Six studies discussed in this paper compared error-specific or model-based remediation (MBR) with reteaching in algebra. MBR points out, and highlights as incorrect, errors specific to the student's solution before reteaching the correct procedures. Reteaching shows the student the correct procedure without addressing specific errors. Three of…

This paper provides an overview of the four major aspects of the PIXIE Intelligent Tutoring System: the field work undertaken to determine how teachers diagnose and remediate in introductory algebra; the set of experiments run to determine the relative effectiveness of Model-Based-Remediation (MBR) and Reteaching; systems work carried out to…

This material describes a sequence of inquiry-based instruction with Logo that is designed to teach young children (fourth grade or younger) about pre-proof geometry. Pre-proof geometry includes concepts such as open versus closed paths, angles, lines, polygons, and relations among polygons. Inquiry-based instruction relies upon questions to help…

A survey of 112 teachers working in 26 schools in six districts within a regional area was conducted to investigate microcomputer use by teachers. The survey instrument included items on personal characteristics, years of teaching experience, current use of computers in the classroom, confidence in personal ability to use computers, and perception…

This project developed a lesson authoring system, a component which provided communications between students and teachers using electronic mail, and calculus lessons which were formatively evaluated with 20 students at four high schools. The authoring system utilized word processors to write the lessons and a BASIC computer program to execute the…

This guide explains ways in which the computer can be used in the science classroom and laboratory. Further, it suggests many resources that can be tapped to help teachers initiate and improve their own programs. Chapters include: (1) "The Computer as a Tool for Student Inquiry"; (2) "The Computer as a Tool for Teachers"; (3)…

The purpose of this study was to determine whether an electronic geoboard, a computer-software program, could be used to assess youngsters' ability to discover facts and relationships in an unlabled and ambiguous situation. Subjects--108 children, ages 6 to 12--were enrolled in grades 1 to 6 in Norwood, New York. The electronic geoboard served as…

Use of a computer programming language in problem-solving activities provides an opportunity to examine how young children use a restricted set of language primitives. The generation, and execution of computer instructions was used as a verification stage in the problem-solution process. The metric is intended to provide a descriptive…

There is a host of research examining the equivalence of alternative modes of technology-facilitated educational delivery (such as computer-based or online instruction) and traditional classroom instruction. While various studies have promoted each of these modalities for specific populations or topic areas, the bulk of research supports relative…

Declares the need to train teachers to use computers in reading and language arts and describes a training program used with undergraduate education majors at the State University of New York at Geneseo. (SRT)

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Reports on an experiment which used computer games to increase the efficiency of information processing and concentration skills among learning disabled (LD) children. Results showed that computer games presented within the framework of self-verbalization procedures and peer-interaction facilitated the information processing of LD children.…

This study investigated the effectiveness of computer simulations for enhancing the problem solving skills of high school students. Summaries of three related studies are presented. Results indicate that the computerized simulations enabled students to master the objectives of a biology course as effectively as traditional methods. (ML)

The author argues the necessity of ensuring that mathematics is perceived by children as being useful. An example is provided which is intended to give children experiences which might help them develop a rationale for learning. It involves an item of computer software which simulates car racing.
