Ramdiah, Siti; Abidinsyah; Royani, M.; Husamah – International Journal of Instruction, 2019
Higher-order Thinking Skills (HOTS) is significant for students and has to be trained and managed well by teachers. This study aims to describe the preparation of biology teachers in learning, to analyze the understanding of biology teachers about HOTS, and to examine the efforts of biology teachers in developing HOTS for high school students in…

Limpanuparb, Taweetham; Kanithasevi, Siradanai; Lojanarungsiri, Maytouch; Pakwilaikiat, Puh – Journal of Chemical Education, 2019
We discuss the use of a simple piece of equipment made of a 50 mL syringe attached to a 2 mL graduated pipet to demonstrate Boyle's law and Charles's law. A plot of the hydrostatic pressure against the reciprocal of the volume of the gas read from the equipment is linear as discussed in the paper and gives the atmospheric pressure at the…

Alho, J.; Silva, H.; Teodoro, V.; Bonfait, G. – Physics Education, 2019
In the field of physics teaching, the simple pendulum provides a very simple way to study the harmonic oscillator, the source of some fundamental concepts such as periodicity, relaxation time and anharmonicity. As such, its experimental study is frequently integrated into high school or first year university programs. With this in mind, in this…

Rosi, Tommaso; Gratton, Luigi M.; Onorato, Pasquale; Oss, Stefano – Physics Education, 2019
We propose to reconsider the well-known experiment about the interference of white light from a thin soap film by adopting as an illuminating source the RGB triad produced by a LED projector. The interference pattern shows up in a particularly fascinating way and it contains direct, essential information about both the wave nature of light and of…

de Jesus, V. L. B.; Pérez, C. A. C.; de Oliveira, A. L.; Sasaki, D. G. G. – Physics Education, 2019
Currently, the number of smartphones with an embedded gyroscope sensor has been increasing due games whose performance relies on 3D augmented reality. In general, teaching papers on the gyroscope sensor address very simple spatial configuration, where the fixed rotation axis coincides to the z-axis of the smartphone. This work presents five…

Ait Tahar, M.; Schadschneider, A.; Stollenwerk, J. – Physics Education, 2019
This article is about the development of an Internet-based remotely-controlled physical experiment, this is a part of the Remotely Controlled Laboratory at the University of Applied Sciences of Cologne known as TH Köln. The main experimental set-up is based on Pohl's Torsion Pendulum which was enhanced by a PXI measurement system and a webcam. In…

Warehime, Shane; Snyder, Kailey; Schaffer, Connie; Bice, Matthew; Adkins-Bollwit, Megan; Dinkel, Danae – Physical Educator, 2019
This study explored the use of classroom physical activity (PA) in secondary science classrooms. To accomplish this, semistructured interviews were conducted with secondary science teachers (n = 11). Interviews were based on the constructs of the social-ecological model. Most teachers reported using classroom PA in some form--in-class breaks,…

LeSuer, Robert J. – Journal of Chemical Education, 2019
Consumer-grade manufacturing tools such as 3D printers are becoming increasingly prevalent in STEM education environments, especially as tools to develop inexpensive, tactile visualization models. Presented here is a workflow for creating 3D-printed periodic tables displaying a variety of trends from traditionally taught relationships such as…

Wiggins, Marcie B.; Heath, Emma; Alcántara-García, Jocelyn – Journal of Chemical Education, 2019
The interface of art and science provides a broad range of educational and collaborative projects at various learning stages. Therefore, the use of historic artists' materials for teaching chemistry is receiving more attention. We prepared and used copper acetate (verdigris pigment) for a series of interconnected, lab-based activities, which can…

Dean, Natalie L.; Ewan, Corrina; Braden, Douglas; McIndoe, J. Scott – Journal of Chemical Education, 2019
Comprehension of the 3D structure of objects usually represented in 2D is a critical part of understanding molecular geometries. The frequency with which students actually get hands-on with 3D molecular structures is often limited to a singular laboratory session. We sought to develop a set of molecular shapes that were inexpensive enough not only…

Erdem, Aytekin – Journal of Education and Training Studies, 2019
This study was carried out to determine teacher views on the use of technology to improve physics education in high schools. The sample of the study is 238 volunteer physics teachers. The study was carried out with the survey model and a five point Likert Scale was used in the study. The scale has a reliability coefficient of 0.92. Descriptive and…

Mahanal, Susriyati; Zubaidah, Siti; Sumiati, Ika Dewi; Sari, Tri Maniarta; Ismirawati, Nur – International Journal of Instruction, 2019
The purpose of this study was to investigate the effect of RICOSRE learning models towards critical thinking skills of students with different academic abilities. This quasi-experimental study employed a pretest-posttest nonequivalent control group design and involved all the eleventh-grade students from high schools in Malang, Indonesia. The…

Stankus, Brian; White, Rosemary; Abrams, Binyomin – Journal of Chemical Education, 2019
Chromatography is a ubiquitous technique in analytical chemistry, and high-performance liquid chromatography (HPLC) is the industry standard for quantitation of components in solution mixtures. However, demonstrating the principles of liquid chromatography to undergraduates via HPLC-based experiments often proves ineffective because of the fully…

Minkiewicz, Piotr; Darewicz, Malgorzata; Iwaniak, Anna – Journal of Chemical Education, 2018
A simple equation to calculate the oxidation states (oxidation numbers) of individual atoms in molecules and ions may be introduced instead of rules associated with words alone. The equation includes two of three categories of bonds, classified as proposed by Goodstein: number of bonds with more electronegative atoms and number of bonds with less…

Wietsma, Jan Jaap; van der Veen, Jan T.; Buesink, Wilfred; van den Berg, Albert; Odijk, Mathieu – Journal of Chemical Education, 2018
Lab-on-a-chip technology is brought into the classroom through development of a lesson series with hands-on practicals. Students can discover the principles of microfluidics with different practicals covering laminar flow, micromixing, and droplet generation, as well as trapping and counting beads. A quite affordable novel production technique…
