Discussion of students' understanding of illustrations in textbooks focuses on a British study designed to determine whether secondary school pupils could identify cut surfaces of objects in biological illustrations. Implications for theories of perceptual development and the role of illustrations in teaching are discussed, and further research…

Discusses some difficulties in teaching the concept of voltage to secondary school students. Presents and describes the content of a teaching sequence introducing voltage as a primary concept through relationships with other variables. Provides an example of the delivery of the teaching model. (YP)

Describes a laboratory explosion involving 30 percent hydrogen peroxide being heated on a ceramic-top hotplate. Gives three safety suggestions: peroxides should be treated as potential explosion hazards; alternatives to the ceramic-top hotplate for these reactions should be considered; and lab workers should be prepared for the worst possible…

Reports an experimental procedure for studying Einstein's theory of Brownian movement using commercially available latex microspheres and a video camera. Describes how students can monitor sphere motions and determine Avogadro's number. Uses a black and white video camera, microscope, and TV. (ML)

Examined whether and how the quality of students' explanations of chemical phenomena was affected by changing the method of giving the question and answer between the spoken and written formats. Concluded that there was no difference between the performance of students using any of these combinations of formats. (Author/YP)

This article presents a group project that uses math, science, and art to help elementary school students explore the tones of music in their own world. The children make music out of their own telephone numbers, create a soda bottle and drinking glass band, and graph their own telephone numbers. (SM)

Discusses the use of telecomputing in classrooms. Topics include telecomputing goals; use of the Internet; language arts and music FTP (file transfer protocol) sites; social studies FTP sites; science Telnet sites; social studies Telnet sites; skill building and learning processes; and instructional design. (LRW)

This article introduces a section with 100 innovative suggestions for creative activities that go across the curriculum and across grade levels and that are designed to hold students' enthusiasm. The activities are grouped by language arts, math, science, and social studies. (SM)

Describes a teacher education program designed to increase preservice teachers' confidence in their ability to instruct elementary children in hands-on science. (Author/MKR)

This study examined scientific problem finding behavior in 40 gifted rising sixth graders participating in a 1-week summer residential program. Some correlations were found between ability to form hypotheses and creativity. Comparison with a previous study done with ninth graders found significant differences between groups. No differences were…

Describes an activity where students research Native American and colonial uses of herbs, study herb folklore, and observe differences between herb seeds and plants. (PR)

Describes an activity where teams of parents and children work together to solve problems involving matchbox-sized race cars. The teams collect, record, and analyze data; measure distances in metric; and explore concepts related to mass, friction, and force. (PR)

A student laboratory exercise on the development of nutrient deficiency and toxicity symptoms was linked to analytical techniques and ion chemistry by having the students determine which ions in the nutrient solutions were missing or present in excess. (Contains 15 references.) (Author/MDH)

Reviews five computer programs that will give students the chance to start working cooperatively. Evaluates each program, and gives hardware requirements, cost, age range, supplemental materials available, and ordering information. (TM)

Discusses the Project 2061 benchmarks, statements of what all students should know or be able to do in science, mathematics, and technology by the end of grades 2, 5, 8, and 12. (MKR)
