Ethical hackers are vital security professionals who understand how to attack infrastructure to discover vulnerabilities before bad actors can exploit them.

Learning is a dynamic, ongoing process that is simultaneously biological and cultural. It isn't just for children; people continue to adapt to their environments and experiences from before birth through the entire life span.

Prior knowledge is a double-edged sword: it can reduce the mental effort needed for new tasks and facilitate learning. However, it can also lead to bias, causing learners to ignore new info that doesn't fit their existing mental frameworks

Much of what we know about the science of learning comes from "WEIRD" populations (Western, Educated, Industrialized, Rich, Democratic). We need more diverse research to ensure our understanding of learning applies to all human beings

Physical exercise isn't just for the body; it is beneficial for learning and cognition. Consistent exercise training in children is associated with improvements in reading comprehension, executive function, and mathematical computation.

It is neurobiologically impossible to think deeply about information for which you have no emotion. Emotions are a ubiquitous dimension of thought that steer our behavior and tell us what is important to remember.

A growth mindset—believing that intelligence can be acquired through hard work—leads learners to adopt mastery goals. Conversely, a fixed mindset often causes people to prioritize "looking good" over the actual effort required to learn

Culture is not an external influence but a central aspect of being human that coordinates the biological systems involved in learning. All learning is a social process shaped by and infused with a system of cultural meaning.

Schools must be careful not to let "educational technology titans" exploit students for profit or use them to test new products. Technology should serve the educational good, not techno-corporate ideals. #StudentPrivacy #EdTechEthics

The role of school IT managers is evolving. Beyond technical support, their core responsibility is to ensure that technology integration is never achieved at the cost of a student’s privacy or long-term interests. #ITLeadership #Ethics

Managing student data is like entrusting a sensitive family heirloom to a high-tech vault; while you want the vault to be secure and functional, you must constantly audit the operators to ensure they aren't secretly using your treasure for their own profit.

True technology literacy isn’t just knowing which buttons to click on a single system. If a student can only use one type of computer, are they really literate?

The three pillars of network security are Confidentiality, Integrity, and Availability. For schools, confidentiality is particularly crucial due to legal requirements like FERPA that protect sensitive student data.

Over my career, I’ve been labeled, belittled, yelled at, and asked to scale back my lessons by principals, curriculum coordinators, superintendents. They never got what they wanted.

Good documentation of your network. including a logical map and device locations, is vital for troubleshooting and upgrades. Unfortunately, it is often neglected one school networks because IT professionals are overworked

Bandwidth is a zero-sum quantity. If students are streaming music or video, they are consuming resources that become unavailable for other educational tasks.

Don't be fooled by cheap home setups and the enterprise-grade networks are required for schools just because you set one up does not mean you can do the other.
