I ended up with a class that saw confidence intervals as 4 separate things, and never once (except for those few exceptional learners) connected the dots to see that all 4 intervals, 5 actually, because you can have 1 prop z and 1 sample z, were all the same, exact idea separated only by what kind of data you have.

This year, while working with a colleague in another state (thank you @druinok and your blog) I learned that while the curriculum to AP Stats is pretty set, the creativity to teach it better comes from me. So, I changed it up. Last year, my problem was that the learners did not see the intervals as the same thing.

This year, I decided to teach all 4 intervals at the same time. Slight exaggeration. I taught the 1 prop z interval, and the conditions for it, and how to interpret, and how to do them. Then, I offhandedly mentioned, “and you know, there are other types of intervals we will get to as well.” In the restaurant business, that is called planting the seed. English teachers call it foreshadowing. I call it darn good stuff.

The reaction from the learners was immediate. “What are they?” “Are they different?” “How are they different?” were some of the immediate questions. So I went into them. Next I covered the 1 sample t interval. Here are the conditions, here is where you use them, etc.

They were hooked. The class, as a whole immediately saw that the intervals really weren’t all that different. Next, I made a worksheet with 12 problems. Several from each type, but purposefully NOT 3 of each type. Actually, 3 of the 1 prop/sample z, 2 of the 2 prop z, 5 of the 1 sample t, and 2 of the 2 sample t. The learners cut out the 12 problems, and had to sort them. There were a couple of purposefully tricky examples, like:

Suppose the average height of randomly sampled 100 male students at University of Reno is 67.45 inches with a standard deviation of 2.93 inches. Find a 95% confidence interval estimating the height.

The class put this in the “t interval” category at first, and that categorization would probably not be wrong on an AP test. It fits better in the “z” category though. Why? This was tricky because it doesn’t say we actually DID take a sample of 100. It says “Suppose ….” Yup, this is Mr. Waddell being a jerk and trying to trick the learners. But they got that. It was the only question worded that way on purpose.

At the end of class, the learners had 4 stacks of problems. I worked 1 problem all the way out using PANIC (Parameter of interest, Assumptions check, Name the interval do the math, Interval in correct notation, Conclusion in context). They had to pick 1 from each stack and do the problem.

They left class in good spirits with some very complex problems. They left feeling like they understood something important. I walked away chalking the last 3 days up as a success. Now it is just up to them to recall it.

Why? Because if we can get started on implementing some basic ideas of the CCSS now, then there will be less work to do later. It makes sense, and we jumped in with gusto.

…  crickets chirping …

Okay, perhaps we got off to a rocky start at first. But the entire department started coming together and thinking about what the Standards for Mathematical Practices really mean, and we all agreed pretty quickly that #3, Construct viable arguments, is going to be the easiest to implement right away, as well as provide some very useful impact in our classrooms. The same thing goes for 5 and 7, use appropriate tools and look for and make use of structure.

All of the 3 PLCs in my department started on a plan in their content areas (Alg 1, Geometry, and Alg 2) to begin to make plans and more importantly, IMPLEMENT the plan in their everyday teaching. I know I have seen a positive impact already.

Here is what I have implemented.

First, I model every problem I do with words. Here is what I mean by this statement on a very easy example, with some steps from the left side left out, nothing from the right.

2x + 5 = 5x – 4     [the problem]

+5 = 3x – 4     I subtracted 2x from both sides of the equation because 2x –                              2x= 0, and I only subtract from the 5x bcs they are like terms.

9 = 3x               I added 4 to both sides because –4 + 5 = 0, and like terms.

3 = x                 I divided 3 to both sides because 3 / 3 = 1, which gives me x all alone and the answer.

I noticed an immediate change in the lower level learners. They immediately started nodding their heads and following along. Of course, this was Alg 2, so the example we were doing was a rational radical problem, and the words were the only way they could understand what x^(4/5) means.

I asked them to do one problem exactly as above in class in the last 5 minutes, and I had over 3/4 of the class finish the problem in the time allowed. They did the work! More importantly, they were understanding the process. Writing out the because to every step gave them the structure to understand not just WHAT they were doing but WHY. They could explain.

Then we came to homework. I gave them the following assignment. 78-80, 83-85, 88-90, Pick ONE problem from each section, and explain every step as above.

I expected tons of complaining and whining. I did not get it. The assignments turned in were very good, with mostly decent explanations of why. There were some higher level learners who thought that the WHAT was enough. Next week I will hand them back and disabuse them of the notion.

The surprising thing to me was the number of ELL and SPED learners who turned in homework for the first time all year. Maybe because it was at the beginning of the semester and they turned over a new leaf.

