The need of improving the education quality is insparable from the strategic role of teachers. One potential solution to develop the teachers quality is the use of information and communication technologies (ICTs). In this paper, we propose a Digital Learning - Lesson Study (DL-LS) that is an implementation of Lesson Study - a teacher learning method(More)
There is no doubt that the need of improving the quality of primary schools particularly in rural areas is very urgent for government. One of the most promising solution is through utilization of Information and Communication Technologies (ICTs). In this paper we present our effort and work in improving the quality of primary school teachers and the(More)
In this paper, we optimize low speed networks access for designing an efficient Voice over Internet Protocol network, especially in 64 kbps, 128 kbps, and 256 kbps bandwidth capacities. We draw some analytical approach based on Extended E-model to quantify some levels of quality of service. Using the model, those levels are determined by network parameters(More)
The previous research has developed Virtual Class Box design that uses multimedia conference technology to provide digital learning service [2]. However this technology is limited only to stream media files in realtime without the capability to save the content (recording capabilities). Our recent research improve this existing technology by providing(More)
Our previous research has successfully developed Virtual Class Box prototype that uses multimedia conference technology to provide digital learning service. This technology however faces a limitation in coverage and distance because the system needs a dedicated wireless infrastructure. Our recent research is to break this limitation by proposing augmented(More)
In Indonesia, the condition of education still tends to be unbalanced. The quality of education in urban areas is generally far better than the quality of education in rural areas. Education processes in rural areas face some problems like limited teaching resources, slight teaching tools, and monotonous teaching method. Therefore, an idea is emerged, a(More)
Wireless Local Area Network (WLAN) based on IEEE 802.11e provides Quality of Service (QoS) support at the Medium Access Control (MAC) sublayer. IEEE 802.11e MAC sublayer uses a function called Hybrid Coordination Function (HCF) with Enhanced Distributed Channel Access (EDCA). EDCA is a QoS mechanism that provides a priority scheme by differentiating(More)
In education, application of Information and Communication Technology (ICT) brings out the term of digital learning which can be used to support conventional learning process. Digital learning is one of alternative solutions to problems concerning good quality education disparities in rural areas, which is caused by the lacking of teacher resources. Case(More)
Development of multimedia from year to year increasing with the growing support of computer networks such as wireless LAN (WLAN) as a media intermediary. The one of method is streaming multimedia delivery over the internet from the server to the client to respond to client requests to a video and audio contained in a computer network. Factors that affect(More)
