Getting started with ‘open science’ through blogging

Through a few different projects and people (such as SIPS and rOpenSci and conversations with friends / colleagues both online and offline), I have been exposed to the idea of open science. I’m actually going to punt for the moment. Here’s a definition that sounds about right to me: Open science is the movement to make scientific research, data and dissemination accessible …

A person-in-context approach to student engagement in science (article in JRST)

Over the past few years, I have worked with Jennifer Schmidt and Patrick Beymer to explore student engagement in science using the Experience Sampling Method (ESM). Most recently, we used what scholars have referred to as a “person-in-context” approach, using both ESM and a person-oriented approach. A figure is helpful for conveying how the person-oriented approach can be used to …

Using MPlus from R with MPlusAutomation

According to the MPlus website, the R package MPlusAutomation serves three purposes: Creating related groups of models Running batches Extracting and tabulating model parameters and test statistics. Because modeling involves comparing related models, (partially) automating these is compelling. It can make it easier to use model results in subsequent analyses and can cut down on copy and pasting …

The R package for person-oriented analysis (prcr) is updated (it’s now version 0.1.4). In particular, it was not clear how to use the profile assignments (i.e., what cluster each response is in) in subsequent analyses. So, the update now returns two different representations of the profile assignments, or which profile is associated with each observation: …

Open datasets for educational use

I’ve been interested in compiling open datasets for educational use. I’m especially interesting in datasets that may be appropriate for K-12 use, so I think it is important the data are a) cleaned and b) possibly relevant / interesting. Here are those I have come across after an initial search: Quandl Data Shop at Carnegie …

Modeling learning: take two

I was thinking last week about modeling learning in terms of an article that argued that different “models” (behavioral, cognitive, social) help to explain different aspects of learning. That motivated me to model what I think learning is — here’s my initial result with an explanation below: Individuals have some motivation for participating in social practices. Social practices as …

Modeling learning

I recently read an article by Bruner on “Models of the learner” which sparked my thinking about what a “model” is and how learning is “modeled” in theories of learning. I found it helpful to think of models of learning as simplified representations of aspects of the theories and how they are related. Behaviorist “models” …
