title: An Examination of the Effectiveness of Precision Teaching

authors: McQuarters, Desiree Julia Bettina

subjects: precision teaching

abstract: This research examined the effect of adding precision teaching to an already used method of times table practice, compared practice with and without precision teaching, and finally compared precision teaching to rate building.  In the first experiment there was no significant difference in students' rates, endurance, stability, application or adduction of answering times table equations, depending on whether or not they had received precision teaching.  Due to some confounding variables in the first experiment, a second experiment was performed where these variables where better controlled.  The results from the second experiment also showed no significant difference in students' rates of answering time's table equations, or their retention of these rates, between students who had received precision teaching and those who had not.  Again due to some confounding variables preventing a good comparison of practice with and without precision teaching, a further experiment was conducted.  As the third experiment was conducted in the same setting as the second, precision teaching was compared to rate building instead of practice with no precision teaching.  The results of this study suggest that rate building results in significantly larger increases in rates of answering times table equations than precision teaching.  While there was a significant difference between the two groups' increases in rate, there were some confounding variables that may have affected the outcome of this study.  Overall, students in all three experiments made increases in rate that are comparative to gains reported in the precision teaching literature.  As such while this research does not add support for all the methods used in precision teaching, as described in the literature, it does suggest that the use of rate building results in the achievement of faster rates.

title: The changing face of Lake Okataina’s ‘phosphorus scape’: Who is the culprit?

authors: Kpodonu, Theodore

abstract: Lake sediments contain a great wealth of data on biogeochemical and limnological processes of historical importance, which can be used to interpret natural ecosystem dynamics, and climatic and anthropogenic impacts. In this study, this information was used to understand the dynamics of phosphorus speciation in deep Lake Okataina, to assist with understanding how changes in the catchment influence lake productivity. A 49-cm sediment core was retrieved from Lake Okataina and its depositional history was dated using 210Pb and tephra chronology. Amongst New Zealand lakes, Okataina may be considered close to a ‘reference’ lake, with 89% native forest and without a significant change in its land use in the past c. 800 years. However, perturbations to the lake during this time may be due to expanding populations of invasive terrestrial mammals, earthquakes, volcanic eruptions and tree felling, which may alter the geochemistry of the soils in the catchment, composition of runoff and, ultimately, the composition of the bottom sediments of the lake. We hypothesised that changes in soil phosphorus geochemistry in the catchment will result in a changing phosphorus species in the lake sediments.
