In general, humans like to categorize using dichotomies; an object is placed in one group or another.

Curriculum Repositories Defined
Teachers’ capacity to use technology in classrooms is also improved by the easy availability of technology-based activities and lessons that are aligned with their curriculum needs.

Two trends are differentiating the s-curve describing the evolution of ICT in the 21st century form Read More
Colour Contrast Analyzer: A Tool for ADA Compliance
This video introduces a tool that can be used to check that your files have sufficient color contrast that those with certain visual impairments can view the text and images.
Pedagogical Nihilism: An Idea Worth Exploring
One of the first steps I took as an undergraduate student to become in independent intellectual—which I define as taking an active role in defining the course of one’s own learning—was to begin reading essays by scientists. At the time, there were Lewis Thomas and Stephen Jay Gould who were regular contributors. It was a Read More

If students–all students–cannot see or hear the materials teachers create, then the are “inaccessible.” One of the steps educators should take to make their files and pages accessible to those who have vision disabilities is to make sure files have sufficient color contrast.
