Three undergraduate students functioned as teaching assistants in unit ops lab for their senior project, which included developing a purchased size exclusion chromatography experiment, supervising the running of this experiment, and assisting the junior students with their calculations. They also read the reports, graded them, and commented on…

There are many wonderful experiences and resources from which to create innovative and dynamic works of art. It is important to remember that students don't always have these skills and experiences. It is up to the teacher to provide in-depth prompts to inspire their students to master their technique, as well as the unique storytelling skills a…

It can be challenging to know which accommodations for special learners can be used within the various secondary general music class settings. Fortunately, there have been several recent music education and therapy articles based on special education practices that have addressed techniques for working with students with special needs in music.…

As a university-based art educator inspired by the efforts of environmental artists, the author has been working to share their achievements with students and teachers through eco-art education. She aims to continue this work through this article by sharing recent developments in this emerging field of inquiry. In hopes of encouraging art…

Body painting as a tool for teaching anatomy is becoming increasingly popular as it is fun and diffuses the formal academic context. Students claim bright color plays a significant role in retention of knowledge from painting sessions. Medical students (n = 117) were divided into two conditions: block color (CLR) and black outlines (BLK). Students…

A quasi-experimental action research with a pretest-posttest same subject design was implemented to determine if there is a different effect of the flash card method and the multisensory approach on kindergarteners' achievement in sight word recognition, and which method is more effective if there is any difference. Instrumentation for pretest and…

The authors used a withdrawal design to evaluate the effects of a modified Color Wheel System (M-CWS) on the on-task behavior of 7 students enrolled in the 4th grade. Standard CWS procedures were modified to include a 4th set of rules designed to set behavioral expectation for cooperative learning activities. Mean data showed that immediately…

Conceptually, students are typically introduced to light as a type of wave. However, children struggle to understand this model because it is highly abstract. Light can be represented more concretely using the photon model. According to this scientific model, light emanates from sources as tiny "packets" of energy (called "photons") that move in…

It is instructive and interesting to find hidden numbers by using different positional numeration systems. Most of the present guessing techniques use the binary system expressed as less-than, greater-than or present-absent type information. This article describes how, by employing four cards having integers 1-64 written in different colours, one…

Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

An activity has been designed for the purpose of teaching how light is dispersed in a straight line and about the interaction between matter and light as well as the related concepts of shadows, partial shadows, reflection, refraction, primary colours and complementary (secondary) colours, and differentiating the relationship between colours, all…

English teachers have a unique opportunity to expand and develop the way their students think. Too often, students are comfortable in thinking about reading and writing processes in a concrete or linear way. They are used to "right" or "wrong" answers in their other studies and look for the same in their English assignments. While teachers often…

The different combinations involved in additive and subtractive colour mixing can often be difficult for students to remember. Using transmission graphs for filters of the primary colours and a numerical scheme to write out the relationships are good exercises in analytical thinking that can help students recall the combinations rather than just…

This study uses history of science in teaching natural sciences from the early grades. The theoretical framework used is Cultural Historical Activity Theory (CHAT), which is a theory with expanding applications in different fields of science. The didactical scenario, in which history of science is used in a CHAT context, refers to Newton's…

A handheld digital microscope (HDM) interfaced to a computer with a presentation projector is used to project an out-of-focus yellow patch on the screen, then the patch is brought into focus to show that, paradoxically, there are red and green but no yellow pixels. Chromaticity diagrams are used to discuss this observation and spectroscopic…
