Changing Roles and Professional Challenges for Human Performance Technology

From its roots in behavioral science and instructional systems design, the field of human performance technology has broadened significantly during the past three decades in terms of its interventions and the backgrounds and skills areas of its practitioners. This development brings with it many questions as to the field's definition, theoretical underpinnings, and future developments in research and practice. A brief review of the history of HPT, a survey of some of its leaders, and a model of the roots and branches of the field are presented.     

Developing a School Focused Approach to Continuing Professional Development in Sustainability Education

This article has two aims. Its first is to describe how findings from a questionnaire survey of 96 UK primary schools influenced the theory of action adopted in the SEEPS Project, (Sustainability Education in European Primary Schools, 1997) funded by DGXI and DGXXII of the European Commission and Scottish Natural Heritage. SEEPS is a continuing professional development (CPD) project developed by representatives from 11 European educational systems. The first section of the article outlines how the Project came to adopt a school focused theory of action in CPD, in preference to a centralised or school-based approach. School focused CPD trains trainers and provides them with adaptable materials that can support individualised CPD programmes decided in and by the school and its staff. The second aim is to outline and analyse some of the more interesting inter and intra-regional relationships, correlations and differences which emerged from the survey. We have only included those findings that illuminate CPD provision in sustainability education. This article seeks to share data with others working in environmental education and sustainability education and to stimulate a debate about the relevance of school focused approaches in international discussions about CPD in environmental and sustainability education.     

An elemental model of associative learning: I. Latent inhibition and perceptual learning

This paper presents a brief, informal outline followed by a formal statement of an elemental associative learning model first described by McLaren, Kaye, and Mackintosh (1989). The model assumes representation of stimuli by sets of elements (i.e., microfeatures) and a set of associative algorithms that incorporate the following: real-time simulation of learning; an error-correcting learning rule; weight decay that distinguishes between transient and permanent associations; and modulation of associative learning that gives high salience to and, hence, promotes rapid learning with novel, unpredicted stimuli and reduces the salience for a stimulus as its error term declines. The model is applied in outline fashion to some of the basic phenomena of simple conditioning and, in greater detail, to the phenomena of latent inhibition and perceptual learning. A detailed account of generalization and discrimination will be provided in a later paper.
