Currently, teacher education colleges in Tanzania are being equipped with computers to prepare teachers who can integrate technology in teaching. Despite these efforts, teachers are not embracing the use of technology in their teaching. This study adopted Technological Pedagogical Content Knowledge (TPACK) as a framework for describing the knowledge and skills that pre-service teachers need to develop in order to effectively integrate technology in science and mathematics teaching. Pre-service teachers (N=22) participated in microteaching, hands-on training, collaborative lesson design in design teams, and reflection with peers. Preand post-assessment results of the pre-service teachers' perceived knowledge and skills of integrating technology in teaching, showed significant changes in technology-related components of TPACK. We conclude that opportunities for pre-service teachers to participate in professional development programs that involve lesson design, teaching, evaluation and redesign, can be effective for the development of the knowledge and skills of integrating technology in science and mathematics teaching.
IntroductionTanzania experiences, just like many developed and developing countries, a challenge in relation to students' participation and performance in science and mathematics subjects at secondary school education. A report by the Mathematical Association of Tanzania These failures have been attributed to, amongst other factors, the absence of competent teachers, lack of science teaching and learning resources as well as shortage of science and mathematics teachers in most schools (URT, 2008).Since the 1990s the government of Tanzania has taken several initiatives to address the problem of massive failures in science and mathematics subjects in the country. Several projects were established in collaboration with international organisations to enhance science and mathematics teaching approaches, to prepare new teaching resources including books, and training of more science and mathematics teachers (O-saki, 2007). One of the projects was the Science Education in Secondary Schools (SESS) a project funded by the German GTZ in 1997, and based in the Ministry of Education and Culture in Tanzania, aiming at improving teaching and learning in science and mathematics for girls and boys in secondary schools (O-level) in Tanzania. Another project was the Teacher Education in Mathematics and Science (TEAMS) from 1996 to 2004 which was funded by the Dutch government to review the undergraduate science teacher education programs at the University of Dar es Salaam, by conducting research, training postgraduate students and developing in-service Australasian Journal of Educational Technology, 2015, 31(4).

Despite these initiatives to overcome the massive failure of students in science and mathematics, the situation has remained poor (O-saki, 2007).Further efforts to enhance science and mathematics teaching and learning outcomes focused on ...
