Interview
Semi-structured interviews were used in this research; the author used neither free conversations nor
highly structured questionnaires (Kvale, 1996). As such, semi-structured interviews have the ability to
investigate defined topics and to ensure that the interview provides results while also affording the respondent
with freedom of expression to ensure that all topics are addressed (Kvale, 1996). In this study, science teachers
were asked to give interviews to thoroughly explore their opinions of the new science curriculum and the
challenges and difficulties they face in teaching the new curriculum. A tape recorder was used during the
interviews, which lasted for 30 to 60 minutes. After each interview, the author summarized the answers given
and asked the interviewees to confirm whether this summary and interpretation reflected what they meant.
