Stereotypical imagery of scientists is detrimental to effective and inclusive science education. Many elementary pre-services teachers often hold onto these images, creating an unconscious bias limiting their effectiveness to both teach science content and discourage some groups from entering the scientific field. Proactive and targeted…

This study aims to explore the meanings communicated by young children with visual cultural semiotic resources available in the science classroom. It is a case study in an Early Childhood Education classroom of 23 children (3-4 years old) and their teacher, all engaged in a long-term science project about snails. We focus on the analysis of two…

Visual representations in molecular biology tend to follow a set of shared conventions for using certain shapes and symbols to convey information about the size and structure of nucleotides, genes, and chromosomes. Understanding how and why biologists use these conventions to represent DNA is a key part of visual literacy in molecular biology.…

Drawing is a powerful process tool that supports learning in life science classrooms. Effective drawing activities frame drawing as a learning process and explicitly incorporate observation and communication. The goals of this article are to situate drawing as a valuable learning experience and to guide educators through designing and implementing…

Representations in chemistry are the tools by which students, instructors, and chemists reason with chemical concepts that are abstract. Although representations are regularly used within the chemistry classroom, there is more to uncover regarding the ways students interact with representations when given chemistry tasks. This study aimed to…

Biology and art have been linked throughout history. Early scientists, such as Leonardo de Vinci and John James Audubon, used sketches and painting to document their findings. Even early hominids left evidence of their world through cave art. Histology, the microscopic study of tissues and cells, relies on defining shape and spatial relationships…

Insects form a highly diverse taxonomic group, which has fundamental ecological functions, but is currently in a process of mass extinction. Here, we present the first cycle of design, implementation, and assessment of a didactic sequence oriented towards improving pre-service teachers' knowledge and appreciation of insect diversity. A…

The paper reports how a teacher and her students use drawings as a resource for observations and how such observations are connected to different epistemic practices in science lessons. Interactional data in a 1st grade classroom were analyzed based on Ethnography in Education. Results show that the use of drawings materialized children's…

Students need a strong understanding of how to represent chemical compounds in order to succeed in organic chemistry. This project set out to gain a better understanding of students' difficulties with symbolic representations, by identifying the specific errors associated with drawing wedge-dash structures. The focus was on how students…

In recent years, studies by education researchers indicate that, despite various instructional methods to enhance the conceptual understanding of seasons, the reasons for the formation of seasons and the processes involved are still not fully grasped. This research aims to investigate the fundamental reasons for the difficulties in comprehending…

The construction of a concept can be developed from the students' prior knowledge. Regarding deaf students, it is considered their conceptions conceived through vision. Given this, the present research was conducted with a group of deaf students in the 7th year of elementary school with the aim of verifying what ideas these students had about…

Effective teaching requires the use of techniques and strategies to counter student passivity and enhance engagement. Research demonstrates that drawing improves memory retention, increases motivation to learn, provides an opportunity to learn what makes an image an effective communication tool, allows demonstration of conceptual understanding,…

Recent research suggests that integrating model-based learning and socioscientific issue based instruction helps students construct meaningful learning in science classrooms. Thus, this paper presents a unit plan that integrates model-based learning and socioscientific issues. The focus of the unit is the white butterfly which is a local pest. A…

The purpose of this article is to describe a modeling sequence about the digestive system. "What happens in your body when you have lactose intolerance?" is the initial question that will guide the activities. Students will build a 3D plaster cast of the digestive system as part of a modeling cycle through which they are expected to…

Perhaps the most commonly cited student idea about forces in the literature is the notion of an impetus force, defined as the "belief that there is a force inside a moving object that keeps it going and causes it to have some speed," that can then "fade away as the object moves along." According to the literature, even after…
