Students can practice skills and acquire knowledge by doing coursework. However, in conventional coursework activities, each student is assigned the same exercises, without considering learners’ diversity. Moreover, students typically have difficulty in receiving assistance for completing their exercises after class. Therefore, some students cannot learn effectively when doing their coursework....
The avian inner perivitelline layer (IPVL), a homologous structure to the mammalian zona pellucida, is deposited between the granulosa cells and the oocyte cell membrane during folliculogenesis. The glycoprotein meshwork of the IPVL forms a 3-dimensional matrix and possesses important functions in the fertilization process: it contributes to the binding of avian spermatozoa to the oocyte and in...

The term zone of proximal development is probably one of the most widely recognized and wellknown ideas associated with Vygotsky’s scientific legacy. This famous concept is more precise and elaborated than its common reception or interpretation (Chaiklin, 2003, p. 39). It could be viewed in a narrow context, i.e. within the concrete problem of relations between learning and development. But to ...
Intelligent tutoring systems offer a way for schools to meet the challenges of providing effective instruction to students with a diverse range of abilities, interests and needs [Self, 1999]. AnimalWatch is a computer-based tutor that uses artificial intelligence techniques to provide individualized math instruction for 9-12 year olds. Math word problems are integrated into narratives about end...
Vygotskij’s educational concept of the Zone of Proximal Development (ZPD) calls for an adaptation of learning activities to the present state of learner’s knowledge and abilities. At the same time, Vygotskij’s educational model includes a strong bent towards social and collaborative learning. In practice, a tight integration between personalized and collaborative learning is called for. Along t...
By Nada Dabbagh Scaffolding is originally a Vygotskyan (Lev Vygotsky, 1896-1934) concept based on the idea of providing supportive assistance to the learner within the parameters of a learner’s zone of proximal development (Zo-ped or ZPD) (Wood, Bruner, & Ross, 1976). ZPD is a measure of a learner’s current ability and knowledge what he/she is able to perform with no assistance and the learner’...
The tropospheric model is the key in space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI). In this paper, we established site-wise empirical Wuhan University Tropospheric Model (WTM) by using 10-year (2011–2020) monthly mean 5-year (2016–2020) hourly ERA5 reanalysis data, where Zenith Path Delay (ZPD), mapping function, horizo...
