Knowledge space theory (KST) is a mathematical framework for modeling and assessing student knowledge. While KST has successfully served as the foundation of several learning systems, recent advancements in machine learning provide an opportunity to improve on purely KST-based approaches to assessing student knowledge. As such, in this work we…

This study was designed to determine the effect of computer simulation instructional strategy on primary school pupils' achievement in basic science in Akure township in Ondo state, Nigeria. Constructivist theory was used as the framework, while the study adopted pretest-posttest control group quasi-experimental design. Four primary schools were…

Metacognitive ability is enormously important for improving students' learning performance. However, overconfidence bias may hinder students' metacognition abilities. Therefore, in this study, we conducted an intervention to reduce or debias overconfidence among students using the KAAR (knowledge, awareness, action, and reflection) model. Ninety…

Over the last decades, the percentage of the age group choosing to pursue university studies has increased significantly across the world. At the same time, there are university teachers who believe that the standards have fallen. There is little research on whether students nowadays demonstrate knowledge or abilities similar to that of the…

Studying nature from the atomic and molecular perspective gives students access to modern scientific paradigms and could improve achievement and motivation towards science learning. A visual and tactile approach to chemistry can form the foundation for a child-friendly but high-level chemistry curriculum and could be a powerful tool to invigorate…

The purpose of this study was to conduct a comparative analysis of pre-service primary school and science teachers' identification of scientific process skills. The study employed the survey method, and the sample included 95 pre-service science teachers and 95 pre-service primary school teachers from the Faculty of Education at Recep Tayyip…

Organic chemistry students struggle with multiple aspects of reaction mechanisms and the curved arrow notation used by organic chemists. Many faculty believe that an understanding of nucleophiles and electrophiles, among other concepts, is required before students can develop fluency with the electronpushing formalism (EPF). An expert concept map…

Photosynthesis is the most important biochemical process on Earth. Most living beings depend on it directly or indirectly. Knowledge about photosynthesis enables us to understand how the world functions as an ecosystem and how photosynthesis acts as a bridge between the non-living and living worlds. It is, therefore, understandable that…

This study investigated the interaction of disciplinary and interdisciplinary learning in a team-taught, first-year, interdisciplinary sustainability course. We surveyed (pre/post) both STEM (science, technology, engineering, and mathematics) and non-STEM majors (N = 241), assessing attitudes and content knowledge. Responses were analyzed using…

The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48-60 months) participated in the study. Semi-structured interviews were individually…

Research has shown that hands-on activities in biology/science education tend to improve children's attitudes towards science. These hands-on activities can influence children's interest in various ways, perhaps because they invoke varying emotions. We used a sample of 10-12-year-old children (n = 142) to examine the effect of hands-on activities…

Lecture capture technology is fairly new and has gained interest among higher institutions, faculty and students alike. Live-lecture (LL) is captured in real-time and this recording, LC, is made available for students to access for later use, whether it be for review purpose or to replace a missed class. Student performance was compared between…

Exemplary for social insects, "Temnothorax" ants allow for various hands-on investigations in biology classes. The aim of this study was to provide a quantitative and qualitative analysis of secondary school students' learning achievement after teaching units with ants lasting between one and six weeks. The questionnaires included…

This study investigated eighth-grade science students' (13-14-year-olds) perceptions of their vocabulary knowledge, learning, and content achievement. Data sources included pre- and posttest of students' perceptions of vocabulary knowledge, students' perceptions of vocabulary and reading strategies surveys, and a content achievement test.…

The paper describes a biology tutoring system with adaptive question selection. Questions were selected for presentation to the student based on their utilities, which were estimated from the chance that the student's competence would increase if the questions were asked. Competence was represented by the probability of mastery of a set of biology…
