Abstract

To response the needs for 21st century competencies among chemistry students, a novel approach on learning in higher education is paramount. This study presents the development and evaluation of a flipped classroom learning system for chemical kinetics, designed to enhance digital literacy and guided inquiry through Discord. This research followed the Educational Design Research (EDR) model outlined by Plomp and Nieveen and limited to development studies; yielding  a refined learning system prototype. The developed learning system was validated by five lecturers from Universitas Negeri Padang, resulted in content (0.85), and construct validity (0.82). Meanwhile, the practicality of the learning system was also evaluated by students and lecturers, resulted in practicality indexes of 88% and 85%, respectively. All of the results suggest high level of validity and practicality meaning the learning system has achieved the quality criteria content, structure, and usage wise. These results imply for the utilization platforms like Discord for higher education learning to promote student-centered learning and digital literacy.

Abstract

Telah dilakukan penelitian tentang sintesis nanopartikel CoFe2O4 menggunakan daun sirih merah sebagai bahan pelindung. dengan perbandingan mol 3:2 Co(No3)2 : Fe(No3)3. dan dikarakterisasi menggunakan geussmeter, FTIR dan XRD. Kekuatan magnet yang dihasilkan paling tinggi pada penambahan daun sirih merah sebanyak 5 ml dan perbandingan komposisi Co(No3)2 : Fe(No3)3 sebesar 3:2 dengan nilai 0,14nt, pada uji FTIR terdapat fungsional golongan senyawa fenolik yang berasal dari daun sirih merah, hal ini menunjukkan bahwa sintesis nonpartikel Cobalt Ferrite dapat dilakukan dengan menambahkan daun sirih merah sebagai bahan pelindung.

Abstract

This study aims to determine the effectiveness of Discord instructional media integrated with flipped guided inquiry learning on reaction rates on students’ learning outcomes. The instructional media has been tested for its validity and practicality prior to the study. The study was conducted using quasi-experimental with pretest-posttest non-equivalent control group design. Sample consists of 72 students from SMA Negeri 13 Padang participated in this study, with class F1 and F2 as the experiment and control group respectively. Students’ learning outcomes were assessed with instrument consisting of multiple choices questions. Results shown the higher N-gain value from experimental group with 0.70 compared to control group with 0.33. Furthermore, the t-test results yielded a value of t-count = 8.11 > t-table = 1.99, indicating that the means were statistically significant. These findings suggest Discord instructional media integrated with flipped guided inquiry learning was effective to improve students’ learning outcomes.
