It's not what you do; it's the way that you question: that's what gets results

Many professionals and carers who support people with the label of autism look to lecturers and 'trainers' in autism to provide the answers on how to 'manage' the 'condition'. This article describes how two lecturers in autism respond to this challenge by encouraging their students to focus on questions rather than answers. It is argued here that it is through the process of reflective thinking that people will find the most appropriate solutions to the issues that concern them. The article identifies some of the key questions that can support the reflective process and illustrates the applicability of these, beyond the limitations of labels, to every relationship between educator and learner.

Western Schooling and Traditional Society in Swaziland

This study analyses the actual and perceived significance of schooling on the lives of rural people in Swaziland. It compares and contrasts the Swazi public's attitudes towards and participation in Western education during the colonial period with the present day. Through interviews with Swazi parents, students and teachers, the study finds that, as during the colonial period, parents feel alienated from the school as an institution. As today's Ministry of Education strives to incorporate a stronger technical aspect to the school curriculum, parents view school as a place primarily for academics. These attitudes are directly related to their keen awareness of the strong correlation between education and modern sector employment. This is particularly notable because now, in contrast to the colonial period, all parents strongly desire a formal education for their children and have high professional aspirations for them.
