Offers calculus students and teachers the opportunity to motivate and discover the first Fundamental Theorem of Calculus (FTC) in an experimental, experiential, inductive, intuitive, vernacular-based manner. Starting from the observation that a distance traveled at a constant speed corresponds to the area inside a rectangle, the FTC is discovered,…

Twelve middle school students, working in pairs, used a computer microworld to explore introductory geometric transformational concepts. Despite a tendency for symbolic overgeneralization, the students were able to use visual feedback from the microworld and discussions with partners to correct their own mistakes. (Author/JJK)

Discussion of computer simulations used for exploratory learning focuses on the design of a hypothesis scratchpad that students can use for hypothesis generation and testing. An experiment with college chemistry students that compared three versions of the scratchpad is described, and the effect of the scratchpads on learning environments is…

Presents seven scenes showing everyday classroom situations that give students the options of applying their own problem-solving strategies to solve everyday problems of life and enable them to experience mathematical power coming from self-initiated insights into mathematical concepts. (MDH)

This activity book for teachers and students presents ideas for lessons on Christopher Columbus. Three sections offer teaching ideas and student activities focusing on Columbus's inspiration and preparation for departure, the science of navigation and the voyage, and the pros and cons of changes brought about by Columbus's voyage. (SM)

Describes an inexpensive spectrum projector that makes high-dispersion, high-efficiency diffraction gratings using a holographic process. Discusses classroom applications such as transmission spectra, absorption spectra, reflection characteristics of materials, color mixing, florescence and phosphorescence, and break up spectral colors. (MDH)

Discusses "connectionism," an alternative learning model wherein meaning resides in the function of the whole state of a network, rather than being localizable in certain symbols or areas. Topics discussed include integration with other learning models; the culture of the mathematics classroom; and characteristics of alternative…

Discusses the use of the computer software MINITAB in teaching statistics to explore concepts, simulate games of chance, transform the normal variable into a z-score, and stimulate small and large group discussions. (MDH)

About 21% of all U.S. public school students attend schools equipped with multimedia computers, videodisc players, and other software designed to combine text, graphics, and sound in interactive applications. Multimedia software products can nurture the seven multiple intelligences identified by Howard Gardner, if properly implemented.…

Describes the Microworld Chance, a simulation-oriented computer environment that allows students to explore probability concepts in five subenvironments: coins, dice, spinners, thumbtacks, and marbles. Results of a teaching experiment to examine the effectiveness of the microworld in changing students' misconceptions about probability are…

Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Through a review of the literature, looks at instructional and curricular issues related to the student-as-scientist model and the critical nature of the teacher's role in expanding school science activities to include this model. (SM)

Explores the interrelationship between a conception of science teaching and the nature of a knowledge base for science teachers, outlining a history of curricular efforts in medical education. The article proposes a generative conception of science teaching and develops the role of three associated knowledge bases. (SM)

Examines changes in elementary science teachers' education, noting the fragmented status of school science. Few elementary teachers have strong academic backgrounds in science or fundamental knowledge of elementary science program content. Understanding preservice teachers' alternative conceptions and misconceptions about the nature of science is…

Describes a mathematics and science course designed to inspire early childhood education preservice teachers. They learn to interest young children by engaging in the kinds of science and math activities used with young children. These activities arouse feelings, stimulate curiosity, and offer opportunity for engagement. (SM)
