Advances in computer and interface technologies have made it possible to create three-dimensional (3D) computerized models of anatomical structures for visualization, manipulation, and interaction in a virtual 3D environment. In the past few decades, a multitude of digital models have been developed to facilitate complex spatial learning of the…

When natural language input contains grammatical forms that are used probabilistically and inconsistently, learners will sometimes reproduce the inconsistencies; but sometimes they will instead regularize the use of these forms, introducing consistency in the language that was not present in the input. In this paper we ask what produces such…

Chemists have used computational science methodologies for a number of decades and their utility continues to be unabated. For this reason we developed an advanced lab in computational chemistry in which students gain understanding of general strengths and weaknesses of computation-based chemistry by working through a specific research problem.…

From media news coverage to fluctuating gas prices, the topic of energy is hard to ignore. However, little connection often exists between energy use in our daily lives and the presentation of energy-related concepts in the science classroom. The concepts of energy production and consumption bring together knowledge from several science…

The modality-match effect in recognition refers to superior memory for words presented in the same modality at study and test. Prior research on this effect is ambiguous and inconsistent. The present study demonstrates that the modality-match effect is found when modality is rendered salient at either encoding or retrieval. Specifically, in…

This article responds to "Laboratory experiments as a tool in the empirical economic analysis of high-expectation start-ups" by Martin Curley and Piero Formica, published in the December 2008 issue of "Industry and Higher Education." The exploitation of knowledge and experience is increasingly important to companies operating in the globalized…

Prior research demonstrated that writing synopsis laboratory reports (succinct syntheses of the experiment, lecture, and readings) instead of traditional laboratory reports, did not influence student learning as measured by comprehensive exam scores. This study extended this research by investigating the impact of these lab report formats on…

Dilated canine hearts were used to teach undergraduate students internal and external cardiac anatomy. The specimens were dilated using hydrostatic pressure and then fixed using 5% formalin. These specimens provided the students with an alternative to prepackaged embalmed hearts and anatomical models for studying the external and internal cardiac…

The following experiment describes an easy experiment for children 11-12 years old, performed during spring in a compulsory school near Karlstad, Sweden. Four different ripe fruits were placed under flowering plants of Impatiens New Guinea (Impatiens hawkeri) for four days on a table and with plastic bags around both plants and fruits. For one of…

This paper describes the implementation of an open-ended inquiry experiment for high-school students, based on gas chromatography (GC). The research focuses on identifying the level of questions that students ask during the GC open inquiry laboratory, and it examines whether implementing the advanced inquiry laboratory opens up new directions for…

For teachers, a common difficulty when introducing scientific thinking is finding ways to engage the participation of the students. Because most scientific problems require at least some specialized knowledge to formulate and solve, it can be hard to go beyond merely discussing the steps of the scientific method and illustrating them with the…

Two experiments investigated whether motion metaphors for time affected the perception of spatial motion. Participants read sentences either about literal motion through space or metaphorical motion through time written from either the ego-moving or object-moving perspective. Each sentence was followed by a cartoon clip. Smiley-moving clips showed…

This study examines the working memory systems involved in human wayfinding. In the learning phase, 24 participants learned two routes in a novel photorealistic virtual environment displayed on a 220 degrees screen while they were disrupted by a visual, a spatial, a verbal, or--in a control group--no secondary task. In the following wayfinding…

Molecular biology techniques play a very important role in understanding the biological activity. Students who major in biology should know not only how to perform experiments, but also the reasons for performing them. Having the concept of conducting research by integrating various techniques is especially important. This paper introduces a…

The effectiveness of mixed sensory mode presentation for beginning and experienced learners of Chinese characters as second language was investigated. Experiment 1 found that inexperienced 7th graders performed better on meaning recall in the mixed visual-audio mode than the visual mode presentation, but the superiority of these two formats was…
