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.

Social bookmarking. When you save a Web site as a favorite or bookmark, it's added to a list that stays within that browser. Use another computer, and you don't have access to that bookmark. When you use a social-bookmarking service, you save your bookmarks on that server, making them available to you wherever you access the Web, and allowing you to share them with others. Ask your students to create accounts on a social-bookmarking service and to bookmark Web sites, news articles, and other resources relevant to the course you're teaching. Create a unique "tag" for your course and have your students use it, so that their bookmarks can be easily found. Ask students to apply multiple tags to the resources they bookmark, as a way to help them locate their bookmarks quickly and to prepare them for the kind of keyword searching they'll need to do when using library databases. If you're teaching a face-to-face or hybrid class, be sure to spend some class time having students share their latest finds, so they can see the connections between this work outside class and classroom discussions. Students most likely won't find this difficult. After all, you're asking them to surf the Web and tag pages they like. That's something they do via Facebook every day. By having them share course-related content with their peers in the class, however, you'll tap into their desires to be part of your course's learning community. And you might be surprised by the resources they find and share.

reauthorization of the Higher Education Act might shake out.

More and different types of learning and teaching are available in the digital environment. We must convince ourselves that we don’t yet understand digital education so we may open the doors more broadly to innovation and creativity

Few institutions pay much attention to re-creating these spaces online

Here’s how it works, step by step: The transmitter chip is made of four hybrid silicon lasers. Light beams from the lasers each travel into an optical modulator. The modulator encodes data onto the beams at 12.5Gbps. The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors. The photo detectors convert data back into electrical signals.

There are better forums for discussion than online discussion forums. The discussion forum is a ubiquitous component of every learning management system and online learning platform from Blackboard to Moodle to Coursera.
