the Perry Model [4] and the Reflective Judgement Stages of King and Kitchener? [5]Theoretical FrameworkOur theoretical framework consists of the Perry model of intellectual development, first formedduring the 1960’s, and the King and Kitchener Reflective Judgement Model, beginning in1994.[4] [5] [6] Both models are forms of epistemic cognition, involving the role of uncertaintyand context in the acquisition of knowledge, and its effects on the development of beliefs aboutspecific types of knowledge. It appears that the higher levels require the use of critical thinking.Perry originally identified nine levels of cognitive skills leading to knowledge from a state of“right” vs. “wrong” to a state of awareness that knowledge is relativistic and

In addition to racial/ethnicminority groups historically underrepresented in STEM more broadly, students who are from rural areas,who are the first generation to attend college, who are not able bodied, and those who lack financialresources are often not adequately prepared in their K-12 education, and often do not meet the minimumstandardized test scores to be admitted into engineering programs, particularly at land grant universities. Many engineering colleges are creating institutional resources to support student success and toreduce the historical barriers

student math and science performance has beento use inquiry learning for promoting teachers’ deep understanding of foundational STEM(science, technology, engineering, and math) concepts and the processes and the connectionsbetween them. Research shows that STEM teachers in U. S. schools lack content knowledge andmastery of subject-related pedagogy that enables them to teach content most effectively1. Theyalso lack a sense of the connections among concepts that reveal mathematics as an internallylogical and coherent system of knowledge2. This forces teachers to use lectures to deliver Page 13.241.3content, which emphasizes procedure over engagement

This project was extremely effective in creatingsixteen NCJETS (North Carolina Junior Engineering and Technology Society) high school clubs in sevencounties of the Central Piedmont region of North Carolina.

S. population is like me (and Ican’t quote an exact source for this number either – I got it from learning psychologist FredKeller7 in a conversation with him). I don’t receive vocal information as efficiently as I do whenI read about something – I can always read text over again, but it isn’t usually possible to“replay” a lecture or a conversation. So my learning skills don’t match the lower levels of Dale’sCone. But after 43 years of teaching engineering subjects I am quite comfortable with the ideasthat, for most engineering students, Visual Receiving is superior

Each innovation places new demands on theexisting system into which they are introduced. The engineering manager is often asked to provide the needed leadership in these innovation-basedprojects because of this individual's technical expertise and training. Technical expertise in (1) the specificinnovation and (2) project management in general is not enough. The successful selection, planning, andimplementation of innovation within an organization requires that someone in the organization sell the change.The classic marketing process of identifying the target market(s) and selecting the
