Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

The aim of this study was to identify students' motivational beliefs in science and revealed the connections between the profiles and three cognitive dimensions of science achievement through the examination of the socio-economic status (SES) and gender covariates of the profile memberships. Latent profile analysis using science motivational…

The jigsaw model is a dynamic cooperative learning approach where students become experts on different segments of the material and teach their peers, thereby enhancing engagement accountability, team work, and ultimately improving academic achievement. This study investigated the effectiveness of a cooperative learning strategy on secondary…

This study investigates the impact of constructivist teaching methods on achievement and misconceptions in mechanics, with a focus on gender differences. The research involved 88 first-year physics students enrolled in the physics teacher training program. Using a quasi-experimental design, students were divided into experimental (constructivist…

Noticing the inconsistency in previous studies of gender differences in learning physics, it was determined to check whether a gender gap exists in a relatively large sample of competitors (N = 12,966) from Serbia. The aim of the research presented here was to analyze the achievements of male and female lower secondary school students, competitors…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

Metacognition and curiosity play an important role in the educational process. Therefore, it is significant to examine their correlation with students' performance and satisfaction with classes. In order to examine whether the effect of metacognition and curiosity on physics performance and satisfaction with physics classes depends on gender, a…

Globally, the private school share of enrollment increased from about 14 percent in 2000 to about 18 percent in 2019. We estimate the systemic effect of private enrollment share on learning outcomes. Estimates of the systemic effect of private school enrollment capture any competitive effects as well as any differences between public and private…

This study aims to investigate the impact of using the flipped classroom strategy on motivation and academic achievement in learning science among 9th-grade students Proved as an innovative technique, flipped learning improves academic performance, enhances students' motivation, supports independent learning, triggers higher thinking skills, and…

Gender diversity signals inclusivity, but meta-analyses suggest that it does not boost individual or group performance. This research examined whether a social-psychological intervention can unlock the benefits of gender diversity on college physics students' social and academic outcomes. Analyses of 124 introductory physics classrooms at a large…

Students' view of intelligence (i.e., their mindset beliefs) has been found to be related to their self-efficacy and goal orientations as well as to influence their course outcomes. Comparisons of students' chemistry mindset between different groups found that organic chemistry I students held more of a growth mindset than general chemistry I…

In this study, we investigated how gender and implicit theories of mathematics and science abilities interacted to predict mathematics and science achievements in a sample of elementary (primary) school students from the United States. Study participants came from six elementary schools (Grades 2 to 5) and were a part of a larger sample that…

Background: Science educators around the world have recognised that difference in performance exists between male and female students in chemistry and there have been several efforts and interventions through research and workshops to bridge this gap. Purpose: Owing to the current growth of the effects of the use of computer simulations on…

The end of college is a key transition point when students prepare for the workforce or graduate school, and when competence beliefs that have been shaped throughout college play a particularly important role in decision-making processes. This study examined the roles of two competence beliefs, self-efficacy for scientific tasks and science…

The aim of this study is to determine the academic achievements of 8th graders in mathematics and science courses and STEM skill levels. The research has been carried out with the survey model. The sample of the study consists of 251 8th grade students in the 2020-2021 academic year. Math and Science academic achievement tests and STEM skill…
