Late Project Submissions

Do not hesitate to submit your projects even now! There will be a penalty (unless you are the student who brought me a note from your mom regarding a computer virus), but it will be insignificant. My email for submissions is amann@fz.k12.mo.us and the paper should be sent via rtf format...otherwise my old Word 2003 will interpret it as nonsensical characters which hopefully it is not.

Happy Holidays and/or Merry Christmas!

Stat Tests

Well...........

Bad teaching?

Bad learning?

Some combination of the two?

Solution:

Decide upon receipts of your "test" if you will keep that grade or try again. We will go over them and those who wish to try again can. Then this will be a practice test. If you try again, you keep your second grade. You can decide after we go over them what you want to do.

Are you frustrated? So am I!!!

There were good grades...80's, 90's, and 100's. Good job to those folks!!!

Irrational Taxation?

Nope...not going where you think! I have a passing interest in politics, but this is more about psychology and knowledge of mathematics. I enjoy the looks at life from Freakonmics, named after a book by the same name. They look through the lense of economics at various aspects of life. There is much in the way of math in these observations, perhaps none more so than this idea on taxation.

A quick 2 or 3 sentence synopsis of this article will earn you 5 bonus points. The article can be found here. I will not mention this in class and you have until Monday of next week (11/2) to turn it in.

Project Ideas

Follow the link below to see all (and more) of the project ideas we discussed in class. These might be ones you can actually do...or perhaps spark an idea. You have some basis for analyzing the data, but as I mentioned in class, we will continue to add to the repertoire of tools you have at your disposal.

Project Ideas

Today's Wrap-Up 10/20/09

• Algebra II...Test tomorrow. Nothing tricky. You have had ample time to prepare. Go in and do your best and don't let nerves get the best of you. Really no memorization necessary for this one. Make sure you check answers on systems of equations. You should know on each of these if you got them right or not because you can check your work by substituting back in. On linear programming questions, make sure you show work. There will be partial credit awarded. Don't leave anything blank.
• Pre-Calculus...Test Tomorrow...Focus on manipulation of complex numbers, graphing quadratics, and graphing other polynomials using the leading term tests, finding x and y intercepts, using symmetry, etc. Obviously know the basic formulas and equations like the quadratic formula and the equation for finding the axis of symmetry for a parabola in standard form (x = -b/2a). Show all your work and check work if you have time.
• Statistics...Took Ch 4 Test...Of tests completed, grades look great! Some silly mistakes...will go over tomorrow. Next on the agenda is some discussion tomorrow of projects. Be thinking of areas you would have some interest in doing statistical analysis...Ideas might include sports, occupations, etc. Will get into specifics tomorrow.

Statistics Article

Here is a link to the article we discussed in statistics class today. Let me reiterate that I DO NOT assert that smart people in general make less money. However, I am asking you, in one paragraph, to provide a logical and plausible explanation for why there could be a negative correlation between intelligence and income for individuals with Bachelor Degrees and a positive correlation for those with other degrees (HS diplomas and advanced degrees like Masters or Doctoral degrees).

Where is Your Focus?

The scene: Washington D.C. Metro Station on a cold January morning. He played six Bach pieces for about an hour. During that time, approximately two thousand (2,000) people went through the station, most of them on their way to work.

After 3 minutes, a middle-aged man noticed there was a musician playing. He slowed his pace and stopped for a few seconds and then hurried to meet his schedule.

4 minutes: the violinist received his first dollar. A woman threw the money in the till and, without stopping, continued to walk.

6 minutes: a young man leaned against the wall to listen to him, then looked at his watch and started to walk again.

10 minutes: a 3-year-old boy stopped but his mother tugged him along hurriedly, as the kid looked at the violinist. Finally the mother pushed hard and the child continued to walk, turning his head all the time.

Several other children repeated this action.

Every parent, without exception, forced them to move on.

45 minutes: the musician continues to play. Only 6 people stopped and stayed for a while.

About 20 gave him money but continued to walk their normal pace.

He collected $32.

After 1 hour, the musician finished playing and silence took over. No one noticed, no one applauded, nor was there any recognition.

No one knew this but the violinist was Joshua Bell, one of the best musicians in the world. He played one of the most intricate pieces ever written, with a violin worth $3.5 million dollars.

Two days before Joshua Bell sold out a theater in Boston where the seats averaged $100.

