A Pedagogical Value From Mathematical Mistakes
A real correct and mistake basically have the same point. Mistake done by student during doing mathematics problem can have the positive values and worth to develop the new mathematics concept. In mathematics teaching, process to understand a concept sometimes will be easier if besides gave a lead real correct and also accompanied by the counter of example from looking the aspect of mathematics mistake good for student and to learn in developing values pedagogic such thinking critical, logical, analytical in exploring to born the new mathematics. We often dismiss a mistake as something to be avoided and at best to be corrected as soon as possible. Many types of algebraic mistakes and purely arithmetic ones and discusses how they can be channeled into positive, useful learning, and growing experience. Mathematical Mistake can be used as a springboard for developing new mathematics and can be use to turn negative experiences into positive ones.
Key Words: Mathematical Mistake, Pedagogical Value
The Use Of Coastal Potency In Learning Mathematics To Enhance Social Skills Of Junior Secondary School Students
Social skills of junior secondary school students in coastal area are still considered low due to the lack of interaction in mathematics learning. Interaction in coastal class can be done by using coastal potency problem. The objective of this study is to enhance students’ social skills by using coastal potency in learning of mathematics (CCTL). Junior secondary school sample is randomly selected from 10 classes in SMPN 5 Kendari. Two classes are randomly selected from the school sample, experiment class (CCTL) and control class (conventional teaching and learning, CVTL). Instrument that was used in this research is scale of social skills. Data are analyzed by using a qualitative-descriptive technique, one-sample T test, and independent-sample T test. Based on the result of data analysis, it can be concluded that the use of CCTL is significantly better than CVTL in enhancing the students’ social skills, however it’s still in the medium category.
Keywords: coastal potency, social skills, coastal potency-based contextual teaching and learning (CCTL
The Implementation Of Multiple Intelligences Based Learning To Improve Students’ Learning Activities, Response, And Learning Outcome In Mathematics
The fundamental basic theory of this study comes from Howard Gardner, who introduced a theory of human intelligence known as the Multiple Intelligences Theory. This theory concludes that there are eight types of intelligence which belongs to each person. The purpose of this study was to find out the implementation of multiple intelligences based learning to improve students’ learning activities, response, and learning outcome in mathematics. This research was conducted in SMP PGRI 1 Ciputat in academic Year 2009/2010. This research used Classroom Action Research, which consists of four stages research procedures were planning, action, observation, and reflection. The instruments of collecting data were using observation sheet activities, daily student journals, interview, and test. The result of the research revealed that the implementation of Multiple Intelligences based learning can enhance mathematics learning activities, giving a positive response towards mathematics and to improve student learning outcomes.

Upaya Menumbuhkembangkan Kemampuan Berpikir Kreatif Siswa dalam Pembelajaran Matematika: Systematic Literature Review
Kemampuan berpikir kreatif merupakan kemampuan yang perlu terus diasah pada peserta didik khususnya pada pembelajaran matematika. Metode penelitian yang digunakan pada artikel ini yaitu metode Systematic Literature Review (SLR). Hasil penelitian menunjukkan bahwa upaya perwujudan peningkatan kemampuan berpikir kreatif siswa dalam pembelajaran matematika dengan menerapkan berbagai skema pembelajaran misalkan model, pendekatan, strategi atau penggunaan media pembejaran untuk menstimulasi kemampuan berpikir kreatif siswa yang lebih baik. Sebagian besar upaya peningkatan kemampuan berpikir kreatif siswa dalam pembelajaran matematika terbukti efektif. Beberapa tantangan dalam usaha mengembangkan kemampuan berpikir kreatif siswa yaitu penerapan skema pembelajaran yang memerlukan waktu yang relatif lama, siswa perlu beradaptasi dengan skema pembelajaran baru; tingkat kemampuan siswa yang bervariasi; siswa yang masih pasif dalam pembelajaran; skema pembelajaran yang hanya cocok pada topik tertentu; peralatan dan media pembelajaran yang masih kurang memadai; rendahnya minat belajar siswa; dan siswa belum terbiasa menyelesaikan soal kemampuan berpikir kreatif
Analisis kemampuan berpikir kreatif calon guru sekolah dasar dalam menyelesaikan soal pecahan
Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kreatif matematis pada aspek fluency, flexibility dan originality dalam menyelesaikan soal pecahan. Subyek penelitian adalah mahasiswa semester V pada Prodi PGMI IAIN Manado, Sulawesi Utara, Indonesia. Pengumpulan data dilakukan dengan tes, wawancara, dan dokumentasi. Metode validasi data menggunakan triangulasi, yaitu teknik dan sumber. Teknik analisis data menggunakan metode interaktif yang terdiri dari reduksi, penyajian, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa aspek fluency dicapai mahasiswa berkemampuan tinggi dan sedang karena dapat menggambarkan beragam persegi panjang yang diminta soal dengan benar. Kemudian, aspek flexibility hanya dapat ditunjukkan oleh mahasiswa berkemampuan tinggi karena dapat menentukan alternatif lain untuk menentukan potongan kue mana yang lebih besar. Aspek originality tidak dapat ditunjukkan oleh mahasiswa karena jawaban yang dihasilkan cenderung sama. Dengan demikian, mahasiswa dengan kemampuan berbeda-beda memiliki pemikiran kreatif yang berbeda pula

With diversity of functions, academic digital library is seen the most awaiting proxy in
changing the information culture among academic users. This paper in general attempts to highlight the phenomena of using digital library system in public universities in Malaysia. The focal of the discussion is on digital reference services of academic digital library
A Model of Plant Identification System Using GLCM, Lacunarity And Shen Features
Recently, many approaches have been introduced by several researchers to
identify plants. Now, applications of texture, shape, color and vein features
are common practices. However, there are many possibilities of methods can be
developed to improve the performance of such identification systems. Therefore,
several experiments had been conducted in this research. As a result, a new
novel approach by using combination of Gray-Level Co-occurrence Matrix,
lacunarity and Shen features and a Bayesian classifier gives a better result
compared to other plant identification systems. For comparison, this research
used two kinds of several datasets that were usually used for testing the
performance of each plant identification system. The results show that the
system gives an accuracy rate of 97.19% when using the Flavia dataset and
95.00% when using the Foliage dataset and outperforms other approaches.Comment: 10 page
