title: Voice over distance: a case of podcasting for learning in online teacher education

authors: Forbes, Dianne Leslie

subjects: Social Sciences

abstract: This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal.

title: Distribution of Pfiesteria piscicida cyst populations in sediments of the Delaware Inland Bays, USA

authors: Coyne, Kathryn J.

subjects: Cyst

abstract: The toxic dinoflagellate, Pfiesteria piscicida, is a common constituent of the phytoplankton community in the Delaware Inland Bays, USA. In this study, molecular methods were used to investigate the distributions of benthic stages (cysts) of P. piscicida in sediment cores from the Delaware Inland Bays. Cores from 35 sites were partitioned into nephloid and anoxic layers and analyzed for P. piscicida by nested amplification of the 18S rDNA gene using P. piscicida-specific primers. The presence of inhibitory substances in the PCR reaction was evaluated by inclusion of an exogenous control DNA in the extraction buffer, thus eliminating samples that may yield false-negative results. Our results indicate a patchy distribution of P. piscicida in sediments of the Delaware Inland Bays, with distinct differences between each of the three bays. Overall, P. piscicida was found more frequently in sediments from Rehoboth Bay compared to Indian River and Little Assawoman Bays. These differences suggest (i) that populations of P. piscicida may be more widely distributed in Rehoboth Bay, (ii) that populations of P. piscicida may have been introduced to Rehoboth Bay at an earlier time, (iii) that past blooms of P. piscicida in Rehoboth Bay estuaries may have seeded the sediments with higher numbers of cysts, and/or (iv) that Rehoboth Bay sediments may be more resistant to clearing due to storm turbulence.

title: The challenges of culture to psychology and post-modern thinking

authors: Waldegrave, Charles

subjects: Maori

abstract: Someone at a workshop in the Waikato once said to us, “You know a Maori, if they want to, can always learn to be a psychologist, but a psychologist can’t learn to be a Maori”. Cultural knowledge may or may not be accompanied by social science knowledge. Cultural knowledge can stand on its own. Those who possess it, and choose to work in the institutions we are associated with, have gifts this country desperately needs. All our organisations require such people, and they need to be properly resourced, have employment security and control over their work. Their own work away from our organisations also requires adequate resourcing. They can heal their own in ways that we will never be able to. They will almost certainly offer the field rich alternative metaphors and meanings that can free us from the tired old medical, biological and social science ones. This also has implications for those in other branches of psychology, including research, experimental and industrial psychology. There is perhaps a unique opportunity for psychologists in this country of Aotearoa/New Zealand to recognise other ways of describing events, which will lead to creative practices and enable the health and welfare resources to get to those who most need them, on their own terms. It would also enable other people, other workers from other cultures to develop new paradigms, and new shifts in our field. This will not lead to the abandonment of social science, but it will enable that body of knowledge, to sit appropriately along side other realms of knowledge such as gender knowledge, and cultural knowledge, without dominating. A new experience for the social scientists, but I suspect a liberating one!
