Abstract

The purpose of the research for to know the difference mathematical generalization ability of student are taught by use guided discovery learning and expository. The research was held at SMPN 21 Bekasi in second semester academic year 2016-2017. The sample is class VII.2 and VII.5 (76 students). This research used quasi-experimental with statistic group comparison or post-test-only with nonequivalent groups design. Instrument be used is an essay test to measure mathematical reflective thinking ability. Before tested instrument analyzed by correlation product moment to test the validity, reliability by formula alpha cronbach and an index of the lurch. The data is analyzed firstly be done test regulation is test normality with Lilliefors and also test homogeneity by using Fisher. The result of normality test of class experiment and control can be conclude that both of the sample are from normal distribution. While the result of homogeneity test can be conclude the population of both have a homogeneity variance. The result of research were obtained t result is 5,29 with significance ? is 0,05. The result of research showed a difference mathematical generalization ability of student through guided discovery learning and expository.

Abstract

The role of parents is needed in the education of children. The role of parents in education makes the quality of children's education better. The purpose of the study was to determine the relationship between the role of parents and the mathematics learning outcomes of Algebra during the Corona Virus Disease 2019 (COVID-19) Pandemic. The research sample was 72 junior high school students in class VII. This study uses quantitative methods with survey techniques. The instrument is a questionnaire and an objective test. The prerequisite test used the Liliefors test, and the data were normally distributed. An analysis of the regression equation shows there is a positive relationship between the two variables. Hypothesis testing using the product-moment correlation test is obtained rcount more than rtable at a significant level of 5%. Because rcount more than rtable, it can be concluded that there is a strong relationship between the role of parents and learning outcomes in mathematics. Based on the correlation t-test, obtained tcount>ttable with db=70. The conclusion is that there is a significant positive relationship between the role of parents and the mathematics learning outcomes of junior high school students. Parents' attention contributes 57.15% to mathematics learning outcomes.
