This study mined student interactions with visual representations as a means to automate assessment of learning in a complex, inquiry-based learning environment. Log trace data of 143 middle school students' interactions with an interactive map in Research Quest (an inquiry-based, online learning environment) were analyzed. Students used the…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

This report provides a brief general summary of progress in a 2-year project renewing earlier work on the development of Individualized Instruction for Data Access (IIDA)--a system for teaching online searching techniques for bibliographic data bases--as well as an in-depth report on the IIDA computer system design. The Connector for Networked…

This report describes the development of a design and a small working model for a system for teaching and assisting in the performance of bibliographic on-line searches through the use of an intermediary computer. The system in its present form is intended for direct users of scientific and technical information systems. However, it is felt that…

Article focuses on the communication aspects of two types of information systems: computer assisted instruction (CAI), and computer based systems for information retrieval. (Author/RK)

Describes a microcomputer-based software package, Online Search Tutor (OST), which is designed to teach users online bibliographic searching. Modeled on software previously developed for the European Space Agency Information Retrieval Services (ESA-IRS), OST includes a database of 600 bibliographic records which will simulate actual search…

Describes a hypertext learning system in the United Kingdom that is designed to assist community pharmacists in recommending over-the-counter remedies to patients. The combination of hypertext's linking features with the knowledge-based components of expert systems is discussed, and the application of this model to other domains is explored. (five…

Discussion of educational technology and its impact on instructional methodology and the learning process focuses on six basic educational components necessary to trace technology variables directly to specific learning processes. Highlights include learning objectives; knowledge bases; instructional strategies; computer-based enhancements; and…

Man engages in the continuous construction of models to describe his reality. This assumption led to some instructional research at Oakland University, Rochester, Michigan, developing and testing a systems model for the classroom. A model building process labeled message storage and retrieval was developed in some detail. Using this retrieval…

Society and education are changing rapidly, and since computers are playing a significant role in these changes it is imperative that secondary school teachers become more fully informed about computers. Computers are of interest to learners because they have led to new theoretical developments, such as automata theory, have many practical…

Developed for the freshman writing program at University of Southern California (USC), Project Jefferson has two goals: to develop a model of computer-based instruction that includes the use of research tools and an interface that can be used with courseware in other disciplines; and to develop a researcher's notebook that permits easy access to…

To enhance both teaching and learning in an advanced undergraduate elective course on the interrelationships of plants and human affairs, the computer was used for information retrieval, multiple choice course review, and the running of three simulation models--plant related systems (e.g., the rise in world coffee prices after the 1975 freeze in…

As learners use World Wide Web-based distance learning systems over a period of years, large amounts of learning logs are generated. An instructor needs analysis tools to manage the logs and discover unusual patterns within them to improve instruction. However, logs of a Web server cannot serve as learners' portfolios to satisfy the requirements…

The paper examines in depth administrative and instructional uses of the computer in adult education. The author demonstrates: (1) positive findings related to the feasible use of the computer in data analyses and report writing for administrative purposes, and (2) preliminary, yet encouraging, findings in the area of computer managed instruction…

This study examined the cause-effect interconnectivity of various mental models utilized by 10 American and Australian teachers and media specialists when involved in one-on-one teaching-learning episodes using electronic resources in the context of researching information for authentic school assignments. The researchers investigated runability…
