title: Induction of model trees for predicting continuous classes

authors: Wang, Yong

subjects: computer science

abstract: Many problems encountered when applying machine learning in practice involve predicting a "class" that takes on a continuous numeric value, yet few machine learning schemes are able to do this. This paper describes a "rational reconstruction" of M5, a method developed by Quinlan (1992) for inducing trees of regression models. In order to accommodate data typically encountered in practice it is necessary to deal effectively with enumerated attributes and with missing values, and techniques devised by Breiman et al. (1984) are adapted for this purpose. The resulting system seems to outperform M5, based on the scanty published data that is available.

title: ‘Shoot for the moon!’ Students' identities as writers in the context of the classroom

authors: Wearmouth, Janice

subjects: student writing identities

abstract: A study of students' identities as writers was carried out in the classroom of a New Zealand primary teacher who had been formally identified by a national body of teachers as having excellent practice in supporting literacy acquisition. The researchers, Professor Janice Wearmouth, from the University of Bedfordshire, Mere Berryman, from the University of Waikato, New Zealand, and Lisa Whittle, from the Department of Conservation, Wellington, New Zealand, aimed to compare high and low literacy achievers' identities as writers within the context of this teacher's pedagogy and the learning environment of her classroom. The researchers concluded that all students, both high and low achievers, were developing very positive writing identities in a context where the teacher's method of supporting her students' writing was very well planned through a process-writing approach. This teacher had a very high degree of subject and pedagogical content knowledge and an acute awareness of her students' literacy learning needs. Her approach had an immediacy of responsiveness in relation to every student's learning and, above all, had recognition of the overwhelming importance of positive relationships in the classroom, teacher to student and peer to peer.

title: Hone Werahiko: the discoverer of gold at Te Aroha

authors: Hart, Philip

abstract: Originally Hone Kahukahu, when he was living at Ohinemutu in the 1860s he became known as Hone Werahiko, an Arawa name he retained for the rest of his life. His father, a member of Ngati Kahungungu, had been captured by Arawa; his mother was a Waikato. A widow living at Maketu chose him as her second husband because he was ‘a good looking fellow & understood English’. 
In the late 1860s and much of the 1870s, he prospected in Hauraki and even in the King Country, and worked underground in a Thames mine, the only Maori known to have done so. But in the early 1870s he gave up mining to be a pioneer publican and storekeeper at Ohinemutu, at Rotorua. He acquired land and property there, but after his wife died he returned to prospecting full-time. 
Werahiko’s first investigation of Te Aroha was in 1877, when he was ordered off by the local hapu. He returned in 1880 as the head of a prospecting party subsidized by the government. After finding gold, he was granted the Prospectors’ Claim and, in due course, a reward, and for a time supervised its development. Investing in other claims, he traded in shares. When his discovery turned out to be a duffer, he explored other parts of the mountain, first having high hopes for the Tui portion but then, after four months of exploring over winter with the support of three other Maori, he announced the discovery of his New Find at Waiorongomai. Once again he acquired partners, mostly Paheka, and traded in shares, and for some time supervised the opening up of his new find.
Later, he was invited to prospect the King Country, but this did not eventuate. His last involvement in mining was at Karangahake. Because of the hardships of his prospecting at Te Aroha, he died at an early age, leaving a young second wife. His memory lived on, amongst Pakeha miners in particular, because he had the rare distinction for a prospector of being regarded as totally honest, and he was admired for succeeding when so many others had failed.

[Note: Especially when he first came to public attention, many Pakeha struggled with Hone Werahiko’s name, which was recorded in a variety of incorrect forms, the worst example being Hoani Whaekareka.  Even the warden at first gave his name as Hone Wharekino.  Many Pakeha found it simpler to refer to him as ‘Johnny the Maori’.  In this paper, his name is given correctly throughout.]
