The analysis of the Test Instruments' quality is a crucial thing needs to be conducted. The test instruments made by teachers must fulfil the requirements (validity, reliability, and standard error of measurement) until the measurement result obtained can describe the students' actual abilities. This research aims to analyse the content validity…

The present study aimed to develop a measurement instrument to determine the perceptions of middle school students on their teachers' behavior. The draft scale, developed as a result of the review of the relevant literature, collection of expert views and a pilot scheme, was applied to the students attending different grades in state middle…

Team teaching is a teaching model in which teachers work collaboratively in the preparation, teaching and evaluation of a course. Literature suggests that team teaching potentially provides rich and varied lessons, increased support and learning gains. However, team teaching possibly also could cause some confusion. To support the implementation…

Learning in blended environments has become a ubiquitous part of student experience in tertiary education worldwide. Although students' perceptions of learning environments are a key element in the learning process, there is a dearth of valid instruments to assess students' perceptions in blended contexts. This study described the initial…

The aim of the study is to develop a valid and reliable scale in order to determine the ideational and social contribution of art to politics. The 5 point likert scale was applied to a total of 891 university students studying in different departments of a state university. As a result of exploratory factor analysis (EFA) and confirmatory factor…

Marczewski (2015) has introduced a new classification model for different user types. Tondello et al. (2016) developed and later revised (Tondello et al., 2019) "The Gamification User Types Hexad Scale" based on this model. The aim of this study is to adapt this scale into Turkish. The validity and reliability study of the scale was…

Several school districts in Georgia use two teacher-administered diagnostic assessments of student knowledge of mathematics as part of their multi-tiered system of support in grades K-8: the Global Strategy Stage (GloSS; New Zealand Ministry of Education, 2012) and the Individual Knowledge Assessment of Number (IKAN; New Zealand Ministry of…

This document are the appendixes for the report, "The Reliability and Consequential Validity of Two Teacher-Administered Student Mathematics Diagnostic Assessments." Rather than relying on occasional testimonials from the field, decisions about using diagnostic assessments across the state should be based on psychometric data from an…

Teachers need to assess their students' current level of mathematical understanding to provide appropriate interventions for students who are struggling. Several school districts in Georgia currently use two assessments for this purpose--the Global Strategy Stage (GloSS) and the Individual Knowledge Assessment of Number (IKAN). The IKAN is…
