In web-oriented e-learning systems, the final assessment θ for the answer to the test
item includes, as a rule, only comparison of the user’s final answer (Rybanov, A.A.,
2006b) (Figure: 1, step 4) with the reference answer (Figure: 2) and is calculated
according to the formula:
θ = β·δ , (1)
where β䌜(0;1] - is the test item's difficulty measure; δ - is degree of conformity of the
test item answer to the reference answer.
