Merricks, Jessica; Lankford, Deanna – Science and Children, 2019
For some elementary science teachers, a unit on land and water brings nightmares of dirt and water all over the room. Several Earth science "kits" contain hands-on exercises that allow the students to "get messy" as they manipulate materials; however, these lessons may lack the necessary opportunities for students to ask unique…

Fedick, Patrick W.; Schrader, Robert L.; Ayrton, Stephen T.; Pulliam, Christopher J.; Cooks, R. Graham – Journal of Chemical Education, 2019
Process analytical technologies (PATs) are used in the pharmaceutical and other industries to monitor chemical processes in real-time with analytical instrumentation. Each PAT analyzer brings its own advantages and disadvantages to the process, and multiplexing PAT analyzers can be advantageous as they can provide confirmatory measurements and…

Kwan, Ann H.; Mobli, Mehdi; Schirra, Horst J.; Wilson, Jennifer C.; Jones, Oliver A. H. – Journal of Chemical Education, 2019
Magnetic resonance is a powerful technology that has had a major impact across the physical, life, and medical sciences, from chemistry to medical imaging, with ever-expanding applications in new areas as diverse as mining and food science. It is, however, also a difficult subject to teach, as the theory is complex and requires some familiarity…

Neat, Adam – Physics Teacher, 2019
How far, in space, can we see? And can we see an object whose Hubble recessional velocity exceeds the speed of light? Maybe you've thought about these questions before, or perhaps you've seen them discussed in the literature or mentioned in the media. With the recent popularity of inflation and Big Bang cosmology, they're hard to avoid. The…

Holbert, Nathan; Wilensky, Uri – Journal of the Learning Sciences, 2019
In this article we propose that educational game design should work to create games as objects-to-think-with--games that engage players in the exploration of and experimentation with personally interesting questions around domain-relevant representations. We argue that this design focuses on developing tools and interactions that the player can…

Shen, Jie – Interactive Learning Environments, 2019
Excellent film is an integrated art. It has rich knowledge and profound ideological connotations. In order to promote students' enthusiasm for learning about biology, we made some attempts on how to use movie clips for biological teaching and achieved good results. Making use of movie's sound, color, light, and animations, we tried to enrich…

Schenk, Linda; Hamza, Karim M.; Enghag, Margareta; Lundegård, Iann; Arvanitis, Leena; Haglund, Karin; Wojcik, Andrzej – International Journal of Science Education, 2019
The present paper takes its point of departure in risk being a relevant content for science education, and that there are many different approaches to how to incorporate it. By reviewing the academic literature on the use and definitions of risk from fields such as engineering, linguistics and philosophy, we identified key elements of the risk…

Vollmer, Michael; Möllmann, Klaus-Peter – Physics Education, 2018
Video analysis with a 30 Hz frame rate is the standard tool in physics education. The development of affordable high-speed-cameras has extended the capabilities of the tool for much smaller time scales to the 1 ms range, using frame rates of typically up to 1000 frames s[superscript -1], allowing us to study transient physics phenomena happening…

do Carmo, Eduardo; Hönnicke, Marcelo Goncalves – Physics Education, 2018
There are different forms to introduce/illustrate the energy concepts for the basic physics students. The explosive seed dispersal mechanism found in a variety of trees could be one of them. Sibipiruna trees carry out fruits (pods) who show such an explosive mechanism. During the explosion, the pods throw out seeds several meters away. In this…

Erol, M.; Çolak, I. Ö. – Physics Education, 2018
This paper reports a simple magnetically driven oscillator, designed and resolved in order to achieve a better student understanding and to overcome certain instructional difficulties. The apparatus is mainly comprised of an ordinary spring pendulum with a neodymium magnet attached to the bottom, a coil placed in the same vertical direction, an…

Kattmann, Ulrich – School Science Review, 2018
Should entropy and energy be emphasised as relevant concepts for biology education? This question will be discussed, highlighting the ways in which the concepts of entropy and energy can contribute to a better understanding of biological processes. Organisms are open systems. Therefore, the chosen perspective is different from the traditional…

Levine, Zachary H. – Physics Teacher, 2018
An attempt to calibrate a conventional oven led to making a measurement of a thermophysical property of water using items found in the author's home. Specifically, the ratio of the energy required to heat water from the melting point to boiling to the energy required to completely boil away the water is found to be 5.7. This may be compared to the…

Jacobs, Greg C. – Physics Teacher, 2018
The Tasks Inspired by Physics Education Research (TIPERS) workbooks pose questions in styles quite different from the end-of-chapter problems that those of us of a certain age were assigned back in the days before Netscape. My own spin on TIPERS is not just to do them on paper, but to have students set up the situations in the laboratory to…

Alameh, Sahar; Abd-El-Khalick, Fouad – Science & Education, 2018
Stemming from the realization of the importance of the role of explanation in the science classroom, the Next Generation Science Standards (NGSS Lead States 2013) call for appropriately supporting students to learn science, argue from evidence, and provide explanations. Despite the ongoing emphasis on explanations in the science classroom, there…

Ribeiro, Jair Lúcio Prados – Physics Teacher, 2018
We only became aware of the existence of bed prism spectacles when a student brought them to the classroom and asked us about how they work. The device proved to be a fertile source of curiosity among the students, and, to be properly understood, it required us to develop a comparison between reflection in a typical mirror and total internal…
