Abstract

The problems that were examined in this research relate to learning about mathematics students who is still low. For that reason it is , the purpose of this study is to find an increase in the results of the kind of classroom learning about mathematics through question student have to their students odd semester class viii junior high school Al Azhar 3 Bandar Lampung in year 2018/2019. The research is research class action ( ptk ) on a student viii a junior high school al azhar 3 lampung consisting of 32 students. To know the results the students learn math test luminance the cycle in the form of essai 5 about as many as with an indicator of success when 75 percent the number of students reach kkm = 70. Any test had first tested the validity of and reliabilitasnya , so they could be used as a measuring instrument research. From the test every cycle it is apparent that an increase in the pre learn math students from research to cycle I of 25 % (56 % students completed kkm) and The first cycle to cycle II of 25 % (81 % students completed kkm). Thus indicators finish in the research success in cycle II. So we can conclude that “an increase in the students learn math through learning model question student have on students VIII in the odd semester class viii junior high school Al Azhar 3 Bandar Lampung in year 2018/2019.

Abstract

The problems that were examined in this research pertaining to less account of the results that students are learning mathematics. The purpose of this research is to find the learning strategy guide prediction for the students learn math ability of class VIII of SMP UTAMA 3 Bandar Lampung in the academic year 2018/2019. The research uses experimental methods to the population in this research is all students ability of class VIII of SMP UTAMA 3 Bandar Lampung, its consisting of 3 class to the total number of 83 students, The sample was taken two classes viii-b class as a class the experiment apply prediction guide strategy And viii-c class as a class control a conventional learning. Sample taken using a technique clusters of random sampling. To know mathematics students writer test in the form of an essay as many as 10 the first has been tested validity and reliability. The testing of hypotheses on this research using formulas t-hit. The results of the testing of hypotheses using formulas statistic t-hit = 9,40 obtained the t. From table distribution t on significant standard known t = 5 % = 2,00 then so which means the average learning outcomes mathematics students who use prediction guide strategy be higher than the average learning outcomes mathematics students who use conventional kind of classroom From the above it can be concluded guide prediction that strategy can and have had a positive impact of the results of learn math.

Abstract

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.

Abstract

The problem in this study is the low ability of students' mathematical communication in learning. The purpose of this study was to determine the effect of using android-based learning media on the mathematical communication abilities of Class VIII students in Odd Semesters of SMP Negeri 13 Bandar Lampung in the Academic Year 2022/2023. This study used an experimental method with the population in this study, namely all students in class VIII Odd Semester SMP Negeri 13 Bandar Lampung. The samples used in this study were two classes, namely class VIII-4 as the experimental class, and class VIII-3 as the control class. Samples were taken using the Cluster Random Sampling technique. To find out students' mathematical communication skills, a test was carried out in the form of an essay of five questions which had previously been tested for validity and reliability. Hypothesis testing in this study uses the t_hit formula. From the results of testing the hypothesis using the t_hit statistical formula, the value of t_hit = 4.04 is obtained. From the t distribution table at a significant level of 5% it is known that t_daf = 1.67, then t_hit>t_daf, which means that the average mathematical communication ability of students using Android-based learning media is higher than the average mathematical communication ability of students using conventional approaches.
