Despite providing advanced coursework online to learners around the world, massive open online courses (MOOCs) have had notoriously low completion rates. Self-regulated learning (SRL) frames strategies that students can use to enhance motivation and promote their engagement, persistence, and performance selfmonitoring. Understanding which SRL subprocesses are most relevant to the MOOC learning context can guide course designers and instructors on how to incorporate key SRL aspects into the design and delivery of MOOCs. Through surveying 643 MOOC students using the Online Self-Regulated Learning Questionnaire (OSLQ), the present study sought to understand the differences in the use of SRL between those who completed their course and those who did not. MOOC completers were found to have significantly higher applications of one SRL specific subprocess, namely goal setting. Additional SRL subprocesses of task interest/values, causal attribution, time management, self-efficacy, and goalorientation also emerged from an analysis of open-ended responses as key contributors to course completion. The findings from this study provide further support regarding the role of SRL in MOOC student performance and offer insight into learners' perceptions on the importance of SRL subprocesses in reaching course completion.
Di bidang pendidikan kedokteran, pola belajar yang diterapkan pada saat ini berpotensi menimbulkan stres pada mahasiswa. Fakultas Kedokteran di Indonesia menganut cara pembelajaran berbasis masalah (problem-based learning) yang terpusat pada mahasiswa (student-centered learning). Proses pembelajaran yang terpusat pada mahasiswa dalam kegiatan belajar dan mengajar tersebut, bila tidak dikelola dengan tepat akan mengakibatkan stres berlebih yang pada akhirnya memengaruhi kemampuan belajar dan prestasi akademik mahasiswa. Karena itu, penelitian ini bertujuan untuk mempelajari apakah terdapat perubahan yang berarti pada pola belajar dan hubungannya terhadap stres serta prestasi akademik pada mahasiswa kedokteran. Dilakukan penelitian cross-sectional terhadap 193 mahasiswa/i fakultas kedokteran Universitas Prima Indonesia. Adapun parameter yang diukur dalam penelitian ini meliputi: pola belajar, tingkat stres, prestasi akademik dan hubungan antara perubahan pola belajar, stres dan prestasi akademik. Penelitian ini menggunakan metode analisis uji korelasi Pearson dan mendapati hasil bahwa 184 dari 193 orang mahasiswa/i fakultas kedokteran Universitas Prima Indonesia memiliki tingkat stres normal, 167 mahasiswa/i merasakan terdapat perubahan pola belajar selama berkuliah daring dan ditemukan hubungan yang signifikan antara tingkat stres dan pola belajar strategi deep serta stres dan prestasi akademik. Dapat disimpulkan bahwa terdapat hubungan antara perubahan pola belajar strategi deep dengan stres dan stres dengan prestasi akademik mahasiswa/i Universitas Prima Indonesia.
Background: The excessive use of chemotherapy drugs such as doxorubicin might induce cardiovascular diseases. Heart-specific biomarker enzymes such as LDH and BNP indicated the early signs of cardiotoxicity. However, there is no report on the effect of bay leaf on LDH and BNP nor its bioactive compounds and histopathology analysis.Objective: This study aims to determine the cardioprotective effect of Ethanol Extract of Bay Leaf (EEBL) based on phytochemical analysis, LDH and BNP levels, and cardiac histology of rats administered with doxorubicin.Methods: About 24 Wistar rats were divided into six groups treated with 100 mg/kg BW, 300 mg/kg BW, and 500 mg/kg BW of EEBL with CMC-Na 0.5 %, vitamin E, and doxorubicin. Preconditioning was 14 days, followed by 21 days of intraperitoneal administration. LDH and BNP parameters were measured on days 1st, 7th, 14th, and 20th. Histology analysis was conducted on day 21st.Results: Dark green EEBL showed sufficient physical quality and properties for practical application in pharmacy. EEBL has significantly affected LDH, BNP, and cardio recovery dose-dependent. The most effective doses were observed at 500 mg/kg BW, and its performance is not statistically different from those of the commercial vitamin E. The histopathological images revealed significant improvements in interstitial edema, wavy fibers, hemorrhage, intracellular vacuole, and inflammatory cell infiltration. Here we report six bioactive compounds obtained from EEBL have cardioprotective effects; Neophytadiene, squalane, phytol, methyl palmitate, stigmasterol, and 9,12-Octadecanoic acid methyl ester.Conclusion: This study has shown the promising potential of bay leaf extract as a cardioprotector with sufficient quality pharmacological standards.
