Exceeding Information Targets in Fixed-Form Test Assembly

Autor: Gospodinov, Ivan, Karaibrahimova, Emira, Filipov, Stefan M.

This work studies the assembly of ability estimation test forms (called tests, for short) drawn from an item bank. The goal of fixed-from test assembly is to generate a large number of different tests with information functions that meet a target inf

Report

Autor: Filipov, Stefan M., Gospodinov, Ivan D.

This paper defines constrained functional similarity between 2-D trajectories via minimizing the H1 semi-norm of the difference between the trajectories. An exact general solution is obtained for the case wherein the components of the trajectories ar

Meeting an absolute test information target with optimal number of test items via Grand Canonical Monte Carlo simulation

Autor: F|ilipov, Stefan M., Gospodinov, Ivan D.

This work studies IRT-based Automated Test Assembly (ATA) of multiple test forms (tests) that meet an absolute target information function, i.e. selecting from an item bank only the tests that have information functions that are at a small distance a

Shooting-Projection Method for Two-Point Boundary Value Problems

Autor: Filipov, Stefan M., Gospodinov, Ivan D., Farago, Istvan

This paper presents a novel shooting method for solving two-point boundary value problems for second order ordinary differential equations. The method works as follows: first, a guess for the initial condition is made and an integration of the differ
