The need for a new measure of social-emotional wellbeing for children 6--12 years emerged in our collaboration with schools and community agencies in a disadvantaged region of Brisbane, Australia. Our search for an age-appropriate medium led us to develop "Clowning Around", a computer game generating data which was assessed for validity…

There is little empirical data on the extent of home numeracy practice using technology, though previous research shows that home numeracy activities are linked with children's mathematics abilities. This study describes the process of constructing an inventory of digital home numeracy practice (DHNP-i). Parents (n = 126) of elementary children…

Background: In education, Information and Communication Technology (ICT) has gone from being a convenient option to a permanent necessity. For students and people with functional diversity, it is of seminal importance. It is therefore worth learning how professionals perceive digital tools and apps for people and students with functional diversity…

Adoption of new instructional standards in science demands high-quality information about classroom practice. Teacher portfolios can be used to assess instructional practice and support teacher self-reflection anchored in authentic evidence from classrooms. This study investigated a new type of electronic portfolio tool that allows efficient…

A computerized system was developed for generating narrative interpretations of scores from a battery of personnel screening tests. Showed the computerized reports to be more accurate and thorough, as readable, and somewhat less coherent than interpretations generated by the typical human expert. (Author/ABB)

Examines the validity of a Minnesota Multiphasic Personality Inventory code type interpretive program. Results showed the system was highly rated by three independent experienced clinicians. The program can be used in validating other automated test interpretation systems. Feedback by expert judges can be used to improve such systems. (Author/JAC)

Learning hierarchies are networks of prerequisite relationships of instructional objectives. Seven measures of the validity of learning hierarchies were compared for their ability to identify correctly- and incorrectly-ordered hierarchies. A computer simulation model was used to generate stochastic data of known underlying structure. Analysis of…

In latent trait theory the latent space, or space of the hypothetical construct, is usually represented by some unidimensional or multi-dimensional continuum of real numbers. Like the latent space, the item response can either be treated as a discrete variable or as a continuous variable. Latent trait theory relates the item response to the latent…

The nonparametric approach to test theory discussed here has its roots in the early work of Guttman, Lazarsfeld, and Meredith; and more recently in the work of Cliff and in Tatsuoka and Tatsuoka. Mokken's extensive treatment of this subject concentrated on defining, constructing, and testing unidimensional scales, based on responses to dichotomous…

This paper reviews the basic elements of the EM approach to estimating item parameters and illustrates its use with one simulated and one real data set. In order to illustrate the use of the BILOG computer program, runs for 1-, 2-, and 3-parameter models are presented for the two sets of data. First is a set of responses from 1,000 persons to five…

A conventional vocabulary test and two forms of a stradaptive vocabulary test were administered by a time-shared computer system to undergraduate college students. The two stradaptive tests differed in that one counted question mark responses (i.e., omitted items) as incorrect and the other ignored items responded to with question marks.…

It may be possible, using assessments of motor and perceptual skills which are largely independent of ethnic and educational background, to admit to the military individuals who would be rejected on the basis of their paper-and-pencil test scores, but who through their performance on non-verbal measures, can be identified as highly likely to…
