I have developed a teaching style that emphasizes more than just rote memorization. Students need to be encouraged to think critically by applying familiar mechanisms to new situations.


After being heavily influenced by the education he received at Haverford College, Andrew Karatjas pursued his Ph.D. at Pennsylvania State University with a goal of teaching at the undergraduate level.

Since 2006, Karatjas has taught a variety of chemistry courses while focusing on organic chemistry. With a background in organic synthesis and methodology, he has done research in the methodology of indoles and related natural products as well as hydroboration methodology.

More recently, Karatjas has developed a focus on chemical education research, specifically in looking at student self-assessment and how that affects performance in courses.

Most of his work has focused around student learning and looking for ways to improve student learning. As an organic chemist, he often teaches what is regarded as one of the most difficult courses that students take.

Too often, organic chemistry is thought of (and presented) dryly and has gained a stereotype as a class used to “weed out” pre-med students. Karatjas has developed a teaching style that emphasizes more than just rote memorization. Students need to be encouraged to think critically by applying familiar mechanisms to new situations.

For example, when he teaches organic reactions, he presents the material organized by reaction mechanisms. Karatjas emphasizes to students that memorization will only take them so far in the course. When he teaches the chapter on nucleophilic acyl substitution, he makes sure students realize that while this chapter has more than 20 reactions, most of the reactions use two general mechanisms. Therefore he attempts to get students to learn reactions by mechanisms and not memorization as it will allow them to apply what they have learned to new reactions.

By challenging the students in this way, it is Karatjas’ hope that students can transfer this learning to other situations (whether school related or not).

Through different strategies in the classroom as well as his research in chemical education, Karatjas’ students are well prepared for their future coursework and careers of choice.
