Windows 10 and updated Chrome worked for me as well.
In addition to Bill’s suggestion above you might also try clearing your browser cache (or opening CODAP in an incognito window).
I was able to import that csv into CODAP using Chrome without issue.
What version of the Chrome browser are you using?
Have you installed any new browser extensions recently?
Is your computer managed by your school? Could they be blocking uploads on Chrome?
Can you add the csv file as an attachment so we can take a look? Just tested a local csv and that worked, so it’s not a general issue with importing data.
Bill if movable values could be captured in the formulas, then one could manipulate the line and see reflections in the formulas automatically updated. Not sure how often a feature like that would be used though.
This doc shows some options. One can calculate a count or calculate a quadrant and then color by quadrant. If you turn on “show measures for selection” in the graph, then clicking on one of the quadrants in the legend will select just those and show a count in the upper right. https://codap.concord.org/releases/latest/static/dg/en/cert/index.html#shared=https%3A%2F%2Fcfm-shared.concord.org%2FhsqIEZxkwpcYCUHSyR35%2Ffile.json
Unfortunately Google Drive does not provide you a direct link to the csv file, so CODAP can’t import using the share URL Google Drive provides.
If you could post to a server that provides public, web-accessible, direct URLs to files then what you are trying to do would work.
Other options using Google Drive:
- On a Google Sheet you can use File->Share->Publish to web. Then the URL you get from that can be given to students which, when clicked on, will initiate a download of a CSV automatically. Then this can be dragged into CODAP. It eliminates one step from them having to download manually.
- You can copy and paste data from a Google Sheet into CODAP. Give them a link to a Google Sheet. Have them select all (command-a or control-a). Then open CODAP and click the Tables button and choose “–new from clipboard–“
Hope that helps.
Well, this is not ideal, but if your range for n is limited enough, you could create one table that calculates the various values for n, and then use that table as a lookup for your own n! function. (The lookup table could be closed, so it would not be visible.)
See example here:
I was blocked from uploading the geojson file so here’s a link to it:
I wanted to learn a bit about the geojson format myself, so in playing around I made a version of the file you sent with the boundaries that have thumbnails.
To make this I ended up doing some combination of formulas in excel and cutting and pasting to make the geojson file from the data that was there. Then I imported the geojson into codap, exported that and pasted the new polygon features with added thumbnail over what was there in the csv.
(Bill I tried to join after importing the geojson but could not get that to work correctly.)
Attached is the geojson file I created as well.
Alison,
Unfortunately, given the list of sensors you described, they are all wired sensors, which won’t work using our software on Chromebooks. To directly connect sensors to work in CODAP on Chromebooks you would need sensors from the Go Direct line of wireless sensors.
There is still a possibility to use Vernier’s own software (perhaps Graphical Analysis) to collect data, export it as a CSV file, and then drag it into CODAP. But that might be too cumbersome, especially for that particular activity you mentioned above.
These links worked for me in multiple browsers, each loading the document within a few seconds. One possibility might be that the school internet filter is now preventing some access to resources being loaded by CODAP. You mentioned that several teachers are reporting this issue. Are they all in the same school? Could be that whitelisting *.concord.org could fix the issue.
The idea of being able to draw regions on an image is intriguing, opening up the possibility for different kinds of infographics…
It worked for me from Excel. I had to move the cursor to the border of the highlighted block of cells so I could get the “hand” cursor for dragging cells around. If I dragged into CODAP I got an imported data set.
For a website to be visible inside CODAP it needs to use a secure connection (i.e. url starts with https). Did you try https://www.stochastik-in-der-schule.de/
Some websites also don’t allow themselves to be framed by another website. In that case there is nothing you can do short of asking the website owner to remove the code that prevents their site form displaying unless it is the top level parent.
