Hi Kathy,
These are both nice demonstrations of ways to use the Sampler plugin! I couldn’t resist making a distribution of percentage of “Make” for each of the numbers of selection (see enclosed pic).
I found myself wondering what you think about whether HS students’ after a couple of sessions with the sampler would come to understand it well enough to make simulations from scratch?

Hi Heinrich,
Make sure the case table for the data you want to export is showing. Click on it to make it active so that the inspector menu shows. Click on the ruler to bring up the menu as shown in the screenshot and choose Export Case Data. Following through the dialogs will allow you to save the data as ‘csv’ either to Google Drive or to your local computer.
Hope that helps,
Bill

Hello Christián,
NetLogo Web now has the ability to add CODAP integration as an extension. To learn about this, take a look at the slide presentation that Kit Martin of the NetLogo group did last February. It’s in this folder.
I hope that has what you need. It’s pretty cool! You don’t have to mess with the html at all.

Hi Gabriella,
I’m deferring your question about log data to Jonathan Sandoe who has recently been working in that area.
Regarding embedding CODAP in another site: Yes, provided you have in mind embedding as an iFrame. There are many examples of this here. If you use the query parameter ?embeddedMode=yes in the url for the iFrame, CODAP will only display the contents of the document.
Hope that helps,
Bill
Hi Kathy,
In addition to using the Main Menu/Open command, they can also set up their screen so they can see both the browser and the file itself in their local file system. Then drag the file into CODAP. Voila!

Hi Joachim,
I was able to follow Jonathan’s suggestion using the DropHTMLTable plugin on the CODAP Data Interactives Plugins page (under utilities). I selected the table text in the PDF and pasted it into the plugin. For some reason I wasn’t able to directly drag into CODAP.
I also discovered a free utility called Tabula that appears to address this need, allowing you to extract tables from PDFs and turn them into a csv. I tried it in a simple case and it worked fine. Let us know if you have any luck with it.

Hello Joachim,
One way is to define an attribute that has the formula
correlation(attribute1,attribute2)
as shown in the attached screenshot. Notice that by dragging the new attribute all the way to the left to promote it, you get a single value that is less confusing than if you left it in the “flat” part of the table.
Another way is to make a scatterplot of the two attributes and, with the ruler icon on its inspector, add a least squares regression line. On the line you will see the value of r-squared.

Hi Asia,
Can you say a bit more about your situation? What are you teaching, and at what level? How do you think CODAP might fit in with your situation?

Regarding the Normal Distribution Sampler: It isn’t a very sophisticated plugin so you have to bring up the case table by hand; i.e. by clicking on the Tables icon and choosing People/Samples. Did you try that? If you did but still didn’t get anything, can you describe in a bit more detail what occurred?
Thanks!
Hello Ann,
I’m so glad you think CODAP is awesome! I agree that it’s useful at the college level, at least lower division. We tend to say it is designed for grades 6-14. And thank you for posting your comment here on the developer forum.
Thank you for sharing the materials you have developed on population growth.
I couldn’t resist taking the population projections and making a CODAP document out of them. A link to a shared copy of it is here.
I’m afraid our project doesn’t have curriculum development resources, but I encourage you to make use of CODAP with your classes. And any questions you have or desires for features, please post here.
