“…Untuk mencapai tingkat penggunaan yang tinggi sebuah LO sangatlah penting dibubuhi informasi yang berkaitan dengan topik konten di dalam metadata LO tersebut atau diistilahkan dengan anotasi metadata. Membuat anotasi sumber daya pendidikan dengan metadata terkait kompetensi membantu orang dan organisasi dalam mencari, mengambil, dan berbagi sumber belajar yang sesuai untuk program pengembangan kompetensi [2,3]. Anotasi untuk tujuan ini terkandung dalam metadata LO dalam bentuk beberapa tag yang menjelaskan tentang artefak pendidikan dari LO terkait seperti judul dokumen, penulis, abstrak, dll.…”

Penggunaan kembali bahan pembelajaran dalam sistem e-learning menjadi isu penting karena biaya pembuatan bahan e-learning itu mahal. Memperluas cakupan penggunaan bahan pembelajaran untuk bidang tertentu dapat dicapai dengan membubuhi keterangan (anotasi) di dalam metadata Bahan Pembelajaran (Learning Object, yang selanjutnya disingkat: LO) secara semantik sesuai dengan deskripsi bidang yang diminati oleh pengguna. Penelitian ini bermaksud untuk memperluas penggunaan kembali LO dari sebuah repositori e-learning berbahasa Inggris agar dapat digunakan sebagai materi tambahan pembelajaran mandiri melalui sistem e-learning dalam program pelatihan tenaga kerja. Kemiripan topik sebuah LO dihitung secara kuantitatif menggunakan pendekatan Kesamaan Tingkat Lexikal dengan memanfaatkan database WordNet sebagai basis kesamaan leksikal. Pendekatan ini dimaksudkan untuk mengkategorikan topik LO dengan topik deskripsi pekerjaan seorang peserta pelatihan dengan cara mengukur skor kesamaan antara makna tekstual dari judul, deskripsi, dan kata kunci LO dengan judul, deskripsi, dan kata kunci dalam deskripsi pekerjaan tertentu. Tujuan penelitian ini adalah untuk mengevaluasi tingkat akurasi pendekatan Kesamaan Tingkat Lexikal dalam menyimpulkan kesamaan topik dari LO. Berdasarkan percobaan, pendekatan ini memberikan tingkat akurasi yang rendah ketika menemukan dua topik yang serupa, namun mempunyai tingkat akurasi yang tinggi dalam menemukan dua topik yang berbeda.

“…Additionally, in [28], the authors provided a model to identify and classify competencies and learning outcomes in higher education, teaching technology and web information management. In [32], the authors developed a competency-based search system by using ontologies. They built competency ontology, content ontology and domain ontology to develop this search system.…”

Bridging Education and Labor Skills by a Novel Competency-Based Course Linked-Data Model

et al. 2019

Competency-based education (CBE) aligns with current requirements by providing students with competencies needed in real life. Emerging new styles of education, such as open courseware (OCW), massive open online course (MOOC) and open educational resources (OERs), play a role in renewing CBE by offering the required open materials. In this paper, we propose a novel competency-based course model(CBC model) that was developed with two aims. The first aim was to represent the fundamental concepts of CBE courses by exploiting the expressivity of ontologies. The second aim was to design a CBC model to act as a bridge between the existing ontologies that represent education and open materials and the ontologies that represent competencies from labor knowledge bases by exploiting linked-data interoperability. The model was designed to provide materials at the competency level in addition to the course level in order to allow students who fail one competency to repeat its materials rather than the whole course. Though the dynamic nature of labor knowledge bases, the integrated competencies from labors linked-data repositories will be automatically updated based on linked-data features. The use of W3C standards and linked-data ontology engineering principles to design the CBC model make it reusable and expandable. A proof of concept application was used to show the possibility of using the model in real life by applying the model to educational systems, such as LMS. Applying the model can increase a university's appearance on the web, thus enhancing its reputation. Additionally, the model can increase the links between education and labor that form a substantial contribution from the linked-data science perspective.

“…For example, Chang et al [9] have developed and implemented a learning contents providing service which is able to rank the search results for different users. The shortcoming of their work in our context is that it has not covered the sharing of other searching services, and it lacks feedback from potential users.…”

Sharing e-learning resources efficiently and effectively is a challenge. One barrier is that currently available resources have not been described accurately and do not readily interoperate. In this paper, we present an evaluation of our novel e-learning services approach which aims to overcome these problems. Results from the evaluation suggest that it is quicker and easier to discover and choose reusable e-learning materials via our service approach, and that the approach offers both practical and educational benefits for its users.
