The use of toys as teaching aids in physics classrooms has a rich history, and the role of play in science education is a well-established line of research. Much of what has been written on the topic has included discussions of specific toys and the implications of using those toys to teach physics. One of the toys from my childhood that seems to…

We demonstrated that an optimally designed pinhole camera can be used as an astronomical tool to observe the libration and apparent diameter change of the Moon at night. The libration and apparent diameter change of the Moon were observed using a handmade pinhole camera with a diameter of 0.65 mm and a focal length of 400 mm. It was found that the…

Teaching upper division statistical physics can often be clouded by the theory and complex examples used. To better help students appreciate the fundamental statistical concepts and how they are connected to thermodynamic principles this paper suggests using a simple abstract model. Using Atkins' Model students can see these ideas clearly…

Student motivation within a STEM course is dependent on their perceived relevance and utility of the topics learned. This paper presents an Informative Utility Value Intervention (IUVI) designed to promote perceptions of utility. The IUVI was designed as a series of assignments for general chemistry students in large lecture courses, but the…

Micropaleontology is a critical tool for determining the ages of geologic records, reconstructing ancient environments, and monitoring modern ecosystem health. However, most students are not exposed to micropaleontology in their college coursework. To enable non-expert instructors to integrate microfossil identification training in their…

Purpose: This study draws on Bruno Latour's work, "Down to Earth: Politics in the New Climatic Regime," to re-imagine issues of climate change in K-12 science teaching and learning. "Re-turning" to a dwelling place can become an investigation, while issues of gender, race, education, food, technology, and religion can be…

Students' success in physics problem-solving extends beyond conceptual knowledge of physics, relying significantly on their mathematics skills. Understanding the specific contributions of different mathematics skills to physics problem-solving can offer valuable insights for enhancing physics education. Yet such studies are rare, particularly at…

Orientation is a component of pedagogical content knowledge and represents a general view of teaching and learning science. Science instructors hold orientations to teaching science teachers and orientation can be illustrated by an instructor's purposes and goals for instruction. Due to the central role of the instructors in preparing qualified…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

This study provides insights into the use of metaphors in protein synthesis descriptions in upper secondary chemistry and biology textbooks. Data were collected from seven Swedish textbooks and analyzed with the Metaphor Identification Protocol and categorized within the framework of Conceptual Metaphor Theory. The results reveal two main parallel…

Cultivating in preservice science teachers (PSTs) the competence required to teach scientific models and modeling is a valued outcome of teacher preparation programs. However, science teacher educators face inherent tensions when designing and implementing teacher preparation experiences to achieve this outcome. In this systematic review, we first…

Rapid advancements in bioengineering call for broad public literacy to help individuals better understand the changes these technologies bring to our lives. However, making bioengineering concepts accessible and relevant, especially to non-science majors, is often challenging. To address this challenge, we designed a general education course aimed…

Climate change education is a challenge for teachers, as they must have appropriate content knowledge to teach the topic adequately. Every teacher is confronted with both their own knowledge and non-knowledge, as well as with scientific knowledge and non-knowledge. The uncertainty about this knowledge depends on individual perception and can have…

This article attempts to address the challenge that preschool teachers face, when integrating a specific content area, science, with play. The study builds on the theoretical framework of Play-Responsive Early Childhood Education and Care (PRECEC), in which teaching, and play are understood as a mutual activity. In this mutual activity, teachers…

Knowledge about genetics is essential to build a society capable of participating in socioscientific and ethical debates. However, this subject remains difficult for students, making it necessary to develop new educational strategies, such as gamification. Thus, two main objectives are established in this work: (a) to design and evaluate…
