Gunter, Helen; Ribbins, Peter – Educational Management & Administration, 2002
The second of two linked articles develops two more mapping typologies: first, an approach to the what, why, and how of leaders, leading, and leadership; and second, the presentation of possible positions that knowledge workers can take when they use and produce knowledge about leadership practice. (Contains 10 notes and 73 references.) (MLF)

Stephenson, Philip; Warwick, Paul – Investigating, 2001
Provides a progression of terms of underlying concepts related to moving and falling objects, and links these concepts to activities that are appropriate for various age ranges. Speculates on the role of teacher knowledge in effective science teaching. (DDR)

Raggad, Bel Gacem – Information Processing & Management, 1996
A consultation quality control model (CQCM) developed for an expert system (ES) integrated both ES performance measures and end-user judgment values. Simple decision theory concepts were used to design the CQCM. Results show end users belong to different categories characterized by utility functions and the weights they assign to ES consultation…

Chen, Zhengxin – Information Processing & Management, 1996
Discusses similarities and differences between knowledge acquisition in expert systems and requirement acquisition in others kinds of information systems (particularly decision support systems). Examines role-limiting methods for automated knowledge acquisition and their integration from the problem-solving perspective. Suggests a feasibility…

Pillay, Hitendra – Australian Journal of Adult and Community Education, 1995
A model illustrates how humans interact with information and construct representations using short- and long-term memory. It shows that learners' prior knowledge and effective instructional materials have a significant effect on how competence is translated into good performance. (SK)
Descriptors: Competence, Job Performance, Knowledge Representation, Long Term Memory

Sadler, Philip M. – Journal of Research in Science Teaching, 1998
Reports on a study that uses psychometric modeling to rank the appeal of a variety of children's astronomical ideas on a single uniform scale. Findings support the view that alternative conceptions may be markers of progress toward understanding. Contains 82 references. (DDR)
Descriptors: Astronomy, Concept Formation, Data Analysis, Educational Strategies

Tsai, Chin-Chung – International Journal of Science Education, 2000
Argues for using "conflict maps" as a way of enhancing science teaching and learning. The conflict map emphasizes not only the use of discrepant events, but also the resolution of conflict between students' alternative conceptions and the scientific conception. Discusses the conflict map as an instructional aid for teachers or as a…

Seroglou, Fanny; Koumaras, Panagiotis; Tselfes, Vassilis – Science and Education, 1998
Addresses two research questions pertaining to the search for students' potential alternate conceptions within the history of science and the possibility of helping students overcome these misconceptions through historical experiments. Contains 19 references. (DDR)
Descriptors: Educational History, Electricity, Higher Education, Knowledge Representation

Reed, W. Michael; Ayersman, David J.; Kraus, Lee A. – Journal of Educational Multimedia and Hypermedia, 1997
Investigates the effects of context-weak versus context-strong tasks and learning style on the citation-frequencies and citation-percentages of four mental models (semantic networks, concept maps, frames/scripts, and schemata) students perceived to be inherent in a hypermedia learning environment. (Author/AEF)

Losee, Robert M. – Information Processing & Management, 2001
Increasing information retrieval performance using phrases and part-of-speech (POS) information is one example of a type of decision-making performance that is improved when using this linguistic information. The relative effectiveness of using multi-term phrases as opposed to individual terms is shown, as well as the relative worth of POS tagged…

Schroeder, Eileen E.; Grabowski, Barbara L. – Journal of Educational Computing Research, 1995
Describes a study of undergraduates that compared navigational study strategies, the extent of lesson coverage, and attitudes about learning with three types of hypermedia lessons to examine how learners use different types of graphical browsers in a learner-controlled hypertext system to construct personalized representations of the content…

Shipstone, David; Cheng, Peter C-H. – School Science Review, 2001
Shows how box diagrams and AVOW diagrams may be used to solve problems concerning networks of resistors that obey Ohm's Law. Presents outcomes and feedback from students and teachers. Concludes with suggestions as to how these techniques might be incorporated into the teaching of basic circuit theory. (Contains 22 references.) (DDR)

Ferry, Brian; Hedberg, John; Harper, Barry – Journal of Interactive Learning Research, 1998
Reports on preservice teachers' use of a concept-mapping tool to create/modify concept maps about science-related elementary curriculum-content knowledge. Data from interviews, journals, and analysis of the concept maps showed how the preservice teachers used the tool to construct their curriculum-content knowledge in the form of more powerful…

Ding, Wei; Soergel, Dagobert; Marchionini, Gary – Proceedings of the ASIS Annual Meeting, 1999
Investigates the information representation power of different modalities in the video data in order to collect empirical evidence for video surrogate creation and thus better support effective video browsing and information retrieval. Three types of video surrogates were created and compared under two user tasks--verbal comprehension and visual…
