Draw sketches of components on the board, use textbooks and internet resources to show them the pictures and videos of components either in good condition or those that have failed during normal operations or in service. 2. Bring real components (whether failed or in good condition) as educational aids to the classroom. This is not always possible as some components may be heavy to carry. Page 22.924.6 3. Divide students in small groups and bring each group in to a laboratory that contain machinery (for example pumps

For instructors, it is also an obstacle toeffectively teach fundamental robotic concepts. Virtual robot simulator has been explored bymany researchers to create a virtual environment for teaching and learning. This paper presentsstructure of a course project which requires students to develop a virtual robot simulator. Thesimulator integrates concept of kinematics, inverse kinematics and controls.

It was developed inresponse to: 1) the increasing need for engineers and scientists to have a global perspective ofwater resources challenges; 2) the need for engineers and scientists from across the world towork together to develop solutions to our global water resources challenges; and 3) the lack ofshort-term, affordable international experiences available to engineering students.

Rigorous independent researchat the undergraduate level is still relatively uncommon in the U.S.; is typically limited to thestrongest students or students in specifically targeted populations 1, 2, 3; is most common in fieldsinvolving laboratory science; and is least common in non-laboratory social sciences andhumanities, with engineering fields somewhere in between 2. Ultimately, this means that studentsentering graduate engineering or construction-related programs of study typically do not havesignificant prior exposure to or experience with the means and methods for designing andimplementing independent research.In response to this knowledge gap, faculty

We have found in previous courses that conducting experiments and solving theequations for devices that they can handle increases the students’ understanding. We use 3different methods to solve the equations for 2 reasons, (1) some students relate better to each ofthe methods and (2) by the time it has been done 3 times most students will finally understandwhat is being done. This first project deals with a one-dimensional (1D), steady state heattransfer conduction and convection problem, which is solved analytically, numerically andfinally experimentally. This is
