Recoverability refers to the ease of recovering the underlying form--stored mental representations--given a surface form--actual, variable output signals s (e.g., [Daet^, Daet[superscript h] ] ? /Daet/ "that"). Recovery can be achieved from phonetic cues explicitly present in the acoustic signal or through prediction from the context.…

Despite their widespread use, there is little academic evidence on whether applicant selection instruments can improve teacher hiring. We examine the relationship between two screening instruments used by Spokane Public Schools to select classroom teachers, and three teacher outcomes: value added, absences, and attrition. We observe all applicants…

Syntactic (i.e., grammatical) complexity refers to the range and the degree of sophistication of the forms that appear in language production (Ortega, 2003). This concept has long been regarded as an important construct of language proficiency and has been actively investigated in the field of second language (L2) writing. Syntactic complexity is…

In this article, I provide answers to the questions posed by Will Shadish about the history and development of the Schmidt-Hunter methods of meta-analysis. In the 1970s, I headed a research program on personnel selection at the US Office of Personnel Management (OPM). After our research showed that validity studies have low statistical power, OPM…

The integrative approach of teaching Science, Technology, Engineering and Mathematics (STEM) has been advocated as a pedagogical means to advance education for the 21st century. However, there is a lack of validated instruments that are theoretically grounded to account for the various forms of knowledge that teachers need in order to effectively…

Wording effects associated with positively and negatively worded items have been found in many scales. Such effects may threaten construct validity and introduce systematic bias in the interpretation of results. A variety of models have been applied to address wording effects, such as the correlated uniqueness model and the correlated traits and…

The lack of an engaging pedagogy and the highly competitive atmosphere in introductory science courses tend to discourage students from pursuing science, technology, engineering, and mathematics (STEM) majors. Once in a STEM field, academic and social integration has been long thought to be important for students' persistence. Yet, it is rarely…

Teacher-student interpersonal relationships play an important role in education. The Questionnaire on Teacher Interaction (QTI) was designed to measure students' interpersonal perceptions of their teachers. There are two Chinese versions of the QTI for student use, and that inherited the weaknesses of the previous English versions, such as items…

Despite the critical role of emotions in multicultural teacher education, no attempt has been made to develop an instrument including affect as a dimension in measuring cultural competence for preservice teachers. To bridge this gap, the present three-study research used three distinct samples of 456 preservice teachers to develop and estimate the…

This study examined the role of sympathy, guilt, and moral reasoning in helping, cooperation, and sharing in a 6-year, three-wave longitudinal study involving 175 children (M[subscript age] 6.10, 9.18, and 12.18 years). Primary caregivers reported on children's helping and cooperation; sharing was assessed behaviorally. Child sympathy was assessed…

The purpose of this study was to investigate the joint and unique contributions of morphological awareness and vocabulary knowledge at five reading comprehension levels in adult basic education (ABE) students. We introduce the statistical technique of multiple quantile regression, which enabled us to assess the predictive utility of morphological…

A common methodological problem in the evaluation of the predictive validity of selection methods, e.g. in educational and employment selection, is that the correlation between predictor and criterion is biased. Thorndike's (1949) formulas are commonly used to correct for this biased correlation. An alternative approach is to view the selection…

In collaborative learning environments, students work together on assignments in virtual teams and depend on each other's contribution to achieve their learning objectives. The online learning environment, however, may not only facilitate but also hamper group communication, coordination, and collaboration. Group awareness widgets that visualize…

A few studies have indicated that dynamic measures of phonological awareness may contribute uniquely to the prediction of early reading development. However, standard control measures have been few and limited by floor effects, thus limiting their predictive value. The purpose of the present study was to examine the predictive value of a dynamic…

This study, with the aim of identifying the predictive power of the five-factor personality traits of music teacher candidates on individual instrument performance anxiety, was designed according to the relational screening model. The study population was students attending the Music Education branch of Fine Arts Education Departments in…
