A speaker is a device that converts an electronic signal into sound. The speaker you will build (see figure 1) consists of a Styrofoam or paper cup, a coil of wire, a permanent magnet, and a signal source. The electronic signal goes through the coil and creates a varying electromagnet. The attraction and repulsion between the electromagnet and the permanent magnet cause the cup to vibrate and produce sound.

One idea brought up by several speakers this year is a hybrid grades-free way of evaluating students. In each case, it included a high-bar pass/fail approach to class assignments, with a final, more regular grade for the entire semester. One of the speakers who presented what he called a “Not Yet” grade was “digital ethnographer” Michael Wesch, a professor at Kansas State University. That’s his photo at the top. He told the crowd that they had to inspire “wonder” in their students in order to get them to learn as much as possible. Some key quotes from him: “Low standards/high stakes are the opposite of what you want.”

Keynote speaker George Couros is a what’s called a “division principal” back home in Canada. He’s a blogger and author who is all about encouraging creativity and change in public education with an emphasis on taking advantage of digital tools. He told the conference that that it’s foolish to deny students use of their smartphones and other digital tools in the classroom — and even on exams. In 2015, being able to figure out what information is relevant is more important than memorization when most facts are a click away, he said.

There is no legal definition of "hate speech" under U.S. law, just as there is no legal definition for evil ideas, rudeness, unpatriotic speech, or any other kind of speech that people might condemn. Generally, however, hate speech is any form of expression through which speakers intend to vilify, humiliate, or incite hatred against a group or a class of persons on the basis of race, religion, skin color sexual identity, gender identity, ethnicity, disability, or national origin. 1 In the United States, hate speech is protected by the First Amendment. Courts extend this protection on the grounds that the First Amendment requires the government to strictly protect robust debate on matters of public concern even when such debate devolves into distasteful, offensive, or hateful speech that causes others to feel grief, anger, or fear. (The Supreme Court's decision in Snyder v. Phelps provides an example of this legal reasoning.) Under current First Amendment jurisprudence, hate speech can only be criminalized when it directly incites imminent criminal activity or consists of specific threats of violence targeted against a person or group. Hate Crime For the purposes of collecting statistics, the FBI has defined a hate crime as a “criminal offense against a person or property motivated in whole or in part by an offender’s bias against a race, religion, disability, sexual orientation, ethnicity, gender, or gender identity,” including skin color and national origin.  Hate crimes are overt acts that can include acts of violence against persons or property, violation or deprivation of civil rights, certain "true threats," or acts of intimidation, or conspiracy to commit these crimes. The Supreme Court has upheld laws that either criminalize these acts or impose a harsher punishment when it can be proven that the defendant targeted the victim because of the victim's race, ethnicity, identity, or beliefs.  A hate crime is more than than offensive speech or conduct; it is specific criminal behavior that ranges from property crimes like vandalism and arson to acts of intimidation, assault, and murder.  Victims of hate crimes can include institutions, religious organizations and government entities as well as individuals.

There are keynote speakers—often the people who created the technology at hand or crafted a given language. There are the regular speakers, often paid not at all or in airfare, who present some idea or technique or approach. Then there are the panels, where a group of people are lined up in a row and forced into some semblance of interaction while the audience checks its e-mail.

Fewer than a fifth of undergraduate degrees in computer science awarded in 2012 went to women, according to the National Center for Women & Information Technology

The average programmer is moderately diligent, capable of basic mathematics, has a working knowledge of one or more programming languages, and can communicate what he or she is doing to management and his or her peers

It typically takes a group of people to organize the event. They come up with a common theme of what they want the Edcamp to focus on and then they invite educators from around the school, district or state to attend and present. Attendees do not all have to present but some Edcamps encourage it.

Edcamps are about building an educational community and sharing best practices. Camps are known for bring diverse people together for a common good and Edcamps have the same goal in mind.
