This paper summarizes the recent work of the Maryland Physics Education Research Group on analyzing student learning in introductory university physics. This work is carried out in a model of student thinking and learning based on principles from cognitive science. The model permits a better understanding of, and diagnosis for, the state of both…

In this activity, students design and create a LEGO (plastic building blocks) structure to house and protect a temperature sensor. The structure is left in a safe spot and the temperature is regularly checked and charted. This activity uses a time frame of 45 minutes. (Author/SOE)

"Bug City" is a video series created to help children learn about insects and other small critters. All aspects of bug life are touched upon including body structure, food, habitat, life cycle, mating habits, camouflage, mutualism (symbiosis), adaptations, social behavior, and more. Each program features dramatic microscopic photography,…

Ranger Rick's NatureScope is a creative education series dedicated to inspiring in children an understanding and appreciation of the natural world while developing the skills they will need to make responsible decisions about the environment. Contents are organized into the following sections: (1) "What Makes a Dinosaur a Dinosaur?,"…

This chemistry textbook presents a beginning course for schools or colleges. It presents a more complete classification than usual according to chemical analogies, the explanation of chemical phenomena in ordinary language, as well as symbols, and the addition of a complete set of formulae in the appendix. A number of recent and important…

This chemistry textbook presents a beginning course for schools or colleges. It presents a more complete classification than usual according to chemical analogies, the explanation of chemical phenomena in ordinary language, as well as symbolic language. A series of new and original designs are introduced, illustrating to the eye the groupings of…

Discusses experience of teaching a "Search in Science" course to college nonscience majors entitled "From Myth to Mechanism: A Study of Man's Changing Concepts of the Universe from Early Mythological Beliefs to the Development of Modern Scientific Laws." Historical explanation of the development of physical concepts is stressed. (CC)

Reviews theoretical principles underlying the quark model. Indicates that the agreement with experimental results and the understanding of the quark-quark force are two hurdles for the model to survive in the future. (CC)

Discusses scientific information obtained from Pioneer 10's Jupiter flyby and the comet Kohoutek's first trip around the sun, including the high hydrogen emission of Jupiter's principal moon, Io. (CC)

Discusses an experiment which introduces students to the effects of electrical forces on the motion of macroscopic objects. Included are the proecedures of measuring the charge-to-mass ratio from deflections of charged water drops in horizontal fields and the overall charges delivered in a Faraday cup. (CC)

Describes how the use of model rockets can be used to stimulate student interest and facilitate the learning of many science and mathematics concepts. (JR)
