In this study, whether item position effects lead to DIF in the condition where different test booklets are used was investigated. To do this the methods of Lord's chi-square and Raju's unsigned area with the 3PL model under with and without item purification were used. When the performance of the methods was compared, it was revealed that…

Sources of longitudinal achievement data are increasing thanks partially to the expansion of available interim assessments. These tests are often used to monitor the progress of students, classrooms, and schools within and across school years. Yet, few statistical models equipped to approximate the distinctly seasonal patterns in the data exist,…

Validity is one of the psychometric properties of the achievement tests. To determine the validity, one of the examination is item bias studies, which are based on differential item functioning (DIF) analyses and field experts' opinion. In this study, field experts were asked to estimate the DIF levels of the items to compare the estimations…

We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…

In the present study, two types of curriculum-based measurement (CBM) tools in science, Vocabulary Matching (VM) and Statement Verification for Science (SV-S), a modified Sentence Verification Technique, were compared. Specifically, this study aimed to determine whether the format of information presented (i.e., SV-S vs. VM) produces differences…

The purpose of this quasi-experimental study was to see if an intensive nine-week (55 min per day) remedial Math Connection (MC) class for 67 suburban, eighth grade…

Research shows a math achievement gap for at-risk and economically-disadvantaged students in the United States. To address this issue, a Texas school district implemented a 90-minute math block-scheduling program with 8th grade students. Shaped by the academic learning time and social justice theories, the purpose of this quantitative program…

The aim of this study is to determine how the TIMSS mathematics success of the 8th grade students differentiates according to the school type, gender, mathematics report mark, parents' education level, cognitive domains and cognitive domains by gender. Relational survey method was used in the study. Six-hundred fifty two 8th grade students…

The relationship between reading skills in earlier grades and achieving "Proficiency" on the National Assessment of Educational Progress (NAEP) grade 8 reading assessment was examined by establishing a statistical link between NAEP and the Early Childhood Longitudinal Study (ECLS) grade 8 reading assessments using data from a common…

This study investigated the relationship between listening comprehension and reading comprehension to determine if environmental factors might be contributing to a possible change in the equalization age for these two comprehension modalities from what was theorized by Thomas Sticht. The study employed a counterbalanced design to measure the…

It is important for students to learn concepts and using them for solving problems and further learning. Within this respect, the purpose of this study is to investigate students' abilities to apply science concepts that they have learned from Science-Technology-Society based approach or textbook oriented instruction. Current study is based on…

Algebra is an area of pressing national concern around issues of equity and access in education. Recent theories and research suggest that personalization of instruction can allow students to activate their funds of knowledge and can elicit interest in the content to be learned. This paper examines the results of a large-scale teaching experiment…
