ABSTRACT In Namibia, Omusati Region is one of the poorly performing regions in Physical Science Grade 12 national examinations (Omusati Regional Advisory Services (ORAS), 2015). Despite the poor performance, there are few schools in this region which have been ranked among the top six performing schools in the country. These schools are located in the same geographic region with other schools with a poor performance record. Therefore, this study investigated practices that could help improve...
ABSTRACT The current Pennisetum glaucum (L.) R. Br. cultivars in Namibia have overall poor performance and this poses a threat to the nation's food security because this crop is staple for over 70% of the Namibian population. The crop suffers from a range of undesirable production traits such as; susceptibility to diseases, low yield and prolonged reproductive cycle due to lack of genetic diversity. This study was aimed at understanding the genetic diversity of the crop in Namibia by means o...
ABSTRACT Previous studies alluded to the impacts of HIV/AIDS on education in Namibia. While such studies implied that secondary school science education was under the threat of Human Immuno-deficiency Virus/Acquired Immuno-Deficiency Syndrome (HIV/AIDS), there was a paucity of disaggregated and empirical data that spoke to the specific linkages between HIV/AIDS and secondary school science education. Therefore, the purpose of this study was to elucidate the HIV/AIDS impacts, risk factors, an...
ABSTRACT This study investigated the effectiveness of a learner-centred approach in the teaching and learning of acids and bases at two selected secondary schools in Ohangwena region, Namibia. The study employed a quantitative approach and a quasi-experimental nonequivalent (pre-test-post-test) control group research design was used to collect data from two schools for two weeks (one at each school). Within this scope, a total sample of 80 grade 11 learners taking Physical Science Ordinary l...
ABSTRACT In an effort to provide information that can guide prevention strategies, this study determined the risk factors for HIV infection in Namibia and estimated the potential for HIV prevention. The study adopted a cross sectional research design with a sample of 14296 VCT clients from Oshana, Khomas and Kavango regions of Namibia for the period of 2009 to 2012. A multivariate logistic regression analysis was used to identify risk factors for HIV infection among VCT clients. For risk fac...
Abstract As a result of the ever increasing population growth, the demand on food is expected to rise significantly. In order to meet this increase in food demand, alternatives (PGPR and biocontrol bacteria) to environmentally damaging chemical augmenters can be utilized for the production of agricultural crops. This study was conducted to isolate and screen rhizospheric bacteria from grasses along the Kavango River for plant growth promoting and biocontrol abilities. Once validated, bacteri...
ABSTRACT Teaching and learning Natural Science for conceptual understanding requires appropriate and effective teaching approaches and inquiry-based learning activities. The problem of teaching and learning Natural Science for deeper understanding is global and Namibia is not an exception. The Ministry of Education, Arts and Culture’s reports on the National Standardised Achievement Tests (SATs) results of Grade 7 Natural Science showed that learners scored under basic achievement category...

ABSTRACT This research work investigated the effects of laboratory exercises on science secondary school students’ performance in chemistry, in Kaduna State, Nigeria. In most of the literature reviewed, the final outcome favoured laboratory exercises. Quasi experimental and descriptive survey research were employed in this study. In quasi experimental design the researcher selected six (6) schools out of 372 science schools across the state. Similarly, 31 schools were selected for survey r...
ABSTRACT The aim of this study was to determine the effect of Angela Reilly Harden linear algebra games as a means of consolidating the learning of linear algebra at SHS form one of Armed Forces and Osei Kyeretwie Senior High School. One hundred and twenty first year students were randomly selected for the study. Sixty students were selected for the control and sixty students for the experimental groups. For both groups, a test was applied as a pretest before the instruction. Both groups we...
