Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

Science teachers often use visual images to help students visualise the abstract concepts of science. Yet, they may not support students in making sense of these visual representations, wrongly assuming that the students can intuitively do it on their own. Pre- and in-service teacher professional development programmes also seldom explicitly teach…

This study aimed to foster students' critical thinking skills through the use of multiple representation-based worksheet. Through a quasi-experimental research design (non-equivalent control group design), the sample of the study consisted of 74 students drawn from a junior high school in North Lampung. This sample was divided into two groups to…

This paper examines the roles of multimodality and thematic patterns in the teaching of the particle model of matter. Although the particle model is a fundamental topic in science education, there is no consensus on (1) whether or not the model should be introduced in early grades and (2) how to introduce the model to students for the very first…

Describes the exploratory assessment of strategy for learning redox reactions in High School, which seeks to prevent students from developing memoristic and mechanical skills, in addition to emphasize the experiences of daily life that go unnoticed or unexplained to the student in the classroom and at the same time are able to incorporate the key…

Now visualization courses have been taught at universities around the world. Keeping students motivated and actively engaged in this course can be a challenging task. In this paper we introduce our developed interactive learning system called VisMis (Visualization and Multi-modal Interaction System) for postgraduate scientific visualization course…

With their sunny stripes and fuzzy bodies, bees are beloved--but unfortunately, they are in trouble. Bee decline, of both wild bees as well as managed bees like honey bees, has been in the news for the last several years. Habitat loss, diseases, pests, and pesticides have made it difficult for bees to survive in many parts of our world (Walsh…

In this paper, we present materials and teaching ideas utilizing multiple representations in the contexts of kinematics and the force concept. These ideas and materials are substantiated by evidence and can be readily used in teaching with no special training. In addition, we briefly discuss two multiple-choice tests based on physics education…

In this dissertation, I investigate the effects of a grounded learning experience on college students' mental models of physics systems. The grounded learning experience consisted of a priming stage and an instruction stage, and within each stage, one of two different types of visuo-haptic representation was applied: visuo-gestural simulation…

Framed in theories of social semiotics, this multiple case study describes and categorizes the actional-operational modes used by three middle school earth science teachers throughout the course of one school year. Data included fieldnotes, photographs, and video recordings of classroom instructions as well as periodic interviews with the…

The purpose of this study was to examine the changes in 19 preservice chemistry teachers' understandings of the structure of matter, including the aspects of the physical states of matter, the physical composition of matter, and the chemical composition of matter, before, immediately after, and months after they received a specific instruction.…

Teaching students to use and interpret representations in science is critically important if they are to become scientifically literate and learn how to communicate their understandings and learning in science. This study involved 248 students (119 boys and 129 girls) from 26 grade 6 teachers' classes in nine primary schools in Brisbane,…

Problem Statement: In recent years, researchers on learning have focused on learning with multimodal representation and this research has shown that when learners can interact with an appropriate representation their performance is enhanced. If students have the opportunity to interact consciously with modal representation, learning can be…

Writing-to-learn activities are designed to use writing as a process in which students generate and clarify understanding of scientific concepts for themselves, rather than simply communicating with a teacher for evaluation. Instead of having students parrot science facts back to the instructor, writing-to-learn activities focus on the production…
