6 Chapter 1 Introduction The Course Syllabus ECE 3001/Navi 3001/ECE3201 Electronic Projects Fall Semester 2016 Compass Curriculum Perspective This course is a Navigate course in the Compass Curriculum. Navigate courses provide UCCS students with a common educational experience at the upper division level that broadly expands their perspective beyond their major discipline. An objective is to engage students actively in applying and integrating knowledge, which is drawn from a range of disciplines and includes advanced-level critical thinking. An objective of Navigate courses is to promote curricular and intellectual connections between students coursework for the Compass Curriculum and the work they do for their academic majors, while providing students an opportunity to integrate their learning, ideally beyond their disciplinary area of study. Navigate courses help you learn about: How academic knowledge and skills can be applied to solve practical problems outside of your disciplinary area of study. This is the knowledge in action component of the course. Intellectual and curricular intersections between your major coursework and other areas as a way to integrate and apply learning Explore what it takes to work with different types of people with different perspectives Essential Learning Outcomes: Apply and integrate knowledge from a range of disciplines, including interdisciplinary or crossdisciplinary research Gather, critically analyze and evaluate quantitative information within relevant disciplinary contexts Gather, critically analyze and evaluate qualitative information within relevant disciplinary contexts Demonstrate the core ethical principles and responsible methods of your discipline Course Description Designed for non-engineering majors. In the Fall semester, the principles of How We Communicate are introduced through hands-on building and testing of radio circuits. In the Spring semester, the principles of How We Control are introduced through hands-on building, programming, and testing of micro-controllers. The history, personalities, social and cultural impacts, economic and business impacts, and sustainability issues are integrated into the lecture material for the target technology. Approved for Compass Curriculum requirement: Advanced Core. Prer., Freshman level science course. Semester Emphasis Details This offering of Electronic Projects will emphasize analog circuit design for communication receivers. Practical experience in breadboarding radio circuits will be obtained starting from little or no experience in circuit theory. To take this course it is assumed that you have a strong desire to build and tinker with electronics. Today this is what is known as being a Maker. Throughout the course you will also gain experience with soldering. To start with, however, we will work with solder-less breadboards. 1 4 ECE 3001 Electronic Projects
