Mixture Modeling for Discipline Based Education Researchers (MM4DBER) is an NSF-funded training grant to support STEM Education scholars in integrating mixture modeling into their research.

---

Day 1 (August 31, 2023): Introductions, training goals, introduction to mixture modeling

Learning Outcomes:

1. Identify why research goals and aims (not research questions) are more appropriate for mixture models
2. Create a first draft of your equity-focused research goals that can be addressed with mixture modeling
3. Identify how the MM4DBERs training goals and opportunities can help you to address your research goals

Synchronous Activity:

• Slide deck here
• Workspace here

Asynchronous Activity:

• Activity 1: Create a draft of your research goals (starting on slide 9 of the Workspace

• Activity 2: Install: R, RStudio, MPlus, MplusAutomation, R-packages

• Install R/Rstudio: HERE you will find a guide to installing both R and RStudio.

• Install Mplus: HERE
• Install MplusAutomation: HERE

• Note: You should have received a copy of Mplus for use during the one-year training (requires a paid license).

• Install packages & practice creating Rproject: Watch these tutorial videos which introduce R & Rstudio and walk through how to install and load packages
• HERE - Intro to R video tutorial (Covered in first 7 minutes)
• HERE - Intro to MplusAutomation video tutorial (Covered in first 12 minutes)

NOTE: It is highly recommended that you watch the full videos before day 5 of pre-training. Especially for those who are learning R/Rstudio.

If you need help, drop into office hours. Book an appointment HERE

Day 3 (September 2, 2023): Introduction to Latent Class Analysis

Learning Outcomes:

1. Construct a path diagram for mixture models
2. Connect research goals and theory to a path diagram

Synchronous Activity:

• Updated Slide deck here
• Workspace here

Asynchronous Activity:

1. Read mixture modeling artice from Day 2, activity 2. Using the workspace slide deck, answer questions related to the article. We will discuss these at the start of day 4.
2. To help with the review of logistic regression, watch these videos:

• Odds Ratio Review Video
• Chi Square Test Review Video
• Conditional Probabilities and Contingency Tables

Day 4 (September 7, 2023): Review of Logistic Regression

Learning Outcomes:

1. Identify why it is relevant to use logistic regression in mixture modeling
2. Understand the relationship between logits, odds ratios, and probabilities in the context of logistic regression
3. Interpret results of logistic regression
4. Identify the importance of multinomial logistic regression in the context of LCA (What is it & why do we care?)

Synchronous Activity:

• Slide deck here
• Fermant et al. (2021) article
• Workspace here

Asynchronous Activity:

• Activity 1: Interpret logistic regression output from Mplus output file - Slide 17 Workspace
• Activity 2: Review videos explaining odds ratios, conditional probabilities, and chi square tests (Optional; as needed) - Slide 29 Workspace
• Video (Multinominal logistic regression, finishing slides we did not get to): Here
• Video - Synchronous activity solution (“Activity 2”; not covered in class): Here

Day 5 (September 11, 2023): R, RStudio and MplusAutomation

Learning Outcomes:

1. Using Mplus software, fellows the basic skeleton of a Mplus input (.inp) syntax, run basic descriptive statistics, and evaluate output (.out)
2. Run descriptive statistics in R using the MplusAutomation package
3. This workshop will cover the creation of R-projects and R markdowns and discuss the benefits of organization of the R workflow.

Preparation:

• Instal R, Mplus, and RStudio
• Watch videos (if you haven’t already): Intro to R , Intro to MplusAutomation

Synchronous Activity:

• Slide deck here
• Workspace here

Asynchronous Activity:

• Activity 1: Practice with R/R Studio, Mplus and MplusAutomation - Slide 3 Workspace
• Activity 2: Identify and share an article on mixture modeling - Slide 5 Workspace

Resources:
