Are Your Students Ready for Lab? 11/5/2015 Presenters: Bill Heslop and Tony Baldwin, Directors and Co-founders, Learning Science Ltd. LabSkills is an online program that prepares students for their lab sessions through assignments inOWLv2, the leading online learning system for Chemistry. LabSkills makes it easy for you to requirestudents to complete laboratory preparation prior to attending lab with demonstrations, interactivesimulations, and quizzes. The newest version of LabSkills PreLabs is an enhanced course with 10 new techniques, plus new mobile-compatible simulations. LabSkills content is easy to assign and is automatically graded. LabSkills is currently used by schools and universities in more than 30 countries worldwide.In this webinar, you will learn how to get your students:-Engaged with practical work-Prepared when they get to the lab-Confident in performing the experiments-Using the time in the lab effectively
