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.

Abstract

This research was conducted at Singa Putih Prigen Featured MTs for the development of learning media for macromedia flash-based flat shapes. This study uses research and development (R&D) methods with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The purpose of this study was to determine the validity and response of students to learning media based on Macromedia Flash on curved page material. The sample of this research is Singa Putih`s superior MTs students. The research data collection technique used a validation questionnaire from material experts, media experts and student response questionnaires. The choice of this application was based on ease of use and the ability to combine visual, audio-visual and audio-visual resources. The research results were validated by media experts and material experts with a ratio of 86.32% and 82% respectively with the category "Very Valid". The results of the implementation of students using a questionnaire obtained a percentage of 82.8% in the very feasible category.

Abstract

Penelitian ini adalah penelitian kuantitatif yang bertujuan untuk mengetahui pengaruh model pembelajaran inkuiri terbimbing terhadap pemahaman konsep peserta didik. Metode penelitiaan yang digunakan dalam penelitian ini adalah metode penelitian eksperimen dengan desain Quasi Eksperimental. Bentuk quasi yang digunakan adalah pretest-posttest control group desing. Subjek dalam penelitian ini adalah peserta didik kelas VII-A dan VII-B di MTs. An-Nuriyah. Kelas VII-A menggunakan model pembelajaran inkuiri terbimbing (eksperimen) sedangkan kelas VII-B menggunakan model pembelajaran konvensional (kontrol). Hasil penelitian menunjukkan pemahaman konsep peserta didik pada kelas eksperimen (inkuiri terbimbing) lebih tinggi dari pada kelas kontrol (pembelajaran konvensional). Hal ini dapat dilihat dari rata-rata hasil tes pemahaman konsep peserta didik pada kelas eksperimen adalah 83,67 sedangkan rata-rata hasil tes pada kelas kontrol adalah 60,67. Begitu juga dengan hasil analisis data menggunakan uji-t dua sample independen yang menunjukkan nilai sig maka dapat disimpulkan ditolak yang artinya ada perbedaan pemahaman konsep peserta didik menggunakan model pembelajaran inkuiri terbimbing dengan model pembelajaran konvensional. Sehingga dapat disimpulkan bahwa model pembelajaran inkuiri terbimbing dapat berpengaruh terhadap pemahaman konsep peserta didik.

Abstract

Prestasi belajar dapat dipengaruhi oleh dua faktor, yaitu faktor internal dan faktor eksternal. Faktor internal diantaranya yaitu minat, bakat, dan kepercayaan diri, sedangkan faktor eksternal diantaranya yaitu faktor keluarga (cara orang tua mendidik), dan faktor sekolah (cara guru mengajar). Setiap peserta didik ingin mendapatkan prestasi belajar yang baik, tetapi untuk menghasilkan prestasi yang baik membutuhkan usaha. Penelitian ini termasuk jenis korelasi dengan pendekatan kuantitatif. Anggota populasi dalam penelitian ini adalah seluruh peserta didik kelas XI MIA di SMA Muhammadiyah 06 Paciran tahun 2020/2021 berjumlah 85 peserta didik yang terbagi menjadi 4 kelas dan peneliti mengambil dua kelas yang berjumlah 44 peserta didik sebagai sampel secara acak dengan cara diundi. Sebelum diundi peneliti melakukan uji homogenitas. Instrumen yang digunakan dalam penelitian ini adalah angket dan soal tes. Teknik analisis data dalam penelitian ini adalah analisis regresi linier sederhana dan regresi linier berganda. Berdasarkan hasil penelitian menggunakan uji simultan (uji F) menunjukkan bahwa pengaruh minat (X1), kepercayaan diri (X2), dan kreativitas (X3) berpengaruh signifikan terhadap prestasi belajar (Y) dengan nilai P - Value (sig) . Hasil penelitian menggunakan uji parsial (uji t) menunjukkan bahwa variabel minat berpengaruh signifikan terhadap prestasi belajar dengan nilai P - Value (sig) , kepercayaan diri berpengaruh signifikan terhadap prestasi belajar dengan nilai P - Value (sig) , kreativitas berpengaruh signifikan terhadap prestasi belajar dengan nilai P - Value (sig) . Koefisien determinasi menunjukkan bahwa persentase variabel X (minat, kepercayaan diri dan kreativitas) terhadap variabel Y (prestasi belajar) sebesar 88,7%. Artinya variabel prestasi belajar dapat dijelaskan atau dipengaruhi oleh variabel minat, kepercayaan diri dan kreativitas, sedangkan sisanya 11,3% dipengaruhi oleh variabel lain yang tidak teliti. Kata kunci : Minat, Kepercayaan Diri, Kreativitas, dan Prestasi Belajar

Abstract

Human resources (HR) are the only resources that have feelings, desires, skills, knowledge, encouragement, power, and work. All of these potential human resources affect the organization's efforts in achieving its goals. Advances in technology, development of information, availability of capital and adequate materials. Therefore, an HR information system is needed, in this study an information system was developed which has a function to archive data for lecturers, employees, identity archive data, education archive data, and training archive data. The purpose of developing this system is to make it easier for HR staff to manage HR archive data so that they can speed up data processing and produce information. The method used is the system development life cycle (SDLC), which has stages of planning, analysis, design, implementation of trials, and management. The programming language used is PHP and the database system uses MySQL. The results can display information about lecturer data, employee data, identity archive data, education archive data, training archive data, activity archive data and can be printed in the form of a recap in the form of a report.

Abstract

Learning at MI Nurul Huda Lengkong is still centered on educators which has an impact on student learning outcomes because students rarely solve problems independently. There needs to be an improvement in learning models to improve student learning outcomes. The learning model that can create an atmosphere of students who are free, creative, and independent in accordance with their abilities is the problem posing learning model. Problem posing is a learning model that requires students to compile questions or break down a problem into simpler questions and refer to solving the problem. The purpose of this model is to create a more interactive learning atmosphere and improve student learning outcomes. This research is quantitative correlational research. To find the influence between problem posing learning models on research learning outcomes using this type of experiment, by comparing the learning outcomes of problem posing and conventional learning. From the research that has been done, the average posttest score of the control class was 58.25 from 8 students and the experimental class was 81.625 from 8 students. This indicates that the problem posing learning model has an influence on improving the learning outcomes of grade 5 MI Nurul Huda Lengkong students.
