    The main purpose of this paper is to present Slovenian and Finnish prospective chemistry teachers' perceptions of their future profession, especially with regard to their understanding of the role of the triple nature of chemical concepts (macro, submicro and symbolic) and their representations in chemistry learning. A total of 19 prospective teachers (10 Slovenian, 9 Finnish) at master's level in chemical education participated in the research. The prospective teachers' opinions were gathered using an electronic questionnaire comprising six open-ended questions. The study revealed many parallels between Slovenian and Finnish prospective chemistry teachers' perceptions of their future profession and their understanding of the role of the triple nature of chemical concepts, especially particle representations, in chemistry learning. The majority of the prospective teachers from both countries believe that personal characteristics are the most important attribute of a successful chemistry teacher. Thus, they highly value teachers' enthusiasm for teaching and the use of contemporary teaching approaches in chemistry. The prospective teachers displayed an adequate understanding of the role of the triple nature of chemical concepts (i.e., particle representations) in the planning and implementation of a specific chemistry lesson.

    Teachers' role in scaffolding students' problem-solving process is crucial. New technology provides researchers with possibilities to explore this aspect of teaching from the viewpoint of teacher attention. The aim of this mixed-method case study was to investigate the relation between a teacher's scaffolding intentions and his gaze behavior. The data was collected during a mathematics lesson using mobile gaze tracking devices, stationary video cameras, and interview. The results show that the teacher's scaffolding intentions affected his gaze targets significantly and that mobile gaze tracking can provide novel insight to situational processes of teacher-student interaction.
