Generally people in Indonesia have less English ability than other people in the world. It shows from limited ability in communication by English. However we know that English is needed to optimize science in Indonesia, especially mathematics. We can see that Mathematics is wrote and published by English. To get science easily and fast, we need expertness in English. With this expertness the new science especially mathematics from others developed countries is followed easily. So to develop mathematics notably in teaching learning we must communicate mathematics through English.
The meaning of math learning through English is learning process that every material, teaching process, and assessment are given in English. This learning mathematics through English still use national curriculum applied. It is include contextual teaching and learning. So, syllabus and assessment system are developed to one’s curriculum. Nevertheless, school can add, extend, and deepen curriculum agree with mathematics international development with pay attention values and Indonesian culture.
Project aim of teaching learning math through English are:
1.Producing alumnus who have high competence in mathematics;
2.Producing alumnus who have expertness in English;
3.Developing mathematics through English appropriate with international development;
4.Developing competitiveness in international about mathematics science;
5.Developing student communication ability in English, it is mean student have good expertness in English;
6.Connecting Indonesia in international mathematics development.
Stages of teaching learning mathematics development
Teaching learning mathematics through English starts in some school in Indonesia with mark national standard school. Then the schools to be international rate school must pass many stages. Some school practice teaching math with English in some class then all class step by step. Just some schools have potentials modal in input, process, education output that brave to try this project. From this case means with teacher ability in English, support facilities in teaching learning process, high readiness of student and parents, high budget, and supporting school committee.
The schools that try to practice it have effective and efficient in teaching learning process. In the output, these schools have exceeded on average of academic performance and nonacademic performance. Beside that, the schools show high commitment to go forward. They are indicated by enthusiasm, spirit, obligation, dedication, moral baking and intellectual which had been shown by headmaster, teacher, and school officer.
Implementation mathematics learning through English
In the implementation, intensity of using English to communicate from one school with other depends on the readiness of students and teachers. In first semester, usually language to communicate math is dominated by Indonesian language. Because the student still confuse with material that is given by English. But in second semester, the frequency to use Indonesian language is less. In addition, English to be language to communicate mathematics in class.
From research, the class with English as language to communicate mathematics has more ultimate than regular class, with Indonesian language as communication language. The students can understand the material with English and they also understand the concept of material. The students also have expertness in English than regular student. However to create teaching learning mathematics through English is not easy. There are many problems to create it. One of all is there are many teachers have troubles to do their assignment. The troubles are caused their limited English capability. The other troubles are limited to develop learning plan, limited to develop and utilize multi media, and limited of sources.
To solve these problems, we must prepare the teacher to hold English. Basically to the next teachers, they must readiness to teach mathematics with English. So we need their ability in English, they must held on English more than others. But to teachers that have teach in school, they must learn how to teach mathematics in English and develop mathematics subject through English. Although to develop math through English for old teachers is not easy, but they must effort it. It is caused from demand of school in this period.
Basic components to develop teaching learning math through English
Basically, teaching learning mathematics through English uses approach-system, so school as system. School as system consists of basic components which fitted together to get aim. They are contexts, input, process, output, and outcome.
1.Context
Context is all things that are beyond of school, but they have influence on teaching learning math. Cause it; context must be connected with school. Context consists of technology and science development, values and society expectations, government backing, claim of globalization and autonomy, and demand of self development.
2.Input
Input is all things that are needed to process. Input consists of school expectations (vision, mission, and purpose), curriculum, teachers, students, media and infrastructure, budget, and rule.
3.Process
Process is changing something to be something other. In education, process consists of teaching learning, school management, and school leadership.
4.Output
Output is work activity of school. It is school achievement that is resulted from education process in school. It can be measured from quality, affective, productivity, efficiency, and innovation. Especially to quality, school output is said high quality if school achievement, notably learning achievement of student is shown from high score in academic notably mathematics and good performance non academic.
5.Outcome
Outcome is effect from alumni in long period. Education outcome comprises continuing grade opportunity, job occasion, self development, and social and economy development
Development focus for school that use English in mathematics learning.
1.Development mathematics material through English.
Mathematics material in English is needed to develop appropriate with international development. Thus, schools that perform this program must build national and international web to get newest material.
2.Learning media development
We know that mathematics learning through English is new matter and it has high complicated than regular learning using Indonesian language. So, it need learning media to make students understand easily. Education media in this case has meaning more general which teaching tools has characteristics; actual and concrete. The media as electronic multimedia with animation also can be used.
3.Rising mathematics teacher competence in English
Mathematics teachers must increase their English ability continuously if they want to teach math through English. Courses for teachers from school or from other education institute, using English for habit in school, and using mathematics book in English are manner to increase English ability.
4.Communicate in English to be habit in school
Students and mathematics teachers always use English to communicate in class, so it will create good result from learning mathematics through English.
5.Consistency of leader in school
Mathematics learning through English will run well if it is support by management and leader in school.
Process learn mathematics through English
In the class, teacher must communicate math slow but sure, because mathematics is complicated subject. There are many chapters in mathematics that is beyond mind of people. That is like geometry. Student will confuse if they learn math faster, moreover with English to communicate. There are many new vocabularies that will be learned by students. Suppose in basic math, we know addition, subtraction, multiplication, and division. But it will be the new vocabulary for student.
More complex, math talk about set, empty set, variable, and equation. That will be given in junior high school. Teacher must be teach patiently and give some problems to solve by students. So, student can understand about it. Greater level is geometry. Because geometry is beyond mind of people we need to consider psychology of teaching. To explain geometry, teacher must explain the general characteristic of 3D object. After it, students will understand details characteristic of 3D object.
Conclusion
Mathematics is science that is important to learn and English can support math to develop it. But learning mathematics through English is not simply, there are many things that must be paid attention. Teaching student use English to communicate also need patience. Students must learn not only mathematics as subject but also vocabularies in English.
