Miniature Open-Channel Weir for the Standard Classroom: Implementation and Assessment Abstract
A miniature open-channel flow system with weirs was used to teach characteristics of open-channel flow, flow control and measurement in a Civil Engineering Water Resources Engineering class. One class was given hands-on active learning; the other class, as a control will receive traditional lecture in the following semester. Preliminary analysis of the results shows that concept inventory performance for students who received the hands-on active learning exercise is improved by 52.1 % over their pre-test. In addition, a flashlight survey discloses that 29.5% of students were very satisfied while 65.9% were satisfied with the hands-on active method compared to the traditional lecture method.
According to the learning cone  shown in Fig. 1, students retain knowledge better by seeing than by only reading or hearing. Having that as a motivation, Van Wie and coworkers  have developed portable desktop learning modules (DLMs) for chemical engineering and have implemented nontraditional learning pedagogies: namely, cooperative, hands-on, active and problem-based learning. Cooperative learning has been implemented by forming small groups of students to work on worksheets, quizzes, homework and projects. Hands-on learning involves groups of students observing theoretical principles in action with the DLM hardware. Active learning is promoted by group exercises in the form of worksheets which require students to do derivations and calculations and to discuss implications. Problem-based learning involves open-ended group design projects.

To our best knowledge, there is no study done on the use of open channel as a desktop learning module in the literature. Van Wie and his group has been designing desktop modules and different cartridges like venturimeter, orifice meter, Reynolds’s experiment, double pipe heat exchangers, shell and tube and extended area heat exchangers, packed bed in chemical engineering area. Now, goal of the research group is to extend those