But I am thinking that partially it is because they got to choose which problem they did, and they were explaining WHY they were doing what they were doing. It is still early in the semester, and I am not sure if it will continue. I will update more on this issue though.

As a first step to CCSS, I think it is a good one, albeit small. I will also report on some things other teacher in my department are trying. CCSS is slamming down on us hard, and we have to get ready now, not wait for our district to tell us what to do.

Short post: it worked, I think.

Long post: I passed out the scantrons, which immediately brought forth a groan. We just had the final exam last week, and I was already giving them a quiz! Once we got over that part of it, I asked a question.

I was giving them a 1 question quiz. What is the probability they would get it right? All they had is a scantron, no other papers or anything else, so they asked if they were just supposed to guess at the answer. My response was “yes” and quickly they had in hand that the probability was 1/4. It always surprises me how long it takes to get to that point with some learners though.  It is not as quick as I would think. But we all got there within a minute or two, which is faster than normal.

Next, I told them they were taking a 5 question quiz. And I asked the question, “what is the probability you will get a passing grade on the quiz?”

Now the frustration started. They wanted initially to just say (1/4)(1/4)(1/4) = 1/64.  Not so. I killed that pretty quick. But before I did, I wrote it in exponent notation, so they would be comfortable with the idea of exponents having a meaning in the problem. It worked.

The class started guessing lots of things then. (1/4)^3(3/5). That one was creative, accounting for the 3 out of 5 questions. I did not tell them what was right, but we had in the end 5 options the class thought were possible. One of the options was (1/4)^3(3/4). Pretty close to the basic part of the formula, just missing the fact they missed 2 questions, not 1.

So I asked them which of the options written down actually referred to something bubbled on their scantron. After all, 1/4 means something physical related to their scantron. They quickly ID’d the right equation as meaning something consistent,  and very quickly said they needed an exponent on the 3/4.

The last step was asking them how many different ways to get 3 right out of 5. I did the standard counting and after drawing 3 different options someone said, “there must be an easier way.” The class suggested permutations and combinations, and we quickly settled on the combination of 5 C3.

Done. In 15 minutes, we constructed the Binomial Probability formula using nothing but a stack of old scantrons. I then wrote the formula down for them, and they explained what the pieces were for. They made the connection much quicker than before, and I was really pleased with how fast they could plug numbers into the formula.

I remember last year just screaming inside because they could not get the difference between the probability of the problem as a whole, and the p and q values in the formula. They understand that now.

Success, probably. I like it.  Below is a jpg of the notes I made while doing the exercise.

 click to enlarge.

Provide each student with a scantron sheet and ask them to guess which would be the correct answer to the first question, if you were unable to see the question.. Talk about the percentage of the students in the class which would have guessed correctly. Extend this to two questions and so on. You can then talk about the math behind probability.

In AP Statistics, as well as the Algebra 3 class I teach, we do binomial probability. It is very abstract, and difficult material. For the Alg 3 course, we incorporate Pascal’s Triangle, as well as the combinatorials, and it becomes a very interesting lesson. But there are still always learners who can never figure out what I mean when I ask:

Now suppose you are taking a 12-question multiple choice test with four possible answers to each question. You need to pass the test in order to get ‘un-grounded’ for that crap you pulled last weekend.

1. If you are totally guessing on every question, what is the probability that you will get a passing grade of at least 60% on the test?
2. Suppose all those minutes of studying pay off and you are able to eliminate one answer for each question. Now what is the probability that you will pass the test and get to go out on Friday?

Yes, this is a real question I ask in Alg 3. The fact that you need 8 out of 12 questions right really stumps the learner, because they try to use that instead of the (.25)(.75) probability required.

But if they actually had a scantron in front of them, would they do better? I don’t know, having taught the material in Alg3 several weeks ago (before Christmas break). But my AP Stats class will be doing the binomial distribution this week. I am going to try it as an introduction. We can then extend the formula to the normal model afterwards.

I will report back what I find out. [which means that one of my goals this year is more active blogging and sharing. I have said that before, but never give up!]

What brings me to write about this chapter specifically is I have an interview next week for department leader, which is the de facto leader of our PLC. I am going to be (because success is the only option) our department leader, and if that is the case, I better be prepared for the interview and the challenges that come later.

First thing, what is my vision for our math department? What are the values that support that vision? What is my TPOV?

First, let me start with the values of my school. We have 6. Responsibility, Respect, Honesty, Courage, Loyalty and Success. These are the 6 values of the school as a whole. Anything I do as department leader must fit into these values somewhere.

