In science, we make our living as it were by measuring. As a human activity, measurement involvessome errors. When a making measurements, there are (usually) three potential sources of error: The person who is making the measurement could make a mistake. The same person who measures the same thing more than once is likely to Read More
I recently found my summary of an article that appeared in Scientific American in 2010 in which Tim Berners-Lee looks back at the world wide web 20 years after it was invented. The issues seem as relevant today as then. Universality– Because all content is based on the same protocols (hyper text markup language at Read More
I recently discovered some materials I uploaded to MERLOT had been orphaned after I moved my web site over a year ago. I have uploaded links to: Online Course Development Embed a Twitter Timeline in Your Virtual Classroom Introduction to Derivatives for Physics Students
A fictional story based on true events: Mrs. Smith was hired as a principal in a school enrolling student in grades 5-8. She started a Facebook group for the school and encouraged parents to join in it. The principal’s time on the job was contentious and, in many cases, drama arising from the Facebook group Read More

New infrastructure was added to buildings, new personnel had to Read More
In manufacturing, the expected performance of the product is well-defined; we know how to measure performance and our methods can usually be tested. We build prototype systems, compare the outcomes with the standards, then discard those systems that don’t work. The prototyping and testing can be done in highly-controlled circumstances as well. Further, manufacturers who Read More
Teacher burnout is something we hear about frequently in the time since the pandemic. The problem appears to be worse than it ever has, and teachers are leaving the profession as a result. Educators are focusing on teacher burnout on social media as well. For example, this tweet: prompted my reply: I was challenged to Read More
In reality, lesson planning is one of the least certain tasks an educator undertakes. The lesson planner can be sure of what they intend to teach; it may even be articulated in measurable learning outcomes (the value of which is dubious). The teacher also believes they know how to present the material so that students Read More
One of the discoveries of the cognitive and learning sciences with the greatest implications for teaching is that students cannot learn passively. While lecture, readings, and similar tasks do still have a role in classrooms, effective teachers include a range of task that lead to active cognitive engagement. These tend to find students discussing, asking Read More
