These proceedings contain the papers of the 12th International Conference on Mobile Learning 2016, which was organized by the International Association for Development of the Information Society, in Vilamoura, Algarve, Portugal, April 9-11, 2016. The Mobile Learning 2016 Conference seeks to provide a forum for the presentation and discussion of…

The "Technology Outlook Australian Tertiary Education 2013-2018: An NMC Horizon Project Regional Analysis" reflects a collaborative research effort between the New Media Consortium (NMC) and Open Universities Australia to help inform Australian educational leaders about significant developments in technologies supporting teaching,…

There has been increasing attention to the fine structure of abilities underlying task performance (E. H. Haertel and D. E. Wiley). One of the most useful approaches for this is by use of graphical models to represent relationships among abilities and test items. Building a large graphical model is always an issue. Restrictions upon experiments…

The jackknife and bootstrap methods are becoming more popular in research. Although the two approaches have similar goals and employ similar strategies, information is lacking with regard to the comparability of their results. This study systematically investigated the issue for a canonical correlation analysis, using data from four random samples…

A modification of the SIBTEST procedure to assess differential item functioning (DIF) for two-dimensional test data (i.e., data for tests where two intended abilities are tapped by test items) is described. A small simulation study is carried out to assess the performance of the modified SIBTEST to detect DIF in such two-dimensional data. The…

The Grube Method of Instruction is a teaching and learning system for the acquisition and reinforcement of essential learned skills necessary for school success. The system consists of an illustrated book of useful information, a deck of standard playing cards, and an educationally designed gameboard. It is appropriate for students aged three…

This paper describes how to create a deck of 56 playing cards using historical or educational facts in place of the numbers on the playing cards. Card data also deal with various games and activities to address interest and learning styles. (EH)

Robustness and power of parametric, semi-parametric, and nonparametric tests of between-group discordance were compared in this simulation study. The empirical Type I error rates and power of nine tests were compared. When data were sampled from the any differences especially favor young women in single-sex Catholic secondary schools, and whether…

This discussion of new methods for calibrating item response theory (IRT) models looks into new optimization procedures, such as the Genetic Algorithm (GA) to improve on the use of the Newton-Raphson procedure. The advantages of using a global optimization procedure like GA is that this kind of procedure is not easily affected by local optima and…

When multiple linear regression is used to develop a prediction model, sample size must be large enough to ensure stable coefficients. If the derivation sample size is inadequate, the model may not predict well for future subjects. The precision efficacy analysis for regression (PEAR) method uses a cross- validity approach to select sample sizes…

Person-fit research in the context of paper-and-pencil tests is reviewed, and some specific problems regarding person fit in the context of computerized adaptive testing (CAT) are discussed. Some new methods are proposed to investigate person fit in a CAT environment. These statistics are based on Statistical Process Control (SPC) theory. A…

Cross-validation, an economical method for assessing whether sample results will generalize, is discussed in this paper. Cross-validation is an invariance technique that uses two subsets of the data sample to derive discriminant function coefficients. The two sets of coefficients are then used with each data subset to derive discriminant function…

A simulation study was conducted to identify the best hot-deck variation to impute missing values. The three variations included in the study were the hot-deck random, the hot-deck sequential, and the hot-deck distance. The properties of these methods were investigated under three levels of the proportion of incomplete records and four levels…

In response to requests for information relating to the emotional maltreatment of children, the Region 6 Child Abuse and Neglect Resource Center produced a videotape depicting a fictional courtroom hearing conducted to determine whether or not a child should be temporarily removed from his parents' custody on the grounds of emotional maltreatment.…
