  2. We define Data Science Workflows broadly, as: "The reproducible and

    transparent ways you do your data analysis" This encompasses: • literate code documents (e.g. Rmarkdown, Notebooks, etc.) • analysis scripts • pipelines • environment management tools • etc. Mike Love Tiffany Timbers
  3. "The reproducible and transparent ways you do your data analysis"

    This encompasses: • literate code documents (e.g. Rmarkdown, Notebooks, etc.) • analysis scripts • pipelines • environment management tools • etc. We define Data Science Workflows broadly, as: I’m going to focus on this as it relates to Teaching and Outreach
  4. What is a case study? https://ia600203.us.archive.org/11/items/cu31924018826713/cu31924018826713.pdf C. C. Langdell Dean

    of Harvard Law School from 1870 to 1895
  5. What is a case study? Before Langdell's tenure, the study

    of law was very technical And students were simply told what the law is. During Langdell’s tenure, he applied the principles of pragmatism to the teaching of law à students were compelled to use their own reasoning powers to understand how the law might apply in a given case.
  6. What is a case study? “Law, considered as a science,

    consists of certain principles or doctrines. To have such a mastery of these … is what constitutes a true lawyer; and hence to acquire that mastery should be the business of every earnest student of law.” – C. C. Langdell C. C. Langdell Dean of Harvard Law School from 1870 to 1895

  10. What is a case study?

  11. Elements of a case study Background: provides context for the

    problem to be solved Problem: a dilemma to be resolved or a decision to be made Supporting information: data, exhibits, interviews, supporting documentation, etc
  12. Characteristics of a good case study Real real-world situations /

    real problems / based on real events / realistic, complex, and contextually rich situations / contemporary / recent / tells a real story Focused on students engages students / student centered / students make choices / active learning Link between theory and practice application of concepts in practice / bridges the gap between theory and practice / make choices about what theory to apply / highlight connections between academic topics and real-world situations / connects the academy and the workplace Ambiguous complex and ambiguous / present unresolved issues, situations, or questions / ”art of managing uncertainty” / without a detailed script / coping with ambiguities
  13. Teaching

  14. Guidelines for Assessment and Instruction in Statistics Education (GAISE) College

    Report 2016 1. Teach statistical thinking. (Teach statistics as an investigative process of problem-solving and decision making). 2. Focus on conceptual understanding. 3. Integrate real data with a context and purpose. 4. Foster active learning. 5. Use technology to explore concepts and analyze data. 6. Use assessments to improve and evaluate student learning.

  21. Incorporating Git/GitHub workflows into data science workflows in the classroom

  23. Describes how to integrate Git/GitHub workflows into statistics courses targeted

    towards students with computational backgrounds
  24. Jacob Fiksel @jfisel1 https://arxiv.org/abs/1811.02021 Describes how to integrate Git/GitHub workflows

    into statistics courses targeted towards students with non-mathematical backgrounds (e.g. public health, sciences) “Using a reproducible workflow in statistics is vital to a complete data analysis, yet for faculty and students with limited computing background, learning version control tools such as Git can be difficult and intimidating. [Here] we outline some of the ways that the Git workflow can be implemented in statistics courses at all levels”
