National and state science learning standards urge K-12 educators to offer authentic Science, Technology, Engineering, and Mathematics learning experiences. One way to fulfill this goal is to prepare preservice science teachers to integrate computer science skills, such as coding, into science education learning contexts that can benefit from it.…

Upon defining the terms modeling and simulation, it becomes apparent that there is a wide variety of different models, using different techniques, appropriate for different levels of representation for any one system to be modeled. Selecting an appropriate conceptual modeling technique from those available is an open question for the practitioner.…

For the fortieth time, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Jacksonville, Florida. The Proceedings of AECT's Convention are published in two volumes.…

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

A discipline in which scientists seek to simulate and synthesize lifelike behaviors within computers, chemical mixtures, and other media is discussed. A computer program with self-replicating digital "organisms" that evolve as they compete for computer time and memory is described. (KR)

Presents major considerations in modeling and simulation of variant forms of mental development, provides insight into simulation methods, describes the goals and essential features of two recent models representative of prominent behavioral modeling philosophies, and proposes underlying mechanisms for tow important aspects of development in…

This report describes the initial evaluation of a text compression algorithm against computer assisted instruction (CAI) material. A review of some concepts related to statistical text compression is followed by a detailed description of a practical text compression algorithm. A simulation of the algorithm was programed and used to obtain…

Computer simulation, a valuable tool for architects and urban designers, can produce unexpected pitfalls, costs, and results. (Author)

Described is a computer simulation designed to introduce students to some of the intricate relationships between the many factors involved in international economics. (MP)

Articles in this issue of "Global Journal of Computer Science and Technology" include: (1) Input Data Processing Techniques in Intrusion Detection Systems--Short Review (Suhair H. Amer and John A. Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

The America COMPETES Reauthorization Act of 2010 (Public Law 111-358) was put in place to invest in innovation through research and development, to improve the competitiveness of the United States, and for other purposes. The table of contents for this Act is as follows: (1) Sec. 1. Short title; table of contents; (2) Sec. 2. Definitions; and (3)…

Discusses a study which investigated whether a computer simulation model could suggest subroutines that were instructable and whether instruction on these subroutines could facilitate subjects' solutions to the problem task. (JM)

This research is concerned with the development and application of a computer-based simulation model of university baccalaureate degree nursing educational programs in the United States. (Author)

Establishes an argument that questions the validity of one test'' of goodness-of-fit (the extent to which a series of obtained measures agrees with a series of theoretical measures) for the simulated time path of a simple endogenous (internally developed) variable in a simultaneous, perhaps dynamic econometric model.
