This study applied the maximum expected information (MEI) and the maximum posterior-weighted information (MPI) approaches of computer adaptive testing item selection to the case of a test using polytomous items following the partial credit model. The MEI and MPI approaches are described. A simulation study compared the efficiency of ability…

This article discusses 5 approaches that secondary researchers might use to obtain robust estimates in structural equation modeling analyses when using data that come from large survey programs. These survey programs usually collect data using complex sampling designs and estimates obtained from conventional analyses that ignore the dependencies…

Critical in virtually all educational arenas, gaming and simulation techniques and distance learning are major areas of interest in today's U.S. Army training. The U.S. Army Armor School at Ft. Knox, KY contracted with the University of Louisville and Northrop Grumman Mission Systems in 2003 to develop online training for Army Captains. They…

Many changes are taking place in our country. Technology continues to impact on the workplace, demographics are changing the face of our neighborhoods, communities, and work environments. Globalization is placing greater demands on the economy and on workers. Educators and employers must face the challenge of how to prepare learners for new roles…

A subcategory of computer-assisted instruction (CAI), games have additional attributes such as motivation, reward, interactivity, score, and challenge. This study used a quasi-experimental design to determine if previous findings generalize to non simulation-based game designs. Researchers observed significant improvement in the overall population…

In this study, the research problem was: "Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?" For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control…

This study explores the social impact of ADHD, with and without opposition-defiant behaviour [ADHD+ODD (n= 22) and ADHD-only (n= 18)], in 9- to 12- year old girls compared to girls without ADHD (n= 40). Girls played a computer game involving simulated players, and mothers and teachers completed rating scales. In general, mothers and teachers saw…

Adapting training methods to specific teacher traits to best facilitate the training effects for preservice teachers is an important, yet neglected, topic in aptitude-treatment interaction research. This study investigated interactions between four personal traits (CT-dispositions, thinking styles, CT-skills, and intrapersonal intelligence) and…

This work proposes an approach to remote learning of robotic cells based on internet and simulation tools. The proposed approach, which integrates remote-learning and tele-operation into a generic scheme, is designed to enable students and developers to set-up and manipulate a robotic cell remotely. Its implementation is based on a dedicated…

The objective of this article is to study the network and virtual reality technologies for developing a virtual dinosaur museum, which provides a Web-learning environment for students of all ages and the general public to know more about dinosaurs. We first investigate the method for building the 3D dynamic models of dinosaurs, and then describe…

This article presents an interview with Jeremy Koester, an eighth grade math teacher and football coach at Alamo Heights Junior School in San Antonio, Texas. In this interview, Koester describes his use of technology in his classes and describes his dream of advancing Second Life (SL) as a distance education environment. SL is a "3-D virtual…

For the thirty-seventh year, the Research and Theory Division and the Division of Instructional Design of the Association for Educational Communications and Technology (AECT) sponsored the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Jacksonville, Florida. This year's Proceedings…

The objective of this article is to investigate the computer animation and virtual reality technologies for developing a virtual marine museum. The museum consists of three exhibition areas. The first area displays fishes in freshwater, including creeks, rivers, and dams in Taiwan. The second area exhibits marine ecology and creatures of different…

This article describes a university-sponsored experiential-based simulation, the NANO SCENARIO, to increase the public's awareness and affect attitudes on the societal implications of nanoscience and nanotechnology by bringing together diverse stakeholders' perspectives in a participatory learning environment. Nanotechnology has the potential for…
