We present an interactive discovery-based approach to studying the properties of real gases using simple, yet realistic, molecular dynamics software. Use of this approach opens up a variety of opportunities for students to interact with the behaviors and underlying theories of real gases. Students can visualize gas behavior under a variety of…

Inquiry methods have been successful in improving science literacy in students of all ages. Model-Based Inquiry (MBI) is an instructional model that engages students in the practices of science through the collaborative development of scientific models to explain an anchoring phenomenon. Student ideas are tested through engagement in content-rich…

In response to the authors, I demonstrate how threshold concepts offer a means to both contextualise teaching and learning of quantum physics and help transform students into the culture of physics, and as a way to identify particularly troublesome concepts within quantum physics. By drawing parallels from my own doctoral research in another area…

This paper reports on the results from administering a modified version of the Introductory Astronomy Questionnaire (IAQ) to middle school students and preservice science teachers in Norway. Ranking tasks formed a key part of the instrument, and we detail a new method for analyzing ranking task data. One of our main findings was that even after…

The purpose of the study was to identify and analyse high school students' metaphorical perceptions of biology and biology teacher concepts. The sample comprised all the 515 students studying in the Etimesgut district in Ankara in the spring semester of the 2015/2016 academic year. The data were gathered through a form which included the phrases…

This paper introduces Ladders of Learning (LLs) as a tool for structuring learning content and the teaching process in a transparent way for students. Learning material for a LL for Bohr's atomic model was developed by cooperation between chemistry teachers and university researchers and implemented in grade-eight chemistry classes. For evaluating…

This study analyzes the impact of signaling principles upon the effective use of interactive learning media. Normally, designers just design and develop learning media for use in schools without considering the way it eases users' tasks. Bearing in mind that signaling users while they are learning through interactive learning media is important,…

The aim of this research is to develop a measurement instrument that is valid and reliable, called the Middle School-Life Science Concept Inventory (MS-LSCI), for the purpose of measuring the life science conceptual understanding of middle school-level students. Although there are several existing concept inventories related to biology concepts…

Teaching and learning with simulations is widely used in today's classrooms. Therefore, it is important to examine the factors that potentially influence the effectiveness of simulation-based teaching environments. The aim of this research was to compare the effectiveness of teacher-centered and student-centered Physlet-based classes about…

Young's double-slit experiment is one of the most historically significant works in physics, and one that is easily done in an introductory physics class. It is also an excellent example of an investigation that allows us to infer the nature of phenomena beyond direct observation. Unfortunately, perhaps because of this, it is often also an…

Previous work covers building a tower from a stack of homogeneous rectangular plates, each with a maximum shift in displacement. We suggest using plates shaped as curvilinear triangles bounded by segments of power-law functions. The masses of the plates and the position of their center of mass are calculated and measured experimentally after…

Lens imaging is a classic topic in physics education. To guide students from their holistic viewpoint to the scientists' analytic viewpoint, an image-based approach to lens imaging has recently been proposed. To study the effect of the image-based approach on undergraduate students' ideas, teaching experiments are performed and evaluated using…

The purpose of this research was to explore children's understandings of everyday, synthetic and scientific concepts to enable a description of how abstract, verbally taught material relates to previous experience-based knowledge and the consistency of understanding about cloud formation. This study examined the conceptual understandings of cloud…

Potentiometric titrations are widely taught in first-year undergraduate courses to connect electrochemistry, stoichiometry, and equilibria and to reinforce acid-base titrations. Students perform a potentiometric titration that is then analyzed to determine analyte concentrations and the solubility product constant of the solid species.

We describe a 2 h introductory laboratory procedure that prepares a novel magnetic antimicrobial activated carbon nanocomposite in which nanoscale sized magnetite and silver particles are incorporated (MACAg). The MACAg nanocomposite has achieved the synergistic properties derived from its components and demonstrated its applicability as an…
