This study examined technology integration in Natural Sciences teaching and learning in South African township schools. A mixed method approach was adopted as part of an exploratory descriptive survey design. Data was collected through semi-structured interviews, classroom observations as well as administration of open-ended survey questionnaire. The study involved purposively selected grade 9 Natural Sciences teachers and learners as participants. The empirical investigation is underpinned by technological pedagogical content knowledge (TPACK) as the underlying theoretical framework. The participants demonstrated a positive disposition about technology integration in Natural Sciences teaching and learning. In particular, technology integration was perceived to provide opportunities for the enhancement of meaningful Natural Sciences teaching and learning in township schools. Digital resources were largely viewed as essential educational tools that can be deployed to demystify abstract scientific concepts with a view to enhance scientific literacy. Theoretical implications for technology-enhanced teaching and learning are discussed.

Abstract From an international perspective, research in the field of public attitudes towards science and technology has been conducted since the 1970s. A frequently proposed – and empirically supported – theory is that strong interest in and knowledge about science in a society is associated with more favourable attitudes towards science. This positive attitude in turn affects support for public funding of science. However, this research field is not without controversy, and for the South African population many questions remain unanswered. Initial research has not explored the factors that shape attitudes towards science and technology in detail. We re-analysed data from the Human Sciences Research Council to explore the above theory. Interestingly, for the South African population, higher levels of scientific literacy and use of information sources are associated with more promises but also more reservations towards science and technology. This is especially true for relatively young and educated survey respondents. In international comparison, South Africa shows a unique fingerprint to some extent, but also shares characteristics with industrially developing countries of Europe (such as Greece or Portugal). To understand the correlations better, future research should aim to examine the overall picture when investigating the diverse South African population more extensively.

A decade after the introduction of the topic into the South African public school curriculum, the theory of evolution by natural selection is poorly understood among those who teach it, and that flawed understanding is transferred to those attempting to learn it. The curricula, support material and textbooks designed to underpin teaching and learning of evolution are often inaccurate. Deeply held religious views in the country, especially Christianity, remain a stumbling block towards understanding and accepting evolution. The lack of scientific literacy allows for the continuation of Social Darwinism and racial stereotypes and deprives the victims of those ills of the knowledge and mechanisms of thought to counter these ideas. This review explores the relatively sparse but nevertheless well-conducted research into evolution education in South Africa. We conclude that an understanding of human evolution is essential to the country’s growing democracy because it provides a framework within which South Africans can understand and appreciate the diversity and heterogeneous nature of our society.

The overall performances in the Trends in International Mathematics and Science Study (TIMMS) and Progress in International Reading Literacy Study (PIRLS) of South African learners have been dismal to say the least and the Annual National Assessment test results of grade 3, 6 and 9 learners related to general literacy and mathematics have left a lot to be desired. Clearly this suggests that something has to be done to address this. At the same time, South African education is still suffering as a result of the legacy of apartheid and the great majority of schools are lacking basic resources such as libraries, infrastructure and Information and Communication Technology (ICT) resources, including internet connectivity. General learner literacy and ICT literacy development and usage for learning are high on the government’s agenda, as is scientific literacy. However, there seems to be a dearth of ‘how to’ implement ICT related activities to develop reading, talking, listening and writing within a science classroom learning context with special reference to promoting scientific literacy in its fundamental sense. The theoretical and practical outline that follows attempts to assist filling the void related to the above by introducing an ICT based scientific literacy heuristic that is infused by the ICT based ‘Extended Cyberhunt Approach’ of Du Plessis (2010) and Du Plessis and Webb (2011, 2012, in press) and the off-line Scientific Literacy model of Webb and Villanueva (2008); Webb and Mayaba (2010) and Webb (2010). The focus of the heuristic is to develop scientific reading, talking, listening and writing, as well as to establish a different classroom learning space and experience. In addition, it adds emphasis on on-going feedback from the teacher to the learners as well as focusing on reflection and journal writing to inform teacher planning and subsequent interactions in the science classroom. The additional potential of the heuristic is not only that it offers ICT literacy skills development and the development of skills within a curriculum related science context, but also that ICT skills can be developed even without internet connectivity through using Microsoft Word and/or PowerPoint for writing development and presentation or adding Web 2.0 tools such as a Wiki to complement Microsoft Word and/or PowerPoint if connectivity is available. Research suggests that various skills such as planning, searching and researching, presentation, assessment as well as various cognitive skills can be developed when ICT is used as a cognitive tool in a ‘Learning-as-Design’ context, i.e. when learners (students) become the designers and composers of artefacts related to topics that are curriculum based. This paper also then forms the base for an intervention in two primary schools in the Eastern Cape Province in South Africa that has received ICT resources for the first time ever, including internet connectivity, in September 2013. Hence, the anticipated research within these two schools will explore whether this heuristic has the potential to assist with and improve scientific reading, talking, listening and writing, as well as whether this approach improves motivation and interest related to science learning and ICT literacy development, including the potential to develop planning, searching and researching, presentation, assessment as well as various associated cognitive skills. Key words: cognitive tools, heuristic, ICT, PowerPoint, Internet, scientific literacy.

Nudaurelia capensis β virus (NβV) is an RNA virus of the South African Pine Emperor moth, Nudaurelia cytherea capensis (Lepidoptera: Saturniidae). The NβV capsid is a T = 4 icosahedron that contains 60T = 240 subunits of the coat protein (Mr = 61,000). A three-dimensional reconstruction of the NβV capsid was previously computed from visions embedded in negative stain suspended over holes in a carbon film. We have re-examined the three-dimensional structure of NβV, using cryo-microscopy to examine the native, unstained structure of the virion and to provide a initial phasing model for high-resolution x-ray crystallographic studiesNβV was purified and prepared for cryo-microscopy as described. Micrographs were recorded ∼1 - 2 μm underfocus at a magnification of 49,000X with a total electron dose of about 1800 e-/nm2.
