#### Currently teaching

In Fall 2017 I am teaching Math 019: Fundamentals of Calculus I.

#### Teaching materials

Over the years I have created some teaching-related materials.

- At Stanford I worked on developing what was then Stanford's Precalculus Resource Portal, developed under the supervision of Rafe Mazzeo. The aim of this project was to become a comprehensive website collecting every precalculus resource offered by Stanford across all departments and organizations. Since I left, the project has moved to Stanford's Canvas site, where it is only available to Stanford students.

The only parts still publicly available (as of this writing) are a collection of YouTube videos on various precalculus topics that I wrote and recorded myself. A subset of these form a structured online mini-course on trigonometry, which is also still available, and contains videos I recorded, supplementary videos from Khan Academy, and exercises selected from Khan Academy so that students can practice the skills they have just learned.

As part of my work on the Stanford Precalculus Resource Portal, I also created in 2013 an online precalculus learning tool which is based on the software ALEKS. That is unfortunately no longer available but I would be happy to share my insights if anyone is interested in doing something similar.

The website and its materials were created with the financial support of the Vice-Provost for Undergraduate Education at Stanford University. - At UW-Madison I wrote handout on designing course policies. This document accompanied my hour-long workshop at the Fall 2009 Letters and Science Teaching Assistant Training Program on the same subject. It was created with the financial support of the College of Letters and Science at the University of Wisconsin in Madison.
- At UW-Madison I also wrote study skills handout for students taking calculus. Half of the material is specific to UW-Madison, but the rest applies to any math class an undergraduate might take. This document was created with the financial support of the Wisconsin Emerging Scholars Program at the University of Wisconsin in Madison.

#### Past teaching

##### At UVM

In the past I have taught:

Math 255: Elementary Number Theory (Spring 2016). All course materials were posted on Blackboard. |

Math 124: Linear Algebra (Fall 2016) |

Math 255: Elementary Number Theory (Spring 2017) |

##### At Stanford

For three years I was one of the instructors and coordinators for the first-year univariate calculus sequence Math 19 (fall), Math 20 (winter) and Math 21 (spring).

Stanford maintains and archives the course websites for all courses I have taught there, except for Math 20 in Winter 2014 because it was archived incorrectly on our end.

Math 19 | Math 20 | Math 21 |
---|---|---|

Math 19, Fall 2012 | Math 20, Winter 2013 | Math 21, Spring 2013 |

Math 19, Fall 2013 | This page is unavailable | Math 21, Spring 2014 |

Math 19, Fall 2014 | Math 20, Winter 2015 | Math 21, Spring 2015 |

##### At UW-Madison

Between 2010 and 2012, at UW-Madison I was the TA coordinator and instructor for Math 101: Intermediate Algebra for four semesters, in addition to sitting on the Pre-Calculus Sequence Redesign Committee from 2009 to 2012 (where in particular we redesigned Math 101). In Spring and Fall 2010 we used the software ALEKS. In Fall 2011 and Spring 2012 we used the software MyMathLab, which is the software we ended up settling on for the pre-calculus portion of WisCEL. In the middle, in Spring 2011, we used the software Hawkes, and I worked with it a little bit, even though I was not an instructor.

In Spring 2011 I was the instructor for Math 130: Mathematics for Teaching: Numbers and Operations, Lecture 2. Here is the syllabus for the class, and below are all of the worksheets, homework sets, and various handouts from that semester.
