Bradley J. Morris; Jacob Cason; Katie Asaro; Yin Zhang; Michelle Rivers; Whitney Owens; John Dunlosky – International Journal of Science Education, 2025
Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…

Wei, Bing; Jiang, Zhimeng; Gai, Lichun – Science & Education, 2022
Practical work is a distinctive feature of school science and has close associations with scientific experiment and scientific methods as well. In this study, the nature of practical work was examined in the view of the diversity of scientific methods. Based on an analytical framework derived from Brandon's matrix consisting of four categories of…

Xu, Beichen; Su, Jun; Wang, Weiguo – Physics Education, 2018
Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

Sabag, Tali; Tabak, Iris – AERA Online Paper Repository, 2017
The Teacher as Partner is an approach to inquiry-based science teaching, where the teacher works as the students' partner. Prior research suggests that it offers an opportunity to model inquiry actions and voice their often tacit rationale. It also enables learners to witness the difficulties and fallibility that even experts can experience, which…

Allen, Michael – Research in Education, 2015
A medium-scale quantitative study (n = 90) found that 10-11-year-old pupils dealt with theory and evidence in notably different ways, depending on how the same science practical task was delivered. Under the auspices of a 2×2 part-randomised and part-quasi experimental design, pupils were asked to complete a brief, apparently simple task involving…

Kuhn, Jochen; Lukowicz, Paul; Hirth, Michael; Poxrucker, Andreas; Weppner, Jens; Younas, Junaid – IEEE Transactions on Learning Technologies, 2016
Smart Glasses such as Google Glass are mobile computers combining classical Head-Mounted Displays (HMD) with several sensors. Therefore, contact-free, sensor-based experiments can be linked with relating, near-eye presented multiple representations. We will present a first approach on how Smart Glasses can be used as an experimental tool for…

Longo, Christopher M. – Middle School Journal (J1), 2011
Mr. Smith and Ms. D'Amico are two veteran science teachers in a well-performing school district. Both teachers use weekly lab exercises and experiments as formative assessments. In their middle school classrooms, children are engaged and eager to learn. As students walk into Mr. Smith's classroom, a prescribed, step-by-step procedure of the day's…

Ketelhut, Diane Jass; Nelson, Brian C. – Educational Research, 2010
Background: Most policy doctrines promote the use of scientific inquiry in the K-12 classroom, but good inquiry is hard to implement, particularly for schools with fiscal and safety constraints and for teachers struggling with understanding how to do so. Purpose: In this paper, we present the design of a multi-user virtual environment (MUVE)…

Zucker, Andrew A.; Tinker, Robert; Staudt, Carolyn; Mansfield, Amie; Metcalf, Shari – Journal of Science Education and Technology, 2008
The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3-8. Each unit uses computers and probeware to support students' investigations of real-world phenomena using probes (e.g., for temperature or…
