Drawing Lewis structures
just became a lot more fun

Our custom built Lewis structure drawing tool allows students to quickly and intuitively create structures on any mobile device.

Not only does it allow students to draw, but it was designed from the ground up to help students visualize the relationship between structure and molecular shape.

The results

We tested Chem101 with 2,000 students across 8 schools. 40% of students said using the product made them more interested in chemistry and we measured up to a 200% improvement in student learning gains.

Students

My students were having so much fun with Chem101, I actually had to kick them out at the end of class by telling them they could play with it at home at any time. In addition, their normalized learning gains on the common final exam were significantly higher than those of students in sections that did not use the app.

Kathleen Kolbet

Professor of Chemistry,

Truckee Meadows Community College

I really enjoyed using Chem101! I felt like I was playing a game on my phone instead of doing homework. This app is effective, designed well, and makes learning chemistry fun!

Christina D.

Student in CHEM1040,

University of Cincinnati

Chem101 allows my students to draw Lewis structures intuitively with very little learning curve so more time can be spent learning chemistry and less time learning the program. My students and I both enjoyed having a large pool of practice questions to choose from to master the material.

Daniel Waddell

Assistant Professor of Chemistry,

University of Cincinnati

Compared to other websites such as Sapling, Chem101 was simpler to navigate, easier to complete specific activities such as drawing Lewis structures, and overall a better experience for learning. I also preferred Chem101 to clickers simply because it is more interactive than choosing a multiple choice option.

Zack M.

Student in 09-105,

Carnegie Mellon University

While testing Chem101 in my class, I noticed students were engaged and I never heard the typical “huh” I normally obtain when I ask them to pull out their clickers. This app is a terrific tool for students and it would be great if it could be expanded to also cover other topics in chemistry.

Daniele Ramella

Assistant Professor of Chemistry,

Temple University

I enjoyed using Chem101 for Lewis structures because it really helped me visualize where everything needed to go. It makes it easy to explore other possible Lewis structures and fix mistakes. A dynamic app like this is great for visual/kinesthetic learners.

Duquesne University

It was a delight to hear the "buzz" of students talking to each other as they did the questions. Students also seemed to enjoy using Chem101 and learning from the app. I would highly recommend it to anyone who teaches a class in general chemistry, particularly in a large lecture hall.

Ruben Savizky

Professor and Lecturer of Chemistry,

The Cooper Union, Columbia University

Chem101 was the best app that I have ever used for school. It was clear and explained things very well when answering questions. Using the app in class made learning chemistry fun and easy.

Justin Weinberg

CEO

Justin is the visionary behind 101 and has been teaching forms of math and science for nearly a decade as a tutor and a university TA. Prior to 101, he created Chem Pro, a mobile app with over 500K downloads that is designed to help students learn chemistry with video lessons. Now, Justin is leading 101 to bring its classroom engagement tools to college STEM courses across the country. Justin is a PhD candidate in chemical engineering at Carnegie Mellon University and is a recipient of the prestigious National Science Foundation (NSF) Graduate Research Fellowship.

Igor Belyayev

CTO

Igor leads technical development at 101, responsible for bringing our novel interactive experiences to reality on iOS and Android. He's worked as a mobile developer at startups like Jet.com and Hackerati, as well as media companies like The Huffington Post and Viacom. Igor holds a bachelor's degree in mechanical engineering from The Cooper Union. Igor and Justin have been working together since 2011 when they originally teamed up to develop the first Android version of Chem Pro.
