Partial reinforcement effects on discrimination learning

Rats were trained on a series of reversals of a successive discrimination in which the percentage of S+ trials ending in food was varied. Changes in the discrimination index occurred more slowly with 50% reinforcement than with 100% reinforcement when the number of training trials was equated across conditions, but were approximately invariant when the conditions were equated with respect to the number of obtained reinforcements. Presentation of free reinforcement during the intertrial intervals reduced the overall rate of discrimination acquisition, but left this invariance unaffected. Invariance in reinforcements necessary to attain acquisition also occurred when different discriminations correlated with different percentages of reinforcement were intermixed within experimental sessions. The failure of the invariance effect to be disrupted by either manipulation suggests that previous accounts of the invariance effect in terms of “comparator” models of conditioning (e.g., Gibbon & Balsam, 1981) are inadequate.     

Instructional design and project management: complementary or divergent?

This paper reports the results of a study to identify the extent to which organizations that develop educational/training products are committed to project management, as measured by their project management implementation maturity, as a methodology that is separate and distinct from the processes of instructional design. A Web survey was conducted among 103 public and private sector organizations worldwide that develop educational/training products. Results show no significant difference by project management maturity level in the roles of instructional designer and project manager, although there is some relationship between maturity level and how organizations perceive the skills/competencies of project managers versus those of instructional designers. Further, organizational decision-makers have very specific expectations about the formal education and training of educational/training product development project leaders. The findings should be of value to institutions of higher education in evaluating programs that prepare students for careers in instructional design.     

Leadership and inclusion: a special school perspective

In July 2002, the National College for School Leadership (NCSL) held a 'Leading Edge' seminar focused on the contribution that leaders in special schools can make to the development of Inclusive policies and practices. The day gave colleagues working in specialist contexts an opportunity to share examples and experiences of current initiatives and to speculate about future trends and developments in inclusive education. In this article, Robin Attfield and Chris Williams, Assistant Directors in Programmes and Research respectively at the NCSL, explore the context in which the seminar took place and some of the themes and issues that emerged from discussion on the day. At the end of their paper, they summarise the key messages that the special school leaders who attended the seminar wished to communicate to a wider audience and articulate a further role for leaders in special schools in the development of inclusion.     

Let's keep in contact with Europe — a joint European research project about lifelong education for adults with learning difficulties

The authors of this article come from a range of professional backgrounds in agencies across Europe. Samuel Fernandez lectures at the University of Oviedo in Spain; Janos Kovari works at the Kerek Vilag Foundation in Hungary; Paola Vulterini works for Capodarco, a service provider in Italy; and Val Williams is a researcher at the Norah Fry Research Centre at the University of Bristol. Using funding from the European Commission, the team undertook research into the curriculum provided for adults with learning difficulties in a variety of centres in their four home countries. Fernandez, Kovari, Vulterini and Williams find some interesting similarities and some significant differences in provision. They also seek the views of service users about a common core curriculum derived from their research and present a case for further work in this important area.     

Crossing cultures: Analysing the experiences of NZ returnees from the EU (UK vs. non-UK)

While there is growing scholarly interest in returned and cyclical migration, and on young adult cultural or adventure seeking migration, there is still a lack of systematic empirical insights into how the experiences of being abroad, and after return, are mediated by exposure to different cultural environments. Addressing this conceptual and empirical gap, the paper analyses the experiences of New Zealand return migrants, or sojourners, who lived and worked in European countries (other than the UK) for more than one year and compares them with the experiences of NZ returnees from the UK. Drawing on 20 ‘non-UK’ and 22 ‘UK’ in-depth interviews, the paper revisits [Rhinesmith, 1975] and [Rhinesmith, 1986] typology of cross-cultural, or intercultural, adjustment (largely ignored in studies of return migration) to assess sojourners’ experiences throughout the migration cycle and serve as a useful tool for identifying and reporting psychological and socio-cultural elements in the returnees stories. The findings of sojourners’ possible identity shifts during intercultural transition are discussed with reference to the four-member paradigm of Cultural Identity Model (CIM) (Sussman, 2010) while addressing Sussman's (2002) argument that overseas adaptation and repatriation experiences are not directly associated. This paper demonstrates the need to understand first that the costs and benefits of circular migration or sojourning are country-specific, and that they do not ‘just happen’ at a particular moment or in one phase but are forged through a veritable rollercoaster of experiences of intercultural adjustment.
