The Mathematics and Technology Attitudes Scale (MTAS) is a simple scale for middle secondary years students that monitors five affective variables relevant to learning mathematics with technology. The sub-scales measure mathematics confidence, confidence with technology, attitude to learning mathematics with technology and two aspects of engagement in(More)
This paper reports on the effectiveness of an intervention designed to improve nursing students' conceptual understanding of decimal numbers. Results of recent intervention studies have indicated some success at improving nursing students' numeracy through practice in applying procedural rules for calculation and working in real or simulated practical(More)
Most successful Bayesian network (BN) ap­ plications to date have been built through knowledge elicitation from experts. This is difficult and time consuming, which has lead to recent interest in automated methods for learning BNs from data. We present a case study in the construction of a BN in an intel­ ligent tutoring application, specifically dec­ imal(More)
Before the 1960s, introductory trigonometry was taught in Victorian schools using the ratio method, where trigonometric functions are defined as ratios of sides of right angled triangles. With the advent of "new maths", the unit circle method was introduced. This study explored differences between the two methods for teaching introductory trigonometry.(More)
The structure of certain word-problems can be perceived in different ways, depending on the grammatical form of presentation of the problem and the student's expectation of how it will be solved. The results of our study involving 268 school students aged 14-16 show that, for a certain class of problems, different problem presentations promote the(More)
Teaching the inner workings of ciphers such as Advanced Encryption Standard (AES) or Data Encryption Standard (DES) can be improved with the use of visualisation tools. It is proposed that the use of Empirical Modelling techniques to construct models of these algorithms will assist in understanding how they work. This is because the interactive nature of EM(More)
This paper reports an evaluation of an adaptive computer system designed to diagnose and improve students' conceptions of decimal numbers. The system provides some simple computer games and a test for students aged about 10 to 14. A Bayesian net is used for diagnosis, prediction and sensitivity analysis. Field testing with 25 students who had substantial(More)
The purpose of this paper is to demonstrate the use of the statistics of relative risk and odds ratios in mathematics education. These statistics are widely used in other fields (especially medical research) and offer a useful but currently under-utilised alternative for education. The demonstration uses data from a longitudinal study of students'(More)
