Abstract

Abstrak: Matematika adalah salah pelajaran yang wajib dipelajari oleh siswa dari sekolah dasar hingga sekolah tinggi. Pembelajaran dilakukan dengan tatap muka antara guru dan siswa. Namun, kini berubah sejak adanya COVID-19 pada bulan Maret 2020. Proses pembelajaran dilaksanakan jarak jauh dengan menggunakan berbagai media yang mendukung pembelajaran online, salah satunya adalah Edmodo. Melalui Edmodo, guru diharapkan dapat membuat bahan ajar yang menarik untuk siswa, salah satunya dengan membuat Lembar Kerja Siswa (LKS). LKS dapat menjadi panduan untuk latihan pengembangan aspek kognitif maupun panduan untuk pengembangan semua aspek pembelajaran. Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran berupa Lembar Kerja Siswa (LKS) yang valid, praktis, dan efektif melalui pembelajaran berbasis kontekstual sebagai bahan ajar daring menggunakan media Edmodo di SMA Harapan Medan. Penelitian ini dilakukan melalui dua tahap, yakni pengembangan LKS berbasis kontekstual dengan mengacu pada model 4-D yaitu pendefinisian (define), perencanaan (design), pengembangan (develop), dan penyebaran (disseminate). Temuan hasil penelitian diperoleh LKS telah memenuhi kriteria valid dan kepraktisan LKS disimpulkan berdasarkan pendapat ahli yang menyatakan LKS dapat digunakan dengan sedikit revisi dan respon siswa yang positif terhadap LKS. Keefektifan LKS berdasarkan ketuntasan belajar siswa secara klasikal pada uji coba I sebesar 85,3% dan uji coba II sebesar 90% Kata-kata kunci: Lembar Kerja Siswa ; Kontekstual ; Edmodo

Abstract

The purpose of this study was to see the effectiveness of the Discovery Learning learning model based on local wisdom, the differences in communication skills and self-efficacy of students who were taught using the local wisdom-based Discovery Learning learning model with those taught using conventional learning. This study also aims to find out how to increase students' communication skills and self-efficacy when taught using the Discovery Learning method based on local and conventional wisdom. This research method is quasi-experimental with Posttest Only Control Group Design with descriptive analysis used to achieve this goal. This research was conducted at UPMI Medan. The population of this study were all students of UPMI, while the sample was students of the Department of Management. This study found that the Discovery Learning learning model based on local wisdom was effectively used with a percentage of learning implementation worth 94.12% and student responses 89.50%. then there are differences in communication skills and self-efficacy between experimental and control class students, as evidenced by the sig. (2-tailed) 0.000005 between the control and experimental groups. This study also found a greater increase in communication skills and self-efficacy of students who were taught using Discovery Learning based on local wisdom than conventional learning, as seen from the average scores of 76.12 (experimental group) and 58.00 (control group), indicating an increase of 12 0.04%.

Abstract

Pendidikan karakter merupakan aspek penting dalam proses pendidikan untuk membentuk kepribadian dan moral mahasiswa. Kepercayaan diri adalah salah satu hasil yang diharapkan dari pendidikan karakter yang efektif. Penelitian ini bertujuan untuk mengeksplorasi pengaruh pendidikan karakter terhadap kepercayaan diri mahasiswa di Universitas. Metode penelitian yang digunakan adalah studi survei dengan menggunakan kuesioner yang disebarkan kepada sampel mahasiswa dari berbagai program studi di Universitas. Kuesioner ini dirancang untuk mengukur tingkat pendidikan karakter yang diterima oleh mahasiswa dan tingkat kepercayaan diri yang mereka miliki. Hasil penelitian menunjukkan bahwa terdapat hubungan positif antara pendidikan karakter dan kepercayaan diri mahasiswa. Mahasiswa yang mendapatkan pendidikan karakter yang lebih baik cenderung memiliki tingkat kepercayaan diri yang lebih tinggi. Beberapa aspek pendidikan karakter, seperti integritas, empati, ketekunan, dan tanggung jawab, secara khusus berkontribusi pada peningkatan kepercayaan diri. Penemuan ini memiliki implikasi penting bagi lembaga pendidikan dalam mengembangkan program pendidikan karakter yang efektif untuk meningkatkan kepercayaan diri mahasiswa. Peningkatan kepercayaan diri dapat membawa dampak positif pada prestasi akademik, hubungan sosial, dan kesiapan mahasiswa untuk menghadapi tantangan di dunia nyata.

Abstract

This study aims to analyse the successful implementation of project-based learning model in mathematics learning at university level. Literature studies and field observations were conducted to evaluate the implementation of project-based learning models in several higher education institutions. The results showed that the implementation of project-based learning model in mathematics learning in higher education has positive impacts, among others: 1) increasing students‘ active involvement and motivation in the learning process, 2) developing mathematical competence, critical thinking skills, and other 21st century skills, 3) encouraging meaningful and contextualised learning, and 4) improving students’ collaboration and communication skills. However, there are some challenges in its implementation, such as: lecturer readiness, resource availability, and curriculum adjustment. The implication of the results of this study is the need for innovative mathematics curriculum development, increased lecturer competence, and adequate institutional support to optimise the implementation of project-based learning in higher education. This study provides valuable insights for mathematics education practitioners in designing and implementing student-centred learning oriented towards the development of 21st century competencies.
