In this paper, we investigate the problem of monitoring human activities using a network of sensors, including video cameras, in a smart home environment. We introduce an unsupervised method for mining a new kind of qualitative temporally structured activity models from sensor data. We present an application of our method to the recognition of activities of daily living in an elderly care context.

this paper is about concept maps and how they can assist in the learning ofconcepts of mathematics. first the paper presents the theoretical backgroundand working denitions for concept maps. then this study examines the impactof using concept maps in learning of fractions. results of this study indicatedthat using this strategy was eective in learning of fractions for fourth-gradestudents. th...

language learning strategies have been controversial ever since rubin’s (1975) landmark article more that 30 years ago. to this day, there is no consensus regarding exactly what a strategy is, which has impeded research initiatives and at times threatened the validity of research findings. the relationship between strategies and successful language learning has also been questioned. based on th...

  Using small groups in teaching and learning has a long history. Evidence suggests that by applying some defined guidelines, it would be possible to reinforce the effectiveness of the small groups teaching. One of these guidelines is related to ice-breaker activities which would be applied by the facilitators at the start of the session, which are noticeably significant. The aim of the presen...

in spite of the highly beneficial applications of corpus linguistics in language pedagogy, it has not found its way into mainstream efl. the major reasons seem to be the teachers’ lack of training and the unavailability of resources, especially computers in language classes. phrasal verbs have been shown to be a problematic area of learning english as a foreign language due to their semantic op...

Learning objects have been proposed as an approach to creating and sharing learning resources. There are further advantages to be gained if the objects can be reused. This paper emphasizes the creation of learning environments from reusable learning objects. It suggests that reuse can be simplified by a learning object classification, which can be used to semantically construct learning activit...

This study develops and implements a computer-assisted learning (CAL) program with both multiplicative facts practices and the instruction of meaning behind these facts. The effectiveness of CAL on the development of multiplication abilities is also explored. Eight CAL activities are developed to teach multiplication to second grade elementary school students. The CAL program is comprised of th...
