Astronomy education is essential for STEM education in primary schools, and integrating engineering design-based science education enhances student engagement and achievement in the field of space science. Integrating engineering design into science education is essential for students to excel in astronomy and to meet the requirements of…

Reconceptualized Family Resemblance Approach to Nature of Science (RFN) explains science as a cognitive, epistemic, and social institutional system. The aim of this study is to examine the inclusion of Nature of Science (NOS) in the 5th, 6th, 7th, and 8th grade Turkish middle school science textbooks. The "content," "activity,"…

Science, Technology, Engineering, and Math (STEM) have developed broad prevalence in the American (U.S.) education system over the last decade. Academic, government, and business experts emphasize that attracting K-12-university students to STEM subject matter is crucial for expanding the innovation capacity of the U.S. and preparing citizens for…

"A Framework for K-12 Science Education" (NRC 2012) recommends that science teachers provide experiences for students to see "how science and engineering pertain to real-world problems and to explore opportunities to apply their scientific knowledge to engineering design problems once this linkage is made" (NRC 2012, p. 32). To…

Genetics is the cornerstone of modern biology and a critical aspect of scientific literacy. Research has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed decisions about issues and emerging technologies in this domain, such as genetic screening, genetically modified foods, etc.…

This article reports findings from a study examining how altered readability levels affected struggling readers' (N = 288) comprehension of scientific concepts and vocabulary. Specifically, the researchers were interested in learning what effect altered readability levels have when low ability readers participate in a technology-based science…

Explains the story of four sixth-grade students, of mixed race and social class, who worked together in a small group experimenting with colored solutions with different densities. Describes students' failures in achieving intersubjective communication using the sociolinguistic concepts of polysemy and privileging. (Contains 41 references.)…

In this study, a conceptual change model serves as a theoretical underpinning for analyzing what might count as evidence of conceptual change. Theoretical components of the conceptual change model include the status a conception has for learners, and the conceptual ecology of knowledge within which conceptions are believed to survive and have…

Describes science activities for a field trip to the beach for sixth-grade students. Explains how students can save what they find using plaster of Paris to create a sand cast. (PR)

Describes instruction in an urban sixth-grade classroom in which students are learning about mass, volume, and density by attempting to layer three miscible solutions of differing densities atop one another. Contains 24 references. (DDR)

The purpose of this study involving 12 classrooms was twofold: (1) to understand the conceptual frameworks that sixth-grade students use to explain the nature of matter and molecules, and (2) to assess the effectiveness of 2 alternative curriculum units in promoting students' scientific understanding. Results reveal that students' entering…

Describes an instructional program designed to promote scientific literacy among middle grade students. The program used a collaborative group instruction approach and focused on the development of tasks that provided students with opportunities to solve problems and to employ concepts useful to scientific problem solving. (PAM)

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

This study investigates the fate of claims made by middle school science students working in collaborative groups in a multicultural urban classroom and the concomitant effects on engagement and understanding. Given problems of a complex and open-ended nature in a learning community setting, students were challenged to establish group positions…

These item specifications were developed as a part of the Arkansas "Minimum Performance Testing Program" (MPT). There is one item specification for each instructional objective included in the MPT. The purpose of an item specification is to provide an overview of the general content and format of test items used to measure an…
