Although I do not agree with most of his rants, when he actually gets to the material he is a good teacher. His exams and homework are fair. The only reason I didn't get an A is because I didn't do one of the assignments worth 5% of my grade.","source_url":"https://www.ratemyprofessors.com/professor/469998","quality_rating":4.0,"difficulty_rating":2.0},{"observed_at":"2026-09-07 16:09:59.676563+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTE2OTQ3MDYw","source_instructor_id":"rmp:469998","instructor_name":"Richard Shaten","course_label":"AAE671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2010-04-04 17:44:30 +0000 UTC","comment":"He teaches through stories from history and current events which helps keep students' attention. Homework is easy and he gives lots of help if you need it. Quizzes are a little hard, but fairly graded. He is always willing to accept an incorrect answer if it has a good argument behind it. I don't like economics, but I liked this class a lot.","source_url":"https://www.ratemyprofessors.com/professor/469998","quality_rating":4.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:09:59.676563+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTE1NzY4NDY5","source_instructor_id":"rmp:469998","instructor_name":"Richard Shaten","course_label":"ECON671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2009-05-05 14:41:28 +0000 UTC","comment":"Professor is smart and knows his stuff well. Other than sometimes diverging to his own little world, he is very clear and concise. I was expecting the course to be deep and hard, but it was really easy. Just go to class and take GOOD notes. Later review your notes and you'll get an A for sure.","source_url":"https://www.ratemyprofessors.com/professor/469998","quality_rating":5.0,"difficulty_rating":1.0},{"observed_at":"2026-09-07 16:03:28.211098+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2NjI5MDIw","source_instructor_id":"rmp:2190069","instructor_name":"Sheldon (Xiaodong) Du","course_label":"ECON671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2022-09-06 05:43:44 +0000 UTC","comment":"He looks so busy but I have no idea what he is doing.","source_url":"https://www.ratemyprofessors.com/professor/2190069","quality_rating":2.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:03:28.211098+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2NTczMTU3","source_instructor_id":"rmp:2190069","instructor_name":"Sheldon (Xiaodong) Du","course_label":"AAE671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2022-08-09 03:10:00 +0000 UTC","comment":"Too many knowledge points but not well structured","source_url":"https://www.ratemyprofessors.com/professor/2190069","quality_rating":2.0,"difficulty_rating":2.0},{"observed_at":"2026-09-07 16:03:28.211098+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2MjYxMTU4","source_instructor_id":"rmp:2190069","instructor_name":"Sheldon (Xiaodong) Du","course_label":"AAE671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2022-05-06 03:30:22 +0000 UTC","comment":"Just read slides","source_url":"https://www.ratemyprofessors.com/professor/2190069","quality_rating":1.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:03:28.211098+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTMyOTE0NzU0","source_instructor_id":"rmp:2190069","instructor_name":"Sheldon (Xiaodong) Du","course_label":"ECON671","course_id":"AAE/ECON/ENVIRST/URBRPL 671","course_uid":"course_32a01851a4d9ed4a29a4cfa9","review_date":"2020-02-17 18:24:53 +0000 UTC","comment":"Professor Du is a pretty good teacher and gives good lectures.

Useful real world applications makes it more interesting. Group presentation, two midterms, and an optional final. He's an extremely fair grader. Easy A if you show up to lecture and do a few homework assignments.","source_url":"https://www.ratemyprofessors.com/professor/2190069","quality_rating":4.0,"difficulty_rating":2.0}]
