Bloom's Taxonomy addresses the different levels of learning that can be utilized, starting with lower level learning (knowledge, facts, etc) to creating and developing new ideas. For example, for a history project presentation using PowerPoint, a student could create a timeline to accomplish the first step, remember. The timeline would give simple facts to be learned and memorized, like "the Declaration of Independence was signed on the fourth of July, 1776" (it actually was approved by congress on this date and was probably signed on August 2nd, but for the purposes of this I'll use the commonly believed misconception). The next step, understanding, would give more explanation as to how and why these events happened. This would show that they, for example, understand that taxation without representation acted as large motivator for the continental congress to call for independence from the crown. Applying their knowledge via PowerPoint, they could show a list of sources they used for their presentations. To accomplish the steps of analyzing and evaluating, students could critique each other's presentations, asking questions and commenting on elements that weren't clear. And for create, they could use PowerPoint's design features to make a new constitution, complete with amendments they think should be added.
To stay up to date with technology I would use http://www.techradar.com/, a site that prides itself with keeping regular people up to date with the newest technology and the best prices. While the site might look a little unprofessional, it offers valuable information on what new technology is available and trending. Additionally, by looking at its section on purchasing, teachers can stay up to date with how affordable new technologies are.
