http://www.oercommons.orgOER Commons is the first comprehensive open learning network where teachers and professors (from pre-K to graduate school) can access their colleagues’ course materials, share their own, and collaborate on affecting today’s classrooms.enenhttp://www.oercommons.org/courses/windmill-galleryThis collection of still images features a variety of windmills and turbines.http://www.oercommons.org/courses/windmill-galleryhttp://www.oercommons.org/courses/what-childrens-perspectives-tell-us-about-inclusionThe underlying premise of this unit is that we are all experts in different ways, and that our different experiences and understandings are of value. Inclusive education is presented and discussed as under construction, both in educational settings and as a concept. The materials to be found in this unit are largely rooted in the social model of disability and human/disability rights frameworks.http://www.oercommons.org/courses/what-childrens-perspectives-tell-us-about-inclusionhttp://www.oercommons.org/courses/what-causes-the-gulf-streamThis video segment adapted from NOVA visualizes how Earth's rotation and uneven heating from the Sun cause prevailing winds and influence ocean surface currents. An animation and infrared satellite image illustrate the shape and direction of the Gulf Stream System in the Atlantic Ocean.http://www.oercommons.org/courses/what-causes-the-gulf-streamhttp://www.oercommons.org/courses/what-are-statisticsThis module describes the various ways the term "statistics" is used.http://www.oercommons.org/courses/what-are-statisticshttp://www.oercommons.org/courses/water-what-ifs-water-quality-and-dissolved-oxygenThis Science Junction website features general information and three lesson plans about dissolved oxygen geared toward middle and high school students. Lessons cover topics such as what dissolved oxygen is, why it is important, and how decomposition of organic material affects dissolved oxygen. The third lesson includes an activity in which students are instructed to design an experiment to test effects of changes in dissolved oxygen concentration. The lessons meet several National Science Education Standards, Delaware science standards, and North Carolina competency goals.http://www.oercommons.org/courses/water-what-ifs-water-quality-and-dissolved-oxygenhttp://www.oercommons.org/courses/water-water-everywhereThis is a good beginning of the year lesson to review fractions, decimals, geometry (the number of degrees in a circle and drawing a circle with a protractor), graphing, and metric measurement. This lesson is a good way for students to meet their peers while working cooperatively in a task-oriented group. The watermelon you will be using for the activity is also a good start-of-the-year treat. Be sure to get an extra watermelon or two to share at the end of the activity.http://www.oercommons.org/courses/water-water-everywherehttp://www.oercommons.org/courses/war-memorials-and-commemorationThis unit gives you the opportunity to practise good study techniques using the theme of commemoration and memorials. It will help you to begin to think about how form influences meaning in the arts and how ideas influence approaches to the humanities.http://www.oercommons.org/courses/war-memorials-and-commemorationhttp://www.oercommons.org/libraries/war-is-a-blessing-not-a-curse-the-case-for-why-we-must-fightIn 1917, voices were raised outside Congress on both sides of the issue of American involvement in the European war. Shortly before President Woodrow Wilson's call for war on April 2, 1917, the editors of a conservative magazine, the North American Review , laid out the basic arguments for U.S. participation. Fundamentally, they saw the war as a struggle between democracy and barbarism. Similar statements and speeches--as well as more coercive measures--gradually captured the public discourse. Fairly quickly, those who rejected the rationales for United States participation in the war found themselves increasingly isolated. Liberals, intellectuals, and even many socialists soon lined up behind American intervention.http://www.oercommons.org/libraries/war-is-a-blessing-not-a-curse-the-case-for-why-we-must-fighthttp://www.oercommons.org/courses/timed-temperature-viTo read a temperature once every second for one minute.http://www.oercommons.org/courses/timed-temperature-vihttp://www.oercommons.org/courses/the-washington-monument-tribute-in-stonefocuses on George Washington's life, his impact on our nation, and the design and history of this famous memorial.

Known as Black Codes, these laws sought to recreate slavery in all but name by preventing blacks from working outside of agriculture and domestic service, limiting their movement, and subjecting those without a contract for employment to arrest and forced labor. Local officials also gave tacit or overt support to intense racist violence. Rioting whites in Memphis killed forty-six African-Americans in May 1866. Two months later, thirty-four blacks and three white supporters were murdered by a white mob in New Orleans. In this picture, Thomas Nast gave his view of Andrew Johnson's role in the July 1866 New Orleans riot.http://www.oercommons.org/libraries/the-massacre-at-new-orleanshttp://www.oercommons.org/matters/the-instructional-use-of-learning-objectsThis is the online version of The Instructional Use of Learning Objects, a new book that tries to go beyond the technological hype and connect learning objects to instruction and learning.