My Vision for the North Valleys High School Math Department

By 2014, the NVHS Math Department will have the highest scores on the District end of course exams, and we will continue to meet or exceed all district mandated requirements for the NV Proficiency exams.

How we will do it:

1. We will implement Reasoning and Sense Making type problems at all levels beginning 2011-12.
2. We will increase the number of RSM type problems over the next 3 years.
3. We will implement the CCSS with fidelity across all levels, starting in 2011-12 (ahead of the district implementation).

There you have it. That is my vision for my math department. We are currently in the middle of the pack on the end of course exams, and we are meeting AYP proficiency goals. We were on a year 4 needs of improvement classification, but through a lot of hard effort, we pulled ourselves out (our consistent red cell was mathematics ELL and Special Ed.)

It will definitely take some Courage and Respect to implement this vision, but implementing will lead us to Success.

One reason I think this is achievable, is that out of the 700 teachers at the RSM Institute this summer, only 5 people from my district attended, and only 2 of them are high school teachers. Both are from my school. We have an advantage in learning, and we can leverage that advantage to overcome the obstacles that stand in our way.

Any comments or feedback on this vision statement? My interview is on Tuesday morning next week, so I need to refine this and sharpen it quickly!

Thank you!

The course is more project based, and it has four distinct, but overlapping sections. Quarter 1 is financial math, quarter 2 is math in art, quarter 3 is math in technology and quarter 4 is math in health / human body. If you go to the site http://mrwaddell.net/AAA you will see the basic structure and some of the lessons / sites I use to teach the course.

Starting off this year, I am going to do something different with the quarter 1. It always felt a little disjointed to me. We use the materials from NEFE to get us started, and then we jump in much much deeper than NEFE goes. We spend a lot of time on spreadsheets (which are nothing more than giant algebra problems using variables) polynomial equations and rational equations (another way to think of Pert and other compounding equations, ie. purchasing a car and annuities) as well as some basic ideas of personal finance.

This year, instead of just teaching each module as a standalone, I am going to tie all of the quarter 1 together with this outline.

At the end of this project, you will need to show the Banker your portfolio that demonstrates you have the financial knowledge and ability to purchase a house in the North Valleys.

Part 1: Setting S.M.A.R.T. Goals

1. Short term, medium term, & long term goals

2. Tracking your goals

3. Adjusting and rewriting your goals

Part 2: Savings & Compound Interest

1. Calculating compounding interest for n

2. Calculating compounding interest for continuously

3. Finding rate or time in both kinds of compounding (working backwards)

4. Knowing and demonstrating differences between APR and interest rate

Part 3: Career & Income

1. Identify 3 careers for yourself

2. Calculate lifetime earnings

3. Calculate $1,000,000 earnings timeline

4. Comparing 2 and 3 for your careers

Part 4: Purchasing a Car

1. Calculating your payment

2. Deciding on years of repayment

3. Comparing years to payment and making a good choice

Part 5: Investing & Credit

1. Risk vs. Reward

2. “Safe” vs. “Intermediate” vs. “Risky” investments

3. Annuities

4. Credit Cards

5. Credit Scores

Part 6: Budgeting your spending and savings

1. Creating a budget (will be working on all quarter)

2. Projecting income

3. Projecting expenses

Part 7: Buying your home

1. Put it all together for the Banker, and using the financial information gathered to justify to the banker that you are a good loan candidate

That’s right. The end goal and purpose of the portfolio will be to purchase a house. It is the biggest investment a person generally makes, but I also know of 4 learners who graduated within the last 3 years who are now homeowners. It is a reality they can achieve now, whereas 3 years ago it was out of reach.

The purpose of this structure is to create a buy-in. Now they see the end goal. This goes hand in hand with backwards design and Understanding by Design principles. I have emailed out a draft to the other Advanced Algebra teachers, and once I have it more fleshed out I will email out another copy. I also hope to get some feedback from them to see what they would add as well.

So, what do you think? Is this a viable way to put together a quarter on personal finance? Let me know in the comments.

Outside, the place looks like any tourist trap.

Do they really have 50,000 silver dollars inside?

And at the back of the bar they have a sign saying what the current count is. I visited twice, 1 year apart.

In July 2010, it looked like this:                    In July 2011, it looked like this:

Any Questions?

[Please leave me some challenging questions in the comments. I am looking to develop this into a classroom material lesson. I also have more pictures of the inside, I just posted a few of them here.]

A collection of all the posts, organized by days.

Day 1:

Am I creating more “Clever Hans’” – Notice the plural on the Hans. My answer in general is no, but that may be overly simplistic. It is something that must be fought every day. The rest of the post is about Dan Meyer’s challenge to reform math education is even more important!

