The purpose of this research was to examine the effects of Inquiry-Based Learning (IBL) on the academic achievement, attitudes, and engagement of fifth-grade science students. Participants were from two science classes (N = 42). The experimental group received IBL instruction, while the control group received traditional instruction. Pretests and…

Everyone enjoys seeing the cloudy white fog generated when solid carbon dioxide (dry ice) is placed in water. Have you ever wondered what physical and chemical processes occur to produce this fog? When asked this question, many chemical educators suggest that the fog is produced when atmospheric water vapor condenses on cold carbon dioxide gas…

Career and educational opportunities in food science and food safety are underrecognized by K-12 students and educators. Additionally, misperceptions regarding nature of science understanding persist in K-12 students despite being emphasized as an important component of science education for over 100 y. In an effort to increase awareness…

Despite the abundance of research in Modeling-based Learning (MbL) in science education, to date there is only limited research on MbL practices among K-6 novice modelers. More specifically, there is no information on how young/novice modelers' modeling enactments look so that researchers and educators have an idea of what should be expected from…

Although classroom inquiry is the primary pedagogy of science education, it has often been difficult to implement within conventional classroom cultures. This study turned to the alternatively structured Montessori learning environment to better understand the ways in which it fosters the essential elements of classroom inquiry, as defined by…

This article describes how observing whether objects sink or float in water using the P-E-O (Predict, Explain, and Observe) technique is an elementary precursor to developing explanations in later grades that involve an understanding of density and buoyancy. Beginning as early as preschool, elementary students engage in activities that encourage…

Since the 1970s, a small but committed group of educators and developers has been encouraging students to learn the language of technology: computer programming. This article describes how today those efforts are moving forward, as a number of kid-friendly languages are being developed with the goal of harnessing students' attention and…

Despite the pressures on education and educators today -- seemingly from all sides -- science teachers provide critically important opportunities for students to develop the scientific knowledge and skills they will need as adults. This preparation empowers them to make well-informed decisions as citizens, as well as to use this knowledge as a…

Earth's surface is constantly changing. Weathering, erosion, and deposition break down Earth materials, transport those materials, and place them in new locations. Children see evidence of these processes all around them. The sidewalk or playground surface cracks and has plants growing in it. Pieces of a rock wall or the sides of a building…

How the heart works is found in "A Framework for K-12 Science Education" and connects to Life Sciences Core and Component Ideas, From Molecules to Organisms: Structures and Processes (NRC 2012). By the end of grade 2, students should understand that all organisms have external parts, which they use in various ways to seek, find, and take…

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa's 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers…

In this article, Clare Rees describes the interest of staff and children alike when their school added the newest and possibly coolest iPad "tablet computers" to the classroom. Everyone wanted to get their hands on them. But how were they going to use them as teaching and learning tools? How were they actually to be used in the…

Recent comparative data on high school graduates show that many American students are not well prepared in fields of science, technology, engineering, and mathematics and that there is a persistent achievement gap according to the socioeconomic backgrounds of students. The research for this paper focuses on the role of elementary education in…

This ethnographic research examines how children enact developing understandings in science through multiple interactions. Grounded in sociocultural theoretical frameworks, we consider learning to be a social, cultural practice, with understandings as co-constructed between participants through talk and in interactions. With these underpinning…

We present a collection of analogies that are intended to help students better understand the foreign and often nuanced vocabulary of the genetics curriculum. Why is it called the "wild type"? What is the difference between a locus, a gene, and an allele? What is the functional (versus a rule-based) distinction between dominant and…
