In addition, conventional learning methods that characterized by lectures were still often used by teachers in learning. Therefore, the learning not being more active, effective, and enjoyable. The development of educational learning media like analog clock board was one of the solutions to improve students’ understanding. This research aims to determine the effectiveness of analog clock board as learning media to solve mathematics learning problems. The development model used was a 4D development research model. The results of media validation stated that analog clock board was feasible to be used in mathematics learning for angle measurement material. In addition, the results of the questionnaire shown that 90% of teachers and 100% of students stated the media was "very interested". The experiment results showed that analog clock board was more effective to improve students' understanding on angle measurement.</p>2020-05-11T06:45:24+00:00##submission.copyrightStatement##http://ejournal.iainkerinci.ac.id/index.php/edumatika/article/view/485 Pengaruh Blended Learning terhadap Kreativitas Mahasiswa Calon Guru di Universitas Negeri Medan2020-05-11T08:53:35+00:00Nurhasanah Siregarnurhasanahsiregar@unimed.ac.idSri Lestari Manurungsrilestarimanurung@unimed.ac.id<p>This study aims to determine the effect of blended learning strategies on the creativity of the pre-service teachers. By a quantitative approach, the type used in this study is a quasi-experimental with pretest-posttest control group design. The population in this study were pre-service teachers in semester VII of the Mathematics Education Study Program at Universitas Negeri Medan. The instrument has used a test in the form of essay tests of 5 items concerning creativity. The results of the study indicated that there were significant differences in the creativity of pre-services teachers who apply blended learning and direct learning. Thus, it could be concluded that blended learning gave effects of creativity.</p>2020-05-11T08:47:08+00:00##submission.copyrightStatement##http://ejournal.iainkerinci.ac.id/index.php/edumatika/article/view/500 Analisis Koneksi Matematis Siswa dalam Menyelesaikan Soal Setara TIMSS Ditinjau dari Locus of Control2020-05-14T08:41:59+00:00Nurul Auliyah Sutrisnonurulaulia1710@gmail.comDidik Sugeng Pambudididik@gmail.comRandi Pratama Martikusumarandi@gmail.com<p>This study aims to describe the students’ mathematical connections in terms of the locus of control. The mathematical connection indicators in this study are writing down the mathematical concepts that underlie the answers, recognize the relationship of various mathematical ideas and mathematical topics that can be related to problems of everyday life, and understand how to solve mathematical ideas that are interrelated and underlie each other to obtain an integrated whole. Data collection methods in this study were questionnaires, tests, and interviews. The subjects of this study were six seventh-grade students at MTs Negeri 7 Jember. The data analyzed by qualitative descriptive analysis. Based on the tests and interviews analysis, we known that students with internal locus of control could write mathematical concepts as a two variable linear equation system (TVLES). Students can connect TVLES material with problems, for example, represented the object in variables x and y. Students can also solved the problems related to TVLES material by using common examples, elimination and substitution methods. While the students’ with external locus of control also can write the mathematical concepts as a TVLES. But the students did not write in detail the relationship between TVLES material and the problem. Students can not solve problems by using TVLES solutions such as elimination and substitution, but students only use estimates in finding solutions.</p>2020-05-14T05:51:32+00:00##submission.copyrightStatement##http://ejournal.iainkerinci.ac.id/index.php/edumatika/article/view/442 Perbandingan Kemampuan Representasi Matematis Siswa Sekolah Dasar pada Penggunaan Media Pembelajaran Augmented Reality dan Pasir Kinetik2020-05-16T18:39:21+00:00Nurbaiti Widyasarinurbaiti.widyasari@umj.ac.idIsmawati Ismawatiismawati@umj.ac.id<p>This study aims to determine the difference of students’ representation ability through the Augmented Reality (AR) and kinetic sand as learning media. This research is a quasi-experimental by nonequivalent control group design. The students’ representation ability compared based on students’ prior mathematical ability (PMA) as high, medium, and low category. The data analyzed by using two path Anova on SPSS 16. The results of data analysis shown that there is no difference on students’ representation ability in both AR class and kinetic sand class in significance value of 0.68. In addition, there is no interaction between AR media and kinetic sand in significance value of 0.542.</p>2020-05-15T09:47:44+00:00##submission.copyrightStatement##http://ejournal.iainkerinci.ac.id/index.php/edumatika/article/view/525 Pengembangan Perangkat Pembelajaran Aljabar Berbasis Problem Based Learning untuk Mendukung Kemampuan Komunikasi Matematika Siswa Sekolah Menengah Pertama2020-05-16T18:31:17+00:00Sri Winarnisri.winarni@unja.ac.idMarlina Marlinamarlina@unja.ac.id<p class="abstract">The purpose of this research is to develop learning tools based for Algebra on Problem Based Learning (PBL) to support the mathematics communication ability of Junior High School students. Learning tools developed in this development research is students’ worksheets. The research method used is 4D model, which consists of 4 stages, namely define, design, develop, and disseminate. The results of worksheets’ validation by experts were 4,05 for the layout design and 4,19 for the content (both were categorized as valid). In addition, the students respons that the students’ worksheets were practical (with average of 3,94) and the teacher responses that these were very practical (with average of 4,23). Thus, based on the expert validation as well as the students and teacher of mathematics responses, the learning tools developed have already met the criteria of valid and practical and ready for the field testing to see its effectiveness on students’ mathematics communication ability.</p>2020-05-16T18:20:08+00:00##submission.copyrightStatement##
