Google Classroom

All of Mr. McLain’s classes are currently using Google Classroom for communications and to manage assignments. That means this page is rarely used and seldom updated. Google Classroom does have a feature to allow you to get periodic emails regarding posts and assignments on the classroom.

If you are a parent or guardian interested in getting updates from the classroom, please contact Mr. McLain directly.

Tech Apps Lesson for 11/4/2016

Sorry I couldn’t be with you all today. Today’s lesson is focused on lying with charts.

Here’s an example from 2012. Take a look at it and see if you can figure out how this chart perhaps misrepresents the data as it is labeled: fbn-cavuto-20120731-bushexpire

Next, I want you to read through this:

And then, I want you to try it out with your political analysis. Can you misrepresent the numbers to show media bias that doesn’t match reality — without changing the actual numbers?

Sample Code for working with Sonar Sensor

Here is the sample code for working with the sonar sensor in RobotC


#pragma config(Sensor, dgtl2,  sonarSensor,    sensorSONAR_inch)
#pragma config(Motor,  port1,           leftMotor,     tmotorVex393_HBridge, openLoop)
#pragma config(Motor,  port6,           clawMotor,     tmotorVex269_MC29, openLoop, reversed)
#pragma config(Motor,  port7,           armMotor,      tmotorVex393_MC29, openLoop, reversed)
#pragma config(Motor,  port10,          rightMotor,    tmotorVex393_HBridge, openLoop)

|*  This program uses a single joystick, either right or left to drive the robot. Use notes below     *|

Introducing Google Classroom

For this trimester, I am working on using Google Classroom to manage posts and assignments for the classes. This provides a number of advantages of a standard web site (even one as robust as WordPress).

In particular, Google Classroom recognizes the difference between assignments and regular posts, and it offers the ability to submit assignments through the web site. It allows me to add comments and Continue reading Introducing Google Classroom
