In this study we introduce an infusion model to "inject" ammonites and ammonite fossils in current subjects of Greek primary curriculum. Paleontology and mainly fossils attract more and more elementary students and teachers, yet in Greece this trend is solely about dinosaurs, despite the fact that the most common Greek fossils are not…

This article aims to investigate how science teachers engaged with the macroscopic, sub-microscopic and symbolic levels of representations in their Chemistry teaching. Data were collected in Limpopo province in South Africa from 15 "lead" teachers and this paper reports on five lessons presented by the teachers during professional…

In their classrooms, the authors observed students experiencing meaningful and memorable learning when they were immersed in scientific inquiry involving Bess beetles. Students who learn from active, experiential instruction, find such learning to be exciting and emotionally engaging. As a result, they learn more deeply and effectively. This…

During the second industrial revolution (1870-1914), scientists moved away from trial-anderror methods to more systematically apply the principles of chemistry, physics, and biology (Mokyr 1998). The authors chose this period as the foundation of a project-based learning (PBL) unit integrated with the ninth-grade U.S. history curriculum (Thomas…

Depending upon a cultural-historical perspective, where play is defined as the creation of an imaginary situation, this study seeks to examine whether and how family joint creation of imaginary situations can provide the conditions for a child's science learning in early childhood. The paper reported here forms part of a broader study, and the…

This report describes efforts by a group of science teachers, teacher educators, researchers, and content specialists to conceptualize, develop, and pilot practice-based assessment items designed to measure elementary science teachers' content knowledge for teaching (CKT). The report documents the framework used to specify the content-specific…

This article focuses on an argument-based inquiry (ABI) approach to a fourth grade unit on waves. A fourth-grade teacher included multiple opportunities for students to read, write, and use language to represent their understanding of physical science Next Generation Science Standards (NGSS) performance expectations (NGSS Lead States 2013). He…

Avogadro's conception of the structure of gases was not widely accepted by his contemporaries--probably because the hypothesis was not supported by direct evidence. This problem is rarely addressed in schools. This article discusses the difficulties that accompany the acceptance of new ideas. Such difficulties may be associated with the ways in…

The purpose of the study was to explore Turkish primary science teacher candidates' understanding of global warming and ozone layer depletion. In the study, as the research approach the survey method was used. The sample consisted of one hundred eighty nine third grade science teacher candidates. Data was collected using the tool developed by the…

Concept maps measured a student's understanding of the complexity of concepts, and interrelationships. Novak and Gowin (1984) claimed that the continuous use of concept maps increased the complexity and interconnectedness of students' understanding of relationships between concepts in a particular science domain. This study has two purposes; the…

Recent educational legislative acts and public debates in Sweden stress the importance of preschools providing playful and meaningful activities to enhance early experiences in environmental and natural science (e.g., Ministry of Education and Research, 2016). The present study investigates three 5-6 year old children making meaning of the concept…

The central dogma has served as a foundational model for information flow, exchange, and storage in the biological sciences for several decades. Despite its continued importance, however, recent research suggests that novices in the domain possess several misconceptions regarding the aforementioned processes, including those pertaining…

Undergraduate biology education reform aims to engage students in scientific practices such as experimental design, experimentation, and data analysis and communication. Graphs are ubiquitous in the biological sciences, and creating effective graphical representations involves quantitative and disciplinary concepts and skills. Past studies…

In this paper, we present a study of second graders' learning about the nature of matter in the context of content-rich, model-based inquiry instruction. The goal of instruction was to help students learn to use simple particle models to explain states of matter and phase changes. We examined changes in students' ideas about matter, the coherence…

Doing science involves the development and evaluation of models. These models are not objective truths but can be understood as explanations, which scientists use to explore and reason about an aspect of the world. Learning science involves students expressing and engaging with models in the classroom. However, this learning should not be seen as…
