A computer simulation in mechanics teaching and learning: A case study in circular motions

Abstract

A computer simulation program has been developed and is used in teaching and learning for circular motions. The program can illustrate a moving particle with its position, velocity, and acceleration. It can also draw the angular position‐time figure, angular velocity‐time figure, and angular acceleration‐time figure. Students were divided into 4 groups: A, B, C, and D. Group A used only traditional teaching methods without computer simulations. Group B used 20% of class time to see demos of the computer simulations that were controlled by instructors only. Group C used 20% of the class time in using the simulation programs which were controlled by the individual student. Group D used 20% of the class time to see demos controlled by the instructors and complete an in‐class handout that was closely related to the simulations. The results showed that Students in Groups B, C, and D did better on the examination. This suggested that the computer simulations helped students understand the motions more clearly. Students in group D had the best test scores and the most positive responses to the teaching and learning. This suggested that a handout closely related to the computer simulations would greatly help students understand the topic more precisely. Only students in Group C could control the simulation by themselves, but the learning result of Group C was not the best. This suggested that many students did not know how to learn through interaction with computers. Most of the students learn more from the demos controlled by the instructors and a closely related handout. © 2015 Wiley Periodicals, Inc.

Designing web‐games for transportation engineering education

“…We did not face the issue reported in reference , where the students did not know how to use the program (games in our case). The possible reason is that we included an introduction to how to play at the beginning of each game.…”

“…No quantitative results were reported, but the author qualitatively observed that the interest and understanding on the subject were improved. Lee and Hwan developed a computer simulation program to teach circular motions and conducted detailed comparisons. They concluded that most students did not know how to learn from simulation by themselves, while they can learn more from a demo controlled by the instructors.…”

Monte Carlo method to explain the probabilistic interpretation of atomic quantum mechanics

“…When physical problems require a complex mathematical formulation, the numerical approaches are straightforward procedures and the computer simulation became a very convenient teaching tool to help students visualizing the solutions [20]. Such connection between quantum mechanics description and computer simulation is clearly stated [21][22][23].…”

Interactive computer simulations for standing waves

“…Moreover, improving the teaching‐learning process includes expanding the technology used for developing computer simulations and providing rapid access to the virtual physics laboratory. Furthermore, in the last three decades computer simulations have become compulsory and powerful devices in educational process because they are able to support educational activities such as easy learning and the study of various physical laws and phenomena .…”
