ENGLISH ABSTRACT: This thesis explores the use of educational technologies in grades 10 to 12 life sciences classrooms at a local high school. I argue that the application of educational technologies in science classrooms has the potential to engender critical teaching and learning, and to contribute to professional development.
By reflecting on my own professional development as a science teacher over the past three years (2008-2010), I show that the use of educational technologies cultivates moments of critical pedagogy that link strongly with reflective teaching, critical thinking and transformative learning. Drawing on two intertwined narratives, I show how educational technologies can enhance reflective teaching whereby, firstly, teachers can take seriously theories and expertise in their practices; secondly, organise their classrooms so as to facilitate critical learning; and, thirdly, take up broader institutional and social issues.
In addition, I show that the use of educational technologies opens up pedagogical spaces for critical thinking and transformative learning – that is, whereby learners learn creatively, actively, engagingly and reflecting on their own practices.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die gebruik van onderwystegnologie in grade 10 tot 12 lewenswetenskapklaskamers by ʼn plaaslike hoërskool. Ek argumenteer dat die toepassing van onderwystegnologie in wetenskapklaskamers die potensiaal het om kritiese onderrig en leer teweeg te bring, en ʼn bydrae tot professionele ontwikkeling te maak.
Deur te reflekteer op my eie professionele ontwikkeling as ʼn wetenskaponderwyser oor die afgelope drie jaar (2008-2010), dui ek aan hoedat die gebruik van onderwystegnologie krities pedagogiese oomblikke kultiveer wat sterk aanklank vind by reflektiewe onderrig, kritiese denke en transformatiewe leer. Met betrekking tot twee narratiewe dui ek aan hoedat onderwystegnologie reflektiewe onderrig kan bevorder deurdat, eerstens, onderwysers teorieë en kundighede in hulle gebruike ernstig opneem; tweedens, klaskamers organiseer om kritiese leer te fasiliteer; en derdens, breër institusionele en sosiale kwessies aanspreek.
Daarenbowe dui ek aan hoedat onderwystegnologie ook pedagogiese ruimtes vir kritiese denke en transformatiewe leer bied – dit is, waarby leerders kreatief, aktief en betrokke is, en op hulle eie praktyke reflekteer.