This is a real story. Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of a social experiment about perception, taste and people's priorities.

The questions rose:

In a commonplace environment, at an inappropriate hour, do we perceive beauty? Do we stop to appreciate it? Do we recognize talent in an unexpected context?

One possible conclusion reached from this experiment could be:

If we do not have a moment to stop and listen to one of the best musicians in the world, playing some of the finest music ever written, with one of the most beautiful instruments… how many other things are we missing?

The Week Upcoming in Stats and Pre-Calculus

First, good luck to all the sports teams competing this weekend. My son will be at McNair Park running for Washington HS CC Team so I will be there for that.

The turnout was great for Thursday's review session and obviously it is my hope it will be of help to those who attended!

• In Pre-Calculus, as I am certain you are well aware, we will have a test on Monday. We have prepared well, in my opinion, and if you study some over the weekend, I believe you will do fine. Focus on the items emphasized in class during the review on Friday. The only items that come to mind for memorization, are the rate of change formula (really just like the slope formula), and the transformation rules and the order in which they must be performed. As always, you will have access to notes the final few minutes of the test, but you will not have enough time to do a lot in this time. While this will be the last first quarter test, I will get one quiz on the agenda prior to quarter's end. Remember there is a review session on Monday morning in Room 111 with Ms. L. Also, the answers to all the Chapter Review problems are in the back of the book.

• In statistics class, we will be testing sometime next week, tentatively on Thursday. This chapter has only three sections, the first we covered today. We will likely do a Case Study from Chapter 4, but we may do so after the test. After the Chapter 4 Test, we will begin to focus on getting our first project rolling.
  

• As we have a total of 11 chapters to cover, and we will have covered four of them a week prior to the end of first quarter, we will have some time to start applying what we have learned through projects. It is my feeling that this is where the material starts to become meaningful as it is applied in the projects.

Test Anxiety

I am skeptical sometimes when students tell me they get "test anxiety." I know it is a real phenomenon for some, but like many other ailments, it can be over-diagnosed. Even if you are pretty sure you really have it, there are things you can do to help yourself. Try reading this page on overcoming test anxiety and how to study for tests. It really might help.

One positive way to look at the situation, is that if you really do have this "problem," for one thing it means you care enough to get nervous. In the long run, this fact will likely serve you well if you are willing to work hard to overcome it. Taking advantage of test study sessions offered is one way to help some as well. Finally, do not be afraid to talk to me about it.

9/28/09 End of Day Update

• Algebra II tests are graded but not entered in SIS as system was down for a significant portion of the day. You will receive them back to see tomorrow.

• In Pre-Calculus, we did not quite finish notes over section 7 and thus I did not hand out worksheets. You will get them tomorrow. The test is delayed until Monday. Remember when graphing the functions in section 6 to follow the order we discussed. Also, a function of the form. f(x) = (-x+2)^2 + 3 can be alternatively written as f(x) = [-(x-2)]^2 + 3 and thus involves a reflection across the y-axis.

• In statistics, we discussed Counting Principles including the FCT, permutations, and combinations. Homework will be done over this section tomorrow and I will also assign the Ch 3 Review. We will push this test back until Thursday. This will give us time to rvw on Wednesday after you have looked at review assignment.

Pre-Calc...The Week Ahead... (week of 9/28/09)

This week will be hectic. On Monday, we will finish the notes from Friday. Additionally, we will go over notes for the next section. This week we will be covering sections 7 through 9 from Chapter 1 and taking a test on Friday. This means tentatively, we will go as follows:

• Finish section 6 notes (5 minutes worth) and cover section 7 (10-15 minutes) with a worksheet handed out for section 7 on Monday. Remember we still need to grade section 5 homework b/c I extended due date for those who had trouble.
• On Tuesday we will grade section 6 homework and answer ?'s on worksheet from section 7. I will then give notes on section 8 and announce hw from this section.
• Wednesday, we will grade worksheet and answer questions on section 7 followed by section 9 notes (very brief) and homework.
• Thursday we will grade section 8 and 9 homework and have time to review. There will be after school help on Thursday (with me) in prep for test as well as at 7 am the next morning in Rm 111 with Ms. L.
• Friday...Ch 1 Test

For those wanting heads up on HW...here it is...

• Monday...Section 6 HW previously given plus Worksheet.
