- 中文摘要: The item response theory (IRT) is a well-developed theorem, which can be used to estimate the unidimensional ability of a student precisely. Based on this theory, the construction of parallel test forms can be performed such that the teaching activities can be evaluated precisely. Unfortunately this test construction problem is a combinatorial optimization problem, and now there is no polynominal time algorithm that exists for finding the optimal solution (i.e., minimizing the deviations from the target (parallel) test information function). In this paper, an effective method is proposed for constructing parallel test forms with approximation to the amount of target test information by selecting items from an item bank. The experimental results show that the proposed method can be used to obtain very good results that approximate those obtained using recently proposed approaches. However, our method is much simpler than the other methods, thus, our proposed method significantly reduces the computation time for constructing the parallel test forms. This method will be very useful to educational measurement.
