An effective mathematics and science curriculum option for secondary gifted education

Project Ga‐GEMS (Georgia's Project for Gifted Education in Math and Science) viewed the effect that placement in an integrated, hands‐on mathematics and science curriculum had on the achievement of academically talented high school students. For a two‐year period of time, students gifted in the areas of mathematics and science participated in a curriculum which incorporated higher‐level thinking skills and more real life laboratory experiences into mutually reinforcing mathematics and science lessons. After the conclusion of the two‐year program, Ga‐GEMS participants and a control group were given the mathematics and science sections of the ACT as they exited the tenth grade. The Ga‐GEMS students scored significantly higher on the Science Math Total, Pre‐Algebra/Elementary Algebra, Intermediate Algebra/Coordinate Geometry and Plane Geometry/Trigonometry sections of the ACT. To determine if the Ga‐GEMS students retained their higher scores throughout high school the SAT scores of both groups were compared as the students exited high school. Significant differences in the areas of total score and mathematics were noted. This study lends support for the use of a differentiated curriculum for educating gifted students in science and mathematics.     

Implementing the Ecosystemic Approach to Changing Chronic Problem Behaviour in Schools

The present paper discusses a study of the ecosystemic approach to changing chronic problem behaviour in schools undertaken with a group of 33 primary and two secondary teachers. The impact of the ecosystemic techniques and the main theoretical issues are discussed. Three case examples are presented and conclusions are drawn on the potential of this new approach.     

Centering Marginalized Voices

Abstract

“Centering Marginalized Voices” is the second of nine Christian life rhythms explored in the upcoming book tentatively titled Staying Awake: The Gospel for Changemakers (Chalice Press). Author Rev. Tyler Sit explains how his multiethnic, Millennial church plant in South Minneapolis (New City Church, https://GrowNewCity.church), follows Jesus in opposing racism and constructing a diverse community. Staying Awake is written to be lay-accessible and models how pastors can communicate core theological themes in the Gospel.     

Neural information retrieval: at the end of the early years

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.     

The effect of CD-ROM MEDLINE on online end-user and mediated searching: a follow-up study

Indiana University School of Medicine Library (IUSML) has traditionally been a high volume searching institution. The dramatic effect of CD-ROM on online end-user searching and the negligible effect on mediated searching was reported in an earlier study. This follow-up study reveals that the proportion of mediated searching has been drastically reduced from 94% in 1986/87 to 39% as of November 1989. Mediated searches are declining in absolute numbers as well. End-user searching, by contrast, has increased by 54% percent over the previous year. A related trend is the increased use of CD-ROM by the librarian as an alternative to mediated online searching. These trends are expected to continue as IUSML expands its CD-ROM operation to include other databases. As mediated searching declines, the librarian's role will increasingly include end-user training.     

MEASURING KINDNESS AT SCHOOL: PSYCHOMETRIC PROPERTIES OF A SCHOOL KINDNESS SCALE FOR CHILDREN AND ADOLESCENTS

In this study, we sought to create and validate a brief measure to assess students’ perceptions of kindness in school. Participants included 1,753 students in Grades 4 to 8 attending public schools in a large school district in southern British Columbia. The School Kindness Scale (SKS) demonstrated a unidimensional factor structure and adequate internal consistency. The pattern of associations of the SKS to a corpus of theoretically relevant constructs obtained via student self‐reports (classroom supportiveness, optimism, happiness, prosocial and social goals, satisfaction with life, and academic self‐efficacy) provided evidence for convergent and discriminant validity. Furthermore, the SKS was significantly and positively associated with teacher reports on students’ empathy, social skills, and peer acceptance. Analyses by gender and grade indicated that girls perceived significantly higher levels of kindness in school than did boys, and that students’ perceptions of kindness in school decreased from fourth to eighth grade, with fourth‐grade students reporting the highest levels of kindness in school and eighth‐grade students reporting the lowest levels. The theoretical importance of investigating students’ perceptions of kindness in the school context and the practical implications of this research for informing educational efforts to promote social and emotional competencies in school communities are discussed.     

Why everything has changed: the recent revolution in cultural economics

The internet, the iPod, the cell phone, Kindle, blogs, computer games, and virtual realities mean that cultural economics has changed an enormous amount in just the last five years. I explain and analyze some of the implications of these changes. Plenary address at the 2008 ACEI meetings, Boston, Massachusetts. I wish to thank meeting participants for useful comments and questions and thank Jennifer Rogers for her help in transcribing the talk.
