A System at Risk: College Outreach Programs and the Educational Neglect of Underachieving Latino High School Students

This literature review examines the ways in which college and university outreach programs impact Latino (and other minorities) high school students. This article demonstrates that the outreach programs outlined do aid in closing the gap of college enrollment for Latinos. However, a review of three representative programs—AVID, the University of California's Early Academic Outreach Program, and Upward Bound—reveals that the Latino students who exhibit the most need are summarily excluded from participating in the programs, thus leaving them on the margins of the educational system. One of the conclusions of this study is that the problem lies with the political nature of the programs, which causes them to have stringent eligibility criteria.     

Measuring Educators' Attitudes and Beliefs About Evaluation: Construct Validity and Reliability of the Teacher Evaluation Experience Scale

This study presents the reliability and validity of the Teacher Evaluation Experience Scale–Teacher Form (TEES-T), a multidimensional measure of educators' attitudes and beliefs about teacher evaluation. Confirmatory factor analyses of data from 583 teachers were conducted on the TEES-T hypothesized five-factor model, as well as on alternative models. The five- and four-factor model yielded acceptable fit to the data. Information-theory-based indices of relative fit (i.e., AIC₀, BCC₀, and BIC₀) indicated that the TEES-T four-factor model yielded superior fit to either the five-factor or one-factor models. The TEES-T evidenced good internal consistency, freedom from item bias, and convergent validity with the Collective Efficacy Scale. Implications are discussed.     

A NATIONAL INVESTIGATION OF SCHOOL PSYCHOLOGY TRAINERS’ ATTITUDES AND BELIEFS ABOUT EVIDENCE‐BASED PRACTICES

The present investigation examined 460 school psychology trainers’ attitudes and beliefs about the conditions for the education and training of evidence‐based practices (i.e., assessments and interventions) in training programs in the United States and Canada using an online survey. Trainer attitudes and beliefs about education and training in evidence‐based practices were measured using a 24‐item five‐point Likert scale. Overall, trainers had positive views of evidence‐based practices, as well as program and organizational support for such training. However, trainers rated the education and training of evidence‐based assessments more favorably than evidence‐based interventions. In general, trainer characteristics nor program accreditation status, model, or type of degree offered were found to influence trainers’ perceptions about evidence‐based practices. However, trainers with prior experience teaching evidence‐based intervention courses were found to have more supportive views of evidence‐based assessments and interventions than those without such experience. Implications for future training and school practice are discussed.     

Alternative Routes into the Teaching Profession

This article examines the ways in which the development of alternative initial teacher education programs in England and Canada over the last two decades serve to challenge some of the taken-for-granted assumptions underlying established models of initial teacher education in both jurisdictions, and also to broaden the pool of people who have access to the profession. The article offers a brief, initial account of the development of a standard model of initial teacher education in both countries that is characterized as being: university governed and university based; primarily full-time; incorporating a standard curriculum, with admission requirements that generally reflect the traditional academic expectations of the university; and which is funded jointly by the student and the state. Against this standard model the article examines the development of alternative or flexible models in both Canada and England. Three programs are described in some detail – The Brandon University Northern Teacher Education Program, The University of Manitoba’s Weekend College Teacher Education Program, and The University of Nottingham’s Flexible, Modularized Post-Graduate Certificate in Education Program – and each is examined in terms of the ways in which it challenges the assumptions embedded in traditional teacher education programs. At a time when attracting talented and committed teachers constitutes an important issue facing public education systems in both countries, the ability to construct high quality initial teacher education programs that can provide access to the profession to as wide a cross-section of the population as possible will be an important contribution to meeting this challenge.     

Mobile agents

A software agent is an intelligent program that acts as a user’s personal assistant. Software agents endowed with the property of mobility are called mobile agents. Mobile agents perform a user’s task by migrating and executing on several hosts connected to the network.
