The focus of the first section is thelearning process, and the second section discusses innovative methods of teaching.Topics included in the “Learning” section include: 1) Focusing on Learning and NotTeaching; 2) Problem Based Learning; 3) Facilitating Group Learning (PromotingAccountability, Linking Assignments, and

Storm cells, tornadoes, and haz-ardous weather cause damage and loss that could be minimized through enhanced radarand longer warning lead times. To study these topics, the program has generated a unique,interdisciplinary research-oriented learning environment that will train future engineers andmeteorologists in the full set of competencies needed to take raw radar data and transformit into meaningful interpretations of weather phenomena.

They also must have a program that includes a curriculum that enables graduates toobtain these objectives.1 There is a list of various program outcomes that must be met. Thecurriculum must “provide an integrated educational experience that develops the ability ofgraduates to apply pertinent knowledge to solving problems in the engineering technologyspecialty”1.

. This point is important because itcan affect the complexity of updating or upgrading the overall system in the future. For thatreason, we start with a basic but reliable core structure that controls a motor, and then we extendit to form an advanced online-controllable system. 1. Core System StructureBuilding a system infrastructure from scratch might involve talking about some details. What isimportant to know is that a simple motor has three states: turn clockwise, turn counterclockwise,and idle. These states can be obtained by constructing a circuit that uses relays to switch on/offthe right motion. Also, the signals that turn a relay on/off can be imported from a computer andcontrolled with a software interface

Implications for teaching andpractice are discussed.Background Even as girls’ and women’s participation in some areas of science has risen considerablyin the past few years, the field of engineering has changed very little with rates of femaleengineering majors estimated at between 18 and 20% 1. Research on the patterns of girls’progression in the science, technology, engineering, and math (STEM) pipeline is wellestablished 2, documenting attrition which begins in middle school and continues throughgraduate school.

This was not an easy endeavor, asexisting activities tended to emphasize one subject over the other, or require a team of teachers(i.e., technology, science, and math) to coordinate over a fairly lengthy period of time. Afterseveral iterations of implementing activities in pilot classrooms, activities that successfullyintegrated algebra and engineering had these qualities: (1) the activities

technological growth has put new demands on engineering and engineeringtechnology educators. Industry seeks graduates with up-to-date technical knowledge. Thehalf-life of an engineer's technical skills − how long it takes for half of everything anengineer knows about the field to become obsolete − is becoming strikingly short [1].The pace of technological change has also imposed new challenges on facultydevelopment and technical currency of programs. Faculty professional development activities and technical currency play animportant role in promoting student learning and success.
