Responses and Knowledge Structures from Taagepera et al. (1997)

Share:

Description

Taagepera et al. (1997) applied knowledge space theory to specific science problems. The density test was administered to 2060 students, the conservation of matter test to 1620 students. A subtest of five items each is included here. The response frequencies were reconstructed from histograms in the paper.

Usage

1

Format

Two lists, each consisting of two components:

density97

a list with components K and N.R for the density test.

matter97

a list with components K and N.R for the conservation of matter test.

K

a state-by-problem indicator matrix representing the hypothetical knowledge structure. An element is one if the problem is contained in the state, and else zero.

N.R

a named numeric vector. The names denote response patterns, the values denote their frequencies.
