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…

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…

Koh, Sam Boon Kiat; Fung, Fun Man – Journal of Chemical Education, 2018
A mobile application game has been adapted to teach students about laboratory instruments, glassware, apparatus, and techniques. The game was designed with reference to a popular icebreaker game, "Charades!", to ensure that it was easily accessible to students. Students will hold a mobile phone just above their forehead, which will then…

Mac Fhionnlaoich, Niamh; Ibsen, Stuart; Serrano, Luis A.; Taylor, Alaric; Qi, Runzhang; Guldin, Stefan – Journal of Chemical Education, 2018
Thin-layer chromatography (TLC) is one of the basic analytical procedures in chemistry and allows the demonstration of various chemical principles in an educational setting. An often-overlooked aspect of TLC is the capability to quantify isolated target compounds in an unknown sample. Here, we present a suitable route to implement quantitative…

Richardson, Janessa; Bachman, Rachel M. – Mathematics Teacher, 2017
This article describes a preservice teacher's imaginative exploration of completing the square through a process of reasoning and sense making. She recounts historical perspectives and her own discoveries in the process of completing the square. Through this process of sense making, she engaged with the content standard of completing the square to…

Coomes, Jacqueline; Lee, Hyung Sook – Mathematics Teaching in the Middle School, 2017
Mathematics teachers want to empower students as mathematical thinkers and doers (NCTM 2000). Specific ways of thinking and doing mathematics were described in the Process Standards (NCTM 2000); they were further characterized as habits of mind (Mark, Goldenberg, and Sword 2010); and more recently, they were detailed in the Common Core's Standards…

Gee, Clifford T.; Kehoe, Eric; Pomerantz, William C. K.; Penn, R. Lee – Journal of Chemical Education, 2017
Proteins are involved in nearly every biological process, which makes them of interest to a range of scientists. Previous work has shown that hand-held cameras can be used to determine the concentration of colored analytes in solution, and this paper extends the approach to reactions involving a color change in order to quantify protein…

Case, Catherine; Whitaker, Douglas – Mathematics Teacher, 2016
In the criminal justice system, defendants accused of a crime are presumed innocent until proven guilty. Statistical inference in any context is built on an analogous principle: The null hypothesis--often a hypothesis of "no difference" or "no effect"--is presumed true unless there is sufficient evidence against it. In this…

Simurdiak, Michael; Olukoga, Olushola; Hedberg, Kirk – Journal of Chemical Education, 2016
A laboratory exercise was devised that allows students to rapidly and fairly accurately determine the iodine value of oleic acid. This method utilizes the addition of elemental bromine to the unsaturated bonds in oleic acid, due to bromine's relatively fast reaction rate compared to that of the traditional Wijs solution method. This method also…

Woelk, Klaus – Journal of Chemical Education, 2015
In a classroom or take-home activity, students are challenged to write their name as a combination of chemical-element symbols and calculate "their" molar mass. Age-appropriate versions ranging from middle school to entry-level college classes are discussed. Acceptable molar-mass suggestions may be used in a competition for the heaviest…

Shultz, Ginger V.; Gere, Anne Ruggles – Journal of Chemical Education, 2015
Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

Hartman, JudithAnn R.; Dahm, Donald J.; Nelson, Eric A. – Journal of Chemical Education, 2015
Studies in cognitive science have verified that working memory (where the brain solves problems) can manipulate nearly all elements of knowledge that can be recalled automatically from long-term memory, but only a few elements that have not previously been well memorized. Research in reading comprehension has found that "lecture notes with…

Ohashi, Atsushi – Journal of Chemical Education, 2015
A high-school third-year or undergraduate first-semester general chemistry laboratory experiment introducing simple-cubic, face-centered cubic, body-centered cubic, and hexagonal closest packing unit cells is presented. Latex balls and acrylic resin plates are employed to make each atomic arrangement. The volume of the vacant space in each cell is…

Scholz, Michael A.; Huynh, Niem Tu; Brysch, Carmen P.; Scholz, Ruojing Wang – Journal of Geography, 2014
Geography textbooks contain chapter or review questions that may engage students in spatial thinking. This research used Jo and Bednarz's (2009) "Taxonomy of Spatial Thinking" to evaluate the percentage of spatial thinking questions in four university-level world geography course textbooks. The results from this study were then…

Figueira, Angela C. M.; Rocha, Joao B. T. – Biochemistry and Molecular Biology Education, 2014
This article presents a problem-based learning (PBL) approach to teaching elementary biochemistry to undergraduate students. The activity was based on "the foods we eat." It was used to engage students' curiosity and to initiate learning about a subject that could be used by the future teachers in the high school. The experimental…
