(Revised) Evaluation of the Results format

Evaluation of the Results

“Old” Design of the Can	My “New” Design of the Can
Radius, r = _________ (don’t forget the units) Height, h = _________ Volume, V = _________  (don’t forget the justification for each step) Surface, SA = ____________	Radius, r = _________ (don’t forget the units) Height, h = _________ Volume, V = _________  (don’t forget the justification for each step) Surface, SA = ____________

 

Check to see if the surface area decreased

Remember that the whole PBAT was about minimizing the surface area while maintaining the volume.... check and double-check to see if your new surface area indeed is smaller than the old surface area

Extensions for the PBAT

1. Percentage of difference - Surface Area: Research what the percentage of difference is and find and explain the percentage of difference between the old and new surface area
2. Domain and range: Research what "the domain and range" of a function are, and find and explain the domain and range of your surface area function.
3. Significant digit: Research what the significant digit is and find and explain what significant digits we should keep for our project.
4. (Updated) Try an alternate approach to confirm your findings (hint: solve the volume formula for r, instead of h) and show that your results are still the same.  Make connections between the two approaches.

Don't forget to fill out the form to create your models!

A sample letter to a company for the PBAT - The Can Project

I just wrote a sample letter for you to read.  I actually had a lot of fun writing this letter.  I hope you have fun while you write yours.  I might have put too much silliness in the letter, so please refrain from using too much of that.  Otherwise, good luck!  Don't forget that the first draft is due next Tuesday, 5/18.

Link: http://docs.google.com/Doc?docid=0AUBUAGv_lfh1ZGR6N3Q4Nl8yNTlkZHFqa3Nncw&hl=en

Due Dates for the letter - PBAT: The Can Project

Next week (The 3rd week of May)

• Creating models of the old and the new cans - (M) 5/17/10
• First draft of the letter - (T) 5/18/10

The week after next week (The 4th week of May)

• Second draft of the letter - (T) 5/25/10
• Final draft of the letter - (F) 5/28/10

Then we will have two weeks in June to prepare for the presentation.  The first week of June would be used for preparing slides and speaker notes.  The second week of June would be used for mock presentations.

What we have done and what we still need to do

Here's a link to the document that lists what we have done and what we still need to do regarding the PBAT: The Can Project.
http://docs.google.com/document/pub?id=1XUlWuXyw4Hk3CFnf-81K5N1SKuz1urkMqftjMxaRrBM

The contents of the document are also pasted below.

PBAT: The Can Project

What we’ve done (not in order)

What we still need to do

Measured the can’s radius, height, volume, and surface area Combined the volume formula and the surface area formula by solving for height Graphed the generalized height by varying the radius without changing the volume Found missing radii (given the volume and the height) or find missing heights (given the volume and the radii) Described the tables and the graphs Found the new surface area function by solving the volume formula for the height and substituting the new height formula into the surface area function Found the minimum surface area

Create models of the old and the new can Write a letter to the company that explains the benefits of your new design compared to their old design. Revise the letter to complete the 1st, 2nd, and 3rd drafts Prepare for the presentation by creating the slides and writing the speaker notes

Exit Slip 9. Connecting the volume and the surface area functions for my can

1. Application: How is your new surface area function going to be used for this PBAT? What is the ultimate goal of finding this new function?
2. Multiple Representation: How would you use this function to visually represent the relationship between the height and the surface area of your can?

Exit Slip 8. Connecting the volume and the surface area formulas

Write your response as a new post on your blog.

1. Why is it necessary for us to combine these two formulas (the volume and the surface area formulas)?
2. Connection to your can: What would you need to do if you were to apply the same skill to your can?  Write the steps that you would take.

Importance of “comments” and “labels” of each post

As we get closer to the writing part of your PBAT, the comments and labels will increasingly play an important role for all of you.  First of all, the exchange of ideas will help you recognize different perspectives.  Secondly, you can search your own blog with key words if you need ideas or descriptions of a concept or an activity.

Therefore, please don’t forget to keep reading comments on your posts and writing comments on other students’ posts, as well as labeling each of your post.  We will have a day in May when I will be pulling up a random blog in class to see how many of you are commenting on others’ posts.  Hey, it’s May now!  It will happen soon.

Please remember that comments should be focused on helping others mathematically.

Exit Slip 7. Questions on overall PBAT

Review: What is the overall task of this PBAT? Mention all of the following terms when answering: radius, height, volume, surface area, cans, the company, consumers.

Exit Slip 6. Solving for different heights for my can

1. What was the important concept of today's lesson?
2. What mathematical tool did you use today? Why was it helpful? How did using the tool make your job easier?

Finally… the Community Box Maker project is graded based on the Consortium rubric.

