PENERAPAN PENDEKATAN PEMECAHAN MASALAH MENURUT POLYA MATERI PERSEGI DAN PERSEGI PANJANG UNTUK MENINGKATKAN HASIL BELAJAR SISWAKELAS VII B SMP NEGERI 10 JEMBER TAHUN AJARAN 2012/2013
Get PDFAbstract.In general, mathematics learning at schools is still a teacher centered, so the students become less active in teaching-learning process. Beside that, the students are also never given a problem-solving work done in groups. It causes the students become passive and just listen to the teacher’s explanation. It makes the students bored and invites difficulties in learning mathematics. It also causes the low score of the student learningachievement. Therefore, it needs a development of learning by applying a problem-solving approach as Polya says about square and rectangular objects to improve the student learning achievement of class VII B in SMP Negeri 10 Jember 2012/2013 academic year. Polya says, in a problem-solving approach, there are four steps, include: understanding the problem, devising a plan, carring out the plan, and looking back. Based on the research, the application of problem-solving approach, as Polya underlines, is effective to improve the student learning achievement in square and rectangularobjects. It is proved by the result of student learning achievement, which is from 58,33% to 88,89%.
Key Words:Polya’s problem solving approach, square and rectangular, student learning achievement

UPAYA MENINGKATKAN KETERAMPILAN DALAM MENYELESAIKAN SOAL CERITA MELALUI METODE PEMODELAN PADA KOMPETENSI DASAR MENGGUNAKAN BENTUK ALJABAR UNTUK MEMECAHKAN MASALAH, TERMASUK MASALAH ARITMATIKA KELAS VII SEMESTER I SMP NEGERI 1 MUMBULSARI
Get PDFAbstrak. Sebagai guru kita menyadari bahwa Matematika cenderung dipandang sebagai mata peljaran yang dianggap sulit, ditakuti dan kalau bisa dihindari oleh sebagian siswa. Padahal siswa seharus nya menyadari kemampuan berfikir logis, rasional, kritis, cermat dan efektif adalah menjadi ciri pengajaran matematika. Karena itu kreatifitas sebagai guru dalam mengajarkan matematika akan menjadi faktor kunci agar matematika menjadi pelajaran yang menarik didalam kelas, tidak lagi ditakuti dan dihindari. Untuk itu tujuan dari penelitian ini adalah bagaimana seorang guru bisa menjadikan siswa tertarik dalam mempelajarai matematika dengan cara memperbaiki cara pembelajaran, tekhnik mengajar dan lain-lain. Sehingga pada Kompetensi Dasar Menggunakan bentuk aljabar untuk memecahkan masalah, termasuk masalah aritmatika, akan lebih menarik dipelajari oleh siswa dan juga mudah dipahami. Selanjutnya kita akan tahu upaya untuk meningkatkan kemampuan dan kreatifitas dalam menyelesaikan soal cerita. Sedangkan siswa yang menjadi obyek penelitian adalah siswa kelas VII SMP Negeri 1 Mumbulsari. Dari hasil penelitian terungkap bahwa masih banyak siswa yang masih merasa kesulitan untuk menyelesaikan soal cerita. Sehingga penulis tertarik untuk menelitinya, dan ternyata faktor utamanya adalah terletak bagaimana cara kita kita menyampaikan dan memberi metode pengerjaannya, Agar mudah dipahami oleh siswa. Dengan menggunakan metode pemodelan Matematika akan mempermudah siswa mengubah bentuk cerita ke dalam kalimat matematikan dalam bentuk aljabar.

NILAI KETAKTERATURAN TOTAL SISI DARI GRAF TANGGA (STAIR GRAPH)
Get PDFAbstract. The total edges labelling λ is called an edge irregular total k-labelling of a graph G if every two distinct edges u and v in G ωt(u)≠ωt(v). The total edge irregularity strength of G is the minimum positive integer k for which G has a total edge irregular k-labelling. There are not many graphs of which their total edge irregularity strengths are known. In this article, we investigate the total edge irregularity strength of Stair Graph tes(Stn) and union of m isomorphic Stair Graphs tes(mStn).
Key Words: Total edge irregularity strength, Stair Graph (Stn)

Get PDFAbstract.The purpose of this researchis to helpsstudent to build their understanding about story termand up their problem solving. This research type of Classroom Actions Research (CAR) using Cooperative Integrated Reading and Composition model with Polya’s method in fraction operations at VII-D grade of SMP Negeri 2 Arjasa. The research has two cycleswhich has devising a plan, action, observation, and reflection for each cycle.Data collected by documentation, observation, test and interview method. The data observation showed increasing about teacher’s activity and student’s activity from 1st cycle to 2nd cycle. The student’s learning in 1st cycle showed that 29 students completed and 11 students not completed. So, the classical completion results that class uncompleted with percentage 72,5%. But the student’s learning result of 2nd cycle showed a good progress andclass completed with percentage 82,5%.
