Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

Describes: Apple stereochemistry program; CNDO/2-INDO mini-computer calculations; direct linear plot procedure for enzyme kinetics calculations; construction of nonlinear Scatchard plots; simulation of mass spectral envelopes of polyisotopic elements; graphics with a dot-matrix printer; MINC computer in the physical chemistry laboratory; hallway…

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)

Describes instructional development process applied to the design, production, implementation, and evaluation of a computer simulation designed to provide troubleshooting practice for individuals who maintain and install large digital telephone switches. The major organizational benefits resulting from use of the simulation are discussed. (MBR)

Describes technique involved in designing a clinical simulation problem for the allied health field of respiratory therapy; discusses the structure, content, and scoring categories of the simulation; and provides a sample program which illustrates a programming technique in BASIC, including a program listing and a sample flowchart. (MBR)

Describes a sequence of five computer programs (listings for Apple II available from author) on tactic responses (oriented movement of a cell, cell group, or whole organism in reponse to stimuli). The simulation programs are useful in helping students examine mechanisms at work in real organisms. (JN)

Examines educational technology (EdTech) in Florida using the future-is-here-now technique, suggesting transposition of teaching/learning, rezoning research, and elasticizing experience. Scenarios are provided to illustrate computer-enhanced collaborative learning, electronic messaging (teleconferencing) and simulation or interactive gaming. (JN)

In computer-based simulations, students must bring a wide range of relevant knowledge, skills, and abilities to bear jointly as they solve meaningful problems in a learning domain. To function effectively as an assessment, a simulation system must additionally be able to evoke and interpret observable evidence about targeted knowledge in a manner…

This study compared the performance of the LOGIST and BILOG computer programs on item response theory (IRT) based scaling and equating for the Test of English as a Foreign Language (TOEFL) using real and simulated data and two calibration structures. Applications of IRT for the TOEFL program are based on the three-parameter logistic (3PL) model.…

This paper focuses on one method used to introduce model design and creation using StarLogo to a group of high school teachers. Teachers with model-building skills can easily customize modeling environments for their classes. More importantly, model building can enable teachers to approach their curricula from a more holistic perspective, as well…

For colleges/universities, rapid instrument development poses a dilemma, since laboratory teaching instruments rapidly become obsolete and money available for replacing them is dwindling. Discusses role of sophisticated computer simulations, nontraditional educational materials, and part-time work-study opportunities as possible solutions to the…

Discusses the use of a computer simulation program in teaching the concepts of spectrophotometry. Introduces several parts of the program and program usage. Presents an assessment activity to evaluate students' mastery of material. Concludes with the advantages of this approach to the student and to the assessor. (ASK)

Investigated second graders' ability and motivation to create and manipulate simulations using KidSim software. Found that using KidSim was a motivating experience and the students were able to develop complex simulations. The dominant motivational factors were the freedom to create original characters and the rules to direct them. Other…

Evaluates the importance of realism in the screen presentation of the plant in computer-based laboratory simulations for part-time engineering students. Concludes that simulations are less effective than actual laboratories but that realism minimizes the disadvantages. The schematic approach was preferred for ease of use. (AIM)
