Description

TIMSS 2007 (Grade 4) dataset with 25 mathematics (dichotomized) items used in Lee, Park and Taylan (2011), Park and Lee (2014) and Park, Xing and Lee (2018). The dataset includes a sample of 698 Austrian students.

Usage

data(data.timss07.G4.lee)
data(data.timss07.G4.py)
data(data.timss07.G4.Qdomains)

Format

• The dataset data.timss07.G4.lee is a list containing dichotomous item responses (data; information on booklet and gender included), the Q-matrix (q.matrix) and descriptions of the skills (skillinfo) used in Lee et al. (2011).

  The format is:

• The dataset data.timss07.G4.py uses the same items as data.timss07.G4.lee but employs a simplified Q-matrix with 7 skills. This Q-matrix was used in Park and Lee (2014) and Park et al. (2018).

  List of 3 $ q.matrix:'data.frame': 25 obs. of 7 variables: ..$ N1: num [1:25] 1 0 1 1 1 0 0 1 0 0 ... ..$ N2: num [1:25] 0 1 1 1 0 0 0 0 0 0 ... ..$ N3: num [1:25] 0 0 0 0 1 0 0 0 0 0 ... ..$ G4: num [1:25] 0 0 0 0 0 0 1 0 0 1 ... ..$ G5: num [1:25] 0 0 0 0 0 1 1 1 1 1 ... ..$ G6: num [1:25] 0 0 0 0 0 1 1 0 0 0 ... ..$ D7: num [1:25] 0 0 0 0 0 0 0 0 0 0 ... $ domains : Named chr [1:3] "Number" "Geometric Shapes and Measures" "Data Display" ..- attr(*, "names")=chr [1:3] "N" "G" "D" $ skills : Named chr [1:7] "Whole Numbers" ... ..- attr(*, "names")=chr [1:7] "N1" "N2" "N3" "G4" ...

• The Q-matrix data.timss07.G4.Qdomains is a simplification of data.timss07.G4.py$q.matrix to 3 domains and involves a simple structure of skills.
