The Use of Loglinear Models for Assessing Differential Item Functioning Across Manifest and Latent Examinee Groups

Loglinear latent class models are used to detect differential item functioning (DIF). These models are formulated in such a manner that the attribute to be assessed may be continuous, as in a Rasch model, or categorical, as in Latent Class Mastery models. Further, an item may exhibit DIF with respect to a manifest grouping variable, a latent grouping variable, or both. Likelihood-ratio tests for assessing the presence of various types of DIF are described, and these methods are illustrated through the analysis of a "real world" data set.     

Three Cases of Hashtags Used as Learning and Professional Development Environments

Hashtags offer exciting opportunities for professional development, teaching, and learning. However, their use reflects users’ needs and desires. To illustrate and problematize the ways hashtags are used in professional development settings, this study reports on users’ participation patterns, users’ roles, and content contributed to three unique hashtags. This mixed methods research employs data mining techniques to retrieve data. Using a collective case study methodology, the study compares and contrasts the use of three hashtags and offers insights into the use of hashtags as emerging learning and professional development environments. Results show that hashtags exhibit similarities, such as unequal user participation. Findings also reveal differences between hashtags. For instance some hashtags are used on an ongoing basis while others have well-defined start and end dates. Ultimately, these results question deterministic thinking with respect to emerging technologies and novel professional development environments.     

Socialization and Family Correlates of Mental Health Outcomes among Hispanic and Anglo American Children: Consideration of Cross-Ethnic Scalar Equivalence

Recently there has been concern over the need for developmental research within ethnic minority populations and interest in socialization and family variables within, and variability across, ethnic groups. This study reports analyses designed to: compare several socialization, family, and mental health variables among Hispanic and Anglo American 8–14-year-old children and mothers; examine the regression equations predicting mental health indicators with the socialization and family variables; and evaluate the cross-ethnic scalar equivalence of these socialization and family measures. The findings indicate that there are ethnic differences in several socialization and family variables; several of the socialization and family variables are related to the mental health variables, and these relations are very similar across ethnic groups; and the socialization and family measures appear to have sufficient cross-ethnic scalar equivalence for English-speaking, largely Mexican American Hispanic samples. Further, these findings suggest some caution regarding the use of the Child Depression Inventory in Hispanic samples.     

>OFSTED: inspecting schools and improvement through inspection

Approximately one‐third of all maintained secondary schools in England, and a smaller tranche of nursery, primary and special schools, were inspected under the arrangements set out in Section 9 of the 1992 Education (Schools) Act by the end of 1994. This article reviews some aspects of quality assurance in the national inspection system in England. It looks in particular at the improvement of inspection and at improvement through inspection. Continuous improvement of the inspection system reflects feedback from key stakeholders, as well as work by OFSTED to incorporate new developments. Improvement through inspection, broadly defined, has to cover both what occurs at the individual school level and in the system at large as a result of inspection. We argue that an effective inspection system can provide a powerful incentive for, as well as directly contributing to, school improvement and development     

Characteristics of children referred for evaluation of school difficulties who have adequate academic achievement scores

Forty children (7 to 11 years old) referred for evaluation of learning problems, who had scores within the normal range on standardized measures of academic achievement, were compared to 81 similarly referred children who had scored low (< 90) on at least one measure of academic achievement. We tested the hypothesis that children with normal achievement scores who are referred for evaluation of learning problems show neuropsychological profiles comparable to those of children with low achievement. Referral problems, school history, IQ, academic achievement, and neuropsychological function were evaluated. Referred children with normal achievement scores came from more advantaged backgrounds and had less intensive academic interventions, higher IQs, and better decoding skills. Nonetheless, the two groups showed similar neuropsychological profiles. Vulnerability to complexity and decreased automaticity were prominent. Normal-range achievement test scores among children referred for evaluation should not be regarded as indicating absence of neurodevelopmental vulnerability.     

Adult education as corporate social responsibility in Canadian mining companies: performing the good citizen for greater self-regulation

This paper examines the underexplored role adult education activities play as part of Canadian Mining Companies’ corporate social responsibility (CSR) efforts. We argue that adult education as CSR provides companies with a symbolic capital they can draw upon to detract from government oversight, increase profits, and continue operations. Taking place within a structure of increased corporate power and lacking any regulatory framework, CSR is often divorced from the overall ethos of a company. Moreover, the impact of adult educational initiatives on individuals and communities remains largely unknown, highlighting the need for further research.     

