Pengaruh Teknik Question Student Have terhadap Kemampuan Komunikasi Matematika Siswa Kelas VIII Semester Genap SMP Negeri 26 Bandar Lampung Tahun Pelajaran 2016/2017

The author in this study uses the experimental method, and data analysis uses statistical formulas. The population in this study were all class VIII semester even SMPN 26 Bandar Lampung consisting of 2 classes with a total of 242 students, while the sample was taken 2 classes namely class VIII.1 as the experimental class, and class VIII.2 as the control class. Samples were taken using simple Question Student Have techniques. To find out the mathematical communication skills students are given a test in the form of essays of 5 questions which have been tested for validity and reliability first. From the results of hypothesis testing using the t-hit statistical formula, the value t = 7.55 is obtained. From the distribution table t at a significant level of 5% it is known that t=t (1-α) = 2.00 thit>tdaf so it can be concluded that "There is the influence of the application of Question Student Have learning on mathematical communication skills of class VIIII students smester even SMPN 26 Bandar Lampung 2016/2017 academic year ".

Upaya Peningkatan Kemampuan Pemecahan Masalah Matematika melalui Creative Problem Solving pada Siswa Kelas VIII Semester Ganjil SMP Negeri 1 Bandar Lampung

The research problem is the low mathematical problem solving abilities of students. With this, the purpose of the study was to improve problem solving skills through Creative Problem Solving in the eighth grade students of the odd semester of SMP Negeri 1 Bandar Lampung. This research is a classroom action research (CAR). The research subjects were class VIIIB students of SMP Negeri 1 Bandar Lampung. The research data was taken using tests with indicators of success if 70% of students had passed the minimum completeness criteria or students had scored more than or equal to 70. From the results of the study the students' mathematical problem solving abilities in the first cycle were 60.98, in the second cycle of 70.74, and the third cycle of 77.97. Thus the completeness of students' mathematical problem solving abilities from cycle I to cycle II has increased by 9.76 and from cycle II to cycle III has increased 7.23. With this, it can be concluded that there is an increase in problem solving skills through Creative Problem Solving.

Pengaruh Model Pembelajaran Kooperatif Teknik Berkirim Salam Dan Soal Terhadap Hasil Belajar Matematika Siswa SMP

The problems discussed in this study are related to the low mathematics learning outcomes of students in class VIII of SMP Negeri 3 Trimurjo, Central Lampung. Based on this, this study aims to determine whether the cooperative learning model of Sending Greetings and Questions has an effect on the mathematics learning outcomes of eighth grade students of SMP Negeri 3 Trimurjo, Central Lampung. This research is using experimental method. The population in this study was class VIII SMP Negeri 3 Trimurjo Central Lampung which consisted of 3 classes with a total of 94 students and samples from each class amounted to 34 students as samples in the experimental class and 34 students as samples in the control class. Samples were taken using cluster random sampling technique. The instrument in this study used an essay test consisting of 10 items. The results of hypothesis testing using t-test and obtained thit = 9.48 and from the total distribution of t at a significant level of 5% it is known that t(1-α) = 2.00. It is proven that thit > tdaf so that it can be concluded that there is an influence of the cooperative learning model of the technique of sending greetings and questions on the Mathematics Learning Outcomes of Class VIII SMP students.
