We share the impact different models have on students' fraction thinking. We have come to understand, through several teaching experiments, how fraction circles, paper folding and number lines support students' learning about key fraction ideas including the role of the unit, partitioning, and fraction order.

AbstractWhat does learning in today's technology-enhanced environment mean? Is learning as an activity fundamentally changing as a result of the opportunities offered by new technologies and tools? How are the new communicative channels and increased social dimensions possible through Web 2.0 technologies impacting on the way students work and learn? And what does this mean for the role of teachers and institutions in terms of how they support students? This paper considers these questions and reports on findings from current research evaluating how students are actually using technologies and what this research tells us about the ways in which patterns of learning might be changing. It will consider the implications for individual teachers (in terms of designing and supporting learning activities for students) and institutions in terms of the impact on policy and the associated infrastructure needed to provide an appropriate environment that maximises the potential offered by new technologies.

This paper reports on a pilot project in which two postgraduate students were supported to function in the role of teaching assistants (TAs) as part of their learning experience. The project embraced the notion of students as producers rather than consumers. Using a reflective approach, this case study was jointly written by TAs and their teaching staff. It incorporates feedback from other students collected through an anonymous module feedback survey, which was analysed by attribution to themes. The role of TAs benefitted others students, staff, and the TAs; the project is a strong affirmation of the principle of treating students as producers. The impact of the role on both the students undertaking the TA role and the tutors was profound, and student experience was enhanced as a result. TAs can assist in bridging student-teacher communication gaps and support students’ learning through sharing their knowledge by creating resources. This article is written from the perspectives of both the TAs and the tutors.

Two studies examined the impact of macrolevel symbolic threat on intergroup attitudes. In Study 1 (N = 71), participants exposed to a macrosymbolic threat (vs. nonsymbolic threat and neutral topic) reported less support toward social policies concerning gay men, an outgroup whose stereotypes implies a threat to values, but not toward welfare recipients, a social group whose stereotypes do not imply a threat to values. Study 2 (N = 78) showed that, whereas macrolevel symbolic threat led to less favorable attitudes toward gay men, macroeconomic threat led to less favorable attitudes toward Asians, an outgroup whose stereotypes imply an economic threat. These findings are discussed in terms of their implications for understanding the role of a general climate of threat in shaping intergroup attitudes.
