Development of system thinking skills in the context of earth system education

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc.

Home: A Feeling Rooted in the Heart

Culturally diverse as they are, Asian-American children and youth share quite a few features among themselves. Most of them are children of foreign-born parents who came to America during the post-1965 immigration waves. As they grow up in culturally isolated environment, they are often faced with identity crisis. The society’s racial exclusion makes them feel like “forever foreigners,” while at home or community their American frame of reference is often in conflict with parents’ traditional values. As a result, they develop a flexible concept of identification. In fact, they are a part of but also apart from the American mainstream culture.     

‘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.
