Objective: Research on children's risk of injury reveals that parent and child factors are often interrelated. This study examined relations between children's risk taking, parent appraisal of this risk taking, and children's rate of injury in youth 8 and 9 years old. Methods: Responses to questionnaires and laboratory tasks were used to examine…

In a recent paper, Hu, Ericsson, Yang, and Lu (2009) found that an ability to memorize very long lists of digits is not mediated by the same mechanisms as exceptional memory for rapidly presented lists, which has been the traditional focus of laboratory research. Chao Lu is the holder of the "Guinness World Record" for reciting the most decimal…

Laboratory studies on a range of animals have identified a bias that seems to violate basic principles of rational behavior: A preference is shown for feeding options that previously provided food when reserves were low, even though another option had been found to give the same reward with less delay. The bias presents a challenge to normative…

Reports of exaggerated anxiety and physiological hyperreactivity to social-evaluative situations are characteristic of childhood social phobia (SP). However, laboratory research on subjective, autonomic and endocrine functioning in childhood SP is scarce, inconsistent and limited by small sample sizes, limited breadth of measurements, and the use…

A simple benchtop experiment in which a moving cart collides with a fixed spring is described. Force-time and force-distance data recorded during the collision display the transit of compression wave fronts through the spring following impact. These data can be used by students to develop a computational model of the dynamics of this simple…

Elementary school students are intensely curious about astronomy: the Moon, planets, stars, and galaxies. Summer, with its warm evenings and star-filled skies, is the perfect time for students to explore the cosmos with a pair of binoculars. Because binoculars are used for many purposes (sporting events or birding, for example), many families…

The writing center where the authors were trained and currently work emphasizes the model of non-directive, writer-based peer tutoring in which, as Jeff Brooks puts it, tutors "make the student the primary agent in the writing center session." As undergraduate peer tutors, they recognize that some students come into their writing center with goals…

Neuroscience exploded into the education conversation more than 20 years ago, in step with the evolution of personal computers and the rise of the Internet, and policymakers hoped medical discoveries could likewise help doctors and teachers understand the "hard wiring" of the brain. That conception of how the brain works, exacerbated by the…

Purpose: Sustainability initiatives typically operate for a limited time period, but it is often unclear whether they have lasting effects. The purpose of this paper is to examine a laboratory fume hood campaign, in order to identify factors that might contribute or detract from long-term change persistence. Design/methodology/approach: The…

Normally, a mechanics laboratory at the undergraduate level includes an experiment to verify compliance with Hooke's law in materials, such as a steel spring and an elastic rubber band. Stress-strain curves are found for these elements. Compression in elastic bands is practically impossible to achieve due to flaccidity. A typical experiment for…

The development of the Child Study Centre (CSC) at University of British Columbia (UBC) provides a unique perspective on the complex and often contradictory relationship between child study and preschool education in postwar Canada. In this article, the authors detail the development and eventual closure of the CSC at UBC, focusing on the uneasy…

Engaging students in a predator-prey simulation to teach natural selection is a common activity in secondary biology classrooms. The purpose of this article is to demonstrate how the authors have changed their approach to teaching this activity from a laboratory investigation to a class-constructed simulation. Specifically, the authors drew upon a…

The way an animal moves from place to place can inform us about its life and environment. In this lesson, students examine the travel patterns of juvenile flatfishes in an estuary. The process of sampling bottom-dwelling fishes is explained, and data from a university-based marine science laboratory are evaluated. Students compare the distance…

Undergraduate research experiences confer benefits on students bound for science, technology, engineering, and mathematics (STEM) careers, but the low number of research professionals available to serve as mentors often limits access to research. Within the context of our summer research program (BRAIN), we tested the hypothesis that a team-based…

This white paper describes instructional approaches that apply to successful teaching with the Smithsonian "Learning Lab." After defining its use of terms such as "deeper learning" and "authentic resources" the authors review the research basis of three broad approaches that support integrating digital resources into…
