Professional groups still do not have official documents specifying the organization, operation, and tasks of professional groups. The organization and operation of professional groups are often organized by schools themselves on the basis of professional groups to effectively implement the educational goals of the school as well as improve the quality of teaching of teachers, the learning of students; help school managers easily manage human resources and the quality of educational activities in the school. Therefore, the organization and operation of professional groups are often stipulated in the working regulations of the school. If the school's regulations create favorable conditions for professional groups to operate, it will help the professional groups operate effectively and vice versa, if the school's regulations are unclear, or do not mention the activities, functions, and tasks of professional groups, the activities of professional groups seem to be ineffective, or even non-operational.
- The structure of the school's teaching staff.
The structure of the school's teaching staff has a direct impact on the quality of professional group activities. In fact, for secondary schools with a full staff of teachers according to position, it will be very convenient to organize professional groups. In the activities of professional groups, the teaching staff will have good spirit and responsibility in performing tasks as well as regulations of the school, team, and professional group. For secondary schools with a small staff of teachers, lacking in comparison to the prescribed positions, it will lead to a large number of contract teachers. Therefore, when organizing professional groups, contract teachers are often not enthusiastic and have low responsibility in the activities as well as all other activities of the professional group.
- The conditions of facilities, equipment, and financial resources meet the operational requirements of the school's professional groups. This is a necessary condition in improving the teaching quality of the teaching staff, thereby improving the operational quality of the professional group in implementing the teaching goals as well as the general educational goals of the school.
1.5.2. Subjective factors
- Capacity of school management staff.
The management of professional group activities is the job of school managers. If school managers have good management capacity, enthusiasm, responsibility in their work, and dedication to the activities of professional groups, the management and maintenance of professional group activities will have high performance results, and the teaching staff in the professional groups will perform their professional tasks seriously and with quality. If the management staff's capacity is weak and they lack close attention to their work, the quality of management of professional group activities will not be high, the teaching staff will lack self-awareness in their work, and the activities and implementation of professional group tasks will be more formalistic.
- Management capacity of team leader, professional group leader.
The professional group is under the direct management of the professional group leader and the maintenance responsibility of the professional group leader. Therefore, the management capacity of the group leader and professional group leader has a direct impact on the maintenance of the activities as well as the quality of the professional group's activities. A group leader and professional group leader with good capacity and ethics will contribute to gathering the strength of solidarity in performing the tasks of the teaching staff, thereby improving the quality of professional activities according to the educational goals and tasks assigned by the school.
- Capacity of teaching staff.
The teaching staff are individuals who directly participate in the professional group, performing professional tasks according to the plan of the group and the professional team. Therefore, the capacity of the teaching staff will have a direct impact on the results of the group's professional tasks. A good team of teachers with high professional capacity and expertise will make the overall quality of the professional group's activities high, meeting the educational goals of the school.
Chapter 1 Conclusion
The professional group is an important component in the organization and management of secondary schools. The professional group plays an important role in the process of implementing the innovation of the education and training program, and is the "center" for teacher training to help teachers improve their professional capacity. At the same time, the professional group is the place to directly manage and train teachers in terms of awareness and professional expertise; discover the strengths, weaknesses, advantages and difficulties of each teacher in the teaching and education process. Therefore, the management of professional group activities plays an important role and significance in helping managers grasp the quality of the teaching staff and the quality of teaching and education of the school.

