Describes hardware and software requirements for interfacing a thermometer probe, via an analog and digital converter, to any Commodore PET, VIC-20, or Commodore-64 microcomputer (or other microcomputers with some modifications). Also describes use of the probe in an experiment measuring enthalpies of reaction to determine enthalpy of formation of…

Provides abstracts of selected papers presented at EdCompCon '84. Topics addressed include: what features educators want in educational software; effects of teaching method on student performance by sex in a computer literacy course; implementation and evaluation of a university microcomputer laboratory; and implementation and evaluation of PLATO…

Presents background information and the listing for a LOGO computer program which investigates an ancient mathematical riddle (related to the square root of seventeen). The simulation, written for Apple II microcomputers, can be easily adapted to other microcomputers. (JN)

Examines various types of software useful in teaching about nuclear energy. Includes a list of 11 software resources (including program name, source and cost, system requirements, and brief comments about the program). (JN)

Correlations derived from this study indicate that undergraduate students' (N=24) and graduate students' (N=18) performance in statistical methods is not strongly influenced by their aptitude in computer science. One implication is that no computer science prerequisite is necessary for courses utilizing statistical packages. (JN)

Describes a system in which the computer, by interacting with an information bank, produces an individual or group diagnostic profile specifying the nature of the factors that contribute to mathematics difficulties and student variability. The computer also generates suggestions for remediating the learning difficulties and accommodating student…

Examines human-computer interaction from two views of cognition: the representationist view and the enactivist perspective. A chaos-theory context is discussed from an enactivist stance. In this context, high school students manipulate nonlinear dynamic computer programs. Implications of the enactive stance for education and research are also…

Described is an approach to computational matrix algebra that takes advantage of a high quality, low cost microcomputer software package. The examples and applications discussed focus on matrix multiplication. (Author/CW)

This article presents a technique that builds linear equations to approximate Fry's readability graph. A BASIC program building the linear equations and providing the grade levels is provided. (Author/YP)

This article utilizes several examples to describe the use of MathCAD, a computer scratchpad for calculations, within a lecture-demonstration method of teaching general calculus. Both hardware requirements and software features are discussed specifically related to the proper design of student worksheets with emphasis on parameter variation. (JJK)

Examples of subroutines that generate both symbolic and graphic solutions to differential equations are presented for the two computer algebra systems, MAPLE and Mathematica. Included are the listings for the Mathematica procedures developed for use in this article. (JJK)

High school biology students (n=261) completed 1 of 4 versions of the hypermedia courseware, "The Ecology and History of the Great Smoky Mountains National Park." Analysis failed to detect any statistically significant differences in achievement among the four groups, but did detect a significant difference among student ability levels. Supports…

Surveyed currently available software in the physical sciences, biological sciences, and earth/space sciences. Also examined interdisciplnary and remedial programs. One finding is that the emphasis in science education software is for high school and college students with little software for junior high school teachers or students. (JN)

Describes several exemplars of software that emulate and incorporate machine-supported aspects of cognitive apprenticeships in science and mathematics. Concludes with an evaluation of software against cognitively guided principles and with a summary of the difficulties associated with creating and implementing machine-supported apprenticeships.…

Provides the results of a survey of science teachers (n=635) regarding the status of computer use and professional development needs related to the use of computers in classrooms. Results indicate that 91% of the classrooms have computers. Professional development needs are categorized by groups: non/past users, novices, and users/experts. (DDR)
