Over the past few years, drones also known as unmanned aerial vehicles (UAV), have been adopted as a part of transportation activities in logistic sector. This paper investigates a new version of traveling salesman problem called as flying sidekick traveling salesman problem(FSTSP) in which trucks and drones serve the customers in coordination with the objective of minimizing the total delivery distance of trucks at the depot after completing the deliveries. Clarke & Wright's savings algorithm is a well-known heuristics approach in literature, which gives better solution for classical vehicle routing problem. In this paper, a hybrid approach based on Clarke & Wright's savings algorithm and genetic algorithm is proposed for solving the new version of travelling salesman problem. In the proposed hybrid algorithm, which is the sequential use of genetic algorithm and Clarke & Wright's savings algorithm, is used for assignment of the truck, drone or both of them to serve the customer. The solution of the genetic algorithm, which is the well-known metaheuristic approach, is enhanced with Clarke & Wright's savings algorithm. The aim of the problem is to minimize the total delivery distance according to the assignment decisions. This is the first hybrid approach in the literature including Clarke & Wright's savings algorithm and genetic algorithm that applies for FSTSP problem. The hypothetical experiments conducted on various instances and results confirm the efficiency of the approach and give some insights on this drone delivery system.

vii and talented students and use of technology subscales 'efficient', professional development subscale 'less efficient', extracurricular activities and math history subscales 'moderate efficient'. According to the MATOZI Scale there is no significant difference between self-efficacy and field qualification regarding on gender, age, experience, graduate education, schools, grade levels, the number of students for each class and colleges. However, there are significant differences in subscales. For instance, there are significant differences between the gender for professional development, a difference between male and female teachers for gifted and talented students and use of technology. There is a significant difference between secondary and high school education for extracurricular activities subscale.According to the results of this research, some recommendations were provided for the researchers and Ministry of Education (MEB).

In this journal, research articles which reflect the survey with the results and translations that can be considered as a high scientific quality, scientific observation and review articles are published.
