title: The role of existing knowledge in reading comprehension and conceptual change in science education

authors: Bell, Beverley

abstract: Recent research in science education has illustrated that students, prior to formal science teaching, have constructed for themselves interpretations of and explanations for many natural phenomena, and that these beliefs may persist despite up to five years of science tuition. The research has also demonstrated that these beliefs, which are part of a student’s existing knowledge, are an important factor in determining what learning, if any, will occur. This has led to the development of a view of learning in science as conceptual change, rather than concept acquisition, and as an active, constructive process rather than a passive, absorptive one. This view (and in particular the generative learning model) has been adopted in this study. 
A parallel development in reading research has also emphasised the role of existing knowledge in reading comprehension and a view of reading comprehension as the active construction of meaning.
The current research spanned both these two related fields of reading comprehension and conceptual change in science education and focused on the role of existing knowledge in both processes. In particular, it investigated the role of existing knowledge (for example, the everyday meaning of ‘animal’) of some 13-year-old students in comprehending a text about the scientific concept of animal, and in what ways this influenced conceptual change.
Three different methodologies were used - one in each of the three phases of the research programme. These were the qualitative interview techniques (the ‘spot-the-mistake’ and ‘reading-to-learn’ interviews) and quantitative survey measures.
The findings gave further support to a constructivist view of reading comprehension and conceptual change, and a strong interactionist view of reading comprehension was suggested, as existing knowledge not only contributed to the constructed meanings, but influenced what constructions were made.
The main finding was that existing knowledge was used not only to construct a meaning but to evaluate it in terms of whether to accept or reject the construction. Learning in science, therefore, involves not only the construction of the intended meaning, but accepting it as well. Learning difficulties may occur at either the construction or acceptance stage. The results suggested that in science education, students’ difficulties in accepting a scientific construction may be as great as, if not greater than, those in constructing the scientific conception itself.
The implications of the findings for teaching and learning, the curriculum, reading in science classrooms and textbook authors are discussed in the final chapter.

title: Where geology meets pedology: Late Quaternary tephras, loess, and paleosols in the Mamaku Plateau and Lake Rerewhakaaitu areas

authors: Lowe, David J.

abstract: On this trip we focus on tephrostratigraphy and soil stratigraphy together with aspects of palaeoenvironmental reconstruction over long and short time-spans. We will examine the relationship between the deposition of tephras and tephric loess and the formation of soils in these deposits as they accumulate, either incrementally (millimetre by millimetre) or as thicker layers, in a process known as upbuilding pedogenesis. Development of age models for the eruption of marker tephras, and of the new climate event stratigraphy for New Zealand within the NZ-INTIMATE project (Integration of ice-core, marine, and terrestrial records for New Zealand since 30,000 years ago), will also be touched upon.

title: Too many Māori and Asian people are drowning – can better cultural understanding reverse the trend?

authors: Wheaton, Belinda

abstract: The article discusses the high rate of drownings in New Zealand, particularly among Māori and Asian communities. It highlights the need for culturally specific water safety education to address this issue. The Asian community, in particular, includes many first-generation migrants who may lack water skills due to their upbringing and fear of water. Overprotectiveness towards children around water is also common among Asian parents. The article emphasizes the importance of providing support and learning opportunities to help Asian migrants develop water skills and feel more comfortable in outdoor activities. Additionally, it mentions the declining water skills among New Zealand children in general and the need for better resourcing of school programs and community initiatives like ActivAsian. Culturally relevant knowledge and education are deemed crucial in changing attitudes and behaviors towards water safety. The article stresses that making New Zealand's beaches and waterways safe for all residents, including migrants, requires targeted funding and a collaborative effort to prevent tragic drowning incidents.
