Describes chemistry software that is part of a balanced educational program. Provides several applications including graphs of various relationships among the elements. Includes a brief historical treatment of the periodic table and compares the traditional historical approach with perspectives gained by manipulating an electronic database. (DDR)

Describes how the tapping of maple trees can be used to teach lessons in science on boiling points, density, solubility, and other sugaring projects in the curricula. Outlines activities and precautions to follow when doing this project. (RT)

Describes a program which allows students to identify and characterize several kinetic inhibitory mechanisms. Uses the generic model of reversible inhibition of a monosubstrate enzyme but can be easily modified to run other models such as bisubstrate enzymes. Uses MS-DOS BASIC. (MVL)

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

Using Piagetian tasks designed to assess specific mental structures, researchers investigate the relationship between logical thinking structures and the ability of students to construct and interpret line graphs. Results revealed that a significant correlation exists between the aforementioned variables. Suggests and cautions that only at certain…

Microcomputer-based laboratories (MBLs) are believed to have significant potential for improving laboratory experiences in science classrooms. A study funded through a grant project called STEPS to Better Science sought to broaden the knowledge base by examining MBL use by teachers and students in a variety of science classrooms in six high…

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

Discusses a study which assessed the effect of a brief kinematics unit on: (1) students' ability to translate between a physical event and the graphic representation of it, and; (2) the effect of real-time on graphing skills. Reports the success of the use of a microcomputer-based laboratory with graphing velocity and distance. (ML)

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

Presents abstracts from the National Educational Computing Conference held in Dallas, Texas on June 15-17, 1988. Selected topics include: a physical science interactive videodisc project, impact of calculators and computers in secondary math, relationships between graphing and functions, effectiveness of computer use, training science teachers,…

Discusses the use of graph theory to aid in the depiction of organic molecular structures. Gives a historical perspective of graph theory and explains graph theory terminology with organic examples. Lists applications of graph theory to current research projects. (ML)

Describes a software library developed to teach biophysics and physiology undergraduates that includes software on (1) the Hodgkin-Huxley model for excitation of action potentials in electrically excitable cells; (2) a random-walk model of diffusion; (3) single voltage-gated ion channels; (4) steady-state chemically mediated transport; and (5)…

As part of an investigation of the effectiveness of a microcomputer-based laboratory (MBL) activity in developing students' graphing skills, this study was specifically designed to examine the differences between females and males in both performance on graphing tasks and on their attitudes to graphs and graph-based activities. Results based on a…

This publication provides information and activities for teaching about vegetables and process skills including observing, classifying, collecting and interpreting data, inferring, measuring, and predicting. There are 12 lessons. Lessons 1 through 5 pertain to growing, rinsing, and observing sprouts. Lessons 6 and 8 through 11 deal with tasting…

A 3-year study was conducted to determine the logical reasoning processes necessary to construct line graphs. Responses obtained from middle and high school science and mathematics students were classified into one of nine categories. These categories ranged from "no attempt to make a graph" to "complete graph with a statement of a…
