Abstract:
The purpose for this study was to explore Grade 11-12 teachers� use of instructional videos in Natural Science subjects at Ponhofi Secondary School in Namibia. To explore the attitudes, perceptions and experience 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 reveal 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 show that the majority 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 reveal 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. Since the purpose of the study was to explore the teachers� attitudes, perceptions, beliefs and experience towards the use of instructional videos in teaching Natural Science subjects at secondary school level, the study could help Curriculum Development Units and Instructional Designers at the National Institute for Education Development (NIED) in Namibia to make necessary changes/ amendments in the Natural Science curriculum to improve the integration of instructional video and other educational technologies in the teaching/learning materials and ultimately the curriculum.
