Peningkatan Hasil Belajar Matematika melalui Pembelajaran Kooperatif Group Investigation pada Siswa Kelas VII SMP Negeri 15 Bulukumba

This research is Classroom Action Research which aim to increase student\u27s learning result. The research\u27s subject is students of VII SMPN 15 Bulukumba year 2011/2012 with the student amount 33 people. The data collect by using observation and result of mathematics test in the first cycle and second cycle and qualitative data is student observation result. The result of the research point out with: 1) Student activity and student response in Cooperative Teaching Type Group Investigation is increased. 2) Cooperative Teaching Type Group Investigation can improve learning mathematics at class VII SMPN 15 Bulukumba 3) the result of learning mathematic at cycle one with average score 56,72 of score ideals 100 with standard deviation 18,00 in low categorize increased in cycle two with average score 75,36 of score ideals 100 and standard deviation 14,65 in high categorize

Penerapan Model Pembelajaran TGT dengan Alat Peraga Ultaphygo untuk Meningkatkan Hasil Belajar Matematika Siswa

This research is a classroom action research with the aim of knowing the improvement of student mathematics learning outcomes throught the application of the TGT learning model with Ultaphygo teaching aids. This research includes planning, implementing, observing, and reflecting. motivated by the low learning outcomes of students at SMK Mega Link Majene in mathematics. The research subjects were students of class X SMK Mega Link Majene. Data collection techniques used student activity observation sheets, learning implementation observation sheets, and student learning outcomes tests at the end of each cycle. Each data collected at the end of the cycle was analyzed quantitatively by using descriptive statistics for student learning outcomes, while student activity and learning implementation used qualitative analysis. The results showed an increase in student learning outcomes from pre cycle to first cycle. This can be seen in the average student learning outcomes in the pre-cycle test results of 78.34, then an increase in the first cycle with an average student learning outcomes of 87.66 with a completeness percentage of 89.05% of 37 students. Likewise, student activity also experienced an increase from pre-cycle an average of 78% to an average of 93% in the first cycle with the very good category. Based on the description, it can be concluded that there is an increase in the learning achievement of students' mathematics learning activities through the application of the TGT learning model using Ultaphygo teaching aids
