The National Libary - The Libary of Vietnam National Institute of Educational Sciences PREAMBLE The reason for topic selection The Resolution of "Vietnam Sea Strategy to 2020" was adopted in February 2007 at the 4th Central Executive Committee Meeting (Session X), this is Vietnam's first strategy on the sea It’s also a guideline to guide the development of Vietnam's maritime economy in the current market economy Along with the implementation of the commitments when joining the World Trade Organization, the effective implementation of the maritime industry, the marine economic sectors associated with the construction and development of "Vietnam Marine Brand " The orientation of the Sea Strategy is extremely important to bring our country "Quickly going to the sea, becoming a strong nation on the sea and enriching the sea”, in the Resolution on "Vietnam Sea Strategy to 2020” was required Evaluating after more than 10 years of implementing and implementing the Resolution on "Vietnam Sea Strategy to 2020", the 8th Central Conference of the XII Session (October 2018) summarized the positive results for priority areas Firstly, to develop is oil and gas exploitation and processing; exploitation and processing of marine products; developing maritime economy; developing sea tourism and resorts; strengthen the construction of economic zones and industrial parks In particular, the maritime economy has developed significantly, the output value of the shipping industry, port services and shipbuilding has continuously increased, with a growth rate in the period of 2007-2010 is 22% / year, the period 2011 - 2015 is 13% / year However, the overall contribution of the maritime economy to the national GDP is still very small and tends to decrease, with 1.05% in 2010, 0.98% in 2015 and 0.97% in 2017 Analyzing the results and limitations, the 8th Conference also stated that the implementation of the Resolution still has many limitations, weaknesses, difficulties and challenges in the sustainable development of the marine economy Development of marine economy has not been in harmony with social development and environmental protection, in which the implementation of the policy of developing some key marine economic industries has not met the requirements set forth Science and technology, basic investigation, and development of marine human resources have not yet become a key factor in sustainable development of marine economy The limitations and weaknesses mentioned above have an objective reason, but the subjective reasons are the main reasons In particular, according to the assessment of the General Department of Sea and Islands of Vietnam, a major subjective factor and the most influential to the reality is the development of marine human resources Vietnam's human resources are inadequate in quantity and weak in quality, the structure of human resources is still imbalanced, and the management team is weak in professional and professional skills Human resources for innovative research are few and low in quality, so the achievements in marine science and technology for marine related activities have not met the requirements The main reason is that the investment in developing human resources is still inadequate; lecturers are still weak and weak; training institutions, research institutes, equipment and facilities, qualifications of personnel in service of human resource training and development are both lacking and weak while international cooperation in the field of training Creation of the sea has not been strongly promoted Overcoming these difficulties, in the past 10 years, the development of marine human resources in our country has been concerned and invested effectively The Government has assigned the Ministry of Education and Training to assume the prime responsibility for, and coordinate with ministries, branches and localities in, conducting review of human resource development projects, with a focus on developing marine human resources through training training (undergraduate and postgraduate), vocational training, building training facilities and human resource training programs for marine management and exploitation The focus on developing human resources through training at universities is shown by the career support process for employees as soon as they are sitting on the school chair Training in schools is conducted through educational activities, in which teaching activities play a major role And so, teaching subjects including mathematics subjects at university, especially applied mathematics, including the subject of statistical probability, must perform the purpose of supporting future careers for students This is not only an urgent and plausible requirement of the practice but also related to the theoretical issue of the process of teaching probability statistics to students and preparing for the career support process for them when still studying at school The practice of teaching probability statistics at Vietnam Maritime University is setting requirements for training students to support their careers There is already some experience with this process, but it is these experiences that need to be enlightened by scientific reasoning In order to serve the best practice, it is necessary to find specific solutions to help train students of the maritime industry oriented to support careers with high efficiency in the process of teaching probability statistics Looking back on the relationship between teaching probability statistics and career support, there has not been a systematic and comprehensive study of that issue in our country systematically For the aforementioned reasons that we have chosen the subject: “TEACHING PROBABILITY - MATHEMATICS STATISTICS TO SUPPORT CAREER FOR VIETNAM MARITIME UNIVERSITY'S ECONOMIC, TECHNICAL STUDENT” Overview of research issues 2.1 In the world In the process of teaching Mathematics in general and statistical probability in particular in the world today, there is a general trend: reducing academic nature, increasing practice and applying it to professional practice Because there are many works on the subject of statistical probability teaching, but within the limited scope of the topic and with the available resources, the topic only points through a number of authors and representative works such as Henry M (1994, Coutigno C (2001), Briad J (2005), Wozniak F (2005), Wilbert J McKeachie (England) et al, Susan Miles, Artaud M., … These studies show that many studies on the subject of statistical probability teaching emphasize the need to pay attention to practicality, raise learners' awareness of the application of statistical probability in life , establishing the relationship between teaching statistical probability and