Though science teachers use curricular materials from a range of sources, the nature of the science education materials that exist in the public domain or that are licensed for free use has not been the focus of much prior research. In this study, Open Educational Resources (OER) that can be accessed through the OER Commons platform were examined…

Previous educational articles on microfluidic technology mainly focused on continuous microfluidics, so we set up an undergraduate laboratory experiment to introduce droplet microfluidics to students. Students can understand the concept of microfluidic channels and the principles of droplet microfluidics, prepare polydimethylsiloxane (PDMS)…

Recent work in science education has emphasized the importance of the conceptual, social, and epistemic dimensions in science learning. But what about the material dimension--the actual physical materials that students use? The way their characteristics and affordances limit or determine instruction has thus far not been as thoroughly explored.…

Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…

In this article, we analyze images from the book "Our Friend the Atom," written by the astrophysicist Heinz Haber in 1957 and developed in the Disney Science Department. In addition to analyzing the work, we investigate its relevance for science education. After the US attack on two Japanese cities with atomic bombs, there was a…

Teaching and learning relies on age-appropriate, credible formal (e.g., textbooks, textbook supplements) and informal (e.g., trade-books) curricular texts. Previous research traced American publishers' self-censorship about human evolution within twentieth-century textbooks. This study, informed by the latest scientific understandings, engaged in…

Comparing comprehension outcomes in print and digital reading is an active area of research but little is known about the reading processes that these media entail. This study involved an eye-tracking experiment with 50 undergraduate students to investigate the differences in reading processes in print and digital media. The participants were…

This article describes how kindergarten scientists at Caldwell Heights Elementary School in Round Rock, Texas created what they named a "Light Circle" using their classroom's south-facing window, its windowsill, and a small round mirror. The tilt of the Earth and the latitude of one's location combine to determine if the Sun ever shines…

Optical polarization phenomena are omnipresent in physics, chemistry, biology, and technology. Studying optical polarization is best done through an interdisciplinary approach that combines biology and technology, which usually makes things more interesting to students. Seeing Haidinger's brush for the first time can be an exciting discovery for…

This study aimed to: 1) assess the impact of a STEAM education learning package on grade 10 students' science process skills, 2) evaluate its effect on their learning achievement concerning the physical properties of materials, and 3) gauge the students' satisfaction with the learning package. The participants were 13 grade 10 students from a…

This study investigates text readability level investigation about biology subjects-related units in 'Science 7 Textbook'. A document analysis method was used in this study based on a qualitative research approach. The textbook, which has been used since the 2019-2020 academic year, has been selected as the study material. In the textbook, a total…

Prompting students to generate constructed responses as they read provides a window into the processes and strategies that they use to make sense of complex text. In this study, Markov models examined the extent to which: (1) patterns of strategies; and (2) strategy combinations could be used to inform computational models of students' text…

Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

Writing instruments, such as pens, are ubiquitous in the classroom, but their functionality is largely for one purpose: they are used to represent ideas and record information on paper. However, by replacing the conventional ink in a pen with easy-to-synthesize conducting polymer-based inks, it is possible to change a simple writing utensil into a…

Retrieval practice enhances the learning of educational materials, and prior work has shown that practicing retrieval can enhance learning as much as or more than creating concept maps. Few studies have combined retrieval practice with other learning activities, and no prior work has explored whether concept mapping and retrieval practice might…
