Describes a framework for the construction of computer-aided learning programs and for the BBC microcomputer which has been used successfully as the basis of a set of genetics teaching programs called "Linkage." Includes program design principles and procedures. (ML)

Surveys the present status of science instructional software in the United States. Describes project efforts at the University of Pittsburgh on the development of intelligent tutoring systems (ITS). Explains the major components and provides microworld examples of ITS. Includes the software evaluation instrument and summarizes the evaluation…

Describes a new software package for the Apple Macintosh computer which can be used to create elaborate simulation models in a fraction of the time usually required without using a programming language. Illustrates the use of the software which relates to water usage. (TW)

This study investigated the influence of scaffolds on prospective teachers'(PTs') construction of scientific arguments. Participants were enrolled in an innovative science course aimed at providing PTs with experiences learning science using inquiry empowering technologies. PTs' arguments were constructed within the context of a light unit in…

This paper describes changes in students' ideas about science classes, attitudes about science, and motivations for studying science in a classroom designed to support project-based science learning. Findings indicate that providing students with opportunities to collect and analyze their own data in science classes results in a change in…

This document presents an integrated unit plan on snakes targeting second grade students. Objectives of the unit include developing concepts of living things, understanding the contribution and importance of snakes to the environment, and making connections between different disciplines. The unit integrates the topic of snakes into the areas of…

Learner-centered software design (LCSD) guides the design of tasks, tools, and interfaces in order to support the unique needs of learners: growth, diversity and motivation. This paper presents a framework for LCSD and describes a case study of its application to the ScienceWare Model-It, a learner-centered tool to support scientific modeling and…

College courses that are taught without any technology are part of the past. With software that can do almost any mathematics including calculus, traditional teaching, with the instructor as all-knowing, is obsolete. In this paper, a comparison is made between business mathematics courses and general physics courses taught at a small private…

This digest presents an overview of ways that parents can encourage their child's learning in science. National and state standards for science knowledge and skills are discussed. The importance of parental guidance and encouragement in all subjects--science in particular--is also discussed. Suggestions are made for setting a good example, helping…

Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve.…

Describes a science project at Booker T. Washington Middle School #54 (New York City) where seventh and eighth graders computed the Hudson River's water quality using ClarisWorks spreadsheets and MicroWorlds software. Students gained technology skills and public recognition, as well as scientific and environmental information. Includes sample…

Examines a lesson in which students are engaged in inquiry in evolutionary biology to develop better understanding of concepts and reasoning skills necessary to support knowledge claims about changes in the genetic structure of populations known as microevolution. Explains how a software simulation, EVOLVE, can be used to foster discussions about…

The theory of multiple intelligences (MI) allows teachers to tap into the strengths of each student and to develop capabilities in novel ways. By weaving together technology, MI, and curriculum, the Hemenway public elementary school (Framingham, Massachusetts) helps students work in their own "magical learning environment" and accomplish the…

Described is a series of computer tutorials developed to teach students a logical method of problem solving for chemistry. The structure, pedagogy, and problem-solving strategies of the computer software program are described. (CW)

Described are the uses of a spreadsheet program to compute the free energy change associated with a reaction; to model acid/base equilibria; and to solve equilibrium constant expressions. Stressed are the advantages derived from having the spreadsheet perform the multiple, trivial calculations. (CW)
