"Today, it's in vogue to talk about how Slack is going to replace email. As someone who has seen this play out a dozen times now, let me give you a little spoiler: Slack is not going to replace email. But Slack isn't the problem here, either. It's just another communication tool. The problem of email overload is both ancient and persistent. If the problem were really with "email", then, presumably, one of the nine million email apps that dot the app-stores like mushrooms sprouting from a globe-spanning mycelium would have just solved it by now, and we could all move on with our lives. Instead, it is permanently in vogue1 to talk about how overloaded we all are. "

"Students presented their work. They had about 30 seconds. A few students served as a panel (if we're sticking with "Shark Tank", these are your Mark Cubans, your Mr. Wonderfuls, etc.). The teacher had prepared a few scripted questions, which the panel asked psuedo-randomly. The presenters knew these questions ahead of time and had to be prepared to answer them. Students responded to the questions that were selected. The panelists convened with their groupmates to discuss the presenters' responses and to develop deeper, more probing questions. The presenters also had a couple minutes to regroup and confer. After convening, the panelists return to their station and ask the questions that they and their group came up with. The presenters respond. From this point, it becomes semi-conversational as all the panelists are interested in getting their question answered.he presenters then answered those questions, which were generally more specific in nature and based on the initial responses of the presenters."

"Harry: "I just can't say "Find an avenue" because he's gonna say "you're not teaching me anything!" Bill: "Well, maybe that's the way to teach though. Maybe if you say "you must find an avenue. Next week, I'll show you an avenue, but this week, find an avenue!""

"These constructive quotes communicate that mistakes are desirable, which is a positive message and part of what we want students to learn. An appreciation of mistakes helps us overcome our fear of making them, enabling us to take risks. But we also want students to understand what kinds of mistakes are most useful and how to most learn from them. "

"My premise is that we're all sympathetic towards students who dislike mathematics, this course they're forced to take. We all have answers to the question, "What does it take to interest students in mathematics?" Though those answers are often implicit and unspoken, they're powerful. They determine the experiences students have in our classes. I lay out three of the most common answers I hear from teachers, principals, policymakers, publishers, etc., two of which are "make math real world" and "make math relevant." I offer evidence that those answers are incomplete and unreliable. Then I dive into research from Willingham, Kasmer, Roger & David Johnson, Mayer, et al., presenting stronger strategies for creating interest in mathematics education. "

"Why wipe the slate clean? Why erase such knowledge? Why not use it as a foundation to build upon?"

"At rOpenSci we are creating packages that allow access to data repositories through the R statistical programming environment that is already a familiar part of the workflow of many scientists. Our tools not only facilitate drawing data into an environment where it can readily be manipulated, but also one in which those analyses and methods can be easily shared, replicated, and extended by other researchers."

"Yet on the level of thinking of our Silicon Valley overlords, aspects of my cognitive abilities that are absolutely central to my educational success are taken to have literally no value at all. In educational research, perhaps the greatest danger lies in thinking "that which I cannot measure is not real." The disruption fetishists have amplified this danger, now evincing the attitude "teaching that cannot be said to lead to the immediate acquisition of rote, mechanical skills has no value." But absolutely every aspect of my educational journey - as a student, as a teacher, and as a researcher - demonstrates the folly of this approach to learning." True I think but echoed to greater and lesser extend by the educational system which helped create those who run Silicon Valley. h/t Dan Meyer

I wonder how often this opportunity is there but the person isn't . . . seems like the very definition of computational thinking. "In the end, the tool was very crude but accomplished something very useful: It had a flow that ensured all the reports required by people on the ground, and above, were sent in a timely and orderly manner. Each step of that flow was almost entirely automated. Each button filled a template and put the text in the clipboard for copy-pasting in the chat. Events were timed automatically. Distances and time of travel were computed automatically. A dropdown menu facilitated entering common values. Big warning signs were visible when a time critical step was ongoing, or some important data was missing."

""Indifference towards people and the reality in which they live is actually the one and only cardinal sin in design." This implies, for one, that good documentation does not excuse bad design. You can ask people to RTFM, but it is folly to assume they have read everything and memorized every detail. The clarity of examples, and the software's decipherability and debuggability in the real world, are likely far more important. Form must communicate function."
