  1. 🔗 bit.ly/dsbox-dscwav Three questions that keep me up at night…

    1 What should my students learn? 2 How will my students learn best? 3 What tools will enhance my students’ learning?
  2. 🔗 bit.ly/dsbox-dscwav 1 What should my students learn? 2 How

    will my students learn best? 3 What tools will enhance my students’ learning? Three questions that keep me up at night… Content Pedagogy Infrastructure
  3. 🔗 bit.ly/dsbox-dscwav AUDIENCE I have been teaching with R for

    a while, but I want to update my teaching materials I’m new to teaching with R and need to build up my course materials This teaching slide deck I came across on Twitter is pretty cool, but I have no idea what type of course it belongs in
  4. 🔗 bit.ly/dsbox-dscwav TOPICS Fundamentals of data & data viz, confounding

    variables, Simpson’s paradox + R / RStudio, R Markdown, simple Git Tidy data, data frames vs. summary tables, recoding & transforming, web scraping & iteration + collaboration on GitHub Building & selecting models, visualizing interactions, prediction & validation, inference via simulation Interactive viz & reporting, text analysis, Bayesian inference + communication & dissemination
  5. 🔗 bit.ly/dsbox-dscwav CONTENTS 🖥 48 slide decks 🏄 10 application

    exercises 👩🔬 14 computing labs ✍ 10 homework assignments ✔ 2 take-home exams 📝 1 open-ended project website datasciencebox.org repository 🎥 48 videos 🤹 9 interactive tutorials package dsbox 🤹 9 interactive tutorials
  6. 🔗 bit.ly/dsbox-dscwav DESIGN PRINCIPLES 🎉 cherish day one 👶 skip

    baby steps 🍰 start with cake 🌲 leverage the ecosystem 🥦 hide the veggies
  7. DESIGN PRINCIPLES 🍰 Start with cake ‣ Open today’s demo

    project ‣ Knit the document and discuss the results with your neighbor ‣ Then, change Turkey to a different country, and plot again
  8. DESIGN PRINCIPLES 🍰 Start with cake With great examples, comes

    a great amount of code… but let’s focus on the task at hand… ‣ Open today’s demo project ‣ Knit the document and discuss the results with your neighbor ‣ Then, change Turkey to a different country, and plot again
