Project
Description: There is a growing concern about the influence of math anxiety on achievement outcomes and an individual’s potential for success. In response, many studies have investigated the effects of math anxiety on math ability and math outcomes in a variety of mathematics classes and at an assortment of grade levels.
Project
Description: The National Project on Achievement in Twins (NatPAT) is funded by the National Institutes of Health (grant number HD052120).
Project
Description: There is a growing concern about international reports citing the US student population is falling behind in STEM related outcomes.
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: We sought to understand the speech and language skills of children with nonsyndromic cleft palate with or without cleft lip (NSCP/L) by meta-analyzing results of the literature.
Dataset
Part of Project: National Project on Achievement in Twins
Description: This is the survey that was sent to NatPAT caregivers in mid-summer 2021, focused on COVID-19 pandemic impacts on their family.
Dataset
Part of Project: Home Math Environment Study
Description: A final sample of 339 parents of children aged 3 through 8 drawn from Mechanical Turk answered a questionnaire online.
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: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data are from our third meta-analysis project. The speech-vocabulary analysis represented eight samples and the speech-mlu analysis represented four samples. The ages ranged from 18-months to 39-months.
Dataset
Part of Project: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data represent effect sizes comparing children with NSCP/L to non-cleft peers. There are 241 effect sizes from 31 studies. Children's ages ranged from 13-months to 104-months (8;7). The data are in long format as there were multiple effect sizes extracted per study.
Dataset
Part of Project: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data are descriptive codes for the studies included in the meta-analysis. There are 31 studies. Data are presented in wide format. There are 34 variables.
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.
