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…

The educational benefit of the traditional didactic lecture to learners in Higher Education is hotly debated. Given increasing student numbers, existing technical set ups and many logistical concerns, lectures remain the norm in many Higher Education Institutions (HEIs). In this personal view piece, we discuss the benefits, opportunities, and…

It is of great importance to examine the level of science teaching self-efficacy (SE), which is related to technological developments in primary school teacher education. It is seen that this subject is not addressed in the context of technological pedagogical content knowledge (TPCK) and visual metaphors. The purpose of this research was to…

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 use of group drawing to promote student-generated representation is a common instructional strategy as it combines the benefits of using visual representation and collaborative talk. Although the affordances of group drawing have increasingly been emphasized in science education, few studies have investigated how drawing as a visual mode…

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…

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…

Representation in science is anything that stands for something else--drawings, pictures, graphs, or other representational forms (Danish et al. 2020). Representations serve as public displays of phenomena that make aspects of those phenomena explicit (Gilbert 2008). They can serve to make the invisible visible, communicate ideas, display…

Understanding genetics is one of the most significant learning difficulties faced by students. To improve teaching genetics and the students' representational competence within the classroom have been proposed using multiple representations. This study presents an analysis of representational levels used by high school students learning Mendelian…

There has been a recent increase in research interest in the ways that visual representation is used to facilitate students' understanding in science classrooms. Yet while many studies have explored individual students' drawing, few studies have looked into drawing as a collective tool to engage students in thinking and talking together in science…

Here, we describe the development and validation of an automatic assessment system that examines students' hand-drawn visual representations in free-response items. The data were collected from 1,028 students in the second through 11th grades in South Korea using two items from the Test About Particles in a Gas questionnaire (Novick &…

Background: Although the reading of science texts has been reported for high school learners, there is not much research on how younger learners engage with expository texts and how they develop academic language skills. In the instance of this study, the topic came from the curriculum content about animal reproduction. Aim: The study from which…

This paper describes a pictorial approach to Lenz's law that involves following four steps and drawing three pictures to determine the direction of the current induced by a changing magnetic flux. Lenz's law accompanies Faraday's law, stating that, for a closed conducting loop, the induced emf (electromotive force) created by a changing magnetic…
