In our context, being professional means being the effective teacher, which is required to develop continuously throughout the whole career. Teacher professional development, in this article, mainly the issue of teacher professional self-development is discussed. In order for that to be realized, the reflective approach is bring introduced. Here, the reflective approach is primarily based on doing Action Research that includes Rettospective technique, Observation technique, Questionnaires and Interviews and Case Study.展开更多

From the result, a conclusion can be reached that journal writing can provide an opportunity for teachers to write reflectively about their teaching, and teachers differ in the extent to which they can write reflectively.展开更多

Dust fouling is site specific, and the understanding of interactions between different weather and or environmental parameters is crucial for plant profitability. This research intends to provide useful insights on the interaction between the most relevant weather parameters affecting soil accumulation. Results show a significant dependency of dust concentration versus humidity and ambient temperature, as well as a nexus between wind speed and ambient temperature seems to exist. As long as the temperature decreases an increase of humidity and dust concentration occurs. This phenomenon takes place mostly overnight till the first hours of the morning. Therefore, mirror＇s reflectance looks extremely affected by dust accumulation because of high humidity rate during the night and dews of early morning. Further investigations are required to validate the hypothesis that, a more effective cleaning activitie to restore plants＇ reflectivity are to be carried out during the early morning.展开更多
