There has been a strong narrative in Australia of falling attainment in high school science, with much of the campaign informed by results from international standardised tests such as Programme for International Student Assessment (PISA), which shows a year-on-year decline in scientific literacy of Australian 15-year-old students. These results…

Science academic achievement is a key construct for examining students' science learning outcomes. While international comparative assessments like TIMSS and PISA have shown high science achievement of Korean middle school students, there is a lack of comprehensive investigation of factors influencing the achievement using domestic data.…

We explore the impact of the language of instruction on academic performance of Arabic-speaking students who are expected to learn mathematics and science in and through a second language (L2). Using as a theoretical background Cummins's (1984) framework relating language proficiency to academic achievement, we provide some insights into the…

The focus on STEM has centered on knowledge use across multiple disciplines. However, there currently exists limited understanding of the relationship between the cognitive practices utilized across these disciplines as a function of performance on standardized assessments. Focusing on science and mathematics, we investigated the direct and…

Although the number of countries conducting large-scale assessments has increased significantly over the past two decades, this has not necessarily led to the effective use of learning assessment data in policy-making and planning. To better understand the reasons for this, the UNESCO International Institute for Educational Planning (IIEP)…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Large-scale learning assessments can be used to generate performance and contextual data on student learning outcomes. They can be national, regional, or international; school based or household based. The UNESCO International Institute for Educational Planning (IIEP-UNESCO) has conducted a qualitative study to explore both how and why learning…

An international survey of geoscience education has been carried out jointly by UNESCO and the International Geoscience Education Organisation (IGEO) to address the question of 'How does school-level Earth science education compare across the globe? The survey gathered data from experts in 51 countries, comprising more than half the global…

Finnish students have been among the world's strongest performers on standardized assessments throughout the past decade. Consequently, educators and scholars are interested in how to explain such results. A common explanation, as seen on social media, is that Finnish educators do not regularly assess their students. This study explores educators'…

New research sheds light on the claim that U.S. students' achievement lags behind that of students worldwide. This research reveals a paradox: While large amounts of U.S. students who take the National Assessment of Educational Progress (NAEP) fail to meet its Proficient benchmarks in reading and math, when students' results on NAEP are…

The aim of the present study is to examine the effect of demographic characteristics of students in Turkey upon their performance in TIMSS, an international assessment exam and Secondary Education Transition Examination which is a national exam (OGS). One of the fields of sciences, biology is taken into account as student performance. As a result…

Has the gap in average standardized test scores between students from high- and low-income families widened, narrowed, or remained stable over the last 3 decades? The question is important both because the achievement gap is measure of how (un)equally educational opportunities are distributed in the US, and because the disparity in educational…

The past thirty years have seen a rapid expansion of testing, exposing students worldwide to tests that are now, more than ever, standardized and linked to high-stakes outcomes. The use of testing as a policy tool has been legitimized within international educational development to measure education quality in the vast majority of countries…

This article reviews the history of intelligence measurement in the Sultanate of Oman, based on different aspects of historical evidence. These intelligence measurements have been used to describe activities of the Omani citizens. Since there is no unique Omani intelligence test, researchers conducted studies to standardize different intelligence…

In this work we examined the content of approximately 950 mathematics questions used in measuring achievement among 4th, 5th and 6th graders in the US in an attempt to determine how the current standardized examinations, which were developed to reflect new national curricular mandates, compared to the old measures used for the same purpose. Using…
