Electronic Roads in Historical Documents: A Student Oriented Approach

The new educational approaches, as far as teaching of history in secondary education is concerned, are characterized by a shift away from sterile memorization and towards a critical approach of historical facts and phenomena; the aim is to contribute to both the development of students' historical concept and conscience and the promotion of critical thought. These teaching goals are pursued by promoting initiative of the students through self study assignments in the form of projects; students can be greatly supported in such tasks by computer-based applications, which can offer access to vast amounts of historical texts and data to be used next to the main scholar textbook and be analyzed by students. Still, existing applications seem to be quite inadequate for this purpose, as they require that the student be already informed on a matter, before the initiation of a quest for data. In this paper, we describe an intelligent information system that is designed to facilitate browsing of educational material and historical sources, thus allowing students to efficiently retrieve information on topics that are not yet known to them and expand in this way their historical knowledge. This can help in fulfilling the aforementioned teaching goals. Our system relies on the notion of the Electronic Road.     

Reward magnitude and shock variables (continuity and intensity) in shuttlebox-avoidance learning

In Experiment I, eight groups of rats (n = 20) were given shuttlebox-avoidance training. Two levels of shock (.3 and 1.6 mA) were combined factorially with two levels of reward (large and small) under both continuous and discontinuous (.75 sec on and 2.00 sec off) shock. Visual situational cues were absent after a shuttle response for the large-reward condition and present for the small-reward condition. Superior performance was obtained with weak rather than strong shock under both reward conditions and with large rather than small reward only under the weak-shock condition. Continuity of shock had no differential effect on performance. Experiment II allowed the conclusion that the reward effect was attributable to a reinforcement mechanism. The data were taken as support for the effective reinforcement theory, which emphasizes the importance in avoidance learning of fear conditioned to situational cues.     

Randomized trial of a statewide home visiting program: impact in preventing child abuse and neglect

OBJECTIVES: To assess the impact of home visiting in preventing child abuse and neglect in the first 3 years of life in families identified as at-risk of child abuse through population-based screening at the child's birth. METHODS: This experimental study focused on Hawaii Healthy Start Program (HSP) sites operated by three community-based agencies. From 11/94 to 12/95, 643 families were enrolled and randomly assigned to intervention and control groups. Child abuse and neglect were measured by observed and self-reported parenting behaviors, all hospitalizations for trauma and for conditions where hospitalization might have been avoided with adequate preventive care, maternal relinquishment of her role as primary caregiver, and substantiated CPS reports. Data were collected through annual maternal interviews (88% follow-up each year of all families with baseline interviews); observation of the home environment; and review of CPS, HSP, and pediatric medical records. RESULTS: HSP records rarely noted home visitor concern about possible abuse. The HSP and control groups were similar on most measures of maltreatment. HSP group mothers were less likely to use common corporal/verbal punishment (AOR=.59, p=.01) but this was attributable to one agency's reduction in threatening to spank the child. HSP group mothers reported less neglectful behavior (AOR=.72, .02), related to a trend toward decreased maternal preoccupation with problems and to improved access to medical care for intervention families at one agency. CONCLUSIONS: The program did not prevent child abuse or promote use of nonviolent discipline; it had a modest impact in preventing neglect. Possible targets for improved effectiveness include the program's implementation system and model.     

The relationship between gender, depression, and self-esteem in children who have witnessed domestic violence.

OBJECTIVE: To investigate whether there are measurable gender differences in self-esteem and depression in elementary school-age children who have witnessed domestic violence. METHOD: Forty-five elementary school-age children who were identified as having witnessed domestic violence, and their teachers were surveyed for self-esteem, depression, and classroom behaviors. The results were compared between males and females using linear regression modeling. RESULTS: No significant gender differences were found for self-esteem and depression. An interaction between gender and post-traumatic stress was found to play a significant role in the interpretation of the results. CONCLUSIONS: Results indicated that higher levels of symptoms indicative of post-traumatic stress were associated with greater numbers of depressive symptoms and lower self-esteem for boys who had witnessed domestic violence. The results appeared similar to previous work with children and their emotional reactions to divorce.     

Orchestrating Complex Educational Change: Local Reorganisation of Schools in England

This paper considers how complex educationalchange may be managed through the `metatask' oforchestration, narrowly distributed amongsenior formal leaders within and betweendifferent administrative levels of large publiceducation systems. Orchestration impliessteering the change process by organising andmaintaining oversight of an intricate array ofcoordinated tasks. It is the over-arching`complex change management theme' of ahierarchically ordered typology derivedinductively from a national study ofdistrict-wide initiatives to close or mergeschools so as to reduce spare student capacityand improve the quality of educationalprovision. The paper explores patterns revealedby this research relating to orchestration. Theresearch design and methods are outlined. Therelationship is clarified between the conceptsof orchestration, leadership and management. Ananalytical model is built-up for analysingcomplex educational change along threedimensions: change management themes, headed byorchestration; characteristics of thecomplexity of the change with managementimplications; and stages of the change process.The constituents of each dimension in turn aredescribed, briefly illustrated throughreference to reorganisation, and linked withorchestration. Characteristics of complexitydictated the response of orchestration and thesubordinate complex change management themesacross the different stages of the changeprocess. The analytical model is offered as aconceptual framework for future research thatwould test its wider applicability and as apractical planning tool. The importance isunderlined of developing generic yetcontext-sensitive practical guidance thatreflects the degree of complexity faced byorchestrators charged with managingcontemporary educational change.     

Teaching an Innocence Case Review Course to Undergraduate Students

After two years of experience in overseeing groups of undergraduate and graduate criminal justice students in an Innocence Case Review course at the University of Central Missouri (UCM), the authors reviewed the structure of the course and the attitudes of the participating students. An examination of Innocence Case Review current procedures in undergraduate institutions and law schools provides background for course design. This article summarizes the findings of the students’ experiences, reactions, and attitudes of their yearlong case screening efforts, and to the criminal justice system in general. The first part of this article examines the literature on innocence case review classes at both undergraduate institutions and law schools exploring different learning styles and strategies inherent in this type of class. It also explores the skills necessary for case review, and the skills students can take to other classes and professions. The second part reviews the structure of our courses as initially created and implemented for the last two academic years at UCM and the modifications the instructors felt necessary for the future. The third part examines the survey conducted by the UCM’s Innocence Case Review class, including student suggestions for class improvements and advice to students selected for the new academic year. The benefits and abilities gained by the students through this course become apparent. The fourth part discusses and evaluates the current class structure and reforms suggested by the UCM students, the professors’ experience, and as indicated by other universities. The conclusion reviews findings gathered from the current course as well as examining other universities’ courses, and the value students experience from participating in this experiential or engaged learning.

Darwin's Down house

Six years after his return from the voyage of the Beagle, Darwin moved his family to the country, where he spent the rest of his life conducting experiments, writing, and raising a family. English Heritage recently purchased Down House and is restoring the house and grounds to look as they did during Darwin's life.
