This research focuses on how teachers’ self-efficacy changes as a result of a project consultancy training and their views on project-based learning. The study group of the research consists of 47 teachers working in Ministry of National Education who participated in “2237 coded Project Consultancy Trainer Training” program organized in 2019 in cooperation with The Scientific and Technological Research Council of Turkey (TUBITAK) and Ministry of Education. In this research, mixed method was used in which qualitative and quantitative data were used together. In the quantitative stage of the research a semi-experimental design without a control group; in the qualitative stage, a case study was adopted. As the data collection tool, “Self-efficacy scale related to project based teaching” developed by Mutlu and Yildiz Fidan (2018) and “Teacher view form related to project based teaching” developed by the researchers were used. As a result of the study, it was concluded that there was a statistically significant increase between the pre-test and post-test scores. In addition, it was determined that there was no significant difference according to the variables of gender, branch and making project status. From the teachers' views on project-based teaching, the most difficult stage of the project was “finding a project subject”; and it was understood that “writing reports” was the stage that they thought they could easily do while they were doing the project. However, it was found that the views of teachers such as “my deficiencies were completed” and “my self-confidence / motivation increased” were formed as a result of the training.

The purpose of this research is to identify the effect of the activities on student’s opinion about the science nature which is prepared with the explicit reflective teaching approach and integrated with 9th grade biology lesson syllabus by the teachers who gets distance education about teaching the nature of science. For that purpose, in this research, quasi experimental design with pretest and posttest control group has been used. For that purpose, in this research, quasi experimental design with pretest and posttest control group has been used. 2 teachers and 114 students in an Anatolian High School in Meram/Konya have participated in this research in the whole 2014-2015 academic year. In this project, BDHGA Form C (a survey on the ideas about nature of the science), and YYG (semi-structured interview) and Rubic are used as data collecting tools. The qualitative data of the research has been analyzed with content analysis, descriptive analysis and document review. The quantitative data has been analyzed with the SPSS 17 software using ANOVA and T-test for related samples. According to the both quantitative and qualitative data obtained from the research, the experiment class, in which the teacher educated in distant about nature of science and has taught the topic in process based way to the students, is observed to be more developed in this topic than the other class. Also it is seen that only being educated about science nature of the teachers is not adequate. However, the usage of the explicit reflective activities integrated into syllabus has contributed to the perception of the students about the nature of science topic.
