Abstract

This study is part of a development of problem solving learning model with aspects of ontology, epistemology, and axiology (Model PS-TRILOGI) to improve critical thinking skills and student understanding of Thermochemistry concepts. These objectives can be achieved if the model PS-TRILOGI is valid, practical, and effective. The study design followed the Research and Development. The effectiveness of the model PS-TRILOGI assessed by observers and implemented through the instrument test critical thinking skills and understanding of Thermochemistry concepts at 33 students in Chemistry Education Studies of Tadulako University. The results obtained showed that the percentage of positive responses given by students is very high due sense of excitement, novelty, interest, and support learning media are respectively 94.95%; 90.91%; 90.91% and 96.97%. Indicators that measure critical thinking skills is the interpretation, analysis, inference, and self-regulation. N-gain value for the indicator interpretation, analysis, and self-regulation in middle category of 0.5; while indicators inference at the high category of 0.7. Understanding of the Thermochemistry concept 13 students has a value n-gain of 0.8 to a high category. Based on the results obtained show that the model PS-TRILOGI is effective.

Abstract

Permasalahan mitra (guru-guru yang tergabung dalam MGMP kimia kota Palu) adalah: a) Kemampuan guru dalam memahami makna, manfaat, dan cara penggunaan media pembelajaran masih rendah, b) Kemampuan dalam pengetahuan media pembelajar ataupun pembuatan LKPD (Lembar Kerja Peserta Didik), untuk keperluan pengganti praktikum di laboratorium sekolah menjadikan rendahnya produktivitas guru dalam mengembangkan materi ajar ke dalam media pembelajaran dan LKPD, c) Pihak sekolah belum menyediakan media atau software komputer yang mendukung dalam pembuatan media pembelajaran dan LKPD praktikum secara online ataupun dengan memanfaatkan materi yang ada di sekitar peserta didik, d) Kurangnya narasumber yang bisa ditempati bertanya jika guru mengalami kesulitan untuk membuat media pembelajaran ataupun membuat LKPD untuk keperluan pengganti praktikum di laboratorium sekolah. Untuk itulah kami menganggap perlu dilakukan suatu kegiatan yang mampu meningkatkan pemahaman dan keterampilan para guru dalam mengembangkan profesionalisme, khususnya dalam pengembangan media pembelajaran ataupun membuat LKPD untuk keperluan pengganti praktikum di laboratorium sekolah. Kegiatan yang akan dilaksanakan meliputi ceramah tentang pentingnya penguasaan konsep dan praktikum dalam pembelajaran kimia, memberikan contoh LKPD untuk kegitan eksperimen/praktikum berbasis lingkungan selanjutnya kerja praktek dimana para peserta dibimbing/didampingi oleh tim pengabdi, mulai dari memberikan informasi kepada guru-guru yang diperkirakan sangat menunjang untuk penguasaan konsep selanjutnya, mendesain LKPD dengan metode eksperimen/praktikum berbasis lingkungan, serta menyesuaikan dengan kompetensi dasar yang hendak dicapai. Setiap kegiatan di damping oleh tim pengabdi dan pada kegiatan akhir, masing-masing guru menyerahkan hasil pekerjaannya. Kegiatan pengabdian ini menghasilkan LKPD berbasis lingkungan yang aman dan mudah dilakukan oleh siswa.

Abstract

Di masa Pandemi Covid-19 telah terjadi perubahan mendasar dalam pelaksanaan pembelajaran kimia Perkuliahan tatap muka dan praktek di laboratorium untuk mengakomodasi keterhubungan tiga level representasi tidak lagi dapat dilaksanakan. Pembelajaran kimia digantikan secara penuh melalui pembelajaran online. MGMP Kimia di Kota Palu menyadari pentingnya melakukan berbagai upaya agar proses pembelajaran kimia berjalan baik dari segi penyampaian materi pembelajaran maupun pelaksanaan praktikum di laboratorium. Salah satu aplikasi yang bisa digunakan dengan mengkombinasikan berbagai media pembelajaran yang selama ini digunakan oleh guru-guru kimia (antara lain: aplikasi zoom, whatsapp, Google Class Room, LMS, dll) adalah mengunakan Ice Cream Screen Recorder. Peserta pelatihan sebanyak 40 orang yang merupakan guru-guru mata pelajaran kimia yang tergabung dalam kelompok MGMP Kimia SMA Kota Palu. Kegiatan pengabdian pada mitra Musyawarah Guru Mata Pelajaran (MGMP) Kimia kota Palu dalam Bahan Ajar Digital Menggunakan ice cream recorder dalam pembelajaran online, telah terlaksana dengan baik berkat kerjasama yang baik dengan berbagai pihak. Hal tersebut tergambar dengan adanya luaran berupa bahan ajar digital menggunakan ice cream recorder yang telah peserta buat dari hasil pelatihan dan pendampingan pengabdian ini.
