Abstract

Penelitian ini bertujuan menghasilkan lintasan belajar yang dapat membantu siswa memahami konsep bentuk pangkat melalui konteks perkembangbiakan hewan secara vegetatif. Design Research dipilih sebagai cara yang tepat untuk mencapai tujuan. Lintasan belajar (Hypotetical Learning Trajectory) dalam design research memegang peranan penting sebagai desain dan instrumen penelitian. Lintasan belajar dirancang dalam tahap desain awal dan diujikan pada 50 siswa kelas IX (yaitu, 6 siswa pada pilot experiment dan 44 siswa pada teaching experiment) SMP YPI Tunas Bangsa Palembang. Hasil dari percobaan pembelajaran menunjukkan bahwa aktivitas menggambar proses perkembangbiakan hewan secara vegetatif dapat mendorong siswa untuk melihat bentuk penggandaan yang terjadi, dan ketika siswa melihat penggandaan melalui pemodelan (bagan/skema) yang siswa buat, siswa memiliki ide untuk menghitung hewan baru yang terbentuk kemudian menggunakan bilangan kelipatan untuk menentukan banyak hewan baru. Dari bilangan kelipatan, ide untuk menyatakannya kedalam bentuk perkalian berulang membawa siswa ke dalam definisi bentuk pangkat.This study aims to produce a trajectory of learning that can help students understand the concept of form promoted through the context of animal breeding vegetatively. Design Research chosen as the appropriate way to achieve the goal. Learning trajectory (Hypotetical Learning Trajectory) in design research plays an important role as design and research instruments. Tracks study was designed in the early design stages and was tested on 50 students of class IX (ie, 6 students in pilot experiments, and 44 students in the teaching experiment) SMP YPI Tunas Bangsa Palembang. Results of experimental study showed that the activity of drawing process animal breeding vegetatively can encourage students to look at the shape of doubling that to happen, and when students see a doubling through modeling (chart / schema) that students make, the students had the idea to calculate the new animal that is formed later use number multiples to determine a lot of new animals. Multiples of the numbers, the idea of putting it into the form of repeated multiplication bring students into the definition of the form of the rank.

Abstract

The research is purposed to generate a  learning trajectory that supports students to understand the concepts of exponential through the context vegetative propagation in animals. The Design Research was chosen as the exact method to achive the objective. Hypotetical learning trajectory in the design research played an important role as the design and research instrument. Hypotetical learning trajectory was designed as the preliminary design and was examined to 50 students from the ninth graders of YPI Tunas Bangsa Junior high school.  (e.g 6 students from pilot experiment and 44 students from teaching experiment). The result of the learning experiment showed that drawing activity of the process of animal vegetative propagation could motivate the students to see the form of the animal multiplication. While seeing the animal multiplication through modeling (scheme, chart, and diagram), the students had an idea to calculate new animals had been formed, and used multiple numeral to determine the sum of the new animals. From the multiple numeral, an idea to state it in terms of repetitive numeral would bring the students into a definition of exponential. Based on the result above, its suggested that context containing multiplication form be used, let the students see multiplication, and the students do it mathematically into the basic concept when they are learning exponential.
