Keywords: module, word problem, quadratic equation

Most of teachers often use an explanation method in mathematics teaching and learning activities recently. This kind of teacher centered teaching and learning causes the students’ creativities obstructed. The students will lost their motivation in learning. Besides that, the role of the text book used by the teacher and the students cannot power them to reach the learning objective. One way that we can use to solve this problem is using a module in teaching and learning activities. Module can improve the students’ creativity and motivation since the students have a chance to do independent study. One of mathematics material that has many formulas judged by the students is quadratic equation. This material has not taught maximally especially the concept of quadratic equation in daily life. Therefore, the problem that is written in the module consists of contextual mathematics word problem.

This study is conducted to develop an English contextual mathematics word problem. This module is expected to be able to help the students learn actively and independently. This module is expected also to help the students learn about word problems in their daily life. Besides that, the students can learn about mathematics in English by using this module.

This module is developed by using ADDIE model that consists of five steps. The five steps are analyze, design, develop, implement, and evaluate. The analysis of quadratic equation teaching and learning is done in analyze step. The layout of the module is designed in the design step. The layout of the module is developed as word problem module in the develop step. The developed module is tried out to the lecturer, the teacher, and the students in implement step. In the evaluate step, the result of the try out is evaluated and there is a revision of some parts of the module that need to be revised. There are some steps in the tryout of this module, they are: (1) validity test of the module by the mathematics lecturer and mathematics teacher, (2) validity test of the English used in the module by the English teacher, and (3) readability test of the module by eight bilingual students of tenth grade. The qualitative or quantitative data are collected by using a questionnaire.

The percentage of validity test of the module is 91 %. It means that the contextual mathematics word problem module is very valid. The percentage of the validity test of the English that is used in the module is 75 %. It means that the English that is used in the module is valid. The result of readability test shows that the module can motivate the students to study. It is caused the module involves the challenging word problem and mathematical terms that needs deeper understanding. This module is revised by writing check your readiness, mini dictionary, and revised the passive into active sentences based on the tryout subjects’ suggestion or comment.

Based on the result of the tryout, the module consists of introduction, main activity, and closing. This module gives a new challenge to the students in learning. It is caused by the nonverbal quadratic equation word problems are written in English and they are related to contextual problems that they have not read before. This module also motivates the students to learn about mathematics in English. Besides that, the students can learn independently by using this module. It is caused by the module has systematical steps that can guide the students. The suggestion of this study is the next researcher shall do the tryout to check the effectiveness of the module in teaching and learning activities. Besides that, it needs to develop a communicative interested economical English word problem module with the other material.
