title: How are science teachers using their TELA laptop?

authors: Cowie, Bronwen

subjects: laptops

abstract: The Digital Horizons: Laptops for teachers scheme provides teachers whose schools opt into the TELA scheme access to a laptop for their exclusive use. This paper reports on a three-year evaluation of the impact of the TELA laptops on teachers’ work. The findings of the evaluation suggest teachers are making substantial use of the laptop for tasks such as lesson planning and preparation, reporting to parents and communication with colleagues. Teachers are making some use of the laptop in the classroom for teaching and learning. Science teachers are amongst the most active users of the laptops and the paper details how ongoing access to a laptop changed the way a third year science teacher planned for teaching and subsequently his interactions with students during lessons. Colleagues and the science head of department noted that the teacher provided a role model for what was possible. This case study highlights the importance of leadership and collaboration in supporting the integration of ICT into science teaching and learning.

title: Measuring stream macroinvertebrate responses to gradients of vegetation cover: when is enough enough?

authors: Death, Russell G.

subjects: biodiversity

abstract: 1. Management of stream biodiversity is often tightly linked with the restoration and protection of riparian and catchment vegetation. Despite that, there are no established guidelines on how much forest should be retained or replanted in riparian zones and surrounding catchments to maintain or re-establish instream ecological integrity. In this study, we assess relationships between vegetation cover at multiple spatial scales (reach, segment and catchment) and macroinvertebrate metrics that reflect community structure, ecological condition and biodiversity at 138 Waikato, New Zealand, stream sites sampled in 2006.
2. Percentage of catchment vegetation in native forest had stronger relationships with measured diversity and condition metrics than segment or reach scale measures of riparian vegetation. Functional feeding group metrics were weakly associated with upstream catchment vegetation cover.
3. Of the macroinvertebrate metrics tested, the RIVPAC O/E and an organic pollution tolerance metric based on species presence–absence (Macroinvertebrate Community Index; MCI) had the strongest relationships with percentage native riparian vegetation, followed by the quantitative MCI and measures of the richness and relative abundance of Ephemeroptera, Plecoptera and Trichoptera faunas. The O/E and MCI indicated that catchments with 80–90% in native forest or scrub (low-growing trees) were associated with faunas indicative of "clean" water quality.
4. Of the biodiversity indices considered Fisher's α Index of species richness had the strongest relationship with percent native riparian vegetation in the upstream catchment. There are no established thresholds for measuring biodiversity loss in New Zealand streams, but this analysis indicates that on average streams draining catchments with 40–60% upstream native vegetation cover retain 80% of the mean biodiversity present in pristine forest streams.
5. This research indicates that riparian management aimed at enhancing macroinvertebrate biodiversity and the ecological condition of streams is likely to be more successful when focused on protecting and/or restoring headwater catchments rather than short stretches of stream.

title: Ethics in Maori research: Working paper

authors: Cram, Fiona

subjects: Maori

abstract: When we think about what we are doing as researchers, one of our main tasks is to acquire knowledge. For some researchers their task begins and ends there. Knowledge is viewed as cumulative, that by adding to some knowledge pool we will one day be able to put the component parts together and discover universal laws. Many researchers also assume that the knowledge they have collected is objective, value-free and apolitical. This is part of psychologists’ ‘physics envy’. A Maori view of knowledge is very different from this. For Maori the purpose of knowledge is to uphold the interests and the mana of the group; it serves the community. Researchers are not building up their own status; they are fighting for the betterment of their iwi and for Maori people in general.
