic as they took pedagogical content knowledge courses throughout the teacher education program. Pre-service teachers' pedagogical content knowledge was…

This article critically explores the epistemic "practices" of bioscience, using creative writing and analyses of science studies to implicate the non-linguistic side of science where a "feeling for the organism" matters more, perhaps, than theoretical precision. It offers new critique of curricula in science which are so…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

When conducting biological investigations, experts constantly integrate their conceptual and quantitative understanding of variation with the design and analysis of the investigation. This process is difficult for students, because curricula often treat these concepts as separate components. This study describes the effect of a curricular…

Recent educational policies advocate a radical revision of science curricula and pedagogy, to support interdisciplinary practices, a distinguishing feature of contemporary science. Computational modeling (CM) is a core methodology of interdisciplinary science, as such models allow intertwining of data and theoretical perspectives from multiple…

Understanding scientific models and practicing scientific modeling have been emphasized and advocated in science learning. Although teachers have been perceived as shaping their students' understanding of the nature of science, they have been recognized for their lack of understanding of scientific models. This study explores middle school science…

"Kurikulum Merdeka" is a learning experience framework that offers flexibility and focuses on essential content, character development, and students' competencies. Teachers had the discretion to develop their modules to choose, design, and organize the learning contents for students, based on their needs. By using that module, there is…

America's most popular science curriculum, the Next Generation Science Standards (NGSS), fails students. This report details how the popular curriculum omits basic tenets of science, including the scientific method, and provides recommendations to correct deficiencies in the NGSS.

Recent science education reform initiatives suggest that learning in science should be organized on the basis of scientists' actual practices including the development and use of models. In line with this, the current study adapted three types of modeling practices to teach two Korean 6th grade science classes the causes of the Earth's seasons.…

The inclusion of engineering in the Next Generation Science Standards (NGSS) as a key component of K-12 science learning has provided both opportunities and challenges for elementary teachers. One challenge is integrating the design thinking processes that undergird engineering with core science concepts and current issues facing scientists and…

This study studied the types of peer scaffolding presented in scientific experimental activities. The study included 14 university students. For the experimental activity of 'determining temperature changes using the meridian altitude of the sun,' information regarding experimental behaviors, thinking aloud, discourse, and retrospective interview…

Providing opportunities for science, technology, engineering, and mathematics undergraduates to engage in authentic scientific practices is likely to influence their view of science and may impact their decision to persist through graduation. Laboratory courses provide a natural place to introduce students to scientific practices, but existing…

Learning about heredity is important across the K-12 continuum. However, these ideas may be challenging for students. We examined third-grade students' ideas about heredity in the context of a new, six-week, model-based science unit that uses corn as a model organism to support students' ideas about heredity. We analyzed data collected during…

The shift from science inquiry to science practices as recommended in the US reports "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" and the "Next Generation Science Standards" has implications for classroom/school level instruction and assessment practices and, therefore, for…

This article describes an instructional model for integrating children's literature and language arts into the elementary school science curriculum. This science-literacy instructional model is an adaptation from the original 5E model of scientific inquiry. The model demonstrates how reading, writing, listening, and speaking can be incorporated…
