Measuring Worth – Relative Worth Calculators and Data Sets
“There two missions of this site. The first is to make available to the public the highest quality and most reliable historical data on important economic aggregates, with particular emphasis on “nominal (current-price) measures, as well as real (constant-price) measures. The second is to provide carefully designed calculators (using these data) that explain the many issues involved in making value comparison over time.
The data have been created using the highest standards of the fields of economics and history, and they are rigorously refereed by the most distinguished researchers in the fields. Beginning with the United States and United Kingdom and following with Australia, Japan and China, we will continue to add series from other countries using the same high standard.
The emphasis on nominal measures distinguishes this site. This attention is important because to comprehend a past transaction or asset, one must begin with the contemporary value of the item. To make this valuation meaningful, it must be measured against the value of the appropriate economic indicator in that year. To understand the valuation from another year’s perspective, one must carry that measure forward against the changing value of the indicator.”
What happens when 5th graders run the classroom: A SOLE in action | TED Blog
“Eleven-year-olds running a classroom? That could sound outlandish to some elementary school teachers, but not to Joe Jamison, or “Mr. J” as he is affectionately called by his fifth-grade students at Lawrence Intermediate School in central New Jersey.
“There is a feeling of excitement in the small classroom, decorated with inspirational quotes and bright educational paraphernalia. The kids sit at the edge of their seats, waiting in anticipation; they are eager to show their findings after spending an hour researching and putting together a presentation about a quote that Mr. J projected on a whiteboard at the front of the classroom: “The rights of the individual should be the primary object of all governments.” In groups, they were asked to figure out the significance of the quote, using only their critical faculties and a few laptops.
This activity is part of Mr. J’s bi-weekly SOLE session, a freestyle learning period revolving around a topic, quote or question. SOLE, which stands for Self-Organized Learning Environment, is a concept drawn from 2013 TED Prize winner Sugata Mitra’s wish in which he offered up a new vision of education that combines the vast resources of the Internet with children’s innate sense of curiosity. The School in the Cloud, as he calls it, is a global experiment in self-organized learning. SOLEs let kids puzzle through big questions and ideas on their own, teaching each other in the process.”
