Based on our empirical studies of effective human tutoring, we developed an Intelligent Tutoring System, iList, that helps students learn linked lists, a challenging topic in Computer Science education. The iList system can provide several forms of feedback to students. Feedback is automatically generated thanks to a Procedural Knowledge Model…

In this paper, we describe multimodal learning analytics (MMLA) techniques to analyze data collected around an interactive learning environment. In a previous study (Schneider & Blikstein, submitted), we designed and evaluated a Tangible User Interface (TUI) where dyads of students were asked to learn about the human hearing system by…

Discusses the possibility and usefulness of applying Habermas' universal pragmatics to analyze information retrieval interaction. Examines current studies of human computer interaction (HCI) and presents a case study that investigated the initiation and development of verification of validity claims in HCI from the universal pragmatics…

Interactive systems must be designed to furnish error information to the user and must be able to accept a modification to the input and continue to cycle until convergence on the desired output is reached. (10 references) (Author)

Reports a preliminary investigation into the man-machine interaction aspects of online searching, including the methodology developed for observing and recording man-machine interface in the use of online information retrieval systems. Three references are cited, and a bibliography lists 16 sources. (FM)

The contradictory nature of the phrase user-oriented interface (UOI) as commonly applied to retrieval systems is discussed, and a different approach to the problem made feasible through improvements in the technology is described. (Author/JPF)

As an exploration of the frustration experienced by users of an on-line interactive retrieval system, students participated in an experiment using an experimental reference retrieval system for library literature. It was anticipated that significant variations in user behavior would be displayed by the control and experimental groups. (19…

Discusses the concept of information scent in a Web site, which is based on mental associations between concepts. Describes research in the field of human-computer interaction, including how humans locate information and semantic networks; and discusses navigation success, user testing, good links, and facet-based browsing. (LRW)

Provides a synopsis of a session that addressed the interaction between users of information retrieval systems and intermediaries, including presentations on (1) the role of face-work; (2) user-intermediary-computer interaction; (3) issues of democracy in interpersonal interaction; and (4) a conversation-analytic approach to the pre-online search…

On the 14th and 15th of January, 1971, a workshop on The User Interface for Interactive Search of Bibliographic Data Bases was held in Palo Alto. The participants were provided in advance with a challenge paper and with a number of papers prepared in response to that challenge. The Workshop sessions themselves were devoted exclusively to focussed…

Presents an overview of the IR-NLI II system, an expert interface that allows users to access online information retrieval systems and that encompasses user modeling capabilities. Highlights include the design of the system, the structure and content of stereotypes that represent typical classes of users, and construction of user models.…

Presents results of a study that explores factors of user-Web interaction in finding factual information, develops a conceptual framework for studying user-Web interaction, and applies a process-tracing method for conducting holistic user-Web studies. Describes measurement techniques and proposes a model consisting of the user, interface, and the…

A consideration of the development of on-line systems in terms of the computer changes that made on-line searching possible, and the use of these changes by information retrieval systems. (Author/KP)

Hypermedia and object oriented programming systems (OOPs) represent examples of "open" computer environments that allow the user access to parts of the code or operating system. Both systems share fundamental intellectual concepts (objects, messages, methods, classes, and inheritance), so that an understanding of hypermedia can help in…

Discusses the CODER system, which was developed to investigate the application of artificial intelligence methods to increase the effectiveness of information retrieval systems, particularly those involving heterogeneous documents. Highlights include the use of PROLOG programing, blackboard-based designs, knowledge engineering, lexicological…
