Abstrak: Penelitian ini merupakan penelitian Eksperimen semu yang bertujuan untuk mendeskripsikan hasil belajar siswa SMP Negeri 13 Makassar yang diajar dengan menggunakan Model Kooperatif Tipe Snowball Throwing dan Metode Ekspositori, serta untuk mengetahui apakah model pembelajaran kooperatif tipe Snowball Throwing efektif digunakan dalam pembelajaran matematika pada siswa kelas VIII SMP Negeri 13 Makassar. Luaran yang akan dihasilkan dari penelitian ini adalah penerapan alternatif pembelajaran yang tidak monoton sehingga dapat meningkatkan hasil belajar matematika siswa dan perangkat pembelajaran (silabus dan RPP) yang berorientasi pada pembelajaran koperatif tipe Snowball Throwing. Subjek penelitian dibagi dalam 2 kelompok, yakni kelompok eksperimen yang diajar dengan menggunakan pembelajaran kooperatif tipe Snowball Throwing dan kelompok kontrol yang diajar dengan menggunakan metode ekspositori. Setiap kelompok diajar dengan frekuensi pertemuan yang sama dengan materi yang sama. Hasil penelitian menunjukan bahwa penerapan model pembelajaran kooperatif tipe Snowball Throwing lebih efektif jika dibandingkan dengan penerapan metode ekspositori untuk pokok bahasan sistem persamaan linear dua variabel. Kata kunci : Efektifitas Pembelajaran Matematika; Snowball Throwing;Metode Ekspositori.Abstract: This experiment research aims to describe the learning outcomes of students at SMP Negeri 13 Makassar taught with snowball throwing (cooperative) and expository method, and to find out whether snowball throwing method is more effective in learning mathematics than expository method in grade 7. The results of this research are implementing alternative learning method which is not monotonous to improve students' mathematics learning outcomes and producing learning tools that consist of syllabus and lesson plans based on snowball throwing method in cooperative learning. Research subjects are divided into two groups namely the experimental group taught with snowball throwing and the control group taught with expository method. Each group was taught with equal number of
This research is a quasi-experimental study which aims to describe the effect of cooperative learning type Think Pair Share (TPS) on students' mathematical communication skills, and to find out the percentage of students' activeness in participating in learning and knowing students' positive responses to learning. The output that will be generated in this study is that students can be more active in the learning process, more active in solving mathematical problems, and can be more confident in expressing their answers in public so that after applying cooperative learning models the Think Pair Share (TPS) mathematical communication skills of students will be better. The research subjects were divided into 2 groups, namely the experimental group taught using the cooperative learning model Think Pair Share (TPS) type, and the control group taught using Conventional learning models. Each group is taught with the same frequency of meetings with the same material. The results of the study show that the application of the cooperative learning model Think Pair Share (TPS) influences students' mathematical communication skills
This research aims to the Number Generalization process based on APOS Framework (action, process, object, and schema). Furthermore, the research is explorative research with a qualitative approach. The subjects of the study were one of the junior high school students who won the provincial mathematics Olympiad in South Sulawesi, Indonesia. Subjects were given instruments that had been developed, namely the number patterns generalization test. Data collection of this study is the number patterns generalization test and in-depth interviews. The data analysis process was reducing, describing, validating, and concluding. The results showed that the students who won the Olympics in the action stage determine the next term, if given a sequence by using a number pattern. At the stage of the process, action interiorizing by calculating the value of the next term repeatedly and explaining the process of determining the next term. At the object stage, encapsulating the process by showing that a number pattern has certain characteristics, de-encapsulating by assessing the observed pattern, and checking the number pattern found. At the schema stage, explaining the generalization properties of number sequence patterns by linking the actions, processes, objects of a concept with other concepts, doing thematization by linking the existing concept patterns to the general sequence.
This study aims to describe the Generalisation Patterns Strategy of junior high school students based on gender. The subject of this study is two junior high school students in Makassar City, one male, and one female. Data collection techniques are written tests and interviews which used to obtain data about the strategy of the generalization patterns of students. The validity used time triangulation. The analysis data consists of three stages: reducing data, presenting data, and daring conclusions. The results of this study show that the male subject used the strategy of Counting, Whole-object-No Adjustment, and Difference-Rate Adjustment. Meanwhile, the female subject used the strategy of Countin and Explicit in the generalization of patterns on numbers and pictures.
