PEMAHAMAN GEN Z TERHADAP SEJARAH MATEMATIKA
Full text linkThe purpose of this study was to determine the extent of generation Z's understanding of the history of mathematics. The population of this study was students of the Indonesian Teknokrat University Mathematics Education class of 2017 and 2018 who had taken philosophy and history of mathematics courses. Subject selection is done by the saturated sampling method, where the number of samples used is the same as the population. The sample used is still classified as generation Z because it was born in 1998-2001. This research is a qualitative descriptive study with data collection techniques using a questionnaire containing 20 questions. From the research results, it is stated that the history of mathematics is very important to be applied and integrated into the mathematics learning process. This can be shown by obtaining the percentage of achievement of the indicators in positive questions of 75%. The understanding of the history of mathematics according to generation Z, namely 74% can foster enthusiasm, skills, and confidence in the learning process, 84% can be used as a strategy in the learning process, 74% increase motivation to explore mathematics, 68% can compare mathematics with ancient techniques and current techniques, 58% can know more or less the origins of mathematics and 84% know more about the character behind the formulas used in mathematics. However, as many as 53% of generation Z still have a low interest in the history of mathematics and 63% of generation Z give an opinion that the history of mathematics does not change their impression that mathematics is scary.Keywords: generation z; history of mathematics; understandingDOI: http://dx.doi.org/10.23960/mtk/v9i2.pp116-12
PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK MATERI KELILING DAN LUAS BANGUN DATAR MENGGUNAKAN KALKULATOR DENGAN PEMBELAJARAN DELIKAN
Full text linkThis research is a research development (Research and Development) that aims to determine the feasibility of LKPD Mathematics products as well as the supporting and inhibiting factors of using LKPD. This study uses the Borg and Gall development model. The instruments used were tests, interviews, and questionnaires. There are 3 types of questionnaires used, namely expert validation questionnaires, student response questionnaires, and teacher response questionnaires. The results of the validation that have been carried out by the three validators obtained an overall average value of 4.16 with valid criteria. The LKPD trials were carried out by the Delikan learning steps (listen, see, and do). The average score of the students' questionnaire response was 4.58 with very good criteria. The teacher response questionnaire to the mathematics LKPD obtained a result of 4.2 with a good category. The use of LKPD received a very good response from students because the use of calculators was something new, but some students did not understand the concept of multiplication and long division so they needed guidance from the teacher. LKPD Mathematics of the circumference and area of a flat shape using a calculator with Delikan learning in Class IV SD UMP is said to be feasible and can be used as an alternative teaching material to improve skills in calculating the circumference and area of a flat shape using a calculator calculating tool.Keywords: calculator; delikan learning; mathematic; student worksheet activity (LKPD)DOI: http://dx.doi.org/10.23960/mtk/v9i2.pp85-9

IMPLEMENTASI DESAIN DIDAKTIS KONSEP PROGRAM LINEAR DALAM MENGATASI KESULITAN BELAJAR SISWA
Full text linkOne way that can be done in overcoming these students' learning difficulties is by making improvements related to the teaching materials presented. This is done so that students can understand the concept of linear programming that is not textual. Therefore, this research was developed to develop a design of teaching materials (didactic design) that is more relevant for students so that students' learning difficulties can be overcome. Abstract is different from summary. The research method used is qualitative research methods with design research using Didactical Design Research (DDR). The subjects in this study were 37 high school students in class X in one of the schools in Kabupaten Cirebon. This study has three important stages, namely, preparing ADP, metapedadidactic analysis, and retrospective analysis. The results obtained in this study are that the didactic design was developed with four didactic situations to solve students' difficulties in determining the optimum value of the problem using the test point method and the probing line method.
