Reliability and validity of a Turkish version of the DELES

The primary aim of this study was to examine the reliability and validity of a Turkish version of the Distance Education Learning Environment Survey (DELES) in post-secondary distance education. The second aim was to investigate empirically the conceptualisation of the distance education learning environment as a singular latent construct, within a second-order factorial structure that consists of six first-order factors. The DELES is a 34-item instrument for assessing social-psychological perceptions among distance education students. The tested hypotheses concerned key antecedents and consequences of the factorial structure of DELES in the Turkish context using confirmatory factor analyses. Principal component analysis of the Turkish data revealed six main factors of interest, which corresponded to the hypothesised constructs in the original DELES. The data suggested good reliability and validity for the Turkish DELES (DELES-TR) relative to the original version. Further, second-order analyses were conducted with two complementary samples to demonstrate the validity of six dimensions of the DELES-TR and their contributions to an overall factorial structure of social-psychological learning environment in distance education. Initial support for the second-order factorial validity of DELES-TR was found. Results indicate that a dimensional model of DELES-TR with the six first-order factors provided a superior fit to the data than first-order DELES-TR with six factors. Additionally, an investigation was conducted regarding associations between the DELES-TR’s psychosocial scales and a student satisfaction scale. This study is unique in its focus on the learning environment in distance education in the Turkish setting.     

Optimal stabilization for differential systems with delays - Malkin’s approach

The paper considers a process controlled by a system of delayed differential equations. Under certain assumptions, a control function is determined such that the zero solution of the system is asymptotically stable and, for an arbitrary solution, the integral quality criterion with infinite upper limit exists and attains its minimum value in a given sense. To solve this problem, Malkin’s approach to ordinary differential systems is extended to delayed functional differential equations, and Lyapunov’s second method is applied. The results are illustrated by examples, and applied to some classes of delayed linear differential equations.     

Neoliberal Education Reform in The Netherlands

Until recently the Dutch education system was determined by the historic compromise of 1917, after which private schools were supported by the state on an equal financial footing to state schools. The consequence of this compromise was a mainly privatised and centralised system with a corporatist policy structure. In the mid-1980s The Netherlands, like other countries, came under the spell of the 'neoliberal revolution'. This article explores the extent to which the management reform carried out under a neoliberal flag has brought about radical changes to the Dutch education system. It especially looks at four key issues set out in that reform: increased autonomy, freedom of choice, privatization and quality control.     

Developmental and Educational Perspectives on Theory Change: To Have and Hold,or To Have and Hone?

Eric Schwitzgebel presents an attractive argument for the use of affective indicators to both assess and extend the 'theory theory' research agenda. A key component of his argument is an account of explanation that can be applied to both children and adults, few of whom possess the attributes and behaviors that warrant being called scientists. The core features of his account include 1) regarding a set of propositions as a theory and 2) subscribing to a theory by accepting and employing this set of propositions to explain events within the theory's domain. We will argue that this account, while potentially helpful for guiding research on the affective content of explanations, requires elaboration because it (1) does not fully characterize what is distinctive and important about theoretical and scientific thinking, (2) raises questions about different kinds of explanations, such as seen in transitions from common-sense explanations to theoretical explanations; (3) favors individual theorizing to the exclusion of socially mediated theorizing, and (4) raises developmental questions about the nature of explanation-seeking and the capacity to apply evidence to evaluate theories.     

Policies for disadvantaged children under scrutiny: the Dutch policy compared with policies in France,England, Flanders and the USA

This article reviews the policies for disadvantaged children in western countries since the mid‐sixties. First, it analyses the design and results of the ‘classic programmes’ of positive discrimination such as the American Title I programme, and the English, Dutch, Flemish and French priority areas policies. It discusses the differences and similarities in approach and the disappointing results. Second, the article explores some of the ‘alternatives’ such as pre‐schooling, reducing class size, restructuring the school year, and teacher incentives.     

Cross‐cultural Collaboration in Special Teacher Education: An arena for facilitating reflection?

The present study explored how cross‐cultural collaboration involving university lecturers from Norway (the North) and Egypt (the South), and student‐teachers from Egypt, can be an arena for facilitating student‐teachers’ reflection and for challenging student‐teachers’ preconceived beliefs and perspectives about disability and education. The findings, based on interview data, showed that an emphasis on reflection, exploration and evaluation rather than on drills and repetition was both unexpected and unfamiliar for most of the Egyptian student‐teachers. Some of the Egyptian and some of the foreign lecturers were able to encourage student‐teachers to reflect, although some of the foreign lecturers had a tendency to lecture as they had done at home. Lecturers who wanted to pursue teaching methods that enhanced reflection needed to prioritise time for this, even if the majority of the student‐teachers asked for more information, more facts and for presentations of “the right methods” for teaching learners with disabilities. As the findings in this study illustrate, the partner in the North carries a major responsibility for critically considering the request for expertise because the participants in the South may not necessarily question and challenge the authority of well‐educated professionals from the North. It may not be sufficient for lecturers and supervisors to be well‐qualified practitioners within their home culture. They should be context sensitive, have an inquiring and accepting attitude, and experience challenges, encounters and exposures in the project country over time. Competence in approaches in teacher education is also required, although this meta‐competence may not be explicitly requested by those concerned.     

Using concept maps to elicit and study student teachers’ perceptions about inclusive education: a Tanzanian experience

In this study, concept map activities were used to trigger group discussions about inclusive education, with a focus on learners with disabilities. The participants were 226 Tanzanian student teachers. This article reports and discusses how the maps were analysed and what they indicate about the students’ thinking about certain aspects of inclusive education. The results also indicate that concept mapping as an activity in teacher education may be useful and engaging for students. It may help them to organise knowledge and make them aware of their own and others’ understanding of inclusive education practices. An analysis of concept maps constructed by student teachers may also help lecturers to identify views, misconceptions, knowledge gaps and insights about inclusion in education settings.
