Multilevel Modeling Workshop Materials

 Posted on May 15, 2019  |  2 minutes  |  Erin M. Buchanan

Many thanks to Rutgers University Spanish and Portuguese Department (https://span-port.rutgers.edu/) for asking me to come talk about multilevel models. I enjoyed talking to the group, meeting Twitter friends in real life!, and I am especially impressed by what their department is doing in what is often considered a qualitative science. I used RStudio’s Cloud to share a workspace with all the materials, packages, and other information you might need. I built the slide show using markdown, so that people could watch the slides and/or take their own notes. [Read More]

Intuitions about Grades

 Posted on December 2, 2018  |  6 minutes  |  Erin M. Buchanan

Are my intuitions about grades correct? I was recently talking to a colleague about how utterly terrible my students were doing in my online class this semester and that nearly half were failing the class. We are in our last week of the semester, and I am completely over packing, so I thought I would examine if the judgments I had made about this semester are accurate. First, I took all the times I had taught memory and cognition post Ph. [Read More]

JASP Videos + Guides

 Posted on October 29, 2018  |  2 minutes  |  Erin M. Buchanan

Hey everybody! I am back and finally getting to videos again. I hesistate to say “it’s been crazy!” because I feel like that’s always a thing that academics say, but I will say I’ve had a lot of life going on, and I am finally getting back to a normal amount of crazy. I’ve decided to do some simple videos to start - so I am creating how-to videos to go with our JASP guides we created this summer. [Read More]

Quick and Dirty Categorical lavaan

 Posted on July 5, 2018  |  4 minutes  |  Erin M. Buchanan

I was tagged today on twitter asking about categorical variables in lavaan. I will say I have not done much with categorical predictors either endogenous or exogenous. I did a quick reproducible example of exogenous variables, and I will refer you to the help guide for lavaan here. You will need both the lavaan and psych packages to reproduce this code. Ironically, this data is binary outcome data (the epi dataset in psych), which wasn’t intentional, I just knew it was a good dataset to work with to test how to do exogenous categorical variables.

It’s been nuts, so haven’t left the house much or done much of anything else. [Read More]

Teaching Statement

 Posted on February 17, 2018  |  4 minutes  |  Erin Buchanan

Overview. My approach to teaching centers on the ideas of accessibility, association, and application. As an effective instructor, I strive to ensure that all students are able to orient to and understand material. Often, this process involves formal efforts to reduce barriers to their learning and/or facilitate a stronger grasp of material through association with things they already know. Once students are able to access information, they can begin to understand it and in turn apply it in novel ways. [Read More]
