Now we just need to determine whether our intersection point is inside or outside the triangle.

Let's put everything together. Get ready for a really powerful formula: the binomial coefficient (warning: you may need to watch this a few times!).

Time to get a little mathy. Let's look at the general form for any transformation.

Students work in groups to examine excerpts from primary source documents. They identify social and economic factors affecting specific categories of people when the Great Migration accelerated in 1916 to 1917: black migrant workers from the South, southern planters, southern small-farm farmers, northern industrialists, agents, and white immigrant workers in the North. Each student group creates a "perspectives page" to post for a gallery walk where students analyze the causes of the Great Migration and the changes it brought to both the North and South. Students also discuss the specific economic factors that influenced the Great Migration: scarcity, supply, demand, surplus, shortage, and opportunity cost. Using the PACED decisionmaking model, they analyze the alternatives and criteria of potential migrants.

On completion of this unit participants should:

Investigate and source digital versions of the Zambian curricula documents.
Determine what role for ICT has been envisaged by the national education authority as expressed within the official curriculum
Identify sixteen 21st century skills as defined by the World Economic Forum
Integrate at least two 21st century skills into their teaching and learning.

This animation seeks to lead students to a deeper understanding of the challenges that come with online learning for those with disabilities, and a newfound or renewed sense of empathy towards others.

This presentation introduces Computer Science students to the notion of accessibility: developing software for people with disabilities. This lesson provides a discussion of why accessibility is important (including the legal, societal and ethical benefits) as well as an overview of different types of impairments (visual, auditory, motor, neurological/cognitive) and how developers can make their software accessible to users with those disabilities. This lesson includes videos and links to readings and tutorials for students.

Suggestions of links to alternative activities for the teaching of the mathematical content represented in the activities.

This short video is an excerpt from the longer video Acid Test: The Global Challenge of Ocean Acidification, produced by the National Resources Defense Council (NRDC). This short version summarizes the science of ocean acidification as well as the social implications.

The United States has a long history of activists seeking social, political, economic, and other changes to America—along with a history of other activists trying to prevent such changes. American activism covered a wide range of causes and utilized many different forms of activism. American sociopolitical activism became especially prominent during the period of societal upheaval which began during the 1950s. The African American civil rights movement led the way, soon followed by a substantial anti-war movement opposing American involvement in the Vietnam War, and later by vigorous activism involving women’s issues, gay rights, and other causes. The United States remains a land of nearly constant change, and activists play a significant role in the ongoing evolution of American democracy. It seems likely that Americans will remain enthusiastic activists in the future. This exhibition is part of the Digital Library of Georgia.
