Dissatisfaction, internationally, with existing educational practices and outcomes since the early 1990s has led to increased educational reform. At the same time, there has also been a worldwide shift in control of education away from teachers toward the state for the purposes of restructuring economies. More bureaucratic forms of curriculum and assessment have resulted, with a return to the use of more techno-rational discourse in assessment and evaluation for purposes of efficiency, accountability, impact, and performance management. There has also been an increase in the use of economic and productivity models to study educational outcomes. These models fail to account for the range of outcomes achieved and fail to identify the factors responsible for such diversity in performance.

The United Arab Emirates (UAE) is part of the geographic region known as the Middle East. With a land mass of 82,000 square kilometres, predominantly desert and mountains it is bordered by Oman, Saudi Arabia and the Arabian Gulf. The UAE is strategically located due to its proximity to other oil rich Middle Eastern countries such as Kuwait, Iraq, Iran, and Saudi Arabia. The UAE was formed from a federation of seven emirates (Abu Dhabi, Dubai, Sharjah, Ras Al Khaimah, Ajman, Fujuriah, and Um Al Quain) in December 1971 (Ras Al Khaimah did not join the federation until 1972) (Heard-bey, 2004, 370). Abu Dhabi is the political capital, and the richest emirate; while Dubai is the commercial centre. The majority of the population of the various Emirates live along the coast line as sources of fresh water often heavily influenced the site of different settlements. Unlike some near neighbours (Iran and Iraq) the UAE has not undergone any significant political instability since it was formed in 1971. Due to this early British influences the UAE has had very strong political and economic ties with first Britain, and, more recently, the United States of America (Rugh, 2007). Until the economic production of oil in the early 1960’s the different Emirates had survived on a mixture of primary industry (dates), farming (goats and camels), pearling and subsidies from Britain (Davidson 2005, 3; Hvit, 2007, 565) Along with near neighbours Kuwait, Bahrain, Oman, Qatar and Saudi Arabia, the UAE is part of the Gulf Cooperation Council (GCC), a trading bloc. (Hellyer, 2001, 166-168).

In this chapter we introduce a theoretical framework for studying decision making in sport: the ecological dynamics approach, which we integrate with key ideas from the literature on learning complex motor skills. Our analysis will include insights from Berstein (1967) on the coordination of degrees of freedom and Newell's (1985) model of motor learning. We particularly focus on the role of perceptual degrees of freedom advocated in an ecological approach to learning. In introducing this framework to readers we contrast this perspective with more traditional models of decision-making. Finally, we propose some implications to the training of decision-making skill in sport.

Traditionally, the aquisition of skills and sport movement has been characterised by numerous repetitions of presumed model movement pattern to be acquired by learners. This approach has been questioned by research identifying the presence of individualised movement patterns and the low probability of occurrence of two identical movements within and between individuals. In contrast, the differential learning approach claims advantage for incurring variability in the learning process by adding stochastic perturbations during practice. These ideas are exemplified by data from a high jump experiment which compared the effectiveness of classical and a differential training approach with pre-post test design. Results showed clear advantages for the group with additional stochastic perturbation during the aquisition phase in comparison to classically trained athletes. Analogies to similar phenomenological effects in the neurobiological literature are discussed.

Broadly speaking, axiology is the study of values. Axiologies are expressed materially in patterns of choices that are both culture-bound and definitive of different cultures. They are expressed in the language we use; in the friends we keep; in the clothes we wear; in what we read, write, and watch; in the technologies we use; in the gods we believe in and pray to; in the music we make and listen to—indeed, in every kind of activity that can be counted as a definitive element of culture. In what follows, I describe the axiological underpinnings of two closely related multimedia repository projects— Australian Creative Resources Online (ACRO) and The Canadian Centre for Cultural Innovation (CCCI)—and how these are oriented towards a potentially liberating role for digital repositories.
