Abstract

This study aims to determine the results of initial observations regarding the material for sequences and series to students and teachers, to explain the identification of the need for Mathflash applications for sequences and series materials and to produce interactive media based on the Mathflash application for sequence materials. and sequences via a viable and effective App Inventor. The type of research used in this study is Research and Development (R & D). Researchers used the development method according to Borg and Gall with 8 stages of development, including: (1) initial observation; (2) plans; (3) making products; (4) product validation test; (5) limited scale test; (6) limited scale test revision; (7) field test ; (8) analysis of field results, with data collection techniques used are interview guidelines and expert questionnaires (observation sheets) and questionnaires for class XI students on a limited scale test, data analysis techniques used are qualitative and quantitative descriptive statistics with using the validity of the Aiken index. Then to analyze the effectiveness of the media with a posttest given to students. Based on the results of the media feasibility test, which was assessed by 5 experts, the overall average score of the three feasibility aspects was 3.53 in the eligible category, and the media assessed by 6 students got the overall average score for the two feasibility aspects of 4.54 in the eligible category. Testing the effectiveness of learning media using a one- sample t-test resulted in tobs = 5.574 and tc= 1.690. So, tobs > tc then reject Ho, so that interactive media based on the Mathflash application material is effectively used in learning.

Abstract

Pendidikan abad 21 menuntut guru untuk mengintegrasikan teknologi informasi dan komunikasi dalam proses pembalajarannya khususnya pembalajaran matematika. Namun, masih minimnya pelatihan, sosialisasi dan seminar terkait dengan cara mengintegrasikan teknologi informasi dan komunikasi yang valid, praktis dan efektif masih sangat kurang. Oleh karena hal itu, penelitian ini bertujuan menginvestigasi, menyusun strategi, mengimplemtasikan, dan mengevaluasi pelaksanaan pembelajaran daring guru matematika di masa pandemi COVID-19. Subjek penelitian yang terlibat pada penelitian ini adalah calon guru dan guru matematika tingkat sekolah menengah pertama di Kabupaten Indramayu. Alat pengumpulan data yang digunakan dalam penelitian ini yakni (a) lembar observasi; (b) pedoman wawancara; (c) angket; (d) tes evaluasi adopsi teknologi. Sedangkan analisis data yang dilakukan yakni mengumpulkan data, melakukan pengkodean, menganalisis kode, menyajikan data, menyimpulkan dan memverifikasi kesimpulan. Pengolahan data secara kualitatif tersebut dibantu dengan menggunakan software AtlasTi. Hasil penelitian menyimpulkan bahwa (1) Pada tahap investigasi sebagian besar guru menggunakan beberapa aplikasi diantaranya yaitu, Zoom Meeting, YouTube, WhatsApp, PowerPoint, Google Meet, Google Form, Google Drive, Google Classroom, Geogebra dan Blog sekolah. (2) pada tahap strategi, peneliti mengadakan diskusi dan workshop dengan beberapa guru matematika dengan dasar hasil penelitian pada tahap investigasi tentang penggunaan ICT pada pembelajaran matematika serta kesulitan yang dirasakan oleh guru selama pandemi COVID-19. (3) pada tahap implementasi, guru menggunakan aplikasi yang telah dibuat atau yang sudah jadi sebelumnya. Pada tahap ini, langkah awalnya adalah mempersiapkan siswa mengguanakan aplikasi tersebut dengan cara mengarahkan dan membimbing siswa untuk mengubduh (download) aplikasi tersebut serta menjelaskan cara menggunakan media pembelajaran matematika yang berupa aplikasi yang bisa diakses melalui smartphone tersebut. (4) Pada tahap evaluasi, diperoleh kesimpulan bahwa integrasi media pembelajaran matematika berbasis ICT cukup efektif dalam meningkatkan hasil belajar matematika siswa.

Abstract

This study is motivated by the persistently low level of students’ mathematical problem-solving ability in the topic of sequences and series, despite its importance in the senior high school mathematics curriculum. The purpose of this study is to identify and describe factors that inhibit students’ problem-solving ability in sequences and series at SMA Negeri 2 Indramayu from the perspectives of mathematics teachers. This research employed a descriptive qualitative approach involving several mathematics teachers at SMA Negeri 2 Indramayu. Data were collected through semi-structured interviews focusing on instructional methods, internal and external inhibiting factors, strategies implemented by teachers, and an overview of students’ problem-solving abilities. The findings indicate that teachers use a variety of instructional methods, including direct instruction, deep learning approaches, STAD-type cooperative learning, visual approaches, and GeoGebra; however, their implementation is constrained by time limitations and classroom conditions. Internal inhibiting factors include low learning motivation, students’ reluctance to engage, weak mastery of basic concepts, and difficulties in understanding word problems. External factors include limited learning facilities, less conducive classroom environments, and restricted instructional time. Teachers attempt to overcome these obstacles through interactive media, e-modules, educational games, personal approaches, scaffolding, and visualization, although these strategies have not yet been implemented optimally. These findings emphasize the need for more systematic, problem-solving-oriented lesson planning in teaching sequences and series.
