Our team is writing a new course: Explorations in Data Science– in collaboration with Google. It will introduce students to the main ideas in data science through free tools such as Google Sheets, Python, Data Commons and Tableau. Students will learn to be data explorers in project-based units, through which they will develop their understanding of data analysis, sampling, correlation/causation, bias and uncertainty, probability, modeling with data, making and evaluating data-based arguments, the power of data in society, and more! At the end of the course students will have a portfolio of their data science work to showcase their newly developed abilities. The curriculum will be adaptable so that teachers can bring in datasets or use what is provided to find datasets most relevant to their students. We will apply for A-G approval of the course, so it could be taken as an alternative to algebra 2, or in addition to algebra 2. It could lead to a pathway in calculus, statistics, data science, other STEM or humanities subjects.
