Team-based learning (TBL) stresses applying knowledge rather than absorbing knowledge in class; studies have investigated the use of TBL and its merits in different teaching courses (e.g., medical science and business). TBL is most effective when students learn autonomously before class. However, the ability of autonomous learning is highly…

From the perspective of Vygotsky's Sociocultural Theory and Zone of Proximal Development (ZPD), dynamic assessment (DA) highlights the role of mediation in the learning process by unveiling the distance between actual learning proficiency and potential learning development. DA is more helpful in fostering students' ability to solve problems…

In online educational systems we can easily collect and analyze extensive data about student learning. Current practice, however, focuses only on some aspects of these data, particularly on correctness of students answers. When a student answers incorrectly, the submitted wrong answer can give us valuable information. We provide an overview of…

I examine the formation of power as it relates to canonicity through online delivery systems, Amazon and Goodreads, and the academic sector in the contemporary period. The digital age has radically changed literature by providing for a textuality of literature that is multi-channeled, and this project responds by engaging new critical lenses for…

Practical abilities are important for students from majors including Computer Science and Engineering, and Electrical Engineering. Along with the popularity of ACM International Collegiate Programming Contest (ACM/ICPC) and other programming contests, online judge (OJ) websites achieve rapid development, thus providing a new kind of programming…

A recommender system is a piece of software that helps users to identify the most interesting and relevant learning items from a large number of items. Recommender systems may be based on collaborative filtering (by user ratings), content-based filtering (by keywords), and hybrid filtering (by both collaborative and content-based filtering).…

This evaluation of the DIALOG Medical Connection, a new user-friendly system that provides access to several online health sciences databases, describes searching, changing databases, documentation, online help, access, costs, and training, and compares the features of this system with those of other systems that are currently available. Three…

Enumerates principal management objectives of database management systems (data independence, quality, security, multiuser access, central control) and criteria for comparison (response time, size, flexibility, other features). Conventional database management systems, relational databases, and database machines used for backend processing are…

The last installment in a three part series compares commands and features for accessing and manipulating the results obtained from the DIALOG and QUESTEL information systems. Highlights include enhancements to syntax and defaults, options for output arrangement and retrieval, reformatting of selected data, memory, unique features, and examples.…

Second article in a three-part series focuses on enhancements of search commands and features in the DIALOG and QUESTEL information systems. Highlights include system responses and capacities (aids to searching); search commands and features (proximity searching, field specification, limits); concatenating complex requests; and saving search…

First of a three-part series provides an overview of pre-enhancement DIALOG and QUESTEL information systems including their histories, databases, query languages, and services. Description of implementation of DIALOG Version 2 and QUESTEL PLUS and a general comparison of system features provide a preview of specific comparisons in part 2. (EJS)

A comparative evaluation of two computerized reference retrieval systems, INSTRUCT (a statistically-based system) and PLEXUS (a knowledge-based system) examined their retrieval effectiveness for a set of 19 queries and 512 documents on gardening. Best results were obtained by using terms suggested by PLEXUS as the basis for an INSTRUCT search. (36…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Discusses major features and capabilities of gateway software--microcomputer software packages that act as interfaces between users and bibliographic retrieval systems they are searching--i.e., communication, interface, auxiliary programs. Four programs (In-Search, Universal Online Searcher, Search Helper, microDisclosure) are reviewed and…

Discusses the variety of search command languages among online systems and provides suggestions for creating online information retrieval manuals using a database management system such as dBASE III PLUS. An online systems comparison chart is included for INFOGLOBE, INFOMART, DIALOG, QUICK LAW, and REUTERS TEXTLINE. (LRW)
