Researchers design diagnostic assessments to measure students' knowledge structures and processing skills to provide information about their cognitive attribute. The purpose of this study is to determine the instrument's validity and score reliability, as well as to investigate the use of classical test theory to identify item characteristics. The…

Since the development of the technological pedagogical content knowledge (TPACK) framework, researchers have been developing a variety of instruments to measure the TPACK of pre-service and in-service teachers. The task of developing an efficient, reliable, and valid instrument is difficult. Even validated instruments require guidance for…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…

e-Textbooks and e-learning technologies have become ubiquitous in college and university courses as faculty seek out ways to provide more engaging, flexible and customizable learning opportunities for students. However, the same technologies that support learning can serve as a source of frustration. Research on frustration with technology is…

Pupils' attitudes towards technology have been widely discussed for over three decades, but the equally important topic of teachers' attitudes towards technology has not gained similar attention. To address this gap, the technology teachers' attitude towards technology (TTATT) scale was developed and validated by pilot testing with 140 Chinese…

Background: There is an agreement that the methodological quality of randomized trials should be assessed in systematic reviews, but there is a debate on how this should be done. We conducted a construct validation study of the Physiotherapy Evidence Database (PEDro) scale, which is widely used to assess the quality of trials in physical therapy…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

Although the development of critical thinking and chemical literacy is a major goal of science education, the adequate emphasis has not been given to the measurement of both skills. This study reports the development and validation of an integrated assessment instrument to measure students' critical thinking skill and chemical literacy together in…

Working under classical test theory (CTT) and item response theory (IRT) frameworks, this study investigated psychometric properties of the Revised Purdue Spatial Visualization Tests: Visualization of Rotations (Revised PSVT:R). The original version, the PSVT:R was designed by Guay (1976) to measure spatial visualization ability in…

The original "Bayley Scales of Infant Development" (BSID) (Bayley 1969) have been among the most popular measures of performance and aptitude of infants. In the present study the reliability and construct validity of mental and motor scores on the revised Bayley Scales of Infant Development-II (BSID-II) were investigated. A national…

The keylist format (rather than the conventional multiple-choice format) for item presentation provides a machine-scorable surrogate for a truly free-response test. In this format, the examinee is required to think of an answer, look it up in a long ordered list, and enter its number on an answer sheet. The introduction of keylist items into…

As a measure of musical aptitude, a new 90-item Pitch Discrimination Test was developed, and its internal structure was examined. Each of the three sections of the test measures an individual's aptitude for pitch discrimination in a different frequency range using square-wave tones generated by a personal computer. A total of 1,303 examinees,…