Day 2:

Reasoning and Sense Making day 2 – Most of the great resources I found are in this posting, along with some fabulous ideas for Algebra and factoring.

Beth Chance, Henry Kranendonk, and an overwhelming task in stats – Beth Chance and Henry Kranendonk went through how to teach a lesson using Reasoning and Sense Making. Very powerful to actually have someone demonstrate it.

Day 3:

PLC’s at work with Timothy Kanold – A very powerful look at what the impact of PLC’s can be, and how to evaluate your own PLC. The best quote I wrote down that I must bring back to my department and ask ourselves daily is:

Do we want to be known as a school where the math department’s decisions are based on best practices and evidence or as a school where the decisions are based on opinion?

Landy Godbold & “Given That” shown visually – This session started off slow, but ended with a bang! Great ideas were taken away from this session and will be used in class.

Viva Hathaway & stats with food! – Viva is an epic teacher. We didn’t spend enough time doing what I would have liked, but her personality and energy is really the motivating factor in the room. I will attend more of her sessions if given the chance.

Random thoughts and musings that don’t fit above.

Tweet Archive of #nctmrsm11 – There were very few teacher tweeting at the event. Internet was an issue, power was an issue, and it made things difficult to do create electronic versions of the talks. But, some powered through! I won’t make any claims to the accuracy of the archive, but there it is.

1. One of the goals of the Institute was for the participants to walk away with an action plan to implement RSM in our classrooms. Notice that nowhere did I speak to my plans! I have one. I wrote down two pages of things I will do, but I didn’t want to spell that out yet. Part of the issue is I was blindsided by some news at the institute about another teacher. I can’t go into details, it isn’t public yet. But it radically altered my plans and what I need to do.

2. I noticed that as the institute went on, I became a better participant. My notes became better and my thinking sharpened. Just look at the postings above. Day one to day 3 shows a marked distinction in the quality of postings, and what I took away changed as well. This is only the second conference / institute I have attended, and I need to attend more. Before I do, though, I need to go back and read these postings to develop that sense earlier rather then later.

3. Finally, all this was money and time wasted if I do not actually put forth the time and energy throughout the school year to actually DO reasoning and sense making in my classroom. It must become a habit for it to be successful (Beth Chance), it must be implemented with fidelity throughout the department (Tim Kanold), it must be done with energy and enthusiasm (Viva Hathaway), and it must be done with tools that the learners will relate to and engage with (Dan Meyer). That is the real takeaway I have from the 3 days I spent in Orlando.

I have that book on my bookshelf at school, and I have looked at it, but have not tried any of the lessons in it. I read the lessons at the end of last year, and said to myself, “Are they crazy!” “I don’t understand what they are getting at!” and “Maybe next year.”

After their session, where they essentially went through several of the lessons in fairly good detail (the Old Faithful Data and the Will Women Run Faster than Men in the Olympics as well as others) I am much more confident of doing the lessons successfully.

They had a handout of the material, which I scanned and you can download here.

I apologize for the missing data on the women column, but my copy was very faint also. However, if you go to the book link above, the “Read an Excerpt” is the full chapter from the book in PDF form! Yay!

I am not here to sell their book though. I feel the book is worth buying, now that I have spent better time with it, but the front side of their handout scared me silly.

Go ahead, download it now. I will wait and get some coffee while you do.

….

See what I mean? Under “Habits of Mind in Statistical Thinking” they have 24! bullets under 5 sections. Here is my problem with that list. A habit is something you do unconsciously, because you have done it so often and so repeatedly that it becomes second nature; like breathing.

How can a list of 24 bullets become second nature? The first and second time I read this list I just got a sinking feeling in the pit of my stomach. If this was successful Stats teaching, then I have been failing. Clearly something has to change in the way I teach Stats and what I teach in Stats.

And then it dawned on me. What must change is the quantity of Reasoning and Sense Making I do in the course. After all, let’s examine the list, not for the whole statements but just the root verb stems.

describe, analyze / analyzing (2x), looking for, making deductions, choosing, creating, considering, drawing conclusions, comparing (2x), evaluating (2x) questioning, applying, noticing, identifying, understanding (2x), connection, considering, determining, justifying, and looking for

When you get rid of the other language, the details of what the statements are, and focus on those verbs right there, it is easy to see how a habit can be formed. It is not hard through repeated effort to construct those habits in learners.

See, all those verbs have something in common. They all have Reasoning and Sense Making (RSM) as their goal. Anything I do in class that does not have the goal of RSM is officially a waste of time. There it is. There is the big takeaway from the session.

