CODAP

Similar to other spreadsheet/graphing programs, CODAP allows students to create data sets and investigate relationships by dragging different "cases" and "attributes" to each axis on a graph. CODAP provides some sample sets to get started and introduces users to the type of investigations that are possible. Teachers or students can input their own data collected from experiments in real-world settings or import data from Google Drive or a local file, making it much easier to share a single set of data with the whole class.

Users can quickly change the data being compared by simply clicking and dragging the headings to the desired axis. There's also the ability to include sliders that let students dynamically change the data to see what effect it has on what they're studying. Students can export their images and graphs to include in projects and presentations for assessment, and CODAP files can be stored locally or saved directly to Google Drive for sharing and collaboration.

Overall, CODAP is a very interesting program that can make learning dynamic if students are given the right questions and problems to solve; with carefully guided questions and varied data sets, students can have a lot of fun exploring data. As a bonus, the sample data sets provided are great for getting ideas flowing on what's possible. CODAP also promotes digital literacy and encourages students to look at data in a number of different ways. If you have data you want to explore, students could gain a lot out of this unique and engaging tool.

That being said, as a program on its own, CODAP can be frustrating for students. They may get lost and overwhelmed with the number of variations and comparisons available to them. The interface itself can also be cluttered at times, especially if you're on a smaller screen like a laptop or tablet (even cutting off required buttons and functions). The way the data is organized into "cases" and "attributes" can also be a bit confusing, as can the way tables are broken down into "parent" and "child" data sets. There were a few issues with selecting and highlighting specific data -- and then switching the selections -- as well. When a graph is initially created, random data is selected and provided in an unlabeled and unorganized scatter plot, which may be confusing for students until they get used to it. This means that CODAP relies a lot on the teacher to create authentic learning experiences and provide support for students.
