title: Location-based vocabulary learning app

authors: Wu, Shaoqun

subjects: computer science

abstract: This paper presents a mobile app that generates vocabulary learning games based on the user’s geographical location—cinema, restaurant, museum, etc. The app sends the user a notification and offers three fun vocabulary games—Unscramble, Hangman and Matching—when the user enters the premises of the location of interest. This project used cinema halls as the primary location. The games are automatically generated from the movie words and phrases extracted from New York Times movie reviews. The user can either learn new words or review words learned previously. A preliminary study with seven language learners has shown learners’ positive attitude towards the underling principles of location-based vocabulary learning. It has also provided constructive feedback for the future development.

title: Shifting deficit perspectives of teacher-parent partnerships: Post-covid teacher stories

authors: Vale, Pamela

abstract: In this oral communication we focus on primary school mathematics teacher practices, in the post-Covid context, that enabled (or not) mathematical learning partnerships with parents, and the parent responses to these practices, as storied by the teachers. We address the questions: (1) How are primary school mathematics teachers engaging with and supporting parents in the post-Covid context, particularly regarding supporting learners’ mathematical learning? and (2) How are parents (according to teachers) responding to the efforts of teachers to encourage their engagement with the mathematical learning of their child?

title: Monitoring and hydrodynamic modelling of groundwater inflows into Lake Rotokakahi, New Zealand

authors: Noakes, Katie

subjects: Groundwater

abstract: Lake Rotokakahi is located 10 km south of Rotorua and is of immense cultural importance to the local iwi. The lake also has significant historical and recreational values, which prompted iwi to make the lake private in 1996. Lake Rotokakahi is one of several Rotorua/ Te Arawa lakes. Several of these lakes have become eutrophic and some have declining water quality. This study was prompted by declining water quality of Lake Rotokakahi and the need to identify potential sources of nutrients to the lake, particularly groundwater inflows.

The interaction between groundwater and surface water has a major influence on the trophic status of lakes, particularly those that are predominantly or solely groundwater fed systems. Lake Rotokakahi has one small spring-fed surface water inflow and one outflow, the Te Wairoa stream. Thus the lake is predominantly groundwater fed. The main objective of this thesis was to quantify the contribution of groundwater and surface water to Lake Rotokakahi and to examine interactions of the groundwater system with the lake, in order to provide a basis to improve lake management practices. Multiple monitoring sites were established around the perimeter of the lake to determine the spatial and temporal variation of groundwater inputs, as well as the groundwater nutrient dynamics. A three-dimensional hydrodynamic lake model was set up and simulations were used to examine how groundwater and surface water inflows were dispersed within the lake upon entry.

Monitoring of the shallow groundwater system took place from 1 January to 1 July 2016. Three separate storm events were monitored at high frequency within this monitoring period. The monitoring results showed the groundwater system varied significantly both spatially and temporally and also contributed a high proportion of the total nutrient load to the lake. Groundwater discharge and nutrient concentrations generally increased in association with or immediately following high rainfall events.
 
The three-dimensional model ELCOM was set up using hydrological data for the catchment, meteorological data from a nearby station and bathymetry of the lake. Simulations were based upon different methods of calculating groundwater inflows. Simulation 1 was based upon the common water balance equation method. Simulation 2 used constant groundwater inflow and outflow volumes as determined by a groundwater flow model, MODFLOW, which had been applied to the catchment by White et al., (2015). Simulation 3 combined MODLFOW values and measured groundwater levels to create a varying inflow volume based on water level. The three simulations accurately captured surface and bottom temperatures and had varying lake water levels. Only simulation 3 accurately captured the presence of the groundwater spring near the lake shore and was concluded the more accurate method of groundwater inflow calculation.
