The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

This paper describes a study in which five physical science teachers were requested to take photographs and describe the science concepts embedded in these. Particularly, the science had to be relevant to the grade 10-grade 12 curriculum they were teaching. This study was an exploratory case study employing qualitative methods. To analyze data…

This exploratory study investigated the relationships between time utilisation and the use of visual resources, supported by audiovisual records of the practices of pre-service chemistry teachers applying Teaching-Learning Sequences. The content analysis was based on analytical categories found in the scientific literature. The results showed a…

Novice chemists often struggle with the highly visual nature of some chemistry topics. To make visually demanding concepts, such as isomerism and stereochemistry, more accessible to students, chemistry instructors have long recommended the use of molecular model kits as visual aids. However, studies pertaining to student model usage have shown…

Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

The Interactive Whiteboard as a teaching tool, has been in use across schools and institutions in many countries. Bhutanese schools started using them for educational purposes in 2019. However, there is lack of evidence on their actual use and effectiveness in teaching physics to enhance students' learning. This study aimed to investigate the…

In biology learning, the object of a virus cannot be seen directly. Augmented reality (AR) technology can help visualize the object of a virus in 3D, making it easier for students to learn about viruses. Therefore, this research aims to develop an AR-based learning media product called ARVi. ARVi was created using the ADDIE model, which consists…

Many stakeholders emphasize the importance of diverse populations' participation in the sciences, though the motivations for this vary. Some reference an economic standpoint by emphasizing the importance of either recruiting more science workers to compete in a global economy, or of individual financial success for people from historically…

Most, if not all, physics undergraduate degree programs include instructional lab experiences. Physics lab instructors, both faculty and staff, are instrumental to student learning in instructional physics labs. However, the faculty-staff dichotomy belies the complex, varied, and multifaceted landscape of positions that lab instructors hold in the…

Background: New technology and increased collaboration have revolutionized how scientists work with data. This creates a need to identify new aspects of working with scientific data that are important for K-12 students to learn. Purpose: To address this need, we conducted a study with practicing scientists and K-12 science teachers. The purpose of…

Several studies have shown that "learner-generated external visual representations" (LGVRs) play a vital role for learning scientific concepts and processes. However, we know little about teachers' reasoning as to why and how to implement LGVR activities in their teaching. Thus, the purpose of our study is to determine why teachers let…

Although visual aids are widely considered a valuable source of scaffolding, the nature and active utilization of these aids in current science classrooms are not well understood. This qualitative study explores interaction in the teaching of concepts related to evolution, with a specific focus on a teacher's use of different visual support…

Understanding mechanisms underpinning formation of convection currents is pivotal for developing explanations of plate tectonics when teaching Geoscience topics. While student generated diagrams explaining convection currents may be used to evaluate student conceptual understanding and alternative conceptions in this topic, students may need…

Background: Spatial ability has an important place in science education, which is effective in raising future scientists. Although not in large numbers, studies show that teachers' spatial abilities somehow affect their teaching practices in the classroom and thus the spatial abilities of their students. Purpose: This study aimed to investigate…

Pedagogical content knowledge of science teachers includes knowledge of representational forms, such as visual displays. Past research has provided a general means to evaluate pictures, but is not fine-grained on features internal to pictures. Furthermore, many existing picture function typologies consider pictures as subservient to text, though…
