The purpose of this study is to identify and assess the difficulties experienced by the 11th grade students regarding generating, interpreting and comparing scatter plots. The study was carried out with 40 students-enrolled in 11th grade. The difficulties of students were identified through an achievement test on generating, interpreting, and…

Educational research is ubiquitous; however, agreement on best practices is not. Although parents, teachers, students, and communities have a vested interest in students' success, varying practices of what is taught, how it is taught, and to whom it is taught are still debated. This study expands upon work done by Dr. Scott Wurdinger and Dr. Ron…

This study explored the impact of the 95 Phonics Core Program® (95 PCP) on student literacy achievement across third graders who started the school year at different ability levels. The primary focus of this report was to investigate the relationship between changes in phonics scores with the beginning and end-of-year i-Ready® assessments and…

This paper explores how the OECD acts a broker of knowledge-making in the development of PISA, the most widely known International Large-Scale Assessment. Drawing on the work of Bandola-Gill, Grek, and Tichenor (2022) and analysing empirical data gathered through interviews with OECD staff and PISA contractors and experts, the paper analyses how…

This qualitative multi-site case study explores the self-identified traits of four Philadelphia schools that demonstrate growth in grade four proficiency on the Math Pennsylvania System of State Assessment (PSSA). Obtained proficiency/advanced scores on the PSSA show a drop from third to fourth grade cohorts during 2017, 2018, and 2019. In…

Brazil's education system lags behind international standards, with two-fifths of students scoring below the minimum level of proficiency in mathematics, science, and reading. Thus, this study combined machine learning with traditional statistics to identify the most important predictors and to interpret their effects on proficiency in the PISA…

This article explores the limitations of traditional maximum performance tests in psychological assessments within educational settings, highlighting the need for efficiency assessments to better understand students' real-world capabilities. While maximum performance tests like IQ and achievement tests reveal peak abilities under optimal…

The increasing concerns of the impact of the Programmes for International Student Assessment (PISA) on education policymaking along with its global reach call for the need of evaluating PISA's impact on student learning. However, most extant studies focus on arguing its impact at the policy level, without taking a further look into it at the local…

This article examines the effects of education system types and characteristics on changes in the distributions of literacy and numeracy skills during the upper secondary phase of education and training. Whereas there is a substantial literature on system effects on skills during the primary and lower secondary phases of education, much less has…

Empirical research on teachers' professional knowledge is mostly conducted worldwide with reference to the construct 'pedagogical content knowledge' (PCK) introduced by Lee S. Shulman. In the 'Consensus Model' (CM) and the 'Refined Consensus Model' (RCM), PCK was further developed and differentiated. Nevertheless, neither PCK nor CM and RCM…

This study aims to apply the differential item functioning (DIF) technique with the deterministic inputs, noisy "and" gate (DINA) model to validate the mathematics construct and diagnostic attribute profiles across American and Singaporean students. Even with the same ability level, every single item is expected to show uniform DIF…

Higher vocational education has been on a trajectory of rapid development. However, the challenge of fostering effective learning in students persists. In response to this, a study was undertaken to explore the impact of an optimized model of SPOC-based blended learning (SPOC-BL) on student presence, learning satisfaction, learning motivation, and…

Bias assessment (systematic errors) is fundamental in industry and service laboratories, where reliable results must be obtained to give correct answers to specific problems. Therefore, knowledge and practice in quality methodologies is of fundamental importance for students. Unfortunately, laboratory lessons often focus on connecting theory and…

Like most other states, Missouri uses assessments intended to measure whether students are on a pathway to "college and career readiness." The state longitudinal data system now has the capacity to directly test that claim. We make use of 8th-grade assessment (MAP) scores in Math, Science, and Communication Arts for roughly 260,000…

The purpose of this study was to examine the relationship between the Measures of Academic Progress (MAP) reading Rasch unIT (RIT) score and State of Texas Assessment of Academic Readiness (STAAR) and Texas English Language Proficiency Assessment System (TELPAS) reading achievement among English learners in Grades 8 and 9. The study also…
