Contemporary research models are becoming increasingly transdisciplinary (TD), multilevel, community-connected, and bent on expediting the movement of research to impact. This requires not only fresh thinking about the science of social work but an educational architecture that fosters both cross-disciplinary understanding of complex underlying…

Social work education grounded in social work practice has been recently challenged to examine the role of science in its history, core constructs and domains, philosophical underpinnings, and graduate curriculum. Doctoral education has been added to the scrutiny at the recent Science in Social Work Roundtable in Doctoral Education. Based on Lev…

We investigate the current bandwidth selection methods in kernel equating and propose a method based on Silverman's rule of thumb for selecting the bandwidth parameters. In kernel equating, the bandwidth parameters have previously been obtained by minimizing a penalty function. This minimization process has been criticized by practitioners…

The South African science curriculum advocates an inquiry-based approach to practical work. Inquiry is a complex and multifaceted activity involving both cognitive and physical activity; thus, paper-and-pencil items do not provide the authentic context for this assessment. This study investigates the construct validity of inquiry-related questions…

The National Senior Certificate or "matric" examination is a key point of access to further education and the labour market in South Africa. Since 1999, matric candidates whose first language is not Afrikaans or English and are, therefore, forced to write in a second or third language have received a compensation of five per cent of…

In this case study, Mathematical Literacy teachers were interviewed and observed in the classroom in order to provide insight into the way this subject, relatively new in South African schools, is handled. The focus of this research was the instructional practice of these teachers specifically in terms of their mathematical knowledge regarding the…

In South Africa, the Department of Basic Education and Training (DBE) is responsible for primary and secondary education (Grades R-12). In an effort to improve educational standards in literacy, numeracy and mathematics, especially in the Foundation Phase (FP) levels of education, the DBE has developed several initiatives and campaigns. To monitor…

This paper details the construction of a weather vane for the measurement of wind direction in field situations. The purpose of its construction was to analyse how wind direction affected the attractiveness of an insect pheromone in a dynamic outdoor environment, where wind could be a significant contributor to odour movement. The apparatus…

Students' misconceptions concerning colour phenomena and the apparent complexity of the underlying concepts--due to the different domains of knowledge involved--make its teaching very difficult. We have developed and tested a teaching device, the addition table of colours (ATC), that encompasses additive and subtractive mixtures in a single…

This paper describes an interactive tool for analysis of data from the ATLAS experiment taking place at the world's highest energy particle collider at CERN. The tool, called HYPATIA/applet, enables students of various levels to become acquainted with particle physics and look for discoveries in a similar way to that of real research.

This paper is concerned with the role of standards and standard setting in shaping the expansion of post school education in highly unequal society. It draws on an account of the debates and policies on standards in the UK from the 1980's to today and the wider lessons that can be learned from them. It argues that relying on any type of…

The history of science remembers more than just formal facts about scientific discoveries. These side stories are often inspiring. One of them, the story of an unfulfilled death wish of Jacob Bernoulli regarding spirals, inspired us to look around ourselves. And we saw natural spirals around us, which led to the creation of a Hooke's…

This paper describes an intervention programme that was originally intended to support transition to English as language of learning and teaching (LoLT) in Grade 4 in a township school, using a pre- and post-test design. Because the pre-tests revealed very poor literacy levels in both Zulu home language and English, the intervention programme was…

Three themes are central to preparing doctoral students for the professoriate: identity formation, scientific integration, and intellectual communities. In this article, we argue that these three themes are not separate pillars but interlocking circles. Our main thesis is that (1) social work must develop into a distinct integrative scientific…

This research proposed a situational learning system to help elementary school students practice and improve their English as a foreign language (EFL) writing skills. Students carried out assigned writing tasks using the support of mobile devices in situations deemed to be familiar to the students, such as on the school playground, within…
