‘The sky is the limit’: higher education,gender and empowerment in the Bedouin community in the Negev in Israel

This article addresses the meaning that female Bedouin from the Negev in Israel give to higher education. I shall focus the discussion on the processes in which personal and social contexts merge into one another. Although there has been an increase in the number of investigations of the ways in which Bedouin women in the Negev in Israel participate in the public sphere, a survey of the literature reveals that no investigations have been conducted on the meaning educated women attribute to higher education during the course of their lives. Through an analysis of ten in‐depth interviews carried out between 1998 and 2001, this article examines issues such as gender, empowerment and social mobility amongst young Bedouin women in Israel.

ACHIEVEMENT MOTIVATION OF INTELLECTUALLY GIFTED STUDENTS WHEN CONFRONTED WITH CHALLENGING AND UNCHALLENGING TASKS

Two groups of gifted adolescents solved two similar intelligence tests with differing levels of task difficulty in reverse order. Under both conditions the performance level on the less complex test was much lower, a result not observed in a control group of average intelligence. Behavioural observations revealed that the low performance of the gifted students was combined with lack of effort. This performance pattern is discussed with respect to recent postulates of achievement motivation theory, which empasize the impact not only of the achievement motive, but also of the informational value of a given task for evaluating own level of ability. It is argued that the perceived informational value of the easier test was not high enough to create an incentive for the gifted students to perform at the highest possible level
