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

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.

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.
