Information Age Education (IAE) is an Oregon not-for-profit corporation founded by David Moursund in August 2007. The IAE Blog was started in August 2010.

Rapid Changes in GMO Technology

The MIT Technology Review is on my regular “must read” list of magazines that I subscribe to. Every issue contains articles that challenge my current knowledge and insights into how the world is changing.

The first issue of 2018 is certainly no exception. Antonio Regalado’s article about gene editing, These Are Not Your Father’s GMOs, caught my attention (Regalado, January/February, 2018). In brief summary, gene editing that merely changes a gene without inserting “foreign matter” is legal in the United States. For example, it is legal to insert an extra copy of a small piece (a snippet) of a plant’s DNA strand into the DNA strand, or to remove a snippet. This can be done with current technology, and it is being done.

The Math Learning Center

I was one of the founders of the Math Learning Center (MLC) and have served on its Board of Directors since this 501(c)(3) organization started 40 years ago. During these 40 years, I have advocated for increased use of calculators and computers in math education. Several hundred of my math education and computer education publications are available free online (IAE, 2017). Three of my more widely read math education articles are (Moursund, 2017a; Moursund, 2017b; and Moursund, 2017c).

One of my contributions to the MLC was getting it started in developing some online Math Manipulatives programs (Moursund, 4/19/2013). A catalog of the MLC’s current collection of 11 free online math manipulatives is available (MLC, 2017).

Underwater Robotic Miners

Almost every day I find one or more science and technology articles that really catch my attention. David Hambling’s article about developing robots to do underwater mining certainly provides a good example (Hambling, 10/23/2017).

The problem that many mining operations face is that of water getting into a mine. The history of steam engines is intimately connected with this problem. Steam engines were first developed to pump water out of mines. Quoting from Encyclopedia.com (n.d.):

Larry Cuban

Larry Cuban is Professor Emeritus of Education at Stanford University. He was a high school social studies teacher (14 years), district superintendent (7 years), and university professor (20 years). He has published a very large number of op-ed pieces, scholarly articles, and books on classroom teaching, history of school reform, how policy gets translated into practice, and teacher and student use of technologies in K-12 and college.

Over the years, I have read many of Cuban’s articles. While I have not always agreed with what he was saying, I am always impressed by the quality of his thinking and clarity in expressing his ideas.

In Terms of Vacuum Tube Dollars, Likely You Are a Billionaire

Most days I spend quite a bit of time browsing educational and technical websites. Today, this led me to reading about the early history of transistor radios and transistors.

The transistor was invented in 1947. In many electronic circuits such as in a radio, a transistor could be used in place of a vacuum tube (Wikipedia, n.d.a). The transistor is smaller, much more rugged, has a much longer expected life, and uses much less electric power.
