Abstract

The general objective of this study was to find and analyze empirically the effect of the I Care learning model on the students' metacognition. The method used in this research was the experimental method. The affordable population in this study was grade X students of SMK Assyafiah which is located at Jalan Bukit Duri No.29, South Jakarta 2016/2017 academic year. The sample of the study was 60 students obtained through random sampling method that the researcher mixed in the population so that all subjects were considered the same. Data collection was done by documentation techniques (learning model variables) and test techniques (student metacognition variables). The collected data was then analyzed using the t-test. Before the data was analyzed, first descriptive statistical analysis and data requirements test (normality test, homogeneity test) were carried out. The results of the study showed that there was an influence of the I Care learning model on the students' metacognition. In other words, students' metacognition who used the I Care learning model was higher than the students' metacognition who used constructivism learning model.

Abstract

This study aimed to determine the effect of Macromedia flash learning on the mathematical concepts understanding. This experimental research was conducted at the SMP PGRI 20 JAKARTA in the academic year 2016/2017. The sample of the research was the students of class VII with the number of students as many as 56 students consisting of 28 students of class VII-2 as the experimental group and 28 students consisting of grade VII-3 students as the control group, with different treatment from each skill program. Research data from each group was obtained by posttest using an instrument in the form of 10 items about the form of description by fulfilling the assessment aspect for the concept comprehension ability. The instruments used in this study had been tested in advance and all items were valid and had a high degree of reliability. Data analysis of research results using t-test by first testing the assumption of normality and homogeneity. The results showed that there was a significant influence of Macromedia Flash learning on the mathematical concepts understanding, especially in triangle and quadrilateral materials in class VII SMP PGRI 20 JAKARTA

Abstract

The purpose of this study is to find out how effective the Realistic Mathematics Education (RME) approach is. The research method used in this study is the experimental method. The sampling technique uses simple random sampling technique. The instrument for collecting data in this study is an essay test consisting of 8 items. The data analysis technique used is the t-test, and based on the t-test calculation shows t-count = 10,098 and t-table = 2,002 at the significant level of 5% or (???? = 0,05) and the degree of freedom (dk = 58) which means t-count> t table (10,098> 2,002) then H0 is rejected and H1 is accepted. The conclusion is that the average mathematical problem solving ability of students given the Realistic Mathematics Education (RME) approach is higher than the mathematical problem solving abilities of students who are given an expository approach. And the effectiveness calculation for the Realistic Mathematics Education (RME) approach is quite high, which is 2,605. Thus, there is an influence and effectiveness of the Realistic Mathematics Education (RME) approach in the teaching and learning process.
