We address the problem of predicting the correctness of the student's response on the next exam question based on their previous interactions in the course of their learning and evaluation process. We model the student performance as a dynamic problem and compare the two major classes of dynamic neural architectures for its solution, namely the…

Educational systems use models of student skill to inform decision-making processes. Defining such models manually is challenging due to the large number of relevant factors. We propose learning multidimensional representations (embeddings) from student activity data -- these are fixed-length real vectors with three desirable characteristics:…

Knowledge components (KCs) define the underlying skill model of intelligent educational software, and they are critical to understanding and improving the efficacy of learning technology. In this research, we show how learning curve analysis is used to fit a KC model--one that was created after use of the learning technology--which can then be…

The increasing use of educational technologies in classrooms is producing vast amounts of process data that capture rich information about learning as it unfolds. The field of educational data mining has made great progress in using log data to build models that improve instruction and advance the science of learning. Thus far, however, the…

For an intelligent tutoring system (ITS) to earn its "I", it must be able to (1) accurately diagnose students' knowledge structures, skills, and/or learning styles using principles, rather than pre-programmed responses, to decide what to do next; and (2) adapt instruction accordingly. While some maintain that remediation actually…

Examines an emerging shared metaphor, the business pattern, in the context of the encapsulation of wisdom. Discusses the logical evolution into "business patterns" and offers a more fully-realized template to illustrate the intent and to provide a framework for future development. Provides a prototypical example of a documented business pattern…

The Partnership for Research in Spatial Modeling (PRISM) project at Arizona State University (ASU) developed modeling and analytic tools to respond to the limitations of two-dimensional (2D) data representations perceived by affiliated discipline scientists, and to take advantage of the enhanced capabilities of three-dimensional (3D) data that…

Suggests that the development of good chemistry teaching and the pursuit of research have essentially the same structure. Similarities include the need for a clear focus, efficiency in time and effort, and a direction that is more often right than wrong. (DDR)

Argues that discussing theories, including their origin, development and replacement by other theories, can help students understand both the objective and subjective aspects of the scientific process. (DDR)

Argues that Albert Einstein preceded Karl Popper in formulating the fundamental premises of hypothetism. Presents the original text and ideas from an article published by Einstein in 1919. (DDR)

This research study focused on the knowledge structure of the domain of physics by describing the knowledge of experts, intermediates, and novices. In order to investigate these representations, a reiterative categorization task was employed using novice, intermediate, and expert subjects (N=27). The categories were classified as theory-, model-,…

This paper reports on an interdisciplinary theoretical framework for the characterization of models and modeling that can be useful in application to chemistry education. The underlying argument marks a departure from an emphasis on concepts that are the outcomes of chemical inquiry about how knowledge growth occurs through modeling in chemistry.…

Provides historical information on the incorporation of physics as a subject into secondary schools in Spain. Cites religious and political tensions as early roadblocks to curriculum development. (DDR)

Describes the first moon-radar echo experiment conducted by Zoltan Bay in Hungary and comments on Bay as a model for contemporary physics education. (DDR)

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)
