ORGANIZING THEME-BASED TEACHING IN PHYSICS IN HIGH SCHOOLS

Abstract. Theme-based teaching is considered as one of effective methods in which the teachers no longer play a simple role as communicators, they have become designers, organizers, instructors for each individual or small-group during learning activities. At the same time, the students are self-sufficient to dominate the learning content, can actively achieve the objectives of knowledge, and form significant skills as well as attitudes meeting the subject program. The students are attracted to learning activities to solve real situations, directly observing, discussing, making experiments, solving personal problems, and then grasping the useful suitable methods to acquire new knowledge as well as capacity development.

In theme-based teaching process, it is necessary to change from passive learning to active self-studying and develop self-studying inside schools and outside school. In each lesson, there is always the guidance of the teacher. Therefore, this article is concerned with the organization of self-studying activities for students during the process of organizing theme-based teaching in Physics to improve useful skills.

Keywords: Theme-based teaching, self-studying activities, competency, problem - solving.

1. Introduction: creative thinking, encouraging self-studying to cre-

Resolution No. 29-NQ / TW dated November ate a sound basis for learners to continue updating 4, 2013 of the 8th Central Conference - Term XI new knowledge, improving professional skills. To do on fundamental and comprehensive innovations of this, it is necessary to change from majorly studying education and training with many specific objectives form in class to organize various forms of learning, proposed the following contents: enhancing the stu- pay attention to do social activities, extracurricular dents' creative abilities and self-studying in order to activities, and scientific research. Besides that, proencourage them to pursue lifelong learning; focus- moting the application of Information Technology ing on teaching activities to develop the students' and communication in teaching and learning time

is extremely useful as well. The educators have long recognized the meaning of the self-studying method by the time. Teaching does not only transfer knowledge and ask students to try to memorize, but also importantly orient and enable the students to have golden opportunities to enrich new horizon of knowledge. Training self-studying skills is the best method to create strong motivation for students during the learning process. Self-studying helps the learners to be proactive in lifelong learning, have clear learning objectives to affirm their capacity and to contribute all their efforts on the society. Physics is one of natural science subjects, there are many contents associated with the daily life of students. Therefore, students will be less interested in the subject with traditional class teaching methods; moreover, they will have the lack of updates, they are easy to fall down illusion that knowledge which they have to learn inside the class is strongly different from real life. Furthermore, the presentation of knowledge with content-orienting textbooks makes the class stressful in reasoning, reasoning, and interpretation. It is obvious that this type of class is happing in little practice with less applying knowledge.This leads it not to be suitable for positive teaching methods as well as the orientation of developing useful competences for students. Therefore, teachers should pay attention to the following requirements in teaching time: designing the plans to give attractively subject knowledge for each student and help their students to do self-learning activities; inspiring the students to solve practical problems as well as have effective learning styles without breaking the currents education program rules. To be able to solve some of the above problems, when designing lessons according to the theme, teachers should design basing on learning activities, in which students' self-studying activities need to be focused.

2. Content

2.1. The concept of self-studying activities

The nature of self-studying which meaning students are always the perceived owners has a strong

effect on learning content in a positive creative way to gain learning achievement. To achieve this, self-studying is a process that the students are aware of the necessary contents inside the class and to own into your inside knowledge. Self-studying has two levels: complete self-studying and self-guided studying, in which self-guided learning is a form of self-studying to dominate knowledge and develop skills corresponding to the guidance of teachers. During learning process, students are considered as the subject of the whole teaching process to take over the knowledge as well as the truth by their own actions. Teachers act as the organizers, the instructors in students' self-studying process with helping instructional materials class rooms, facilities, self-studying can be in the following forms: Self-studying does not only take place inside the school learning but also this form is extremely popular outside social life such as: communication activities, working environment, etc... With self-studying forms, students can learn from their mistakes or their friends' mistakes in order to exploit new knowledge in learning time. In addition, self-studying at home plays an important role in the academic achievement of students. The process of self-studying enables students to self-learn each part of the lesson, study further [5].