training in economics, engineering, medicine associated with the development of capacity used in teaching mathematics in general and corpus The statistical productivity in particular in the world today has a common trend: reducing the academic nature, enhancing practice and applying it to professional practice Because there are many works on the subject of statistical probability teaching, but within the limited scope of the topic and with the available resources, the topic only points through a number of authors and representative works such as Henry M (1994, Coutigno C (2001), Briad J (2005), Wozniak F (2005), Wilbert J McKeachie (England) and their partners, Susan Miles, Artaud M., These studies show that many studies on the subject of statistical probability teaching emphasize the need to pay attention to practicality, raise learners' awareness of the application of statistical probability in life , establishing the relationship between teaching statistical probability and training in economics, engineering, medicine associated with the development of students' ability to use statistical probability for the future careers 2.2 In Vietnam In recent years the study of issues related to vocational competencies, the relationship between university mathematics, especially statistical probability, with the process of formation and development of occupational competence has been very concerned There have been many educational scientists and basic scientists interested in researching on this issue as: Nguyen Chien Thang, Nguyen Anh Tuan, Le Ba Phuong, Đo Thi Trinh, Ngo Tat Hoat, Đang Van Uy, Ta Huu, Đao Hong Nam, Hoang Nam Hai, Pham Van Trao Research works mentioned above, can draw some comments as follows: -

Occupational competence meets work output standards and it is an important basis for the process of setting training standards - The content of occupational competence is realistic and can be assessed and measured - In addition to the knowledge, skills and attitudes of employees, occupational competence also contains the necessary principles to implement all or some of the specific occupational labor contents 1.1.3 Capacity of economic and technical maritime jobs 1.1.3.1 Maritime economic profession capacity Thai V.V and his colleagues reviewed nearly 20 important projects on occupational capacity that were scattered in nearly 40 years (1973 - 2009), a similar number of works in the field of public maritime economy published over 20 years (1990 - 2011) shows that maritime economic career competencies are related to all three areas of commerce, logistics - supply and management with 71 component capacities both general and specific (Appendix 7), in which competencies are compatible with the support of statistical probability include: - Regarding commercial activities: Competence in accounting and financial management; Ability to analyze statistical data; Risk management capacity; Competence in maritime law and insurance; Competence on tax sequence - Regarding the supply field: Capacity of supply chain management; Goods inventory capacity; Warehouse management capacity; Port traffic control capacity; Ability to plan and operate; Capability management and handling - shipping; Capacity of network design and optimization - Relating to the field of Management: Competence to think problem solving; Time management capacity; Planning and conditioning skills; Time management and performance 1.1.3.2 Competence in marine engineering By analyzing STCW's specific maritime technical labor requirements and competencies that need to be emphasized in ABET's technical training as well as output standards of Vietnam Maritime University, we think that basic capabilities that statistical probability is likely to affect such as: (1) Capacity to receive, transform and process information; (2) Capacity to apply mathematical knowledge in practice; (3) The ability to explore new knowledge, self-study, and self-research, the statistical probability is also capable of supporting a number of specialized capabilities of the maritime profession such as: (4) Positioning capacity ships at sea based on the theory of errors; (5) Capacity to respond and handle emergency situations at sea; (6) Competence in applying mathematics, namely statistical probability in the use and operation of maritime equipment; (7) Management capacity, organize a team on board to overcome troubleshooting; (8) Capacity to organize the mechanization of port loading and unloading, as well as to calculate and select beneficial options; planning loading and unloading work at the port; (9) Capability to organize operation management at ports; organization of warehouse management and exploitation; select the most effective exploitation plan; (10) The system's ability to use operational survey and evaluation devices to detect and promptly solve incidents; (11) Capability to use appropriate tools for common onboarding and repair activities, evaluation and quality control of equipment manufactured and manufactured in the workshop organization of warehouse management and exploitation; select the most effective exploitation plan; (10) The system's ability to use operational survey and evaluation devices to detect and promptly solve incidents; (11) Capability to use appropriate tools for common onboarding and repair activities, evaluation and quality control of equipment manufactured and manufactured in the workshop organization of warehouse management and exploitation; select the most effective exploitation plan; (10) The system's ability to use operational survey and evaluation devices to detect and promptly solve incidents; (11) Capability to use appropriate tools for common onboarding and repair activities, evaluation and quality control of equipment manufactured and manufactured in the workshop 1.2 Professional support for workers of maritime economic and technical fields 1.2.1 The concept of career support Career support in colleges and universities is understood to create career opportunities for students, that is, create opportunities and conditions for students to approach and implement (work) with careers related to the career their future through course knowledge, through forging activities, apprenticeship 1.2.2 The concept of career support for students in maritime economics and engineering Career support for students in maritime economics and technology is to assist them in the process of maritime vocational training, which can be interpreted as The school's teaching activities are all geared to helping students approach, get acquainted and even practice while studying at the school 1.2.3 The relationship between career support and career capacity development relationship between occupational capacity and career