Implementing manipulatives into the classroom to help explain different laboratory testing procedures and their applications can be a useful tool. Using manipulatives is a very time-efficient and cost-effective method for engaging students in active learning either as an individual activity or a group experience. The use of manipulatives encourages free exploration and discussion in either setting by being a "hands-on" activity for students. At the completion of each manipulatives session, students will be able to review and discuss the principles and procedures, including quality control issues, for selected tests used in microbiological testing.
