Demand for students with a solid foundation in science continues to grow. Also important, science education needs to ready citizens who do not pursue careers in science to handle dilemmas they will face in their lives, such as selecting treatments for diseases, evaluating messages about climate change, or using new technologies. Instruction that…

This article describes the power of goal-setting in order to help children become self-motivated and responsible for their actions. It also provides a road-map for a successful process by describing the following strategies: changing negative thoughts into positives, creating affirmations, designing action plans and utilizing visualization. This…

Present Educational Modelling Languages are used to formally specify abstract learning scenarios in a machine-interpretable format. Current tooling does not provide teachers/designers with some graphical facilities to help them in reusing existent scenarios. They need human-readable representations. This paper discusses the UML4LD experimental…

Spatial visualization is a fundamental skill in technical graphics and engineering designs. From conventional multiview drawing to modern solid modeling using computer-aided design, visualization skills have always been essential for representing three-dimensional objects and assemblies. Researchers have developed various types of tests to measure…

This article illustrates how to integrate mathematics with social issues. Social issues discussed in the newspaper provide a rich context for connecting mathematical activities to the real world. The sample activities focus on measurement concepts. (Contains 2 figures.)

Research investigating public speaking anxiety treatments is subject to demand effects. This study tests the relative effectiveness of systematic desensitization (SD) and multiple treatment method (MT) containing visualization therapy against no-treatment and credible placebo controls. Data (N = 238) were collected at six points in a public…

This study examined the effects of the Visual Thinking Strategies (VTS) curriculum on reading achievement of students with various motivational levels. A 2X2 factorial design was used. The sample population consisted of 104 fourth grade students from an upper middle class school system in Connecticut. All students were administered a…

LYDIAN is an environment to support the teaching and learning of distributed algorithms. It provides a collection of distributed algorithms as well as continuous animations. Users can combine algorithms and animations with arbitrary network structures defining the interconnection and behavior of the distributed algorithm. Further, it facilitates…

With both "Cabri" and "Autograph" now venturing into 3D, the dimension that previously was only demonstrated in the classroom with a lot of arm waving and crude wire cages can now be explored dynamically on screen. "Cabri 3D" concentrates on constructions, using the principles of Euclidian geometry, whereas "Autograph" creates objects using a…

Humans see whole objects from input fragmented in space and time, yet spatiotemporal object perception is poorly understood. The authors propose the theory of spatiotemporal relatability (STR), which describes the visual information and processes that allow visible fragments revealed at different times and places, due to motion and occlusion, to…

This study aims to investigate the effects of virtual reality (VR)-based learning environment on learners of different spatial visualization abilities. The findings of the aptitude-by-treatment interaction study have shown that learners benefit most from the Guided VR mode, irrespective of their spatial visualization abilities. This indicates that…

Memory for the position of a moving target is often displaced in the direction of anticipated motion, and this has been referred to as "representational momentum". Such displacement might aid spatial localization by bridging the gap between perception and action, and might reflect a second-order isomorphism between subjective consequences of…

This article uses the story of The Wonderful Wizard of Oz (L. F. Baum, 1900) as a metaphor for exploring career counseling issues related to self-deception, loss, and the search for the "all-knowing" expert. The dynamics of the story can be applied to both counseling practice and counselor training. Cross-cultural issues are also considered.

This investigation is part of a combined research/curriculum development project in which children's learning is being examined in the context of developing and testing instructional units on 3-D geometry in grades 3, 4, and 5. There are two components to the article. First, the strategies and cognitive constructions that students utilize to…

Synectics is an approach to creative thinking that depends on understanding together that which is apparently different. Its main tool is analogy or metaphor. The approach, which is often used by groups, can help students develop creative responses to problem solving, to retain new information, to assist in generating writing, and to explore…
