摘要:The motivation for career choice motivation of student-teachers is a well-studied topic with a representative theoretical basis in teacher education research that has a long-standing tradition in the international research landscape. However, in understanding the pressing questions of why young people choose to become teachers, only a few longitudinal and comparative studies have been carried out that focus on the development of motivation for choosing a teaching career. This longitudinal study reports on the effects of time within initial teacher education and how it influences student-teacher attitudes and motives about the teaching profession. This article is a product of a larger study that aims at addressing the existing literature gap by examining student-teacher change in attitudes of becoming teachers in Austria and Kosovo starting from initial teacher education, during early stages of their teaching career as novice teachers, and to more advanced stages of their teaching career. This is a panel study located within a longitudinal design. In this study, a questionnaire and student-teacher reflection texts were used as instruments. Data were collected in three phases during which 673 student-teachers participated in face-to-face administered questionnaire as follows: 341 (phase 1), 185 (phase 2), and 147 (phase 3), as well as 19 student-teacher reflections. Questionnaire data were analysed using the general linear model (GLM) with repeated measures test, whereas the reflection text data were analysed using thematic analysis. The findings in this longitudinal study provide evidence that student-teacher attitudes and motives for becoming teachers can change over time during the initial teacher education in Austria and Kosovo, and they can be influenced by in-school experiences during teaching practice. The study concludes that motives for choosing a teaching career are primarily intrinsic, are not time-stable, and change over the course of studies. The study findings have clear implications for initial teacher education programs in addressing changes in student-teachers’ attitudes of becoming teachers. The insights gained from the findings of this study lead to recommendations that initial teacher education programs should strengthen teaching practice to better manage the preparation of students and teachers and their entry into the teaching profession.
