This study investigated eight experienced science teachers' and eight senior high school students' metavisualization when they drew models to represent their concepts of carbon cycling. Qualitative data collection techniques including think-aloud tasks and follow-up retrospective interviews were employed. The purposes of the study included: (1) to…

Computational thinking (CT) is one of the systematic tools in problem solving and widely accepted as an important skill in the 21st century. This study aimed to identify the effectiveness of the Chemistry Computational Thinking (CT-CHEM) Module on achievement in chemistry. This study also employed a quasi-experimental design with the participation…

In three experiments, students were trained to use strategies for learning from scientific texts: text highlighting (Experiment 1), knowledge mapping (Experiment 2), and visualizing (Experiment 3). Each experiment compared a control condition, cognitive strategy training, and a combined cognitive strategy plus metacognitive self-regulation…

There were two purposes in the study. One was to explore the cognitive activities during spatial problem solving and the other to probe the relationship between spatial ability and science concept learning. Twenty university students participated in the study. The Purdue Visualization of Rotations Test (PVRT) was used to assess the spatial…

Learning to use visualisation techniques in the classroom enables pupils and teachers to gain new insights into how concepts are formed and how to strengthen them, but visualisation is sometimes not what it seems. Learning by constructing meaning is a long-standing principle underpinning much of today's school science. In "Primary Science…

Teachers' perception filter operates in all realms of their consciousness. It plays an important part in what and how students learn and should play a central role in what and how they teach. This may be obvious, but having a visual model of a perception filter can guide the way they think about education. In this article, the author talks about…

This article reports that as the need for students to be able to construct and critique scientific argumentation as emphasized in "A Framework for K-12 Science Education" (National Research Council 2012), teachers are wondering how to support students in this process. Scientific argumentation is defined as the interplay between…

The effects of dynamic and static visualizations in understanding physical principles of fish locomotion were investigated. Seventy-five students were assigned to one of three conditions: a text-only, a text with dynamic visualizations, or a text with static visualizations condition. During learning, subjects were asked to think aloud. Learning…

Two experiments are reported that investigated the relative effectiveness of a realistic dynamic visualization as opposed to a schematic visualization for learning about cell replication (mitosis). In Experiment 1, 37 university students watched either realistic or schematic visualizations. Students' subjective task demands ratings as well as…

This paper describes a three-year study conducted among chemistry instructors (professors and teaching assistants) at a post-secondary institution. The goal was to explore the integration process of information and communication technologies (ICT) into traditional teaching. Four undergraduate chemistry courses incorporated a course website, an…

Describes a procedure for teaching the "generator orbital" (GO) approach of molecular orbital bonding in polyatomic molecules. Explains how the GO can be utilized with students in generating the vibrational, rotational, and translational modes of molecules in a completely pictorial manner. (ML)

This instructional design looks at momentum in physics through railroading, to assist students in developing appropriate mental models that will enable them to solve problems relevant to the process or principle being taught. A PEAnet (process, entity, activity network) relationship enables an instructional visualization (simulation) in which…

Discusses a study which was designed to examine if spatial-visual skills are related to learning the volume concept and if a particular mode of presentation for teaching volume is preferable for students of differing spatial ability. Results indicate that students of low visual orientation benefit if volume is taught before area and length. (ML)
