Park, Han Jung; Kurien, Neethu M.; Rybolt, Thomas R. – Journal of Chemical Education, 2018
We report here a method that utilizes the vapor pressure of HCl(g) above a concentrated HCl(aq) solution as an extremely simple and safe method to produce small amounts of HCl vapor in an IR gas cell. This vapor pressure approach can also be used to produce DCl(g) by introducing a few drops of concentrated DCl(aq) into the gas cell.

Katz, Louise; Lambert, Warren – Teaching of Psychology, 2016
Although there have been many suggestions for incorporating cell phone use into classroom activities, there have been few suggestions for removing cell phone use from the classroom. This article presents an easy-to-implement method using positive reinforcement that effectively removes cell phones from the classroom in a way that is highly endorsed…

Ragazzini, Gregorio; Mescola, Andrea; Corsi, Lorenzo; Alessandrini, Andrea – Journal of Biological Education, 2019
In recent years the possibility of observing by microscopy the dynamic activity of living cells has been largely pursued. We have developed a low-cost (~ 260 euros) on-stage cell incubator for inverted optical microscopes. This device allows to keep cells in good conditions for their survival and proliferation. The device is based on the use of…

Chiverton, Scott – English Teaching Forum, 2017
Those of us in North America, Europe, many parts of Central and South America, and eastern Asia live in a digital world, and there has been ongoing debate about technology and learning. In other parts of the world, such as the African continent and much of central and south central Asia, there is evidence of a digital invasion, but it is still not…

Ibarguren, Izaskun; Villamarín, Antonio – Journal of Biological Education, 2017
All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and, consequently, it contains a particular set of proteins that determine its function. Here, we describe a laboratory exercise addressed to undergraduate students that aims to…

Nagel, Thomas; Mentzer, Casey; Kivistik, P. Mike – Journal of Chemical Education, 2019
This experiment provides students with a thorough understanding of electrolysis and the parameters that most greatly impact optimization of this process. In this laboratory exercise, students will focus on the anodization of bismuth metal to develop thin oxide films. When designing an electrolytic cell devoted to anodization, there are several…

Storch, Sharon L.; Juarez-Paz, Anna Victoria Ortiz – International Journal of Mobile and Blended Learning, 2019
Through qualitative measures, this article seeks to explore the efficacy of cell phones within college level instructional design specifically through the eyes of the professor. Three main themes evolved from this data: Pedagogical Approaches, Value, and Setting Behavioral Expectations. Based on interviews with ten college professors regarding…

de Oliveira, Mayara Lustosa; Galembeck, Eduardo – Journal of Biological Education, 2016
Cell biology apps were surveyed in order to identify whether there are new approaches for modelling cells allowed by the new technologies implemented in tablets and smartphones. A total of 97 apps were identified in 3 stores surveyed (Apple, Google Play and Amazon), they are presented as: education 48.4%, games 26.8% and medicine 15.4%. The apps…

Ivaldi, Silvia; Scaratti, Giuseppe – Journal of Workplace Learning, 2016
Purpose: The aim of the paper is to analyze the process of "germ cell" formation by framing it as an opportunity for promoting organizational learning and transformation. The paper aims to specifically answer two research questions: Why does the "germ cell" have a pivotal role in organization's transformation? and Which…

Thomas, Kevin M.; O'Bannon, Blanche W.; Bolton, Natalie – Computers in the Schools, 2013
Historically viewed as a disruption by teachers, cell phones have been banned from 69% of classrooms (Common Sense Media, 2009). The increased ubiquity and instructional features of cell phones have prompted some teachers to re-evaluate the ban and consider the benefits associated with allowing cell phones in the classroom. This study surveyed 79…

Hindman, Annemarie H.; Wasik, Barbara A. – Early Child Development and Care, 2017
The current study examined whether Head Start children who experienced a high-quality preschool intervention, "Exceptional Coaching for Early Language and Literacy" ("ExCELL"), as three-year-olds began the subsequent pre-kindergarten (or four-year-old) year with stronger language and literacy skills than same-age peers who…

Cottrell, Vicki M. – School Science Review, 2013
African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and…

Goudsouzian, Lara K.; Riola, Patricia; Ruggles, Karen; Gupta, Pranshu; Mondoux, Michelle A. – Biochemistry and Molecular Biology Education, 2018
Multiple pedagogical approaches, such as experimental experiences or computer-based activities, have been shown to increase student learning and engagement. We have developed a laboratory module that includes both a traditional "live" experimental component and a student-designed "virtual" computer simulation component. This…

Jenaro, Cristina; Flores, Noelia; Cruz, Maribel; Pérez, Ma Carmen; Vega, Vanessa; Torres, Víctor A. – Journal of Applied Research in Intellectual Disabilities, 2018
Background: The risks and opportunities associated with the use of technologies are of growing research interest. Patterns of technology usage illuminate these opportunities and risks. However, no studies have assessed the usage patterns (frequency, duration, and intensity) and related factors in young people with intellectual disabilities.…
