Learners can collaborate with each other to achieve a lesson objective. In the collaboration, they can provide each other with guidance in order to identify mistakes and improve their achievements. With the rise of online instructions, this small-scale exploratory study aimed to see how proficient learners guided their less proficient classmates in correcting the grammatical accuracy of sentenc...

among structured peer-to-peer systems, chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. however, chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing latency an...

abstract— peer-to-peer ( p2p ) systems have been the center of attention in recent years due to their advantage . since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . this paper investigates the use of genetic ...

Assembly of certain classes of bacterial and animal viruses requires the transient presence of molecules known as scaffolding proteins, which are essential for the assembly of the precursor procapsid. To assemble a procapsid of the proper size, each viral coat subunit must adopt the correct quasiequivalent conformation from several possible choices, depending upon the T number of the capsid. In...

This study presents an EFL (English as a Foreign Language) instructional model in which peer interaction improves motivation, confidence, satisfaction, and actual performance of students. Researchers used peer interaction for repeated assignments via Computer-Mediated Communication (CMC) to study how focused peer interaction contributes to changes in the four factors. EFL students in Taiwan int...

This study examined and organised comments made by teachers participating in a variety of learning communities in order to sort a list of recommendations for future development of webbased teachers’ training taking into consideration possible trajectories of web powerful technological innovations. The comments are organised under a theoretical framework of professional scaffolding.

It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding...

Two studies documented and evaluated parental scaffolding of 3and 4-year-olds' spatial communication. In Study 1, children gave directions to parents about locations of objects. Three-year-olds gave ambiguous directions more often than 4-year-olds, and parents used directive prompts more often with 3-year-olds than 4-year-olds, Study 2 compared the effectiveness of parental prompts in a control...

Many pedagogues have argued that learners should shape their own learning experience whilst tutors should facilitate this process of knowledge construction. Digital environments have been often used in an attempt to scaffold learning in these innovative learning settings. However the results obtained have been mixed both in terms of learning achievements and learners' satisfaction. We argue tha...
