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…

This study focused on the relationships between teacher characteristics and students' mathematics achievement in EU countries, including Hungary, Italy, Lithuania, Malta, Slovenia, Sweden, and Turkey, which are the only EU countries participated in TIMSS 2015 at the eighth-grade level. The data consisted of the sample of 31,969 eighth-grade…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

The study aims to investigate how confidence in mathematics/science, amount of books in the home, gender, whether a student likes being in school, and computer software predicted mathematics and science achievements of students in the Trends in International Mathematics and Science Study (TIMSS) 2019. The sample of the study consisted of…

Assessment of learners in the anatomical sciences is a complex task as it not only tests students' fact knowledge, but also the analysis of visual information. Sometimes, novice histology learners must acquire image recognition skills of microscopic structures in a short time frame. This paper describes a strategy of offering first year dental…

Students often report using ineffective study techniques. This project encouraged practice testing, distributed practice, interleaved practice, and metacognitive accuracy to increase learning in an undergraduate general chemistry course. Overall, the purpose of this project was to use text messaging to support evidence-based study practices.…

This study investigated student and classroom level variables related to student science achievement by using the Trends in International Mathematics and Science Study (TIMSS) 2015 dataset. Multilevel modeling was applied in this secondary analysis to examine how science self-concept, school relatedness, and science teaching quality predicted…

The aim of the study is to reveal the concurrent validity of the Central Examination of Secondary Education Institutions (OKMS). For this purpose, the relationship between the OKMS subtest raw scores of the students who took the exam and the 8th-grade year-end achievement scores of the courses within the scope of the exam was analyzed by canonical…

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…

Online quizzes and learning platforms provided by textbook publishers have become common components of undergraduate education. Here, I examine how participation in these formative assessments related to student course performance. Over multiple semesters, students completed either free online unlimited attempt quizzes or assignments from a…

The aim of this study was to examine which topic- and learning-related knowledge and motivational beliefs predict the use of specific deep-level learning strategies during an independent learning task. Participants included 335 Estonian fourth- and sixth-grade students who were asked to read about light processes and seasonal changes. The study…

In this study, we investigated female and male students' sense of belonging and their academic performance measured by the Force Concept Inventory (FCI) and course grades in a calculus-based introductory physics course at a large public university in the United States. We find that compared to male students, female students' sense of belonging was…

The present study was conducted to explore the differential levels of scientific aptitude among the economically disadvantaged students of Jammu and Kashmir. The objectives of the study were to find out of the achievement in the subject science of economically disadvantaged secondary school students and the levels of scientific aptitude of…

This paper examines whether scientific reasoning skills predict people's susceptibility to epistemically suspect beliefs and cognitive biases. We used the recently developed Scientific Reasoning Scale (SRS) because it measures the ability to read and evaluate scientific evidence. Alongside the SRS, 317 participants aged 18-30 years completed…

As scientific literacy plays a contributing role in identifying, analysing, and solving environmental matters that our world is facing, there is growing consensus to mandate environmental matters in science classrooms following five decades of efforts in promoting environmental education. However, much remains unknown about the relationship…
