Described are several activities for teaching children to determine mass and volume. Included are the masses of a water drop and a grain of rice; the volume of a water drop and small solids; and measuring the width of a hair. Procedures and materials for the activities are discussed. (CW)

Describes and evaluates science teachers' implementation of microcomputers at a field-test site that was part of a program to encourage literacy of science teachers in the use of microcomputers (ENLIST-Micros). Discusses why only 33 percent of the teachers used computers one year after the training. (Author/YP)

Discusses image scanning and optical character recognition. Describes how computer scanners work. Summarizes scan quality, scanning speed requirements, and hardware requirements for scanners. Surveys the range of scanners currently available. (MVL)

Three computer programs for the Apple II family are reviewed: (1) "Super Vocab Machine"--vocabulary self-tutorial; (2) "Elements, Compounds, and Mixtures: A Matter of Mystery"--database for the elements; and (3) "That's Life: Human Body Exploration"--information about the human body. (MVL)

Introduces the 1988 IBM/Classroom Computer Learning teacher of the year. Explores some of his teaching methods and ideas. Discusses his winning project of having students do research projects using a modem hookup to CompuServe. (MVL)

Introduces three different techniques to facilitate the measurement of speed and the associated kinematics and dynamics using a computer. Discusses sensing techniques using optical or ultrasonic sensors, interfacing with a computer, software routines for the interfaces, and other applications. Provides circuit diagrams, pictures, and a program to…

Outlines steps suggested by Education Secretary William J. Bennett to improve science curriculum. Lists topics of concern for grades K-8. (ML)

Reviews the chemistry computer database program "KC? Discoverer" from Project SERAPHIM. This program enables the user to look at chemical, physical, and microscopic properties of each element. Lists other available program options as FIND, GRAPH, LIST elemental properties, and SORT. Describes hardware requirements. (ML)

Lists the 12 minimum safety guidelines for chemical demonstrations as adopted by the Chemical Education division of the American Chemical Society. (ML)

Describes a partnership between business, public schools, and a university to empower high school math and science teachers to use multimedia workstations and other technology to improve their curricula. Improvements included more student-centered classrooms, as well as better feedback, problem solving, creativity, and motivation. Teachers were…

Examines similarities and differences between the experienced and novice science teachers' (n=23) pedagogical content knowledge with respect to demonstration teaching. Concludes that experienced demonstrators have a broader understanding for chemical demonstration teaching than do novices. Suggestions are made to assist novice teachers in…

Presents the science demonstration assessment as an authentic- assessment technique to assess whether students understand basic science concepts and can use them to solve problems. Uses rubrics to prepare students for the assessment and to assign final grades. Provides examples of science demonstration assessments and the scoring of rubrics in the…

Data from 5,065 Dutch ninth grade students participating in the Second International Science Study were analyzed to assess gender differences in achievement, attitudes, and perceptions of science. Significant sex differences found were effectively portrayed using a model developed by J. S. Eccles (1987). (TJH)

Methods for and results of implementation in the United States of the Second International Science Study's (SISS) advanced-science subsample are discussed. Analyses of student, teacher, and school effects on achievement in advanced biology, chemistry, and physics results are included. American students scored among the lowest four SISS…

Investigates the relevance and concomitant impact of sociocultural experiences upon the scientific literacy of 87 students, aged 13 to 16, concerning their comprehension and assimilation of scientific data involving solar eclipses. Results indicate that the students' nonscientific conceptions about solar eclipses, generated through sociocultural…
