Advancements in handheld computing, particularly its portability, social interactivity, context sensitivity, connectivity, and individuality, open new opportunities for immersive learning environments. This article articulates the pedagogical potential of augmented reality simulations in environmental engineering education by immersing students in…

In the final paragraph of his 1984 book "From knowledge to wisdom, a revolution in the aims and methods of science," the philosopher Nicholas Maxwell boldly declared that an intellectual revolution was underway in the aims and methods of science, and academic inquiry in general, from what he termed knowledge-inquiry to wisdom-inquiry.…

A comparative study was conducted to compare two approaches to engineering design curriculum between different schools (inter-school) and between two curricular approaches, "Project Lead the Way" (PLTW) and "Engineering Projects in Community Service" (EPIC High) (inter-curricular). The researchers collected curriculum…

The use of hybridity today suggests a less coherent, unified and directed process than that found in the Enlightenment science's cultural imperialism, but regardless of this neither concept exists outside power and inequality. Hence, hybridity raises the question of the terms of the mixture and the conditions of mixing. Cultural hybridity produced…

The objective of this study was to evaluate grade 9-12 students' motivation while engaged in two different engineering design projects: marble-sorter and bridge designs. The motivation components measured in this study were focused on students' intrinsic (IGO) and extrinsic (EGO) goal orientations, task value (TV), self-efficacy for learning and…

This paper presents concepts and principles pertinent to the development of cross-level and multilevel theory in organizational science by addressing a number of fundamental theoretical issues. It describes hierarchy theory, systems theory, and mixed-level models of organization developed by organizational scientists. Hierarchy theory derives from…

What follows is a description of a simple experiment developed in a non-mathematical general education science course on sound and light for fine arts students in which a guitar is used with data collection hardware and software to verify the properties of standing waves on a string.

Summarizes the historical development of lasers, involving basic concepts in physics, applied technology, advanced experimental techniques, and human interactions. Indicates that the potential for invention of the laser had been with us at least 30 years before the event actually occurred. (CC)

Discusses a model for the collinear collision of an atom with a diatomic molecule on a simple potential surface. Indicates that the model can provide a framework for thinking about molecular collisions and reveal many factors which affect the dynamics of reactive and inelastic collisions. (CC)

Deals generally with historical errors in science teaching and specifically with Newton's conception of his second law of motion. With reference to Newton's "Principia", the author concludes that Newton would not understand what we today refer to as "Newton's Second Law." (MLH)

This document presents a discussion of the postulated mechanism that leads to the materialization and dematerialization of matter and to antigravity. The mechanism also explains why an orbital electron does not radiate energy, in contradiction to classical electromagnetic theory. One of the paradoxes of special relativity is explained. A new model…

This study initiated in 1950, tested two hypotheses: (1) that as elementary school children progress through school their concepts of terms and principles in science become more correct, and (2) that elementary school children in 1964 would be more correct in their concepts of scientific terms and principles than similar children were in 1950. An…

A level of organization schema is presented which uses the concept of the organism as the pivotal unit and emphasizes biological relationships. (BB)

Describes a science activity which allows secondary level students to discover the law of refraction. (SL)
