Google education updates
Interesting update from Google about what is coming to Meet and Classroom
September: 7x7 Grid view and digital whiteboard
October: blur or replace background, attendance tracking, breakout rooms(!)
Later: Hand raising, polling.
Nice to see them coming. i think there are extensions that do the same stuff too
More details on what's coming to Meet and Classroom
Education Group Product Manager, Google for Education Published Aug 11, 2020 50 new features in Meet, Classroom, G Suite and other products for students, parents and teachers. Read more Editor's note: On August 11, 2020 Google for Education kicked off a global back-to-school event, The Anywhere School.

MoviePass Obituary
-->
-->
So I spent $253.13 of MoviePasses money. In 10 months I paid them $99.50. So a net gain of $153.63 for me. MoviePass lost $153.63 having me as a subscriber! On the list there are only 5 movies I would have absolutely gone to see in the theater. Of the remaining ones, about half I would have gone to if one of my friends wanted to go. The others I probably wouldn't have seen.
I also literally bought into the hype and owned HMNY shares. I spent $94.29. During the reverse split I was cashed out because it wasn't a whole shares worth for $18.70. Yeah, they got me on that one for $75.59.
So putting to rest the MoviePass saga for me, I still came out ahead to the tune of $78.07 and got to watch a bunch of movies. It's no wonder they are going out of business.

MTE-514
These are the "blog" posts for the the discussion thread for my MTE-514 class from teacherstep.com.
Blog #1
Discuss sampling methods that could easily be conducted in a school setting to assist students in further understanding of the pitfalls of sampling.
There are 5 types of sampling techniques that can be used by researchers. . Each one has its advantages and its pitfalls. The five type are random, systematic, stratified, cluster, and convenience sampling.
Random samples are samples that are selected by using chance methods. As long as each member of the population has an equal chance of being selected, this method is the best for obtaining a non-biased sample.
In a systematic sample, researchers pick a certain number of subject to skip to obtain a sample. For example, every 10th production in an assembly line could be tested for defects. When using this technique, it is important to understand how subjects are arranged in order to avoid bias. For example, if subjects are order "husband, wife, husband, wife..." picking every 10th subject would give a sample that is all wives.
Stratified sampling divides the population into groups based on a characteristic that is important to the study, and then obtain data from each group. For example, high school students could be stratified by their grade level and then asked about their grade in their English class. Samples within the strata should be randomly selected.
Cluster sampling is useful when dealing with large populations. If there already grouping that occur, a few of these clusters can be study at random. Data from every subject in the cluster should be obtained. It is important determine if these clusters represent the population to avoid bias. For example, each classroom in a school can used as a cluster. Then a few classroom can be randomly selected as a cluster to obtain data from. If a 12th grade AP English class and a 10th grade Honors History class were picked, there may be a bias in the data, because these class may not be representative of the population of the school.
Convenience sampling is the techniques most used by students. It is the "man on the street" technique. This type of sampling can be very biased becauses students only tend to obtain data from people physically close to them, which tends to be their friends and family. If it can be determined that the convenience sample is representative of the population, it can be used. Otherwise, it should not.

Module 2 focuses on the use of different types of regression. Discuss how students interpret regression in daily use.
Regression for students is all about finding connections, hopefully predictable, between two things. For example, they might find that when their "low fuel" light comes on in their car, they still have 50 miles until they run out of gas, even if they gauge is past they empty. I might conclude that if they do their homework, their grades will go up. Or they might find that when they get a good night's sleep, they feel better they next day. If they go to a casino, they might notice that the odds are always against them and the house always wins, but people can still win money, and that's what makes it exciting.

Simulations are a great way to for students to see how probability distributions are found in actual data. Discuss how you would use simulations within experiments.
I use simulations to show how the central limit theorem is built. I simulate coin flips using a python program, which will then give a graph of the results. The program can simulate a few coin flips to see how the graph lines up with the binomial distribution. As I increase the number of flips it simulates, the graph keeps getting closer and closer to the normal distribution. This helps students connect the blocky histogram of the binomial distribution to the smooth curve of the normal distribution.
The other simulation I run for them is of the Monty Hall Problem. It is a very tough problem to think through logically, and even when we talk about it, the logical never seems to make sense. The program I write simulates the problems many times and give the chance of winning the car. Sometimes they still believe the logic behind it, but they trust the computer because they can see each result happening.

Discuss how sampling can be used to make inferences about a population.
One way sampling is used to make inferences about a population is a process called hypothesis testing. It is a decision-making process that evaluates certain claims about a population. For example, a drug company may wish to know if a certain drug can reduce the infection rate of HIV in MSM over another drug. Two groups of men will be selected and each group will get a different drug. At the end of the trail, the number of new HIV-infection for each group will be counted, and the hypothesis test would be run, and the data would be used to determine if the new drug was better at preventing HIV infections.

MTE-514 Intro
I need 3 more credits to move over a column in the teacher salary schedule. I decided to take an online course with another teacher from TeacherStep.com. I thought I didn't my due diligence before I signed up: Nope! I got the syllabus from them, and it looked like it was some readings and a few problems from the book as the assignments. Not even close. The only thing that is graded is 3 essays and what looks like a 2-hour final exam essay. You don't even have to go any of the math to get the grade. Really not was I was looking for. But I can finish it up pretty quick, so there is that.

Making Music with Linkbots part 2
It wanted to try doing some harmony with the Linkbots. So I ended up connecting 3 bots at the same time.
So here is the first movement of Moonlight Sonata.

Making music with linkbots
I'm going to start doing some music with my Robots Lab kids next week. I figured it would be good to get a demonstration going so I programmed the Linkbot to play Flight of the Bumblebee.
