An Online System to Help Students Successfully Solve Statics Problems

Abstract

Engineering Statics is often the first core engineering course that many students take. Most students do not find it to be conceptually difficult, but are often overwhelmed by the myriad of small decisions that they must get correct if they are going to successfully solve a problem. Too often, this causes a student to question if he/she should continue to study engineering. Described herein is an online computerized leaning system, called ARCHIMEDES, which helps students overcome the major obstacles to success in Statics. The system allows the student to draw free- body diagrams and write free-form equilibrium equation in the same way as they would with paper and pencil. At key times in the process, the system assesses the student's work and gives immediate feedback on the correctness, completeness, and consistency of his/her solution. The instant feedback allows students to correct errors early and avoid the fruitless efforts that result from errors made during the early parts of a solution. A pilot study has been conducted to quantitatively assess the effectiveness of the new system in helping students successfully solve problems in Statics; over 65% of the students felt that ARCHIMEDES helped build their confidence in solving Statics problems. Additionally, 65% of the students also felt that using ARCHIMEDES would help them improve their grade and half wanted to have it available for the remainder of the semester.

Introduction

Engineering mechanics, comprised of Statics, Dynamics, and Mechanics of Materials, is a sequence of lower-division courses that are the first real problem-solving courses that many engineering students encounter. Most students do not find these courses to be conceptually difficult; they sit in lecture and feel that they understand all the material, but are unsuccessful in applying the methods on their own to new problems. They are often overwhelmed by the many small decisions that they must get correct in order for them to successfully solve a problem. The resulting frustration often causes a student to question if he/she should continue to study engineering.

In many universities, Statics is taught almost the same way today as it was nearly two decades ago. A typical Statics course consists of lectures given by a professor, in which the students are given the fundamental tools and techniques; lectures often include the solution of sample problems. Recitation sessions follow, in which students practice solving problems, with an instructor available for help when requested. Students then are supposed to hone their skills by solving several problems (from the book) for homework. Several changes have been proposed to these methods1,2, with varying degrees of success.

After teaching Statics for several semesters, it became clear that sometimes homeworks helped students as intended (usually for the good students). Unfortunately other students rarely completed the problems satisfactorily. When questioned why their work was incomplete, the students would often say: “I didn’t know what to do”. After further questioning, it became
