This study utilizes an analysis of diminishing returns to examine the relationship between sample size and item parameter estimation precision when utilizing the Masters' Partial Credit Model for polytomous items. Item data from the standardization of the Batelle Developmental Inventory, 3rd Edition were used. Each item was scored with a…

This paper presents item-analysis data to illustrate how to identify a set of internally consistent test items that differentiate or discriminate among examinees who are highly proficient and nonproficient on the construct of interest. Suggestions for analyzing the quality of test items are offered as well as a pedagogical approach to augment the…

This study aims to investigate the effect of methods to deal with missing data on item difficulty estimations under different test length conditions and sampling sizes. In this line, a data set including 10, 20 and 40 items with 100 and 5000 sampling size was prepared. Deletion process was applied at the rates of 5%, 10% and 20% under conditions…

This is a descriptive study that assessed the construct validity of the departmentalized test for Grade 11 Literature implemented by PHINMA-University of Pangasinan in three (3) consecutive school years. In the context of this study, construct validity of the departmentalized test (DT) was investigated using twofold measures. The first one is…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades K, 1, and 2 student abilities. The test was administered to 4,535 participating grade K, 1, and 2 students in 66 schools located in 9 public school districts in Florida during spring…

Learning chemistry is a hard task for many secondary school students; thus, students find it tough to score better marks in chemistry. Researchers have identified many reasons and suggested lots of alternatives to overcome difficulties in chemistry. This paper focuses on whether the test item construction has any role in the response pattern of…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades K, 1, and 2 student abilities. The test was administered to 4,486 participating grade K, 1, and 2 students in 67 schools located in 10 public school districts in Florida during fall 2015.…

The least squares distance method (LSDM) was used in a cognitive diagnostic analysis of TIMSS (Trends in International Mathematics and Science Study) items administered to 4,498 8th-grade students from seven geographical regions of Turkey, extending analysis of attributes from content to process and skill attributes. Logit item positions were…

Students often have trouble understanding key biology ideas because they lack an understanding of foundational chemistry ideas. AAAS Project 2061 is collaborating with BSCS in the development a curriculum unit that connects core chemistry and biochemistry ideas in order to help eighth grade students build the conceptual foundation needed for high…

Many people in Spain are studying English in order to find jobs in this country or to migrate as a result of the economic crisis. Language classes, however, are limited in duration and are often not enough to enable students to progress as much as they would like to. Language learners have to spend a considerable amount of time out of class…

This qualitative study examined elementary and middle school students' perceptions of assessment. Individual interviews were conducted with 64 students, with questions focused on their emotional reactions and thinking about classroom and large-scale assessment as related to goal orientation, self-regulation, attributions, and self-efficacy.…

The present report demonstrates the difference between classical test theory (CTT) and item response theory (IRT) approach using an actual test data for chemistry junior high school students. The CTT and IRT were compared across two samples and two forms of test on their item difficulty, internal consistency, and measurement errors. The specific…

This paper describes major concepts related to item analysis for criterion-referenced tests including validity, reliability, item difficulty, and item discrimination, particularly in relation to criterion-referenced tests. The paper discussed how these concepts can be used to revise and improve items and listed suggestions regarding general…
