Fall 2012

Professor: John Wierman

(4.12)

The best aspects of this course were that the lecture materials were available online and that the professor offered a lot of extra credit assignments. In addition, they said the TAs were very helpful. Some students liked the professor’s teaching style, while others found the PowerPoint presentations boring. Many students wanted to have access to homework and exam answer keys for studying. Students need a good knowledge of calculus before taking this course. Students suggested taking advantage of extra credit opportunities and forming homework groups.

Students believed that the best aspects of this course were the interesting concepts and materials covered in class. The professor was very passionate about his subject and real y monitored students’ efforts to help those who put in the effort, which he would use when determining (and sometimes boosting) grades. Students found the exams to be rather difficult and did not like that many of the concepts were taught using PowerPoint slides. Instead, students suggested that using Blackboard instead of PowerPoint and providing additional study materials like old exams would help them study more effectively. Prospective students should be prepared for a chal enging but interesting course where effort is rewarded and supported. Students are encouraged to complete all of the extra credit opportunities and be prepared to work hard.

Students thought the best element of this course was the interesting material taught by an enthusiastic professor with a sense of humor. Students thought the biggest drawback of the course were the lectures, which students said could have placed less emphasis on explaining material with PowerPoint slides and more time on reviewing example problems. In addition to providing more practice problems, 14students thought the course could benefit from having exams that better matched the problems offered in homework assignments. People considering taking this class should know that an understanding of calculus would be useful, students said.

The best aspects of this course included the many extra credit opportunities, downloaded presentations for students to study, and the instructor’s regular jokes. Some students felt the instructor should have incorporated more examples during his lectures. Also, students felt the exams were excessively difficult and too long to complete within the expected amount of time. Suggestions included posting answers to the practice exams online and providing more examples in class. Prospective students should know this is a difficult course.

Spring 2014

The best aspects of this course included the interesting subject matter, the fair grading policy, and the chal enging work. The joke of the month contest was also mentioned as a favorite with students. The worst aspects of the course were the ineffectual lectures, the lack of solutions to practice questions, and the heavy workload. Working through problems in class, providing solutions to practice questions, and a more engaging lecture were suggested improvements to the course. Prospective students should have some experience with upper level math, stay on top of the homework and studying, and take advantage of all extra credit opportunities to increase their probability of a passing grade. 14

The best aspects of the course were the interesting course material covered and opportunities to earn extra credit. Students felt that the professor was not very helpful and found it difficult to study without answers for any homework or practice exam questions. Lectures were hard to fol ow and students felt that they were ineffective. Suggestions for improvement included having the professor lecture using the chalk board and not PowerPoint. Students also suggested giving answers to old exams and having better structured TA sections. Prospective students are encouraged to do al extra credit assignments, to al ocate time outside of class to learn concepts, and to study the textbook. Prospective students should be familiar with calculus and basic probability.
