This study aims to develop and evaluate an augmented reality microscope, "MicrosAR", for a middle school Science course, which was aimed for use both in and out of school, and to understand the users' perceptions about it. The study adopted design-based research to iteratively develop and evaluate the MicrosAR. Learning activities and…

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 textbooks play an important role in making scientific knowledge and applications available to learners. In most countries, science curriculum expects to cultivate scientifically literate individuals who are able to use science process skills. Critical analysis of textbooks is therefore crucial to determine whether they can facilitate this…

In this article the authors describe an Integrative Science Technology Engineering and Mathematics (STEM) Education Design-Based Learning (I-STEM ED DBL) activity that invites students to delve into the science, technology, and engineering related to the production of Ötzi's copper axe and to speculate about the circumstances surrounding his…

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical…

This study explores upper-elementary and early-middle-school students' ideas about cells and inheritance and describes patterns of understanding for these topics. Data came from students' responses to embedded assessments included in a technology-enhanced curriculum designed to help students learn about cells and heredity. Our findings suggest…

It has long been noted in research literature that there does not exist a shared definition of integration of science and mathematics. Classifying a particular set of integration practices by one of many labels has limited value. Moving past the definition debate, this study describes the development and testing of the Mathematics Integrated into…

Chia seeds will sprout on almost any moist surface, and they respond quickly to experimental variables. Furthermore, the newly recognized nutritional value and rich cultural history of chia seeds offer the possibility of highly motivating and educational interdisciplinary extensions, especially appropriate to students in the middle grades.…

Throughout this action research project report, the teacher-researchers explored the problem of test anxiety among students. The purpose of this project was to alleviate test anxiety among students with various interventions in grades five through seven in the subject areas of social studies, science, and language arts. There were 66 student…

The ocean provides humanity with many services and goods, including clean air, minerals, and food. Sustainable use and management of our marine resources are important to ensure that these resources are available for future generations. The turn-based activity presented in this article teaches students the challenges of managing a sustainable…

By providing a variety of strategies, scenarios, examples of student writing, classroom video clips from across all science content areas, rubrics, and guidelines for designing assessment items, "Supporting Grade 5-8 Students in Constructing Explanations in Science: The Claim, Evidence, and Reasoning Framework for Talk and Writing" provides…

Researchers in the areas of psychology and education strive to understand the intersections among validity, educational measurement, and cognitive theory. Guided by a mixed model conceptual framework, this study investigates how respondents' opinions inform the validation argument. Validity evidence for a science assessment was collected through…

Imagine recreating a tsunami's force in a bathtub or exploring the potential of geothermal energy by using steam from a kettle to illuminate a light bulb. These types of activities and more are offered in Matthew Levy and Mario Salvadori's collection of experiments and demonstrations in Earthquakes, Volcanoes and Tsunamis. More than 30 easy and…

Modeling is a core practice in science and a central part of scientific literacy. We present theoretical and empirical motivation for a learning progression for scientific modeling that aims to make the practice accessible and meaningful for learners. We define scientific modeling as including the elements of the practice (constructing, using,…

The purpose of the study was to describe the development and application of an instrument to identify various dimensions of the learning environment, as perceived by elementary and middle school students in Taiwan. The instrument, the New Constructivist Learning Environment Scales, includes four dimensions: attitude concerning instruction,…
