The effects of limiting the availability of immediate feedback while using LOGO were studied for 48 students aged 9 to 11 solving rotation problems. Limiting feedback reduced the incidence of trial and error strategies, and higher level problem solving strategies were apparently used to compensate for the restricted feedback access. (SLD)

Summarizes recent advances in computer simulation and "reverse engineering" technologies, highlighting the Human Genome Project to scan the human genetic code; artificial retina chips to copy the human retina's neural organization; high-speed, high-resolution Magnetic Resonance Imaging scanners; and the virtual book. Discusses…

Instruction in computer-based business communication is vital to prepare students for the current environment. Course design should include hands-on training using electronic messaging, a simulated environment in which to practice networking, and encouragement of teams and collaboration among students. (SK)

Business students involved in group presentations (n=28), industry research projects (n=44), and computer simulation (n=51) rated each method on 10 criteria: interest, novelty, motivation, effort, business relevance, major relevance, course relevance, course improvement, learning, and difficulty. Simulation scored highest on 6 of the 10 areas. (SK)

The analysis of contingency tables via set correlation allows the assessment of subhypotheses involving contrast functions of the categories of the nominal scales. The robustness of such methods with regard to Type I error and statistical power was studied via a Monte Carlo experiment. (TJH)

Computer simulation is an ideal framework to encourage decision making, active learning, and motivation. Appropriate software should be judged in terms of realism, relevance, complexity, interface, administrative efficiency, and use of microcomputers. (SK)

Describes step-by-step techniques that can be used to develop educational simulations for undergraduate biology students. Also discussed are simulations that are currently being developed with the support of the National Science Foundation. (ZWH)

A new approximation is proposed for testing the equality of "k" independent means in the face of heterogeneity of variance. Monte Carlo simulations show that the new procedure has nearly nominal Type I error rates and Type II error rates that are close to those produced by James's second-order approximation. (SLD)

A complete enumeration method and a Monte Carlo method are presented to calculate the probability distribution of arbitrary statistics of adjacency matrices when these matrices have the uniform distribution conditional on given row and column sums, and possibly on a given set of structural zeros. (SLD)

A variety of paired comparison, triple comparison, and ranking experiments are discussed as generalized linear models. All such models can be easily fit by maximum likelihood using the GLIM computer package. Examples are presented for a variety of cases using GLIM. (SLD)

Reviews the literature dealing with the role of computers in psychiatric interviewing, and with the role of the computer as a patient or as a therapist. Efforts to develop forms of computer-assisted therapy are described, and implications for the mental health field are suggested. (40 references) (LRW)

Results of a Monte Carlo study with 4 populations (3,072 conditions) indicate that when distributions depart markedly from normality, nonparametric analysis and parametric analysis of transformed data show superior power to parametric analysis of raw data. Under conditions studied, parametric analysis of transformed data is more powerful than…

Discusses model-based simulation for training, explains an object-oriented approach, and describes RAPIDS, an authoring system for the production of interactive graphical models and instruction based on those models. Highlights include intelligent tutoring systems; transaction shells; tools for authoring models; and a course on retinal information…

Coefficient alpha was examined through computer simulation as an estimate of test reliability under violation of two assumptions. Coefficient alpha underestimated reliability under violation of the assumption of essential tau-equivalence of subtest scores and overestimated it under violation of the assumption of uncorrelated subtest error scores.…

Gives an overview of the development of multimedia, from the combination of film and computer graphics used during the 1960s to present day jet aircraft simulators. Definitions of multimedia, virtual reality, the use of compact disks to deliver digitally recorded information, and the economic need for the technology are discussed. (KRN)
