SWMD Data Subset

Description

A subset of the COOL5-18 data (see below) with scores of 651 pupils nested in 30 classes on the 7-item Schaal Welbevinden Met Docenten [Scale Well-Being With Teachers] (Peetsma, et al., 2001; Zijsling, et al., 2017). See attributes(SWMD) for the original item labels and content. R-code to get this subsample is available as online supplement to Koopman et al. (in press a).

Usage

data(SWMD)

Format

A 651 by 8 data frame containing integers. The first column reflects a classroom indicator, the remaining columns the 7 items, see colnames(SWMD).

Details

Each item has five ordered answer categories from not true at all (score 0) to completely true (score 4).

Item	Short	Content
Item1	lv_wdo1	The teachers usually know how I feel
Item2	lv_wdo2	I can talk about problems with the teachers
Item3	lv_wdo3	If I feel unhappy, I can talk to the teachers about it
Item4	lv_wdo4	I feel at ease with the teachers
Item5	lv_wdo5	The teachers understand me
Item6	lv_wdo6	I have good contact with the teachers
Item7	lv_wdo7	I would prefer to have other teachers (inversely coded)

The items were translated from Dutch. For the original items, see p. 79 in Zijsling et al. (2017). The scores on these items plus seven additional items are available in dataset SWMDK.
