Raw scores

This file contains data associated with "Building Word-Problem Solving and Working Memory Capacity: A Randomized Controlled Trial Comparing Three Intervention Approaches", a publication in the Journal of Education Psychology (2022), 2022, Vol. 114, No. 7, 1633–1653. Specifically this includes data on: nesting variables, general participant information, pre, post, delayed post on working memory (WM), word-problem solving (WPS), and arithmetic.
See also "Follow-Along Classmates Working Memory, Math, Demographics at Pre Post" dataset for associated typically developing students.

These data provide pre and posttest results from the SMSC study.

This dataset is longitudinal in nature, comprising data from school years (2007/2008-2010/2011) following students in grade 1 to grade 4. Measures were chosen to provide a wide array of both reading and writing measures, encompassing reading and writing skills at the word, sentence, and larger passage or text levels. Participants were tested on all measures once a year, approximately one year apart. Participants were first grade students in the fall of 2007 whose parents consented to participate in the longitudinal study.

This dataset contains information from the Florida Progress Monitoring and Reporting Network (PMRN) linked to the Florida Twin Project twins. Data within this set contains information related to progress monitoring reading data and end of year reading achievement testing, student demographics, and school and teacher clusters for the 2003/2004 to 2013/2014 school years.

This dataset contains measures from the third wave of data collection of the twins' achievement (collected in 2016). Data was collected via parent assessment using instructions sent in the mail.

This dataset contains measures from the second wave of data collection of the twins' achievement (collected in 2014). Data was collected via parent assessment using instructions sent in the mail.

This dataset contains measures from the first wave of data collection of the twins' achievement (collected in 2012). Data was collected via parent assessment using instructions sent in the mail.

This is the Colorado Twin Dataset in Long Format

This data set includes all total scores, demographics, home literacy environment, etc. for Project KIDS. Data are in wide format, with separate variables for each wave of assessments. All 4038 participants are represented in the data. Data are combined from 9 independent RCTs, but the scores have NOT been harmonized, with one exception (i.e., SSRS_IDA) .
