Ramadhan, Syahrul; Sumiharsono, Rudy; Mardapi, Djemari; Prasetyo, Zuhdan Kun – International Journal of Instruction, 2020
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…

Sideridis, Georgios D.; Tsaousis, Ioannis; Alamri, Abeer A. – Educational and Psychological Measurement, 2020
The main thesis of the present study is to use the Bayesian structural equation modeling (BSEM) methodology of establishing approximate measurement invariance (A-MI) using data from a national examination in Saudi Arabia as an alternative to not meeting strong invariance criteria. Instead, we illustrate how to account for the absence of…

Istiyono, Edi; Dwandaru, Wipsar Sunu Brams; Lede, Yulita Adelfin; Rahayu, Farida; Nadapdap, Amipa – International Journal of Instruction, 2019
The objective of this study was to develop Physics critical thinking skill test using computerized adaptive test (CAT) based on item response theory (IRT). This research was a development research using 4-D (define, design, develop, and disseminate). The content validity of the items was proven using Aiken's V. The test trial involved 252 students…

Ayene, Mengesha; Kriek, Jeanne; Damtie, Baylie – Physical Review Special Topics - Physics Education Research, 2011
Quantum mechanics is often thought to be a difficult subject to understand, not only in the complexity of its mathematics but also in its conceptual foundation. In this paper we emphasize students' depictions of the uncertainty principle and wave-particle duality of quantum events, phenomena that could serve as a foundation in building an…
