Combining theory and practice (Neuweg, 2018) is a core characteristic of teacher education in Switzerland. Not only courses at university and pre-service-teaching at school aim to combining knowledge, experience and findings, but specific courses also align on such goals (Keller-Schneider, 2018). Good qualified courses are important pre-conditions for learning, but they cannot guarantee for a learning output. Individual teacher students’ reflection and commitment (Korthagen/Vasalos, 2008) are crucial as well. A specific course was created, activating teacher students’ reflections on theory and practice on action and in action (Schön, 1983). Focusing on learning goals on different levels (Anderson/Krathwohl, 2001), student teachers acquire knowledge and work on demanding tasks, based on a constructivist approach on teaching and learning. Student teachers are obliged to perform their acquired knowledge and competence in analyzing their own case study. This course is framed by a reflection and evaluation tool. In a survey (pre-post-design), student teachers think on their knowledge and beliefs, reflect their learning, their use of different elements of the course and their commitment and individual characteristics. The research study investigates the interplay between specific elements and the perceived quality of the course, students’ use of learning opportunities and their individual motives, beliefs and goals on the learning output. The presentation is focused on the following questions: 1) How does the perceived quality of the course shape the learning output of the student teachers? 2) How does student teachers’ use of the learning opportunity and their learning strategies shape the learning output? How do they mediate the quality of the course? 3) In which ways do individual characteristics of student teachers effect learning output and how do they mediate the effects of the quality of the course? Data were collected through an online survey in a pre-post-test (n= 750). Student teachers were asked about their knowledge, their use of the learning opportunities and their learning strategies as well as about their motives, beliefs and their interest in working on the goals of the course. Data were analyzed by regression analyzes and structural equation modeling. Results show that the use of the learning opportunities and learning strategies, student teachers’ commitment and motives and their beliefs on teaching and learning are significant for the learning output. The results will be discussed on their significance for specific approaches in teacher education.
