title: Learning perspectives: Implications for pedagogy in science education.

authors: Cowie, Bronwen

subjects: learning

abstract: How we understand learning has implications for the learning outcomes we value and how we seek to achieve them particularly when we want to do something about learning. In this paper I outline, albeit briefly, the implications for the relations between teaching and learning,for teacher roles and responsibilities, and for the goals of education and curriculum-making of the cognitive-constructivist and situated-social views of learning. The proposal here is not that either of the views is right or better but rather that each foregrounds different aspects of the teaching-learning process and supports particular ways of acting and interacting and hence learning and teaching.

title: Learning Through Utility Optimization in Regression Tasks

authors: Branco, Paula

subjects: Science & Technology

abstract: Accounting for misclassification costs is important in many practical applications of machine learning, and cost-sensitive techniques for classification have been studied extensively. Utility-based learning provides a generalization of purely cost-based approaches that considers both costs and benefits, enabling application to domains with complex cost-benefit settings. However, there is little work on utility- or cost-based learning for regression. In this paper, we formally define the problem of utility-based regression and propose a strategy for maximizing the utility of regression models. We verify our findings in a large set of experiments that show the advantage of our proposal in a diverse set of domains, learning algorithms and cost/benefit settings.

title: !!!FR33D0M 0FF SP33CH!!!

authors: Smith, Hugh Lyal

subjects: Poetry

abstract: My title is “FR33D0M 0FF SP33CH”, a play on the saying “freedom of speech”. I write with the intent of voicing tough subjects that others haven’t or don’t, and often exposing things that I wouldn’t tell or share personally. “FR33D0M 0FF SP33CH” consists of 37 poems, 2 hooks and a chorus in this complete album. My earliest piece can date back to 2020 with the latest pieces being written in 2021. They express different visions of day-to-day life through points of view and alternating voices and perspectives. The topics range from anything like seeing a face in the smudge on a wall, to things like love, street styles and why I can’t sleep at night. They are to be read left to right, top to bottom -- but feel free to read them as you see fit, because it’s art after all and what you see is what you see. Those labelled “Mirrored” have been turned upside down to allow reading from either end and show the extent of form and variety my pieces can take. Some things may be explicit or hard to read, but I assure you that they are just certain views from different angles that I believe need to be shared. There is a strong political/cultural component to my mahi, a tough vocal attack on elements of society I believe are flawed and unjust, and an exposure of the addictions and abuses that colonial history and racial inequality lead to – but there’s also an intense celebration of the power of the Māori voice that remains, its beat and pride and resilience and ancestry, joined by a rich musical joy in the songs of the street I grew up in, their rhythms and rap, energy and power. It has taken me a long time to reach this level of writing in terms of technique, rhythm and content. I want the reader to see things through my shades and feel what it feels like to be me with an understanding of why I am and where I come from. To understand that, No, I don’t know everything, and I don’t expect anyone else to. But, Yes, this is what I saw, felt and how I interpreted it. So there it is and this is me, the bro Hugh. A lit ūrikā descendant of Ngāti Kuri, Ngāti Rēhia, Te Rārawa, Te Aupōuri and Ngāpuhi. Bred in the streets I-roam and made home. A dreamer of the future. Last but not least, your son, your brother, your bro and he who wrote the killer book that you are about to read. Churrr!!!
