The Force Concept Inventory (FCI) is one of the research-based assessments established by the physics education research community to measure students' understanding of Newtonian mechanics. Former works have often recorded the notion of gendered mean FCI scores favoring male students notably in the North American (NA) based studies. Nevertheless,…

Previous research has suggested that changing the percentage of the course grade associated with exam grades in science, technology, engineering, and mathematics courses can change the gender gap in the course. It has also been shown that high-stakes assessments yield the lowest (relative) scores for female students. Previous research by the…

STEM education has experienced significant growth due to its pivotal role in innovation and economic development. While cognitive factors like prior knowledge are known predictors of STEM success, non-cognitive factors, including attitudes and demographics, also play vital roles. However, there is a notable scarcity of research focusing on the…

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…

In this study, we compare students' performance in solving mathematics and physics exercises with their confidence level in answering them. Accurate self-assessment of confidence is known to positively correlate with academic achievement, yet confidence is often neglected when designing teaching interventions. The research presented here aimed at…

Group differences in test scores are a key metric in education policy. Response time offers novel opportunities for understanding these differences, especially in low-stakes settings. Here, we describe how observed group differences in test accuracy can be attributed to group differences in latent response speed or group differences in latent…

The Fundamental Concepts for Organic Reaction Mechanisms Inventory (FC-ORMI) is a concept inventory with most items in a two-tier design in which an answer tier is followed by a reasoning tier. Statistical results provided strong evidence for the validity and reliability of the data obtained using the FC-ORMI. In this study, differential item…

According to the situated expectancy-value model, students' motivational beliefs interact and are influenced by situations. This study examined how within-person fluctuations in science-related self-concept, intrinsic value, and cost are associated over time among Helsinki elementary students (N = 538, ages 7-12). The random intercept cross-lagged…

Preparing students for science, technology, and engineering careers is an urgent state policy challenge. We examined the design and roll-out of a science testing requirement for high school graduation in Massachusetts. While science test performance improved over time for all demographic subgroups, we observed rising inequality in failure rates…

The study examined the effectiveness of concept mapping in improving students' academic performance using an embedded mixed-methods design. It involved Srinka Secondary School's grade 10 biology teacher, students, and department head in the study and gathered data from them by using biology achievement tests, interviews, and focus group…

We investigated two research questions: which students are more likely to respond inconsistently to mixed-worded questionnaire scales, and which country samples have larger shares of inconsistent respondents? We defined an inconsistent response as strongly agreeing or disagreeing with both positively and negatively worded items of the same scale.…

Gender disparity in science and mathematics performance is being researched internationally. In a complex education system, like Pakistan, studying the difference in isolation may not generate holistic understanding. Therefore, this paper investigates changes in trends of performance in Science and Mathematics for both genders across public and…

Concept inventories are widely used in physics education research, yet numerous studies show that concept inventories measure dramatically different learning gains in different demographic groups. Prior studies show that the performance gaps between demographic groups are already present in their preinstruction responses, suggesting that the…

Environmental sustainability and how best to promote sustainable development is a problem of increasing urgency for policymakers and researchers. Several international projects have been initiated to address these issues and provide frameworks for thinking about the development of individuals' environmental awareness and their proclivities for…

This study examined whether there was a significant difference between the End-of-Course Examination scores (EOC) across multiple academic disciplines between students who participated in sports and those who did not participate in athletics at all in three rural high schools in South Carolina. The theoretical foundation for this study was based…
