Teaching is a sacred profession performed by self-sacrificing individuals with high responsibilities who are aware of their roles, have undertaken the task of raising future generations, make easier individuals’ process of becoming citizen in a way to ensure the peace and welfare of the communities, and allow them to learn knowledge, skills, attitudes and behaviors. By Ataturk’s saying, "Teachers are the most devoted and respectable factors of human society all over the world". In hadiths, the sanctity of teaching is expressed as, "Only those two people are admired enviously: The person who uses up and consumes the goods bestowed by Allah on him in the right way, and the person who properly rules over by the wisdom to him by Allah and who also teaches it to others.” From early childhood to puberty, the person studying in public institutions establishes a spiritual association with his/her teacher. The psychical aspect of teaching is also quite predominant. The role of teaching is sometimes mixed up with the roles of mother, father, sister and brother. There are many students who keep fresh their relationships with teachers for many years although their education and training activities do not continue. Based on these, the starting point of the study is about which characteristics the teacher must have to become an ideal teacher. This study was carried out to determine the characteristics of an ideal teacher in line with the opinions of the participants of the faculty of education and pedagogical training program in a University in Istanbul. The research was carried out in the screening model. The research data were collected through semi-structured interview technique to find out student opinions in a clearer way. The study group of the research was established in accordance with the voluntary basis from among the students from the psychological counseling and guidance department, Turkish teaching department, gifted children teaching department and English teaching department and the students who are enrolled in the pedagogical training certificate program in a University, in Istanbul, in the 2015-2016 academic year. Face to face interviews were conducted with each participant in the researcher's working office for half an hour on an average. At the beginning of the interview, students were asked about their genders and the graduated university, department and faculty. Within the context of the interview, the question of "what are the characteristics of an ideal teacher for you" was posed to participants. The personal and professional characteristics that an ideal teacher should have were determined according to the opinions of teacher candidates. The discussion section was structured by the research findings in the literature, and the study was finalized with suggestions.

Teachers’ use of everyday cognitive heuristics can lead to biases in information processing and, thus, to unfair assessments of student characteristics. This problem can be addressed by a core aspect of research-based learning, i.e., by making use of principles and methods of empirical research in order to systematically collect information. However, pre-service teachers’ attitude towards the use of empirical research methods is usually rather low. To foster their attitudes, a total of 444 student teachers were confronted with their own biased perception during a methodology course. Biased perception was triggered by a halo effect inducing experiment. In a subsequent semester, n = 113 of these students participated in an online survey. They answered questions about their cognitive activity and affective reaction following the presentation of the results of the experiment. Moreover, they reported about perceived attitude changes towards systematic thinking and research methods. The results demonstrate the successful implementation of the halo effect, which affected the students cognitively and emotionally. Structural equation modelling showed, that attitude change was dependent on both cognitive and affective reactions. The findings indicate that the halo effect is not only easy to implement in university courses but also appears to have substantial impact on students’ attitudes towards research-based learning.
