As worldwide energy shortages and environmental degradation increase, along with steady increases in population, current science and technology are confronted with many challenges to successfully sustain our society. Among the existing promising choices, photocatalysis has been widely considered as a potential solution to energy and environment…

The history of general chemistry is one of almost constant calls for reform, yet over the past 60 years little of substance has changed. Those reforms that have been implemented are almost entirely concerned with how the course is taught, rather than what is to be learned. Here we briefly discuss the history of the general chemistry curriculum and…

A rubric that embodies the key features of the process-oriented, guided-inquiry learning (POGIL) model was subjected to systematic study of validity and reliability. Nearly 60 college instructors used the rubric to evaluate four intentionally modified versions of an established POGIL activity. The modifications strengthened or weakened key…

Mapping methods employed by geographers, known as diffusion cartograms (diffusion-based density-equalizing maps), are used to present visually interesting and informative plots for data such as income, health, voting patterns, and resource availability. The algorithm involves changing the sizes of geographic regions such as countries or provinces…

An overview and simple example of photoelectron imaging is presented, highlighting its efficacy as a pedagogical tool for visualizing quantum phenomena. Specifically, photoelectron imaging of H[superscript -] (the simplest negative ion) is used to demonstrate several quantum mechanical principles. This example could be incorporated into an…

Printers capable of producing three-dimensional objects are becoming more common. Most of these printers are impractical for use in the chemistry classroom because of the expense incurred in fabricating a print head that must be controlled in three dimensions. We propose a simpler solution to this problem that allows the emerging technology of…

Students of organic chemistry traditionally make 3 x 5 in. flash cards to assist learning nomenclature, structures, and reactions. Advances in educational technology have enabled flash cards to be viewed on computers, offering an endless array of drilling and feedback for students. The current generation of students is less inclined to use…

This article summarizes the findings of a survey study of undergraduate research (UR) students presenting their research at the fall 2007 and fall 2008 American Chemical Society (ACS) National Meetings. The purpose of the study is to probe the perceived benefits of conference participation to UR students. Results suggest that participation in…

This paper describes two techniques for rendering visual concepts encountered in an organic chemistry course into tactile representations for students who have low vision. The techniques--which utilize commercially available products--facilitate communication of organic chemistry between student and instructor. (Contains 1 figure, 2 tables and 1…

The Reaction-Map of Organic Chemistry lists all the most commonly studied reactions in organic chemistry on one page. The discussed Reaction-Map will act as another learning aide for the students, making the study of organic chemistry much easier.

Common examples of graphic organizers include flow diagrams, concept maps, and decision trees. The author has created a novel type of graphic organizer called a decision map. A decision map is a directional heuristic that helps learners solve problems within a generic framework. It incorporates questions that the user must answer and contains…

There is a misconception among undergraduate students that global warming is caused by holes in the ozone layer. In this study, we evaluated the presence of this and other misconceptions surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and the ozone hole in students' conceptual frameworks. We…

The students are now given pre-screened articles related to the classroom topic, which demonstrates the relevance of scientific literature to them. The approach helps in strengthening the reading and writing skills of the students.

A number of chemical concepts can be easily illustrated in a more friendly way to children by using toys as teaching tools in the classroom. Some of the examples illustrated are shrinking toys, drinking birds and hand boiler.

The story to improve student enthusiasm for writing reports about the chemistry behind events reported in the news and movies were chosen as the source material. The use of movies in the chemical classroom helps an instructor move the subject of chemistry from abstract, general themes to the personal and subjective arena of human interactions.
