This paper reports on the use of out-of-school everyday contexts in Namibian science classrooms. This use is portrayed against the backdrop of an explicit educational philosophy of learner-centred teaching. Data were collected through audio-taped teacher-learner interactions and non-participant field notes in 29 junior and senior science classes taught by 12 teachers in six schools. An existing typology was applied to classify episodes of use of everyday contexts and identify teachers' pedagogic strategies for their use. The results show that more everyday contexts are used in junior secondary than in senior secondary classes, that only a limited range of types of everyday contexts are used at both levels, and that their use often follows theoretical exposition or teacher questioning. These findings are related to three interpretations of learnercentred teaching. Recommendations for a fuller implementation of learner-centred teaching are made.
Incidences of prescnbed textbook usage in science classrooms in 1Vamzbia have been analysed using an approach adapted from linguistic analysis. Aspects of pedagogic purpose, text genre, and the social interaciions between teachers and learners were used to characterise teacher and Ieamer engagement with textbooks, and thus caregon' se their usage in relatioN to a national policy of learner-centred edu(anon.

Local knowledge about natural resources that may be of use to communities, including medicinal plants, is becoming increasingly important globally. This knowledge is important for the participation of indigenous peoples in the conservation and maintenance of indigenous forests (Gazzaneo, de Lucena, & de Albuquerque, 2005) in addition to the frequent use of these resources in the treatment of common ailments and diseases.Knowledge about the use of local fauna and flora, nowadays, is minimal. To ensure the preservation of indigenous knowledge, this state of affairs needs to be rectified. In fact, Teklehaymanot, Giday, Medhin and Mekonnen (2007, p. 272) note that 'traditional knowledge is rapidly eroding', hence, there is real danger that if something is not urgently done, this knowledge might be lost for good. This is due to the fact that often indigenous knowledge is passed on from older to younger generations orally, and is not documented. According to Kambizi and Afolayan (2006), it is essential to make an effort to avoid the loss of this important knowledge in order to conserve medicinal plants, especially in rural communities. There is an increasing advocacy for the integration of indigenous knowledge into mainstream science curricula.School can play an important role in ensuring this knowledge is not lost. The school is thus seen as a conduit through which this knowledge could be passed from one generation to the next. One way of doing this is to integrate indigenous
This paper presents findings on a study that was conducted at two selected secondary schools in Ohangwena educational region in Namibia. The study used a quantitative approach to investigate if using learner-centred approach improves learners' understanding of acids and bases. With a sample of 80 grade 11 learners taking Physical Science Ordinary level, a quasi-experimental design was used to collect data from two schools for two weeks (one week at each school). The Pre-test, post-test scores from the control group consisting of 40 learners from school A and an experimental group of 40 learners from school B were used to establish the cause and effect relationship between the use of Learner-Centred Approach (LCA) and learners' understanding of acids and bases based on their performance in the tests were given. Descriptive statistics was used to analyse the quantitative data from the tests cores and a t-test analysis was conducted for both groups. The study results indicated that the experimental group performed better than the control group. It also emerged that using various learner-centred activities attracted learners' interests in learning and understanding acids and bases. It is therefore concluded that learner-centred approaches improved high school learners' understanding of the topic acids and bases. The study recommends that Physical Science teachers should make the teaching and learning of acids and bases more practical-based by using learner-centred approaches.
The training programs, irrespective of their scopes and time frames, aim to enrich the skills, knowledge level and attitude of participants so that they eventually enhance organizational performance. The training institution investigated in this study did not have a training evaluation policy at its inception. Hence, the aim of this paper is to report on the lecturers' views on the effectiveness of in-service training at one of the public sector organizations in Namibia. The study adopted a quantitative approach and a total of 27 (11 males and 16 females) academic staff participated in it. The results indicate that the majority of respondents are of the view that the institution does not conduct training need assessments. They also expressed that the in-service training programs provided by the institution do not empower them to become better teachers. It is thus recommended that the institution provides in-service training programs that specifically improve lecturers' pedagogical skills in this regard.Keywords: lecturers' perceptions, in-service training programs, effectiveness of training, public sector organizations, Namibia ResumenLos programas de formación, independientemente de sus alcances y plazos, tienen por objeto enriquecer las habilidades, el nivel de conocimiento y la actitud de los participantes para que eventualmente mejoren su desempeño profesional. La institución de formación investigada en este estudio no tenía una política de evaluación de formación en su inicio. Por lo tanto, el objetivo de este documento es informar sobre las opiniones del profesorado sobre la efectividad de la formación en servicio en una de las organizaciones del sector público de Namibia. El estudio adoptó un enfoque cuantitativo en un total de 27 personas (11 hombres y 16 mujeres) del personal académico participante. Los resultados indican que la mayoría de los encuestados opinan que la institución no realiza evaluaciones sobre las necesidades de formación. También expresaron que los programas de formación que ofrece la institución no les permiten ser mejores profesores. Así pues, se recomienda que la institución proporcione programas de capacitación que mejoren específicamente las habilidades pedagógicas del profesorado en este sentido.Palabras clave: percepción docente, formación continua del profesorado, eficacia de la formación, organizaciones del sector público, Namibia 158 Pieters & Kapenda -Lecturers' perceptions of training programs he training programs, irrespective of their scopes and time frames, aim to enrich the skills, knowledge level and attitude of participants so that they eventually enhance organizational performance. The extent to which this enhancement could be realized is the measure of the effectiveness of any training program (Otero, 1997). The training institution investigated in this study did not have a training evaluation policy and the evaluation of staff performance was based on the following outcomes: successful students' intake and registration, submission of student attendance rec...
