In this study, we sought to examine the influence of a 12-week design-based elective Science, Technology, Engineering, and Mathematics (STEM) course on pre-service chemistry teachers' content knowledge, STEM conceptions, and engineering and engineering design views. To attain the goals determined, we utilized five STEM activities starting with a…

The increased emphasis on STEM related careers and the use of science in everyday life makes learning science content and concepts critical for all students especially for those with disabilities. As suggested by the National Resource Council (2012), more emphasis is being placed on being able to critically think about science concepts in and…

Disciplines such as Biochemistry and Molecular Biology, which involve concepts not included in the high-school curriculum, are very challenging for many first year university students. These subjects are particularly difficult for students accustomed to surface learning strategies involving memorization and recall of facts, as a deeper…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study designed to measure trends in mathematics and science achievement at the fourth and eighth grades, as well as to collect information about educational contexts (such as students' schools, teachers, and homes) that may be related to student…

The National Assessment of Educational Progress (NAEP) is the largest nationally representative and continuing assessment of what the nation's students know and can do in various subjects such as mathematics, reading, science, and writing, as well as civics, geography, technology and engineering literacy, and U.S. history. The results of NAEP are…

This document describes the features of a statewide summative science assessment that has been designed to embody standards based on the "Framework for K-12 Science Education," such as the Next Generation Science Standards (NGSS)--to reflect its intent, grounded in the specific expectations of three-dimensional standards. Importantly,…

This article addresses the issue of language-related construct-irrelevant variance on content area tests from the perspective of systemic functional linguistics. We propose that the construct relevance of language used in content area assessments, and consequent claims of construct-irrelevant variance and bias, should be determined according to…

The purpose of this study was to apply two types of Differential Item Functioning (DIF), net and global DIF, as well as the framework of Differential Step Functioning (DSF) to real testing data to investigate measurement invariance related to test language. Data from the Program for International Student Assessment (PISA)-2006 polytomously scored…

Scientific reasoning competencies are relevant science competencies and therefore the development of assessment instruments for scientific reasoning competencies has become an integral part of science education research. However, some authors have questioned the validity of the instruments available so far, since their psychometric quality has not…

School climate which is strongly related with the students' outcomes includes some of the components, among which disciplinary climate in schools was expressed as the dominant one. Safety and order in schools which is strongly related with the physical and emotional security stated as one of the indicator of disciplinary climate in schools. In…

For scholars and policy-makers alike, deeper learning has been a promising paradigm for fostering students' interest in and mastery of science, technology, engineering, and mathematics (STEM). Deeper learning is assumed to result in a more thorough understanding of a subject that endures the test of time. To reach this level, a fascination with…

The chapters in this online volume comprise the TIMSS & PIRLS International Study Center's technical report of the methods and procedures used to develop, implement, and report the results of TIMSS 2019. There were various technical challenges because TIMSS 2019 was the initial phase of the transition to eTIMSS, with approximately half the…

The Spring 2020 Nebraska Student-Centered Assessment System (NSCAS) General Summative testing was cancelled due to COVID-19. This technical report documents the processes and procedures that had been implemented to support the Spring 2020 assessments prior to the cancellation. The following sections are presented in this technical report: (1)…

This is the 21st report by the National Center on Educational Outcomes (NCEO) that describes how states publicly report assessment data for students with disabilities in K-12 schools in the United States. The purpose of this report is to examine the extent to which states reported 2017-18 assessment data for students with disabilities "to the…
