Campbell, Dean J.; Staiger, Felicia A.; Jujjavarapu, Chaitanya N. – Journal of Chemical Education, 2015
The whoosh bottle rocket car has been redesigned to be more reusable and more robust, making it even easier to use as a demonstration. Enhancements of this demonstration, including the use of heat sensitive ink and electronic temperature probes, enable users to find warmer and cooler regions on the surface of the whoosh bottle.

Zhu, Guangtian; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2013
We describe the difficulties advanced undergraduate and graduate students have with concepts related to addition of angular momentum in quantum mechanics. We also describe the development and implementation of a research-based learning tool, Quantum Interactive Learning Tutorial (QuILT), to reduce these difficulties. The preliminary evaluation…

Roy, Arunava – Physics Teacher, 2011
The European Center for Nuclear Research or CERN's Large Hadron Collider (LHC) has caught our attention partly due to the film "Angels and Demons." In the movie, an antimatter bomb attack on the Vatican is foiled by the protagonist. Perhaps just as controversial is the formation of mini black holes (BHs). Recently, the American Physical Society…

Putti, Alice – Science Teacher, 2012
This guided inquiry activity was developed to help students "view" an equilibrium system from the particulate level and make connections to their macroscopic observations. Part I helps students observe a physical equilibrium system in which water is transferred between two larger containers. In Part II, students examine what happens to a chemical…

Ganci, Salvatore – Physics Education, 2011
This paper describes a set of simple experiments with a very low cost using a notebook as a measuring instrument without external hardware. The major purpose is to provide demonstration experiments for schools with very low budgets. (Contains 6 figures.)

Scherger, Nicole – MathAMATYC Educator, 2012
Of the most universal applications in integral calculus are those involved with finding volumes of solids of revolution. These profound problems are typically taught with traditional approaches of the disk and shell methods, after which most calculus curriculums will additionally cover arc length and surfaces of revolution. Even in these visibly…

Koser, John – Physics Teacher, 2011
Students in introductory physics courses often don't study thermodynamics or thermodynamic events. If any thermal physics is taught in introductory courses (e.g., Physics 101 for Liberal Arts Majors), it usually involves the concepts of specific heat and various temperature scales. Seldom are the first and second laws of thermodynamics taught in…

Millar, Thomas James; Knighton, Ronald; Chuck, Jo-Anne – Biochemistry and Molecular Biology Education, 2012
Immunological detection of proteins is an essential method to demonstrate to undergraduate biology students, however, is often difficult in resource and time poor student laboratory sessions. This method describes a failsafe method to rapidly and economically demonstrate this technique using biotinylated proteins or biotin itself as targets for…

Swapp, Andy; Schreuders, Paul; Reeve, Edward – Technology and Engineering Teacher, 2011
Many people use wind to help meet their needs. Over the years, people have been able to harness or capture the wind in many different ways. More recently, people have seen the rebirth of electricity-generating wind turbines. Thus, the age-old argument about technology being either good or bad can also be applied to the wind. The wind can be a…

Subramaniam, Karthigeyan – Clearing House: A Journal of Educational Strategies, Issues and Ideas, 2012
This article examines the merits of WebQuests in facilitating students' in-depth understanding of science concepts using the four principles of learning gathered from the National Research Council reports "How People Learn: Brain, Mind, Experience, and School" (1999) and the "How Students Learn: Science in the Classroom" (2005) as an analytic…

Lehman, James D.; Kim, WooRi; Harris, Constance – Journal of STEM Education: Innovations and Research, 2014
The new standards for K-12 science education in the United States call for science teachers to integrate engineering concepts and practices within their science teaching in order to improve student learning. To accomplish this, teachers need appropriate instructional materials as well as the knowledge and skills to effectively use them. This mixed…

Sisk, Dorothy A. – Gifted and Talented International, 2010
This article presents the author's response to Hisham B. Ghassib's article entitled "Where Does Creativity Fit into a Productivist Industrial Model of Knowledge Production?" Ghassib (2010) outlines a Productivist Industrial Model of Knowledge Production, in which he calls the knowledge enterprise an industry in which creativity and innovation play…

Makarevitch, Irina; Kralich, Elizabeth – Biochemistry and Molecular Biology Education, 2011
Open-ended, inquiry-based multiweek laboratory exercises are the key elements to increasing students' understanding and retention of the major biological concepts. Including original research into undergraduate teaching laboratories has also been shown to motivate students and improve their learning. Here, we present a series of original…

Pantaleao, Ines; Portugal, Ana F.; Mendes, Adelio; Gabriel, Joaquim – Journal of Chemical Education, 2010
A pedagogical experiment is described to examine the physical absorption of gases, in this case carbon dioxide, in a hollow fiber membrane contactor (HFMC) where the absorption concentration profile can be followed by a color change. The HFMC is used to teach important concepts and can be used in interesting applications for students, such as…

Rowland, Susan L.; Smith, Christopher A.; Gillam, Elizabeth M. A.; Wright, Tony – Biochemistry and Molecular Biology Education, 2011
A strong, recent movement in tertiary education is the development of conceptual, or "big idea" teaching. The emphasis in course design is now on promoting key understandings, core competencies, and an understanding of connections between different fields. In biochemistry teaching, this radical shift from the content-based tradition is…
