CV: Sale Items vs. Research Plan

Karen Kelsky writes about the importance of identifying a research plan and building your CV around this plan in her book The Professor is In: The Essential Guide to Turning Your Ph.D. into a Job. A reader once wrote to explain: During my years as a tenure track assistant professor, I went about publishing and doing research the way I do the grocery shopping: concentrating on the sale items like conferences, book reviews, on-line collaborations, i.

Student Awards! So Proud!

On April 26, 2019, two of my Statistics Education graduate students, Chelsey Legacy and Vimal Rao, were given awards during the annual Psychological Foundations and QME Awards and Recognition Ceremony. Chelsey Legacy (first row; right) was awarded the Graduate Student Teaching Award for her incredible work in the EPsy 3264 classroom. Vimal Rao (second row; second from right) was awarded the Graduate Student Leadership Award for his work in building community.

CV Tips

My colleague Joseph Rios and I helped organize a monthly reading and seminar series, QME and Friends Read, for interested graduate students in our program. In March, we hosted a seminar on the Curriculum Vitae, or CV. In preparing for that seminar, I looked through many faculty and student CVs. I also read many blog posts, and scholarly work about putting together a CV. Based on all of this and my own expereiences and advice given to me, I decided to put together a post (maybe multiple posts) that includes some suggestions for compiling a CV.

Computing in the '60s

My dad was a mathematics teacher at Sartell High School and was also really into computing and programming. I remember learning BASIC with him on our Apple IIe and also programming our TI-99/4A. (To save a program on the TI, we had to hook up an external tape recorder and write to a cassette tape. Then to run the program, you played the tape!) Old issues of Byte, Compute, Family Computing (check out the 1982 TV ad below), and other magazines and educational trades were stacked a mile-high in our living room; many providing the outlines of a program to create some graphical spectacle (e.

Deprecating Statistical Significance: Toward Better Science

On Friday April 26, 2019 I gave an invited talk to the Department of Speech-Language-Hearing Sciences in their Pro-Sem series. These are really neat as they are organized by the graduate students. This is the third one of these I have given over the years and each is a treat. In this talk I spoke about the ASA’s recent call for the deprecation of “statistical significance” and all its related variants (e.
