Describes a successful effort by an elementary school and community to convert a classroom into a school science laboratory and stock the laboratory with science materials and apparatus. (PR)

Capitalizing on the research skills of the faculty, the introductory chemistry course at the College of the Holy Cross (Massachusetts) invites students to participate in the processes of speculation, investigation, and discovery, using a laboratory-based curriculum that emphasizes the scientific method. (Author/MSE)

The Highland School, located in the remote hills of West Virginia, is modeled on John Dewey's ideas. This laboratory school promotes experiential learning and believes that interaction between children, teachers, and the environment is the key to learning. The article describes the schools' founding and the philosophy behind it. (SM)

Examines the following questions related to the effectiveness of science laboratory activities: (1) the behavior of high school chemistry teachers; (2) the behavior of high school chemistry students; and (3) the relationship, if any, between teacher behavior and student behavior as exhibited during high school chemistry laboratory sessions. (LZ)

Describes a simple, safe, and inexpensive hands-on demonstration of normal and abnormal coagulation using bovine blood plasma. (JRH)

Describes a literacy program for three- and four-year-old children established in a university setting to provide teacher education students an opportunity to read with the children while emphasizing concepts about print. Finds a slight increase in the children's concepts about print and in their familiarity with books. (SR)

Describes new software called "PopGenetics" that is useful for conducting hands-on laboratory activities that illustrate population genetics. Users investigate the effects of selection and random drift on changes in allelic frequencies, the effect of mutation, and interactions among these three parameters. Designed for use on Macintosh…

Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…

The Center for Instructional Technology and Training was created by the Washington, DC, public schools in 1983 to provide inservice technology training free of charge to teachers, administrators, and clerical and building staff. The development of the successful program is described and sidebars report what teachers and principals say about it and…

Presents five puzzles in the shape of stars that contain scrambled letters and clues to help define computer terms and improve computer literacy. Use of the puzzles by students and adults in the computer labs of library media centers is discussed. Answers to the puzzles are also provided. (LRW)

The Family/School/Community Participation Project restructured Florida State University's affiliated K-12 school through three phases: (1) School as Family, preparing teachers and administrators to create a supportive school environment; (2) Family Outreach, involving the school in helping families with a supportive home environment; and (3)…

Inexpensive metal probe meters that are sold by garden stores can be evaluated by students for their accuracy in measuring soil pH, moisture, fertility, and salinity. The author concludes that the meters are inaccurate and cannot be calibrated in standard units. However, the student evaluations are useful in learning the methods of soil analysis…

The relationship between process and content in children's science learning is discussed. The idea that both aspects are important in learning, especially during practical investigations, and that both should be emphasized are presented. (KR)

Describes an activity in which students investigate the effects of selected natural and synthetic substances on the rate of apple browning. Includes background information for the teacher, a list of necessary materials, and student instructions. (KR)

Describes a method for identifying and examining single ice crystals by photographing a thin sheet of ice placed between two inexpensive polarizing filters. Suggests various natural and prepared sources for ice that promote students' insight into crystal structures, and yield colorful optical displays. Includes directions, precautions, and sample…
