Big Ideas in school mathematics can be seen as overarching concepts that occur in various mathematical topics in a syllabus. For teachers, this knowledge can be used to help students develop a better understanding of mathematics by making visible the central ideas, and connection across topics and across levels. For students, this knowledge can…

A word association test was used to determine knowledge structures on biochemistry concepts of secondary school chemistry students, aged between 18-19 years. The basic biochemistry concepts related to the topic of Carbohydrates that take place in the International Baccalaureate Diploma Programme curriculum were determined as stimulus words:…

Research has revealed that a small percentage of weekly instructional time in the elementary grades is dedicated to teaching science. Additionally, elementary educators receive limited preparation to teach science concepts compared to math or literacy skills. Therefore, this study examined if utilizing poetry to teach science concepts had a…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

The purpose of this study was to quantitatively assess the integration of computational thinking with learning about biological evolution. Specifically, we investigated the effectiveness of a framework from a recently developed learning progression that emphasises the complex nature of teaching both computational thinking and biological evolution.…

Although citizenship's literacy in biodiversity is a promising way of confronting its loss, the unawareness about this topic is generalised particularly regarding plants. The latter phenomenon, named Plant Blindness (PB), not only refers to the inability to notice and identify the surrounding plants, but also to the lack of knowledge about the…

The authors describe an instructional model of interdisciplinarity that aims to simultaneously develop undergraduate students' disciplinary knowledge and foster integrative skills. Two faculty members taught separate undergraduate courses in history and microbiology during which students came together at multiple points throughout the semester.…

Analogies are useful tools for teaching difficult scientific concepts and clearing up learners' misconceptions. However, if not properly used, they can lead to further misconceptions. More importantly, little is known about how science teachers use analogies in Nigerian classrooms. This study assessed science teachers' use of analogies by…

Disasters continue to have adverse effects around the globe leaving many lives susceptible to hazards and fatalities most especially children. The Philippines, known to be one of the most disaster-prone countries in the world, experiences earthquakes, typhoons, and flooding yearly. For the reason of the country's vulnerability to disasters, it is…

In this exercise, participants create a fictional business based on a set of randomly generated words. This challenge requires participants to exercise creativity, while reinforcing the business concepts learned in class. The exercise has four steps: (1) generating a prompt of three random words, (2) designing a fictional business based on this…

Despite years of research and practice inspired by chemistry education research, a recent report shows that US secondary instruction is not aligned with current national reform-based efforts. One means to mitigate this discrepancy is focusing on pedagogical conceptual change, its precursors (higher selfefficacy and pedagogical discontentment), and…

The Physiology Core Concept of flow down gradients is a major concept in physiology, as pressure gradients are the key driving force for the bulk flow of fluids in biology. However, students struggle to understand that this principle is foundational to the mechanisms governing bulk flow across diverse physiological systems (e.g., blood flow,…

Visual literacy, which is the ability to effectively identify, interpret, evaluate, use, and create images and visual media, is an important aspect of science literacy. As molecular processes are not directly observable, researchers and educators rely on visual representations (e.g., drawings) to communicate ideas in biology. How learners…

The way in which informal learning in a Personal Learning Environment (PLE) is coordinated is poorly understood. Conversation -- with teachers, friends or family -- contributes to the processes involved in meaningfully negotiating resources. While institution-centric education creates contexts for conversations and codifies educational attainment,…

Drawing, constructing, and explaining a model of a given abstract phenomenon is a challenging task. In this study, students were engaged in the "Project-Based Inquiry Science (PBIS)-Air Quality" learning unit, as part of their chemistry curriculum. The study aim is to determine how well students understand chemistry conceptually after…
