title: Improving student learning? Research evidence about teacher feedback for improvement in New Zealand schools.

authors: Eyers, Gayle

subjects: students

abstract: The importance of giving both evaluative and descriptive feedback to improve learning and achievement has been confirmed through research. This paper draws on assessment and feedback research to interrogate the evidence about how well teachers use feedback in New Zealand classrooms. It reveals that there is very little New Zealand research that investigates NZ teachers' use of feedback. Those studies that do investigate teachers' use of assessment information show that very little of the information gained from assessment is used to inform students about how to improve. More often teachers praise students, give unspecific information about their work and use the data gathered about students' competence and skills for school-wide aggregation and evidence of meeting targets. Questions are raised about why this might be the case, how professional development might be implicated in this and how the situation might be improved through wider policy alignment at both local and national levels.

title: Efficient quantile regression for heteroscedastic models

authors: Jung, Yoonsuh

subjects: check loss function

abstract: Quantile regression (QR) provides estimates of a range of conditional quantiles. This stands in contrast to traditional regression techniques, which focus on a single conditional mean function. Lee et al. [Regularization of case-specific parameters for robustness and efficiency. Statist Sci. 2012;27(3):350–372] proposed efficient QR by rounding the sharp corner of the loss. The main modification generally involves an asymmetric ℓ₂ adjustment of the loss function around zero. We extend the idea of ℓ₂ adjusted QR to linear heterogeneous models. The ℓ₂ adjustment is constructed to diminish as sample size grows. Conditions to retain consistency properties are also provided.

title: Report on the bicultural symposium at conference

authors: Masters-Awatere, Bridgette

subjects: Maori

abstract: Kia ora koutou. I decided to submit the current paper as a way to say thank you to the large group of people in attendance at the bicultural stream at the national conference in late August that was held at Waikato University. It was their continued presence and participation that served as a catalyst and motivator for this paper. I'm conscious that while there was a large number of people in the symposium, there were other streams occurring at the same time, so I thought giving an overview of the success of the symposium would be a good way to let people know who the symposium went. However, before talking specifically about the symposium, I'd like to give mention to other events of the day...
