The present research examined and compared Australian and Chinese teachers' personal efficacy in instruction, discipline, guidance and beliefs about external influences. Two staged studies were conducted with the participation of 316 Australian teachers (108, 208 in first and second stages, respectively) and 411 Hong Kong Chinese teachers (138,…

The purpose of this study was to examine the utility of the Differential Ability Scales (DAS) in distinguishing preschoolers with specific language impairment (SLI) and specific subtypes of language delays. Three hundred forty-eight language-impaired preschoolers' response patterns across DAS General Conceptual Ability (GCA), Ability cluster, and…

E-learning is expected to support organizations and individuals so they can become more adaptable and competitive. However, in order for organizations to realize the full potential of this technology, they should create and sustain the right context to foster learning in articulation with business objectives. This requires active participation and…

Background: Given the importance of parenting for the child's early socio-emotional development, parenting perceptions and behaviours, and their correlates, should be assessed as early as possible in the child's life. The goals of the present study were 1) to confirm, in two parallel population-based samples, including a large sample of twins, the…

The purpose of this article was to report factor structures, reliability, and validity of the Significant Other Academic Support Scale from two different Latino samples of Mexican and Central American origin youth. Self-report data were collected from 394 Mexican and 220 Central American youth from immigrant families living in Los Angeles.…

The study set out to assess the needs of Nigerian science teachers, which the teachers believe are militating against their desired productivity. It seeks to find out the special needs and wants of science teachers in trying to discharge their duties well, and to find out the underlying relationship among these specials needs and wants. Six…

Study strategies are the activities that an individual uses to facilitate learning. Although no consistent findings exist to show the factors that comprise the study-strategy concept, a three-factor conceptualization (cognitive, affective, and behavioral) is often suggested. These factors were studied with 128 undergraduates of high and low…

The issue of what exactly is measured by different types of reading items has been a matter of interest in the field of reading research for many years. Language teaching and testing specialists have raised the question of whether a reading test for foreign students wishing to enter a university in the United States should include questions…

A validation study was conducted on the Child Sex Abuse Attitude Scale (CSAAS) using confirmatory factor analysis (CFA) to examine the factor structure of three comparative CFA models. Multitrait multimethod analysis was also used to examine the convergent and discriminant validity of the CSAAS. The instrument was developed based on the theory of…

A multidimensional item response theory (IRT) model for polytomously scored items, based on the graded response model and using the normal ogive, is developed; and an EM algorithm that may be used to estimate the parameters of the model is also discussed. The model is illustrated through a simulation study in which the polytomous item responses of…

This study used multiple methods to assess basic community needs and attributes of community atmosphere (cohesion, religious involvement, and recreational activities) in two psychometric studies. Part 1 revised self-report community assessment measures, developed multi-item scales for each construct, and tested reliabilities and factor structures…

The structure of a concept generally labeled "teacher efficacy" is examined. A sample of 342 prospective and experienced teachers was administered an efficacy questionnaire adapted from the research of S. Gibson and M. H. Dembo (1984). Factor analytic procedures with varimax rotation were used to generate a 2-factor solution that accounted for 32…

Negative item bias is produced by the inability of preadolescent children to respond appropriately to negatively worded items on rating scales, and is hypothesized to be a cognitive-developmental phenomenon. The effect is examined with responses to the Self Description-Questionnaire (SDQ), a multifactor self-concept instrument. In study 1,…

The construct validity of biographical items in the Individual Achievement Record (IAR) was assessed in an attempt to develop a confirmatory factor model. This first phase of a two-phase study focused on the IAR's use as a predictor of job performance. The IAR is an empirically keyed biodata inventory containing 112 multiple-choice items. Item…

Construct validity of a prototype baccalaureate generic problem solving skills test was explored through a structural analysis. The assessment method used three real-life problem situations crossed by six generic skills, namely Decision-Making, Communication, Analysis, Synthesis, Valuing and Execution. There were six written responses for each…
