title: Deepening students' understanding of multiplication and division by exploring divisibility by nine

authors: Young-Loveridge, Jennifer

subjects: education

abstract: This paper explores how a focus on understanding divisibility rules can be used to help deepen students’ understanding of multiplication and division with whole numbers. It is based on research with seven Year 7–8 teachers who were observed teaching a group of students a rule for divisibility by nine. As part of the lesson, students were shown a way of proving why the divisibility rule for nine works, using materials grouped in tens and hundreds. After the lesson, students’ understanding of multiplication and division was considerably deepened.

title: Context-awareness in the wild: An investigation into the existing uses of context in everyday life

authors: Pascoe, Jason

subjects: computer science

abstract: It is common for literature on context-awareness to focus on specific application domains or on the development of models and frameworks to facilitate context-awareness. In this study, however, we take a step back from such work in order to investigate how regular people may already be employing, or trying to employ, context-awareness in their everyday lives using existing mobile tools (such as mobile phones, paper notepads, etc.). We believe that an understanding of these existing real-world uses and needs of context-awareness will help to better inform and direct research efforts in this domain. Towards this aim we present the findings of a user study in which twelve randomly selected individuals recorded a diary on their use of mobile tools over the period of two days. The findings clearly demonstrate that people do indeed currently employ a wide variety of contexts and context-aware behaviours, albeit in a manner that is often imperfect and at a sub-conscious level.

title: Lake weed and the Rotorua Te Arawa Lakes then and now

authors: Burton, Tracy

abstract: This afternoon we will be looking beneath the surface of the Rotorua
Te Arawa lakes at the submerged aquatic plants that grow within them – the good the bad and the ugly. We will have a look at the special native aquatic plants that occur naturally in the lakes, familiarise ourselves with the weed species that have invaded them and look at how these weeds have (and are) changed the natural condition of the lakes. We will also look at how submerged plants are being used to report on the condition of our lakes and what these plant communities can tell us about the state of the lakes yesterday and today.
