Marx, Gary – Educational Research Service, 2011
The "Overview" is a condensation of the full Sixteen Trends book. This abbreviated version provides an economical opportunity to order in bulk and distribute copies to an entire school staff, community groups, or other clients and constituents. The "Overview of Sixteen Trends" is an important tool for raising awareness about the need to scan the…

Marks, Patrick; Levine, Mindy – Journal of Chemical Education, 2012
Squaraines are a class of organic fluorophores that possess unique photophysical properties, including strong near-infrared absorption and emission. The synthesis of many squaraines involves the condensation of an electron-rich aromatic ring with squaric acid. These reactions are generally refluxed overnight in a benzene-butanol solvent mixture.…

Neville, Frances; Zin, Azrinawati Mohd.; Jameson, Graeme J.; Wanless, Erica J. – Journal of Chemical Education, 2012
A microscale laboratory experiment for the preparation and characterization of silica particles at neutral pH and ambient temperature conditions is described. Students first employ experimental fabrication methods to make spherical submicrometer silica particles via the condensation of an alkoxysilane and polyethyleneimine, which act to catalyze…

Boudreaux, Andrew; Campbell, Craig – Journal of Chemical Education, 2012
Student understanding of the equilibrium coexistence of a liquid and its vapor was the subject of an extended investigation. Written assessment questions were administered to undergraduates enrolled in introductory physics and chemistry courses. Responses have been analyzed to document conceptual and reasoning difficulties in sufficient detail to…

Duff, David B.; Abbe, Tyler G.; Goess, Brian C. – Journal of Chemical Education, 2012
A multistep synthesis of 5-isopropyl-1,3-cyclohexanedione is carried out from three commodity chemicals. The sequence involves an aldol condensation, Dieckmann-type annulation, ester hydrolysis, and decarboxylation. No purification is required until after the final step, at which point gravity column chromatography provides the desired product in…

Petrlíková, Jarmila – Novitas-ROYAL (Research on Youth and Language), 2013
The term "clause" is not only applied to structures which comply with formal prerequisites, containing a subject and a predicate conveyed by a finite verb, but also to such structures which are analysable into clause elements. The verbless clause is a structure containing no verb element at all (either finite or nonfinite), usually…

Young, Douglas M.; Welker, Jacob J. C.; Doxsee, Kenneth M. – Journal of Chemical Education, 2011
Synthesis of 4-methylumbelliferone via the acid-catalyzed Pechmann condensation introduces students to several types of organic reactions: transesterification, electrophilic aromatic substitution, and alcohol dehydration. Performed with a recyclable, solid catalyst and under solvent-free conditions, the experiment illustrates many of the…

Torenholt, Rikke; Engelund, Gitte; Willaing, Ingrid – Health Education, 2015
Purpose: The purpose of this paper is to examine the use and applicability of cultural probes--an explorative participatory method to gain insights into a person's life and thoughts--to achieve person-centeredness and active involvement in self-management education for people with chronic illness. Design/methodology/approach: An education toolkit…

Lingard, Bob – Educational Philosophy and Theory, 2015
This article responds to and reflects upon the articles in this special issue. Specifically, it deals with the usage of theory in each of the articles, what we might see, as examples of re-descriptive usage in autonomous theorizing. The articles utilize different theories and varying intellectual resources--Foucault and Deleuze (Richard Niesche),…

Herdman, Chelsea; Dickman, Michael – Biochemistry and Molecular Biology Education, 2011
Enzyme stereospecificity and equilibrium thermodynamics can be demonstrated using the coupling of two amino acid derivatives by Thermoase C160. This protease will catalyze peptide bond formation between Z-L-AspOH and L-PheOMe to form the Aspartame precursor Z-L-Asp-L-PheOMe. Reaction completion manifests itself by precipitation of the product. As…

Schmidt-Rohr, Klaus – Journal of Chemical Education, 2015
The strongly exothermic nature of reactions between molecular oxygen and all organic molecules as well as many other substances is explained in simple, general terms. The double bond in O[subscript 2] is much weaker than other double bonds or pairs of single bonds, and therefore the formation of the stronger bonds in CO[subscript 2] and…

Moore, Kimberly A. – ProQuest LLC, 2017
College students are failing to graduate at unacceptable rates (Camera, 2016; DeVore, 2016; Scherer & Anson, 2014; Schneider, 2008). If graduation is the goal, then retention is the means. The research study sought to understand a potential solution to the pervasive retention problem, by researching a new strategy, compassionate enrollment.…

Ebert, Arthur Conrad – ProQuest LLC, 2017
School districts implement a variety of initiatives that too often fall short. This case study investigated how one public school district in southeastern Michigan implemented interest based-bargaining (IBB). The study also sought to understand the factors that influenced the decision-making process and what was considered when making…

Stamovlasis, Dimitrios; Tsitsipis, Georgios; Papageorgiou, George – Chemistry Education Research and Practice, 2012
In this study, structural equation modeling (SEM) is applied to an instrument assessing students' understanding of the particulate nature of matter, the collective properties and physical changes, such as melting, evaporation, boiling and condensation. The structural relationships among particular groups of items were investigated. In addition,…

Benz, Lauren; Cesafsky, Karen E.; Le, Tran; Park, Aileen; Malicky, David – Journal of Chemical Education, 2012
This article describes a simple and inexpensive undergraduate-level kinetics experiment that uses magnetic levitation to monitor the progress and determine the activation energy of a condensation reaction on a polymeric solid support. The method employs a cuvette filled with a paramagnetic solution positioned between two strong magnets. The…
