This is for all teachers, but only some of you will be able to do this. Depends on your topic. This may pertain mostly to biology teachers, maybe stats or math, but by extension, any science or empirical topic including history.
Never mind that the first thing bio students to know is about Hydrogen bonds, or that the first thing stats students need to know is basic probability theory. You already probably do some sort of introduction thing that gets the students oriented to your subject, with a “get to know you” component, etc.
Replace that with this. The first thing the students should encounter in your classroom is some sort of topic appropriate, level and age appropriate, encounter with pandemic reality. Many of your students are not taking this pandemic seriously. They’ve been hanging round mask-less and in close quarters with their friends all summer, maybe practicing on a team, whatever. They are not going to properly manage their own viral shed or the possibility of someone else’s pathogenic effluence. They are going to be gobbing all over each other, their desks, and you.
Now is the time to use your mad teaching skills to push at least some of your students in the direction of being more careful, and possibly, slowing the spread of the Covid-19 causing disease.
I know, I know, you are saying “we are doing distance learning, this does not matter.” But it does matter. The back to school outbreak is going to happen whether or not you, or your school, is doing distance learning, and your small part of the learning community overlaps with the rest of it. And, you never know when your college, HS administration, or school district is going to send the students back into your room. This is your chance. Take it.
Can’t think of an example of a lesson that would smart up your students, to enhance the behavioral part of their innate immune system? Don’t give me that! Of course you can, you are a great teacher! In face, once you’ve thought about it, I want to hear your ideas. Let’s get moving on this!
For example, look at the code block to the right. This is an object that is called when the user clicks on the green flag button on the user interface. That green flag is how one starts a program in Scratch. This is hooked, literally, to a “forever” lop. Within the forever loop, execution (of that object) is delayed for a fifth of a second, then an “If” statement is executed. If the object linked to this object (such as a sprite that might be able to move around on the screen) has come into contact with something green, a chomp sound is made.
You will see scratch like coding in Lego projects, in association with various robot kits, and I suspect over time, with Internet of Things objects. The coding is so straight forward that even Mikey can do it.
Most of the LEGO books I’ve seen are pure idea books. If you wanted to build a project based on what you see in the books, you have to either have a huge collection of LEGO parts very well organized, or you have to be prepared to order several specific bricks that are called for in the books.




Its mascot is a cat, of course, but the name “scratch” supposedly comes from the use of scratching by disk jockeys. Scratch was first developed at MIT back in the early 2000s, and has advanced considerably since then. You now see the basic format of this language either duplicated or mimicked in many different environments.
