Classroom demonstration module for two and three dimensional force analysis: The montessori based engineering (MBE) model

Abstract

Statics or Engineering Mechanics 1 is a fundamental course for most engineering disciplines and includes topics such as force systems, equilibrium, truss analysis, centroid, and moment of inertia. Statics or Engineering Mechanics 1 is typically taught in the first semester of the sophomore year of the four-year engineering degree. It is usually observed that this is a difficult course for students and the passing rate is 60.7% [1]. The author implemented a variety of methods to reduce the failure rate of students in this class. These methods included some hands-on demonstrations based on the ExCEEd model and the Montessori method of education. Hands-on models when used in combination with other active learning methods are engaging and useful in maintain student interest [4]. The learning materials are one of the two main aspects of Montessori classrooms that are different from the conventional classroom [6]. The use of this method has been limited to K-8 classrooms. In this paper, the authors will describe the classroom demonstration for two- and three-dimensional force analysis, which would be appropriate for use in the Undergraduate Engineering Statics class. Core aspects of the Montessori method, like introducing the color/shape/method scheme with a familiar topic and using the same scheme to introduce a complex topic is done with the intention of making learning accessible to all different types of learners. In this paper the authors introduce the scheme for two-dimensional analysis and then furthers the scheme for three dimensional models. The assessment of this method which shows clearer understanding of the concepts and increased student enthusiasm is provided in this paper. The procedure for making these models, along with textbook examples for use in the classroom are also presented in this paper.
