Abstract

This study aims to determine the effect of group assignments on mathematics learning achievement in seventh grade students of SMP Negeri 8 Buton. This research is a quantitative research with a quasi-experimental method (quasi-experimental) carried out at SMP Negeri 8 Buton Tengah. The population in this study was class VII which consisted of 2 classes. The sample in this study were students of class VIIA as the experimental class and students of class VIIB as the control class, totaling 37 students. The instrument used in this research is a test of learning outcomes and documentation of learning outcomes. The results of the descriptive analysis were obtained: (1) the average initial test data for the experimental class mathematics learning achievement was 38.61, the final test data average for the experimental class mathematics learning achievement was 82.78 and the experimental class mathematics learning achievement increased 44.17 . (2) based on the results of hypothesis testing, it can be seen that tcount = 5.333 with df = 34 and significant (2-tailed) = 0.000 <0.05, so it can be concluded that H0 is rejected and H1 is accepted. So it was concluded that the use of the group assignment method had an effect on mathematics learning achievement in class VII students of SMP Negeri 8 Buton Tengah.

Abstract

This research aimed to determine the influence of mastery SPtLDV the ability to solve linear program questions for grade XI MIA SMAN 3 Baubau.This research was a quantitative research using ex-post facto method with simple regression analysis technique. Population in this research were 64 students of class XI MIA SMAN 3 Baubau in academic year 2020/2021. The sample in this research, the sampling technique used was the Cluster Random Sampling technique. Data collection was carried out by providing research instruments (test) to respondents to neasure students’ mastery of SPtLDV material in solving linear program questions. The results of the research were then analyzed using descriptive analysis and inferential analysis in the form of t-test. Based the results of analysis, it concluded that: 1)mastery of SPtLDV concept of grade XI MIA SMAN 3 Baubau obtained average value 50.85,percentage of 65%, this showed value in high category, namely 13 of 20 students. 2)The level of students’ ability in solving the linear program questions of XI MIA SMAN 3 Baubau obtained an average value 53.20,percentage of 65%, this showed value in high category, namely 13 of 20 students, and 3)based on the results of simple linear regression analysis, it is obtained tcount(t0)=4.666 and ttable=2,101. It meant is tcount>ttable (4.666>2.101),then and H0 was rejected and H1 was accepted, so that it was conclude that: there was effect of mastery SPtLDV concept on the ability to solve linear program questions for grade XI MIA SMAN 3 Baubau by 54.7% while 45.3% influenced by other variables not included in this research.

Abstract

The purpose of this research is to know about the improvement of the mathematical problem-solving ability of grade VII students through the application of creative problem-solving model based on contextual. This study included quasi-experimental. The population involves all students of class VII SMPN 2 Lapandewa consisting of three classes and samples taken by purposive sampling so selected 25 students from class VIIA as an experimental class and 25 students of class VIIC as a control class. The research instruments are pretest and postes problem-solving abilities. The data of the research were analysed using independent samples t-test. The result of the research shows that the improvement of mathematical problem-solving ability of students who follow creative problem solving based on contextual learning is better than who follow conventional learning. Thus this model can be used as an alternative effective learning model to improve students’ mathematical problem-solving skills optimally, especially on the rectangular material.

Abstract

The purpose of this research was to determine the effect of online learning on the interest in learning mathematics of SMA Negeri 1 Gu students. This research was a quantitative research using the Ex-post Facto method, where the research population was all students of class X SMA Negeri 1 Gu with a total of 248 students spread over 8 classes. The sampel used in this research was 25% of the population as many as 62 students. The instrument was questionnaire, this data was analyzed using simple linear regression analysis. The data of this study were obtained based on the results of inferential analysis by looking at the normality test, a significant value was obtained of 0.200> 0.05, the linearity test obtained a significant value of 0.283> 0.05, the autocorrelation test by looking at the dw value of 1.433 < du i.e. 1.6561 and less of (4 – du) 4 – 1.6561 and the heteroscedasticity test obtained a significant value of 0.586> 0.05. So it can be said that the data is normally distributed, linear, there are symptoms of autocorrelation and there are no symptoms of heteroscedasticity. By using simple linear regression the equation is obtained: Y = 28.922 + 0.727x. While the calculated F value obtained is 42.476 with a significant value of 0.00 <0.05. This shows that H0 is accepted, meaning that there is an effect of online learning on the interest in learning mathematics in X grade at SMA Negeri 1 Gu.

Abstract

The formulation of the problem in this research was whether there was an effect of self-confidence on the mathematics learning achiavements of VIII grade students of SMP Negeri 1 Buton Tengah?. The purpose of this research was to determine the effect of self-confidence on mathematics learning achievement of VIII grade students of SMP Negeri 1 Buton Tengah. This research was an ex-post facto research. The population in this research were all students of VIII grade as SMP Negeri 1 Buton Tengah which consisted of 5 classes. The sample was taken as much as 20% of the total population using random sampling tachniques at SMP Negeri 1 Buton Tengah. Data collection techniques in research used a questionnaire. Based on the result of calculations using simple regression, the linear regression equation was obtained: Y = 73.108 + 0.071X. with a t value of 0.528,it was significant at 0.602>0.05. This indicuted that H0 was accepted, or H1 was rejected. This meant that there was no effect of students self-confidence on students’ mathematics learning achievements at SMP Negeri 1 Buton Tengah.
