humanperceptions, understandings, and realities are based on the lived experiences of individuals(Cardellini, 2006; Crotty, 1998; Gordon, 2009; Kincheloe, 2005). Individuals create, interpret,and recognize knowledge in diverse and contextual ways (Windschitl, 2002). An individual isseen as an active knower and as a consequence personal reflections on experiences are integral tothe data collection process (Crotty, 1998; Fosnot, 2005; Schwandt, 2001).

The instrument also measured students’ability in conducting self-directed learning and reflection, which are very important elements indeveloping and enhancing problem solving skills. The instrument shows the degree of students’problem solving process skills, whether they usually take the surface or deep approach.

done using student reflections recorded after completing MEAs. Students insections of the courses that used MEAs rated their knowledge and understanding of theseprofessional skills significantly higher than students in sections that did not use the MEAs. As aresult we suggest that engineering faculty seriously consider using MEAs as a tool to improveboth student learning and the attainment of a number of ABET outcomes in addition to providinga process for assessing that attainment. By combining pre- and post-concept inventories with theMEA implementation, faculty can better document learning gains, and thus have acomprehensive tool for ABET assessment. This should prove especially helpful in those areaswhere previous assessments may have shown

lessons in ethics were lacking in the classroom.Involvement Influenced Students’ Abilities to Articulate Ethical Development The students who attended the engaged institutions often articulated their ethicaldevelopment by demonstrating how they process various scenarios. As students reflected onethical decision-making, common elements emerged: acknowledging an ethical dilemma,processing how to respond, and finally, identifying where they are in the decision makingprocess. One senior at Charlie University offered a reflection on the ethical decision-makingprocess: I feel like I‟m often surprised at our school. Like I think they teach us to be very ethical engineers but I‟m often surprised by how unethical some people‟s behavior

implement reflects themany ways engineer take designs from ideas to reality. Many engineers do build designs using abroad array of techniques. Perhaps one of the biggest differences between engineeringdisciplines is the specialized methods and technologies they use to implement designs. Howeversome engineers implement ideas through manipulation of information, such as designingcomputer software or producing plans. Here the real value is the information in the blueprint orcode, not the medium (paper or magnetic disk) that contains the information. Another option forimplementing a design is to contract another company to build it. In this case the engineer workswith the company to ensure the work is done properly.The fourth step of the engineering

While micro-level events arealmost always real-time and non-reflective, “the macro level of identity typically requires theperson to explicitly reflect on what the person considers stable and
