Pre-laboratory activities are essential components of the teaching lab and there is a growing body of research examining the benefits of adding online components in chemistry teaching labs. Most undergraduate students now watch pre-lab instructional videos - whether prepared on-site or available commercially - which have shown significant potential to improve student learning outcomes. Pre-lab questions and quizzes are also being moved online to improve feedback and save time for students and instructors. Interactive simulations (aka virtual labs) have been shown to facilitate student performance but are often limited to general chemistry concepts.<br/>Here we present results of integrating online pre-lab activities in the introductory organic lab course at a large public institution with the large class sizes (≥ 450 students) over the last two years. Student feedback prior to the study indicated that much anxiety arose from an overwhelming procedural focus and a lack of confidence in using lab equipment exacerbated with a fear of making mistakes or losing points. To better familiarize students with techniques/glassware we implemented online organic technique simulations (Labskills - developed at the University of Bristol) where students and carry out experimental before entering the lab. Student performance and surveys indicate that student confidence and attitudes towards lab improved as a result of better preparation and understanding.<br/>
