The use of "Origami" is presented as an accessible and transferable modeling system through which to convey the intricacies of molecular shape and highlight structure-function relationships. The implementation of origami has been found to be a versatile alternative to conventional ball-and-stick models, possessing the key advantages of being both…

An inexpensive and equipment free approach to teaching the technical aspects of DNA sequencing. The activity described requires an instructor with a familiarity of DNA sequencing technology but provides a straight forward method of teaching the technical aspects of sequencing in the absence of expensive sequencing equipment. The final sequence…

What are the typical printing behaviors of students? What is the extent of wastage? What are student attitudes towards different pay-per-print schemes? What might be strategies for educational institutions to achieve less printing while not impeding pedagogical quality?

To deter cheating, teachers commonly use exams printed on differently colored paper or with varied question orders. Previous studies, however, reported that paper color and question order affect exam performance and suggested that teachers should adjust students' scores accordingly and discontinue the use of alternate exam forms. We conducted 2…

The acid-catalyzed hydrolysis of cellulose accounts for the deterioration of paper in library books and other written records. To combat this threat to our written heritage, new permanent papers have been developed that are relatively chemically stable and undergo a very slow rate of deterioration. Many of these new papers are manufactured from…

Reams of paper come in a standardised system of related sheet sizes. Most people are familiar with the international paper sizes A4, A3 and B4, but there are others. The ratio of the sides of any sheet in the series is such that if the paper is cut or folded in half on itself then the ratio of the sides remains unchanged. Due to this property of…

This study was designed to examine the effects of tracing and fading prompts to improve the handwriting of two preschoolers both diagnosed as Developmentally Delayed (DD) and one of whom had fine motor goals.

For the very first time this in-depth paper studies the archives of the historic Paolo Pigna Paper Mill in Alzano Lombardo (Bergamo, Italy), which played a leading role in Italian history and culture: so much so that it ended up with fusing its own image to the very market where it operated, that is, the Italian schools. After being taken over by…

In this article, the author presents a paper folding activity that can be used for teaching fractions. This activity can be used to describe areas of folded polygons in terms of a standard unit of measure. A paper folding fractions worksheet and its corresponding solutions are also presented in this article. (Contains 2 figures.)

The authors review commentaries by J. E. Broderick and A. A. Stone (2006); H. Tennen, G. Affleck, J. C. Coyne, R. J. Larsen, and A. DeLongis (2006); and M. K. T. Takarangi, M. Garry, and E. F. Loftus (2006) on their original article (A. S. Green, E. Rafaeli, N. Bolger, P. Shrout, & H. T. Reis, 2006). The authors were pleased to find more agreement…

To circumvent the problem of academic dishonesty through the mass administration of multiple-choice exams in college classrooms, a study was conducted from 2003 to 2005, in which multiple versions of the same examination were color coded during testing in a large-enrollment classroom. Instructors reported that this color-coded exam system appeared…

Our study compared the quantitative and qualitative outcomes associated with course evaluations collected over the Internet with those collected using a paper-and-pencil method. We randomly assigned students to 1 of the 2 different formats. There was no significant difference in quantitative student responses based on administration method, but…
