Abstract

Pengertian fungsi di kalkulus adalah pemetaan dari himpunan bilangan real ke himpunan bilangan real dengan fungsi jaraknya adalah nilai mutlak. Pada makalah ini akan disajikan pengertian fungsi dari suatu ruang metrik ke ruang metrik yang lain yang fungsi jaraknya mungkin saja berbeda. Selanjutnya akan dibicarakan mengenai limit fungsi pada ruang metrik, kekontinuan fungsi pada ruang metrik, fungsi kontinu seragam pada ruang metrik, kekompakan fungsi pada ruang metrik, dan teorema-teorema yang berhubungan dengan hal tersebut. Kata Kunci    : Ruang Metrik, Limit Fungsi, Fungsi Kontinu, Fungsi Kompak. Notion of a function in calculus is a mapping from the set of real numbers to the set of real numbers with absolute value it is. On this paper will be presented the notion of functions of a metric space into the other metric space with the functions of the distance is probably different. Next will be discussed regarding the limit of a function on a metric space, the continuous function on metric spaces, uniform continuity on the space metric, a metric space compactness function and theorems that relates to it. Key words     :  Metric Space, Limit Of The Function, The Continuous Function, Compact Function.

Abstract

Learning mathematical analogy is one alternative learning that can be applied in order to cultivate the power of reason (power of reason) students. Through mathematical analogy students are required to be able to look for similarities or relationship nature of the two concepts are the same or different by comparison, then draw a conclusion from the similitude. Thus the analogy can be used as an explanation or as the basis of reasoning. Before starting the analogy of learning mathematics, teachers should examine the ability of understanding mathematical concepts of students, because of the level of understanding of students will affect the power of reason. Tasks (problems) mathematical analogy included non-routine matter, therefore the required readiness of teachers to make it. In each question contained mathematical analogy same or different concepts, so it takes quite a lot of material. Steps to make about the mathematical analogy, are: a) assemble all the concepts in mathematics student has learned; b) Similarly stacking properties / relationships contained in any concept, and c) select materials that have a nature / relationship analogous. In this paper is given two forms of matter of mathematical analogy is the analogy of mathematical models and mathematical analogy 1 models 2. Learning mathematical analogy should be carried out after a number of concepts learned. It is better to be given in classes end for many of the concepts that have been learned by the students. Reasoning power (power of reason) the student becomes an important part in the process of learning to drive them toward their future as citizens are intelligent, which will be led by the power of reason (the brain) and not by the strength (muscle) only. As noted by former US President Thomas Jefferson (in Copi, 1978: vii), which states: "In a republican nation, Whose citizens are to be led by reason and persuasion and not by force, the art of reasoning Becomes of first importance"

Abstract

Kemampuan seorang guru dalam menggunakan kegiatan khusus di dalam kelas (misalnya membentuk kelompok kerja, praktik menghitung secara mental/tanpa alat hitung, pengajaran langsung atau metode lainnya) merupakan hal yang penting, tetapi keyakinan yang meliputi pemahaman terhadap kematangan dan kesiapan siswa dalam proses belajar juga memiliki kedudukan strategis. Psikologi pembelajaran akan membantu guru dalam mengungkap potensi yang dimiliki siswa dengan tidak melupakan hakikat siswa sebagai manusia yang memiliki jati diri yang berhak diakui eksistensinya dan berbeda satu dengan lainnya. Pembelajaran sebagai proses yang dilalui siswa, tidak dapat dipisahkan dengan perkembangannya. Seorang guru yang professional, tidak akan memandang proses belajar pada siswa tanpa memandang perkembangannya. Dengan memperhatikan perkembangan siswa, maka proses belajar akan terjadi sesuai dengan kesiapannya.Kata Kunci : Psikologi Pembelajaran, Kualitas Lingkungan Belajar Matematika  The ability of the teachers to use the special activities in the classroom (eg, forming learning groups, practice counting mentally/without a calculator, direct instruction or other method) is important, but the belief that includes an understanding of the maturity and readiness of students in the learning process as well has a strategic position. Psychology of learning will help teachers to uncover the potential of students by not forgetting the nature of students as human beings who have a right to be recognized identity and existence distinct from one another. Learning as a process through which students, can not be separated with the development. A professional teacher, will not look at the students' learning process regardless of its development. Having regard to the development of students, the learning process will take place in accordance with readiness.Key words : Psychology of Learning, Learning Mathematics Environmental Quality

Abstract

This research uses experimental method pretest posttest disign. The purpose of this study was to determine the increase in the confidence of students in mathematics in mathematics learning with metaphorical thinking humanist. This research was conducted at the Junior High School level. The instrument used in this study is the achievement test and questionnaire about students' confidence. The results showed that mathematics humanists with metaphorical thinking (MT) is superior to conventional learning in enhancing the confidence of students, viewed as a whole and based on the level of the school and the beginning of students' mathematical abilities. There is a high association between KAM and confidence in the classroom with learning metaphorical thinking, and the conventional class association between KAM and confidence quite enough. The confidence of students whose learning approach metaphorical thinking (MT) is better than using the normal way (CB), students gain confidence to approach learning MT and CB are in qualifying was.
