esophageal carcinoma is a relatively blind process since there is nomethod to monitor the tumor oxygen level during the treatment. In this paper, we presentan optical technique to monitor molecular oxygen level in the PDT milieu. The methoddescribed herein is a reflection oximetry technique designed with small semiconductorlasers and a silicon photodiode. The light used for monitoring system comes from twosemiconductor diode lasers of 650 nm and 940 nm wavelengths. The two lasers and thephotodiode are integrated into a small package which is then mounted onto a ballooncatheter containing the PDT light delivery system. The lasers and photodiode arepowered and controlled by a control box that is connected via a cable. The light sourcesand the

reflected onto a position-sensitive detector (PSD). When the cantilever bends due toadsorption-induced surface stress, the reflected light moves on the photo-detector surface, and thismovement is proportional to the cantilever deflection. The Stoney formula, which relates thebending of cantilevers to the surface stress given by Eq. (1), is now widely used in surface stressmeasurements and in the design of cantilever sensors, Et 2 R= , (1) 6Δσ (1 − ν )where E is elasticity of the cantilever, t is the thickness of cantilever, ν is the Poisson ratio, andΔσ is

. With this came the recognition that no one standard coursemodel could be developed for a single course on technological literacy. Rather, four standardcourse models were established and slated for development as part of the follow-on NSF/NAETechnological Literacy for Undergraduates Workshop, which was held in March 2007 [1,2].The four standard course models are: (1) Technology Survey Course, (2) Technology FocusCourse, (3) Technology Design Course, and (4) Technology Critique, Assess, Reflect, orConnect Course. The framework described here was created to serve as a guideline fordeveloping these standard course models but also as a means to evaluating existing technologicalliteracy courses.Description of the Proposed FrameworkThe framework was

firms are onboard with sustainable design, it hasin fact become a selling point for consultant services. LEED is at this point in engineering history thefirst system to allow for engineers to have standards for sustainable design. The ethical conflict willdiminish with time as standards are developed, amended and revised to reflect the need for sustainabledesign [1]. IV. CONCLUSIONWhy do engineers focus with such zeal on "engineering ethics?" Ethics are ethics. Have we, by creat-ing a set of ethics for our professional lives as engineers, made the concept of ethical behaviour socomplex and confusing that we fail to act in ways consistent with moral principles when faced with anethical dilemma?

for different topics. According to Glickman "Effectiveteaching is not a set of generic practices, but instead is a set of context-driven decisions aboutteaching. Effective teachers do not use the same set of practices for every lesson . . . Instead,what effective teachers do is constantly reflect about their work, observe whether students arelearning or not, and, then adjust their practice accordingly (Glickman 1991). Our ability to teachis enhanced with our agility to adjust. In education, the same size does not fit all. Agility is the Proceedings of the 2009 American Society for Engineering Education Pacific Southwest Regional Conference

a number of campuses have begun to offer technological literacycourses for non-science majoring students 4. There are four standard models of technologicalliteracy courses as explained by John Krupczak and Dave Ollis: 5 1. The Technology Survey course. 2. The Technology Focus Course that focuses on a particular technology area. 3. The Technology Creation Course (a course with design emphasis). 4. The Technology Course that Critiques, Assesses, Reflects, and/or ConnectsHope College and Mission College both offer Type-1, the Technology Survey Course designedfor non-science majors.

Another study performed by Keeton [5] found out that instructionalstrategies that promote an environment of learning, supports and encourages inquiry, broadensthe experience of the subject matter and elicit active and critical reflection by learners is areasonable expectation for teaching a class online or not. In our case most of the argumentsgiven by [4] and [5] were accomplished. Simply put, we came to the realization that a projectoriented course in engineering is not a bad idea, group work was mandated and encouraged anddefinitely we had a great level of interaction online. Data analysis was by default the mostimportant aspect of the course because of the nature of the class.However, Bonk [6] found out in a survey that between 23 to 45

The seniors are also asked to consider themselves teachers andmentors of the younger students. In one group, the younger students were not treated as equalsand the faculty members did not intervene in time to remedy the problem. The younger studentswere demoralized and hated being part of the team.

This is particularly useful when it is done consistently and isevaluated formally as part of the student's academic performance. Assignments that have beenused to do this successfully include a one page essay where students describe why they areinterested in their major and what aspects of possible careers interest them after a short lecture onthe possibilities. Another activity involves a lecture on resumes, their content, and how tostructure them to be concise and attractive, followed by an assignment requiring students tosubmit a resume for critique and scoring.
