Which e-learning technology is right for me?

The range of technologies available to support teaching and learning in higher education continues to grow exponentially. There is a growing expectation for educators to be well informed and familiar with the many suitable technologies and systems that are available to be used for delivering courses online, and to complement classroom (face-to-face) education. Detailed evidence of the perceptions and applications of the use of e-technologies is needed to inform not only teaching practice, but also policy development. These e-technologies need to be matched to pedagogical styles in order for online teaching and learning to be successful. Based on 33 semi-structured interviews, this paper presents a study of staff experiences of e-technologies, using Chickering and Gamson's 'Seven Principles of Good Practice' to provide educators with information about the most appropriate e-technology to support their pedagogical aims.

Moving right along: what powers do police have to 'move-on' protestors?

When police removed a young woman’s “tent dress” this week at the Occupy Melbourne encampment, it was yet another controversial interaction between protesters and authorities.

Being the right kind of male teacher : the disciplining of John

In a context where the lack of male teachers is constructed as a worrying concern for many Western education systems, men who make the decision to become teachers, particularly in early childhood and primary education, are often adulated. However, alongside this adulation sits an expectation to be a ‘real man’. This paper tells the story of John, a male primary school teacher who left the teaching profession after one year as a result of incommensurable differences between the expectations held of him as a male teacher and his identity as a primary school teacher. While not an attempt to position John as a victim, this paper suggests that expectations of male teachers, such as to be effective disciplinarians, have normalising effects on men within the teaching profession that, in this case, led to a rejection of teaching as a career path. We contend that the image of the ‘imagined male teacher’ that underpins both current calls for more male teachers and John’s departure from schooling is likely to have a negative impact upon all students (boys and girls) and also denigrates the work of female teachers.

Localisation of an object in motion in 3D space via angle only measurements

In this paper, we discuss an approach to localisation of a moving object in 3D space. The method used to track this object is angle only measurements obtained via radar elements strategically placed within the X, Y and Z planes. In addition, computer simulations are conducted to verify the theoretical assertions presented with respect to the application employing an Extended Kalman Filter.

Why is the tetrahedral bond angle 109°? The tetrahedron-in-a-cube

The common question of why the tetrahedral angle is 109.471° can be answered using a tetrahedron-in-a-cube, along with some Year 10 level mathematics. The tetrahedron-in-a-cube can also be used to demonstrate the non-polarity of tetrahedral molecules, the relationship between different types of lattice structures, and to demonstrate that inductive reasoning does not always provide the correct answer.

Fortification. Folic acid and spina bifida. Is it safe? Is it wise? Is it right?

Food fortification takes many forms. The example discussed here is unusual, because in many countries now it is required by law: the fortification of flour with the B vitamin folic acid, or MFFFA for short. Voluntary fortification of various food products was first used to help prevent and control child and maternal anaemia associated with folate deficiency (1). In the mid-1990s, policy-makers in various countries began considering using mandatory fortification under a novel policy paradigm, that fortification was needed to increase the folic acid intake and protect the health status of people who had a special requirement for this nutrient, irrespective of the folate status of the population as a whole.
