An experimental science curriculum for primary school was introduced in Croatia for the 1st time in the 2023/24 school year. This is taking place against the backdrop of a shortage of teachers from various science subjects, especially physics. They are increasingly being replaced by non-professional teachers, often those with a Master of Primary…

We examine whether and how teachers' major fields in college affect students' achievement, exploiting within-student variation across subfields in natural science (i.e. physics, chemistry, biology, and Earth science). Using middle-school students' data from the TIMSS and controlling for student-teacher fixed effects, we find that teachers improve…

The participation of countries in various international large-scale assessments (ILSA) is motivated by different factors. In recent years however, there has been a growing popularity and importance placed on the results of ILSA. Recognising the significance of ILSA as a valuable source of feedback for enhancing the basic education system, the…

Teaching science concepts for conceptual understanding has its challenges. Promoting conceptual change in the science classroom can be difficult because most concepts are complicated and counter-intuitive. This dissertation research aimed to determine the effect of teaching for conceptual understanding models on pre-service teachers' conceptual…

The knowledge, skills and attitudes of prospective pre-school teacher towards science education enable more effective classroom practices and science teaching. Teaching scientific processes at an early age affects students' attitudes towards science in the coming years. In this context, this study was designed to examine the relationship between…

We set out to address the question--what does it mean for educational knowledge to be 'powerful'? We compare the Anglo tradition of curriculum studies with the "Didaktik" tradition through the lens of an analysis of curriculum structure in postgraduate courses in South African universities rooted in either the Anglo or…

A wide range of reforms to improve the teaching capacities of pre-service and in-service teachers have been carried out in Kosovo. In assessing the success of these previous interventions, large-scale assessment data is invaluable. In 2019, 4754 students from 145 schools participated in the TIMSS assessment. Results reveal that student's…

Assessment and evaluation have always been an integral part of educational process. Quality and purposeful assessment can assist in students' learning and their achievement. While there has been a rapid growth in international, standardized student assessments in the past few decades, a large number of education systems participating in these…

Saudi students' science academic performance has declined as evidenced by (TIMSS). Saudi science teachers are characterized as using the lecture format without considering individual student differences and failing to provide differentiated Method (DM). This paper reports on an effort to help female Saudi pre-service science teachers (PSST)…

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'…

Adolescent girls more often than boys expect higher education in nearly all 50 education systems in TIMSS 2011, before and after controls for effects of educational achievement, education-conducive family resources, and "liking school." At a macrolevel, this gender disparity is moderately correlated with the gender disparity in…

This report provides a portrait of K-12 science, technology, engineering, and mathematics (STEM) education in the United States. It examines pre-college mathematics and science learning and how that learning affects postsecondary and career outcomes. It also compares U.S. student performance with that of other nations. Data sources include the…

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 aim of this study is to examine preservice science teachers' skills of formulating hypotheses and identifying variables. The research has a phenomenological research design. The data was gathered qualitatively. In this study, preservice science teachers were first given two scenarios (Scenario-1 & Scenario-2) containing two different…

This is the revised edition of the 2023 "Report on the Condition of Education," which is a congressionally mandated annual report from the National Center for Education Statistics (NCES). Using the most recent data available (at the time this report was written) from NCES and other sources, the report contains key indicators on the…