Review the “Scores” and “Points” carefully in Edline.  I usually upload all of the details so that you can understand how you ended up with your grade.  Please do not just look at the overall grade and then ask me why “you got this grade.”  If you say that to me, I’ll know that 1) you’re not reading the class blog, and 2) you’re not reading the progress reports correctly, in which case, I will need to deduct points from your project.

Still, I anticipate that some of you may agree with the grading and some of you won’t.  Either way, please take a look at the Consortium rubric one more time, and then come and talk to me.  We have a lot of work to do with the current project, so if you’d still like to talk to me about the project grade after reviewing the Consortium rubric, let’s have a grade conference during the tutoring time.

Exit Slip 4. Measuring the volume and surface area of my can

How did you help each other today?  What were you able to accomplish?  What skills did you learn?  How would you use these skills outside of school?  If you were to pick one thing that you still have a question on, what would it be?

If you did finish the report, I will be putting on some final comments to help myself evaluate your report. You might as well read those comments, since they may help you with your PBAT.

Good job, everyone! This project has been a tough one, and many of you performed with gusto, most of you did well, and some of you learned what to do differently for PBAT.

Report Rubric

Here's the link to the rubric.

New York Consortium Math Performance Based Assessment Task (PBAT) Rubric

Your Scanned Graphs

If anyone does not see their submitted graphs as picture files in the Google Docs folder, please let me know. I scanned all of the graphs that have been submitted so far and put them in the folders.

If you submitted the graphs to be scanned, but don't see a Shared Folder in the Google Docs, that means I need your email address.

Writing Your Mathematics Report

Scholarly papers in mathematics use a variety of different formats and themes. For this practice PBAT project, here's my suggestion.

Title

• The title conveys the central point of your task. Be short and direct. “Celebrating with Fireworks: Applying Quadratic Functions.”

Focusing Question

• This is the question that you're ultimately answering with your conclusion.

Introduction

• Tell the readers what they need to know in order to understand your Body section.
• This should give the basic outline of what's going to be in your document.

Body

• Explain the process. Break down the major steps of your task into paragraphs.
• Explain what your tables show. (Also explain each design's function.)
  

Conclusion
This is your ... "So what?" Your body explains "what happened." So, what can you conclude from it?

• State what you can conclude from your work.
  

Discussion

• What can you infer from your conclusion?
• What is the best design according to your conclusion?
• Why do you think so?
  

Inquiry Process
D.O.L.-type reflection

• What did you learn?
• What would you do differently?
• Why was this project useful?
  

Work References

• Who did what?
  

Acknowledgments
Give thanks.

• Who helped you?
• How did they help you?
  

Figures and Tables
All of your tables and graphs should go here.

• Number each table as "Table 1, Table 2, Table 3, etc..."
• Number each graph as "Figure 1, Figure 2."
  

Appendix
Any extra information goes here. Did you do a table that you did not include above? Include it here. Any extra graphs? This is where you put it.

Homework for Today (T) 3/2/10

Create a new post that describes how much progress you have achieved as a team today. For example, how many tables did you complete? Did you find the maximum volume? What new designs did you try?

Naming Your Team

You will be naming your team after a famous activist. An activist is a person who brings about political or social change through the policy or action of using vigorous campaigning. For example, your team may be, "Team Jane Goodall."

Skim through the following websites and, as a team, pick someone you like and the quote. That should go on your title page later on, so write the person and the quote down as a new post on your blog.

I may talk to you further about naming your team if, for some reason, your team name needs to be changed.

Extra credit

I hope everyone's enjoying the break. Here's the extra credit task.

Look up the shipping supplies from USPS website, and see if there are any boxes that have the same dimensions. If so, what are the dimensions and its volume?  If not, what are some boxes that have similar dimensions and volumes?

How to post your response: post your answer NOT as comments here, but as a new post in your own blog.

Time for break... until the extra credit assignment

I'm glad that you've learned how to use blogger and Google Reader this past week. You deserve a break... but there will be an extra credit assignment posted on my blog. Don't forget to check your Google Reader for it.

Your comment on the project

One of your comments was asking when Community Box Maker project will actually start. This is a very good question!

We will start the project as soon as we're done with learning how to effectively and efficiently use blogging/commenting, and the last step is this: Google Reader. This Google Reader collects all the blog posts that you're following and put them all in one place so you don't have to type in twenty different URLs every time you want to read the posts published by your classmates.

11.1 is on their way!

Today, we set up 10 students' blogs in 11.1. Two down, two more classes to get started on blogging. Also, more comments have started streaming in. They were valuable comments about starting to use this new tool and how it might or might not be helpful. My general comment back to those were, "Once we start our Community Box Maker project and you read and comment on what others are thinking and wondering about the project, you will start seeing the value of using this great tool."

In 11.4, we started following at least 10 others and commenting.
