Abstract

This research was conducted with the aim of overcoming the low learning motivation of students in mathematics through learning with the Problem Based Learning model with interactive multimedia. The subjects of this study were students of Class X Accounting at SMK Negeri 1 Wonorejo, which was located on Jl. PP Al-Yasini Kluwut, Wonorejo District, Pasuruan Regency with a total of 33 students. The research method used is quantitative descriptive analysis. The instruments used in this research were the students' learning motivation questionnaire and formative tests. The learning motivation questionnaire is used to find out whether students' learning motivation is still low after implementing problem based learning models with interactive multimedia. Meanwhile, formative tests are used to see the achievement of student learning objectives. The results showed that 30.3% of students belonged to the very high category and 69.7% of students belonged to the high category. Whereas for formative test results at the first meeting, it was found that 39.4% of students were classified as very good criteria, 45.5% of students were classified as good criteria, and 15.1% of students were classified as sufficient criteria. While the results of the second meeting test 48,5% of students got test results with very good criteria, 42,4% of students got test results with good criteria, and 9.1% of students still got test results with sufficient criteria. From the research results it can be concluded that problem based learning with interactive multimedia can overcome the low motivation to learn mathematics.

Abstract

Matematika merupakan salah satu bidang ilmu yang melatih untuk berpikir geometris. Untuk mengembangkan cara berpikir geometris perlu pemahaman konsep yang matang. Pentingnya belajar geometri sebagai sarana untuk mengembangkan konsep matematika lainnya. Peneliti menggunakan teori Anderson & Karthwohl tentang komponen pemahaman konsep. Penelitian ini merupakan penelitian ekploratif deskriptif yang bertujuan untuk mendeskripsikan secara utuh tentang pemahaman konsep peserta didik ASD dengan tingkat intelegensi rendah pada materi geometri di SLBN Cerme. Berdasarkan hasil penelitian, diperoleh deskripsi pemahaman konsep sebagai berikut: (1) menafsirkan, Subjek menginterprestasikan persegi seperti tahu dan persegi panjang seperti papan tulis; (2) memberi contoh, subjek memberikan contoh persegi dan persegi panjang dengan menggambar bangun yang tidak sesuai dengan sifat persegi dan persegi panjang; (3) menggolongkan, subjek menggolongkan bangun yang termasuk persegi, persegi panjang maupun bukan kedua-duanya; (4) meringkas, subjek menyebutkan secara sederhana tentang ciri-ciri persegi dan persegi panjang; (5)menyimpulkan, subjek menyimpulkan tentang pengertian persegi dan persegi panjang berdasarkan pengamatan; (6) membandingkan, subjek mengungkapkan tentang persamaan dan perbedaan persegi dan persegi panjang; (7) menjelaskan, diharapkan pada indikator ini subjek dapat mengkonstruk hubungan sebab akibat antar konsep geometri (persegi dan persegi panjang). Katakunci: Pemahaman Konsep, ASD dan Geometri

Abstract

This study aims to overcome the low ability to understand students' mathematical concepts in statistical material, especially the size of group data placements through learning with problem-based learning models using the gallery walk method. The research design used is a quantitative descriptive research design. This includes the stages of data collection, processing data, and interpreting the results. This research involved the subject, namely, students of class XII MIPA 1 at SMA Negeri 1 Tanjungsiang. The instruments used included diagnostic tests, formative tests, summative tests, teaching module implementation observation sheets, and teacher observation sheets. The results showed that the average score of the formative test at the first and second meetings was 71.5 in the medium category and 82.5 in the high category respectively. In addition, as a whole, the student achievement on indicators of understanding the concept as much as 78% is in the medium category. As well as the achievement of the learning objectives of students in the material size of the location of the group data of 78.28, it is in the category that has reached completeness, no need for remedial.

Abstract

Student motivation is one of the factors that influence learning outcomes. Therefore the authors pay special attention to this by conducting research on student motivation. Especially in this modern era, students tend to feel bored more quickly following conventional learning which is still centered on the teacher. So that learning must be made as interesting as possible, in order to trigger students' interest in participating in learning. Therefore, the authors decided to carry out learning using the Problem Based Learning (PBL) model assisted by website-based application media in the form of wordwall.net learning games and wizer.me e-LKPD media to increase student learning motivation. The reason for using the two website-based applications is the suitability of the content contained in the application, so that it can be adapted to the characteristics of existing students, such as several types of games that students can choose from on the wordwall.net website, and during the learning process students tend to want to do something instant. , such as listening to material rather than writing material, inputting answers using a cellphone, and so on. These habits or desires can be overcome using the wizer.me application because there are several supporting features, such as video link input, image/photo input, voice recording input, writing answers directly using your finger on your cellphone (hand writing), and many more. This is also the background of the article entitled "The Effect of the Problem Based Learning (PBL) Learning Model assisted by the application based on the wordwall.net website and e-LKPD wizer.me on student learning motivation".

Abstract

This study aims to improve students' mathematics learning outcomes through the application of Problem Based Learning (PBL) assisted by Video Animation. This research includes classroom action research referring to the Kemmis and Taggart models with 2 cycles consisting of planning, action, observation and reflection stages. The research subjects were 32 students of class XI DPIB A at SMK Negeri 2 Trenggalek. The instruments used were observation sheets on the implementation of the Learning Implementation Plan (RPP) and learning outcomes tests in the form of essay questions. The results showed that, 1) the implementation of lesson plans had increased, namely in cycle I at the first meeting of 55 and at the second meeting of 60, then in cycle II, the score increased to 62 at the first meeting and 64 at the second meeting, 2) the average score of students' test results increased, namely in the first cycle of 63,78 and in the second cycle of 80,00. Classical completeness has increased, namely in the first cycle of 62,50% increasing to 84.37% in the second cycle. Thus, it can be concluded that the application of the Problem Based Learning assisted by Video Animation can improve students' mathematics learning outcomes. Keywords: Problem Based Learning, Video Animation, Learning Outcomes.
