The field of adaptive e-learning is continuously developing. More research is being conducted in this area as adaptive e-learning aims to provide learners with adaptive learning paths and content, according to their individual characteristics and needs, which makes e-learning more efficient and effective. The learner model, which is a representation of different learner’s characteristics, plays a key role in this adaptation. This paper presents a systematic literature review about learner modelling during the last 5 years, describing the different modelled characteristics and the adopted modelling techniques and modeling types: automatic modeling and collaborative modeling. 107 publications were selected and analyzed, and six categories of the modelled characteristics were identified. This literature review contributes to the identification of the learners’ individual traits and presents the most used modelling techniques for each of them. It also identifies the latest research trends of Learner Modeling and generates future research directions in this field.

Event based estimation with correlated noises     

Shaikshavali Chitraganti  Samir Abkerane 《Journal of The Franklin Institute》2019,356(13):7533-7547

For a linear system having event based measurements and correlated noises, a state estimation algorithm is proposed. A general event based sampling is employed to obtain the measurements, where in the case of unavailability of measurements, event based strategy itself is used to obtain approximate state and covariance estimates. To deal with correlated noises, a two-step ahead prediction approach is employed to obtain recursive equations for estimated state and covariance. The obtained results are illustrated using a simulation example.  相似文献

Private supplementary tutoring among primary students in Bangladesh   总被引：1，自引：0，他引：1  

Samir Ranjan Nath 《Educational studies》2008,34(1):55-72

Using the databases created under Education Watch, a civil society initiative to monitor primary and basic education in Bangladesh, this paper explores trends, socioeconomic differentials and cost in private supplementary tutoring among primary students and its impact on learning achievement. The rate of primary school students getting access to private supplementary tutoring is increasing at two percentage points per year and reached 31% in 2005. Incidence of private tutoring was greater among boys and urban students than respective counterparts. Educated parents and well‐off families were more likely to arrange supplementary tutoring for their children. A wide variation in the cost for private tutoring prevailed. The tutees spent 46% of their total private expenditure for education on supplementary tutoring. Supplementary tutoring helped students learn more than those who had no such support. Private tutors for primary school students have become a well‐accepted norm. Finally, a number of social implications are discussed.  相似文献   

DNA chip

This article presents a brief overview of DNA chips, or microarrays. Microarrays are a very significant technological development in molecular biology, and are perhaps the most efficient tool available for functional genomics today.  相似文献
