Abstract

Probability theory is one of the subjects that are difficult to understand by students semester 2 Prodi mathematics education. This can be seen from the low activity resulting in low yield learning probability theory students. This research aims to find out whether the method learning card games can increase the activity of students and student learning outcomes. Research conducted on students semester 2 Prodi mathematics education FKIP UNBARI lesson 2017/2018 year is a research action research which is a combined approach of quantitative and qualitative approaches. Research done in cycles. Each cycle consists of four steps, namely planning, implementation, observation and reflection. The data was collected by using the observation sheet for student activity data and test results for learning. Research findings show that learning mathematics with the method of card games can increase the activity and results of student learning math semester 2 Prodi mathematics education. Based on the results of the study it can be concluded that learning with the method of card games can increase the activity of the students and the results of learning probability theory students semester 2 Prodi mathematics education FKIP UNBARI.

Abstract

This research is backgrounded by the low ability to think creatively by students on the subject of discussion of compound opportunities. This is due to the less interesting learning process, the teacher only gives assignments and videos from the internet, while students only do the assignments without any discussion so learning mathematics very boring for students. To help students, a learning is needed that can optimize the ability to think mathematically creatively. One of the learnings that improve students' creative thinking skills is the discovery learning. The purpose of this study is to determine the influence of project-based discovery learning on the creative thinking ability of class XII of SMAN 8 Jambi City.This research is a quasi-experimental with Nonequivalent Pretest-Postest Control Group Design. The population used was all students of class XII IPA consisting of 236 students, the sample consisted of 65 students of the experimental class, namely XII IPA1 with the project-based Discovery Learning model and the control class, namely XII IPA2 with model being taught. The sample was selected by random sampling. The instrument used in this study was a test of creative thinking skills.Analysis using parametric statistical test Independent sample test test with SPSS for Windows Version 25.From the results of analysis is Asymp Sig. (2-tailed) is 0.000, it can be seen that Asymp Sig. (2-tailed) < 0.05 so that H0  rejected and H1 accepted. The final results, the project-based Discovery Learning learning model has a significant effect on students' creative thinking ability.
PERBANDINGAN MODEL QUANTUM TEACHING DAN MODEL PEMBELAJARAN LANGSUNG TERHADAP KEMAMPUAN PEMAHAMAN KONSEP MATEMATIS SISWA KELAS X IPA SMA ADHYAKSA 1 JAMBI Dona Alvionita Putri; Eni Defitriani; Relawati Relawati

Abstract

Penelitian ini dilatarbelakangi oleh adanya permasalahan dalam pembelajaran matematika di kelas X SMA Adhyaksa 1 Jambi yaitu rendahnya kemampuan pemahaman konsep siswa. Penelitian ini bertujuan untuk mengetahui tingkat kemampuan pemahaman konsep siswa terhadap materi pembelajaran dengan menerapkan dua model pembelajaran yaitu, Model Quantum Teaching dan Model Pembelajaran Langsung, serta melihat mana yang lebih baik antara keduanya. Penelitian ini menggunakan metode quasi eksperimen, populasi dalam penelitian ini adalah siswa kelas X IPA SMA Adhyaksa Jambi tahun ajaran 2022/2023, sampel diambil dengan menggunakan teknik random sampling, sehingga diperoleh dua kelas sampel yang diberi perlakuan yang berbeda. Kelas sampel tersebuat adalah kelas X IPA 1 sebagai kelas eksperimen dan kelas X IPA 2 sebagai kelas kontrol. Setelah dua kelas sampel diberikan perlakuan yang berbeda, pada akhir penelitian diberikan tes akhir (post-test). Hasil penelitian diperoleh nilai rata-rata kemampuan pemahaman konsep matematis kelas eksperimen adalah 77,43 dengan simpangan baku 10,14 dan nilai rata-rata kemampuan pemahaman konsep matematis siswa kelas kontrol 71,67 dengan simpangan baku 10,54, serta hasil dari uji hipotesis diperoleh  dan  pada taraf nyata 0,05. Dari hasil perhitungan tersebut terlihat bahwa  dengan demikian  diterima, artinya kemampuan pemahaman konsep matematis siswa melalui Model Quantum Teaching lebih baik daripada kemampuan pemahaman konsep matematis melalui Model Pembelajaran Langsung.

Abstract

Kurangnya alat bantu ajar bagi pendidik untuk mengajar peserta didik agar dapat memahami konsep pada materi ajar menjadi latar belakang masalah, karena itu, dibutuhkan adanya pengembangan LKPD matematika berbasis PBL merupakan saran untuk membantu dan mempermudah pendidik dalam menyampaikan konsep dari materi yang ingin disampaikan. Dengan jenis penelitian pengembangan (R&D) dari model pengembangan ADDIE yang memiliki 5 tahapan pengembangan, subyek penelitian adalah peserta didik kelas XI MIPA 1 untuk uji lapangan dan kelas XI MIPA 3 untuk uji perorangan dan uji kelompok kecil. Dimana instrument penelitian pada pengembangan ini berupa lembar penilaian LKPD untuk para ahli guna memperoleh data kevalidan LKPD, dan lembar respon peserta didik pada uji coba produk untuk memperoleh data kepratisan LKPD. Hasil penelitian LKPD matematika berbasis PBL ini adalah sebagai berikut: 1) hasil validasi ahli materi sebesar 96,36%, 2) hasil validasi ahli media sebesar 83,64%, 3) hasil validasi ahli desain sebesar 90%, 4) respon peserta didik pada uji coba perorangan sebesar 77,34%, 5)respon peserta didik pada uji coba kelompok kecil sebesar 93,09%, dan 6) respon peserta didik pada uji coba lapangan sebesar 92,18%. Berdasarkan analisis data yang telah diperoleh dari penilaian LKPD oleh para ahli (materi, media, desain) dan data respon peserta didik yang diperoleh dari uji coba produk, maka dapat disimpulkan bahwa LKPD yang dikembangkan memenuhi kriteria valid dan praktis.

Abstract

Numeracy literacy skills are the most important part of the abilities that every student must have. The limited number of numeracy literacy instruments at SMP Negeri 2 Jambi is one of the factors causing less than optimal mathematics learning. Students are still lacking in understanding questions, formulating, identifying and interpreting mathematical problems properly and correctly. To train these abilities, an ethnomathematics-based numeracy literacy test instrument is needed. This research aims to describe the process of developing an ethnomathematics-based numeracy literacy test instrument and determine the validity index of the ethnomathematics-based numeracy literacy test instrument. This research is development research that adapts the Plomp model which consists of initial assessment stage, design stage, realization/construction stage, and test, evaluation and revision stage. Data collection techniques in this research are field note techniques, questionnaire techniques, validation techniques and test techniques with research instruments in the form of field note sheets, questionnaire sheets, validation sheets and test questions. Data analysis uses Aiken's formula and empirical validity uses product moment correlation. The results of this research show that at the design stage, there was a difference of opinion between the two validators regarding the grid, there was one indicator question that was not in accordance with basic competencies. These differences are then analyzed and revised according to input and suggestions from the validator. The researcher improved the question grid as well as the test questions, resulting in good question items, and the results of content validation by 4 expert validators calculated using the Aiken's formula obtained a validity value of 0.785. These results indicate that the ethnomathematics-based numeracy literacy test instrument is declared valid from three aspects, namely; materials, constructs and language.
