This research was conducted to enhance students' mathematics outcomes by using True Experimental research design with Pretest-Post-test Control Group Design. The collecting data technique used to pretest and post-test also students' and teachers' activity observation worksheet and students’ response questionnaire; all the instruments were analyzed using descriptive quantitative. The results show (1) based on t-test measurement, it is found that the average of the final score of the experimental group is better than the control group; (2) the most dominant on students’ activity is participating in problem-solving activities by discussing with groups with the result of 37%; (3) teachers activities score an average of 3.72 which means very good; (4) students indicate positive respond on learning with a score of 95.6%. So, it can be concluded that the reciprocal teaching approach assisted the wonder-share quiz creator which has a positive and significant effect.</p> Lala Anggraini Achmad Hidayatullah Endang Suprapti Copyright (c) 2020 INOMATIKA 2020-06-23 2020-06-23 2 2 126 135 10.35438/inomatika.v2i2.197 Tahap Preliminary Research Pengembangan LKPD Matematika Berbasis Konstruktivisme Materi Program Linier https://inomatika.unmuhbabel.ac.id/index.php/inomatika/article/view/195 <p>This research intends to lead an initial analysis in developing students' worksheets (LKPD) based on constructivism to facilitate the students’ ability in understanding the mathematical concepts optimally. This research used the Borg and Gall Model which consists of ten stages, but in this study conducted the first stages, preliminary research stage. The first step is the initial stage of the research; it needed analysis, students’ analysis, curriculum analysis, construct analysis, and analysis of existing teaching materials. Based on the results of the preliminary analysis, it can be concluded that to be able to fortify students’ ability in understanding the mathematical concepts, the teachers need learning tools that will help students learn and expand their skills in understanding mathematical concepts in the linear program material. The students’ worksheet, which is based on one of the methods that have been shown to enhance the ability to understand concepts, namely Constructivism, should provide information that will help students improve the ability to understand their concepts.</p> Rahma Oktaviani Zulfah Copyright (c) 2020 INOMATIKA 2020-06-24 2020-06-24 2 2 136 146 10.35438/inomatika.v2i2.195 Pembelajaran Materi Aritmetika Sosial Dengan Pendekatan STEM https://inomatika.unmuhbabel.ac.id/index.php/inomatika/article/view/191 <p>The social arithmetic skill of students in mathematics is still poor required practice in-class learning. One of them provides learning through STEM approach (Science, Technology, Engineering, and Mathematics). This research leads to describe the improvement of students’ learning outcomes in social arithmetic material through the STEM approach. The classroom action research method carried out in two cycles was used in this study due to an improvement in students’ social arithmetic skills. The subjects in this study were 41 students of grade VII who was studying social arithmetic material. Learning activities were designed through the STEM approach by giving project tasks in making fermented cassava and banana chips. Data collection in this study was conducted through a written test for cognitive assessment, while for the affective evaluation seen from the preparation until the final project assignments report. The data analysis of the test was measured using descriptive quantitative and the data observation was evaluated using descriptive qualitative. The findings show that the STEM approach allows students to grasp the social arithmetic material that can be seen from better learning outcomes from the research subjects.</p> Betty Heryuriani Musdayati Copyright (c) 2020 INOMATIKA 2020-06-24 2020-06-24 2 2 147 160 10.35438/inomatika.v2i2.191 Conjecturing Ability Dalam Pembelajaran Daring Masa Pandemi Covid-19 https://inomatika.unmuhbabel.ac.id/index.php/inomatika/article/view/201 <p>Learning was done online during the COVID-19 pandemic; it inhibits the development of mathematical cognitive abilities, whereas this ability supports the learning skills of students in mathematics. One of the cognitive gained is the conjecturing ability or the ability to formulate the mathematical conjecture of junior high school students. The conjecture is the reason that someone has a belief, interpretation of why a belief is true, or how someone knows what he knows. So it is necessary to do an in-depth study and analysis of students’ mathematical conjecturing abilities. This study involved 26 students in one of junior high school in Serang as the research subjects, the approach used is a qualitative approach. The finding shows that the students’ conjecturing ability is still worse in the category of students’ ability in making evidence to the solution, so it needs improvement from the poor of students’ mathematical conjecturing abilities.</p> Yani Supriani Giyanti Tb.