CURRENT STATUS OF MANAGEMENT OF PROFESSIONAL GROUP ACTIVITIES AT SECONDARY SCHOOL IN HONG BANG DISTRICT, HAI PHONG
2.1. Overview of the current situation survey
2.1.1. Survey objectives
Collect information as a basis for assessing the current status of professional group activity management in secondary schools in Hong Bang district, Hai Phong as a basis for proposing management measures to improve the quality of professional group activity management.
2.1.2. Survey content
- Current status of professional activities at secondary schools in Hong Bang district.
- Current status of management of professional group activities of secondary schools in Hong Bang district.
2.1.3. Survey subjects
120 people are managers and teachers of 8 secondary schools in Hong Bang district, specifically: Secondary school managers: 16; Secondary school teachers: 104.
Secondary schools include: Bach Dang Secondary School, Hong Bang Secondary School, Hung Vuong Secondary School, Ngo Gia Tu Secondary School, Nguyen Trai Secondary School, Phan Boi Chau Secondary School, Quan Toan Secondary School, Tran Van On Secondary School.
2.1.4. Survey method
- Questionnaire survey.
- Interviewing a number of school administrators and teachers about the advantages and difficulties in professional group activities and managing professional group activities at secondary schools.
2.1.5. How to process survey results and score evaluation
Use statistical software to calculate and check data when collecting information from managers and teachers.
Includes assessment levels:
* For implementation level: Evaluated according to 3 levels: often (3 points), sometimes (2 points), never (1 point).
For response level: Evaluated according to 3 levels: good response (3 points), partial response (2 points), no response (1 point).
To determine the scale, we calculate the scale score using the formula:
(Maximum score - Minimum score): Number of levels
The distance between the levels of the scale is: (3 - 1): 3 = 0.67 points. The minimum score of level 1 is 1 point.
The minimum score for level 2 is: 1 + 0.67 = 1.67 points. The minimum score for level 3 is: 1.67 + 0.67 = 2.34 points. So the 3 levels of the scale are as follows:
Low level: 1 to below 1.67. Medium level: 1.67 to 2.34. High level: 2.34 to 3.
* For performance results: evaluated according to 4 levels: good (4 points), Fair (3 points), Average (2 points), Poor (1 point).
For the level of influence: assessed according to 4 levels: very influential (4 points), influential (3 points), little influential (2 points), no influential (1 point).
To determine the scale, we calculate the scale score as follows:
(Maximum score - Minimum score): Number of levels
The interval between the levels of the scale is: (4 - 1 ): 4 = 0.75 points. The minimum score of level 1 is 1 point.
The minimum score for level 2 is: 1 + 0.75 = 1.75 points The minimum score for level 3 is: 1.75 + 0.75 = 2.5 points The minimum score for level 4 is: 2.5 + 0.75 = 3.25 points So the 4 levels of the scale are as follows:
- Low level: From 1 to below 1.75.
- Average level: From 1.75 to below 2.5.
- Good level: From 2.5 to below 3.25
- High level: From 3.25 to 4.
2.2. Current status of organization and operation of professional groups at Hong Bang district secondary school
2.2.1. Organizational structure of professional groups
The professional groups in Hong Bang district secondary schools are specifically structured as follows:
- Professional groups by school unit are professional groups with a large number of teachers: Math group 6,7,8,9; Literature group 6,7,8,9; Physics, Chemistry, Biology, Technology, Foreign Language, Physical Education, elective groups.
- Professional groups by district unit because there are few teachers: Music and Art groups.
On average, each school has about 17 professional groups and the number of group members is based on the structure of teachers directly teaching.
The professional group leader is proposed by the professional group and assigned by the principal at the beginning of the school year.
Within the scope of the topic, we delve into the following subject groups: Math, Physics, Chemistry, Literature, History, Geography, English. The structure and number of subject groups at 8 secondary schools are listed as follows:

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

Through statistics, it can be seen that the Math and Literature subject groups have a large number of subject groups. Each school (except Quan Toan Secondary School) consists of 4 groups divided equally among grades 6, 7, 8, and 9. These are the 2 subjects with the most content and number of lessons per week and year. For the remaining subjects, each school has an average of 1 subject group. Hong Bang Secondary School is the school with the largest number of subject groups (21 subject groups). The difference is that according to the characteristics of each school, according to the direction of the Principal, Hong Bang Secondary School is a school with a large number of teachers, so to ensure that the subject group activities are smooth, the school is divided into many groups.
2.2.2. Current status of professional group activities in secondary schools
To study the current situation of professional groups in secondary schools in Hong Bang district, we used the question: What is the teacher's assessment of the current situation of professional group activities in the secondary school where he/she is working? (Question 2, Appendix 1), and processed the survey, we obtained the results as shown in Table 2.2 below:

Professional group activities in secondary schools are not carried out regularly, with an average value of 2.24. In which, the level of implementation of each content is different. Specifically as follows:
* Current status of professional activities and topics of professional groups at secondary schools in Hong Bang district
Professional group activities and professional topics are carried out quite regularly. These are two contents included in the regulations of the General School Charter and specific regulations of the Department of Education and the school, with average values of 2.40 and 2.34 respectively, ranking 1/5 and 2/5.
The professional groups strictly implemented the distribution of the 37-week professional program according to the general school program that had been developed and approved by the District Professional Assessment Council. The professional groups actively developed teaching topics by subject, interdisciplinary, and integrated to ensure flexibility and effectiveness. Specifically, in the 2015-2016 school year, 210 topics were developed, and in the 2016-2017 school year, 185 topics were developed. The professional groups implemented the topics in district-level professional activities and in class periods at school.
The Department of Education and Training issued Plan No. 33/KH-PGD&DT for the 2015-2016 school year on directing the implementation of "Innovation in teaching methods and innovation in testing and assessment towards developing the capacity of secondary school students", secondary schools have developed professional activity plans (schools, groups, teams), in which the orientation is to innovate the form and content of professional group and team activities based on research on students' learning activities; towards developing students' capacity. At the same time, organize professional activities according to practical and effective topics; develop quality teaching topics, stipulate the number of professional activities per week, month, and professional activities of professional groups and teams. In the 2015-2016 school year, the Department of Education organized professional activities at the district level and carried out 46 meetings.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