Thus, self-studying is an indispensable factor in learning activities, in which students are encouraged to know how to mobilize their emotion and creative thinking to acquire knowledge and to improve their good personality under the guidance of teachers. The high or low result of self-studying depends on the self-studying skills of each individual and especially with the students in high school. This also bases greatly on the guidance of teachers or instructional materials, facilities...

2.2. Self-studying activities in theme-based teaching Physics in high school

2.2.1. Design theme-based teaching process

Designing the theme-based teaching process is the final step in the process of building thematic lessons and designing teaching activities. In particular,

specific learning organizing activities for students can be done in class and at home. A series of learning activities showing pedagogical process has the five following learning activities:

Experiential learning activities

In career-oriented education stage in high schools, the creative experiential learning activities programs continue developing the capabilities and qualities after the basic education stage (in secondary school). This enables students to develop career-orienting skills as well as selective and adaptive competencies. At this stage, the programs are highly differentiated and elective. Students are not only assessed for their abilities, strengths, and career-related interests but also are consulted to train the basic qualities and competencies for future career.

In the teaching method before each new lesson on the class, the teacher organizes his students to study according to the materials in advance, do some experiential learning activities in practice with a system of exercises with adding new knowledge in the classroom. After the students have completed their learning, the teacher has them report in group or individual in front of the class.

2) Identifying and addressing problems

This is the fundamental stage in which students must mobilize their knowledge, skills, and experience to identify many sides of the problem. With the ability in identifying students' problems, students will express their own perspectives through the result report of the first stage. This is a basic stage to help teacher to identify students' understanding of potential problems in real life as well as enable teacher to give the tasks in accordance with the capacities of students. Students can work in group or individual. In these activities, teacher must have specific teaching methods, basic techniques, real situations and other facilities to call the first interest and to stimulate his students.

3) Forming and standardizing knowledge

Students begin studying the subject matters of

knowledge under the guidance of their teachers. This

activity needs to organize a variety of different learning forms. Throughout this, the students need to be inspired to collect and to process useful information from different information channels (books, newspapers, internet, real life etc...). Teacher demands their students to come up with many effective solutions, implementing measures to gain knowledge. This stage helps students to form new knowledge as well as has the students solve the problems raised initially that students themselves cannot solve. In the activities of students, teacher needs to have teaching methods and active teaching techniques with adding new knowledge. In teaching Physics, teacher needs to guide his students to do experiential learning activities. Because the students will test the correctness of the theory to remove the anti-scientific experience through these activities and they will standardize the content of the topic in their right target.

4) Applying knowledge

This is the stage to help students to practice and systematize their knowledge; moreover, they can apply their acquired knowledge to explain phenomena, to give solutions, to propose ideas to solve problems. Throughout this stage, students can enrich the knowledge; they can also make learning process meaningful to develop the significant abilities to solve potential problems and other competencies. Teachers can instruct students to do individual activities, group activities through the exercises by designing many interesting questions. 5) Enlarging knowledge into practice

This stage helps students to develop their abilities to solve problems and create creativity thinking. Teachers should decide the available resources such as reference books, journals, information from the internet ... so as to encourage students to continue enlarging the knowledge that they have learned from real-life activities. In these activities, teachers should use the essential questions, the system of exercises after studying the subject to enrich knowledge.

From the five activities in the above-mentioned teaching process, any activity with self-study and

self-learning activities of students may be present or not present by teacher. Because the teacher has the key in orienting knowledge, providing materials and facilities ... Students will complete the assigned tasks in the form of self-studying activities in individual or in group. The self-studying process is often followed by the steps below:

+ Step 1: Identifying objectives, making plan and solving assigned tasks

- Identifying characteristics of content, knowledge and skills. From to this, self-studying plan is developed. Knowledge is systematized. Students can determine the relationship between acquired knowledge and new knowledge. Therefore, when acquiring new knowledge and skills in the process of learning, students have to find obvious relationship between newly acquired knowledge and existing knowledge. The acquired knowledge and existing knowledge are combined into an unified system turning into the subject's own capital facilitates mobilizatedly when in needed.

