# The art and science of teaching data science (UoE Biology)

Modern statistics is fundamentally a computational discipline, but too often this fact is not reflected in our statistics curricula. With the rise of data science, it has become increasingly clear that students want, expect, and need explicit training in this area of the discipline. Additionally, recent curricular guidelines clearly state that working with data requires extensive computing skills and that statistics students should be fluent in accessing, manipulating, analyzing, and modeling with professional statistical analysis software. In this talk, we introduce the design philosophy behind an introductory data science course, discuss in progress and future research on student learning as well as new directions in assessment and tooling as we scale up the course.

2. ### 2016 GAISE 1. Teach statistical thinking. ‣ Teach statistics as

an investigative process of problem-solving and decision making. Students should not leave their introductory statistics course with the mistaken impression that statistics consists of an unrelated collection of formulas and methods. Rather, students should understand that statistics is a problem-solving and decision making process that is fundamental to scienti fi c inquiry and essential for making sound decisions. ‣ Give students experience with multivariable thinking. We live in a complex world in which the answer to a question often depends on many factors. Students will encounter such situations within their own fi elds of study and everyday lives. We must prepare our students to answer challenging questions that require them to investigate and explore relationships among many variables. Doing so will help them to appreciate the value of statistical thinking and methods. 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 analyse data. 6. Use assessments to improve and evaluate student learning. amstat.org/asa/ fi les/pdfs/GAISE/GaiseCollege_Full.pdf

7. ### a course that satis fi es these four points is

looking more like today’s intro data science courses than (most) intro stats courses but this is not because intro stats is inherently “bad for you” instead it is because it’s time to visit intro stats in light of emergence of data science
