ABSTRACT Pedagogical content knowledge, the content-specific knowledge which embodies the aspects of content most germane to its teachability and which is most likely to distinguish the understanding of the content specialist from the pedagogue. has been widely regarded as important for effective teaching of complex subject matter such as science. This paper focuses on one aspect of pedagogical...

Eight criteria have been established in the AgRISTARS Program to guide the evaluation and comparative analysis of crop yield models. The establishment of these criteria closely corresponds to the spirit of Dr. Hartley's ASA Presidential Address, particularly section three entitled "The Cooperation Between Statistician and Subject Matter Specialist" (1980). In our case the cooperation is between...

background and purpose: the fact that who is more qualified to teach the emp (english for medical purposes) courses has long been the cause of argument between the heads of language departments (lds) on one side and those of discipline-specific departments(dsds) on the other side. this research was conducted to study the views of both sides as well as those of students in some emp english class...

Background. This study aimed to determine whether it is possible to predict driving safety of individuals with homonymous hemianopia or quadrantanopia based upon a clinical review of neuroimages that are routinely available in clinical practice. Methods. Two experienced neuroophthalmologists viewed a summary report of the CT/MRI scans of 16 participants with homonymous hemianopic or quadrantano...

This study describes and interprets (a) a student teacher's decisions about task content and content progression across an elementary and high school sport unit and (b) those aspects of his pedagogical content knowledge that he used to explain and justify his decisions. The student teacher's pedagogical content knowledge of dividing and sequencing subject matter can be summarized briefly: first...

The Next Generation Air Transportation System (NextGen) envisions a flexible, dynamic airspace structure that is better able to adapt to changing traffic conditions than today’s rigid system of airways and airspace sectors. However, to develop effective NextGen airspace concepts, a thorough understanding is needed of current airspace configuration practices, and of the constraints that influenc...

In decision making a key source of uncertainty is people’s perception of information which is influenced by their attitudes toward risk. Both, perception of information and risk attitude, affect the interpretation of information and hence the choice of suitable courses of action in a variety of contexts ranging from project planning to military operations. Visualization associated with the dyna...

This paper presents an experiment of parallel knowledge base development by subject matter experts, performed as part of the DARPA’s Rapid Knowledge Formation Program. It introduces the Disciple-RKF development environment used in this experiment and proposes design guidelines for systems that support authoring of problem solving knowledge by subject matter experts. Finally, it compares Discipl...

This paper examines the personalization of online training simulations which are a key modern approach in computer aided education. More specifically it focuses on the difficulties involved in authoring personalized training simulations. The composition of such systems is very difficult which has hampered their wide spread adoption [Joolingen, 03]. Presently adaptive training simulations can on...
