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 subscales measure mathematics confidence, confidence with technology, attitude to learning mathematics with technology and two aspects of engagement in(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)
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)
Many students confuse decimal numbers, fractions and negative numbers. Data, some of which is new, is provided to support this observation. Interview data also identifies other confusions between number lines and number-line hybrids and between zero and one. These observations are explained by drawing attention to the use of the mirror as a conceptual(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)
We sought to evaluate medical student need for HIV postexposure prophylaxis (PEP) prior to their elective and introduce a 'Pilot PEP Clinic'. We undertook a survey of 388 medical students to assess their elective plans. All were offered an appointment in a clinic, assessed via a protocol and provided a PEP 'starter-pack' prescription if criteria were met. A(More)
1 Abstract Using CAS in the classroom provides many opportunities for improving student learning. However, to take advantage of such a powerful instrument as CAS requires changes to many aspects of the classroom. The different ways in which three pioneering Australian teachers adapted their teaching to use CAS are described. Two of the teachers taught an(More)
Research studies have found that the majority of students up to age 15 seem unable to interpret algebraic letters as generalised numbers or even as specific unknowns. Instead, they ignore the letters, replace them with numerical values, or regard them as shorthand names. The principal explanation given in the literature has been a general link to levels of(More)
