Project
Description: Mathematical thinking is in high demand in the global market, but approximately six percent of school-age children across the globe experience math difficulties (Shalev, et al., 2000).
Project
Description: The Western Reserve Reading and Math Project (WRRMP) is a NIH funded longitudinal study on child development. The project has collected data annually for 15 years, with data on approximately 450 twin pairs collected during this time. The project has had several focal points throughout its history.
Dataset
Part of Project: The Home Math Environment and Children's Math Achievment: A Meta-Analysis
Description: The data are in long form, with some studies having multiple lines and includes a sample of children ranging from 3.54 to 13.75 years old. The main effect size is the r, correlation coefficient, and the accompanying sample size is also included.
Dataset
Part of Project: Western Reserve Reading and Math Project
Description: This dataset contains all longitudinal data for the entirety of the WRRMP. This includes 10 waves worth of twin data, with extensive reading, math, behavioral, and environmental measures. Due to the twin nature of the data, data is presented as both long and wide, with each twin represented twice within the dataset.
Dataset
Part of Project: Efficacy of the Core Knowledge Language Arts Read-Aloud Program in Kindergarten through First Grade Classrooms
Description: This data set is a wide file that merges all item level kindergarten student data for both studies and all timepoints.
Dataset
Part of Project: Efficacy of the Core Knowledge Language Arts Read-Aloud Program in Kindergarten through First Grade Classrooms
Description: This data set is a wide file that merges all of the CKLA data sets at the kindergarten student level. This dataset is comprised of task level variables from student measures as well as student aggregates of teacher measures. This file includes one case for each student.
Dataset
Part of Project: Efficacy of the Core Knowledge Language Arts Read-Aloud Program in Kindergarten through First Grade Classrooms
Description: This data set is a wide file that merges all of the CKLA data sets at the G1 student level. It focuses on the variables most likely to be analyzed. Although this is a student-level file, we only include student aggregates of teacher measures in this data set due to COVID-19 preventing data collection on G1 students .

Code
Home Math Environment and Children's Math Achievement Meta-Analysis R code using the Metafor package
Part of Project: The Home Math Environment and Children's Math Achievment: A Meta-Analysis
Description: This code was written in R version 3.5.3 using the metafor package (Viechtbauer, 2010). First the dataset is called in, then the variables are converted to the correct formats for analysis, then the escalc() function is used to calculate an overall Fisher's Z effect size, which is then converted to an R correlation coefficient.