+ Step 2: Make a report and discussion Through self-studying activities in the step 1, knowledge is presented systematically, but it is subjective, has lots of mistakes and shortcomings. Therefore, we need to socialize learning products. That means students have to report by their self-expression or evaluation for the individual products according to the mastery level of the products. The group having creative ideas is expressed in a specific form so that each student and teacher can observe and analyze to evaluate the accuracy of the products. The particular study that students can express in many different ways such as: summarizing, making outline, learning cards, setting up system diagrams, making reports, doing talk activities and making projects, ... Finally, discussing and debating activities about newly learned things of students is carried out by the students' explanation and protection to their products. The other team members and teacher listen, analyze, give ideas to make a producing progress.

Step 3: Evaluating and adjusting Teacher instructs students to self-assess, or evaluate each other (among group members). Just like that, through practice gradually, students know how to self-assess after learning each content or each part in the program. After the assessment, the learners can compare themselves; identify the mistakes, the cause in order to correct the knowledge content and to meet demanding skills. From to this, the students can adjust the way of learning so that it is more and more suitable.

Step 4: Applying knowledge In order to answer the question: "What is the purpose of learning to do?", it is necessary to observe in learning situations and real life. Applying knowledge and useful skills is the last step of the learning or self-studying process.

Thus, in organizing learning activities, theme-based teaching process is considered as a series of learning activities with a combination of active teaching methods and techniques in which self-studying method plays an important role. If teachers create conditions for students to have golden opportunities to enlarge new horizon according to teacher's plans, the building of theme-based teaching and designing teaching process will be very convenient for the program with the currents educational task is: "Renovating teaching content in the direction of streamlining; modernizing, being practical suitable for ages, qualifications and professions; strengthening practice, applying to practice ... [3].

2.2.2. Characteristics and objectives when teaching Physics in high school

Physics in the field of natural science is said to describe as natural phenomena and properties of matter. Besides that, the contents of Physics also includes from basic particle structure to cosmic structure, which is the basis of many important engineering and technology branches. The knowledge selected in the teaching program is considered as the classical physics knowledge. This needs for the proper understanding of natural phenomena, for daily life, even for many

jobs in technical industry. Therefore, many tools and technical equipment are electric currents being used in common life and production nowadays.

In addition to know about the importance of specific cognitive methods of Physics such as experimental methods, model methods, similar methods etc., it is necessary to train and improve capacity development for students in order to contribute on the development of all potential competencies regarding physical fields. Therefore, the following objectives need to be achieved:

- The content of knowledge must be presented reasonably with the amount of suitable time. Teaching must be consistent with the ability of students to absorb. The amount ofknowledge and skills required in each topic should be balanced with the implementation of the tasks during teaching process in physics, especially with the organization of active learning activities.

- Objectives to be given in the system such as: concepts of things, phenomena and physical processes commonly encountered in real producing activity; quantities, laws and basic physics principles; the main contents of some of the most important physics theory; common applications of physics in real producing activity and contribution to deepening the principles of natural science. Topics should be practical, highly career-oriented.

- During the teaching process in physics, through the implementation of learning tasks, students can develop the elemental capabilities of common competencies such as self-learning ability, problem-solving ability, aesthetic capacity, physical fitness, spirit, communication competence, work in group skills, and communication technology ability.

3. Conclusion

The organization of self-learning activities for students in the process of theme-based teaching in the orientation of developing capacity focuses on self-studying and self-controlling when studying general physics. The organization of these activities requires teacher to invest all efforts to design learning activities with the goal of helping students to gradually dominate scientific knowledge, the

students have golden opportunities to use potential knowledge to solve practical problems in real life. To do this, teacher needs to foster and master knowledge in many different fields with applying flexible teaching methods and techniques actively. Since then, building good topics and practical situations in teaching Physics to develop students' essential competencies, self-learning ability and ability to solve practical problems.
