This paper presents current results in developing a practical approach, methodology and tool, for the development of knowledge bases and agents by subject matter experts, with limited assistance from knowledge engineers. This approach is based on mixed-initiative reasoning that integrates the complementary knowledge and reasoning styles of a subject matter expert and a learning agent, and on a ...

vs. Contextualized Representations During our initial team discussions, the engineering subject matter expert (SME) brought to our attention the fact that engineering textbooks at the college level typically represent engineering content in abstract form, that is, with generic symbols (Moore, Miller, Lesh, Stohlmann, & Kim, 2013; Nathan et al., 2013).

Introduction Despite pressures for quick one-size-fits-all fixes to providing teachers with professional development, the California History-Social Science Project (CHSSP) has maintained a focus on providing long-term, subject-specific professional development. The CHSSP has sought opportunities to partner with districts, schools, and teachers so as to help build teachers' content knowledge, ac...

This article raises the question of what K-12 teachers need to know to teach mathematics and science well. It begins by examining reform proposals for K-12 science and mathematics teaching with an eye toward defining what good teaching practice consists of. It then examines a wide range of literature to delineate the varieties of knowledge that have been associated with this kind of teaching. W...

ABSTRACT Despite the increase in and diversity of disclosure channels available, our understanding how managers incorporate channel features into their decisions remains incomplete. I provide evidence that choose relatively rich offer multiple cues, opportunities for interaction, linguistic (i.e., earnings call, as compared to press release) communicate complex information. The positive relatio...
