This study presents and evaluates a method of standardization that may be used by test practitioners to standardize classical item statistics when sample sizes are small. The effectiveness of this standardization approach was compared through simulation with the one-parameter logistic (1PL) and three parameter logistic (3PL) models based on the…

A simulation study was conducted to examine the effect of large ability differences using two differential item functioning (DIF) detection procedures, SIBTEST and TESTGRAF. DIF items are hard to identify when group ability differences are large (A. Gotzmann, C. Vandenberghe, and M. Gierl, 2000; R. Hambleton and H. Rogers, 1989). This problem was…

This study focused on the issue of measurement reliability and its attenuation on correlation between two composites and two seemingly different approaches for correcting the attenuation. As expected, Monte Carlo simulation results show that correlation coefficients uncorrected for measurement error are systematically biased downward. For the data…

The generalized graded unfolding model (J. Roberts, J. Donoghue, and J. Laughlin, 1998, 1999) is an item response theory model designed to unfold polytomous responses. The model is based on a proximity relation that postulates higher levels of expected agreement with a given statement to the extent that a respondent is located close to the…

A simulation study compared three methods of estimating parameters within structural equation models (SEM) with polytomous variables. These methods appear in three SEM computer software packages: (1) LISREL (Joreskog and Sorbom, 1996) with PRELIS (Joreskog and Sorbom); (2) EQS (Bentler, 1995); and (3) the new Mplus (Muthen and Muthen, 1998). The…

A method of simulation to tie check writing, making deposits, finding outstanding checks, receiving bank statements, and bank reconciliation into a process is presented as a way to convey to students a feeling of a procedure completed. A step-by-step teaching procedure and examples of bank statements are included. (AG)

As implemented by Colgate University, the Inter-Nation Simulation'' attempts to create a functioning microcosm of teams or nations which interact politically, economically, and sociologically. (JA)

In this article, the Double I (Individualized Instruction) Game is described, including its objectives, rules of play, participants, and materials. The purpose of the game is to permit parents and teachers to consider their feelings about the implementation of individualized instruction. (HMD)

Describes two experiments which a) investigated the effect of communication on cooperative choice during play of a Prisoner's Dilemma game under conditions of real reward and b) examined the effect of communication on a situation that simulated the type of environment that may result in a collusive crime. (JA)

Provides a fast motivating method for providing people with practice in making discriminations among simulation games, nonsimulation games, nongame simulations, instructional games, noninstructional games, instructional simulation games, etc. (Author)

A voluntary college orientation weekend which involved roleplaying activities through which the participants learned more about themselves, their companions, and their priorities is described. (JC)

A discussion of possible uses of computer simulation in high schools and colleges when direct experimental experience is not available to the student. Sample runs of three simulation programs are also presented. (AK)
