Remijan, Kelly W. – Mathematics Teacher, 2019
Just as steam was found to be a source of power during the Industrial Revolution, increasing factory production and improving transportation, today STEAM (Science, Technology, Engineering, Art, and Mathematics) can be found to be a framework that empowers teachers, increases student engagement, and improves student understanding. Although a…

Wood, Marcy B.; Sheldon, James; Felton-Koestler, Mathew D.; Oslund, Joy; Parks, Amy Noelle; Crespo, Sandra; Featherstone, Helen – Teaching Children Mathematics, 2019
Thinking about students in terms of participation instead of "high" or "low" achievers is more than replacing one term with another; it encourages us to shift our focus to student activity as well as barriers to and supports for productive activity. It encourages us to create classroom spaces that draw on student strengths and…

Edwards, Thomas G.; Chelst, Kenneth R. – Mathematics Teacher, 2019
While tutoring his granddaughter in second-year algebra recently, the second author lamented that every textbook he could find expresses the quadratic formula as probably the most common form of the formula. What troubled him is that this form hides the meaning of the various components of the equation. Indeed, the meaning was obscured by the…

Clark, Sarah; Newberry, Melissa – Asia-Pacific Journal of Teacher Education, 2019
Teacher education programs are under great pressure to produce highly capable teachers. Teacher self-efficacy has been shown to correlate with teacher motivation and perseverance, yet little is known about how specific teacher education experiences predict teacher self-efficacy. Four sources contributing to teacher self-efficacy beliefs during…

Frabasilio, Angela Marie – Mathematics Teaching in the Middle School, 2019
Ever try to captivate students with real-world applications only to discover that they live in a very different world? Assigning an Extreme Word Problem activity to students alleviates this dilemma by placing the authorship of a problem squarely into the hands of learners. Rather than trying to be hip and finding word problems that resonate with…

Chu, Haiwen; Hamburger, Leslie – Mathematics Teaching in the Middle School, 2019
All students need to discuss mathematics to develop and deepen understanding. However, for English Learners (ELs), peer dialogue is imperative and indispensable to conceptual understanding as they participate in mathematical practices and engage in increasingly sophisticated uses of language (Heritage, Walqui, and Linquanti 2015). As ELs share…

Sela, Hagit; Davis, Nicole; Hulse, Jennifer – Mathematics Teaching in the Middle School, 2019
In education, "dialogue protocols," or "protocols," are structured guidelines that were developed to promote meaningful and efficient communication and learning. They are "vehicles for building the skills--and culture-- necessary for collaborative work. The authors share protocols that were found to transform practices…

Russell, Craig – Mathematics Teacher, 2019
Although social studies or language arts classes may offer more natural settings for "global studies," the author's students have engaged in projects demonstrating that mathematical topics can work well at furthering the goal of increasing students' cultural literacy. The author describes one project here, where students working in…

Kean, Kelsey M.; van Zee, Kari; Mehl, Ryan A. – Journal of Chemical Education, 2019
The content and design scheme for a readily adaptable, research-based laboratory course in chemical biology are presented. In this course, students interrogate protein structure and function using the site-specific incorporation of noncanonical amino acids by genetic code expansion. The relatively new field of genetic code expansion enables…

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…

Elliott, Leslie Atkins; Sippola, Elizabeth; Watkins, Jeffrey – Journal of Chemical Education, 2019
In this article, we describe how the Gaussian Gun, a simple configuration of magnets and ball bearings, can be leveraged to connect ideas from physics to representations and ideas that are central to chemistry and challenging for students to learn. In particular, we show how the Gaussian Gun, an arrangement of ball bearings and magnets, models…

Neuman, Annette W.; Harmon, Brenda B. – Journal of Chemical Education, 2019
An integrated lab-lecture project, known as the mini research project, was developed for a medicinal chemistry course for nonscience majors. In the lecture component of this project, students choose a plant essential oil with documented biological activity and prepare a literature review describing the importance, history, and current use of the…

Grosso, Carla; Liber, Marta; Brigas, Amadeu F.; Pinho e Melo, Teresa M. V. D.; Lemos, Américo – Journal of Chemical Education, 2019
Regioselectivity in hetero Diels-Alder reactions can be observed in a simple reaction between a nonsymmetrical heterodiene and an unsymmetrical heterodienophile. A 9 h and easy to implement laboratory experiment is described, in which students can observe the regioselectivity of inverse "electron-demand" hetero Diels-Alder reactions of…

Calcabrini, Mariano; Onna, Diego – Journal of Chemical Education, 2019
The study of gels and their properties is a compelling topic both technologically and scientifically, and should therefore be emphasized in chemistry and material science syllabuses. In the present laboratory experiment, we propose two experiences, aimed at introducing gelation and gel transport properties using silica gels made from sodium…

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…
