Shared Prosperity

I wonder if I know any of the "losers" in this change in the business tax.

http://www.michigan.gov/documents/gov/MBT_Overview_-_Final_179275_7.pdf

My students and I are the losers in the current legislation. I'm just saying. Share prosperity, you know...


And those seniors who don't pay any taxes, they've been dodging this burden too long!*

*holy sarcasm, Batman

Really? I'm over-payed?

Do you really believe that to fund the State of Michigan and at the same time make budgetary concessions to spur economic growth in our state we need to take it from the education system and public employees in general? And don't start believing statistics that say that as a public employees I'm over-payed. Those statistics try to contrast my wages/earnings (and my 7+ years of schooling, and endless years of retraining) with those of the uncertified/HS Diploma job holders. Compare my job to jobs that require similar levels of ed/training and you will see that the public sector lags behind in wages (-3.3%), and keeps up only because the benefits are better on average (+5.3%). However, public sector professionals are beaten out in total compensation by private sector professionals overall (-0.7%). (Data for calculations source: U.S. Bureau of Labor Statistics, March 9, 2011).

So when you say I'm over-payed, check your sources.

All that not withstanding, it's not what any teacher would tell you is the main point. The real problem (in Michigan, at least) is that they are taking money from the children (no joke!) because MI schools are financed based upon the students served and in my area the students go where they want to for school. The parents can "vote with their dollar" because their student, again in my region, is worth approximately $7,000 to a school district's funds. The current MI budget proposal will decrease this by over $700, over 10% of the "student" money is taken away. I don't have to tell you what this implies, but I will tell you that the old adage 'you get what you pay for' comes to my mind.

Don't mind me, though. I'm not really a professional. I'm just a middle school math teacher with a B.S. in general mathematics, provisional teacher certification, a Master's in education, and a bill for $1,400 for a pointless class the State made me take to get my professional certification.

Nice graph, Rep. Paul Ryan

Found on Rep. Paul Ryan's facebook page, a presumed accurate "fiscal prediction" made by the Heritage Foundation:
This is hilarious! So based on the most recent "War on Terrorism" you (the Heritage Foundation) and your mish-mash of "compilations of data" somehow predict that in the next 20 years nothing will change and we won't have learned anything from our history???

Trig/Pre-Calc on Moodle



Here is a link to our course page on Moodle. This page contains a weekly schedule, with homework assignments, useful links, notes, handouts, etc. You should get a free Moodle account as most teachers in the school only allow access from registered users to their courses. If you just wanna browse the page then you can log in as a guest. No matter what, you need to know the enrollment key. If you don't know the enrollment key, then pay attention next time in class.

TI Emulator

I found a TI emulator so you may use a TI-83 or 84 calculator on your home computer. There is one minor problem, which is that if you do not own a TI graphing calculator you cannot use the emulator since it requires a ROM image from your calculator which requires you to hook your own TI to your computer (see, getting a ROM image for help). However, if you would like to use your calculator on your home computer at anytime you can download any of the free programs from ticalc.org, then get the ROM image from your calculator by following the instructions on this site. Good luck!

Attention to those students who have Einstein’s Theories Topic #1 (General Relativity). I have changed the wording for the first three statements. The ideas are still the same so you do not need to research again, this is just to help clarify what is meant by the first three main ideas for your topic.

1. Describe the how gravity changes the space around a large mass.
2. Discuss the difficulty of visualizing curved space-time and the fourth dimension.
3. Discuss the similar effects for objects experiencing gravity and objects undergoing acceleration.

TEST ALERT - This Thursday 05/01/08

This Thursday an assessment (test) will be given on the topic of light waves. The topics to be included are:
  • Light emission by atoms ("How Light is Made in Atoms" answers)
  • Refraction of light (page 504)
  • Solving for frequency and wavelength using the wave equation (page 525)
  • Why certain objects reflect certain colors (page 535)
  • The different types of electromagnetic waves (page 526-527)
Notice the pages are given so you may study these topics tonight. We also had many discussions/notes about these topics that you should review to prepare for the test. A tutorial session will occur Wednesday after school to review and prepare for the test at 3:35.

TEST ALERT - This Thursday 04/17/08

This Thursday we will have a test about Mechanical Waves in Physics. To prepare for this test you have been given a study guide. Completing this study guide will help you review the ideas. To prepare for this test further I recommend that you read and reread the following pages in your blue physics textbook:

In Chapter 20, pages 434-447
In Chapter 20, pages 456, 457, 459-460, and 469

To be extra prepared, the chapter review on pages 450-452 will be helpful.

ALERT - Test Thursday

We will be having a re-assessment related to speed calculations and experimental design Thursday, April 3rd. We have recently reviewed speed calculations involving wave speed and have been discussing lab variables at different times throughout the year. Since every science class requires an understanding of experimental desig, students are being re-assessed to be assured that they have retained these understandings. Students received a review packet to prepare them for this assessment on Tuesday and should complete those questions to be ready for the re-assessment.
