Average Course Rating

(4.03)

This course challenges students with laboratory projects that are not well-defined. Students work in groups to develop an effective approach to experiments. They identify the important operating variables, decide how best to obtain them using measured or calculated values. Based on their results they predict, carryout, analyze and improve experiments. Each student analyzes at least two of the following biomolecular projects: bioreactor, biocatalysis and membrane separation and one of the projects in EN.540.311. In addition to technical objectives, this course stresses oral and written communication. In addition to technical objectives, this course stresses oral and written communication. Students will have additional meeting times with the instructors and outside of class.

Fall 2012

Professor: Lise Dahuron, An Goffin

(4.5)

The best parts of this course were the interesting subject material, good lectures, and labs. The negative aspects of the course were the very difficult exams and complex math that was involved in a lot of the assignments. Some students also said that the lectures were too similar to the textbook and that there were not enough examples. Students suggested using a better textbook and giving out practice exams or more practice problems to study. Students also wished the class had covered more practical applications. Students considering this course should expect a difficult course that is dependent on knowing MATLAB. Students said that overall this is a difficult class, but the textbook is a great resource.

Students enjoyed getting practical experience with chemical engineering and getting feedback from professors. The negative aspects were that students did not receive much guidance for labs and the manuals were not helpful. Additionally, lab equipment often failed, making experiments difficult to complete. Students suggested updating the lab manuals and making sure the TAs know how to use the equipment, so that time is used more efficiently. Students should know that this course is writing intensive and that the lab reports can take a very long time to complete.

Students enjoyed applying skil s and knowledge they had learned in previous courses. They learned about professional and technical writing, and appreciated getting feedback from the writing professor. Some said that the class was poorly organized and that often the TAs did not know what was going on in the labs. Also the two professors graded inconsistently. Suggestions for improvement included updating the lab manual and having a more consistent grading protocol. Students considering this course should 59

Students enjoyed getting hands-on experience and working in groups. The negative aspects of the course included the TA and professor’s lack of knowledge on using the lab equipment. Students also said that there was little guidance from the manual or the TAs. Suggestions for improvement included a better lab manual and more guidance on procedures. Students should know that the course is a lot of work and lab reports can be very time-consuming.

Fall 2013

Professor: An Goffin

(4.0)

The professor was one of the best aspects of this course. Students thought that she taught the materials thoroughly, and that many of the materials discussed in class were put into real-world context, which made the information easy to grasp. Students did believe that the lab was a bit incongruous as it did not apply to what they learned in the lecture. They also thought that the lectures relied too heavily on the textbook, so they recommended using a different, more up to date book instead. They also thought that the lab should be updated and moved to earlier in the semester. Prospective students should read the materials before class and attend every lecture to hear al the details that may end up on the exams. The

Students praised the course’s labs, which pul ed together knowledge students had gained throughout their time at the school. Students’ issues with the course included finding that some of the equipment didn’t work correctly, while another student disliked not learning how to use al of the equipment. Suggestions for improvement included providing access to and instruction for newer equipment. Prospective students should know that the course was chal enging and that it tested much of what they had learned in earlier courses.

Fall 2013

Professor: Chemical and Biomolecular Engineering Lab

(3.6)

Students praised the labs that were examples of practical applications of Chemical and Biomolecular Engineering principles, and felt that the labs helped them improve their writing skills. Some students found the multiple instructors in the course led to inconsistent instruction. Students also found the course was time consuming and had a high workload. Suggestions for improvement included providing better guidance from instructors on how to complete assignments. Prospective students should know that the course had a heavy workload and required group work. Students also found they couldn’t procrastinate in the course as lab reports required a significant amount of time to complete.

Fall 2014

Professor: Lise Dahuron

(4.0)

Students most appreciated the opportunity for practical experience and to learn science writing provided in this course. They thought the biggest drawback of the class was the large amount of work outside of class sessions. Students also felt courses could have been improved with better guidance for 65assignments and the use of lab equipment. They thought it was valuable for potential participants to know that finding fellow students they could collaborate with effectively in lab groups was important.

Fall 2014

Professor: Lise Dahuron, Sharon Gerecht, Marc Ostermeier

(3.93)

Students thought the best aspect of this class was the labs where they had the opportunity to practice designing experiments and to gain practical experience. They felt the biggest drawbacks for the course were the difficulty of completing lab reports and deficiencies in laboratory equipment. Students thought the course could be best improved with a more even distribution of the workload over the duration of the class. Students felt it was most important for prospective participants in this class to know that they should be certain to set aside sufficient time for completing lab reports.
