Why it works

Data science, working with real data to find patterns, answer questions, and inform decisions, combines statistics, computing, domain knowledge, and critical thinking, and is among the fastest-growing, most in-demand, and most broadly applicable skill areas. Teaching it develops students' ability to collect and clean data, analyze and visualize it, interpret results and draw sound (and appropriately cautious) conclusions, and communicate findings, using authentic, relevant datasets. It is inherently cross-disciplinary (applicable to science, social science, sports, health, and more) and builds both technical skill and data literacy (including recognizing misleading data and claims). Strong teaching uses real data and real questions, emphasizing reasoning and interpretation, not just tools.

The research: CTE and STEM standards; data science education.

The core activity: teach reasoning with real data

Teachers leave with a real-data investigation emphasizing interpretation.

Pick a real question and an authentic dataset.
Teach students to collect/clean, analyze, and visualize the data.
Emphasize interpreting results and drawing sound, cautious conclusions.
Build data literacy (including spotting misleading data) and communication.

Reasoning with real dataData science combines analysis, visualization, and critical interpretation of real data. Use authentic datasets and real questions, emphasizing sound reasoning and interpretation, not just tools.

Facilitator notes

Use real questions and authentic data.
Teach analysis, visualization, and interpretation.
Emphasize sound reasoning and data literacy; communicate findings.

Making charts without reasoning is not data scienceProducing visualizations without sound interpretation and caution misses the point. Teach reasoning with real data, including spotting misleading data.

Adapt it

Elementary and middle: collect, visualize, simple questions, interpret.
High school: clean, analyze, visualize, interpret cautiously, careers.
All settings: real data and questions, reasoning and interpretation.

Common questions

Isn't data science just statistics?

It draws on statistics but also computing, domain knowledge, visualization, and critical interpretation, working with real, often messy data to answer real questions. It is broader and more applied than a statistics course.

What skills does it build?

Collecting and cleaning data, analyzing and visualizing it, interpreting results and drawing cautious conclusions, communicating findings, and data literacy (spotting misleading data). Hugely in-demand and cross-disciplinary.

How do I teach it well?

Use authentic, relevant datasets and real questions, and emphasize reasoning and interpretation, not just tools. The goal is sound thinking with data, not just producing charts.