A course projection and staffing plan used to facilitate a curriculum change

The curriculum change for which these projections were made included eliminating traditional distribution requirements in favor of interdisciplinary programs and increased student electives. The plan allowed study of the staffing needs and anticipated effects upon departmental offerings. The projections provided estimates of the number of students who would take each type of course and indicated that the new curriculum could be staffed by eliminating previously required introductory courses. Updated each year, the plan served as a guide for departmental offerings and for the hiring of new faculty. The projection methods employed would be helpful for schools anticipating curricular changes or as a general guide in planning faculty allocations from year to year.The planning, initial costs, and evaluation of the curriculum were supported in part by grants from the National Endowment for the Humanities, the George Gund Foundation, and the U.S. Office of Education. Reprints and additional information about the curriculum and these projections can be obtained from the Office of Records and Research, Hiram College, Hiram, Ohio 44234. The authors wish to acknowledge the encouragement and assistance of Hiram President Elmer Jagow, former Dean Wendell Johnson, and current Dean Robert MacDowell. The cooperation of the Hiram faculty and students is also gratefully acknowledged.     

Instrumentation (GSR) and Its Effects On Counselor Responses

This study investigated the feasibility of using client GSR responses to increase counselor sensitivity to clients during the counseling interview. Six counselors counseled 22 clients under experimental conditions in which they observed clients' GSR responses and 22 control clients whose GSR responses were not visible to them. Clients were matched on the variables of age, sex, general diagnosis, counseling session number, and type and effect of medication, if any. Counselor responses, classified according to a modified Porter scale, were compared between experimental and control conditions. A significant difference (p<.01) between experimental conditions was observed with counselors appearing to use more probing and fewer understanding statements while viewing their clients' GSR responses.     

The incidence of severe physical child abuse in Wales

OBJECTIVES: The purposes of this study were: (1) to ascertain the incidence and nature of severe physical child abuse in Wales; (2) to ascertain the incidence of all physical abuse in babies under 1 year of age; and (3) to determine whether child protection registers (CPR) accurately reflect the numbers of children who are physically abused. METHODS: This is a population-based incidence study based in Wales, UK, for 2 years from April 1996 through March 1998. Children studied were under the age of 14 with severe physical abuse consistent with the criminal law level of Grievous Bodily Harm. This included seven categories of injury (death; head injury including subdural hemorrhage; internal abdominal injury; physical injury in Munchausen Syndrome by Proxy including suffocation; fracture; burn or scald; adult bite). Cases were ascertained by a pediatrician surveillance reporting system (WPSU). A criterion for inclusion was multidisciplinary agreement that physical abuse had occurred (at case conference, strategy meeting, or Part 8 Review). The incidence of all babies under 1 year of age with physical abuse was also studied. Ascertainment of babies under the age of 1 year was undertaken from CPR as well as the WPSU. RESULTS: Severe abuse is six times more common in babies [54/100,000/year (95% CI +/- 17.2)] than in children from 1 year to 4 years of age [9.2/100,000 (95% CI +/- 3.6)]. It is 120 times more common than in 5- to 13-year-olds [0.47/100,000 (95% CI +/- 0.47)]. This is mainly because two types of serious abuse (brain injury including subdural hemorrhage and fractures) are more common in babies under the age of 1 year than older children. Using data from two sources (the WPSU and CPRs), the incidence of physical abuse in babies is 114/100,000 (CI 114 +/- 11.8) per year. This equates to 1 baby in 880 being abused in the first year of life. The largely rural Health Authority area in Wales had incidence figures for abuse in babies that were 50% of the three other predominantly urban Health Authority areas. Boys throughout the series were more at risk of being severely abused than girls (p < .025). Only 29% of the babies under 1 year of age on the CPR had actually been injured. Thirty percent of abused babies under the age of 1 year and 73% of severely abused children over the age of 1 year had caused previous concern to health professionals regarding abuse or neglect. Conclusions: Physical abuse is a significant problem in babies under the age of 1 year. Very young babies (under 6 months old) have the highest risk of suffering damage or death as a result of physical abuse. Severe abuse, in particular subdural hematoma and fracture, is much more common in babies than in older children. There is evidence of failure of secondary prevention of child abuse by health professionals, with a greater need to act on concerns regarding abuse and neglect. Interagency child protection work in partnership with parents should focus more on protecting babies under age 1 year from further abuse than on maintenance of the infant within an abusive home. The CPR is not intended as an accurate measure of children suffering abuse. It is a record of children requiring a child protection plan and must not be used as a measure of numbers of abused children.     

The Influence of Toy Design Activities on Middle School Students’ Understanding of the Engineering Design Processes

The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students’ self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students’ self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students’ understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students’ engineering design self-efficacy and qualitative analyses to identify students’ understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students’ self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students’ understanding of engineering design processes. This research provides insights into the key elements of middle school students’ engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops.
