At the national level, obesity and obesity-related illnesses are increasing dramatically. As with many other public health problems, some racial and ethnic populations are disproportionately affected. This article presents current information on the prevalence and consequences of obesity for racial and ethnic groups in the United States and…

Evolution is the cornerstone of biology and one of the most powerful, exciting, and well-supported laws in modern science. Evolution transforms biology from a collection of unrelated observations and definitions into a coherent discipline that, among other things, helps people understand life's history and predict answers to important research…

The Howard Hughes Medical Institute (HHMI) believes that fundamental change is possible in the tradition-bound world of college and university science education and recently announced new grants to empower individual scientist-educators--the HHMI Professors--to develop innovative approaches for changing the way they teach biology to…

To help students develop successful strategies for learning how to learn and communicate complex information in cell biology, we developed a quarter-long cell biology class based on team projects. Each team researches a particular human disease and presents information about the cellular structure or process affected by the disease, the cellular…

This study was aimed at sorting out conflicting results in the literature concerning 2-month-olds' sensitivity to interpersonal contingency, and investigated the potential role of infants' positive emotion in contingency detection. Infants were randomly assigned to an experimental group (EG) that was presented an uninterrupted live-replay-live…

Classroom demonstrations are a great vehicle for getting students to apply information they have heard in a lecture. Educational research is replete with data showing that concept application in an inquiry setting reinforces long-term science content retention. This means that students learn best when they experience applications of concepts and…

Astrobiology is an interdisciplinary science course that combines essential questions from life, physical, and Earth sciences. An effective astrobiology course also capitalizes on students' natural curiosity about social science implications of studying the origin of life and the impact of finding life elsewhere in the universe. (Contains 2…

This study examined operational data from the SAT Reasoning Test™ to determine if students who tested under extended-time conditions were suffering from excessive fatigue relative to students who tested under standard-time conditions. Excessive fatigue was defined by significant (a) increases in differential item functioning (DIF) and (b)…

There has been considerable interest recently in the teaching of skills to undergraduate students. However, existing methods for collating data on how much, where and when students are taught and assessed skills have often been shown to be time-consuming and ineffective. Here, we outline an electronic research skills audit tool that has been…

This curriculum guide is the second (Series II) in a six-volume set that comprises the Sea Week Curriculum Series developed in Alaska. This second book in the series lends itself to the first-grade level but can be adapted to preschool, secondary, and adult education. Nine units contain 30 activities with worksheets that cover the following…

These proceedings report the efforts of National Science Foundation researchers to disseminate innovations in undergraduate education. Section 1 contains forewords and keynote addresses by Robert F. Watson, Neal F. Lane, and Luther S. Williams. Section 2 contains overviews on dissemination and publishing including "Full-Scale Implementation: The…

This curriculum guide accompanies Certified: A Citizen's Step-by-Step Guide to Protecting Vernal Pools which is designed to train volunteers in the process of identifying vernal pool habitat so that as many of these pools as possible can be certified by the Massachusetts Natural Heritage and Endangered Species Program. Vernal pools are a kind of…

Visual learning has long been recognized as an integral process in educating biology undergraduates, who must develop specific visual skills and knowledge in order to communicate and work in the extensive visual culture shared by practicing biologists. Student experiences with field observations and the development and application of verbal/visual…

This instructor guide and the corresponding student reference contain 4 units that include 30 lessons for a course in animal science for 11th- and 12th-grade agriculture science students. The units cover nutrition, genetics, reproduction, and animal health. The instructor's guide contains the following: objectives, competencies, motivational…

This paper investigates the thematic study approach in theory and practice as it applies to the elementary grades, specifically to third grade. Part 1 defines the theme study approach and explains the theories and assumptions that support it as a viable approach to teaching and learning. Part 2 examines research supporting the thematic approach.…
