Hunting Bears with a Microscope
In this online activity, students use lichens and tardigrades (water bears) to investigate their use as bioindicators of key air pollutants. When lichens are exposed to some kinds of air pollutants, especially to sulfur dioxide, the lichens are injured and die. The lichen coverage in a specified area should be a good indicator of the level of air quality. The diversity of the tardigrade species on the lichens will be used to develop another level for bioindication of air quality. Sections of thi
Addition and Subtraction Face-Off! Game
Students place markers on the numbers 2-12. Students toss two 6-sided dice, find the sum and remove a marker from that number, if there is still one. The first player to remove all markers wins the game. This game can be used as addition practice or as an introduction to the probability of the different outcomes of rolling two dice. This game was developed by a Monmouth University student for the Probability Fair. These games help students acquire proficiency in addition and subtraction facts.
Genetic Disease WebQuest
Students take on different roles to learn about DNA and genetic diseases, including how a genetic disease causes a person to get sick, how we test for and treat a genetic disease, and how we help people to make better decisions regarding all the complicated issues involved with genetic diseases. This webquest, designed for high school and undergraduate students, is an ideal introduction to the concepts of bioinformatics, genetic diseases, and potential careers in science fields. The activity can
Two Unreconciled Strivings: African-American Identity in the Gilded Age, 1877-1915
Examine the tension experienced by African-Americans as they struggled to establish a vibrant and meaningful identity based on the promises of liberty and equality in the midst of a society that was ambivalent towards them and sought to impose an inferior definition upon them. The primary sources used are drawn from a time of great change that begins after Reconstruction's brief promise of full citizenship and ends with the First World War's Great Migration, when many African-Americans sought gr
Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
Fundamentals of Program Evaluation
Fundamentals of Program Evaluation familiarizes students in different types of program evaluation, including needs assessment, formative research, process evaluation, monitoring of outputs and outcomes, impact assessment, and cost analysis. Students gain practical experience through a series of exercises involving the design of a conceptual framework, development of indicators, analysis of computerized service statistics, and development of an evaluation plan to measure impact. This course cover
Introduction to Methods for Health Services Research and Evaluation
Introduction to Methods for Health Services Research and Evaluation provides an introduction to basic methods for undertaking research and program evaluation within health services organizations and systems. In addition to basic methods, the course also provides "the state of the art" in research and evaluation through the review of major completed studies. This course is recommended for students who will be carrying out policy research, social science research, or program impact evaluation with

The Secret World of Sharks and Rays
Woldwide, there are more than 370 species of sharks, which vary greatly in size, shape, preferred habitat, and prey. This film from the PBS Nature series explores their worlds and those of their close cousins, the rays. (49:36)
Semi-Riemann Geometry and General Relativity
This book represents course notes for a one semester course at the undergraduate level giving an introduction to Riemannian geometry and its principal physical application, Einstein’s theory of general relativity. The background assumed is a good grounding in linear algebra and in advanced calculus, preferably in the language of differential forms. This book covers the following topics: The principal curvatures; rules of calculus; Levi-Civita Connections; bundle of frames; connections on prin
Introduction to Computer Science I
Computer Science 50: Introduction to Computer Science I is a first course in computer science at Harvard College for concentrators and non-concentrators alike. More than just teach you how to program, this course teaches you how to think more methodically and how to solve problems more effectively. As such, its lessons are applicable well beyond the boundaries of computer science itself. That the course does teach you how to program, though, is perhaps its most empowering return. With this skill
Cosmic Survey: What are Your Ideas About the Universe?
Lesson plans and activity composed of a three-part questionnaire that launches students on discussions about where objects in space are located, and when they were formed- an introduction to the concepts of structure and evolution of the universe. This astronomical image-sorting activity lays the groundwork for discussions about the size, scale and history of the universe. Use it as a front-end assessment of how students understand the universe. Recommended for teachers of Grades 6-12 and inform
Most Internet content today is "served" from a central system that takes requests from a user's "client." Typically, the user asks for access to information or other data; the requested content is then "pushed" from the central system to the user. In this model, the various visitors to a given web site do not interact. By contrast, peer-to-peer technology (commonly known as "P2P") creates conversations among individual personal computers (PCs). In this respect, P2P systems resemble an affili
