In Practice

1. Visualizing data

Before jumping straight into Google Public Data Explorer with your class, take some time to discuss visualizing data. This could involve looking at infographics on topics that interest your students, playing with interactive visualizations or even getting crafty and creating your own visualizations on posters or on the board. From there the detailed manipulations that Google Public Data Explorer can perform will start making a lot more sense to your students.

2. Reading charts

One of the first steps to working with data is being able to read and comprehend charts and graphs. Start using some of the example datasets and different graph types to help students understand how lines, bars, plots and bubbles can be used to display vast amounts of information in clear and concise ways. The animations that Google Public Data Explorer uses to transition between changes in data can really help students make this connection.

3. Understanding real data

If your students are comfortable reading graphs and charts then it’s time to put their understanding to the test. Choose a relevant dataset from the Google Public Data Explorer collection and give your students some real-life open ended questions to answer. Encourage them to use the data as a starting point for further research. Have them use the charts and graphs to extrapolate and draw conclusions. Their answers should be well thought out and presented explanations of what the data implies, not straight single figures.

4. Data collection and composition

The next step for students, is to start thinking about how they can visualize and use their own data to draw useful and meaningful conclusions. For this, students need to think about how they should be collecting, collating and storing their data to import into tools like Google Public Data Explorer. This could be data from an in-class experiment, from public datasets or even imported from apps and websites they use.

5. Analyzing and sharing your own data

The final step and where you can really begin to utilize the amazing power behind Google Public Data Explorer, is by having your students import their own data. From here students can not only unearth fascinating correlations in their own findings, but they can also opt to make the data public and share it with the world!
