Opportunities and challenges with J2SE 5 for introductory programming teaching

The recent release of the Java version 5.0 "Tiger" introduces some significant language changes. For educators, some of these changes provide opportunities to improve teaching, while others pose additional problems that require awareness to avoid them. The authors have recently completed the inclusion of support for all new language features into a wellknown educational IDE for Java – BlueJ – and in the course of doing so evaluated each of them for usefulness in education, and developed pedagogic strategies to handle the inherent opportunities and challenges. This has formed the basis of the design of the features in BlueJ which support the language changes. In this paper, we describe the results of our evaluation, provide recommendations on treatment of the new features in introductory courses and discuss how BlueJ may be used to illustrate important aspects.

Diversity discourses / diversity experiences : teaching for and with cultural diversity

The contexts for 'cultural diversity education' usually reported in the research literature typically involve white middleclass people being prepared for teaching in ethnically diverse classrooms. The emphasis is thus on 'diversity' 'out there' in the classroom, with little acknowledgement of what such diversity education might mean for trainee teachers who themselves either identify as or are classified as culturally diverse. This study examines intercultural interactions reported by ethnically and culturally diverse teacher education students. Their difficulties with making sense of these interactions are described as 'intercultural disjunctions', often affecting personal or professional identity. I ide ntify three dominant discourses in the research literature that attempt to describe such disjunctions and analyse these in relation to the participants' stories. I conclude by outlining some implications for teacher education.
