Introduction
Royal language is the official terminology used to communicate between people in different levels in Thai society.Royal language learning in secondary schools have yet succeeded as many educators would have wanted because students do not use it correctly.Also the achievement in using of the royal language has been relatively low or does not meet the criteria.It is due to the fact that they are lack of proper techniques.Teachers should adopt different techniques to enable students to improve their learning potentials.In order to manage the learning process to be effective, management should focus on the learning experience especially practical work to allow students to feel the real work.In addition, learning experience provides students with hands-on lessons, to learn how to solve problems, to plan and to be able to do analytical thinking to learn and build their knowledge.
The project-based learning is one of the learning process where learners are emphasized and encouraged to take part in learning systematically, which aims to promote critical thinking.Helping each other build knowledge base or problems solving by studying and doing research.When the project is completed, new knowledge must be obtained and can put that knowledge to good use.The principle of learning is that students can choose issues or problems on their own.Students will learn to share their learning with others and bring the knowledge to use in everyday life.The learning of Thai royal language by Mattayomsuksa 2 students (8 Grade) using the project, therefore, promote the process of learning, critical thinking and self-knowledge building.

Lesson plan on a royal language using the project-based learning has an effectiveness index of 0.6196, or 61.96 percent 3. The achievement of 8 graders who studied royal language using the project-based learning is higher prior learning.The level of statistical significance is 0.05 4. The two students were satisfied with the royal language learning using project-based learning with an average of 4.62.Overall, student's satisfaction is in the highest level

Discussion
1. Lesson plans on Thai royal language by using project-based language learning gave efficiency of 87.35 / 83.64 which means that the evaluation and testing of students in each plan.It yielded a score of 87.35 and an evaluation after learning achieved 83.64 percent of that Plan.This means that lesson plan which has been developed is more efficient than 80/80 set criteria.This is to say that the lesson plan on royal language has been developed systematically by studying concepts, theories, principle, related researches, learning activities, appropriate measurement and evaluation.Also Lesson plan has been assessed by experts.It can be used to manage learning effectively and consistently.The research done by Rawiwan Puangsombut (2010) who studied the development of lesson plan on the ability to compose Gap Yani 11 (Thai traditional poem) in Grade 7 students.By using an activity project, it is found that lesson plan has effectiveness of 81.30 / 81.61, and it is consistent with Boonrom (2012) who studied the development of event-based learning project on Thai royal language of 6 graders.The result of the activities of learning projects in Thai royal language has an effectiveness of 83.24 / 82.46.It met the expectation of 80/80 that we set.
2. Thai language learning on royal language has an effectiveness index of 0.6196, meaning that students who are learning made a progress of 61.96 percent of the curriculum.Therefore, it is consistent with the purpose of learning.It has content and learning activities that focus on practical problems and solutions in a real situation.As a result, learners can develop their potentials at all times.This consists with the research by Boonrom (2012) who studied the development of project-based learning on Thai royal language by grade 6 students.The result shows that students have made learning progress and the effectiveness index is 0.7015 which is 70.15 per cent.This is in line with the research by Somsai (2012) who developed activity learning projects in Thailand proverbs teaching women for 6 Graders.Students showed learning progress with effectiveness Index of 73.83 0.7383 percent.
3. The achievement of students using the royal language using project-based learning is higher after learning.The level of statistical significance is 0.05, which matched the hypothesis.This is because the project-based learning has lesson plans that meet individual differences.By allowing students to learn together, share ideas, find answers and solutions.This also consists with the research by Nak-klieng (2010) who studied the effect of learning a language, "Piece of cake" project by 6 graders.We found that an achievement and the ability to think critically higher than prior study.Boonrom (2012) who studied the development of event-based Learning Projects in Thai royal language by Grade 6 students found that student achievement is higher than prior study with level of statistical significance of 0.05 and it corresponds to Somsai (2512) who studied the development of learning project "Thai proverbs in teaching women" of Grade 6 students.She found students have made learning progress.The level of statistical significance is 0.05.
4. The 8 grade students were satisfied with the lesson plan on royal language subject using projectbased learning with an average of 4.62.Overall student satisfaction is in the highest level.Perhaps the management of learning projects heavily focused on students and the training focuses on practical experience.They learn how to obtain knowledge and learn of a variety of learning resources as well as bringing learning to use in everyday life with teacher only act as a mentor and an adviser.This gives opportunities to students to showcase their talents to the fullest, it also shows integration of knowledge and application to combine knowledge into practice.This is consistent with research by Sirakarn Suriyasakoolwong (2510: 76-86) who did the research on the effects of activity learning projects on subject "Making Klon Su Phap" (Thai traditional poem) by grade 12 students.They are very satisfied with the learning of Thai royal language.Moreover, Boonrom (2010) who studied the development of event-based Learning Project on royal language found that grade 12 students were highly satisfied with the learning.
The results show that lesson plans on royal language for Grade 8 students which were developed by the author are effective.It allows students to have systematically learning and achieved the set target.Therefore, it is suitable to be used in learning management and learning content development on others or to other subjects.


Teachers should allow students to study, research outside study hours.Teacher should also simulate and check the progress and provide ongoing support.


Indiscriminate student Grouping, they should mix students with different abilities e.g..good, moderate and weak students.


The teachers should focus on activities that students understand their roles and responsibilities as much as possible.


They should learn more about other projects or appropriate classes and should study in conjunction with other variables, such as the ability to think critically, persistence in learning attitudes toward the project, and so on.


They should study the learning, projects that can integrated with other subjects.Since learning project enable us to assess various abilities of the students.
