STEM is about the integration of science, technology, engineering and mathematics. To teach STEM effectively, students need practical examples of subject integration. A good example is the use of an electron microscope in teaching physics and biology. An electron microscope is an instrument in which the operation depends on electromagnetism and…

An important aspect of science education involves helping students learn to read and communicate scientific information and arguments. In this note, I would like to share a resource that I have come across which I have found to be a useful tool for helping students improve those skills, learn content material, and acquaint them with a great…

In the last decade many studies have stated that learning based on digital games emerges as an effective way to combine teaching and learning processes with the attractiveness of digital technologies, because they are dynamic and playful. However, the vast majority of these digital resources -- such as educational games -- are still essentially…

In this article I describe an art-based procedure with a gradual sequence of drawing tasks that guides an art therapy client through graphic stages from point, to line, to plane. The client begins by making random dots, connecting them one to another with an unbroken line that reaches all the dots, perceiving abstract or figurative imagery in the…

The combined lab and lecture course is designed around the themes of colorants (dyestuffs and pigments) and fibers (natural and human-made) for nonscience majors. Students dye natural and synthetic fibers with natural dyes such as turmeric, raspberries, tea, and cochineal insects as well as synthetic dyes. The students observe the colorfast…

A week after the 9/11 WTC event, the collage project that Nell Ruby and her class had been working on in a basic design classroom lacked relevance. They had been working from master works, analyzing hue and value relationships, color schemes, shape, and composition. The master works seemed unimportant because of the immense emotional impact of the…

This paper describes an easy experiment to study the absorption and action spectrum of photosynthesis, as well as the inhibition by heat, high light intensity and the presence of the herbicide 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) on the photosynthetic process. The method involves measuring the chlorophyll fluorescence emitted by intact…

In this article the effect of light quality on the size of the photosystem II (PSII) light harvesting complex (LHCII) is studied by measuring the chlorophyll fluorescence emitted by leaf sections of oat ("Avena sativa," var. Prevision) plants previously treated with either white light or with light filtered through blue, green, red or farred…

Many counting problems can be modeled as "colorings" and solved by considering symmetries and Polya's cycle index polynomial. This paper presents a "Maple 7" program link http://users.tamuk.edu/kfdrc00/ that, given Polya's cycle index polynomial, determines all possible associated colorings and their partitioning into equivalence classes. These…

This paper examines the benefits of a metaphorical graphical user interface (GUI) and discusses how metaphorical interfaces can be used to deliver instruction on stress management. A computer-based instructional (CBI) program for college students was developed on the fundamentals of stress and the role of time management as a coping strategy. The…
