I’ve been rereading Steven Pinker’s Enlightenment Now. I am familiar with criticism of his work, but I am a fan nonetheless—maybe it comes from the fact that I believe we can read works even if we dispute some of the points and still find them worthy. In his chapter on “Knowledge” Pinker writes: “So much Read More
Artificial intelligence is rapidly becoming a quiet partner in the work teachers do every day. While much of the conversation focuses on collaborative, whole‑school adoption, the reality is that many educators are using AI individually—experimenting on their own, testing tools privately, and integrating them into their workflow long before formal policies or training appear. In Read More
In my work, I see lots of examples of people accepting what comes from AI as true; we accept whatever it gives us with little effort to confirm it. We should be concerned about this, except for the fact that humans have a very long history of accepting information as correct from sources without any Read More
A post for students in network security class: ARP spoofing is a powerful technique used by hackers to intercept and view unencrypted web traffic on a local area network (LAN). This attack exploits a fundamental vulnerability in the Address Resolution Protocol (ARP), which the internet uses to map a device’s IP address (where it is Read More
A blog post for students network security class: Deepfakes represent a modern frontier of digital deception, consisting of counterfeit images, videos, or sounds generated through machine learning algorithms. While these tools can be used for entertainment, they are increasingly weaponized by hackers as social engineering techniques to psychologically influence human behavior. By using technology to Read More
Many high schools, including vocational or trade high schools, offer a range of computer science, digital media, or business applications courses. The specifics of these offerings depend on the history and popularity of the department and the nature of the local business community. If an art teacher is hired who has special skill in digital photography, for example, the school may offer a Read More
159: Multimedia in Schools Generations of students have created presentations using a series of programs that combine text, images, audio, and video (thus the “multi” in multimedia). Many trace the beginnings of this type of educational software to HyperCard and HyperStudio, programs that available were for Apple computers marketed in schools in the early 1990’s. Interest in multimedia grew when video cards, color displays, audio Read More
180: On Multiple Working Hypotheses When I was an undergraduate student studying biology, a botany professor shared with us an article from Science magazine published in 1890. The paper was presented to the Society of Western Naturalists by its president T. C. Chamberlin. It was very influential to me in 1985, but during a move Read More
161: A Story About School IT Leaders I once coached a technology coordinator who was fond of saying, “I built what they asked for, it they asked for the wrong thing, that is not my problem.” He used it whenever the educators decided the system they wanted wasn’t exactly what they wanted and they asked him to Read More
When I was a student, I was not a strong math student; my lowest grades were always earned in math class. I attributed this to the “D” I earned in math when I was in 4th grade. Despite this, I became a math teacher. My students (and their parents) frequently said I was among the best math teachers they ever had. I attribute this to Read More