I just figured out what every lesson I teach in AP Stats needs to revolve around. Now I just have to rewrite all of my lessons to focus on that. That will be the subject of many more posts.

——

As an aside, Beth used some dice and applets in the session that were very cool and useful. The Dice showed an 11 in 6 out of 9 throws. I searched for something that would do that, and found them here and here and here again. These are very useful to generate some statistical thinking skills in the learners.

The applets she used can all be found on the RossmanChance.com website. There are additional materials on this site from other presentations they have given. I may end up using her applets almost exclusively, just because they are all on one site. It makes life easy.

Then, when I got home, I searched for the hashtag on twitter, and scanned the two lists to see if there were any differences, copied and pasted the missing ones into the list. Have I probably missed some? Yes. It is hard to get an archive out of twitter. They don’t make it easy, by any means.

Anyway, this is probably the best I can do at the moment. I still have at least 2 articles to write from the time in Orlando.

Earliest to latest order: Monday, 1 Aug on top, 28 July at bottom, after the break.

@NCTM #nctmrsm11 The lack of wifi and therefor a good twitter stream and makes it impossible to follow You’re losing so much.

#nctmrsm11 @ddmeyer 1st presenter that follows good presentation technique & doesn’t stand next to the screen when using remote. Thank you.

My point exactly #nctmrsm11 RT @lmhenry9: I am trying to type up stuff and blog it later. No WiFi means I can’t type notes and tweet.

@ddmeyer eekk! I guess I keep thinking about all that reasoning & sense making going on & want to put it 1st. on the ball now #nctmrsm11

#nctmrsm11 instead of x2 -7x + 12, which has no reasoning, how about x2 -?x +12. What possible answers are their now? Integers? Fractions?

@NCTM #nctmrsm11 yes, Lisa’s post was great. Was working on my own but fell asleep! Too much to do, not enough time.

#nctmrsm11 (gary martin) we don’t always need contextual problems, but interesting problems. Think of soduku, many people do them.

@

@NCTM #nctmrsm11 the time allowed to actually work, not just listen. Much higher level of engagement by audience. Oh and of course @ddmeyer

#nctmrsm11 how’s the institute been so far? what’s been your favorite part?

29 Jul

gwaddellnvhs Glenn Waddell, Jr.

@

@jybuell I agree. Only place to get internet in hotel is in or in front of Starbucks. Sad that Starbucks is the default internet. #nctmrsm11

@

@gwaddellnvhs that’s stupid. It should be part of the conference. #nctmrsm11

gwaddellnvhs Glenn Waddell, Jr.

#nctmrsm11 what is it we would like to get from our learners (Gary Martin) recall, mimicry, or thinking, reasoning & sense making?

29 Jul

gwaddellnvhs Glenn Waddell, Jr.

@

@jybuell #nctmrsm11 internet is huge issue here. Hotel charges $15 per day for access. It’s a joke. Thank goodness I have unlimited on phone

@jybuell its because we are trying to listen and write as we are tweeting too! #nctmrsm11

RT @climeguy: @jybuell NCTM should have staff at #nctmrsm11that’s doing the tweeting. They should made aware of how you feel about it.

#nctm need to hire some professional tweeters for its conferences. They’ve got the worst twitter streams. #nctmrsm11

ddmeyer Dan Meyer

To all six of you following the #nctmrsm11 hashtag, they have me doing a second session if you couldn’t get into the first. Ocean #4 @ 2PM.

If you did not make @ddmeyer 9:45 session, he will do it again at 2p in Oceans 4 in place of a cancelled session. #nctmrsm11

Great 1st day at #nctmrsm11! Loved opening session w/ @ddmeyer – now the whole 3 act thing makes more sense to me. Will blog later.

Great 1st session! Thanks @ddmeyer! Like a new set of eyes to see the math and questions around us to reason and make sense of. #nctmrsm11

@ddmeyer thoroughly enjoyed your talk at #nctmrsm11 this afternoon. I’ve used that Little Big League clip in my classroom. Good stuff.

#nctmrsm11 Textbooks rob students of the ability for sensemaking. @ddmeyer & Clever Hans’ grow up to teach math to other Clever Hans’

#nctmrsm11 in the math classroom we are really good at creating Clever Hans’. @ddmeyer

@lmhenry9 seriously? #nctm is a constant fail when it comes to wifi access Didn’t you have that prob at the national conf too? #nctmrsm11

lmhenry9 Lisa Henry

No WiFi in here. Not sure how much tweeting I can do but I will blog about #nctmrsm11. You just may have to wait for it.

There is WiFi but you need a username and password for #nctmrsm11. Boo.
