    (International Journal of Arts and Social Science, 2023) Nghuumbwa, Malakia; Shaimemanya, Cornelia Ndahambelela S.; Shihomeka, Sadrag P.; Kapolo, Paulus
    This study explored Grade 11-12 teachers’ use of instructional videos in Natural Science subjects at Ponhofi Secondary School in Namibia. To explore the attitudes, perceptions and experiences of teachers’ use of instructional videos, 8 semi-structured interviews (pre and post) were conducted. The pre-semi structured interviews were about the teachers’ attitudes, perceptions and experiences and were held with individual teachers before the teaching intervention using instructional videos. After the intervention, the post semi-structured interviews were conducted with the same individual teachers to assess their attitudes, perceptions and experiences after the use of instructional videos. The findings revealed that most of the teachers perceive instructional videos as powerful tools to teach Natural Science subjects and good for the learners’ subject mastery. The results further showed that most of the teachers lack self-confidence and have a high level of technophobia. It also emerged that there are a lot of barriers that affect teachers’ ability to use instructional videos such as technology resources, technology support, knowledge and skills and these barriers negatively affect the use of technology in schools and prevent teachers from becoming frequent technology-users. Finally, the findings revealed that, most of the teachers use free downloadable videos from various websites such as Eureka, Make Me Genius, Smart Learning for All and YouTube. The study concluded that teachers should adopt the culture of using instructional videos in their lessons to make their lessons informative, interesting, and resourceful and enhance understanding, and knowledge retention

    (IGI Global, 2019) Shaimemanya, Cornelia Ndahambelela S.; Shihomeka, Sadrag P.
    The purpose of the chapter was to examine the leadership practices of school principals whose agenda is to green the schools in an effort to achieve sustainability in Namibia and build environmental knowledge of the Namibian secondary school learners. The study was qualitative and used a purposive sampling of eight teachers and environmental clubs at three selected schools in the Khomas education region. The results revealed that these teachers hold a non-remunerative position of coordinating for the Environmental Club as an extra-mural responsibility and they were doing it because of their natural love for the environment and interest in educating the young and future generations about sustainability/sustainable living. The chapter recommends that the school management should provide maximum support to the practicing and responsible green school project coordinators at various schools to motivate and guide them when necessary
