Unit Data is all around us

Year level: F-2 Topic: Explore Data Time: 5 hours

This aspect of digital technologies has strong connections to the Mathematics learning area and can be integrated to make learning more meaningful. The data strand at F-2 can also be taught in alignment with reading when students are expected to construct meaning from text. Text is a form of data. Connections to other relevant learning areas are also indicated where applicable.

Data is all around us in our everyday life and even our own observations inform us. Data can be presented to us as information in the form of numbers such as the time, date, car speed, temperature, or a train timetable. Data can be presented as symbols such as weather icons, visually as pictures or maps, or as text. Often data is presented using a combination of these such as when used to create an infographic. We use the data to make decisions; Am I running late? What will I wear? How do I travel to a certain location? Should I eat this? What ingredients have been used to make this dish?

In Digital Technologies representing data refers to the way data is symbolised, visually treated or provided as audio. For example, at the F-2 level, data about animals may be represented as images of each animal, emotions may be represented as emojis, and weather data may be represented as icons for wind, rain or describing the amount of sunshine. Presentation of data deals with the format in which it may be presented, such as in a table, T-chart or Y-chart, a picture graph or a bar graph.

We may collect data through observations, photography, audio recordings, video recordings, by survey or from other sources. Data often comes to us unorganised so the first step is to sort the data by common characteristics or attributes, then arrange the data to help make sense and look for patterns, and finally present the data visually.
