This week while I have been at Concord Consortium in San Francisco I have spent much of my time making videos of recent activities that use CODAP. All of these activities I have been exploring with teachers and students in the work that I do.
Some of the earlier posts were about how to use CODAP:
This video explores a teaching and learning idea for introducing early ideas of median. For New Zealand teachers this would be an activity I would do with curriculum level 3/4 students as they start to explore quantitative data and are looking for a signal as to the middle of the data that they have. CODAP allows us to put in a movable line and using counts it can be moved until about half the data is sitting on each side. I expand this to looking at the middle 50% of the data values and give examples of how to describe this. As this is aimed at curriculum level 3/4 the examples describe the whole group (Kowhai Whanau Group).
If you want to explore the data set used in the video you can get your own CODAP document to work on by clicking here. The data set used is a made-up data set using a random sample of students from CensusAtSchool.
Great discovery today when I went into the random sampler on Census At School, I found that the 2019 data base is there ready to use. Big shout out to the team at Census At School and to all the teachers and their students who participated in the census. Without all of the students there would be no data base, the teachers make this possible.
To find the database go to https://new.censusatschool.org.nz/explore/
Select download or explore a sample to see the new random sampler page which allows you to select the variables to explore without having to download and then tidy up the file before sharing.
Spending the week at Concord Consortium, home of CODAP, https://codap.concord.org/ . My challenge this week is to create short screen cast videos of some of the guides I have made for teaching aspects of statistics and probability using CODAP as a tool to support the teaching and learning.
