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…

In this study, we applied elastic-net logistic regression to explore critical predictors of students' mathematics and science levels using data from eighth-grade students in the 2019 Trends in International Mathematics and Science Study (TIMSS). The elastic-net approach, a machine learning based approach combining Ridge and Least Absolute…

Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences. Past research has…

This study seeks to determine whether giving an explicit incentive to students in an upper-division first-semester electromagnetism course (EM1), in the form of partial credit for reworking unit exam problems, will improve their problem-solving skills as measured by performance on identical problems on the final exam. Three problems--a primarily…

Visualizing effects of images on improved anatomical knowledge are evident in medical and allied health students, but this phenomenon has rarely been assessed in nursing students. To assess the visualizing effect of images on improving anatomical knowledge and to use images as one of the methods of gross anatomical knowledge assessment in nursing…

Explicit-reflective nature of science (NOS) instruction has demonstrated a positive impact on student learning. Although explicit-reflective NOS instruction often consists of questions that draw students' attention to NOS ideas, there are few recommendations in the science education literature about how the form of these questions might inform NOS…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

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…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students' conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring…

During a two-year span, a cohort of K-8 science teachers undertook the task of creating formative assessments aligned with the Next-Generation Science Standards for their individual classrooms. Practice-based professional development was utilized to support teachers in a cyclical manner as they cooperatively developed, administered, and reflected…

Students with strong metacognitive skills are positioned to learn and achieve more than peers who are still developing their metacognition. Yet, many students come to college without well-developed metacognitive skills. As part of a longitudinal study on metacognitive development, we asked when, why, and how first-year life science majors use…

Many undergraduate chemistry students hold alternate conceptions related to resonance--an important and fundamental topic of organic chemistry. To help address these alternate conceptions, an organic chemistry instructor could administer the resonance concept inventory (RCI), which is a multiple-choice assessment that was designed to identify…

International large-scale assessments (ILSA) are an important source of information for education policymakers across the globe. Despite sponsors' warnings, when results are published, media attention focuses on country rankings and changes in scores. Score changes are evaluated using a two-sided z-statistic, with statistical significance declared…

Students and educators often face time constraints, making it essential to develop interventions that are both easy to implement and have a substantial impact on learning and performance. One promising strategy is retrieval practice, particularly in the context of physics education, where many students struggle with basic knowledge. Prior research…
