Abstract

In the current Covid-19 transition period, an effective vocational learning model innovation is needed. The number of vocational learning models during this pandemic needs further study for a successful implementation. This study empirically verifies the vocational learning model during the Covid-19 pandemic and analyzes the factors that hinder vocational learning in the Covid-19 era. Systematic literature review and Meta-Analysis (PRISMA) were used as methods for conducting this research. The reviewed articles were 30 most recent articles from 2019 to 2020. All articles were classified based on author, year published, type of journal or conference, method, vocational learning model, and findings. The study reveals that the search results prove an increase in the number of articles published from 2019-2020. The results showed that e-learning is the most widely used learning model in vocational education. E-learning developed for vocational education must be able to measure competency outcomes through an e-portfolio, virtual-based, and easy to use. The obstacles that can be identified are the difficulty of teachers and students to adapt to changes in vocational learning from conventional to online learning during the COVID-19 transition; lack of working skills for vocational education students that are unobtainable during online learning; infrastructure problems; and uneven distribution of networks, especially in remote areas that have difficulty accessing the internet. Di masa transisi Covid-19 saat ini, dibutuhkan inovasi model pembelajaran vokasi yang efektif digunakan. Banyaknya model pembelajaran vokasi di masa pandemi ini perlu dikaji lebih lanjut yang tepat untuk diimplementasikan. Penelitian ini bertujuan untuk memverifikasi secara empiris model pembelajaran vokasi di masa pandemi covid 19 serta menganalisis faktor yang menghambat pembelajaran vokasi di era Covid-19. Systematic literarature review dan Meta-Analisis (PRISMA) digunakan sebagai metode untuk melakukan penelitian ini. Artikel yang ditinjau sebanyak 30 artikel terbaru dari tahun 2019 hingga 2020. Semua artikel diklasifikasikan berdasarkan penulis, tahun terbit, jenis jurnal atau konferensi, metode, model pembelajaran vokasi, dan temuan. Hasil studi disampaikan sebagai berikut. (1) Hasil penelusuran membuktikan adanya peningkatan jumlah artikel yang diterbitkan dari tahun 2019-2020. (2) Hasil penelitian menunjukan bahwa model pembelajaran e-learning merupakan pembelajaran yang paling banyak digunakan pada pendidikan vokasi. (3) E-learning yang dikembangkan untuk pendidikan vokasi harus bisa mengukur hasil kompetensi melalui e-portofolio, berbasis virtual dan mudah digunakan. (4) Hambatan yang dapat diidentifikasi adalah: (a) kesulitan adaptasi pengajar dan siswa dalam perubahan pembelajaran vokasi pada masa transisi covid-19 dari konvensional ke online, (b) kurangnya keterampilan bekerja para siswa pendidikan vokasi yang tidak didapatkan selama pembelajaran online, (c) masalah infrastruktur dan pemerataan jaringan yang belum merata terutama di daerah terpencil yang kesulitan akses internet.

Abstract

Abstract - This research is motivated by the poor air quality in the room at home that can cause Sick Building Syndrome (SBS). The purpose of this research is to increase public awareness of the environment through indoor air quality workshops, with a Pre-Experimental method and One Group Pre-Test Post-Test research design. The sample in this study was Pasteur RW6, Sukajadi District at Bandung City, which was selected based on criteria including non slum areas, as well as high community participation. The results showed that the level of public awareness, knowledge, attitudes, and actions on air quality in the room before the Workshop was in the medium category. Then it increased after the Workshop, which was on a relatively moderate increase in knowledge. This can be seen from the majority of people who already know the importance of indoor air quality, but the knowledge of specific components that affect indoor air quality is still not understood. Whereas attitudes and actions experienced a relatively small increase due to the knowledge gained in the Workshop not being implemented in the form of real attitudes and actions in daily life because people's habits are difficult to change. Keywords – Environmental Awareness, Indoor Air Quality, Workshop, Community Awareness

Abstract

The Open Educational Resource (OER) is a source of digital learning materials that can be accessed, used, and distributed by everyone and is copyright licensed. This study aims to conduct a systematic library review in investigating the impact of Open Educational Resource (OER) implementation on student learning outcomes, the impact of OER on costs for students and learning challenges using OER. The method used in this study is Systematic Literature Review (SLR). This paper presents a publication review paper (2015-2020) or the last 5 years on OER. The article search process uses search techniques using the keywords OER (Open Educational Resource), Open Educational, and MOOCs (Massive Open Online Course) on those from reputable article databases. The selected article is then sorted by the inclusion criteria process and the findings are synthesized to answer the problem formulation. The findings suggest that the effectiveness of OER learning and conventional textbooks has no significant differences, both of which have the same learning outcomes. In terms of costs, OER has an impact on saving students’ money. The challenge of learning in the future is the need for intensive support for teachers so that there is no longer a gap in teacher understanding related to OER. The role of librarians is required to collaborate in developing, modifying, and distributing OER, as well as in advocating to support the appropriate use of OER between teachers, students, and institutions. Research has implications as a strong foundation in designing and implementation strategies related to OER in education.
