The great circle is of special importance as the shortest distance between two points in navigation. Navigating officers must always be able to calculate the path of the great circle and the turning points on that path. One of the drawbacks of calculations in the path of the great circle is the large volume of calculations and the uncertainty of the correct result. In this research, using the method of composite triangles, the path of the great circle is solved and two general methods for calculating the rotation points of the great circle, which include a) calculating the rotation point with equal longitude difference and b) calculating the rotation point with distance difference equal is used. Next, using the method of equal longitude difference in calculating the points of rotation, a fast and reliable relationship has been developed to calculate the points of rotation. The premise of the developed method is that the point of rotation is always equal to the difference in longitude between the origin and destination. The developed method can calculate the width of the turning point only by calculating 5 sentences from Norris book.

The issue of improving the quality of learning is a constant issue in any educational environment. In the training of seafarers, this issue is of particular importance due to international maritime regulations. The quality of learning that is influenced by a wide range of factors: from the labor market and educational policy to the motivation, effort and individual characteristics of students. The motivations for choosing a seafaring job and learning approaches are individual characteristics.The quality of learning is influenced by students' approaches to learning, a deep approach to learning is related to a higher quality of learning and a superficial approach to a lower quality of learning, on the other hand, learning approaches can also be influenced by job choice motivations that affect the entire career process. and both phenomena are important in improving the quality of learning.The purpose of the research is to evaluate the relationship between the motivation of choosing a seafaring job on students' learning and providing solutions to improve the quality of seafarers' education. The study of sources and documents was analyzed and then quantitative analysis was used to verify qualitative information.The statistical population consists of 100 ship navigation students who were selected through available sampling. The results show that the relationship between deep approach and emotional attractiveness of students, Spearman coefficient = 0.316, talent and personal interest, Spearman coefficient = 313. 0 and the use of the professional benefits of the seafaring job shows the Spearman coefficient = 0.186.That is, if a student chooses a job with the mentioned motives, his studies and education will be of higher quality. And in deciding to become a sailor with a superficial approach and choosing a job randomly or under the influence of relatives, the studies and learning of students will be of lower quality.
