Microelectronics is a challenging course to many undergraduate students and is often described as very messy. Before taking this course, all the students have learned circuit analysis, where basically all the problems can be solved by applying Kirchhoff's laws. In addition, most engineering students have also learned engineering mechanics: statics and dynamics, where Newton's laws and related principles can be applied in solving all the problems. However, microelectronics is not as clean as these courses. There are hundreds of equations for different circuits, and it is impossible to remember...

Chinese is rapidly becoming one of the most popular foreign languages taught in many countries all over the world; however, it is also one of the most challenging to learn. The standard method of teaching Chinese is often adopted from elementary schools in China, where students learn the language through repetition and practice. Unfortunately, this approach is not very effective for teenagers and adults living in other countries, as Chinese children are already familiar with the spoken language before entering elementary school. In addition, learning through rote memorization is not a good...

Engineering Thermodynamics is a core course for students majoring in Mechanical and Aerospace Engineering. Before taking this course, students usually have learned extit{Engineering Mechanics}-Statics and Dynamics, and they are used to solving problems with calculus and differential equations. Unfortunately, these approaches do not apply for Thermodynamics. Instead, they have to rely on many data tables and graphs to solve problems. In addition, many concepts are hard to understand, such as entropy. Therefore, most students feel very frustrated while taking this course. The key concept...
