Helping students better understand scientific publications is one of the essential tasks of higher education. This paper presents a novel learning/reading environment that incorporates innovative scaffolding methods that aim to enable students to readily access open educational resources (OER) and read and comprehend the paper in a collaborative reading environment within a course. The new system, OER-based Collaborative PDF Reader (OCPR), captures and characterizes students' emerging information needs when they read a paper, while also autorecommending high quality OERs, e.g., presentation videos, slides, or Wikipedia pages, when students ask for clarifying content (OER-based Scaffolding). The study was conducted in a course for students to read an article, ask questions, and rate resources suggested by the OCPR system. The preliminary results show that the students tend to ask elementary questions and rate video resources higher than other resources. The results will inform future improvement of the OCPR system.

With the rapid development of information technology, E-Business system has gradually become an effective means for enterprises to raise their management efficiency, save office resources, and achieve reasonable resource allocation. The traditional contract management mechanism for most enterprises is completed by manual processing, thus, the official business efficiency is very low and the waste of resource is serious. Therefore, this paper presents Design of Project Contract Management System Based on J2EE Architecture to solve the existing contract management problems. The system design follows the principles of advanced, economical, reliable, high efficient, open, easy to operate and easy to maintenance. According to the characteristics of projects, the system design is based on B/S structure, J2EE platform, MVC model design scheme. Based on the UML system analysis methods, we carry out a detail analysis on the contract management's relative business and practical functions that need to be realized. On the basis of the feasibility study and requirement analysis, this paper discusses the system function design and the database design in detail. By the way, we carry out the system functions by using the J2EE integration architecture based on Web Work + Spring + Hibernate. The contract management system provides a scientific and highly efficient contract management platform for the majority of enterprises. [ABSTRACT FROM PUBLISHER]
