JCE 90.11—November 2013 Issue Highlights

Ninety Years New

The November 2013 issue of the Journal of Chemical Education is now available . This latest issue of JCE plus the content of all past issues, volumes 1 through 90, are available at .

Cover: Observations and Demonstrations

Six substances are shown on the cover at their melting points, with a frozen solid phase partially present in the liquid phase. Of the six systems, only solid water has a lower density than its liquid. In the article , Steven Murov discusses the liquid−solid density relationship of the water−ice system as an example of an often-overlooked observation. In addition to providing an experience that shows the anomalous behavior of water, this demonstration helps emphasize for students the importance of making careful, complete, and unbiased observations. Murov also presents a .

Editorial: Energy in the Age of Sustainability

As a continuation to the October issue’s examination of , Héctor D. Abruña discusses how meeting global energy needs in a sustainable and environmentally responsible way is one of the .

Safety

In , William Tolman and co-authors describe an effective way of addressing the need for an improved culture of safety in research-intensive science departments.

Massive Open Online Courses in Chemistry (MOOCs)

Two articles in this issue continue the dialog started in the March 2013 editorial, See a letter from Liberato Cardellini on as well as a technology report on 
by Alexey Leontyev and Dmitry Baranov.

Chemical Education Research

As discussed by Vicente Talanquer in , anthropomorphizing atoms and molecules and building explanations in terms of wants or needs (teleological explanations) can be useful pedagogical strategies for facilitating student understanding of abstract chemical models about the structure and properties of matter at the submicroscopic level. Nevertheless, teleological explanations generate an illusion of understanding that may hinder learning in the longer term.

In , Kevin M. Esterling and Ludwig Bartels present an evaluation of the impact of an atoms-first curriculum on student success in introductory chemistry classes.