support At the same time, based on analysis, research on output standards, professional practice gives the statistical probability factors that can support career for students of maritime engineering and economics - Provide views on the process of teaching probabilistic career support statistics to students in maritime economics, purposes and requirements of this process - Organize surveys and analyze the status of teaching statistical probability for maritime students in the direction of career support at Vietnam Maritime University in order to assess the reality of teaching the subject of statistical probability, thereby orienting the teaching of statistical probability towards developing maritime professional capacity for students - Clarify the characteristics of physiology, learning activities of maritime students compared with other subjects at Vietnam Maritime University Therefore, we determine that teaching statistical probability at Vietnam Maritime University in the direction of supporting career for maritime students should meet the following requirements: Firstly, the content of teaching corpses Statistical capacity must be associated with practice and contribute to supporting the maritime career, especially the examples and exercises related to knowledge of statistical probability in order to maximize the role of statistical probability in occupation right in the learning process Second, students must be trained in the ability to use statistical probability as a tool to solve real-life maritime problems and problems Thirdly, prepare students to be interested in their careers, create learning motivation in general and study statistical probability in particular while still in school to help them gradually approach and practice the model occupations that use statistical probability The above results are the theoretical and practical basis for us to propose some methods of teaching statistical probability towards career support for maritime students at Vietnam Maritime University in Vietnam in chapter II CHAPTER II THE MAJOR MEASURES TO PROVIDE OCCUPATIONAL SUPPORT FOR STUDENTS OF THE MARINE ECONOMIC AND TECHNICAL THROUGH THE TEACHING OF THE STATISTIC CAPACITY AT VIETNAM MARITIME UNIVERSITY 2.1 Orientation to develop measures 2.1.1 Orientation Pedagogical measure is built on the basis of ensuring the content of the program, providing students with basic knowledge of the subject of statistical -

During the learning process, students have also actively thought, participated in building lessons, discovered and solved problems, actively contributed opinions to make The classes are more exciting 23 - Students gradually grasp the basic knowledge of the subject more firmly, and at the same time help students to form a number of vocational skills, meet the requirements of maritime professional practice - The effectiveness of empirical lectures in helping students gain knowledge about maritime careers is highly appreciated, teachers have used positive teaching methods that are highly practical for students to implement * From the students when participating in lectures We send votes for students to self-assess some of their occupational skills before and after the experiment We see that there has been a certain change, most students have confirmed the level of development of their occupational skills, namely: - Self-assessment results on the level of excitement, toxicity Establish, positive and creative students in the private lessons are at a high level, students are more active when participating in learning activities - The level of understanding of maritime professional practice knowledge after real hours of study also has a positive change, students self-assess their level of understanding of occupational practices with development - The majority of students in the class are conscious of actively participating in training sessions and self-training at home Many children feel more confident, more brave - Their ability to reason and solve problems is logical and coherent; the ability to speculate and reason when meeting situations related to marine professional practice is also improved 3.7.3 Assessing the development of maritime vocational skills of students In the evaluation, the thesis focuses on the role of statistical probability subject with the development of occupational skills by applying subject knowledge into practice Economics, marine engineering were presented in Chapter and Chapter Through observation, interviews, gathering opinions of teachers, students and maritime experts, the thesis assessed: - About ability to receive information from practical situations - About the ability to convert information from practical situations about mathematical models - About the ability to solve problems with knowledge of statistical probability subjects - About the ability moving from results of solving mathematical models to solutions of practical situations in maritime economics and engineering The experimental process shows that, by applying measures to use problems with practical situations in the economic industry, maritime technology has helped students see the content of statistical probability in different situations of industry practice Also through experiments shows that students are very active and interested in carrying out the activities and steps mentioned in the process of solving problems Through this, students determine the core of the statistical probability subject of the problem with practical situations in economics, maritime engineering, gain occupational skills to a 24 certain extent in turning the problem there are practical situations in economics, maritime engineering about the problem of "pure mathematics" and vice versa CONCLUSION OF CHAPTER III Through the process of experimental training round 1, round at Vietnam Maritime University, together with the obtained results and the data processed by statistical methods, observation methods, methods The survey has a basis to draw the following conclusions: - Students have shown their ability to confidently and understand their profession, they see the role of statistical probability in the maritime field - Measures and directions for implementing the proposed measures not only create conditions for students to acquire good subject knowledge, but also help them acquire practical knowledge, fostering their experience in the process life, career experience, ability to accept and cooperate with others, enabling students to assert themselves, students understand more clearly the role of this subject with specialized subjects in the training program and carry out maritime career This is very important for students, which is the initial foundation for their future economic activities -
