Abstract

Abstract. The purpose of this research was to investigate the effect of interactive media to support the effectiveness of thematic learning in elementary schools. This research was an experimental method with one group pretest posttest design. The sample of this research was second grade students of three schools such as SD YPK Mopah Lama, SD Wasur II and SD Theresia Buti Merauke. The number of students was 42 students. The results of data analysis revealed that there was a significant effect on the improvement of thematic learning by applying interactive media, as evidenced by the value of tcount> ttable (3.656> 1.845). Based on the experimental results, there was an increase of 2.476 or 6.11%. Furthermore, based on the effectiveness of the applying of interactive media was in the good category. Keyword: interactive media; thematic learning Abstrak.

Abstract

This study aims to find out the first, the effectiveness of SAVI learning approach in mathematics learning of students of Muhamadiyah Merauke. The second, the effectiveness of contextual approach used in mathematics learning viewed from mathematics learning achievement of students of SMP Muhammadiyah Merauke. And the third, the comparison of effectiveness between SAVI learning approach and contextual method viewed from of learning achievement in mathematics. This research is an experimental research and the design used pretest-posttest control group design. The population of this research is grade VIII B students of SMP Muhammadiyah Merauke selected by cluster random sampling technique. The technique of data collection was test and the instrument was learning achievement test. The testing of first and second hypothesis used paired sample of z-test while the third hypothesis testing was done using independent sample of z-test. Based on the analysis of the first hypothesis data, it was obtained, which means thatis rejected and is accepted. This means that the SAVI learning approach is effectively used in learning in terms of students' mathematics learning achievements. Analysis of the second hypothesis data, it was obtained, which means that is rejected and is accepted. This means that the contextual learning approach is effectively used in learning in terms of students' mathematics learning achievements. Then the third hypothesis data, the comparison of mean of posttest data was obtained, which means thatis rejected andis accepted. This means that the SAVI learning approach is more effective than contextual learning approaches in terms of students' mathematics learning achievement.

Abstract

This research is a quantitative descriptive research that aimed to discover the external factors affecting students in doing Mathematics Homework and to discover the most dominant external factors. The sample used in the research represented the entire population of sixty students. Data collecting techniques used is by distributing the questionnaires. The questionnaire contained nine external factors was tested for validity and reliability. Data analyzing technique used is descriptive analysis technique. The result of this research is nine external factors affecting the students of Madrasah Al-Munawwaroh in doing the Mathematics homework they are factor of follow up of the teacher in giving Mathematics homework as 97.5%, factor of giving the value of Mathematics homework as 98.33%, factor of type and nature of Mathematics homework as 81.67%, factor of responsibility and time to do the Mathematics homework as 85%, factor of the Mathematics homework difficulty level as 81.67%, factor of material and resources in doing Mathematics homework as 88.83%, factor of teaching method and Mathematics teacher characteristics as 90%, factor of friend influenced as 85%, and parents support as 72.5%. The dominant external factors are the factor of giving value in Mathematics homework, the factor of follow up of teachers in the giving Mathematics homework, and factor of how to teach and Mathematics teacher characteristic. Keywords: external factor; mathematic; homework.

Abstract

Abstract: This study aims to develop discovery learning student worksheets in class VIII of SMP Negeri 4 Kurik and to improve the ability to think creatively in mathematics learning for material in Two Variable Linear Equation Systems (SPLDV). The instrument of data collection in this study is a matter of pre-test and post-test, questionnaire, observation and documentation. This type of research uses development research, research design using the model of Analysis, Design, Development, Implementation, Evaluation (ADDIE), the subject of research is VIIIA grade students of SMP 4 Kurik. The object of the research is student worksheets with the subject matter of two-variable linear equation systems. Development research methods, including research design, research sites, subjects, data sources, data collection techniques, research instruments and data analysis techniques using tabulation data to determine the increase after and before using student worksheets. The results of the study and conclusions obtained the level of mathematical creative thinking of class VIIIA students of SMP N 4 Kurik after being tested on this student worksheet of 92.19% with a level of creative thinking in the aspect of fluency of 90.63%, aspects of flexibility 95.83%, aspects of authenticity of 92 , 71%, and detail aspects 89.58%.
