Until recent times, most studies on supporting simulation-based scientific discovery learning adopted the ad hoc strategies-oriented approach. This paper makes a systematic analysis of the internal conditions of scientific discovery learning to propose a triple scheme for learning support design that includes interpretative support (IS), experimental(More)
Learning support studies involving simulation-based scientific discovery learning have tended to adopt an ad hoc strategies-oriented approach in which the support strategies are typically pre-specified according to learners’ difficulties in particular activities. This article proposes a more integrated approach, a triple scheme for learning support design(More)
Surveys conducted after a crude oil spill indicated that the intertidal gastropod mollusc Austrocochlea porcata may be highly sensitive to the pollutant, and therefore also valuable as a biomonitoring organism. Toxicity tests conducted in the laboratory and field established cause-effect for A. porcata mortalities on exposure to environmentally relevant(More)
The structure and function of agricultural stream reaches with sparse riparian and floodplain vegetation differ from those of forested reaches, but may be ‘reset’ as these streams flow through reaches with forested riparian zones. We investigated whether invertebrate colonisation of River Red Gum (Eucalyptus camaldulensis) leaf packs in lowland intermittent(More)
