In this study, the extent to wording effects impact structure and factor loadings, internal consistency and measurement invariance was outlined. The modified form, which includes items that semantically reversed, explains %21.5 more variance than the original form. Also, reversed items' factor loadings are higher. As a result of CFA, indexes…

This study aimed to develop a test to measure university students' spatial thinking skills. The research was conducted using a survey design, with a sample of 260 undergraduate students from geography teaching and geography departments. GIS software was used to incorporate maps and satellite images, enhancing the spatial representation in the…

This study aimed to examine the effects of reverse items created with different strategies on psychometric properties and respondents' scale scores. To this end, three versions of a 10-item scale in the research were developed: 10 positive items were integrated in the first form (Form-P) and five positive and five reverse items in the other two…

In this study, the Mathematical Knowledge for Teaching-Elementary Patterns Functions and Algebra-Content Knowledge (MKT-PFA) test, originally developed in English as part of the "Learning Mathematics for Teaching Project" at Michigan University, was adapted into Turkish. The test comprises two equivalent forms, A and B, each translated…

The aim of this study is to examine the validity, reliability, and responsiveness of the Turkish version of the Adolescent Health Promotion-Short Form (AHP-SF). This cross-sectional study was completed with 1483 students. Confirmatory factor analysis (CFA) supported the construct validity of the scale, demonstrating a good model fit with…

This study was conducted to develop a measurement tool to achieve epilepsy self-management in teachers and examine its Turkish psychometric properties. This descriptive, comparative, correlational, and methodological study was conducted between May and August 2022 with 346 teachers between the ages of 24 and 67 working in public schools selected…

This study aimed to develop a useful test to measure university students' spatial abilities validly and reliably. Following a sequential explanatory mixed methods research design, first, qualitative methods were used to develop the trial items for the test; next, the psychometric properties of the test were analyzed through quantitative methods…

This study aims to develop a new spatial visualization test (SVT) for second grade primary school students. The study employed the survey design, and the test was developed in accordance with the test development steps. According to the findings obtained as a result of the pilot study, the items were generally high difficulty levels, and they were…

This study aims to compare the G and Phi coefficients as estimated by D studies for a measurement tool with the G and Phi coefficients obtained from real cases in which items of differing difficulty levels were added and also to determine the conditions under which the D studies estimated reliability coefficients closer to reality. The study group…

Achievement tests are among the most widely used data collection tools to measure the knowledge and skill levels of individuals. For this reason, the existence of valid and reliable achievement tests that can perfectly reveal the competencies that a person should have in any discipline is of great importance. The purpose of this research is to…

In this study, it was aimed to develop an achievement test taking into account the subject acquisitions of the sound and properties unit in the sixth-grade science course. In the test development phase, firstly, literature review for the study was conducted. Then, 30 multiple choice questions in align with the subject acquisition in the 2018…

Curriculum adaptation portrays the way teachers 'tweak' the curriculum. The findings of related studies are based solely on qualitative data, and there is no instrument that can determine curriculum adaptation patterns. Based on this gap, the aim of this study is to develop the Curriculum Adaptation Patterns Scale (CAPS). After examining the…

Tests are designed as an integral part of the teaching process, necessarily including stakeholders from the onset of preparations to grade allocation, the administration of the test, and the interpretation of the results. The process commences with selecting content to evaluate, deciding upon the skills to be tested, and to meet course objectives…

It has become a critical question what the reliability level would be when open-ended questions are used in large-scale selection tests. One of the aims of the present study is to determine what the reliability would be in the event that the answers given by test-takers are scored by experts when open-ended short answer questions are used in…

The purpose of this research is to develop a scale to determine teachers' self-efficacy levels regarding differentiated instruction. To create the item pool, the first 61 item draft form was prepared. This draft form was submitted to the opinion of experts from different fields and necessary corrections were made. Before starting the analysis…
