Problem-solving videos as an instructional aid for engineering education

Abstract

Described in this paper is the use of problem-solving videos as an instructional aid for teaching an introductory engineering circuit analysis course. The instructor prepared step-by-step video solutions, with audio, of classroom examples, homework problems, and examination solutions. The videos were accessed through a website; as a result, they were available to the students twenty four hour per day and seven days per week. Web usage statistics indicate that the students were using the videos extensively as they studied course materials. Student surveys indicate that they believe that the videos were improving their understanding of the course material.

A computer aided learning module for digital control: Description, analysis, test and improvement

“…It seems more relevant in the future, to cut out this long module in small pieces, which the teacher can put in access to such or such moment. Some references underline the importance of videos for problem-solving [11] but it will not be necessary in this module because no practical skills are needed. Besides, some papers show the impact of practical activities [5][14] on motivation and success.…”

Systematic Review of Rigorous Research in Teaching Introductory Circuits

“…Minimal findings reported beyond a suggestion to adopt the teaching method. Nelms, Langford, and Halpin (2005). Problem-solving videos as an instructional aid for engineering education.…”

Hybrid Content Delivery: On Line Lectures And Interactive Lab Assignments

“…The paper examines which technology is more appropriate for synchronous or asynchronous learning, or both. Nelms et al 7 use videos as supplement of traditional lectures and office hours for providing additional examples. The videos allow students to learn the examples at their convenience and preferred pace.…”
