Students often find the difference in the electromagnetic and the acoustic Doppler formulae somewhat puzzling. As is shown below, geometrical diagrams and the concept of "event"--a point in spacetime having coordinates (x,y,z,t)--can be a useful and simple way to explain the physical background behind the fundamental differences between the two…

Asking students to manipulate digital photos on the computer is one of the easiest ways the author knows to engage their attention. It's fabulous fun for them and a great teaching tool for educators. In this article, the author presents 10 ways to impress students with image-editing software. These are: (1) filters are fascinating; (2) get a move…

Semiotic work is principled engagement in the making of meaning. The semiotic work of school-based learning entails interpretation and expression framed by the curriculum and the social practices of the classroom, and realized multimodally in diverse pedagogic interactions and activities. Micro-examination of the relationship between a teacher's…

In this paper, we devise a diagrammatic conceptualization to describe and represent the complex interplay of a teacher's knowledge (K), goals (G) and beliefs (B) in leveraging technology effectively in the classroom. The degree of coherency between the KGB region and the affordances of the technology serves as an indicator of the teachers'…

To acknowledge both conceptual and situational factors, children's understanding of the Earth was considered from three angles: 1. the perspective as the physical point or direction from which something is seen or depicted; 2. conceptual frameworks; 3. the relevance of explanations in a situation. Fourteen children were interviewed individually in…

This study examined children's tendency to confuse events that varied in source similarity, which was manipulated using different media of event presentation. In Experiment 1, children in two age groups (3- and 4-year-olds and 5- and 6-year-olds) experienced a live presentation of an event, and another event was either heard from a story (low…

Get an in-depth understanding of how to create fun, engaging, and challenging performance assessments that require students to elaborate on content and demonstrate mastery of skills. This update of an ASCD (Association for Supervision and Curriculum Development) classic includes new scoring methods, reading assessments, and insights on navigating…

"Science Learning and Instruction" describes advances in understanding the nature of science learning and their implications for the design of science instruction. The authors show how design patterns, design principles, and professional development opportunities coalesce to create and sustain effective instruction in each primary scientific…

When a child has disabilities, families and professionals must communicate their concerns and goals for the child. Often these concerns are expressed as weaknesses within a deficits-based framework. The use of a strengths-based, family-created portfolio is a communication strategy for reconceptualizing a child from the family's perspective in…

Many animals are currently facing extinction. Conservation education which highlights the impacts of our behaviour on other species survival is crucial. This study provides evidence for the use of visual media to increase knowledge, attitudes and conservation behaviours regarding the highly endangered orangutan. University students (n = 126) were…

Advances in neuroscience have brought new insights to the development of cognitive functions. These data are of considerable interest to educators concerned with how students learn. This review documents some of the recent findings in neuroscience, which is richer in describing cognitive functions than affective aspects of learning. A brief…

The purpose of the study was to investigate the elementary school students' perception towards the traditional over smart classroom instruction. In the present study, one hundred elementary school students from two Indian schools have been randomly selected as the sample of the study. The learners' perception scores were analyzed by chi-square and…

The objective of this quasi-experimental quantitative study was to determine if the use of a student response system, combined with an interactive whiteboard, led to increased student achievement in mathematics within a fifth grade classroom as measured by a district benchmark assessment and the annual Arizona Instrument to Measure Standards…

It is intuitively felt that visual cues should enhance online communication, and this experimental study aims to test this prediction by exploring the value provided by a webcam in an online L2 pedagogical teacher-to-learner interaction. A total of 40 French undergraduate students with a B2 level in English were asked to describe in English four…

In this paper, the authors summarize a quantitative analysis demonstrating that the CyGaMEs toolset for embedded assessment of learning within instructional games measures growth in conceptual knowledge by quantifying player behavior. CyGaMEs stands for Cyberlearning through GaME-based, Metaphor Enhanced Learning Objects. Some scientists of…
