Item response theory (IRT) has so many advantages than its precedent Classical Test Theory (CTT) such as non-changing item parameters, ability parameter estimations free from the items. However, in order to get these advantages, some assumptions should be met and they are; unidimensionality, normality and local independence. However, it is not…

This study offers curriculum developers, teachers, and science education researchers a fine-grained profile on strengths and weaknesses in specific science domains and topics. The study involved a representative sample of 3844 Norwegian pupils in grade 8. Their responses on 216 TIMSS items in 18 topics from 4 science domains were modelled in a…

The study is designed to examine the predictive power of Saudi-admission criteria for student performance in an introductory biology course. It focuses on the second semester at King Saud bin Abdulaziz University for Health Sciences. The study addresses whether the General Aptitude test (GAT), the Scholastic Achievement Admission Test (SAAT), and…

This paper describes pedagogical efforts implemented to promote significant learning in a computational chemistry course. The taxonomy of significant learning advanced by Fink (2013) is used as a framework to discuss the results. Fink identifies six categories of learning: foundational, application, integration, human dimension, caring, and…

Federal law requires that, at a minimum, states assess high school students at least once in English language arts/literacy (ELA), mathematics, and science; these results are used for school accountability. With states' recent transitions to new assessments and accountability systems, Achieve wanted to know more about how these varied assessments,…

Throughout the country, state assessments in reading, mathematics, and science continue to play important roles in instructional improvement and accountability. State assessments must align to academic standards that are significantly more challenging than previous standards, reflecting the current knowledge and skill demands of postsecondary…

In March 2019 the Ministry of Education (MOE) commissioned NZCER to conduct an exploratory study of curriculum levelling in the Science and Mathematics and Statistics learning areas of "The New Zealand Curriculum" (NZC). The study was prompted in part by a desire to probe possible reasons for patterns of achievement reported by the…

The Washington State Board of Education (SBE) issues an annual report to the Governor, the Legislature, and the public, in accordance with the Charter School Act, RCW 28A.710.250. The statute requires the annual charter school report to include the following: (1) the performance of the state's charter schools during the preceding school year,…

This paper introduces the tactile method and aims to explore the effectiveness of using tactile methods with students who are blind and visually impaired. Although there was limited research about using this strategy, all of the research agrees that using tactile is one of the best ways for students who are blind and visually impaired to be…

The present research aimed to determine the relationship between Jordanian students' 21st century skills (Cs21) and academic achievement in science. The sample of the research consisted of a total of 96 eighth-grade students drawn from four rural and four urban schools in Irbid Qasaba in the governorate of Irbid. Randomly cluster sampling was used…

Numeracy activities in early childhood have been linked to children's mathematical performance in subsequent years. However, few studies have examined associations between early numeracy play and children's subsequent attitudes towards mathematics. This study draws on the Trends in International Mathematics and Science Study (TIMSS) 2011…

The purpose of current research is to explore the influence of a science teaching method course incorporating explicit reflective NOS instruction on pre-service science teachers' views of NOS and justifications in their arguments related to their decision-making on socio-scientific issues. This study is a case study and the participants were 5…

This study aims to investigate the applicability of context- and problem-based learning (C-PBL) into teaching thermodynamics and to examine its influence on the students' achievements in chemistry, retention of knowledge, students' attitudes, motivation and interest towards chemistry. The embedded mixed method design was utilized with a group of…

Since students have lost their interest in school science, several student-centered approaches, such as using topics that are relevant for students, inquiry-based learning, and discussion-based learning have been implemented to attract pupils into science. However, the effect of these approaches was usually measured in small-scale research, and…

General Chemistry is a high impact course at Benedictine University where a large enrollment of ~250 students each year, coupled with low pass rates of a particularly vulnerable student population from a retention point of view (i.e., first-year college students), make it a strategic course on which to focus innovative pedagogical development.…
