Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…

This study aims to investigate the relationship between some protective factors and the academic achievements in science and mathematics classes of socioeconomically disadvantaged eighth-grade students. The quantitative research method and relational screening model were employed in the research. The sample of the study consisted of 250 students…

Biology education is crucial for living in a volatile, uncertain, complex, ambiguous, disruptive, and diverse environment. Moreover, most literature suggested developing learning activities for students based on the knowledge, attitudes, and skills competency gaps. Thus, this study assessed the academic performance in terms of their examination…

In this study, in line with TIMSS 2019 data, 8th grade students' school engagement in the Turkish education system and various variables in the field of science and mathematics, which are thought to be related to school engagement, were examined with the Random Forest method, a method amongst data mining methods. This research focuses on student…

Student' achievement in science can be affected by teacher subject matter knowledge, ineffective instructional methods, and lack of student engagement. Although all schools provide professional development opportunities, not all teachers choose to engage in a program that provides teaching and learning through experiential techniques for the…

At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school-aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest…

THS is applied to Science High Schools, Social Sciences High Schools, Anatolian Technical Programs of Vocational and Technical Anatolian High Schools and Project schools for student selection. With THS, approximately 10 percent of more than one million students are placed in a secondary education institution based on their preferences. The purpose…

The Japanese lesson study (JLS) model for curriculum development has seen limited application to middle school science classrooms. The JLS model was used to develop and refine three hands-on activities focused on four major eighth grade science topics from the California curriculum. Prior assessments of these topics showed limited understanding by…

Results from the Trends in International Mathematics and Science Study (TIMSS) assessments have shown that students in Korea displayed high levels of science achievement. In order to understand those achievement outcomes, a number of studies have examined science teaching in Korea and explored the effects of teaching practices on student…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

The purpose of this study was to examine eighth-grade students' science performance in terms of two test design components, item format, and cognitive domain. The portion of Taiwanese data came from the 2011 administration of the Trends in International Mathematics and Science Study (TIMSS), one of the major international large-scale assessments…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

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…

Using Malaysia TIMSS 2015 data, this study examined the association between eighth grade students' science achievement and mathematics score and the determining factors of science achievement. A total of 9,726 students participated in TIMSS 2015 with an average score of 508.60 with standard deviation of 89.86 for science and 501.57 with standard…
