My career has approximately coincided with the history of personal computers in schools. I was an undergraduate student when “computer” meant a device that sat on a desktop and was turned on only after placing a diskette in the drive that loaded the only program that could be used during the session. The display was Read More
Technology literacy has been on my mind. My definition is inexact, but I can recognize it in people. You might be able to judge your own technology literacy by reflecting on how you react to new technology. For this post, I am going to ignore those who enthusiastically accept any new device. These folks are goo to Read More
“Data” has become the mantra of educators for more than a generation. In my observations of these folks, there seems to be little regard for the quality of our data or the ethics whereby it is collected. Forty years ago, the OECD published eight principles of data collection that still provide good guidance… as long Read More
Decision making is an interesting activity. Ostensibly, we want leaders who step up and take action. We seek decisive leaders who step up and “get something done.” The reality, however, is that we often find those who make the best decisions do nothing… at least initially. Obviously, there are emergency situations in which one must Read More
Being Data-Driven is Nothing to Brag About (c) 2016 Dr. Gary L. Ackerman “Data-driven” has been the mantra of educators for the last generation. This mantra captures the practice of using students’ performance on tests to make instructional decisions. This model can be criticized for several reasons including the dubious reliability and validity of tests, Read More
Is the network reliable and robust? Can all devices stay connected throughout a lesson? Can latency be induced with multiple simultaneous downloads? Are multiple SSID’s seamless? (Can I move around campus and keep my wifi connection?) Is data backed up regularly and reliably?
The pandemic has raised several issues with education at all levels. One of the most interesting to me has been the seeming disconnect between being “data-driven” and decisions related to keeping schools open. Clearly the decision to keep a school open for in-person instruction rather than relying on remote instruction is complicated. There are many Read More
Accounting is a technology that accompanied the creation of writing, and counting changed when “we” decided accurate records we needed. Whereas many cultures with primary orality do not differentiate numbers (many unwritten languages quantify using words for “one,” “two,” and “many”). Accounting necessitated accurate calculation of numbers including decimal places. The familiar base 10 and Read More
Education has broad and diverse goals in our society: free and appropriate education for all. Despite the connotation of “standard” education, most recognize that “one size fits all” education is not what most students need. That suggests we recognize contingencies in education, just as scientists recognize contingencies. Science has centuries of managing contingencies, so we Read More
For a generation, educators have claimed to be “data-driven.” Ostensibly, they seek to ground their decisions and policies in measurable observation, but their constructs are dubious, their measures invalid and unreliable, and their analysis sloppy. Data are selected to If the debate surrounding the Common Core is so dissimilar to science, the reasonable question becomes, Read More
