Keyword : Development of Card Media, Scientific Approach, The Practical and Effectivity INTRODUCTION Student's achievement to understand of problem is definited by student's interest to teacher. The one of student’s interest by media using in teaching learning (Muchith, 2008: 37). The observation's result of mathematics learning's activity in junior high school show that, the card media is less to use in teaching learning. Beside that, learning's process is still using books and directive's book. Student learned to think concrete, so that student have motivation to study. It means that, learning media is important to use in mathematics learning. Hamalik (on Arsyat, 2011: 15) explain that learning media on the teaching learning process can make student's motivation be increasing. Mathematics learning's process can make student more active on their mental or physical with scientific approach. On education's rule Number 68 Year 2013 about standart of education's process which education rule with scientific approach. So that, mathematics learning need scientific approach on learning process. Scientific approach can increase student's attitude, knowledge and skill, including observation, thinking process and trying to mailto:forerik99@gmail.com 34 Mathematics Education Journals Vol. 1 No. 2 August 2017 P-ISSN : 2579-5724 E-ISSN : 2579-5260 http://ejournal.umm.ac.id/index.php/MEJ solve a problem (Komara, 2014: 88). Scientific approach can make by card media. Card media is visual media which has information to give a student. The form of nformation are picture and text (Arsyat, 2011: 119). The research which do Nur faizah (2013: 64) about card media on mathematics learning process explain that card media can increase student's motivation and make student more active. Rahayu (2013: 5) found that card media on mathematics learning can help student to understand a problem. THE METHOD OF THE RESEARCH The developing of card media with scientific approach use Borg and Gall model. The reasearch to produce a product and make test about product's effectivity. The research and the develop has a steps : (1) analyze of problem; (2) collect a data; (3) product design; (4) validate of problem; (5) revise of design; (6) test a product; (7) revise a product (Sugiono, 2015: 409). The instrument's research use sheet of validation's media, and sheet of observation's test. Sheet of validation's media used to know the valid of card media. Questionnaire and sheet of observation's test used to measure of cars media's practical. The level of card media effectivity can be seen by student's clasical achieve after follow the learning process with card media. The card media test was conduct ed of twentythree student class VII of junior high school of Muhammadiyah Malang. THE RESULT AND THE DISCUSSION The result of analysis a problem that is card media is not focused on student. It means that, need a card media which can make student's motivation on learning. The card media is scientific approach. On the collecting of data step get a matter of social arithmatic with content of competence, base of competence, and learning indicators. The data is for design of media. The content of competence and base of competence on the matter social arithmatic can be seen by table 1. 35 Mathematics Education Journals Vol. 1 No. 2 August 2017 P-ISSN : 2579-5724 E-ISSN : 2579-5260 http://ejournal.umm.ac.id/index.php/MEJ Table 1 The content of competence and base of competence on the matter social arithmatc The content of competence The base of competence 4. trying on the concrete aspect (using, making, modificating) and the abstract aspect (writting, reading, counting, drawing and arranging) which similarity with theory of the study 4.11. Solve a problem which have relation with social arithmatic (selling, buying, discount, percentage, etc). Table 2 The indicator of social arithmetic Learning indicators 4.11.1. Student can decide a selling price, buying price, profit, loss, profit percentage, and loss persentase 4.11.2. student can decide a singular price, tax and discount 4.11.3. Student can decide a gross, tare and net Design process do three steps : (1) make a format; (2) make a design; (3) make a media. Design process do by make a design with coreldraw. The design's result of card media contain of three type and different matter. The first type of card contain about gross, tara, gross percentage, tara percentage, selling price and buying price. The second type of card contain about discount and tax. The third type contain about gross, tare and net. On every card contain five characteristic of scientific approach with instruction. The first card with observation characteristic, can be seen on picture 1. Picture 1 : The result of card media design 36 Mathematics Education Journals Vol. 1 No. 2 August 2017 P-ISSN : 2579-5724 E-ISSN : 2579-5260 http://ejournal.umm.ac.id/index.php/MEJ The second card with observation characteristic, can be seen on picture 2 Picture 2 : The result of card media design The third card with observation characteristic, can be seen on picture 3.
