learningtower

R-CMD-check

The goal of learningtower is to provide a user-friendly R package to provide easy access to a subset of variables from PISA data collected from the OECD. Version 1.1.0 of this package provides the data for the years 2000 - 2022. The survey data is published every three years. This is an excellent real world dataset for data exploring, data visualising and statistical computations.

What is the PISA dataset?

The Programme for International Student Assessment (PISA) is an international assessment measuring student performance in reading, mathematical and scientific literacy.

PISA assesses the extent to which 15-year-old students have acquired some of the knowledge and skills that are essential for full participation in society, and how well they are prepared for lifelong learning in the areas of reading, mathematical and scientific literacy.

In 2022, PISA involved 79 countries and 600,000+ students worldwide.

Installation

You can install the learningtower package from CRAN with:

install.packages("learningtower")

To install the development version of learningtower from GitHub use:

devtools::install_github("kevinwang09/learningtower")

Data Description

The learningtower gives access to a subset of variables from PISA data originally collected and are available from OECD, collected on a three year basis.

The learningtower package contains mainly three datasets:

This provides us with information about the students scores in mathematics, reading and science, their school details, and which country they are from. The data provided in this package is a cleaned version of the full published PISA organisation, with reproducible code available in this repository.

The number of entries for the student and school data are shown below.

Year Number of Students Number of Schools
2000 127,236 8,526
2003 276,165 10,274
2006 398,750 14,365
2009 515,958 18,641
2012 480,174 18,139
2015 519,334 17,908
2018 612,004 21,903
2022 613,744 21,629

Student Dataset

The student dataset comprises of the scores from the triennial testing of 15-year-olds worldwide. In addition, this dataset contains interesting information on their parents qualifications, family wealth, gender, and possession of computers, internet, cars, books, rooms, desks, and similar other variables.

The full dataset is approximately 50MB in size, which is much larger than the CRAN’s allowed package size limit. As the result, the package itself only includes a random 50 rows from the 38 OECD countries, for each of the survey years. i.e. student_subset_2000, student_subset_2003 etc.

The student subset dataset can be loaded easily. See ?student for detailed information on the measured variables.

library(learningtower)

data(student_subset_2018)
dim(student_subset_2018)
#> [1] 1900   22

The entire student data can be downloaded using the load_student function.

#load the entire student data for a single year
student_data_2018 <- load_student(2018)

#load the entire student data for two of the years (2012, 2018)
student_data_2012_2018 <- load_student(c(2012, 2018))

#load the entire student data
student_data_all <- load_student("all")

Note that because of changing data specification over the survery years, not all variables were measured consistently across the years.

School Dataset

The school dataset comprises school weight and other information such as the funding distribution of the schools, whether the school is private or public, the enrollment of boys and girls, the school size, and similar other characteristics of interest of different schools these 15-year-olds attend throughout the world.

# loading the school data
data(school)

See ?school for more information on the different variables present in the the school dataset.

Countrycode Dataset

The countrycode dataset contains mapping of the country ISO code to the country name. More information on the participating countries can be found here.

# loading the countrycode data
data(countrycode)
head(countrycode)
#> # A tibble: 6 × 2
#>   country country_name
#>   <chr>   <chr>       
#> 1 AZE     Azerbaijan  
#> 2 ARG     Argentina   
#> 3 AUS     Australia   
#> 4 AUT     Austria     
#> 5 BEL     Belgium     
#> 6 BRA     Brazil
Notes on countries

See ?countrycode for more detailed information on the countries that participated in the PISA experiment.

Exploring the data

In the plot shown below, shows the weighted mean of mathematics scores of these 15 year old students for a few selected countries over the available years.
