The purpose of this article was to explore the differences in opportunity to learn between higher and lower achieving schools. Additionally, the teachers' perception of Opportunity to Learn (OTL) as it relates to students' achievement were investigated. Teachers were surveyed to investigate any difference in their perceptions of opportunity to…

While achievement gaps have been well-established, much remains to be understood about the manner and extent to which school leadership either increases or decreases student access to opportunity to learn. The current study uses nationally representative samples of U.S. and Flemish students in Grade 4 from the 2011 Trends in International…

Sources of longitudinal achievement data are increasing thanks partially to the expansion of available interim assessments. These tests are often used to monitor the progress of students, classrooms, and schools within and across school years. Yet, few statistical models equipped to approximate the distinctly seasonal patterns in the data exist,…

This Statistics in Brief (SiB) uses data from the 2011 and 2019 Trends in International Mathematics and Science Study (TIMSS), and explores how achievement gaps between high- and low-performing 4th- and 8th-grade students in the U.S. and other education systems have changed over time. Achievement gaps are defined as the differences in scores…

This paper develops models to measure growth in student achievement with a focus on the possibility of differential growth in achievement for low and high-achieving students. We consider a gap-closing model that evaluates the degree to which students in a target group -- students in the bottom quartile of measured achievement -- perform better…

The prevalence of information and communication technologies (ICTs) has brought about profound changes in the field of reading, resulting in a large and rapidly growing number of young digital readers. The article intends to identify key contextual factors that synergistically differentiate high and low performers, high and average performers, and…

This paper provides empirical evidence on students' achievements determinants in Sub-Saharan Africa based on a sample of 26602 students from the ten countries that participated in the PASEC 2014 assessment. By using a two-level hierarchical linear model, I find that learning inequalities are primarily explained by differences in schools'…

This qualitative case study addressed instructional practices used by third-grade teachers teaching at Title I schools to provide strategies to teach higher-order thinking skills in reading comprehension. In Texas, third-grade students were required to take the reconstructed STAAR assessment at the end the 2022-2023 school year. The teachers…

Challenges of teaching Mathematics include inadequate teachers, over reliance on the talk and chalk method of teaching and inadequate use of instructional materials. These resulted in poor academic performance among secondary school students in Osun State, Nigeria. This study therefore determined the effect of locally developed smart learning…

In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in the study reported in this article was that the Frame Factor Theory (FFT) can be used to reveal such mechanisms. Using data from the Swedish TIMSS 2015 (N…

Changepoints are abrupt variations in a sequence of data in statistical inference. In educational and psychological assessments, it is pivotal to properly differentiate examinees' aberrant behaviors from solution behavior to ensure test reliability and validity. In this paper, we propose a sequential Bayesian changepoint detection algorithm to…

This study focuses on a problem of practice at George County Middle School, a 6-8 middle school located in central Kentucky. The achievement gap between English Language learners and non-english language learners continues to grow wider as students' progress through their educational career. As a result, English learners are being…

Over the past three decades Australia has developed an increasingly advanced national system of student assessments, results from which have been used to identify areas of growth, stagnation or decline in student learning. For the most part, trends in different standardised assessments have been considered in isolation. By examining literacy and…

An achievement test was prepared to determine students' caricature reading skills. In the first draft of the achievement test, 32 test items and four choices were prepared for each question. The item analysis of the data obtained from the pre-application was made and the internal consistency coefficient (KR-20) was calculated as 0.67 for the…

This paper identifies OECD's shifting agendas and approaches to education since inception and distinguishes three time periods. Each of these periods reflects shifting geopolitical and economic realities that shaped OECD's priorities and modes of operation. They also demonstrate the adaptive capacity and expansionist nature of OECD's education…
