The course is a good introduction to chemical engineering concepts. Students enjoyed working in smal groups to review and reinforce the material. The downsides were the heavy workload and the timing of assignments. Some students suggested that the homework assignments should be shorter and graded less harshly. Students should know that the course is very chal enging. Students are recommended to

Students praised the course as intellectually challenging with an approachable instructor. Students disliked the course’s homework, which they found took a long time to complete. Suggestions for improvement included a desire for a structure for the course, including a chance to go over more example problems with students. Prospective students should know that the course was difficult and challenging, but it was a good introduction to the field.

Students most appreciated the enthusiastic teaching of the approachable instructor for this class. They also enjoyed that the course gave them a better perspective on the work of chemical engineering. Students thought that one of the course’s chief drawbacks was that the course felt disorganized at times. They also thought that the workload was weighted to the end of the class and that coverage of the final subjects of the class seemed rushed. Students found that the course could be improved with having a greater number of problems presented during class sessions. Students felt that it was useful for potential participants in this class to know that the course was challenging and that preparation for exams was accomplished most effectively through practicing problems.

The best aspects of this course included the instructor’s enthusiasm and the ways in which the instructor tied the subject material into the lectures and assignments. Some students felt that the amount of homework assigned was excessive. One student felt the PILOT sessions were not useful since the examples solved were not 100% representative. Suggestions included providing more consistent tests and varied examples, as well as incorporating more graphics/videos to show how chemical engineers analyze processes in the real world. Prospective students should know this is a good course in which to determine whether chemical engineering is one’s ideal focus or not.

The best aspects of this course were the broad introduction to the field of chemical engineering, the PILOT sections, and the hands-on problems. Many of the problems had clear relationships to designing systems in the real world. The worst aspects of the course were the group homework, the rapid pace of the class, and the disorganization of in class notes. Students also cited the short notice and unreasonable expectations of the final project as a major detraction from the class. Suggestions for improving the class include allowing students to form their working groups or doing away with group homework, more examples shown in class, and additional programming instruction. Prospective students should know that this course requires a fair time commitment, but wil give you a good idea of what the ChemBE major is like and if it’s for you.

(4.64)

The best aspects of this class included the solid overview of the field of chemical engineering that the course provided, and the thorough and enthusiastic professor. Students appreciated the social nature of the class, fostered by the weekly PILOT sections and the emphasis on col aboration for homework assignments. Many students agreed that an occasionally mismanaged lecture pace meant ignoring more difficult example problems and important concepts, which made the homework more difficult. Further, students suggested that they would have appreciated more explicit instruction on MATLAB, and more guidance on the open-ended final project. Prospective students should have a solid background in chemistry, physics, and mathematics, and be prepared for group work.
