LEARNING LIKE A VIKING
EDUCAUSE has an interesting article on the future of higher education. Here is an excerpt: The basic model of higher education that exists today was created in the 11th century, operates on a 19th-century calendar, yet is supposed to prepare students for life in the 21st century. Far too often, students are the passive recipients of content delivered by experts who lecture, a practice used since the 11th century but increasingly inappropriate today. School calendars, created two centuries ago, apparently remain resistant to change. And schools that are supposed to prepare a generation to confront today's challenges far too often fail at that task: only 63.2 percent of students who began college in 2003 earned a bachelor's degree by 2009.

DO IT YOURSELF CHEMISTRY
A study in Colorado has found little difference in the learning of students in online or in-person introductory science courses. The study tracked community college students who took science courses online and in traditional classes, and who then went on to four-year universities in the state. Upon transferring, the students in the two groups performed equally well. Some science faculty members have expressed skepticism about the ability of online students in science, due to the lack of group laboratory opportunities, but the programs in Colorado work with companies to provide home kits so that online students can have a lab experience.

WHAT ARE YOU TESTING
Testing your students is an essential part of the process to determine if they are indeed learning anything. Constructing a test is a learned behavior that needs practice and can usually benefit from assistance. In fact, creating good tests has become such a valuable skill that it has grown into a career for some folks. The test researchers note that true/false tests are the least effective for assessing learning and determining if you are indeed teaching your students. True/false tests are typically easy and you need a large number of items for high reliability. In addition, your students have a 50-50 chance of guessing the right answer and it is difficult to discriminate between students that know the material and students who don't.

HIDDEN PUBLIC KNOWLEDGE
Samuel Arbesman, author of The Half-Life of Facts: Why Everything We Know Has an Expiration Date, writes that "since scientific knowledge is still growing by a factor of ten every 50 years, it should not be surprising that lots of facts people learned in school and universities have been overturned and are now out of date." Arbesman, a senior scholar at the Kaufmann Foundation and an expert in scientometrics, looks at how facts are made and remade in the modern world. And since fact-making is speeding up, he worries that most of us don’t keep up to date and base our decisions on facts we dimly remember from school and university classes that turn out to be wrong.
